Description from english DLsite:

A hospitalized guy was hornier and hornier as he lay in the bed, receiving care from cute nurses.

"If your c*ck is too full, we can help you with that," said two of them.

That was the first day of a new hospital life, where every day was a refreshing purge of sperm.

Yeah, I know it's a rough translation but it should make it easier for people to find it if it matches the one on DLsite.
