I was just arriving back home where my roommate Ansel Elgort was living with me. Yah I know it's crazy to think that a celebrity is rooming with you! Anyways we live in a little cozy apartment where the hallway connects all the separate rooms and bathroom. The walls are very thin as well, they're not sound proof at all. Anyways once I arrive home, I go to my room changing after a long day and just ready to chill in my room. While passing Ansel's room I hear a light squishing slapping noise. I think nothing of it. I get up to get a glass of water this time and suddenly hear Ansel moaning. It was obvious what he was doing at this point. I peaked in his room and you can see the swift motion of an upwards and downwards motion under his covers. He was masturbating. I watched for a few minutes until he pulled the covers off his cock and revealed a nice 6 inch dick that was slim but long and he had big balls. His cock was trimmed, not shaved and he was just jerking it with baby oil spilled all over his cock. As he was about orgasm he arched his back and a fountain of cum just busted out of his cock and all over his v line and his pubes. It was all over his abs and he orgasmed so hard he dropped his phone on the ground. I was surprised to see him watching gay porn. He cleaned up and looked at his door almost catching me but I slipped out in time. As I was getting my water like I originally intended, he walked out of his room in just loose boxer briefs where you can see his semi hard cock outline from moments before. Once he saw me he was shocked. He asked "when'd you get home" I said "just a few minutes ago". He was nervous and asked "I didn't hear you come in, did you hear or see anything" I said "no", knowing I saw his massive penis earlier. He headed to the shower and that was it for the night.
