While preparing dinner, I heard yelps and moans of pleasure every few minutes, drifting down from our bedroom upstairs. Kate usually adopted a more loving persona with her mother when it was just the two of them, in contrast to the dominating attitude she employed when she and I were double-teaming Sue. I looked forward to hearing about their activities.
Over dinner, Sue and Kate took turns filling me in on what I'd missed. Kate had donned a white tank top that showed off her ample breasts, while Sue was wearing a faded T-shirt she had gotten from running a 5K years ago. Sue's attire wasn't particularly sexy, but those tits were hard to hide. I definitely married in to the right family.
"Slut, tell my husband about the reward you're getting later for making me cum so hard just now."
Sue blushed slightly, finishing up a mouthful of pasta before responding.
"I tried really hard to make Kate... Mistress, I mean... to make Mistress cum while she rode my face. She said she had a really great orgasm."
"She's being modest," my wife explained before turning back to her mother. "Tell him about the new thing you did this time."
"While Mistress was riding my face with her delicious cunt, I... I stuck my thumb up her ass. I just couldn't help it."
"She made me cum so fucking hard I can't even describe it. And your reward, pet?" I anxiously awaited Sue's answer to my wife's question. Sue looked down at her plate, looking bashful. "I told her to pick anything," Kate explained to me while we waited for her answer. "What did you pick, pet?"
"I want to wear the new toy you got. I want to use it to please my mistress."
My cock twitched in its half-hard state. I definitely wasn't opposed to watching my wife get fucked with the monster strapon she had gotten earlier.
"She wants to pretend like she's in charge for a little while. And I guess she's earned it, with how good she made me feel. But..."
I raised an eyebrow toward my wife, while Sue shot her a look of apprehension.
"... there is also the issue of your punishment, slut-mommy." Sue looked confused, trying to formulate a question.
"But... Mistress, I... punishment? I made you feel good."
"And you did it by touching one of my holes without asking permission. I can't just let that go, can I?"
Sue looked down at her plate, defeated.
"No, Mistress. I should be punished for that."
My wife and I shared a mischievous grin across the table.

After dinner, Kate handled the kitchen cleanup while I went back upstairs with Sue.
"Grab the cuffs from the dresser and put her on her back on the bed," my wife instructed me before I headed up. "I'll be up shortly so we can administer her punishment." Sue looked both scared and excited upon hearing this.
As we ascended the stairs, I took in the wonderful sight of my mother-in-law's plump ass. The ass I had already fucked once today and would fuck again later. I couldn't resist taking advantage of the situation. I reached up and grabbed her ass with both hands, giving it a hard squeeze and forcing her to stop where she was. She bent at the waist, placing her hands on the top landing. She seemed to know exactly what I wanted.
I peeled her yoga pants down, exposing her asshole, and quickly pressed my face into her. My tongue pushed hard into her tight hole and caused her to moan loudly. I tongue-fucked her asshole for about a minute before managing to pull myself away and get her pants back up. I knew I needed to have Sue in position by the time Kate got upstairs.
When we got to the doorway of the bedroom I turned Sue around and kissed her deeply, pressing her against the doorframe. She was reluctant to open her lips to my tongue at first, given that it had so recently been up her ass, but she gave in and returned the kiss passionately. We broke the kiss and stared into each other's eyes, both breathing heavily.
"Thank you for earlier. Trying to take it easy on me," Sue said as she looked up at me.
"I just figured you needed a little break."
"You're always so sweet to me. Kate, too, when we're alone. But when you two are together, she can be a real demon. Speaking of... do you know what my punishment is going to be?" Sue looked concerned as she asked the question.
"I really don't know what she has planned. But hey, you get to pay her back after as your reward."
Sue smiled and licked her lips in response to this. I couldn't wait to see her fuck my wife with the big strapon.
"We'd better get you in position, Sue. I mean, mommy-slut." I smirked at her as she removed her t-shirt and pants. She pressed her naked body against me, giving me one more deep kiss, before turning and climbing on to the bed.
"On my back, she said?"
"On your back, slut. I'll get the cuffs."
Kate and I occasionally used the handcuffs on each other, but they were primarily used when we played with Sue. I removed them from the top dresser drawer and moved to put them in place. One pair per wrist, I cuffed my mother-in-law to the bed and awaited the arrival of my wife.
Kate entered the room with the video camera. I was instantly intrigued. We had recorded ourselves in the bedroom before, but never with her mother. This was a big development.
A look of dread overtook my helpless, handcuffed mother-in-law.
"Please... no video... don't record me. I'm begging you." Sue's lips quivered in fear at the idea of having her degradation preserved on video. She looked to me desperately, looking for a sign that I might step in and change Kate's mind. But honestly, I loved the idea.
"For our eyes only, right babe?" I asked my wife. She nodded at me reassuringly as she got the camera adjusted and ready to go.
"Of course. We're the only ones who will ever see this. But I want her to see what she looks like when she's being such a dirty slut for us. I want her to hear what she sounds like when she's begging for cock in her slutty holes. Sound good, mommy? Consider this part of your punishment for misbehaving earlier."
"Yes, mistress..." Sue closed her eyes and took a deep breath, mentally preparing for the humiliation that she was expecting to receive. I stood lightly stroking my cock, enjoying the visual. Kate approached me with the camera in one hand, reaching out to give my dick a few soft strokes.
"Get this really hard while I'm doing the introduction. We'll need it soon."
I liked the sound of that.
"Okay, pet, we're rolling," said Kate, turning to address her mom. "Look at the camera. Look at me."
Sue kept her eyes closed firmly for a few seconds, earning her a quick slap from Kate. Sue opened her eyes, looking hurt, gazing tentatively up at my wife.
