My wife and I have sex usually twice a week. She also loves to give head. She says easiest way to keep me level headed is to keep my balls empty.
So about 2 months ago she was giving me a blowjob and she stopped. She said, "Would you ever let me fuck you?" I said, "You fuck me all the time." She said, "I mean like me with my strap on. You bent over and me fuck you." I said, "You don't find that a bit gay?" She said, "This coming from the guy who has sucked dick?" I said, "True." She said, "So? Would you?" I said, "In the interest of science? Sure." She said, "Really?" I said, "If you really want to, I'd be up to at least try."
She fucked me that night. She gets me loosened up with a traditional strap on but switches to a strapless strap-on when she wants to cum. I must say I'm kinda hooked. She has fucked me probably once a week the past 2 months.
