Late-Night Sheet Washing - Mammon x GN!MC
Mammon is sound asleep, his arms around MC from behind until he feels something wet on his skin and soaking into his boxer shorts. He wakes up and despite his tiredness immediately knows what happened. "Oi, MC!" He shakes their shoulder to wake them up. "You pissed the bed again!"
MC wakes up and is horribly embarrassed, of course, but this is a nightly occurrence for them now. "I-I'm sorry, Mammon..." They mumble, getting out of bed and blushing deeply as they see the wet sheets.
"Ya know how much I hate agreein' with Lucifer, right?" Mammon frowns, starting to strip the linens from the bed to wash them. "But he's right this time. Ya need to sleep in diapers."
MC blushes harder and shakes their head, starting to help with the sheets. "I-I do not!" They insist, but it's hard to insist you don't need diapers when you've soaked your boyfriend's bed for the third time this week.
"Ya do, and ya know ya do, too," Mammon frowns. "I don't wanna do this to ya, treasure, but... yer not sleepin' in my bed anymore unless yer in a diaper."
"You can't do that, Mammon!" MC protests in their wet pjs. "You know how much I enjoy sleeping in your bed..." They try to give him their best puppy eyes, but he turns away.
As much as it kills Mammon to do it, he turns MC away when they want to sleep in his bed the next night, since they're not diapered and he's not getting up at 2am to wash the sheets again. They're upset, but head back to their own room.
Mammon wakes up in the middle of the night anyway, needing a drink. He leaves his room and passes MC in the laundry room on his way to the kitchen. "MC..?" He pokes his head in and sighs, seeing that they are washing their sheets.
He decides that this is enough; if MC won't help themselves, he'll have to help them. "C'mere, treasure," He picks them up and carries them back to their room, laying them on the dry part of their bed and pulling out the pack of diapers Lucifer had insisted they start wearing at night, which they hadn't even opened.
He rips open the pack and unfolds the diaper, grabbing MC's ankles and lifting their hips, sliding the diaper under them. They try to squirm away, but he gently holds them down as he finishes diapering them, holding their hands after so they don't immediately try ripping it off. "Treasure, this is for yer own good, yeah? Ya need to listen to us sometimes."
MC tries to move away to take the stupid thing off, but a gentle tickle from their boyfriend makes them squirm and start to giggle. After a couple seconds of tickling, they gasp as they feel themselves starting to pee again, just enough to leave their diaper damp and warm.
"See?" Mammon asks, pressing the wet padding against them to make sure they feel how wet and warm it is. "Ya just proved ya need 'em."
MC blushes furiously, but they can't really deny it anymore. "F-Fine..." They grumble.
They get to sleep in Mammon's bed again, so long as they let him diaper them first. While they're still embarrassed about it... they do have to admit that they'd grown tired of late-night sheet washing.
