All this happened at a party when I was much younger.
We were at an older friends house, she celebrated her 19th birthday. She always had a rich and extravagant family, so it was a sleepover party. We were three girls [Sally, birthday girl. Italian, dark hair. Annie, tiny blonde with short hair and a radiant smile. Nadia, chubby shy girl] and four boys [me, scrawny funny guy with glasses. Luke, tall shy dude. Nick, popular handsome kid. Danny, the class clown] – boys were intended to sleep in the guest room and the girls in Sallys super king size bed. Her parents cleared the area after the main party actions were over, probably to have some alone time themselves. We all retreated to Sallys room, where she had a computer with flat rate internet – a miracle back then. We did typical kids stuff like pretend to be someone else in chat rooms and everyone chimed in what to type for maximum fun. It got us in a really lighthearted mood, and someone suggested we'd play a card game. After a few rounds, someone said "let's make it interesting" and suggested we'd play a raunchier version of the game – the first one to drop out of a round would have to do whatever the winner of the round dared them to do. Basically a slower but fun "truth or dare".
