There's a girl in my classes that I always work on homework with her at her apartment. Almost everytime I'm with her, she's wearing her pajamas. But she doesn't wear a bra or panties, because her pants are pulled down a little so I see her ass, which really turns me on. One time she was sitting on the floor with a skirt on, and when she stood up, her feet got caught in the skirt, and her skirt and panties fell down, I just wish I was looking at her when it happened, I only saw a glimpse. Another time, we were in class, and she bent over to pick something up, and I got the perfect view of her cleavage, because she was only wearing a tank top under her shirt. Later that evening, I was having a conversation with her while she was changing her shirt. She took off her shirt and kept only her tank top on and no bra.
