He couldn't believe it. The amount of pleasure he was getting from his chest alone was enough to make him dizzy. He weakly snaked his arms around Ryu's neck, surrendering his body to Ryu's onslaught, knowing Ryu would not stop until he's satisfied. His balls churned and he knew he was close.
"R-Ryu..." he moaned, crossing his legs. "I-I-" but before he could complete his sentence, his orgasm hit.
He held Ryu tight and closed his eyes as a huge wave of pleasure washed over him. His toes curled and he let out a loud cry as cum gushed out his dick like a broken tap, splashing down his thighs and Ryu's leg then going down with the water current.
His body spasmed, as if he was being shocked by electricity, desperately gasping for breath.
Ryu held him the entire time, still sucking in his swollen chest as he came down from his high.
