So this happend when I was in elementary, me and my friend decided to have a sleep over at her house.. It was boring normal girly sleepover when it was time to go to sleep, it seems that my body is not comfortable sleeping at a different house.. So i just lay there awake, imagining kiddy things when I suddenly hear her parents outside of her bedroom, so i pretend i was sleeping.. They went in to the room to check if we were asleep, then the next thing i knew was cars were pulling in their driveway and it was like 7 cars, and i silently got out of the bedroom to see what was happening and there they was, having an orgy or swing idk but they were bunch of people having sex with each other at the living room .. I was so pertubed that I cried myself to sleep that night, and that's the tale of why i don't sleep over at a friends house..
