J-series: A stepdaughter with a large ass, whose wife is overly cold and unapproachable, is trained with a remote-controlled vibrator to induce urination, developing a vagina that loves her father's spasmodic orgasms, and receiving ample rewards for ejaculation inside her. (Jun Tsukihiro LULU-432)

My wife and stepdaughter are difficult to approach. Even when I try to talk to them, they're cold. This won't do! I must demonstrate my fatherly authority…! To make my stepdaughter obedient, I use a remote-controlled vibrator for clitoral stimulation! Multiple clitoral stimulations bring her to the peak of sensitivity, causing her to squirt and climax! As she gradually becomes more obedient, I insert my penis as a final blow, rewarding her with ejaculation inside! Repeated urination and climaxes, my stepdaughter, addicted to the remote-controlled vibrator, grows into a girl who adores her father.
