I was having a sleepover with a friend back in middle school, one night I woke up and heard a sound of something squishy and slowly turned my head and saw my friend laying on his side f******** his own a****** with his left arm and his right to j******* slowly. He did this for a while then started to breathe harder. He stopped then got up and head straight to the bathroom down the hall, after i heard the door closed i got up quietly and got near the bathroom door in time to hear a few grunts with a sound of something thick hitting the floor multiple times and that’s when I realized he went to the bathroom to c**, I immediately went back to back bed and a few minutes later he came back and went to sleep.
