Tired from a week of work, this married Japanese salaryman retreats to his private space, armed with a vibrator and an assortment of condoms. He teases his erect cock through the latex, simulating oral pleasure, before donning a new condom and turning up the vibrator's intensity. His body tenses, and his hips buck as he nears climax, ultimately erupting in a satisfying release, filling the condom with a week's worth of pent-up semen.
