In the few weeks since I'd taken Linda's anal virginity, Lily and I had gotten together with Charles and Linda a couple of times, both together and separately. One Saturday, I took my son out of town to see my parents. We told them Lily had to work on a big project, but she was actually in our bedroom most of that weekend, letting Charles fuck her in the ass several times. When I returned, Lily and I made love as we watched the video of it together and we both came so hard that we collapsed into a sweaty sticky mess on the bed. I awoke a few hours later and the TV and all the lights were still on. Lily didn't even stir as I turned it all off and rejoined her in the bed.
Charles finally got to take Linda anally a week or so later when they came to our house and had a four-way tryst much like the first time, except Charles and I ended the evening anally fucking our own wives as they knelt side-by-side on the bed. Charles came over the next day with a bottle of very old and expensive single-malt scotch as a thank-you present.
Presidents Day weekend, Charles and Linda decided to take the long weekend for a getaway. Since Lily had agreed to accompany our son on a trip to some video game convention he wanted to attend, I was left to my own devices from Friday evening until Monday afternoon. To say it was quiet would be an understatement. Nothing at all was going on until fairly late on Saturday afternoon when, while I was checking my email, I heard the video system kick in. I figured Abby was up to something. Part of me (mostly my dick) hoped that she was up to some fun with her boyfriend Chris -- possibly even including her pal Melissa like they did over New Year's. I loved jerking off to that video. No such luck, however. It was merely Abby returning some of her mother's panties to her lingerie drawer and some other stuff to the closet, which was out of view of the cameras.
It was just after sunset when I got a call from Abby. She told me she had heard a noise and wanted me to investigate. When I arrived, Abby was dressed in tight jeans and a midriff-baring, very tight t-shirt. Her flame-red hair was braided into pigtails. She looked a little nervous. When I asked where she had heard the noise, she led me to her parents' bedroom.
When I asked what kind of noise it was, she told me, "It sounded like my mom, moaning like crazy while you fucked her from behind, because that's exactly what it was." she told me. Oddly though, she didn't really seem angry. "A few weeks ago, I forgot my flute and came home during lunch hour to pick it up before we had band practice after school. When I walked in the door, I heard Mommy groaning. I was scared for a second, but then I heard her say, 'Fuck me, baby' in the middle of all that moaning, so I was curious. I thought that she and Daddy might be 'doing it' but Daddy's car wasn't here so I had to see who could possibly be fucking my mother."
"The bedroom door wasn't quite shut," Abby continued. "When I peeked in, there was mom with her butt in the air and her face down on the mattress with you fucking the shit out of her. She was pounding the mattress, clutching the sheets and begging you to fuck her harder. I will say, Mr. B., it must've been good. She's not usually that loud with Daddy."
I suppose I looked a little surprised, because Abby said, "I hear them all the time, especially lately. It's a little weird to hear your parents fucking, but anymore it really turns me on. I finger my pussy and try to time it so I come with them. Some nights they'll go two or three times."
"That's a little more information than I need to hear, Abby," I scolded, trying to maintain some adult demeanor.
"Too much information is watching some guy fuck your mother, pull out of her, tear off a condom and shoot spunk all over her back and down her ass," Abby countered. "Are you going to deny it or even try to explain it?"
Abby had to be telling the truth. She described the action exactly as it had happened, and I knew that she had seen me cum after taking Linda's anal virginity. I began to wonder what was this girl up to.
"It's kind of hard to deny, and I don't know that I necessarily owe you much explanation, Abby," I said calmly. "About all I'll say is that I'm sorry you had to witness it."
"Well, I guess I could always have my Daddy ask you explain it," she said slyly, "or maybe you could explain it to your wife?"
I was beginning to comprehend what Abby wanted from this conversation. Blackmail is an ugly thing, even though it really wouldn't have worked in this case. After all, Charles knew I was fucking Linda. Lily knew I was fucking Linda. And we all knew that Charles was fucking Lily. Abby didn't know any of that though. She had no clue that the four of us had been swapping and sharing sexual adventures together since October, and I wasn't going to tell her if I could help it. If she thought seeing me have sex with her mother was too much information, where along the scale would be the idea that her father and I both enjoyed licking the other's cum out of one of the ladies' freshly fucked pussies?
I quickly decided to play dumb and nervous. "So what do you want from me?" I asked cautiously.
