Marital sex just needs to be varied. If the couple won't do it together, then clearly they will still do it secretly each separately! I think this home variation is acceptable, in any case it is not as extraordinary as entertaining a large group of swingers. My wife and I once invited me to one of these, against her this clip is just sex puritanical family!
When I saw her nipples sticking out through the rings, I knew she was a bitch. And she didn't disappoint me. She's a working girl, even her asshole's winking. It was like I was cumming in her asshole.
