Not a super exciting or unique situation for many, but last weekend was the first time my FWB borrowed a swing frame (or another friend left it there). Following our typical foreplay and my clean-up/out in the shower, I had my legs ankle cuffed for the first time. He left my hands free at times, handcuffed at others. There I was on my back, arms and feet overhead while my ass was free for the taking in this sex swing.
He got me higher than I've been in a long time with his exhalations from vapes and bongs in the room during breaks as he banged me repeatedly, taking breaks for drinks, private time in the bathroom, etc... Really enjoyed this level of submission with the swing. He came once in my ass, and following a break, he was able to get hard again. We finished the night coming together.
He's out of town this weekend on a business trip, but he's trying to setup a small party with a group of friends for next weekend for my second experience in the swing with a few more cocks being involved.
