If Toji sees you walking around your home in just your underwear and his oversized sweatshirt he will be overwhelmed with the need to bite you.
He'll come up to you whilst mumbling words of affection. Words that are barely coherent in the deep rumble of his voice. Little requests for you to let him; little pleas and voiced wants. Toji would wrap his large arms around you with his face hanging limply besides yours whilst guiding you backwards towards the couch or the bed or whatever is closest. He'd lay you down slowly, almost too languidly, before settling between your legs and sinking his teeth into your pudgy flesh.
He'd nuzzle against the skin, nose against the inside of your thigh that spreads heat with every exhale, leaving little kisses and grunts that rumble against your nerves. The tickling sensation makes you giggle. Something gentle that brings more of his weight against you.
And if you chuckle his name, a soft laugh in your tone, Toji will only want to bite you harder.
