Do S Kareshi wa Amakute Hageshii
Tsukasa works as a male-targetted prostitute and strictly sticks to an ultra-efficient policy of earning money with only oral service, with no full intercourse involved. One day, he mistakenly makes a move on a porn video staff member, Yugo, thinking he’s a client. Trying to make Yugo climax with his usual skill, he’s told that he sucks at it. Before he knows it, Yugo takes charge in an unexpectedly dominant lecture—and Tsukasa ends up climaxing first...!?
