Damn, that was hot!
Jenny was not the most popular girl in school nor was she model material in any stretch of the imagination, she was cute and she was very fit and had a lithe body that many guys liked. She never really lacked for dates. Her smallish tits didn't really require a bra, but she wore one often because her nipples were in a constant state of erection. She did get a bit embarrassed about that.
Jenny also had that hot little 19-year-old body that drove the older guys wild and her older brothers friends were constantly asking her out. She seldom took them up on their offers but when she did go out with them; all they wanted to do was get in her pants.
Ron, being 26, liked his younger sister, and due to the age difference was not really close to her, but he often helped her with her studies. Seems he got all the brains in the family. Seven years was not a lot any more, but while they were growing up together, had very little in common.
He was now in college and lived in the dorm, which meant that every weekend or break he was home as dorm life sucked to the max. He worked hard to keep himself in college and he studied hard to maintain high grades.
His late start in college was due to that war in Iraq where he spent 3 years in the Army. He was wounded in the shoulder, which limited his mobility somewhat, but wasn't real noticeable until he took off his shirt. Being wounded meant that he would get some benefits when he got out of the Army but not enough to make a decent living off of, so off to college he went.
Now in his senior year he was not the jock in school, but he loved the water and spent many days at the beach or in the community swimming pool so he was toned, but not real muscular. He did go out on dates somewhat, but like his sister he was not the most popular person around. His friends were the usual mix of people and his demeanor meant that his friends were close and real.
Ron and Jenny's parents both worked for a living to make ends meet and that meant they were often not at home. Both of the kids had learned from an early age to take care of themselves and were both very self-sufficient.
Being on their own they had often seen each other in their underware or in some stage of semi-nakedness but never really thought much about it, which is untill Jenny celebrated her graduation.
The family was all there and very proud of her accomplishment and she ran up and hugged Jim and Sally, her parents and turned to hug Ron. She pressed her body tight against him and whispered into his ear that she was grateful for all the help he gave her through the years and hoped that she could repay him for his assistance. Ron reacted immediately as his cock stirred in his pants and pressed against her leg.
Embarrassed, he tried to step back but Jenny held him close and, did he imagine it? She seemed to be rubbing against him. No this can't be happening, she wasn't doing this, it must be his imagination. Jenny let go and moved back a bit looking at her older brother with a sheepish grin and a slight twinkle in her eye. Ron hoped she would not move to far away as his erection was still tenting his pants, but no longer rubbing against his sister.
Jim looked at Ron and asked, "Everything alright son?"
"Yeah, yeah everything's fine dad."
The question took him off guard and also had an immediate reaction on his dick, which shriveled up and returned to normal. The family went home and had a nice BBQ for Jenny's graduation. The back yard was filled with family and friends and the booze flowed freely. The thought of what happened earlier never left Ron's head, but now he was enjoying the Sunday afternoon along with everyone else.
Jenny jumped on the bed and Ron was startled into conciseness with a raging headache.
"Wake up sleepyhead."
"What time is it?"
"Time to get it up."
Through the fog in his head he reeled and suddenly snapped awake. She did it again? He looked at her and she was dressed only in a t-shirt and panties that left little to the imagination. His cock stirred immediately and he shifted in the bed to hide his obvious erection.
"What?"
"C,mon, get your butt outta bed, we got things to do."
She grabbed at the sheets and tried to pull them off, but he was awake now and held onto them so that she would not see his erect penis. This only egged her on and she jumped on him and started to wrestle the sheets off. She sat on his lap and when she did that he was forced onto his back and now his erect cock was rubbing on her pussy and he knew that she had to feel that.
The embarrassment of this scene did little to abate the situation as now his cock was millimeters from her hot pussy and he swore he could feel her lips part to rub against his continually hardening cock. He tried to push her away and his hands accidentally slipped up her body and under her t-shirt. What a feeling, her tits were firm and small but her nipples were so hard they could cut glass. She leaned forward so that his hands were trapped between them and he couldn't move them.
Now she was doing it again, she was rubbing her pussy against his ever-stiffening cock and there was no denying what she was doing. His hands, trapped on her tits, took on a mind of their own and he started to massage them. Oh how he loved this feeling of this young lady's tight body against him and making him feel so wonderful. Then she kissed him on the lips, not that brotherly, sisterly kiss, but a deep and passionate kiss.
He was a bit startled and opened his mouth to protest only to find that she was filling it with her tongue. He succumbed and let this wanton vixen have her way. The pleasures were so much and he felt the ejaculation eminent.
