Haruyuki, the eager amateur, finds himself in the throes of self-pleasure, his hand eagerly stroking his rigid cock. The cramped space around him barely contains his lust, as he feverishly works his thick, vein-ridden shaft. The slick, pre-cum coated head slips effortlessly through his tight fist, the friction sending jolts of pleasure coursing through his body. His balls, heavy with desire, swing gently with each thrust, the anticipation of release building with each passing moment.
