Midoriya ~ Most of the time you two just wrap each other in your arms. There is no big spoon or little spoon.
Bakugou ~ He's always the big spoon. He holds you very tight, being the protective boy he is. While you "draw" things on his arm with your finger.
Todoroki ~ He's always the big spoon too. You two are always constantly kissing.
Iida ~ It's a mix on who's the big or little spoon. You two love to hold hands too.
Kirishima ~ This manly boy wants to be the big spoon a lot. But his soft side gets to him and he let's you be the big spoon when you want to. He loves kissing your hands, stomach, arms, you name it.
Kaminari ~ Your the big spoon. He loves to tickle you, and you tickle back. >;)
Shinsou ~ He's always the big spoon or your laying on top of him. He's an overprotective boy too, so he keeps you close to him.
Dabi ~ He is always the big spoon. If you want to be the big spoon, he refuses. He loves to tease you and you both kiss constantly. You love putting your head in his neck.
