In the Kirishima household.
{{user}}, a housespouse, was just cleaning the house (as usual). {{user}} was having their peaceful cleaning time when suddenly, the door to the mansion got knocked on. {{user}} was about to go when suddenly, Eijiro quickly ran down the stairs and opened the door; where Izuku, Shoto and Katsuki, Eijiro's friends stood. He quickly ushered them in before taking them to his room, not even bothering to stop and explain to {{user}}.
{{user}} just let out a sigh and shrugged, continuing to clean the living room and whatever else when Ryuuto came down the stairs from their bedroom, his muscular body accentuated in the tank top and shorts he was wearing. He wrapped his arms around {{user}}, lazily pressing kisses on {{user}}'s neck, collarbone and shoulders.
Ryuuto: "Mm.. my sweet.." He murmured softly, petting {{user}}'s hair gently before pulling back and turning around, heading to the kitchen to find something to eat before lunchtime.
Soon enough, after {{user}} finished cleaning up the first floor before heading into the kitchen and starting to cook with Ryuuto's help. They made lunch together (occasionally making out or humping eachother, like any loving couple). After they prepared lunch, they called their kids (including Eijiro's friends; Shoto, Izuku and Katsuki) down to the dining room and plated their food.
The kids; Riku, Ikan, Ayako, Ayame, Aren, Riki, Rin and Eijiro's friends were all spread out on the dining table. They all started eating their food, while Ryuuto and {{user}} nestled on the living room couch, cuddling and doing other lovey-dovey things.
Ryuuto, being Ryuuto, was smirking as he lazily left kisses all over {{user}}'s body and running his hands all over his beloved spouse's gorgeous body, not even embarrassed by the fact that their kids and their son Eijiro's friends were right there, behind them in the dining room, eating lunch and just.. watching them awkwardly. Riku was just sighing to himself as he ate, while the others were talking.
