Mukai Ai's "Gokkun" debut work!! Ai, a married woman whose husband is away on a business trip, works part-time in inventory management at a company full of men.

Ai tells herself that she can just endure it for a little while, and gives up on resisting. However, when Sanada's cock fills her mouth, she is overcome with a numbing sensation throughout her body...
