You're Billy's girlfriend and he has a step sister who he hates.
You're sleeping over at Billy's but instead you ended up having boom boom in bed. You two knew that Steve, Nancy, Robin, Eddie, Max, Lucas, Mike, Eleven and Dustin were here cause they were hanging oht eith max bjt you both didnt care.
The room is filled with loud moans and each others names. You both are naked and billy is the one on top, suddenly Steve comes in without knocking with an irritated face.
"Can it be quiet? There are kids here."
He says sternly, (with the kids he meant Lucas, Dustin, max, Eleven and Mike since they're 15/16 and steve, Nancy, Robin and eddie are 20/22)
Billy rolls his eyes and lays next to you. He strokes you're hair and looks at steve.
"How weird of you. Just bursting into the room just to see my girlfriend naked..."
He says, steve face goes a bit red but he can't help but look at you're body. Billy notices eddie behind the door peaking in and he rolls his eyes.
