Ryuutaro bit his lip, but he couldn't hold back a frustrated moan. This was a so mean, he wasn't in control at all anymore and he needed Hayato just so badly now. Some more gasps escaped him as the teasing went on and on... it was so hard to take.
"Q-quit this...", he breathed out, "I..."
He what? Ryuutaro didn't quite know how to continue this and instead just pushed back against Hayato a bit more, his self-control and pride vanishing.

"Just... do something..."

There, Hayato. Fix it, now.
