My roommate let me fuck her after her yoga session.

Every morning his roommate had a specific routine that she hated to change, she would get up go to the bathroom, get a protein shake and start her yoga session, she always wore clothes so tight that he would go crazy just looking at her.  That day he couldn't take it anymore, seeing her on the floor, flexing and lifting her butt was too much. The fabric of her pants showed her vaginal lips, they were so pronounced that he had to touch them already, he approached her and started to touch her ass, he waited for her to push him away but instead she let him touch her and even asked for more, it wasn't long before the clothes were gone and he could penetrate her.
