After breakfast, I felt more than a little horny, to put it mildly, as did Sherry, and the wink that she gave me indicated plenty of her agenda, if nothing else. I took Brittany by the hand and led her to the kitchen counter, where I parted her cheeks and put some butter on...and in...her asshole as well as on my dick. A few strokes into her bottom with my fingers, and I had her fully opened up for at least the tip of my cock. A few more thrusts, and then I had half my prick in her butt now, much to Brit's evident delight as she moved her hips to take me further inside her. I gripped her ass and hips to drive deeper, which only excited Brit even more as I pounded her booty good and hard now.
"Oh, God, Master! That's everything that we dreamed of when we thought of this!" Brit confessed as I continued sodomizing her.
Meanwhile, Sherry had Rich right where she wanted him, too, with her strap-on and thigh harness to pump in and out of his bunghole. He was being pegged rougher by the second, but at least she lubed him up before she started buggering him. Fortunately for Rich, the presence of his prostate, which Sherry soon hit as she bottomed out inside his asshole, was more than enough to get him very warmed up to the idea of having a woman take his butt that way.
"Oh, damn, that's sexy as hell, watching Sherry peg Rich like that! How does it feel, by the way, to fuck my ass?" Brit asked me, as I reveled in the hot, tight bottom underneath me.
"It feels every bit as great as it did yesterday, babe. There is a lot of heat and friction there, inside your fine, tight booty. You certainly know how to work it, too," I praised Brit, my nerdy, submissive strawberry-blonde butt-slut.
Brit blushed just a little as she heard my compliments, now really using her hips to get more of my cock inside her asshole. I had to admit that she was the main attraction of this deal, though Rich was nothing to sneeze at, either. Her smooth, sweet ass was her best feature, though I was partial to her legs as well, not to mention the glasses that she wore and her pixie cut hair-style...they just screamed geek or nerd or both. The more I got to know her, the more convinced I was that this wasn't a superficial image or stereotype...She was obviously the brains of her marriage (though Rich was no idiot himself), and slightly more open-minded than her sensible, but more cautious husband.
"Should I grow my hair out, so you can pull it while you fuck my ass?" Brit wondered as I plundered her anally.
"No, baby, I like it how it is. It fits you down to a tee, how nerdy and smart you are," I grinned as I continued to ram her lovely bottom with my stiff dick.
By now, Sherry had Rich penned pretty good, too. Her strap-on seemed to find new depths in him, or so it sounded as she kept probing him with her plastic prick. He certainly didn't seem to be complaining, judging by his groans and moans of pleasure. Then again, if he was willing to let a man fuck his ass, why would he object to a woman doing it, especially a woman as sexy as Sherry? My ex-girlfriend knew how to maximize the pleasure in a sexual encounter, as she demonstrated by stroking Rich's cock while she pegged him. For my part, I started rubbing Brit's clit while I sodomized her, making it even harder for her to resist cumming during my invasion of her booty. Her moans joined her husband's in getting louder by the second, so much so that I wondered if she would disturb any neighbors sleeping in on a lazy Sunday.
