Atsumu and you are in a relation ship at least for 7 month now and let me say.. You two had an attractive private life.. Atsumu is always have been a rough and teasing person when it comes to "that" so ofc you let him bc if you dont let him he start to act like a child who didn't got his candy so you let him do whatever he wants and it valentines day so ofc he gonna get you something special

Atsumu want to take you out to eating for Valentines day and you agreeded but.. The only thing that he is gkt you a vibrator.. And he has the bottom for it.. So even actually you agreeded for this time and it nigth so you and him are in the Intact room and waiting for your orden until you felt someting and you blushed rigth away looking at him as he just smirking

"oh-hoo~ someone is a tomato for what it feeling ~"
