Name: Cassidy Kline
Age: 18

Since she could remember, Cassidy (who was 6 years younger) wanted to be just like her older sister Lynn. Lynn had it all, beauty, brains, confidence...

There was never a time Cassidy hated Lynn for anything. She relished the hand me down clothes Lynn had given her. She was sad when Lynn left for college but they kept in constant contact of course. When it was finally time for Cassidy to go to college, Lynn let her stay with her and her new husband Mark.

Both Lynn and her new husband, Mark Reed, had been married just over 3 months and had moved into a new home. H was happy to help out by letting Cassidy stay with them, granted she did her part around the house...

Needless to say, not knowing how to explain it, Cassidy had a small crush on Mark...

Mark was eager to let Cassidy stay for a while, since he worked hard hours running his carpentry business and Lynn had just started working for a new firm, neither of them had much time for house cleaning. An even bigger bonus was the fact that she cleaned the pool on most afternoons so it was ready when he came home. His daily routine was the same throughout the hot summer, after a quick shower to wash off the day's dirt, he went for refreshing dip in the pool.

He also liked the additional company since he always arrived home 2 hours earlier than his wife thanks to her long commute to the city. This arrangement seemed to be working out much better than he originally anticipated.

After Cassidy was settled in he started learning a lot more about his new sister-in-law.

Cassidy had just finished with the pool. She was wearing a pair of shorts and a bikini top, her iPod blasting away as she put the cleaning tools away. She noticed Mark came home early and she gave him a wave as he headed to the pool.

Her next class today was not until later tonight...so there wasn't much to do except laze around and catch some rays of course..but she had a feeling it was too late in the day for that.

Oh well...maybe talk to Mark for a bit, get to know her brother-in-law a little more.

Just as he jumped into the pool, Cassidy sat down at the edge and let her feet and legs dangle in the cool water. She watched him do a couple of laps until he finally stopped. She smiled and called, "Looking good Mark!"
 
"Thanks, you too! The pool looks great by the way. I may have to actually start paying you if you keep this up." He swims over and nervously talks with her. Her legs are slightly parted and he has to force himself not to look at her young ripe lips that are slightly visible through the loose shorts. "Did she know her shorts were offering him a view of her pussy? And why isn't she wearing underwear or bikini bottoms?" Mark wondered to himself. He was affraid that she would see his eyes peeking up her shorts and get offended. It was all he could do to keep looking her straight in the eye. This wouldn't be as difficult if she would stop slowly stroking her leg.

Not wanting her to see his emerging erection, he asks if she could grab some cold drinks from inside. Exiting the pool he grabs his towel and quickly unfolds it to conceal his excitement, stretching out on the lounge chair he sees Cassidy making her way back from the fridge. She hands him a cold beer and dives into the pool. Swimming from the deep end to the shallow end she walks up the steps and over to where Mark is sitting. "I had to cool off, I'm starting to get pretty hot out here in the sun." She said while picking up Mark's towel from his lap.

Just then he notices he has a new problem. Her large breasts are spilling out from behind the thin pieces of cloth that make up her skimpy bikini top. On top of that her nipples are now erect from the cold water and the material turns out to be very see through when it's wet. "Is she doing this to me on purpose, or is she just clueless about flashing me her pussy and her tits?" His mind is struggling with thoughts of his very sexy sister-in-law and his beautiful wife of three months. "She has got to be oblivious to it, I can't image she would be trying to seduce her sister's husband" Feeling very awkward and worried that Cassidy would discover her brother-in-law is a pervert, he quickly changes the subject. "So are you still dating that guy you brought to the wedding?" That's got to be a safe enough question right?
 
Of course Cassidy had no idea what she was doing to Mark. He was very handsome and of course, when he and Lynn had started dated, everyone had said how lucky Lynn was.

"So are you still dating that guy you brought to the wedding?"

"That guy?" Cassidy asked, as she wrung out her wet hair. "OH!" She giggled and shrugged, "You mean Josh...actually no, he sorta dumped me the day of the wedding..." she shrugged and shielded her eyes from the sun.

"It's no big deal, I knew he was wanting out of the relationship." The truth was, he had fallen big time for one of Lynn's bridesmaid. "I'm going to do another lap to cool off...wanna join me?" She asked, her sincerity was pure.
 
"He dumped YOU?? I can't believe it" Mark replied as he was getting up to follow her to the pool. "You were the hottest bridesmaid there, that guy was obviously insane! Besides, it's a good thing you're rid of him." After the words escaped his mouth he imediately worried that she might pick up on his developing crush on his wife's little sister.

Now he felt his cheeks flush a little and thought it would be the perfect time to dive in. Once in the pool, he was feeling relaxed again. He was wondering what it was about Cassidy that made him feel like an awkward teenage boy again. Maybe it was the fact that her sister was his wife and totally made it taboo, or it was because Cassidy's body was etched in his mind. Whatever the reason, he needed to control himself, if he hits on her will she immediately go running to Lynn? "There's nothing wrong with flirting is there?" Mark asked himself. "Besides, she has definitely been flirting with me."

"So, Cassidy, what are you going to do now that you're single again?"
 
"You really think I was hot?" She asked, her cheeks flushing red.

As odd as it was to hear from her brother-in-law, it was also kinda nice. What girl doesn't like to be called hot?

"I don't know..." she said in answer to his comment about being single, "I guess I'll just concentrate on school...grow into an old maid...who's never had sex..."

"You know, I'm really glad Lynn has someone like you, I like you Mark, it's easy to talk to you."
 
"Um, yeah I did kinda say that out loud didn't I? I meant to only say it in my head. It's true though your body is extremely sexy. That thin silky dress you had on was form fitted to every curve of your body and the way it accentuated your ass was stunning. I actually have a confession to make." Mark couldn't believe he was actually saying this, after downing the rest of his third beer of the afternoon he continued, "remember when everyone was dancing at the reception? There was almost no room to move, well I made an excuse to walk behind you a couple of times on the dance floor and had to squeeze my way past. I actually rubbed up against you a few times and danced there for a few minutes. I had been drinking and couldn't help myself, I thought you noticed and were cool with it." Now his face turned four shades of red but he was emboldened by their honest discussion and wanted to keep exploring the topic. "It wasn't just that time, when you walk around in your bathing suit or when you get out of the shower and walk down the hall I can't take my eyes off of you. You know Cassidy, you are also very easy to talk to. I have to say though, I'm completely shocked you're still a virgin I would have thought the guys would be beating down your door. It's probably a good thing, you want your first time to be with someone who's really gentle and cares a lot about you."
 
"Someone like you..." it was then she realized how that sound, "I-I mean, like how you and Lynn are special..." she was blushing so red and it wasn't because of the sun.

"I guess I'll meet someone like that one day...but I won't hold my breath Mark, men like you are one in a million." Cassidy said, smiling at him.

She hadn't realized how close she'd floated toward him that they were less than an arm length apart...
 
Something was happening within him, yes his erection was growing but there was something else. An intense longing to feel Cassidy's body writhing on his, engulfing him-in her arms and in her moist tightness that has never known the feeling of a man within it. He closed the gap between them so their proximity would make them very uncomfortable if they did anything other than kiss.

"Why not me?" It was all he said, no other words were needed. Nothing else would be adequate to convince her. Just the heaviness of the question and the sexual tension present would be enough. Nick gazed lustfully into Cassidy's eyes while softly touching her arms, he waits before kissing her to see her response.
 
"You?" Cassidy was caught off guard. She looked at Mark for the longest time, the only sound was the water that they were swimming in..the soft splashing...

She didn't know how to react to what he had just suggested. He was his sister's husband!

"I-I..I don't know Mark..." she looked puzzled, confused yet her eyes were full of lust, "What if Lynn finds out?" she asked.
 
Mark started lightly stroking the back of her arms and said in almost a whisper, "Lynn won't find out, it doesn't have to be an ongoing thing. I just really care about you and would love to show you all of the pleasures you can have and teach you whatever you want to learn. I know the first time can be very vulnerable and I don't want you to get hurt." It seems like even time is standing still as he gazes into her eyes, seeing something he hasn't seen in them before: raw desire. Inching even closer, he moves his hands to her lower back and draws Cassidy up against him, feeling her voluptuous breasts against his chest and feeling her soft mound now pressing against his stiffness.
