My sister can be the biggest pain you've ever met but she can be lots of fun to. She's very pretty but she set me up with someone she knew had crabs and I caught them. Boy did I catch them,so thinking about how I could get her back me and a few friends on mine brought a lot of beer to her and her b/f's apartment. Well my sister loves to party and get sloppy drunk and her b/f don't drink and hates it when she does so he gets all pissed off and leaves and we know she won't quit til she passes out. She's 3 sheets in the wind down to tjust her shirt and panties oblivious to where she's even at and she passes out. She purposely gave me crabs by setting me up so I take her panties off and rubbed myself all over her even her mouth,now we are brother and sister so I didn't fuck her,ok. I did strip down naked and pull her upon my chest and went to sleep,she woke me up screaming which scared me at first then I realized she took the bait and she thought we had sex and boy I'm still milking that one and haven't told her yet we didn't. She was soo upset she told our parents which was furious with us both over it and gave us the lecture on why siblings shouldn't be intimate with each other. Omg I almost fessed up but couldn't do it and she caught those crabs which made it a hundred times worse on her and we see the same family doctor and he gave us the talk on why incest was a very bad idea. Now everybody in our hometown knows us as the crab family and my sister's moving after her and her b/f broke up over it which I didn't like him much anyway which is a good thing that came out of it. I'll tell her the truth probably by this weekend but don't know if she'll believe me.
