Pamela, Billy's kid sister was about to turn eighteen and already she was the biggest tease in the world, to make matters worst she had chosen Billy to be the subject of her torturous teasing. Pam was a beautiful girl with the body of a men's magazine model and the face of a Greek goddess, she knew it and she used her looks to get anything she desired from whom ever she chose; it was Billy's turn as she had decided that she wanted him to be her first. Pam had always had a crush on her brother and as long as she could remember she had dreamt of him making love to her and taking her maidenhood.
Billy was not a bad looking boy but he was extremely shy to it came to women, he had only gone out in two dates and nothing really came out of any of them. To make matters worst both girls had made fun of him at school and everybody thought he was a dork; having Pam as a sister didn't help him at all, she had a very outgoing personality and everybody liked her, dating was no problem to her and she had dates almost every weekend. But Pam's mind was set on having herself to her brother and she never let anyone into her pants, no matter how hot she was or how much she wanted to feel what making love felt like; she was saving herself for Billy.
As her eighteen birthday got closer she began to conceive a plan on how to get her brother in bed; Pam realized that the only way to go about it was to get him as horny as she could until he couldn't take it anymore so he would comply to her wishes, and the only way to achieve it was to tease him as much as she could until he gave in. With her plan all set she waited patiently for her birthday to arrive, in the mean time she prepared herself to be as sexy and attractive as she could be for her brother. Pam went to a beauty parlor to get her legs waxed along with a trimming job on her pussy; she wanted it to look as inviting as possible, she wanted to have her pussy bare except for a small heart shaped patch on the top.
The woman at the parlor did such an excellent job that when Pam saw her shaven pussy, she got so aroused that she could actually see her cunt lips swell and she felt the moistness in her pussy. If she had been home she would have fingered herself for sure, but she bit the bullet and waited for her brother to the honors. After that she went to buy some lingerie for the occasion; a black lace with embroidery in the front thong and a matching bra which made her breasts seem bigger, a black garter belt and black stockings; she looked incredible in her new attire as her ivory skin contrasted with her black outfit. Then she bought a black cocktail dress with enough cleavage to make any man turn his head; a pair of high heels completed her outfit.
From the day of her birthday party Pam started teasing her brother; she would leave her bedroom door open when she changed clothes knowing Billy could see her from across the hall, she wore only a short t-shirt and the most revealing panties she had when they were alone in the house, bending over pretending to pick up something every time she saw Billy was behind her, giving him a great view of her butt. When they were in the kitchen Pam would rub her tits on Billy's back as she passed behind him; she even asked him compromising questions about her body, if he thought her tits where to small or her butt to wide while she lifted the t-shirt exposing to Billy either her naked breasts or her thong clad butt. With her plan starting to develop she just had to wait for the perfect timing and it came when their parents announced that there was a family emergency and that they had to leave in two days to go visit their sick relative; it couldn't have been more perfect, now it was time to work harder on Billy.
Billy was falling into Pam's game as she made him hornier every day; it was hard for him to conceal his erect dick from Pam every time she teased him, he even had to ran to his room a few times to jerk off because she got him so hot that he couldn't take it anymore. Of course Billy wondered what was going on with Pam, was she doing it on purpose or had she just simply lost her mind; it didn't matter, he got to watch her sister's naked body all the time and he loved it; it was a once in a lifetime experience for him, the closer he had ever been to a naked woman was his nudie magazines and the internet.
The day before their parents left, Billy overheard a conversation between Pam and one of her girlfriends while they were at her room. He listened closely as Pam told Carrie about her plan and what she had been doing to him; at first he was stunned by the fact that his sister wanted to sleep with him, but then his shock turned into lust as he remembered how many times he had stroked his dick thinking of her and wishing that someday he could screw her, so he decided to go along with Pam's plan and then he was going to try to get Carrie involved. He had always liked her and she was also a very attractive girl; she had been in the cheerleading squad since junior high and she had a magnificent body. As he pictured both of them naked with him on a bed he felt his dick growing to its fullest, that was all he needed to make him grab a bottle of baby oil and go jerk off picturing his sister and Carrie banging him.
That day when Carrie left to go home Pam continued to tease Billy, again lifting her shirt she asked him about her tits; but this time instead of blushing and turning his head away, he told Pam that in order to give her an honest answer he would have to take a closer look. Billy got his face as close as he could leaving only a small distance between Pam's tits and his face, then he stared intently at his sister's tits pretending he was trying to determine if one was bigger than the other; after five minutes he moved back and as seriously as he could he announced the results, he told Pam that in fact they seemed the same size and even told her that he thought they were extremely beautiful and that any man would be happy to touch them. Pam unsure on what to say just saw her brother walking away leaving her with her tits exposed right in the middle of the living room.
That night as they were getting ready to go to bed, Pam left her bedroom door open as she had been doing for the last week; as she was changing into her pajamas she felt Billy's eyes glued to her body, she felt relieved that he was still looking and she knew he was still trapped in her little game. Before she put her pajamas on Pam decided to make the final attack on her brother, she was going to put on a show for him. Carefully she pretended to close her door leaving it slightly open so Billy could still see inside, she turned the lights out leaving only the dresser lamp on which illuminated her room enough for anyone to have a perfect view from the outside; then dressed only in a pair of pink cotton panties she placed herself on the bed and started massaging her tits making her nipples hard in no time, then she caressed her legs with one hand as the other was still toying with her nipples. Billy aware of what was going on quickly turned the lights in his room off and sat o a chair which was perfectly placed and allowed him an unobstructed view into Pam's room, he was amazed by his sister's movements as she tugged on her breasts while she moved her hips in a very inciting way.
Pam was really getting turned on by her own gentle touch, she could feel her panties getting wet as her pussy tingled with desire; Billy had already taken his dick in his hand and was slowly stroking it in rhythm with Pam's actions, he almost blew off when Pam placed her hand over her crotch and pressed on it firmly. Out of the corner of her eye Pam saw what Billy was doing while he was submerged in the shadows of the night, she smiled to herself knowing to well that she finally had him and it was time to leave him hanging; abruptly she stopped playing with herself, grabbed her pajama top and put it on, then she turned the light out and she went under the covers leaving her brother with his dick on his hand and horny as hell. Billy almost died when she ended the show but the he realized it was just part of her plan to seduce him; he too went to bed without getting himself off because he wanted to save all his sperm for his sister.
After their parents left the next morning Pam wanted to tease Billy a bit more; she went to sunbathe in the back yard by the pool wearing the smallest bikini she had, the top barely covered her tits and the bottom was so small that it crept between her butt cheeks and showed perfectly the outline of her recently shaved slit. Pretending to be bored she asked Billy to join her, after a while she asked him to rub some suntan lotion on her back; nervously he applied the oil over her soft skin as gently as he could manage, he wanted to rip the bikini off and to jump on top of her to give her what she wanted, but he kept his cool knowing she was going to give herself to him willingly. When he was done doing her backside Pam rolled over on her back and asked him to continue with her front; Billy was more than happy and had huge erection that Pam could clearly see, without missing a beat he rubbed lotion all over her flat belly and thighs. All this friction was having the same effect on both of them as Pam felt she couldn't wait any longer to fuck her brother, and Billy felt his dick was going to explode from all the sexual tension he had been put thru all week. Regaining her senses Pam just stood up rapidly and jumped into the pool to cool off, Billy on the other hand left her there and went inside to watch TV fighting to keep the bulge in his shorts away from Pam's sight.
