Really Regressing

Aberdeen was on her stomach, watching some toddler show, obviously deep in a babyish headspace. Abbelina was at the kitchen table, coloring her "F is for Fuck!" Adult coloring book. Abebi just got to business, getting food put away.

Abe went to stow the diaper cases under the changing table, Abigail knowing she needed to be in arm's length stuck to him like a shadow.

"Okay, you are adult-y, I really really want to fuck, can you get us both clean? And I want all your toys in the bed with us." Explained Abe as he got on the changing table. Abigail started wiping, "So we gonna do a wotta humpy humps?" The blonde asked around her pacifier.

Abe nodded, "Yeah, gonna have diapees outta da way and put my pee pee into your pee pee. And we gonna have our wattles and teethers." He said, joining her in infantalizing even when the subject was so adult.

Abigail could only suck hard on her pacifier in want as she started wiping Abe's bottom. As soon as he was clean he ran bottomless to the bedroom, to get the bed liner out. He was quick to find Abigail's box of toys to dump out across the bed. It didn't take long for the blonde to come to the bedroom, carrying two diapers with her. She adored diapers and if she wasn't wearing one, it would be good to have at least one on hand to touch and grope.

Soon Abe was on top of her and in her. They started out quiet as church mice, the two very pacifier dependent. But as Abe had promised, they were shaking baby rattles as he railed her. Cumming once, Abe became twenty two. Surging with energy, he flipped Abigail over, planting her face in the pillows and holding her ass up in the air. He held on tight and just kept rutting. Adorable squeaks were slipping past Abigail's pacifier. He came, becoming twenty one. Feeling the second orgasm building upon the last one, he spat his pacifier out and started to growl, catching even himself off guard as he kept slamming his meat into the blonde adult baby.

The building pleasure of orgasm followed by orgasm, being able to have them sequentially, he was building up to a hair trigger. He came, and came, and came, 20, 19, 18, his eyes were practically rolled back, the bedliner was being splattered with fluids as he kept displacing the previous load and having hit Abigail's internal capacity. Abigail had taken 5 loads into her womb, surpassing Aberdeen's count and becoming the most likely to unbirth Abe if he managed to fuck his way out of a positive age. Cumming again, his skin started to feel a bit oily, as he became 17, he wasn't especially fit but he was losing tone and mass, adjusting how he was hitting Abigail from behind.

"Flip back, baby flip, huggy kissy again, gimmie boobies..." Abe grunted, voice starting to have random cracks/squeaks. Abigail complied, but put one of the diapers she brought down to be on, holding her knees back, looking ready for a diaper change. Abe thrusted in, being sure to get a tit in his mouth to suck on. He came, swapped breasts, came, nuzzled his face in the cleavage, cumming again. The breasts seemed to be getting bigger, but he was 14 now and becoming shorter, even if he wanted to kiss Abigail, he couldn't without pulling out. He was on his way to being a diapered shouta with a harem of big mommy girlfriends. "Fuck yes, fuck yes" he called out, voice noticably higher, he was becoming a diaper using preteen and even if he wanted to hold back, he couldn't. He came and turned biologically 13.

Abigail was in awe, seeing the years melt off of Abe Dell, his cock was getting smaller but he was still cumming. She understood that he was mentally an adult, fully able of consenting, but the radical change was offsetting the pleasure she was having. She easily sat up, forcing him to pull out, and shoved him on his back, taking the small cock in her mouth. Even if she had a gag reflex, she doubted it would have been triggered. She swallowed the next load, and Abe suddenly collapsed. He was exhausted after the marathon session. He was doing all he could to catch his breath.

Abigail taped her diaper up, the excess cum filling the front. She couldn't wait to just rub her diaper. But for now, she needed to diaper Abe. The diaper that would have fit him now swallowed him up, going beyond his navel, the wings overlapped, she did her best to get him secured. Once her heart rate was even, she trusted her footing, picking up Abe as if he was a baby at his more manageable size, to carry him out and show him off to her harem sisters.
