My wife tried fucking me with a strap on once before, it wasn't great for either of us, but we wanted to try again.

This weekend we rented a special air-bnb that has all sorts of equipment for BDSM play, including a Gyn-Chair. We had been there before and I had fucked my wife on the chair, but this saturday my wife tied me to the chair and put on the strap on again.

She started fucking and stroking me at the same time and I freaking loved it, and started to moan. She was slow at first and really used her hand to make me twitch, it was pure joy. After some time, she started to fuck me harder, grabbed my legs with both hands and really hammered down on my ass. I could see how much fun she was having. I used my left hand to stroke my cock, while she fucked me even harder. It didn't take long until I started shooting cum all over my belly, just a tremendous orgasm.

I later made her orgasm twice, so she can't complain I wasn't pulling my weight :P
