"I'm sorry" (Pet regression Oikawa IwaOi FanFic)

Part 4

The Next Day

Iwaizumi slowly wakes up and looks around his room to find his regressed boyfriend sleeping on his chest. He smiles then looks at the clock realizing it's pretty late. Iwaizumi gets up and sets Oikawa on his hip. Oikawa slowly wakes up and lets out a whine "I know you're tired puppy but you have to change"

Iwaizumi changes Oikawa then he walks into the kitchen with the smaller boy on his hip. "You hungry?" Oikawa just whines and lays his head on Iwaizumi's shoulder. "You tired?" Oikawa closes his eyes and slowly falls back asleep. Iwaizumi gets a small snack and sits on the couch while his regressed boyfriend sleeps.

An Hour Later

Iwaizumi hears the doorbell ring. He gets up and opens the door to see Tsukishima carrying a regressed Kageyama on his hip. Kageyama looks at Tsukishima "Wanna see puppy" Tsukishima points to Oikawa "look he's right there, he's sleeping right now" Kageyama pouts "but wanna meet puppy wight now" Tsukishima walks into the house and Iwaizumi closes the door.

"Thanks for coming over" Tsukishima sits on the couch "It's fine, Tobio really wanted to meet him so" Iwaizumi sits on the other side "If you don't mind me asking, how old is he when he is regressed" Tsukishima looks down at Tobio "How old are you right now, bub" Kageyama sticks up four fingers with a smile "Fouw!" Iwaizumi smiles "Wow bud, your such a big boy" Kageyama smiles brightly "Yeah!"

Oikawa slowly wakes up and lifts his head off Iwaizumi's shoulder. Iwaizumi sits Oikawa next to himself. Oikawa looks around but when he realizes there are people he doesn't know he gets a little shy. Tōru pushes his body in between Iwaizumi's back and the couch. Kageyama looks at Iwaizumi "Was he doing" Iwaizumi pets Oikawa's head "He's just a little shy"

Iwaizumi picks Oikawa up and sets him on the ground "Go on puppy, say hi" Oikawa slowly crawls over to Tobio and sniffs his hair. Kageyama giggles and looks at Oikawa "Doggie, that tickles" Tōru tilts his head then rubs his nose against Tobio's. Iwaizumi laughs nervously "Sorry about that I think his mom and I accidentally taught him that" Tsukishima smiles slightly "It's fine"

Kageyama stands up and since he is a little bit taller than Tōru he picks the shorter regressor up. Oikawa yelps in surprise and clings onto Tobio. Kageyama looks at Tsukishima "Why he make that soun" Tsukishima pats Kageyama's head "I think you just scared him" Kageyama sets Oikawa on the couch and pats his head "I sorry doggie" Oikawa stares at Tobio's hand then opens his mouth about to bite the littles fingers "Ru, no biting" Oikawa lets out a whine and stops.

Iwaizumi gives Oikawa a pacifier, Oikawa suckles on the baby soother and leans closer to Tsukisima then tilts his head. Oikawa brushes his head under Tsukishima's chin, then he sits himself in Tsukishima's lap. "Well hello there" Tsukishima pets Tōru's head. Kageyama looks at Iwaizumi "Puppy has paci" Iwaizumi nods "Yeah, it keeps him from teething" Kageyama tilts his head then he climbs up onto the couch and sits next to Iwaizumi "was teesing" Iwaizumi smiles "It's when he likes to chew on things cause he is a puppy" "Oh well I's chews on sings when I weally smaw" Iwaizumi nods "Do you have a pacifier" Tobio nods

Oikawa looks around then sticks his tongue out, making his pacifier fall on the floor. Tsukishima looks at Iwaizumi "uh is he okay?" Iwaizumi nods "He just does that when he is hungry" "oh" Iwaizumi looks at Kageyama "You wanna help me get Ru Ru a snack" Tobio nods happily "Cans I haves one too" Iwaizumi nods then stands up, picking Tobio up, and walks over to the pantry. The two soon come back with some baby snacks. Iwaizumi hands one to Tsukishima, then sits on the couch with Kageyama and gives him a snack. Tsukishima feeds Tōru the baby snack.
