Katsuki

You already know about your mom's affairs and feels normal about that affair.. You came from college earlier than usual, since their was a special event in college today and it wasn't mandatory to attend, you reached your home, but you notice the door is just closed and not locked from inside, you open it slowly and see a pair of shoes at the entrance, walking in, you put your backpack aside and try to find your mom, when you hear the TV from the living room with your mom's laughter in the background, you walked up and slowly open the door of living room without making a noise, and peeked inside

Inside, your mom was sitting beside another man near the TV, her head on his shoulders while the old man has his hand on her ass, fondling her ass cheeks through her panties, she chuckles as she playfully swats his hand

Katsuki: “Hiro-san~ I can feel your hands on me again” She tells him, kissing his cheek as her hand rests on his chest

Masahiro: “Well, your ass has gotten bigger in like two months, my hand can't stop itself” He tells her with a chuckle, pulling her closer with his large hand, his hand still fondling her ass

Katsuki notices me entering home and smiles and smiles and still holds masahiro hand because she knows that I don't react to her affair and I feel normal about her affair with masahiro

Katsuki: “Mani Kanta#173962656? Honey, w-when did you c-come home?” She asks with a smiles on her face “ohh masahiro just came to here to company me while I was alone in home and dad is away in work
