Absurd Obsession

Highly sexed wife is very very anal and has amazing climaxes with her arse filled and abused. Have shared her backdoor in swing situations several times over the years. Always find it extremely exciting to spread her perfect cheeks and expose her funky bumhole.
So this confession is rather tame but I get turned on thinking of eating her swampy sex whilst she's taking a pornstar sized cock in her hairy pussy and the bull slips one finger up her butt. When he takes it out it's dirty and I suck his large dirty finger as he's making her squirt. He gives me a demeaning grim watching me suck every bit of her poo off his fat finger. Knowing he's going to be plundering her arse and dropping another load in her belly. I got to go have a wank right now.
