Use the ring again, obviously.

It was a Saturday now, and your mother had planned on making it a special ‘you and her’ day, with all that entailed. It hadn’t taken much to make it happen, just subtly working to set your sisters and your father with plans for this day, leaving all of them gone until Sunday on various trips and errands. With just you and her there together all day, you knew that was going to mean some really amazing sex.

But you had a plan, even if you were still a little scared about using the ring again. Taking it out of its hiding place that morning, you used it once again to swap with your mother. Suddenly, you were in her room, standing in front of a mirror. The first thing you saw while in your mom’s body was her reflection, and your eyes widened as you saw what she was wearing. Instead of her usual weekend casual clothes, your mom had put on some lacy lingerie, a bright red teddy that showed off her ample cleavage paired with skimpy underwear that let her butt really stand out.

It made you excited to think that your mother had probably worn this for your father a number of times, but now she had picked it out to wear just for you. Brief flashes of what you now knew she had planned for the day ran through your head, and they were intoxicatingly erotic. But you shook your head. Those sounded great, but you had a mission to handle first.

The first ‘encounter’ your mom had planned had been surprising you in your room in these sexy clothes, so you decided to take advantage of that. You sauntered through the house, feeling a powerful buzz of sexual power through your feminine body with every step, and entered your room without knocking. James was sitting on his bed, on his phone, but he set that down the moment he noticed you opening the door. Any shock on his face was quickly replaced by rapt attention. “Mom...” he breathed, looking at you like you were a piece of art.

His stare only made you feel more confident, and you smiled at him, your son, as you walked closer. “Do you like Mommy’s clothes?” you asked, though you knew it was obvious he did. Still, the nod of his head at your question sent a thrill through you. “Good, Mommy picked them out just for you,” you told him, as you walked closer and reaching down to his pants, briefly cupping his rock-hard bulge, before moving to his zipper to start undressing him. “We’ve got a special day together, just you and me, and I thought we could spend it having fun.” Once his pants were fully unzipped, James moved into action, quickly undressing himself until he sat on his bed, naked before you. Looking at him, you felt a swell of arousal, excited for what was going to come next.

Leaving the clothes on, only moving the panties you were wearing a bit out of the way so he could get inside you, you pinned your son onto his bed and started riding him. After a week as a man, being filled again felt so fulfilling. The sex felt perfect, but then your original plan worked its way through your hazy mind and you made eye contact with you son. “Your Mommy loves riding her son’s cock...” you moaned, “...because she’s a filthy slut.” That last word was one your mom would normally never call herself, but you made yourself say it anyway, even as all of your mom’s instincts were telling you not to. The second you said the word, you felt your son’s cock thrum inside you. “You like that? Please, call me a slut.”

You could see the stunned surprise on your son’s face, but he didn’t waste any time in doing as you asked. “Look at you,” he said, out of breath from the pleasure he was feeling under you. “Dressed up like that, coming into your son’s room. You probably bought that for Dad, but you don’t want him anymore, do you? No, you want me. It’s because you’re a filthy slut, a wanton whore, and you would gladly suck off a hobo to get your fix.”

That was more intense than you were expecting, and your body’s first instinct was anger, to tell your son that such words were utterly inappropriate. But you were in control, and kept riding him, managing to just say, “Yes, you’re right!” before he came inside you, filling you with his spunk. You got up, careful not to get any of his leaking cum on your nice clothes, before quickly heading to a bathroom to clean up.

“You’re sure you’re okay with all that, Mom?” your son asked from the other room, sounding genuinely concerned. “I know you told me before to avoid using words like that, and I don’t want to make you uncomfortable just to help myself.” The concern your son was showing for you was almost enough to make you cry.

But it also gave you the opening to really get your plan in place. You told him as you reentered his bedroom, “Well, I’d never been called things like that before, not in a way that made me feel good, so I reacted badly. But the more I thought about it, the more I liked the idea of you taking control, and demeaning me like that. I’d love it if you did it more from now on, it really turned me on.” That clearly made James happy, but then you excused yourself so you could go and get the ring. What you’d done wouldn’t affect your Mom’s behavior unless you switched back, so you were suddenly in your original body again, feeling spent where it counted.

Your mother entered the room, looking at you with love and lust in equal measure. “That was just the first course of the day,” she told you. “And I want you to call me anything you want, whenever you want.” That certainly got you excited, but you couldn’t help but fiddle with the ring. Should you enjoy this day as yourself, or as your Mom?
