How to Train Your Puppy

Sasaki works for an adult toy company. Souta Nakamura, a puppy-like jock (who's also an idiot) gets transferred to his department. Souta's very motivated and begs Sasaki to test his sample product. Sasaki agrees, but he feels awkward using a fleshlight while being watched... But things start to go even further and they eventually...! An office love story between the "jock puppy" Souta and the socially awkward Sasaki, who himself is in an odd relationship!
