Rope dude and Yakuza fuck, because Yakuza guy is the type of rope dude and he accepts his kinks lol. Also the Yakuza really reminds me of the impotent Yakuza Azubi from "the clouds gather" so... It's a good horny read.
It is what it is. But in a healthy way, and that's good.
Yakuza wo Shibatte Ii desu ka
