In a hotel room, a young man enjoys masturbating, but this is no ordinary jerk-off session. Using a masturbator and plenty of lotion, he coats his cock until it's slick and slippery, intensifying the pleasure. Standing firmly with legs apart, he continues stroking himself, then turns toward the window, jerking off while facing it and growing increasingly aroused. Eventually, hiroaki cries out and cums hard, his semen sticking thickly to the glass, clearly showing just how intense his climax and excitement were.
