After three years of marriage to my beloved wife Yuki, we find ourselves drifting apart due to her stressful job as a middle manager. Despite her efforts to encourage me, she has been spending more time masturbating at night than usual. One day, I invited our subordinate Satsuki back to our place after work. As they got increasingly tipsy, Satsuki suggested that all three of us sleep together in a riverbed position since there was no more public transportation available. Although nervous yet aroused by the prospect, we eventually fell asleep... but were awakened by strange slurping sounds coming from somewhere nearby. *Note: Content may vary depending on distribution method.
