[Sentaro]

Rin kept on pleasuring himself while his brother was away. It felt really nice though it was hard to stop once he started. The demon boy stroked fast and faster while taking care of the back as well. He didn't even heard that his brother came home and walked towards their room.

Rin bit his lip softly as he came all over his hand while gasping out Yukio's name. Panting softly he fell flat on his bed. Just at that moment Rin opened his eyes, he hadn't noticed he closed them, to see his brother already back. "W-what!? Y-yukio you're already bacK?" He asked his voice shaking softly as his whole face turned red.
