Roommate Getting Fucked while I Listen and Rub my Pussy

When I got home, I heard some weird noises coming from my roommate's room. When I got closed, I heard she was fucking, possibly with her new Tinder date that she told me she is getting out with today. I undressed, sat by the door and masturbated while they were fucking. I decided I record myself in the mirror, I was watching myself while I was masturbating. That could be my next new thing. You always learn something new and what makes you horny. And I think we all came at the same time...
