On her first day, new caregiver Miina heads to a share house where men who need care gather. Miina, who is weak to pressure, gives in to the momentum of a short old man and says it's breakfast! He licks and sucks her breasts and sucks her pussy... Then he says he's checking how well her pussy sucks, and she allows the old man to insert his dick raw, and her tightness backfires and she cums inside him. Then, one after another, the caregivers allow him to insert their dicks, claiming that it's for the sake of improving their stamina, and they release their semen into her vagina.
