The jealous sister(closed)

Oh man she could imagine his cock popping out of his boxer and made a soft little moaning sound which she hoped mixed in with the movie they were watching..,or not watching. She tucked her hair behind her ear as her nipples hardened with the idea of his big thick cock.

“I was joking.” She said calmly,”but if you weren’t scared of my sister, I totally would.” Allie reached for her drink.”but not the hardcore stuff, just one of the costumes. It’s not like I’d rat you out or anything, “ men liked challenges didn’t they? “You look like a naughty school girl kind of guy but I mean you’re scared. So it’s fine. Let’s just go back to watching the movie.”
 
Matt kept finding his eyes drawn to Allie’s big tits. He was spending more time looking at them then he was the television. “Scared?!” Matt said downing the rest of his drink and setting the empty glass on the table. “I’m not scared of your sister! Go put that costume on then, it sounds like you really want to try it on.”
 
It took everything in Allie not to giggle in delight. “If you say so, just remember you asked me to do it.” She said in a song song voice before running up the stairs into her bedroom. She began going through all her sexy costumes and grinned.

Allie had two different costumes, the super slutty school girl and the slutty school girl. She didn’t think Matt was ready for the super slutty school girl, so she shimmied into the red skirt and pulled off her bra, then tied the white blouse on. Allie put on the matching red heels on and then reapplied her shiny lip gloss.

She pushed her auburn hair behind her shoulders grinning at how the tied blouse accentuated how big her boobs were then walked down stairs and twirled for Matt before sitting down next to him again.

“I look smokin right?”
 
When Allie disappeared to her room to put the outfit on Matt had a slight feeling of guilt doing this behind Tiffany’s back. Then he thought about how they weren’t really doing anything wrong, I mean they probably shouldn’t be watching porn together but she is just trying something on, no harm in that right? Matt took another sip of his drink then relaxed back into the couch very drunk right now.

He closed his eyes for a moment then when he heard Allie coming back down the stairs he opened them back up and liked what he saw. First thing he noticed were Allie’s big breasts bouncing in the tied white blouse that barely contained her big tits. Then when she spun around her short skirt lifted in the air and he saw her big juicy ass before she sat down on the couch. “Wow...you look amazing. I really like that outfit.” He said not able to take his eyes off of Allie.
 
Allie grinned at him as she made herself comfortable on the couch. The moans of the video filled the room and if anyone were to step inside at this moment, just by the sounds of the porn they’d make automatic assumptions about what was really going on. Though Allie had to admit there would be some of that action going on.

“Thank you, I’m glad you approve.” She noted that he was staring at her breasts but trying desperately to make it not like he was trying to look at them. He was still apprehensive, even if he’d challenged her to change clothes. “I dunno though, my last boyfriend didn’t like this costume much.”
 
“I’m sorry what?” Matt almost sounded shocked when she said her last boyfriend didn’t like that outfit. “Was he not into girls? Because that outfit looks so fucking good on you.” He said as his eyes traveled from her big breasts and smoke cleavage down to her short skirt and her creamy thighs that were on display.
 
Allie grinned at him but shrugged slowly. "I don't know, I always just figured my boobs were too big or something." She looked over at Matt with a pout before glancing down at her massive boobs that were threatening to pop out of her tied blouse.

"Are they? I mean, I don't think my ex was much of a boob man anyways, but you seem like one. Are they TOO big? I mean, I'm probably like a freak right? I mean sure they're great for like playing with and tittyfucking but this isn't actually what a guy wants is it?"

As she talked she played with the tie twiddling her fingers with it, it slowly started to loosen but hadn't completely.
 
As Matt listened to Allison talk he kept thinking about how shitty her ex must have been to fill her head with these ideas. “Freak?” Matt looked at Allison as he talked. “You are not a freak.” He then let his eyes wander to her big breasts. “They are not too big. As a matter a fact they look perfect.” His drunken mind began to blurt our words without thinking.

“Of course a guy wants those things! Well a straight guy at least.” His mind filling with images of Allison tittyfucking his big dick. I love getting titty fucked and having big tits in my face while a girl rides me.” He was picturing Allison doing this to him. “Asking if a guy likes big tits is like asking if a girl likes a big dick on a guy. Of course they do right?”
 
"I-I'm not..." Allie said, faking a nervous stammer. "I mean I do wonder sometimes. " Her nipples were slightly hard from the long hard stare he was giving her breasts and as he described what he liked to do with big breasts. She moaned softly, she was pretty sure that they were forgetting about the movie that was on right now.

"Yeah? Is that what you like? I mean, not all girls like big dicks though. They're the weirdos in my opnion. I kind of always imagined that ...yours was pretty big. Would I be disappointed?" She scooted closer to him so that her breasts rubbed against his arm whenever he moved around.

"We should totally play a game. Truth or dare? I know it's childish but....if it gets too cheesy, we can up the ante..." her finger lightly grazed his strong bicep.
 
Matt was forgetting all about the movie since he had this very sexy girl in front of him to look at. His drunken mind forgetting all about his girlfriend and thinking more about the perfect tits on display for him right now. Matt chuckled softly when Allison asked if she’d be disappointed. “Not at all.” He winked then added another drunken chuckle.

“Truth or dare?” He made it seem like he wasn’t interested in playing just to mess with Allison. “That game is super childish...” he paused for a moment then continued. “...just kidding. Yeah I’m down. You start.”
 
God, he was sooo drunk, it was absolutely perfect. For a minute, he'd been so into thinking about her older sister that Allie didn't even think she would get this far with him. Part of her wondered if when he got sober would he be this easy to manipulate. That would defintely be a challenge worth going for but first, she had to infiltrate his drunken stupor so he wouldn't be so hard to deal with when sober.

"Eeek! This is going to be soo fun. Okay, before I start lets establish some rules. To make it less 'childish' if you don't answer a truth question, you have to do a dare of course and take a shot and if you don't do a dare you have to take a piece of clothing off. If all the clothes are gone then you have to do whatever person asks you to do like if I dare you to run around the neighborhood streaking in the cold, you do that or anything I ask like if i said if you don't do that then you have to suck on my big tits for 10 minutes. Then you have to do that because you didn't do the dare. Deal? "

When he agreed, she smiled, "Now let's see...truth or dare Matt?"
 
Matt listened to Allison explaining the rules of the game. When she mentioned the last part he just pictured him sucking on her big tits for ten minutes. Her smothering him with her big breasts while he sucked her nipples and left hickies all over her tits. Her grinding against his bulge that was about to rip through his pants.

“That is definitely less childish alright.” He said with a chuckle. “Hmmmm truth.”
 
"Chicken..." she teased then tapped her chin.

What could she ask him? She could ask him if he wanted to fuck her but that would be too easy, wouldn't it?

"If you could live any sexual fantasy, what would it be and with who?"
 
Matt didn’t want to come right out and say he currently wanted to fuck Allison’s brains out so he thought of something else he always wanted. “Hmmmm I’ve always wanted to have a threesome with two girls.” He rubbed the back of his head. “I doubt your sister would ever be interested in that so with any two girls who would be into that.”
 
Allie felt slightly disappointed because he hadn't said he wanted to do anything with her BUT, he did insinuate that because her sister would most likely be against it, that he'd do it with any other two girls. Close enough. She bit her lip and grinned,"I've never had a threesome with another girl before, I've had two dicks though. It's probably really fun though."

Oh she wanted him to imagine her with another girl. She wanted to fill his mind with fucking her in any way he could so that was all he'd ever want to do. She wanted him to be almost obsessed with fucking her.

"My turn right? I mean your turn to give me a truth or dare. I won't be a chicken, dare. Give me your best, Matty."
 
It sure sounded like Allison would be interested in having a threesome with him and another girl. Matt grinned thinking about how sexy it would be. Then he started to think about what dare to give her. Since she mentioned it earlier he has been thinking about what other possibly naughty outfits she had. “I dare you to go change into your favorite naughty outfit you have.” He was curious as to if she was bluffing about having other costumes or not.
 
Allie grinned, "I'll be right back..." her voice was husky and full of lust. She jumped off the couch and ran upstairs into her bedroom. She tore through her closet trying to decide what her favorite costume was. She once dated a batman nerd and he got off on her dressing up as the sexier version of Harley Quinn.

She pulled it out and put it on. It was a black and red corset like top and short skirt. It also came with a black mask. She tied her red hair up in pigtails and ran back downstairs, because her breasts were so big it seemed like if she moved too suddenly, they would would pop out at any minute. They were secured in her corset vest but it still seemed that way and if need be, she could always pretend that they did.

"What do you think?"
 
Matt wondered what she would come back dressed as. When she came back dressed as Harley Quinn he grinned wickedly and had to resist the strong urge to fuck her right there. His favorite naughty outfit was Harley Quinn. It turned him in so much. His eyes watching her big tits nearly pop out her top. “Oh my god Allison.... that outfit is so hot! You make a sexy Harley Quinn.” His eyes glued to her body. “I pick dare.” He said before she could even ask.
 
“Dare, huh?” Allison looked thoughtful for a minutes pursing her lips together tightly.she tapped her chin thoughtfully ignoring his gaze on her breasts. “I dare you ....” she snapped her fingers. “I dare you to let me lick your lips but you can’t kiss me.”

Was he drunk enough to let her do that?

Just in case he wasn’t.

“If you don’t want to though, you can always take a piece of clothing off.” Allie shrugged her shoulders as she stared at his lips waiting for his answer. Just the idea of either option had her squirming on the couch in excitement.
 
Matt’s eyes were still glued to Allie’s body as he ogled her sexy outfit. His daze was snapped when he heard what his dare was. He rubbed his chin while he debated between his two options. “Hmmm. Well I mean if I can’t kiss you then technically it isn’t a kiss so we wouldn’t be doing anything wrong.” He thought out loud while looking at Allie. “Okay Harley.” He said looking at her outfit. “I pick the first option.”
 
Oh but Matt everything we’re doing is wrong right now. Allison thought to herself before climbing on top of him, straddling him. “Sorry, I have to be at a good angle to do this.” She was totally lying but smiled innocently to cover it. Allison started her timer on her phone for 5 minutes then set the phone on the table. She leaned forward her breasts brushing against his shirt.

Lightly she brushed her tongue over his lips. She started with his top lip then his bottom the brushed in between them almost enticing him to kiss her. Her hands held onto his strong shoulders.
 
“Yeah good angle, makes sense.” Matt said settling back into the couch as Allie straddled him. She sat right on his huge erection sandwiching it between him and her pussy. “Five minutes?!” Matt almost protested but the she started licking his lips. Her warm moist tongue running along his lips felt really nice. It took everything he had not to kiss her. When her tongue was on his top lip he licked his bottom lip to taste her sweet saliva. His cock only grew harder as he tasted her saliva. His hands gripping the couch cushions wanting to be grabbing her ass instead.
 
She felt his tongue brush along hers when he licked his bottom lip and his cock press against her pussy. He was so fucking hard right now. “You can handle it.” She said pulling away from his lips for half a second.” After all we’ve had porn going all night and you haven’t even tried to fuck me. “ her hands brushed down his chest before glancing at her watch. 3 minutes and counting.

She brushed her tongue along his lips again. She was getting wetter and wetter and out of the corner of her eye she saw him clench the pillows. She reached for his hands and pulled them on her ass. He got about one minute of groping her ass before the timer on her phone went off.

“Dare.” She mumbled against his lips before pulling back. God, she wanted him so bad right now, she’d probably do anything.
 
To Matt this torturous teasing seemed more erotic then actually kissing. Her wet tongue coating his lips in her saliva. Every once in a while their tongues would brush together making it even harder to resist kissing her. ‘Three more minutes... you can do this.’ Matt thought to himself after Allison told him how much time was left. When she grabbed his hands and put them on her ass under the short skirt on her Harley Quinn costume he started squeezing and caressing her big full ass. His monster cock throbbing beneath her.

After the timer went off Matt licked his lips clean of her saliva loving her taste. “That was really hard to not kiss you. Just saying.” Matt sat in silence after speaking with Allison still sitting on his lap for a few moments thinking of a dare for her. “I dare you to put any part of your body against my lips and I’ll close my eyes and try to guess what it is.” He said with his hands still squeezing her lucious ass.

Jesus, Allison was so horny it was disappointing when her timer went off. She probably could’ve cum right then and there if they’d gone on a bit longer. At his dare, she licked her lips and nodded her head. The only issue was she wasn’t sure which body part needed relief.

All of her did, to be quite honest. She waited for Matt to close his eyes and she undid her Harley top letting it fall to the ground and pressed her breast up to his mouth. She knew it would be easy to taste but it gave way to her next date if he chose that option. She moaned as he began sucking it her back arching. “Fuck.” She whispered,”c-can you guess, Matty?” She asked as she smothered his face in her big breasts.
