I (f22) was at my apartment and my roommate decided to have some friends over. I like taking baths and reading my book so I decided I was going to do that. They were playing some board games so it was relatively quiet. Even so, I put my earbuds in to drown out the noise. This meant that when one of her friends (m23) walked in to use the bathroom I didn’t realize. I felt a presence in the room and looked to my right (my back was to the door so didn’t see him walk in either) and found myself staring straight at his dick because I hadn’t bothered to draw the curtain. He started peeing and didn’t even realize I was there until about halfway through when he looked over and saw me laying there completely naked. He looked kinda startled and tried to pinch off his pee but it was kinda hard to do that since his dick kept growing haha. Now he was wrangling a boner while trying not to pee while also trying to pull his pants back up and not look at me. We were both laughing at this scenario but a part of me was also pretty turned on
