Kate could barely think straight as she massaged her dick through her panties. Men’s underwear was out of stock everywhere since the swap, but it was a non-issue for the moment, since Kate’s dick wasn’t big enough to cause that much discomfort yet (a fact that made her feel deep shame). The only time it became a problem was when she got a boner, and then her hot little rod rubbed against the lace in such a way that made her heart race. She was glad Dave was out of the house for the afternoon, so she could fondle herself without him knowing. She knew how emasculated and intimidated he was that she and Mia had cocks and he didn’t.
She had been passing by the window when she saw the neighbor boy Sammy awkwardly going out to his family’s backyard pool. The teenage boy had perky, firm breasts, and Kate couldn’t help noticing the boy’s new way of walking to accommodate his new parts. He was clearly wearing his petite mom’s bikini, as the top was stretched to the limit, and the bottom was engulfed in his huge camel toe.
Kate fixated on his new feminine parts and a yearning deep inside her started to stir. Sexual attraction had blown up on a global scale, with everyone having different parts of different genders, ages and sizes, it had become hard to keep track of. The only thing keeping Kate at bay was the fact she couldn't cum yet, but she wanted it so, so badly. The constant morning wood and hard-ons at every part of the day without release was adding to a mounting need. All of her former adult arousal was contained in these new boy parts, and it was driving her crazy. She couldn’t even imagine what her husband was going through. He was probably equally horny, but now trapped with the pussy of their baby daughter…he wouldn’t be able to find relief for another decade or so.
Kate stared a moment longer out the window, just in time to see Sammy take a few steps and rippppppp. His top exploded, leaving his pert boobs jiggling out and free. Kate’s breath caught in her throat, and like instinct, she put her hands down her underwear and started to tug. Fuck, it felt so good that she didn’t care that she was peeping. She’d never even been attracted to boobs or vaginas, but now things had changed. She watched with newfound interest as Sammy tried and failed to cover himself, and his bosom was on full display. Kate felt the oncoming surge…like she once felt when she had her pussy, and it was going to erupt.
A baby’s wailing cut through the moment, and Kate blinked. Mia was supposed to be down for a nap in the other room. Kate felt a dull ache in her stomach and crotch. The sudden case of blue balls made her want to cry. She was so close to release - she could almost feel it! But Dave was still out, and she had her baby to take care of. She turned away from the window and went to see what Mia was fussing about.
Mia screamed and squirmed in her crib, and as Kate stepped into the room, the stench of musk hit her hard. The baby’s chest was covered in Dave’s hair, as well as her bushy crotch. That plus her thick cock and balls really overpowered her once innocent scent into a testosterone-laden mess. The doctor told them that the rest of her body would develop as if she wasn’t outfitted with a grown man’s genitals, but that made Kate more confused for Mia’s future. She would just grow up to be a girl without boobs, but with her father’s dick dangling between her legs?
“Shhhh, it’s okay, baby,” Kate sighed, trying to readjust her own parts in her pants. “Did you make a mess in your diaper?” The cloth diaper was misshapen and ill-fitting, since they couldn’t put it on her tight without restricting her penis. The fabric looked damp, and Kate carefully peeled the front away and gasped. Mia’s dick was dark pink, throbbing, and rivulets of precum were gushing down from her slit. When Kate let the front of the cloth diaper drop, it slapped to the bottom of the crib with a loud squishing sound. Mia hadn’t soiled herself in her sleep…she needed relief.
“Fuck,” Kate grumbled. Dave had been taking care of Mia’s “needs” while Kate was at work. Kate had cleaned up Mia plenty, but milking her? The prospect seemed insane. The baby continued to cry, and Kate stared down at Mia’s thick, glistening cock - the one that should be hanging from her crotch if she’d been faster getting home the day of the swap.
“Alright, c’mon little girl,” Kate shook her head. She scooped Mia in her arms, carefully avoiding the bouncing cock. There was a real weight to it as Kate brought Mia into the living room to sit comfortably on the couch. She sat Mia onto her lap, and it was then that Kate realized that, in this position, it looked like Mia’s cock…was hers.
Now that it was unencumbered by the cloth diaper, the shaft stood out another inch or so, and stood straight up before Kate’s eyes. Unlike the small, pale boy wiener she had tucked away, this was a real man’s cock, even if it was attached to a baby. She ran her fingers underneath its heft, and then let a copious amount of precum coat her fingers. Soon, she was running her hand along its entire length, slipping and sliding against the hot, spongey skin.
At first, she thought that it was like any time she’d given her husband a handjob, but as she got into it, she imagined that this was her cock. That this massive behemoth was something she would have to stuff into her pants at work, and that she would show off in the bathroom like her coworker Jen had done. She imagined Dave with breasts like the teenage boy next door, and what it would be like to dominate him with a big cock like this…maybe even getting him pregnant….
Kate’s small dick tensed at the fantasy, and Mia’s crying gave way to contented coos. Kate clenched her butt with each cascading wave of pleasure adding to the pile growing inside her, and she felt Mia’s penis pulse.
“Oh yeah, just a little more,” Kate soothed, and baby Mia gurgled in a daze. “Just a little more…a little more….” Kate was moaning now, feeling a new, warm sensation deep inside her. She jerked Mia faster until that mounting dam of pleasure broke. A dull pain flashed for a second before Kate knew what was happening. She felt the alien gushing sensation, and then it was her time to grunt.
Kate felt globs of hot liquid ooze out of her penis and she was frozen to do anything but feel how strange and uncomfortable it was. Her prepubescent dick was ejaculating for the first time, and she let out a guttural groan at the slow, pushing sensation. Soon, the front of her pants was soaked in hot, sticky fluid, and Kate’s mouth hung open. Her hand was still on Mia’s member, and Kate was too dazed to react to the feeling of the cock tensing in her grasp.
The baby’s cries became grunts, and then suddenly, jet after jet of viscous cum arched over Mia’s head and right into her mommy’s face, mouth, and flat chest. The amount of semen was a flood compared to the small puddle in Kate’s pants. She coughed, spitting the goo onto the cushions. Kate was frozen, feeling the warm globs of cum quickly cool, and she looked down at Mia, whose softening cock flopped down on top of her like a wet pool noodle.
Once she realized what had just happened, Kate looked around at the mess all around them, and the white streaks staining the couch. There was going to be some explaining to do once her husband came home.
