Morty started to squirm, “M-my tummy… it’s hurting…” he whined.

Rick knew very well what was happening but managed to hide his smirk very well. "Hold grandpas hands, bubba." Rick said in a soothing tone. He held Mortys hands firmly but gently as he guided him into a squatting position. "Alright, just breathe and relax, bubba. Deep breaths for grandpa, take your mind off it. Grandpas right here and I've got you." Rick said soothingly.

Morty blushed and slowly started to squat, “G-grandpa… w-what are you mfff… d-doing?” Morty asked, the pressure in his tummy building up more and more by the second.

Rick slipped a paci into Mortys mouth and held his hands. "Shhhh don't worry about that, baby boy." He said. "Just listen to grandpa. Suck your paci, hold his hands, take slow deep breaths and relax." He added. "You can do it, bubba." He said.

Morty’s gave turned red as he tried to follow the advice, he took deep breathes but his mind wouldn’t let him go, he was still too nervous and quite embarrassed about the whole ordeal.

Rick gently kissed Mortys head as he kept trying to help you relax. "Hmm... Alright bubba Grandpa's gonna lay you down." Rick said, laying Morty down. "Here, hold your guardian baby boy." Rick said, handing Morty a stuffed animal of a fluffy dog. Rick then placed both his hands on Mortys tummy and slowly but firmly began to push onto his belly. "Don't fight back Morty, just relax and let it happen. Grandpa knows what's best for you." He said.

Morty started to blush and squirm, “W-wait! Grandpa n-“ Morty stopped mid sentence as he started to grunt, unloading a hefty load into his pampers!

As soon as Rick saw Morty filling his diaper he smiled and kept pushing on his belly. "Good Boy Morty! Grandpa is so proud of you!" He braised. He kept pushing until Morty finished messing himself and stopped pushing on his belly. "Don't worry bubba, you'll get better and better at filling your Huggies over time." Rick said. He helped Morty stand and smothered his face in kisses to show him how proud he was.

Morty blushed as he felt the mess expand his diaper out, pressing against his onesie and making it tighter, “F-filling then more?” Morty asked with bright crimson cheeks filled with embarrassment.

"Well yeah, silly baby, you are in diapers 24/7. Babies wear diapers and use them. Grandpa is so proud of you." Rick said, smiling. He picked Morty up and gently bounced him in his arms, keeping a hand under his messy crinkly butt firmly.
