like a week ago i decided to go to a party my friends invited me to, just a normal party till 12o'clock where it gets intense, im 16 and kinda a shy type, which recently broke up with my girlfriend so, i wasn't really comfortable there, but my friend was my ride home so.... i stayed till i heard of the dark room (its a room where all lights are tuned off and you go and make out, in mid dark till they turn the lights on) well i was down about my girlfriend but friends told me thats the best way to let go her so i decide to go. i get there just in time right when they turn off the lights and start feeling around till i find some boobs (toke a while and some uncomfortable touches) but finally got some boobs. couldn't see her face pretty good but she looked kinda hot so, we made the fuck out, like never, then started to rub my dick and i sliped in her panties and fingered her while making out till lights came on... and saw who i was kissing, which was my lil sis of 15, i didn;t even know she was at the party my parents told her she couldn't go, so the last person i thought it could be was her, i was so ashamed of everything and feeled all yuck about it, i got coments about my friends and all saying she is super hot and sexy (she is mid height, chocolate long hair color, big green eyes, white skin, kinda goth attitude and looks, pink kinda chunky lips, not to fat not to skinny) but anyways we were like all over each other, we both sweared at the party, we weren't going to tell anybody, then i asked her is she liked it and she said well you kiss better then my last bf and than she asked me and i said maybe, then we both just looked at each other and started to get closer and like an inch away we both went "ewww" and went back. so i haven't told anybody about this till now couse i just can't hold it in anymore
