Avengers Age Play One Shots [Requests]

July 22, 1939

"Morning, Stevie," Bucky smiled, gently shaking his baby awake. 

"Daddy," Steve hummed, sleepily. He rolled over in bed and rubbed his eyes. 

Bucky grabbed a diaper and wipes and started changing his baby. "Did you sleep good, baby?" Steve nodded, still barely awake. "Good. Ready for breakfast?" Steve nodded again, yawning as he was lifted into Daddy's arms. Daddy carried him out to the kitchen and placed him on the counter, grabbing duct tape. The store didn't have any diapers in his size, so Bucky had to get ones a bit too big; he uses duct tape to keep the diaper on him. 

"Outside?" Steve asked when he was placed in his chair in front of a plate of pancakes and eggs. 

The warm weather makes Steve's bones and chest feel good. He loves summer because it's always warm out and he feels good all the time! 

"Sure, babe. Eat your breakfast first." 

Steve nodded and dug into his pancakes and eggs.

After breakfast, Bucky got Steve cleaned and dressed and took him to the park. 

Three hours later, Steve ended up in just a diaper after someone dumped mud on his clothes. Bucky forgot to pack clean clothes, so it's a good thing Steve doesn't mind being naked. 

"Baby, come get changed," Bucky called when he noticed Steve's diaper sagging. Steve stood up from where he was playing with some bugs and he waddled over to his Daddy. Bucky lifted the baby onto his hip, carrying him and the diaper bag behind a tree for privacy. Bucky laid a blanket out on the ground before setting Steve down on his back on the blanket. 

Bucky quickly changed his baby's diaper and let him up. He didn't bring duct tape either, so Steve's diaper was falling down a bit. 

"Daddy come play buggies wif me?" Steve asked. 

"Sure, baby. Can you go throw this out for me while I put your blanket back in the diaper bag?" Bucky handed the dirty diaper to Steve who nodded and ran off in search of a garbage can. 

The two met back at a spot where there were tons of bugs crawling around, due to somebody leaving half their picnic there nearly two hours ago. It's probably safe to say they're not coming back now. 

"Ladybug!" Steve exclaimed, pointing at a ladybug crawling over his foot. 

"I see, baby. Don't hurt it." Steve gently nudged the ladybug onto one finger and let it crawl onto the ground. "What's that, Stevie?" Bucky pointed at an ant. 

"Ant." Steve pointed at another bug and named it. "Rollie pollie. Caterpillar. Spider." Steve cupped his hands and picked up the spider. He giggled, showing his spider to Daddy. Then, the spider moved one of its long legs and Steve screeched, throwing it into the air. The black demon with spindly legs came back down and slipped into the front of Steve's diaper, making him scream and start moving his arms wildly. 

"Shh, shh, it's okay, baby," Bucky comforted. "Calm down. It's okay." Bucky's so mad at himself now for not bringing the duct tape, but he ignored how mad at himself he is to undo the tabs of Steve's diaper, covering his bits as he allowed the spider to crawl out. Once it was gone, Bucky fixed the diaper and lifted the crying baby into his arms, rocking him until he fell asleep. 

"No more spiders for you," he whispered as he started walking home with his baby.
