It’s not a wild story and the title says it all. I still want to tell the story and share some details.

Usually my gf and I spent the weekends at my place. Today (saturday) she had an appointment at her hairdresser at 9:00am so we stayed at hers. She lives with her mom, dad and her brother.

We got up, I drove her to the hairdresser and got back to the apartment and just stayed in her room. Her parents were both working so only her brother and I were there. I think he forgot, that we stayed this weekend there.

My gf’s room and the bathroom are directly vis-a-vis and the walls are thin af. That’s why we never fuck at her place.

While hanging around in my gf’s room I heard that her brother went into the bathroom but didn’t close the door. Didn’t really noticed that at first. Then I started hearing those fap noises. Those fap noises that went wetter and wetter. Spoiler: I didn’t do anything.

But since I am bi curious like crazy, I had so many scenarios running through my head. Should I get out of the room “to get myself a drink” and catch him and start helping out? Should I send him some kind of gay porn where one guy catches another one who’s masturbating and they end up fucking? Would he come in his sister’s room to search for some panties and bras? My mind went crazy but I could control myself and just stayed in the room.

He was done pretty quickly (like within 2 minutes). And then he went back to his room. Even tho that this was a missed chance, I am kinda happy, that I stayed in the room, because he is a massive introvert and I am sure he would die if someone catches him masturbating. And I also don’t want to cheat on my gf.
