My wife, Kelly, had gone back home to Texas to visit her parents for a week. I was unable to get any time off from work, so I was on my own for the week.

On the second day, Kelly called me at the office to tell me that she had given our good friend Randi a spare key to the house and that Randi would have dinner waiting for me when I got home. My wife knows how I am, and wanted to make sure that I had at least one square meal while she was gone.

When I got home, Randi had a great meal waiting for me, which I really appreciated.

Randi told me Kelly had instructed her that I was to take a shower after dinner and then she was to take me out for some drinks.

I’d been in the shower for about five minutes when I was startled by the glass door opening. There was Randi, completely naked. “I forgot. Kelly told me I’m supposed to join you,” Randi said. I was speechless and unsure what to do as she stepped into the shower. My cock rose at the sight of her beautiful body.

Stroking my cock, Randi reassured me that Kelly wanted this to happen. Then, kneeling down, Randi took my cock into her mouth and sucked it until I shot my load of warm come deep inside her throat.

After leading me to the bed, Randi straddled me and placed her cunt over my face. I ate her tasty snatch until it was my turn to have her warm come deep inside my throat. We sixty-nined until Randi had my cock hard again. I still couldn’t believe that my wonderful wife had sanctioned this.

Randi sat down on my cock and started fucking me. Then we switched places and fucked in both the missionary and doggie-style positions. Randi had my cock and balls soaked and glossy with her come juice.

I thought I was going to faint with sheer excitement when Randi raised her bottom and cried, “I want it in the ass. Fuck me in the ass.”

As I slowly pressed my come-laden cock inside Randi’s beautiful tight ass, she thrust backwards, took my cock all the way inside her, and screamed, “Fuck my ass!”

I’d never been with a woman who loved getting fucked in the ass as much as Randi did. She went absolutely wild, yelling for me to fuck her even harder, telling me how wonderful I felt inside her ass. I could see her hand beneath her, vigorously working away at her clit. She screamed out as she came — to my delight, and, I’m sure, the neighbors’.

Randi took me in for another shower. Then, right there on the bathroom floor, she had me fuck her doggie-style and then in the ass again until she came. Then she took me into the living room. She sat her ass down on my cock and fucked herself while I sucked on her big tits. Randi reached orgasm again, and I again deposited my load of come in her beautiful ass.

I called my wife after Randi left. Kelly was very happy I’d enjoyed her little surprise, and made me describe every exciting detail. Then she told me that some night she wanted to watch me fuck Randi. I’m so excited at this prospect that I’ve already arranged for Randi to come and make dinner the night Kelly returns.
