Mixed Doubles

Wife and I are quite fit and have rather high libidos. Enjoy a variety of sex options including toys and pre pandemic play with others. She's very, very much an anal slut. Comes like a train when her arse is stimulated by anything from a light licking to finger stretching to full blown deep as can be anal sex.
Lately she's been fascinated by more and deeper fingering and can nearly take a fisting. She sometimes even has wet squirting orgasms from being nearly fisted.
She has opened up that she imagines being DPd up her arse by me and another cock at once.
I have no problem with that and can only imagine how amazing it might feel to have another hard throbber squeezed tightly against mine as she spouts the filthiest language begging for us to ream her out and wreck her clutching rectum. Hope we can make it happen soon.
Anyone ever have anal DP experience? Love to hear from men and ladies and any combination of gay, straight or bisexual orientations. Would be interested in a variety of perspectives.
