A couple boarded a crowded bus, and the wife was pressed against other bodies, her heart racing. Next to her husband, her mini-skirt left her bottom exposed, and she felt a stranger's penis against it, causing her to unconsciously clench her hand. The man, of course, was excited about the possibility of public sex with his wife next to her husband. To avoid being noticed, he slipped her panties aside and had his way with her right there.
