well yesterday me and my friends are hanging out at my friends house, his parents being out of town so we were playing a version of spin the bottle. basically if you get picked you put on a blindfold go into a dark room and wait for one of the girls to go in and make out with you. in essence the girls get the choice of making out with the guy they like or whatever and the guys get to feel some titties and ass, granted it may be some ugly chick,but that is what the blindfold is for. so after a few beers and joints everyone is a winner. well i got the bottle and had to go in to await my mate. pretty soon she comes in and i go to town licking her armpits and tits and grabbing her ass and just generally stopping short of inserting my manhood into the moist confines of this broad. everyone outside is laughing , but with the beer and joints who wouldn't i figure i got one of the homely chicks ,but i don't care cause she can kiss good. finally i notice she has a blindfold also and go WTF? so i say why are you wearing one. and then she speaks......and it's my godamn sister!!! she had gotten to the party with one of friends right after i had gone in. and they told her party rule was she had to go in and make out with the guy in the next room, which was me. i spent the rest of the night puking.
