When Sue left for church, the idea had been for me and Kate to get started planning a gangbang for her. However, we got about 15 minutes into discussing the logistics of it all before we were too horny to do more. Kate ended up on her knees, sucking me back to a full erection not long after I had sent a load deep into her mother's pussy.
We must have lost track of time. Kate was riding my cock on the couch when we heard the door open again. Sue was already back. Kate and I had been engaged in foreplay and fucking for over an hour.
"Perfect timing, slut!" Kate yelled as she bounced on my stiff cock. "Get in here and help us finish up."
Sue turned the corner from the front hallway to see what we were up to. Seeing both of us naked, in the midst of wild fucking, Sue broke into a wide smile. I was surprised to see her look so excited at being surprised this way. Sundays were, after all, usually her "off day" from us.
Sue approached the couch and sank to her knees. She eagerly moved in close to where her daughter's pussy was wrapped around my dick. She licked her lips wantonly. And to think that only a short time ago, she had been sitting in church surrounded by pious, innocent, straight-laced women who had no idea what a nasty cocksucker she really was. Sue's dual nature was incredibly sexy to me, knowing that she put on one face to the public and an entirely different one at home with us.
"Mmm mommy, lick my asshole while my husband fucks me. I need it right now."
"Yes, mistress." Sue didn't hesitate at all. She obediently moved behind her daughter's fat, jiggling ass as she plunged right in with her tongue.
"Oh, fuck! That's a good mommy slut! Get in there deep. Get your fucking tongue in there."
Sue obliged, ravenously forcing her tongue deep into my wife's ass and causing her to moan obscenely.
"Oh fuck yes, that's my good mommy slut. Just back from church and already eating your daughter's asshole while she rides cock. Such a nasty mommy whore."
"Mmmhmm..." was all Sue could manage in response.
"No bread and wine for you right now, but we have something you like better. You can eat some ass and then wash it down with another load from this big cock. Is that what you want, whore?"
"Yes, Kate, oh yes please. It's exactly what I need."
I was about to bust with all of this stimulation, and Kate could feel it.
"Someone's getting too excited. Are you ready to blow, babe?"
"Fuck yes. I'm gonna fucking cum."
"Do it in Mommy's mouth," Kate ordered as she climbed off of me, freeing my cock from her tight, wet pussy. It stood erect and glistening with her juices for a moment before Sue eagerly swallowed it whole.
I didn't last long in Sue's throat before I started shooting a big load of cum. Like the practiced slut she was, Sue had no trouble gulping it down. Once my orgasm subsided, Sue gave me a big smile. From my right side on the couch, Kate also smiled lovingly at both of us, appreciating the beauty of what we had all just experienced. It had been a whirlwind of pleasure, but we knew that there would be plenty more to come.
"So, Mother," Kate said with a smirk. "Does this mean you're officially forfeiting your day off?"
"Yes... I... I don't know what's gotten into me today. I just need to... to..."
Sue trailed off, starting to blush slightly, before continuing.
"... to suck... and fuck... and swallow cum... and eat pussy and ass... I think I'm just..."
"A filthy cockwhore?" Kate suggested.
"Exactly," Sue nodded in agreement as she smacked her lips, licking away some cum that had escaped her mouth.
