So this happened over the weekend. Sorry about the writing im not a writer . A new friend from Uni invited me over to do some study at his accommodation. After downloading some materials to study he was looking for them in the folder on his laptop when a picture of his girlfriend came up. As I was sitting on the bed and he was on the desk in front I saw it. It was not a nude but she was wearing a bodysuit that was see through and barely covered her pussy. He quickly closed is embarrassed and apologized saying he was sure I didn’t want to see that. The thing is having moved from home to uni made me act more freely and that has lead to most people I meet assuming i’m gay. Though that is not to far off I have only had sex full with girls despite messing with only 3 of guys before. I explained to him I am bisexual and I rather enjoyed the picture. We talked more about the subject and he seemed curious asking me a lot of questions. Eventually he asked me if I wanted to see his girlfriends picture again and if it has any effect on me. He showed me a few more pictures which were not nude asking ”are u telling me this can make u hard? I assumed you only liked guys” . I was already horny at the hint of his girlfriends big tits . Again we continued casually talking about the sex until her asked me how big I am. He continued making jokes about how he cant imagine me with a girl
