Papa’s little Hero: Universe 1 (private rp)
 

Mario sighed happily as he got his diaper taped up and his cat onesie put on. He thankfully he had given himself the day off today since he had recently been invited to a go karting tournament for what seemed to be the thousandth time. And that gave him plenty of time to regress and play with his little toys or so he thought. Once he finished getting ready he got out his favorite cat plushy Mr. Skittles and went to take a nap on the couch after playing with said plushy for about a hour.

Bowser had been making plans on how to have fun with Mario when he had peeked into his window seeing the sleeping Mario. Huh maybe I can use this to make him far more happy. I just have to play this smart. He smiled and opened the door with the spare key

(I thought that they started dating before the events of the rp)
He was still sawing some logs as he slept unaware as to what was going on outside of the house or who was outside of it.

Bowser smiled and went over to check his diaper

The diaper was dry and Mario started to wake up when he felt someone press against his diaper and he blushed hard when he saw his boyfriend “when did you get here bow wow?” he asked using his pet name for the koopa (why can I see him being forced to undergo unpotty training?)

Well little one I just got here a minute ago and couldn’t help but think how adorable you look in that

He blushes hard “Could you please leave the room for a bit so I could get changed into my normal outfit?” he asked

Why I don’t mind babying you at all baby boy

“Are you sure?” I just don't want anyone else to find out considering you and I are the only people who know.

Well what if I take you back to the castle where I can pamper you in private
