I was not aggressive and in fact very timid not being sure what was happening. She then shocked the heck out of me and asked if she cold suck my cock and for me to leave my uniform on but lower my pants. I felt like I was being set up and was ready to leave and then her husband said he was okay with it and. His voice thrown over his shoulder, "You stay down here tonight, in that position, all night.
