Had a girlfriend that would do this to me, before she got dressed when she was about to go out with the girls on Thursday nights if I ever gave her grief about it. If she already had her panties, pantyhose and heels on she would just sit on my head and give me a blow job. Either way, I was always pinned until I submitted. And of course, she would tell me not to wait up for her before walking out the door. She would also say if coming home if I was still up at 4am, "What you don't know, won't hurt you"
