[Where were we? Chapter 1 ended with Sheila's mom grinding her soppy snatch on Buddy's face at Marci's command.]
"But... how..." Sheila had so many questions, but she was struggling to grasp what was happening. Buddy? And her mom? Why were they behaving so lewdly? What had Marci done to them? Sure, Marci was cute as fuck, but it looked like she had some kind of controlling power over them.
"It's really very simple," Marci answered. "Most people are naturally submissive and, given the right motivation, they become quite obedient." She smiled as Sheila watched her mother's wanton behavior, wide-eyed in admiration. "You can get people to do pretty much anything you want once you've figured them out. It always takes a combination of rewards and punishment, and everyone is different. The trick is not only finding ones that work, but also balancing them. For example, your mother is motivated primarily by sexual pleasure and humiliation, so I can punish her by denying sexual relief. Also, pain works as a deterrent with her." She nodded soberly. "But you have to be careful with pain. Some people get addicted to it. And then it becomes a reward instead of punishment." She smiled and tilted head, gesturing toward the incestuous coupling. "It's pretty clear that pain works on your husband! He knuckled under pretty quick!" She chuckled. "But I also already knew that he was a slut for sex, so he wasn't a hard nut to crack. Most men are like that, at least the highly sexed ones. Their brains are in their most vulnerable spot." She laughed.
"So, what?" asked Sheila, dubiously, "Am I supposed to kick my husband in the balls every time he gets out of line?"
Marci laughed again. It was a really pleasant, almost musical sound. "No... No, not at all... Well, you might need to occasionally." She allowed, smiling brightly. "The thing with your husband... well, I think he's a major masturbator. I'll bet he used to do it a lot when he was away from home all the time. It would only be natural. But now he's always home and you're always there. So you're a constant stimulant, but also a deterrent. Being around you is a turn-on, but he can't just fuck you whenever he wants, can he? And he can't masturbate with you around, either. So he's probably pretty frustrated. He probably needs sex more than once a day, I'd guess at least ten or twelve times a week. You need to take control of his masturbation if you're going to control him."
This was beginning to make sense to Sheila. Meanwhile, Betty's moans were getting louder and Buddy's panting was audible as well.
Marci continued, "If you can take charge and especially if you can control his sexual activity, your life is going to be a lot happier."
Sheila nodded. She could see that working with Buddy. "But how do I keep him from masturbating? How do I control that?"
"Well," replied Marci, "the classic way is chastity - you lock up his cock or restrain him in some other way - but, based on what I've seen, I have a better idea." She grinned conspiratorially. "What do you think of turning Buddy into a pet?"
"A pet? You mean, like an animal?"
"Exactly." Marci nodded. "Like a pet dog, for instance - you saw how he humped Betty's leg... Do you think you'd enjoy keeping him as a pet?"
Sheila frowned pensively. "Um... I don't know, really."
Marci said, "I can see this is all new to you... Imagine if he couldn't talk and he was always obedient to simple commands. He would be very affectionate, but completely under your control. So absolutely no sex with you except exactly when and how you want."
"Sure, that sounds great! But what about the masturbation? You said he needed..."
"Yes, well, you can easily control that. He wants to masturbate all the time - several times a day if he could - that's not going to change. But he would always be naked, so you would know what's going on with his cock. And he wouldn't be able to use his hands - he's not human anymore, remember?" Sheila nodded. "So he would have to hump things, like dogs do. So you would only have to control the when and where. He could hump on you, if you want, like he did your mother. Or he can have a toy to fuck. I've seen some very cute K-9 sex toys... I think he would enjoy fucking one of those. I'm sure he'd hump pretty much anything - seems like the type." She grinned.
"Wow! It sounds so weird..."
"Well, chastity is the other method. You have to lock up his cock - there are special cages designed for this - and then you can release him and milk him as a special reward. I have friends who have had great success with chastity. I just don't think that's the best way for Buddy. No, I definitely think pet training is the way to go. Why, even his name sounds like a puppy-dog's." She laughed. Sheila looked uncertain.
"Listen, it's not as unusual as you might think," Marci continued. "I know several couples who are into the lifestyle, boy pets and girl pets too. There's even a local 'kennel club' with monthly pet shows." "Those are fun!" she grinned. She cocked an eyebrow knowingly at Sheila. "Maybe you could attend one of their... Wait a minute! I think I have some pictures here somewhere..."
Sheila turned to watch her moaning mother pleasure herself on her husband's face while Marci took out her phone. The squishy sounds of Betty's sopping sex and the slurping and panting noises beneath her were quite arousing. Buddy was clearly happy as a pig in shit: his hands were grasping his mother-in-law's gyrating hips to ensure maximum contact with his busy mouth, and his cock was at full mast again, its thick outline visible in his wet shorts, soaked by his recent voluminous spend.
He is a horny old dog! she mused.
"Here you go," enthused Marci, handing Sheila her phone. "Take a look at some of these."
Oh my, Sheila thought, surprised at her immediate reaction to the pictures. The first photo showed a woman holding a leash attached to the collar worn by a naked girl on all fours crawling behind her. It was absurd! But it made her pussy tingle. The next showed a naked man with some kind of muzzle on his face. He too was collared and leashed and he had a tail! - a kind of butt-plug shaped to protrude like dog's tail - and he had an erection for all to see! She scrolled some more, and then some more... There must have been fifteen or twenty pictures, some of them at group events, and all of them showing naked men and women portrayed as pets, presumably dogs?, often lewdly displaying their genitals in various stages of obvious arousal. Marci watched her as she scrolled, gratified by her obvious interest.
Meanwhile, Betty had come to the end of her endurance. Three orgasms in quick succession is a lot to take for a 72-year old! She slumped, spent and panting, still sporadically spasming as she tried to dismount, struggling feebly against Buddy's firm grip and relentless tongue. His cock was straining against the wet fabric of his shorts, visibly in need of relief.
"Buddy!" Sheila exclaimed, "Let her go!"
Buddy immediately released the old lady, who clambered off and rose to her feet.
Well, if I'm going to take charge of things, I might as well start now, Sheila decided. "Buddy! Take off those disgusting wet shorts. Right now!" she commanded. Without a glance at her - was he too ashamed to took at his wife? - and without comment, he arched his hips and pulled the shorts and undershorts down and off.
