He can't help it- he can tell that Yu is enjoying this as much as he is, and it's that thought alone that really makes this all worth it. Besides getting an awesome handjob. That makes it well worth it too. He's not even sure why he was so freaked out by the idea of sharing himself with his boyfriend like this, but with all things, it would take time. But everyday made him feel more and more comfortable with this, with this idea, and even more with Yu. And he already felt a great deal of comfort with him.

Breaths sharp, he can't hold it in anymore. The building heat was too much to handle, spreading through him entirely, mind turning completely to mush. He even tries to get out a meager 'I'm sorry' to Yu, but that's cut off by the moan of complete pleasure he lets out when he feels himself release. His own hand on his partner slows, weakening with the release, but not quite letting go.

He can't stop now, he owes it to Yu...
