When I made my beloved sister, who has cute double teeth and suffers from sensitivity to cold, wear black tights of various deniers, her body became unable to live without black tights. One day, I got horny with my girlfriend's lovely younger sister wearing black tights, and when we rubbed each other (intercrural sex), she felt so good that I ended up peeing on her. I couldn't hold back anymore, so I tore off my black tights and had forbidden sex.
