Jason liked being babied by Sufjan. He liked it so much, in fact, that he wanted his boyfriend to experience the same thing. With a grin, he edited a sentence and submitted it.
"I can't wait until we get back to the frat," Sufjan said. "I need a snack."
"I've got plenty for you, babe," Jason said flirtily. He looked down at his chest with glee. His pecs were now enormous, to the point that they could be mistaken for breasts. But he knew it was all muscle. All muscle and milk.
Thanks to his change, subs now produced milk. It took a while for a sub's milk to come in; the dom had to nurse from their sub multiple times a day to trigger milk production. But once it started, doms eagerly nursed from their partner, getting a benefit just like subs got a benefit in the form of diaper changes.
Male subs had to exercise their pecs constantly to keep them as muscle. Without the exercise regime, they would turn into man boobs. Female subs, who already had breasts, didn't have to worry about that aspect of nursing.
At the moment, Jason was the only sub in the frat; all the others were doms. Most were straight, though there was one brother who had a sub boyfriend elsewhere.
They arrived at the frat. Sufjan parked his car and the two boyfriends got out. They walked up to the front door, Sufjan squeezing Jason's wet diaper the entire time. When they entered, they made a beeline for the TV room. Most of the brothers would be there, and they liked showing off their relationship.
Jason sat in the enormous nursing armchair, his diaper squishing under him. Sufjan laid across his lap. Jason pulled up his shirt, exposing his nipples, already producing milk. Sufjan latched on eagerly. As he suckled, Jason could see his boyfriend's pants tenting, as his dick was hardening. Jason grinned. He knew what to do to make Sufjan fully come.
Jason pushed as hard as he could. With a loud fart, poop filled the back of his diaper. Sufjan grunted. Wetness appeared at his crotch. Jason's grin widened. He loved teasing his boyfriend like this.
Sufjan finished with one pec and moved to the next. While he drank, Jason pulled out the phone and generated a new sentence.
"Jason is the only diapered, lactating sub in the fraternity."
