She goes for a drink with a younger student who works part-time at the same place after work, and ends up letting loose... into an adult relationship. Moisture comes to her parched daily life, and she falls deep into an affair of escapism... "It's okay if it's raw, it's a day when I'm okay." No condom. They have raw sex like crazy. An age-gap affair couple revels in sex. Consensual sex between a beautiful part-time worker at a gyudon restaurant and a hungry student part-timer. The two of them are intoxicated by a fleeting affair during and after work.
