A mother and son indulge in forbidden carnal desires in the closed room of a bathroom. A virgin son's growing interest in women leads to an incestuous relationship, brought about by the mother's twisted love for her son. The mother cries out in pleasure at the son's first penis, and the son spits out all of his semen into her moist vagina. A mother and son lose themselves in the sense of immorality of committing a taboo, devouring each other's bodies.
