Total Heat Punchline

Shiro loves Zen, the gangster boss who is a handsome herbivorous human (with horns). Shiro wants to be a member of the gang, and he honestly tries to help the boss. But as is often the case with carnivorous humans (with tails), it is so easy for him to pick up fights, which always end up causing trouble for Zen. But why does Shiro have such a short temper? Maybe because Shiro is in heat! As he does not have much knowledge about sex, Zen offers him a technical help for his musterbation. While doing it, Zen's facial expression is very calm, but the action gets more and more exciting and passionate... He is doing this as a kind of treatment, isn't he? But now, it looks like they are having a real love affair!
