While his wife is visiting her parents, the busty sisters who live next door and are working as nursery school teachers are put in charge of "taking care" of the useless husband!? With their massive breasts spilling out of their revealing loungewear one after another, the man's crotch reaches its limit! Noticing the man's arousal, the sisters transform from gentle caretakers into lusty sluts. "Hey, which do you like better, your wife's breasts or yours?" Sandwiched between the sisters' huge breasts, the man has no way to resist and his reason completely collapses! He thrusts violently, repeatedly ejaculating deep inside the sisters, but the two lusty sluts won't let him off the hook!?
