Tentatively, Mum undid the cord of her robe. My mouth was dry and I made no effort this time to hide my arousal. She turned away from me as she let th... robe slip from her shoulders. I ordered her to turn around. She did so but her gaze was on the floor. She was wearing a white, lacy bra and matching thong panties. My eyes went down her long legs, covered in fine, tan coloured hold-ups to her feet. Her toenails were painted their usual red and she had put on the red sandals I had given her last. It takes me a minute, but I finally realize that she's not alone. There's someone on top of her and I can't make it out. At first I'm totally pissed, but then I realize that I have a raging hard on in my pants and that I'm really turned on. Who the fuck is fucking my wife?! I get my first glimpse when the comforter slides off a bit. This guy is repositioning to get her legs over his shoulders and the comforter drops down. I see a head of light brown hair and a muscular torso. The skin on. I ordered her to wear a very brief pair of black and pink bike shorts (they exposed the lower part of her ass) and a matching string halter top. That was step one. I drove her to a park on the outskirts of town. ‘It’s a beautiful spot, Mistress,’ my slut said appreciatively. ‘Good, because we’re here to play. Lean over.’ She leaned toward me. ‘Close your eyes.’ I put a blue dog collar around her neck. ‘You may open them again.’ She didn’t know the significance of what I’d done yet. I got out of. As I moved back up Carrie reached for my cock and slipped it into her hot pussy. Having cum earlier, I knew it would take awhile before I was ready to cum again. Carrie talked to me sexually explicit on how to move to satisfy her. This continued for several minutes as she had a few climaxes. Carrie looked at me and said we are going to do something very different as she slipped my cock from her pussy. Carrie reached into her drawer and got a tube out and rolled over and got into the doggy.
