After we woke up, it was hard for me to not act weird at breakfast with Paul and their kids, but I think I had a passable performance. I just had to try as hard as I could not to think about the fact that I had been fucking their mom's tits and ass. Robin actually passed it off better than I did. She came in from her morning jog wearing a jog bra and spandex shorts, and they did not exactly look bad on her 36-year-old body. I mean, I had just seen her naked, but she looked even better with her tits crushed up against her body in the jog bra, creating some damn fine cleavage, and her ass and legs looked fantastic. She was all sweaty, and as she came in, she told Paul she needed a shower.
"My ass got a real workout," she joked, the simple double entendre giving me a woody all by itself.
Later, she told Paul that she needed to show me some science stuff in the museum in town. He shrugged and we went off. She was now wearing a cute yellow summer dress that clung to her body and I wasn't all that sure how much underwear she was wearing. Her nipples stuck out precariously from the dress' fabric.
When we were safely in the car, I asked what was up, but she still wouldn't tell me, just smiling and telling me to hold my horses. After about half an hour's ride, we stopped in the driveway of a house I didn't recognize. But when the door opened, I saw the present she had mentioned to me the night before, and it was already unwrapped. Alicia was standing in the doorway, buck-naked. She looked pretty good too—she had lost a little weight, but none of it came from her tits, so she now looked like a fit, voluptuous hottie—in shape but with her big D-cup tits, enormous nipples standing erect. If anything, those tits had once again grown in my absence. Was she trending towards a double D? They were simply giant—leviathans of the tit world!
"Hi there—I hope you're ready for another reunion," she said smiling, and waved us in.
I obviously was dumfounded, although I suppose I should have guessed what was up. I didn't know what to do, so Alicia led the way, slipping her hand down my pants and grabbing onto my quickly-stiffening dick.
"This way, big boy!" Her considerable breasts bounced as she walked down the hall. Robin's sly smile from the morning had by now enlarged to a huge grin. She was tweaking her own nipples as she walked, and started pulling off her sun dress on the way. We got to a spare room that was cluttered with a lot of random junk, including an open sofa bed, and they both started undressing me.
Clearly, I had questions, and they answered me before I asked.
"We both enjoyed our experience together last time," Alicia said, "and a couple years ago I moved in town here. So for the last two years now, Robin and I have been fucking the shit out of each other a few times a week while our husbands work. We've both gotten to be pretty expert strap-on lovers, but we couldn't pass up a chance at a real cock."
"For my part," she continued, "I want to see that massive beast of yours fuck her virgin ass—or at least it's a virgin to a real cock, that is."
Robin's face turned red.
"What—no, you didn't!" Alicia exclaimed.
"I know, I know...but I couldn't wait," Robin said. "I'm sorry. You'll just have to take it out on my ass—she's the one who made the decision for me!"
"Well, I guess I'll just have to watch your second ass-fuck instead of the first," Alicia said with a grin. "But don't think I won't get you back for this! In the straps you go," she said, and pulled out a set of leather manacles from a drawer, where I could see a bunch of other sex toys.
Holy shit, this was big time! I just couldn't believe demure, quiet Robin had turned into such a perv!
Robin meekly put out her arms, and Alicia strapped them down to either side of an end table. Robin was now kneeling down with her chest on the table, her exceptional ass in the air.
"Alright John, the two of us are going to torture that asshole like there's no tomorrow," she ordered. "Of course, first you have to take those clothes off."
I was never so happy to follow orders.
She pulled open the drawer again and pulled out a ping pong paddle, which she handed to me. Seeing my questioning glance, she explained that the room was her scrapbooking room. She kept all the sex toys in a drawer that Ted thought was scrapbooking supplies. He hated the whole scrapbooking thing, so he avoided the room like the plague, which allowed her to have total freedom in here.
"Now-- whip her fucking ass!" she said, with an honestly shocking amount of seemingly malice—or was it glee?
I looked at Robin's fine naked ass, and took aim. I smacked her full on, and she yelped in pain. "That's it! Fucking do it again!"
I did—several times. Robin's ass was soon burning red, and she twitched uncontrollably every few seconds. But after each swat, she whispered, "Please master, can I have some more?"
This was some crazy sub/dom relationship they had going here. I couldn't believe it. Who gets this lucky?
Alicia, meanwhile, was strapping on a huge silver dildo. It put my own endowment to shame; it was at least 10 inches long and thicker than me. She handed me a black dildo that was shorter, but even thicker than that. I mean honestly, did they actually fit these things inside of themselves?
"Stick this in the bitch's cunt," she said.
I did as I was told—this little 5'4" fury was getting to be the boss of even me! I pushed the black dildo up to the lips of Robin's dripping cunt, and pressed in. It went in easily, despite its girth, and soon its plastic balls were up against her lips. When they said they had been practicing, they meant it; I couldn't believe Robin's cunt could take this monster, it was three inches across.
Alicia moved around to Robin's face and shoved the silver dildo into her mouth. "Suck it, bitch," she said. Slowly, amazingly, Robin started to first mouth, then swallow the huge plastic cock, finally taking the whole goddamn thing down her throat. No wonder she could deepthroat my cock now—look at what she was practicing on! "That's my whore, that's my good fucking whore," Alicia said. "What a little fucking married slut you are."
