From the women who like their pussies and clit ignored, it's the best experience. To me, they seem like matured sexual women ready to take on my cock exclusively in their ass. No complicating things. The sexual activities on the menu are clear.
I too like missionary for the same reason as your husband. With my FWBs that like ATM, my favorite position includes getting her legs up on the couch, fucking her, then pulling out and going straight to her mouth. Another good one is having her lie with her back upside down, head on the floor, ass up. I fuck her gaping hole looking down on her. Her face and hole directly in my line of sight. When I'm ready I pull out and straddle her so she can taste my ass juice covered cock. One thing I've tried a few times with an FWB that I can't get enough of is having her sit on a high bar stool. Then using the swivel to turn her head towards my cock for a suck break. I even make it into a game. I'll turn her around, tell her to sniff, then go onto fucking again. By the time I tell her to suck, she's horny and ready to savor all the ass juice/cum/cock. Nothing compares to ass sex.
