An Old Bottom wants to be loved -Obsessive sex with a younger doggy

This review contains spoilers. I had a feeling it was Ao-kun that got rejected at the start, but as fate would have it, their paths crossed again & they finally got together, although not without a few bumps in the road & Ao-kun getting jealous because Sakai kept hooking up with other men! Hahaha And that was a slap to Sakai's former teacher lover's face when he saw that Sakai was happily committed in a relationship while he was stuck in what probably is a loveless marriage. The role playing they did in the last chapter made them both get so immersed in their roles that eventually got Sakai hooked on doing more lol
