"Turn round," you say and when she doesn't understand, you catch hold of her waist lift her around so that her pussy is right in front of you. You look at the wrinkled little entrance to her bum, but it's her pussy you're interested in and you pull her back so that it's right over your mouth.

You try to get your tongue inside, and you can feel her responding but after a few minutes, you have to push her off because you can't breathe. For some reason, she starts giggling and that sets you off as well and then she offers to suck you again, although she doesn't seem very keen.

"I'll tell you what; why don't we both get ourselves off at the same time," you say. She seems to like that idea and she lays on her back with her hand down between her legs. You sit up to get a better view and as you watch her sliding two fingers in and out of her pussy, your hand is wrapped around the shaft of your cock, sliding it up and down. Even though you've already cum twice, it's not long before you climax again but this time there is only a dribble, and most of it ends up on your belly. She is still rubbing herself and, acting on impulse, you scoop up some of your spunk and push two fingers right into her vagina. With the spunk and her juices, it's really slippery in there and suddenly she's making moaning noises and gasping as her climax hits her.

When she calms down, she sits up and looks at you. "Wow! she says. That was the best ever. You want to kiss her again, but she wriggles out of your arms and before you know it, she's gone. You go into the bathroom to clean yourself up and as you stand, peeing into the bowl, you can't help thinking how close you came to fucking your baby sister.

You think about the things the boys at the village school used to say they'd done with their sisters, things that you thought were just wishful thinking and imagination and now you think that maybe they were telling the truth.
