HUNTA-599 I had always thought she was just a regular female friend, but the moment she put on that 'sweater that's too stimulating for me'...! We missed the last train while drinking with my female friend, so we ended up continuing to drink at my place.

I ended up drinking again at my place with my girlfriend who missed the last train. I lent her the 'lewd sweater that confuses a virgin' since she doesn't see me as a man, and she happily put it on, but it was too erotic and I involuntarily got an erection! In the awkward atmosphere, we decided to go to sleep... of course, there's no way I could fall asleep! Unable to resist any longer, I groped her exposed breasts and butt, and she let out a lewd moan! Her panties were soaked through, and when she begged me, I couldn't hold back anymore and inserted my raw penis into her vagina!
