Chapter 1

Bob had had a longterm sexual fantasy that he'd never been bold enough to try and make a reality. He'd had the sexual hots for his younger sister, Missy, since she'd entered puberty and began to develop the budding sexy body of a young woman. He couldn't remember how many times he'd actually jacked off with the visual images of his younger sister in his head and on a few occasions, he'd even been able to watch Missy sunning in her sexy black bikini out in the backyard while he was watching from a bathroom window upstairs and stroking his cock, wishing he was fucking her sexy hot young cunt. Nearly every afternoon or night, sometimes even in the morning when he'd shower for school, Bob would start thinking about various times he'd seen his younger sister around the house in different states of being dressed or undressed and times he'd seen her out in the backyard sunning in that totally hot sexy black bikini she'd bought for that very purpose before summer started. Bob's cock quickly responded whenever he was thinking of how sexy and cute Missy was and before he knew it, he had a raging hardon to deal with and he always dealt with an aroused cock by jacking off.

While Bob knew he'd wanted to fuck his own sister and she was a very attractive and very sexy girl, he'd never been willing to try sleeping with her while she was still under-age. He figured if their mom and dad found out he and Missy were fucking together, he'd be in enough trouble, but if she was under 18 years old, he knew he'd be in bigtime trouble for sure. He knew that most people would frown on a teenage brother and sister being sexually involved with each other, but if the girl was under-age, he felt sure that would gain even further negative reaction and he didn't need his tight muscular ass in anybody's crack for boinking Missy even though she not only needed to be fucked, but he felt sure on many occasions she was teasing and trying to get him to fuck her.

The summer after Missy had graduated from high school and had officially turned 18 years old, she and her brother Bob were left at home in an old farmhouse that they lived in with their parents while their mom, dad and younger sister all left for the evening. Bob was in his room using the Internet and getting fucking turned on when he heard sounds telling him that Missy had gone down the hallway to take her nightly bath. He felt his cock growing hard as he envisioned Missy being naked except for the robe and possibly a thong that she normally wore to the bathroom for her bath. Bob gave Missy a few minutes to get in the bathroom and run her water and get naked before he snuck down the long hallway to spy on her when she was naked and totally exposed to his gaze.

Bob had been lounging in a pair of gym shorts and one of his workout shirts while he'd been in his room. He found that to be a very convenient manner of dress when he was looking at things on the Internet or reading a sexy magazine that prompted him to uncover his cock and enjoy a good session of jacking off. Bob left his room and he could hear the radio playing in the upstairs bathroom so he knew Missy had already run her bath water and was in the tub washing. He made sure he was very quiet so his sexy younger sister wouldn't know he was checking her out. Bob had done this before lots of times but now he found Missy even sexier and more arousing than he had in the years since she'd entered puberty and developed the increasingly sexy and nicely shaped body of a developing young woman.

Bob got to the closed door of the bathroom and he slipped his gym shorts down off of his already partially hard cock as he bent over and got his eye centered on the keyhole in the bathroom door so he could sneak some sexy peeks of his sister Missy's naked body as she bathed or as she got out of the bathtub. Bob's cock reacted to both his hand jacking himself up and down gradually as he angled until he could see Missy reclining over in the far end of the large bathtub. Missy had the sexiest medium-sized breasts Bob had ever seen on a girl. He didn't fucking care if she was his sister, Missy had nice sexy rounded breasts and they were topped by two of the darkest and sexiest round nipples he'd ever seen on any girl he'd ever been with. Bob had snuck enough peeks at Missy by now that when he jacked off, he could clearly see her naked tits in his head as he stroked himself to a hard powerful cum. Bob knew that Missy wished her breasts were a cup size bigger than the B-cup that she currently was wearing, but he thought her tits were just right. Bob had occasionally snuck into Missy's bedroom and gone through her bra and panties drawer, pulling out some of her sexy bras and using them for arousal and stimulation as he jacked off. He'd even shot his cumload into the cups of one of Missy's bras on occasion and he'd then wiped them out and wondered if Missy had ever known someone had jacked off in her bra.
