Vitruvian (Closed)

Alex could hardly believe this was Amelia. She was usually so demure and shy! But now she was yelling at him, calling him a slut, telling him she'd fuck him even if he said no, saying his ass belonged to her, and all the while she was fucking him like a wild animal, her hand flying and spanking him while she did it.

It was the sexiest thing in the universe. He'd never, ever felt like this. So sexy and slutty and fulfilled and filled and hurt and pleasured, all at once. Her cock, so hard and hot and huge in his tightness, plundered in again and again. He felt like his ass would never close again, and he didn't know that he wanted it to. He wanted it to be open to her, all the time. Whenever she wanted it.

"Yes! I'm your slut, Amelia! yours, forever! This is your ass to fuck! Ohh, and your big cock fucks it so fucking good, sis!" He felt her getting even wilder, an inkling of what was coming rising in his mind. "Give me your cum! Fill your whore brother with you jizz, sis! Please! Fucking fill my ass with your cream and make me yours!"

He felt it then. She pushed in as deep as she could go and screamed and he felt it. A burst of warmth in his core. It was hot, heavy, thick and sticky, and he...loved it. "YES! Yesss...that's it! Give me all your cum! Fill me up! Fill me! Flood my boypussy with your cum!" He tried to flex his sphincter, squeezing her cock, wanting every bit of her jizz that he could get.

God! This felt so wonderful! Was this was she felt when he came in her? No wonder she wanted it so much. "Oh, Amelia...baby, lover, sister...your cum feels...feels so wonderful inside me," he said, almost lost in the sensations.

Alex reached back, grabbing her hands and pulling her until she was laying atop him. Then he reached up to stroke her head, petting her hair. "I love you so much, and I love what you do to me, sis. I can't get enough of this, of us."
 
Oh, fuck. Just . . . god. Amelia slumped over, laying on top of Alex as he stroked her hair gently. She felt . . . so good and so weak. Her tired brain, just firing back up after its animalistic jaunt, just barely understood what he was saying. "I love you too, Alex . . . this is so wonderful . . . never dreamed I'd have this with anyone." And it was true. She'd never thought she'd find someone who would accept her, love her, the way she was. And to have that person be her brother was almost unreal.

She kissed his hand as it passed by her cheek again, and then smiled weakly at him. "I can't imagine what I'd do without you now." Even though her legs were shaking and her whole body felt as though it were made of paper - wet paper - Amelia pushed herself up a little and pulled slowly out of his ass with a groan. It felt so cold now that she was out of him, and she looked down to see a few globs of her cum ooze out following her cock. Even that was hot.

Her smile grew a little, and she looked down at him. "I meant what I said, Alex. Get cleaned up, and I want to feel your cock in me."
 
"I hope you never have to find out," he replied in a soft voice to her uncertainty about what she'd do without him. It was a good question. And one that may have to be asked. It would be tricky for them to stay together after high school, wouldn't it? And if they weren't...he didn't want to think about it. Not now. It was too grim.

He moaned as she pulled back and her softening cock slid out of him, finally coming free with a wet, slurping pop. "Ahhhh...ahh, God..what a terrible feeling...though I guess...I still feel kind of sexy." As she ordered him to get cleaned up and get back so that he could fuck her, Alex felt a surge of strength that came through the dreamy feeling of what had just happened. "Oh, little sister. There's nothing I want more right now that to be buried in your sexy little body."

Alex clenched his ass, hoping not to leak on the floor as he moved, and rose from the couch. He turned and leaned down to kiss his sweet, slutty sister on the lips and then made his way to the restroom. As he cleaned himself, quick but thoroughly, his mind went over what had happened again and again. So fucking good. But she'd made his ass hurt spanking him like that. And while he liked it...he'd have to pay her back. Oh, and she wanted him to, the naughty little thing. Fuck, she was so damn sexy!

His cock was half-hard when he emerged from the bathroom, eyes smoldering. Alex strode over to his sister, kneeling on the couch as he pused her down against it and kissed her hard. "You want this cock to fuck you, don't you, little sister?" He kissed her again. "Use your mouth, baby sis, and make your big brother hard and show him just how much you want to be fucked."
 
While Alex was cleaning up, Amelia flopped on the couch, just getting her breath and her strength back. That had been . . . intense. Glorious and so hot, but intense. With anyone else she would have been far too nervous to even think of that, but with Alex, it was so much more relaxed, and trusting. And hotter, because it was so taboo.

He came out of the bathroom, already getting hard, and Amelia bit her lower lip. He looked so amazing, and the expression on his face . . . she shivered. And when he pushed her down on the couch, she went easily, kissing him back as hard as he kissed her. "Yes, Alex, I want it . . . want your cock in me."

Nodding at his orders, Amelia squirmed around and knelt down, her hands going to his shaft before she leaned forward, opening her mouth to try and get her brother hard for her. "Anything you want, Alex . . . you know I want to have you fuck me so much it's almost making me crazy." And without saying anything else, she wrapped her lips around the head of his cock, sucking and licking at it with a hunger that almost bordered on desperation.
 
"Mmm, ohh, you dirty little cocksucker," Alex moaned as his sister greedily slurped and sucked on his dick. "God, you..mmmm, fuck...you were born to do this, you sweet, sexy, nasty slut of a little sister." Her answering hum made him moan, his hands sliding through her hair, resting on her head. "Suck your brother's dick, you incestuous whore." He took in a hissing breath, "Oooh, yes. That's it. Mmm, that's it, little sister..."

He could feel himself growing in her wet, living mouth. Her tongue rasped and rolled over him as she took more and more of his swelling length into her little mouth and throat. Alex stared down at her, watching her as she took his deep in her throat, looking up at him with those lustful, adoring, cute eyes.

Alex started to move his hips, pumping his cock in and out of her mouth. She stilled, looking up at him, moaning around his dick as he slowly, deliberately fucked her sweet face. He grimaced and groaned, picking up speed. God, he wanted to just fuck her face rough and blow his cum down her throat. Fuck! So hot! But...not yet. Not yet.

"Fuck! You little slut! Got me so fucking turned on I'm tempted to just..mm! Just cum in your mouth and make you drink all my cum! And you'd just fucking LOVE it too, wouldn't you, little sister?" Alex grinned down at her. Then he stepped back, his cock coming out of her mouth with a faint but audible pop. "But I need that pussy more. On your back and spread your legs, slut. Big brother's big cock needs to fuck your little pussy. Right. Now."
 
She felt Alex pull out of her mouth with regret so sharp that it was almost physical. Amelia pouted up at him. "I would have loved to drink your cum, big brother." She didn't quite dare to ignore his orders, however, and crawled up onto the couch. As she turned around, stretching out on her back, she smiled at him broadly. "But I'm just as glad to have you fuck me instead."

Amelia spread her legs - but not the way he'd expected. She brought them up, perpendicular to her body, then opened them in a V, her cock standing straight and hard between them. One of her hands reached between her legs and around her cock, brushing it with her wrist and drawing a groan from her, to spread open her pussy lips with two fingers.

"I want your cock in me, Alex. Please, fuck my sweet little cunt?" Amelia put on her best little-girl voice, and her best little-girl-asking-for-a-treat voice (something she'd grown very adept at over the years) and batted her eyes at him.
 
A visible tremor ran through Alex as she looked at him with wide, innocent eyes, her lashes fluttering, begging him to fuck her in the same voice that a little girl might use to ask for a lollipop. "Good. God."

His cock felt like it was trying to grow even larger and harder, as though it might split his skin. He felt a sudden urge to just plunge into her and ravage her sweetly offered body for every bit of pleasure it could give him. He closed his eyes, letting this fresh spike of arousal spread through him. "Amelia, you are just the sexiest little slut ever."

Alex smiled, "Don't worry, sweetie. Big brother's going to give you just what you want." He wasted no more time, setting her legs on his shoulders, lining up, and thrusting deep into her cunt. "AHHhhhhhh! Oh, yes." He started to move, pushing far into her, emphasizing each word with a hard thrust. "Big. Brother's. Going. To. Fuck. You. Raw."
 
"Ohhhh, Alex!" Amelia felt her toes curl as Alex thrust into her, her eyes closing tightly at the feeling of her brother sliding into her. "Yeeeees, fuck!" Her hands gripped the couch cushions, almost tearing the fabric with her nails. "Fuck my tight cunt, big brother! Give me that hard, hot cock!"

Gasping with each thrust of Alex's cock into her, Amelia bit her lower lip. It felt so good! She could barely think, just feel. Just feel his body inside of hers, his hands on her legs, as he fucked her. "I want you to fuck me raw, Alex! God, I need it!"
 
"You DO fucking need it, don't you, you incest whore?" Alex would have gone into a rage if he heard anyone talking to his sister like this. But now, it was the most natural thing in the world. It was right. It sounded good, it felt good, and ohhh, how she responded to it! "You need a hard cock fucking this naughty cunt! Not just any cock, either, though you'd give it up to anybody who wanted it wouldn't you, slut?"

That thought was disturbingly hot. Amelia riding some stranger's dick while Alex fucked her mouth. Her mounting Alex and him holding her close as yet another man entered her tight virgin ass. Fuck! "God damn, take that cock, you fucking harlot! Yes!" He was slamming her, her tits bouncing with each rough, hard thrust. "You love big brother's cock, don't you? You want your brother's hard, long, thick dick destroying this pussy every day! You fucking can't live without it, can you?"
 
Her moans grew louder, and Amelia's back arched as Alex plowed her pussy open over and over. "I can't! I fucking lived too long without it already!" Her lower lip caught between her teeth as she groaned again. "This sweet brother-cock! I love it! I'm a slut for it!"

It felt like her cock was going to explode, and she gave up holding onto the couch cushions for stroking her shaft with one hand and teasing the breasts that bounced with every incredible thrust with the other. "Yes! Alex! See how hard my cock is or you? How fucking hot and wet and hard you get me?"

She pushed herself back down onto his dick, matching his rhythm with her movements - and the stroking on her cock. If she hadn't just blown her load - inside of his ass, a little voice reminded her, giving her a shiver - she'd be done by now. It was just too good. "Fuck! Alex, I love feeling my tight cunt spread by that hard, wonderful meat!"
 
"You horny bitch!" Alex grinned savagely, fierce eyes feasting on the sight of his sister being fucked by his cock, of her stroking her own member, playing with her tits as he nailed her. "Pinching your nipples, rubbing your cock, you're such a damn, naughty, nasty little whore! Big brother's fucking cock slut!"

God, this was so insane. This was perverse madness, and he fucking loved it! She felt so good! So good around his cock it shouldn't be possible! "Love the tight of this slut pussy on my cock. Big brother LOVES fucking his baby sister's sweet cunt, wants to fucking pound your hole all the time!"

He tightened his grip on her hips, roughly pulling her back as he fucked into her as hard as he could. "God, YES! Big brother's going to fuck your sweet ass, this whore pussy, and that hot little mouth every chance he gets! Use each and every one of your fuck holes, little sis!"

God, he was going to cum. Shit. Shit, shit, SHIT! "AH! You hot bitch! Big brother's about to cum in your pussy, baby! God...damn! Amelia! Take...ahhh, take all of big brother's jizz!" His rhythm broke as his internal pressure did, Alex still thrusting as his cock swelled and spurted his cum into her hot, wet, slick insides. He howled out his pleasure; continuing to move as the think, heavy jizz pumped into her belly.

He fell atop her, panting. "...fucking hell, sis...never felt...so weak but so strong."
 
As he started his orgasm, Amelia groaned. "Yes, Alex! Please! Love feeling you full me with cum!" And with that, her own cock let loose, coating her stomach and chest in sticky white cum. "Fuuuuuuuuck! Yes, I'll take all you have, big brother!" Feeling him pumping her full of his seed was the best thing she could remember, the hot, heavy feel of a load of cum inside of her . . . and knowing that he truly loved her, because he was her brother, made it even better.

When he collapsed on top of her, Amelia wrapped her arms around him, kissing his forehead gently. "It's . . . wonderful, Alex . . . sex with you is so . . . just . . . wonderful." She laughed weakly. "I can't think of any other word, really. You're just . . . you make me feel like I can fly."

Amelia stroked his hair, smiling up at him. "So, big brother, what should we do the rest of the day? After we've cleaned up, of course."
 
Alex kissed his lovely sister deeply. This was good, and it felt right. Like in having sex, they were finally truly able to express their feelings. He loved her and she loved him. It wasn't like they'd ever have to doubt it or worry about. She was his sister, he knew she loved him. It was perfect.

As long as he didn't think about the details. But even that, he was sure they could deal with. Whenever it came up.

"After we clean up...I'd love to get dirty again," he grinned. He sighed then, "But we're going to have to go back to school eventually, so we should probably do our make up work." He lifted off of her, then groaned as he pulled out of her pussy. He stared at her sex a moment, cum oozing out of her and a thought struck him. "Shit."

"Holy fuck, I didn't even think about it." Alex took a few steps back, leaning against the wall, his eyes wide and stricken. "Amelia, this whole time...we haven't used any birth control." Disease wasn't an issue, but pregnancy...that...they just couldn't let that happen. Not now. "Damn it, I can't believe I've been so careless about you! Your safety! What the hell was I thinking?"

He shook his head. Damn him to hell! "We need to go to the doctor, today. So that we can get your protected and to see if..." All it took was once. How many times had he cum in her? Fuck. He swallowed, looking a bit green. "I'm sorry, sis, I...should have looked out for you better." Instead of doing that, he'd gotten carried away screwing her. Some big brother. "...we should get cleaned up and do that, as soon as we can."
 
She blinked, then blushed. "Oh, wow. You're right, Alex! I can't believe I forgot about . . . man." Amelia shook her head, crossing her legs. "We really do need to get to one of the ship's doctors." Standing up, holding her legs tightly together, Amelia brushed a hair off her face. "When I'm done, I'll check a calendar. I think we're all right, but my count of days may be off."

She made her way to the bathroom, stroking his cheek in passing. "It'll be all right, Alex. We'll get it taken care of." Amelia scrubbed herself in the shower, and made sure to get as much of his cum out of her as she could - though it bothered her, getting rid of Alex's . . . not the point. the more she got out, the less there was to worry about. Wrapping a towel around herself, she walked back to her room, dressing quickly in what she thought of as her 'comfort clothes': a long, soft skirt, a tank top with a bra attached, and a long cardigan sweater.

Then she went down the hallway again, knocking on Alex's door. "Big brother, I'm ready when you are." She poked her head around the door, smiling at him as he sat on his bed. "I think we'll be able to get this taken care of pretty easily."
 
Alex looked up, a faint smile crossing his paler than usual features. She was showing very good cheer considering what could have happened. Hell, what could BE happening for all they knew. Damn him! He should have thought about her. The smile fell. "Yeah, I'm sure you're right."

What if she wasn't? What if...

He finished tying her shoes and stood up. He was wearing loose slacks and a slate blue t-shirt tucked into his pants. He walked up to Amelia, giving her a hug. "You look good, sis." She felt good too, in his arms. He gave her a squeeze, "Well, let's go then."

God, let her be all right.

"Come on in, you two." Nurse T'gril smiled at the two young humans who had been patiently waiting. Not that they'd been waiting long. It was a very slow day, thankfully, and given this family's unique genetic structure, they were considered a priority. "You're both looking good. Ah, well, I mean." Great Mother, had it really been that long that she was ogling patients?

T'gril was a bit short by human standards, most of her people were. She stood fully five feet tall and her body had a slender and gracile structure though there was no doubt looking at her that she was a female. She seemed to have been poured into the white catsuit-like nurse's uniform, the fastening undone just enough to show the hints of her ample cleavage. Two of her four arms flpped through a paper copy of Amelia's file, one of the others beckoning the kids to follow her back into one of the privacy shielded exam rooms. Her pert ass swung from side to side, the motion accompanied by the swing of her long, thin, prehensile tail. She was covered in a very thin, very fine coat of reddish fur, her head adorned with glossy black locks that were currently pulled up into a high ponytail.

She closed the door behind the twins, indicating Amelia to have a seat on the table in the middle of the room. "All right then. What can I help you two with? I'm sure this isn't a social call, sadly."

Amelia hopped up onto the exam table, her hands braced on the edge of the table. "Well, you're right." She crossed her legs at the ankles. "See, I . . . need to get on some sort of birth control." Her eyes went to her lap, her legs shifting slightly. "Alex came with me, because our parents are out on a mission."

"Mmmm." T'gril nodded, looking at both of them. She didn't really believe it for a minute, but it would be interesting to see what kind of lies they'd come up with. "What makes you think you need birth control?"

"I've, um," Amelia bit her lower lip, "I've been having some trouble with acne, and I know that it sometimes helps with that." She felt her face heating as the nurse sauntered close, one of her hands lifting Amelia's chin.

After a moment's study, T'gril's lips curved, showing slightly pointed teeth. "Your skin looks lovely to me, Amelia. Very smooth." The other hand on that side of her body reached out and placed the file on a nearby table. "So, why do you really want it?"

"My period's been really painful - I left class the other day, during the approach to the nebula - because I wasn't feeling well." Amelia's face was more composed, in part because this was only half a lie. She really hoped the nurse would believe it, that she wouldn't have to tell her what was really going on.

"That's another good one." T'gril sighed. "But, just in case you're not lying about this, lie back on the table." Two of her hands grabbed gloves and slipped them on the other two. "No matter what, I'd have to give you an exam first."

Amelia leaned back, putting her feet in the stirrups. "Okay." This was always the worst part of any exam. And with their genetics, and the associated physical manifestations, every exam involved a pelvic. It wasn't comfortable, but this was something they needed. As the nurse started the exam, Amelia looked up at the ceiling of the room, trying to think of anything else.
 
Alex stood in the back of the room, trying not to think about how Amelia's gorgeous genitals must look in those stirrups, so well displayed and there for the taking...Good God, he was a pervert. It didn't help to think of the luscious Nurse T'gril being down there and doing...things either. His mind provided him a few images that only made matters worse.

T'gril stood up, removing the gloves. "Thank you, Amelia, you're done." While one of her hands disposed of the gloves, two others picked up Amelia's file, flipped to a page and began to write a few things. The last one helped the girl out of the stirrups. "I did notice something unusual." The alien nurse smiled a bit, seeing apprehension of both teen's faces. Oh, they were so cute and so easy to read. "I do think you should have birth control, and we have several options you can use. With all the sex you've been having, you really should have come to me sooner."

Their faces drained of color, and T'gril fought hard to not smile. "Especially since you and your brother are so close, I expected him to be more careful about your health when he sleeps with you, Amelia."

Alex stepped up next to his sister, who looked like she might faint. "Nurse T'gril, it's not, that isn't what's happening."

The red furred woman arched her eyebrows, "No? Then all of that semen I found with your DNA must have gotten into her vagina by accident."

Alex blushed bright red, then paled again. "T'gril, I, you...you can't have found that. If you do, and you report it, they'll...they'll seperate us, lock us up, you can't..."

She smiled then, reaching out to stroke the cheeks of both young people. "Shh. It's all right. I do need to report that Amelia is sexually active, and that's her reason for birth control, but that's for her records only. Only she, and me, and her doctor will see it. And I certainly do not need to put who she's having it with down." She smiled and sighed, "It's very sweet, you two are so very cute together, and both so lovely..."

Alex blinked. What...just happened? "Wait, you're...why aren't you freaked out?"

T'gril laughed, "You humans and your sex taboos. I forgot." She shrugged, her breasts swelling, "Among my people, incest is accepted. It's a way to show your family how much you care. My first time was with my father. And I made my little brother into a man." She shook her head, "From my point of view, this is natural, even good."

She sighed again then, a bit deeply. "I'm actually jealous. I miss my family so much, it's been so long since...well, you don't need to hear about that. Let's get you set up, Amelia, dear, and then you and your handsome brother can enjoy each other to your heart's content."

Amelia sighed a little, relieved. She had hoped they wouldn't be in trouble for this, and they weren't. But there was also a hint of regret - the nurse seemed so sad over missing her family that it touched her. "Okay, thank you," she said softly, sitting up on the table, one leg kicking back and forth. "I'm sorry you miss your family, T'gril. I don't know what I would do if I had to leave Alex now."

The red-furred woman smiled and shrugged. "I have come to terms with it - and it makes the times when I am home that much more special." She walked over to one of the many cabinets in the room and opened it, bending over to rummage around inside of it. Amelia noted the shape of her ass with no little interest, and glanced at Alex to see him doing the same. She snickered a little, and grinned at him as he looked up at her and blushed.

"I'm sure that your family misses you a lot, though," Amelia said, her eyes travelling over the alien woman's form as she shifted in her search for whatever she was looking for. "I mean, you're lovely, and I can't imagine how much your family must enjoy being . . . being around you."

The nurse stood up and turned with a smile, her two of her hands carrying a small tube. One was red, the other blue. "Thank you, Amelia. They tell me every time I visit them how much they miss me, but it is still nice to hear that others appreciate my . . . rather unique look, even here." She held out the red tube to Amelia and walked the other one to Alex. "There you go!"

Amelia looked at it with slight surprise. "This is the birth control? And Alex gets one too?"

T'gril grinned at them. "This is a special birth control - a lot of the usual ones won't work for people with your condition. And yes, Alex gets one too." She lifted the tube from Amelia's hand, turning it over. "These are both topical birth controls. One gets massaged onto your private areas, Amelia - that's the red one - and one gets massaged onto Alex's." She grinned. "As you may have guessed, that's the blue."

"Huh? You mean," Amelia blushed a little. "You mean we'll have to rub these on our . . . wait, on which part of mine?"

"Well, since what we're mostly concerned about is your getting pregnant, it should be applied to your labia and the entrance to your vagina." Amelia's face was still a little confused, so T'gril sighed and twisted the cap off the tube. "Here, I'll show you. Lay back." As Amelia leaned back on the table, T'gril motioned to Alex. "I'm sure you'll want to do this for her sometimes. And if you want, I can show Amelia how to help you apply yours."
 
Alex wasn't sure there was anything stranger than what he was doing right now. The youth nodded at the alien nurse's instruction, walking over to stand next to her. He looked down, swallowing as he saw the woman put Amelia's legs in the stirrups of the exam table and then push up his sister's skirt to reveal her panty-clad privates. He felt like he should say something...but he didn't know what.

"Now, then." One of T'gril's sets of hands pulled Amelia's panties down past her knees, the other holding the vial and scooping out two fingers full of the red stuff within. It was a viscous liquid, clinging to her furry fingers. "As I said, this is applied topically, to the labia and vaginal entrance in females and to the scrotum and the glans. Though you can rub down the whole thing in either case, it won't hurt."

The lovely alien woman ran her two goop covered fingers down Amelia's slit, one on each side of it. "Just brush it on and gently rub it in." The finger moved up and came down again, and again, and again, over and over, rubbing over the mutant girl's sensitive area. Amelia squirmed in the stirrups, obviously trying not to react to the sensation. "Nice, isn't it? It's got a warming agent in it...no cold lotion for your pretty, ah, I mean, for such a sensitive region." T'gril shook her head. Had it really been that long? ...It had. If only things were different...

Alex shifted, his cock swelling in his pants. He knew the signs of Amelia's arousal. As the nurse's skilled hands applied another two fingers of the cream, this time to the inner side of Amelia's labia, he licked his lips. God...this was...why was this so fucking hot?

T'gril nodded. "Good. Remember, do it like that. Two layers on each side, fully rubbed in." She glanced up at Alex, "Did you get that?" He nodded numbly, and she smiled. Oh, they were horny young things weren't they? Her eyes flicked down and she blinked to see the bulge in his trousers. More than she expected. "...You know, we should do this more efficiently." She patted the table beside Amelia, "Alex."

He started, "Y-yes, ma'am?"

She grinned. "Trousers and underwear off and hop up here. I'll show you both at the same time." And get to play with them both as well. Her other set of hands was unscrewing the lid of the blue contraceptive as Alex hastened to obey.

He got up onto the table beside Amelia, both his sister and T'gril able to see his still growing erection. He blushed, one of his hands taking hold of his sister's. "Uh, sorry, it's just..."

"It's all right," T'girl purred, eyeing his cock. Mmm. "It's a natural response and helpful. You see, these go on much easier with a hard member...and a wet vagina. It aids absorption." She was trying not to smile. Work had never been this much fun! Two of her hands came up; on one two fingers holding a large dollop of the red, on the other, the blue. "Now, for Amelia's internal treatment...insert the fingers with the preventative up, to about the first knuckle." As she spoke she performed the action. Gods! Such a tight, hot little cunt! "Then press up gently and rotate your hand around as far as you can."

The hand with the blue went over to Alex, "For the male, you want to massage about this much into the glans. The head of his phallus." Alex couldn't help but groan as her fingers enclosed the head, swirling and rubbing it. T'girl smiled again, "One side effect of this treatment is, of course, an aroused state. Fortunately, it takes effect almost immediately upon application."
 
Amelia grinned as Alex moaned softly, the sight of his cock being stroked by the nurse's red, furred hand. "Big brother likes having the nurse treat him . . . ahh!" The alien woman smirked as she pulled her finger out of Amelia's pussy again. "I like it too," she breathed, licking her lips.

T'gril chuckled softly to herself, her hands moving a little faster. "I'm glad you two are so responsive. Makes my job that much nicer . . . easier." One of her free hands stroked Alex's thigh, while the other free hand set the two tubes of contraceptive on the table behind her and moved to stroke over Amelia's bare stomach.

Amelia shivered at the feel of the hand stroking her skin, her hips shifting a little, pushing her more firmly onto T'gril's fingers. "Ohh, Alex, I think I'll like you helping me with this," she murmured, squeezing his hand. "T'gril, it feels so . . . very good. Your hand is very skilled," she managed, feeling her own shaft rising. "Gods, your hands are amazing."

The hand that had been stroking the skin on her stomach slipped downward until it grasped the shaft, pointed white teeth catching the nurse's lower lip. "Thank you, Amelia," she said softly as she started to stroke the siblings in tandem. "You and your brother are both very . . . good subjects." Her tongue slipped out, moistening her lips. "And both so big," she whispered, almost inaudibly.
 
Alex looked over at Amelia and smiled eagerly. He could see the emotions warring on her lovely face. Desire and lust fighting with propriety and fear. He knew that T'gril's skilled hands and scorching body were turning her on just as much as him. He knew she'd thought of fucking the nurse just as much as he had. But what do to about it?

He gave Amelia's hand a squeeze, leaning in to whisper in her ear, "Follow my lead, sis." Then he leaned back and got himself up on his elbows to get a better look at what the medical assistant's hands were doing, as well as the look on her face. It could be hard to tell with aliens but she seemed almost engrossed in what she was doing. Her magnificent chest was rising and falling noticeably.

The teen cleared his throat, "She's right, your hands are amazing." He licked his lips, this was the risky part. "But the treatment's over, isn't it?"

The nurse looked a bit stricken and nodded, her hands staying where they were but ceasing their motion. Amelia whimpered. "Yes, I should...stop."

"But you don't want to," Alex said hastily. Her green eyes turned on him and saw in them the same warring feelings that were in Amelia's. "You don't have to. We like it. We like it a lot, in case you couldn't tell."

T'gril looked again at the twin's hard cocks and at Amelia's wet pussy. She licked her lips. "I can tell. Both so...quickly aroused and so well shaped..."

"You are too, T'gril," he went on, low and warm. "You're just as aroused as we are, aren't you?"

"...yes," she said in a quiet voice.

"And you are gorgeous, T'gril. Your body is amazing. Sun level hot."

She smiled a bit, "I'm proud of it, but-"

"Show us." Alex grinned. If this worked, they'd have her the rest of the way too. "We've shown you ours. And I know it's been a long time since you got to have anyone appreciate and see the sexy body you work so hard to keep up." He sat up, looking down at the kneeling woman. He pulled his shirt off, baring himself completely. "Let us see you."
 
Amelia liked where her brother was taking this. So she sat up as well, taking off her sweater and pulling the tank top she wore over her head. "Please, T'gril? We want to see your beautiful body."

The nurse hesitated for a moment. "But I . . . it was for the treatment, and . . ." her hands twitched, and she shifted slightly. The resolve to be professional was withering, and . . . hell, it had been gone the minute she put her hand on Amelia's cock. Her one free hand moved to the zipper holding her suit shut, slowly pulling it down.

Amelia's breath caught in her throat as the alien nurse's deep red body was slowly exposed. Her large breasts were pushing the material open, spreading it open almost to expose her hard nipples. "Oh, T'gril," Amelia breathed, feeling her cock twitch in the nurse's warm grip. The zipper finally reached its terminus, below T'gril's navel, but just above where the light fur of her body gave way to thicker pubic fur.

Amelia put her own hand on her cock, and then took her hand out of Alex's and began to stroke his cock as well. "Take it off, T'gril. We're both so hot and hard from your touch and your body, I can hardly wait to see it all."

T'gril took her hands back, shrugging out of the bodysuit, peeling it off her luscious body like a second skin. As the suit hit the floor, her hands were back on the two hard cocks in front of her, stroking eagerly, this time for pleasure. "You are both so . . . hot, such young, amazing bodies," she whispered.

"Mmmmm, your body is . . . is amazing as well," Amelia managed, reaching out to caress the nurse's body, her fingertips just brushing the lightly furred side. "Don't you agree, Alex?" his sister teased, knowing full well what the answer was.
 
Alex gasped, his breath hissing out of between his teeth as the lush alien nurse began to stroke him again, "Yuh, yes, God, yes." Fuck! He'd never felt this good from just a hand. Not even Amelia's hand. "So sexy and ripe, I've, unnn, noticed before, but never hoped..."

"Oh?" The red furred woman smiled, "Have you lusted after me, young Alex?" He nodded and her smile widened. "How very flattering. I lust for you too now, and your gorgeous little sister..."

Alex sat up slowly; shifting his ass back a bit to keep his balance. "Since we're all lusting, we should take care of that, right?" He leaned forward, one hand moving to cup a large, soft, red breast as his head dipped to kiss the base of the left side of her neck.

"That would, ahh, be my prescription, yes," she answered throatily. Her hands continued to stroke and fondle the twins' cocks, the third looping over Alex's shoulders and pressing him against her, the fourth slipping low and starting to tease Amelia's pussy with her fingertips.
 
Amelia began to whimper softly at the feel of the nurse's clever fingers toying with her cunt. "Oh, fuck," she whispered. "Feels so good, your hands on my cock and pussy!" Amelia leaned forward, one hand wrapping around T'gril's hips as she put her head to the round, full breast closest to her, lips closing around the hard nub of the red nipple.

The alien nurse moaned softly, her hands rubbing and squeezing each of the twins unconsciously as she felt Amelia begin to suck on her chest. "You two . . . are very skilled at this, feel soooo gooooood," she cooed as Alex's teeth scraped across the skin of her neck. "It's been a long time since I've been with two at once," she managed, one finger slipping inside of Amelia's pussy and stroking gently in and out.

The younger girl gasped at the feeling, her legs spreading wider to let the pretty alien's hand finger her with greater ease. "You're handling both of us well," she panted as she pulled away from the hot flesh in front of her. She'd never . . . been with a woman before, and Amelia was sorry she'd never tried before this. It was hot, feeling another woman's breasts, tasting her skin, feeling a small, soft hand on her shaft . . . god, it felt amazing!
 
Alex was astounded. Part of him just couldn't believe what was happening right in front of him, to him. Much less that he'd actually started the ball rolling. As his pretty little sister started to suckle on T'gril's large, luscious tit, he let out a low groan, "That is...one of the hottest things I've ever seen."

"For me too," T'gril answered. "Oh, her mouth is so good." She looked down at the human boy. "...Want to taste, Alex?" The hand that had been stroking his back came around to heft the breast he'd been fondling. "You can, it's okay."

He swallowed, licking his lips, and then leaned in. His pink tongue encircled the slightly rough textured skin of her aureole, drawing a chuckling whimper from the red-furred alien beauty. Then he pressed his face to her tit, opening to take her nipple between his lips. Lashing his tongue over the tip, he started to suck gently, moaning into her flesh.

"Oh, kids, that's just...wonderful," the nurse cooed. Her hands continued to pump and play with the twin's cocks; switching to rub the pre-cum of one over the shaft of the other. Her lower right hand slipped another finger into Amelia's now sopping cunt; pumping them in and out slowly while her thumb teased the girl's pearl. "You can, ahh, think of me as...oh, shit, as your big sister. Big Sister will take care of youuu, if...if you're good kids."
