Strange Obsession

Happy mwm with sweet sexy younger wife. Have had a few sexual adventures over the years but nothing for a couple thanks to the worldwide health crisis. Been fantasizing together and hope to get out for some real play maybe this summer.
Anyway, have been talking about and getting excited about sharing her charms again. Top of the list is her wanting to suck some strange cock like at a glory hole situation.
This is actually not about that though.
My confession is that lately I've been getting off to something even kinkier. We both like when I do some creative rope bondage on her and I'm imagining her tied in such a fashion that her crotch is wide open at the edge of a swing-chair hanging from the ceiling and she's being fucked by a long slim dick. Once it's wet with her c**t juice he rubs it on her asshole and she's begging for him to fuck her up the ass. I watch from right next to her and see that dick plunging in deeper and deeper and when he dumps his load he pulls it out and I get to suck her goo off his dick and then get to soothe her sore hole with my lips and tongue and drink that creamy load out her beautiful pink ass.
