The packed bus was filled with office ladies on their way to work. My crotch was tightly pressed against a butt through a tight skirt, and the black pantyhose legs extending from it were oddly erotic. I couldn't help but get an erection, and I tried to push my cock against the crevice of the butt or the area around the pubic mound over the skirt. When I lifted the skirt with my cock, the OL seemed excited and grabbed my cock tightly. We have to do it!
