A rental mother suddenly appears to replace the mother who abandoned her son. Promising to act as a mother for three days under contract, she quickly wins the hearts of the lonely father and son. The son, touched by her gentle and beautiful care, reveals his affectionate side, finding comfort in ear cleaning and blowjobs from her. Meanwhile, the father grows increasingly aroused by her skilled tongue. One day, the father accidentally catches the son inserting fingers into the rental mother's genitals and frantically stimulating her. Overcome with rage and jealousy, the father forcefully ● her.
