Greedy boyfriend he had here. Ryuutaro felt himself blush a little, one hand tightening it's hold of Hayato's shirt while the other let go, traveling up to the back of Hayato's neck, drawing circles there.

For a moment he has to break away from the kiss to breathe properly (and take the chance to look at Hayato for a little moment), but then he already leans in again to continue it.
