"Okay, baby, just like we practiced, ready?"
My husband swallowed audibly, extremely conscious of the other, more virile man with a possessive hand wrapped around my waist.
"P-please dear," he wavered. "I won't do it again, I swear. Just please don't make me do this."
I frowned and tutted disapprovingly. "Is that how babies talk?"
"I'm not a baby..." He dared to mutter.
I gasped and put a hand to my lips. "You're not?! Do you hear that, Daddy?" I asked, leaning in to my boyfriends chest. His arm tightened around me and my kitty started leaking. "The little guy here says he's not a baby. That means I don't have to do any more of that silly 'boobie' time stuff." I said, referring to the times when I graciously let my poor hubby suckle on my nipples while I stroked the crotch of his fat diapers. I grinned widely as he let out a long, pathetic whine.
"Wait, wait, no please. I'll do it. I'll do it, please let me do it!"
As pathetic as it was, we both knew it was the last shred of sexual activity he had with me and I knew he was desperate beyond belief to hold on to it.
I used a finger to start tracing the hard muscles of my boyfriends chest. "Mmm.. I don't know. What do you think, Daddy?"
He chuckled and shook his head. "Damn, I'll never get used to this shit. Did he really beg you for this?"
"Oh, absolutely," I replied. "He kept whining and begging to call me Mommy. It was all so sad so I decided to play along with the little tyke." It was true, at least partially. He had wanted to try some more femdom play in the bedroom, and I saw a chance to work in some of my... interests. It was a win-win, really. Plus, its not like it's my fault his little dicky never gets harder than when I'm taping him into a fresh diaper.
My husband started to protest. "But that's no-"
"Shush!" I said fiercely, giving his toddler harness a warning tug. "The adults are talking."
Daddy chuckled at my husband's meek compliance and grabbed my ass. "Ok, fine. You got me interested. Go ahead and let him do whatever fucked up thing you thought up." He laughed again.
I grinned sweetly and planted a kiss on his cheek. "Thank you, sir."
I stepped forward and bent down. "Come on, honeybunny. Show-time. Can you be a big boy and scoot around to face Mommy? Can you do dat? Hmm?" I patted my legs for effect, the way you do to get the attention of a distracted toddler.
His diapers crinkled loudly as he turned around and sat back, studiously avoiding any eye contact with the superior man in the room.
"Good boy!" I cooed approvingly, leaning forward just a bit more and patting his head.
His eyes were locked on my cleavage and I knew his little nubby would be hard and compressed as a diamond in his inch-long baby cage.
"Okay, sweetie. Just like we practiced. On three."
He nodded and looked away. "Yes, Mommy..."
"If you're a cucky and you know it, clap your hands."
"If you're a cucky and you know it, clap your hands."
"If you're a cucky and you know it, with a tiny dick to show it, then you're a cucky and you know it, not a man."
Except for my husband's quiet sniffles of shame, the room was quiet until my boyfriend let out a bark of laughter and pulled me back into his arms.
"Ok, you got me. I guess I'm a little fucked up too cause for some reason that turned me on."
I leaned in to put my lips against his ear while reaching down to grab at his thick cock through his jeans. "Mmm, good."
We started kissing and pawing at each other, movements getting more and more frantic until a plaintive whine cut through the haze.
I rolled my eyes and gently pushed my lover away. "You head upstairs, I need to take care of the little-guy real quick."
He snorted in annoyance and glared at my husband, who in turn cringed and began to suck on his thumb. Daddy looked back at me. "Fine, but unless you want a spanking you'd better hurry the fuck up."
As he stomped upstairs I reached for my phone and pulled up the app I was looking for.
My husband's eyes went wide as saucers. "Mommy NO!" He cried.
Signals from my phone zipped through the air to connect with the two tiny receivers inside my husband's diaper. The first one set the head of his chastity cage buzzing, relentlessly stimulating the sensitive head of his baby dick. The other caused the hollow-inflatable plug filling his pansy-pussy to rapidly deflate.
The back of his diaper rapidly ballooned outwards with a day's worth of "smushies" even as he had a #3 accident in the front, his cucky clit dribbling its mess all over the interior of the diaper. He was wailing and crying as he lost control over seemingly every bodily function and I stopped the vibrator to shove a fat paci-bulb between his lips and lock it tight around his head.
He looked at me, teary eyed and weak.
I smiled and cupped his cheek in one hand. "Mommy needs to go play wrestle with Daddy now. You be a good boy and make squishies while I'm gone. I'll change you when he's done with me, kay?"
I switched the glans-vibrator back on before he could respond and rushed upstairs. Taking care of such a big baby is hard work after all. I deserved a little reward.
