Johnny and Kari -- two 20-something college kids.

Wabbit Warren Apartments is a five-story apartment complex with at least ten apartments per floor. It had full accommodations, including a community WiFi network, a pool, an artificial lawn and garden on the roof, and a daycare on the first floor for parents who needed to go out for work.

On the seventh floor, Apartment 7C, there lived four people -- two men, two women -- and they split the rent evenly. That said, their dynamic wasn't exactly just "four roommates" and more like a family dynamic.

Sleeping together in the same crib was a man and a woman. They were both in t-shirts -- him a pastel yellow, hers a shade of pink that brought birthday cake to mind -- and a pair of diapers. His was blue, hers was also pink, and they were extra-thick to prevent leaks as they slept through the night.

Kari was the first to wake, though not immediately. She cuddled up against Johnny's shirt like a teddy bear.

"Morning, baby boy," she muttered against his chest.

Johnny, just barely awake himself, rubbed his eyes before wrapping his arm around her.

"Morning, baby girl."

His loins felt euwey. He vaguely remembered that after Doug and Brenda put them both to bed, the two of them were quick to get intimate. This time, they didn't even attempt to undress. She had climbed on him and rubbed the fronts of their diapers. Doug and Brenda, or "Mommy and Daddy", had slathered their no-no areas with a large helping of baby oil before putting them in their nighttime diapers, so both of them were very well lubricated. The blanket was covering both of them, muffling the sound of their diapers rubbing against each other, and they tried to muffle their mouths with very passionate kissing. It didn't take long before both of them fell asleep in each other's arms after a quick orgasm.

Without even thinking, Johnny let go and felt his diaper go from cold and clammy from cum, to warm and inviting from pee. He didn't need to worry about the state of his diaper. That wasn't his job. Kari didn't need to pee, as she had wet herself before she even fell asleep.

Johnny and Kari had been dating since high school. The two of them became intimate, had their first time together, and even agreed to go to college together. One day, a bashful (and slightly drunk) Johnny admitted to an also tipsy Kari in the middle of tearing each other's clothes off that he had a fantasy where he was treated like a baby. Wouldn't you know it, she actually had the exact same fantasy.

The two of them would swap roles, one of them being the "baby" while the other took care of them, and they took to it fast. While looking for colleges, Kari had discovered a community college with a special ABDL program, and was surprised to discover that the Infantilist Colony people had been talking about online was real.

It was a dream come true. A surreal dream, but it had come true nonetheless.

Johnny and Kari both enrolled and were accepted almost immediately, and they were super excited that they were finally moving in together.

The college had its own "Campus Adoption Program", a publicly funded campaign that allowed students of the ABDL persuasion to find places to live during their time at their community, subsidizing rent costs for both the students and whoever was willing to bring them in. Doug and Brenda were the two who had agreed to take them both in, essentially "adopting" the two of them.

While not ABDLs themselves, Doug and Brenda were natural-born caregivers and agreed to the "adoption" program.

While the two of them would occasionally go out as "adults" when the mood suited them, Johnny and Kari and grown to playing the role of "baby" most hours of the day and night.
