After I moved from home (18/19m at the time) I lived in a share house with 2 other students. One of them was a friend(18f), and we’d spend a lot of time together. I was single but she had a boyfriend, and he had no idea how close we were. We’d watch tv until late, sometimes on her laptop in her room, in her bed, and eventually we’d just end up sleeping in the same room.
I realised pretty quickly that she wanted me, and I had a great time teasing and tempting her. I’d wear nothing but a t-shirt and boxers on the couch or in bed, so she’d get constant glimpses of the outline of my cock or my morning wood.
She’d respond by wearing little silky shorts with no panties and lowcut or tight tops. She’d “accidentally” give me little glimpses of her shaved pussy and I’d deliberately watch risque movies with her so I could watch her pants soak through at the fleeting glimpses she’d get of my dick. That she wanted me was obvious and I wasn’t against fucking her but I got off on the teasing.
