Even though you are four years older than Janet, you get on pretty well together. When she was younger, she was just a pain in the neck, but as she grew up she became a lot more fun and was surprisingly good at football and cricket. However, since you discovered wanking, you have been spending more time on your own which has made her wonder what it is you get up to in the bathroom.
On a blustery day in April, far too wet and windy to go outside and play, you're both sitting on Janet's bed playing draughts. You're usually pretty evenly matched, but you've already beaten her twice and now it looks as if you're going to beat for the third time when she "accidentally" knocks the board over sending the pieces flying.
For some reason, this really annoys you; "you always do that when you're losing," you say hotly. (As you say it, you know it's not true)
"I do not, and anyway I wasn't losing," she says, going red in the face and getting up on her knees.
"You do too." You're not going to back down now and you get up on your knees facing her, then, without thinking, you reach out and grab her wrists. She squeals and tries to get away but you use your superior weight and strength to push her back and pin her to the floor. You end up with her flat on her back with you on top of her; you look at her flushed, angry face and feel guilty. " I don't want to hurt her. She's my kid sister, my best friend," you think.
She opens her mouth to yell at you and without thinking, you lower your head and press your lips against hers. At first, she struggles, trying to get away, but after a few seconds, she goes limp and starts kissing you back. You've kissed Janet loads of times, but never like this and what starts off as a rather awkward kiss with your dry lips pressed against hers, soon becomes something more. You remember something you've been told about and push your tongue forward.
The unfamiliar sensation makes you pull away and you let go of her arms expecting her to shove you off, but instead, she just lays there looking into your eyes and then she pulls you down and kisses you back.
Your head is saying, " this is wrong, she's my sister," but your body doesn't care and you soon become aware that your stiff cock is pressed right against her groin.
