The new semester started and both of the young ladies were busy with schoolwork. Things were hectic, but stability soon returned as they worked out their routines. Mei-Lin even solved a persistent computer problem for April that was causing frequent crashes.

All was going well for the roommates when things settled down into the standard daily march to the end of the semester. Mei-Lin diapered April every evening as soon as she got home. That was until April came home late one evening with the stench of cheap beer on her.

Mei-Lin turned sternly to her roommate, "You've been drinking! You smell like a brewery!"

April smiled, "There's this cute assistant professor. He is my degree advisor. He also lectures my seminar class. Several of us went to the pub to start a study group and the assistant professor dropped by for a beer with us."

Mei-Lin didn't miss a beat in her response, "Well, you didn't call or text. I worried about you."

"I'm sorry," slipped out of April's mouth.

Mei-Lin shook her head, "Well, it better not happen again. Come, it is time for your diaper."

April followed the smaller woman to her room like an obedient puppy. There she removed her clothes. Mei-Lin pulled a diaper from the bag that was no longer hidden under the bed.

"I'm sorry I missed supper," said April.

"Yes, you will be more sorry," said Mei-Lin as she pulled the larger girl over her lap on the bed.

Mei-Lin spanked April's bare bottom hard with her bare hand. April cried after the first smack. Mei-Lin gave her five firm swats before she stopped. Mei-Lin tugged at April's shoulder and she sat on the bed next to Mei-Lin. The opportunity she had hoped for emerged when April put her head on Mei-Lin’s shoulder.

"I deserved that," sniffed April, "I know I did. I'm so sorry to have let you down."

Mei-Lin kissed her roommate on the lips, "It's OK. You forget. You need someone to look after you, to take care of you. That's who I am."

The girls fell back onto the bed. It was Mei-Lin's first serious romantic encounter and April's first time with another woman. They were gentle with one another and explored each other. Mei-Lin stopped short of either of them climaxing and diapered April for the night. Mei-Lin slept with April that night in her bed. They cuddled that night and fell asleep in each other's arms.

April awoke to Mei-Lin's hand in her crotch and a question, "Even with all that beer, how are you dry this morning?"

The blonde blushed and tried to cover her lie, "I, uh, I don't wet every night."

What April didn't know was that Mei-Lin had checked her trash every day and every diaper was wet that she found. April was lying to her.

"No, that is not it," said the smaller, black-haired girl as she rubbed April's crotch through the diaper, "I think you LIKE to wear diapers."

April couldn't utter a word as she was quickly building to an orgasm from Mei-Lin's hand and her diaper desires. April kissed her as she exploded into her diaper. With Mei-Lin's hand still on the other girl's crotch, she felt a sudden warmth spread beneath the material.

"April, did you wet?" asked Mei-Lin.

April didn't speak, but moved her head up and down with a grin. Mei-Lin kissed her again and worked her to another blissful orgasm before Mei-Lin opened the girl's diaper and sent her to the bathroom for a shower.

While April was in the shower, Mei-Lin composed herself. She used her laptop with an anonymizing proxy to conduct some hasty research into diaper fetishes. She wanted to find out more about what made her kinky roommate tick.

If she were to make dominating her naughty blonde roommate a worthwhile hobby, she needed to know what buttons she should be pushing. She quickly bookmarked a few sites for later reference and took her turn in the shower. Mei-Lin relieved her pent up sexual desire with the shower wand on the pulsation setting while fantasizing about April.
