I'd have you hold her legs open while I fuck her and her looking at you telling you how good my cock feels and you telling her to make sure she makes me cum and fucks me good
the first time, with her tits pressed to the wall, biting her upper back, and pounded deep in her pussy. second time stuffed down her throat to the hilt. third time, all over her face and chest. then just as she's about to leave, i'd twirl her back pressed into the door; one hand gripping her neck; the other pulling her jeans and panties down to mid thigh, and jerk myself off till cumming into her panties. pulling them up and making sure my cream is rubbed firmly into her slit.
the why of it, 1 so she can feel me fuck hard and breed her like an animal. 2. because it's one of my favorite feelings, 3. to show her how pretty she looks painted in my cum, and 4. so she can feel me all the way home with every step.
