That night, Kurt had woken up to the familiar feeling of damp sheets beneath him and he fought back tears once more as he sat up.
He never expected Sebastian to come into his room, making him blush furiously as he tried to hide the wet spot with his comforter.
Sebastian said nothing, simply picked him up and set him in his lap, not caring if his pants got soiled.
Kurt whimpered in protest and tried to push out of the other boy's hold, but Sebastian held him tightly.
"Did you have another accident, sweetheart?" Sebastian asked coolly.
Kurt's face burned and he look away in shame.
Sebastian shushed him and rocked him gently, cradling his face in one hand.
"Let's get you cleaned up." He cooed. He picked up Kurt despite the boy's timid protests, carrying him to the bathroom. He started running water for a bath before making Kurt squeak when he quickly stripped the boy.
"Stop. I can do it myself." Kurt blushed, covering his manhood with his hands.
Sebastian didn't respond. Instead, he picked Kurt up and carefully set him in the tub.
"Sebastian!" Kurt squealed. "Stop it!"
"No." Sebastian said simply.
"I'm sorry?" Kurt asked.
"N-O, no." He replied.
"I'm not a baby!" Kurt snapped.
Sebastian walked over and kneeled next to the tub. He produced a washcloth and soaped it up before reaching to wash Kurt's arms.
The brunette slapped his hand away. "I'm not a little kid, Sebastian. You're being a douche. Let me up." He ordered.
"Nope." Sebastian said, gripping Kurt's hand firmly and gently scrubbing it.
"Why not?" Kurt demanded to know.
"Because I'm not the one who had an accident in bed." Sebastian replied.
Kurt's face turned red with new shame and he allowed himself to be washed.
Not wanting to overstep his boundaries, Sebastian left Kurt to wash his privates while he left to get the boy some clothes. When he returned, Kurt was out of the tub with a towel around his waist. "Here." Sebastian said, handing Kurt the fresh pajamas. While he dressed, Sebastian stripped the sheets off of the bed and put on new ones.
When Kurt came back in the room, Sebastian led him to the bed and sat him in his lap once more. Kurt wasn't exactly sure why, but seeing the freshly made bed pushed him over the edge and before he knew what was happening, Sebastian was cooing to him and rubbing his back as he cried into the taller boy's chest. He had eventually fallen asleep and Sebastian laid him down and tucked him in before going back to his own bed.
The next day, Kurt spent the morning and afternoon thinking about Blaine and Sebastian's offer to make him their baby. Yesterday it had sounded crazy and awful, but if it was anything like the way he was cared for last night, he wouldn't mind it.
The day after, Sebastian and Blaine were in the kitchen when Kurt came in and stood in front of them, staring at the floor. Sebastian drank some coffee to hide his smirk.
"Okay." Kurt said quietly.
"About what?" Blaine asked, thinking the baby idea was dead and gone.
"You can be m-my daddies." Kurt said, blushing furiously.
Sebastian smiled widely and nodded to Blaine, who was looking at Kurt in surprise.
"You know what it means, right? You'll have no freedom to do or go where you want anymore, we're in charge." Blaine said.
Kurt nodded.
"And we'll feed you and dress you and bathe you, and you'll wear diapers and everything." Blaine warned.
"I-I know. And I accept that." Kurt said almost inaudibly.

Sebastian grinned. That turned out to be the best choice Kurt ever made. For everyone. He heard Blaine calling him softly and closed the nursery door all the way before going downstairs.
