Recap:
This is part three of a series. I recommend you read parts 1 and 2 first, as they will help you to understand how the mother ended up where she is now; if you've already read the first two parts and can't remember the basic plot or just want to start here on part 3... here is a very brief summary of the story so far.
"Pet Mommy": Creating a Mommy-Slut:
A mother learns that her son fantasizes about fucking her and, realizing how much he resembles her deceased dominant husband, she decides to make his fantasy into a reality... by seducing her son and becoming his submissive Pet Mommy.
"Pet Mommy": DP Mommy Slut!
The mother's dominant son makes another fantasy come true... her first double penetration. He also insists that she seduce her daughter and give her to him as a present for his upcoming high school graduation. That seduction is what part three will focus on.

I love Michael, my son.
I love how he's become the man of the household, I love that he always knows what I need sexually.
I love that he's discovered both my long-lost submissive side and his own newly-discovered dominant side.
I love that he uses all three of my holes whenever he wishes, and recently he's even begun sharing me with his best friend Frederick, and that's been amazing.
I love the taste of my son's cum in my mouth, the feel of his cum exploding in my pussy and even the embarrassment of his cum leaking out of my ass.
I love that he is my Master and that I am his submissive.
Yet, it's one thing to make a promise while in the throes of passion, but it's quite another to attempt to fulfill said promise once clarity hits; which leads to his latest expectation of me... to seduce his sister, my daughter, which seems an impossible task to fulfill.
**********
Two days before Crystal was to return home for Michael's high school graduation, he asked, while his cock was pounding my ass slowly, his cum still dripping out of my cunt from his last load just a few minutes ago, for me to explain what my seduction plan was.
"I-I-I don't know," I stammered, distracted by how good his cock felt in my ass, not to mention I had no feasible idea of how to turn such an impossibility into a possibility.
His cock lodged deep in my ass, he stopped fucking me as he pointed out, disappointed by my insufficient answer, "Mother, you've had almost a week to plan. She's going to be here in two nights. I expect her to be on her knees and ready to please me by Saturday evening, is that clear?"
He pulled out and slammed into my ass, hard. I screamed, "Buuuuuuuuut hooooooooow?"
"You want my help?" he asked.
"Of course, Master," I purred, "I feel completely helpless about this," trying desperately to get him to assist me in this crazy conquest he had in mind. Oddly, when I was horny, which was often, the idea of seducing my daughter was quite the turn-on; I'd already crossed the line in every way possible with my son, so doing it a second time with my daughter didn't seem as bad as the on again off again guilt I'd felt while I was seducing him. Accepting yourself for who you are and setting aside society's attitudes about incest was very liberating. So was doing research on incest and realizing three things:
1. Historically, it has been quite common.
2. Although seldom revealed openly, incest is much more common than people let on... once you dig deeper into the underbelly of society's unrealistic expectations.
3. The more I accepted the first two items, the easier it became to convince myself that there was no better way to show how much I loved my son than to give myself to him unconditionally: mind, body and soul. After all, those are the traditional expectations of a woman when she marries a man, and that was exactly what I had done for my husband for those several years before his unexpected death. In the most simplistic terms, Michael had recently stepped in for his father as head of the household, and now received the exact same benefits my husband used to enjoy. Plus, as much as I loved my husband, god bless his soul, I now loved my son even more.
"On Friday, take her shopping somewhere to get her a new dress for the graduation ceremony, and then suggest going to a lingerie store as well, telling her you have a new man in your life," he began.
"Okay," I moaned, his cock pumping in my ass a constant distraction. "I'm not sure that will be enough."
"Well, if she's as big of a slut as her mother it may be, but I thought while you were bonding with her, I could do some reconnaissance on her computer," he continued.
"Oooooh," I moaned, thinking this idea seemed like a good start. Such an approach had been invaluable when I'd first explored the idea of seducing Michael.
"If the eyes are the gateway into the soul of a person, their hard drive is the gateway into their kinks," he concluded, something that was pretty hard to disagree with.
On the computer you could research secret kinks, read stories based on such interests, have chats with people with similar kinks and, of course, watch every type of porn imaginable, many subsets of which I never knew existed. (Did you know there's a cartoon porn site which depicts many of the cartoon characters we grew up watching? I sure hadn't.) Since seducing my son, I've watched online incest porn and read lots of incest stories, each story making my guilt fade away a bit more. Since receiving Michael's order for me to seduce Crystal, I've been reading mother-daughter incest stories not only because they're hot, but also trying to research ideas I can use to come up with a game plan. Yet, incest stories are exactly that, stories, and making such a seduction into a reality was way more complex than putting pen to paper. (Or okay, these days putting keyboard to hard drive.)
"That's a good idea," I moaned, my orgasm starting to build, my greatest orgasms coming from anal sex (strange but true).
"And just to add a little motivation to your task," he announced, surprising me by pulling out of me, he loved coming in my ass.
"Whaaaat?" I whimpered, frustrated that he'd pulled out with me so close to orgasm.
He circled around and shoved his pulsing, stiff cock in my mouth and began fucking my mouth as he explained, "You aren't allowed to come until your task is completed."
My eyes went wide; the gravity of his expectation and the consequences of failure were now clear. I would have responded with pleas for mercy, but his cock was fucking my mouth, his balls spanking my chin with each thrust. I usually loved his aggressive need to come approach, but with my orgasm so close and suddenly knowing I was no longer allowed
any
, I was super annoyed.
He continued, "You can still get your daily dose of my cum with blow jobs, but you aren't allowed to
cooooome
."
His sweet white stuff exploded in my mouth and I focused on swallowing it all like I'd been trained to do, wasting cum was way worse than wasting booze. He slowed down as I milked his cock for every last trace of his addicting sperm.
Finally he pulled out and continued the conversation as if it hadn't been interrupted by his shooting his load in his mother's mouth, "Is that understand, Pet Mommy?"
"Yes," I answered, stretching my mouth after the quick pounding it had just taken.
"You don't like the idea?" he asked, catching my disappointed tone.
"May I speak honestly?" I asked, looking up at him.
"Of course," he shrugged, his cock beginning to shrink before me. It really is one of the really great wonders of the world, the beauty of a cock growing to an aroused state or a just-shot-its-load-cock slowly returning into sexual hibernation.
"I'm very close right now, Master," I explained, praying for sexual release.
"All the better for you to understand the full importance of my expectations of you. I want Crystal as my graduation present," he answered.
"I just don't know if I can do it," I admitted.
"I know you can, Mom," he said, putting his cock back in my mouth. I swirled my tongue around, giving his cock a quick wash before he pulled out and cautioned, "Now, no more of this defeatist mindset, is that understood?"
"Yes, I understand," I answered, adding jokingly, "May I go and take a cold shower?"
"Does that work for women?" he asked with a chuckle.
Standing up, I answered, "I'm about to find out."
Although the coldness didn't extinguish my burning flame entirely, it did cool down the fire inside me sufficiently to let me think straight.
The next two days were torture as I tried to resist the temptation to come, especially when each morning's wake up and evening's bedtime included my swallowing a load of Michael's cum. I wanted him in my cunt and ass, I wanted to be fucked, pounded, and used. Yet each time, Michael only reminded me of the task at hand.
When not being used as a cum receptacle, or working (selling real estate), I was reading sex stories, chatting with online mothers who had seduced their daughters (if they really were mothers, there are a surprising number of men out there masquerading as women), and trying to formulate a plan that had a chance of working. In the end, a mixture of flattery, intimate contact and open conversations seemed to be the key... and of course, booze. The major problem was that I was on a very limited timeline.
The morning of the day Crystal was to arrive, Michael deposited a load down my belly for breakfast and asked, "So, is my pet excited for her new task?"
"I'm excited to be allowed to come and to make you happy," I answered.
"You don't want to seduce your daughter?" he asked, surprised by this possibility.
"I'm more scared than anything," I answered. "Even though I knew it was technically wrong when I seduced you, I knew it was your fantasy."
"That it was," he smiled, his beautiful cock beginning to shrink.
"But with Crystal... first of all, girls are different," I began.
"Oh, I beg to differ," he quipped, "you're usually hornier than I am," tracing my willing lips with his cock.
"Okay, but I'm the exception," I smiled back, licking the bottom of his cock.
"Well, Crystal looks like you, has the same body type as you, and the same quirky personality as you," Michael pointed out.
"So if Mommy is an incest slut, then Crystal must be one slut too?" I quipped, moving my tongue to his balls, something I'd never done to him before.
"It's a theory," he moaned, as I took one of his balls in my mouth.
