Minato Mochizuki, a Sub who has broken up with his partner, is becoming increasingly frustrated. That's when his friend Yoh advises him to use sex services. Although anxious, he waits for his escort at a hotel. The one who shows up is the most popular escort, Seiya, a handsome man with a well-proportioned face. Seiya's gentle character makes Minato comfortable enough to start their role-play, and his soft touches and the commands he whispers are simply too sweet... but something makes him change completely!! "You actually prefer your partner to be strict, don't you?" Ordered to expose his innermost self, a sweet pain and an unknown pleasure mix up, making Minato crave punishment instead!
