"Mmmmmnn... I'll reward you for being a good boy."

Yujiro worked part time at the convenience store, yet was recruited by a voluptuous 31-year-old named Reika to help out her luxury salon Chat Noir.
What started as a routine promotional job spritzing fragrances turned
into something very different though. The tension for Yujiro was building to a climax... and then he caught Reika masturbating.
