YAL-102 The son's twisted fetish of only toying with me when his father is around　Ninomiya Keiko

A usual moment of family togetherness. The son, in his father's blind spot, roughly inserts a vibrator deep into his mother's vagina, causing her to collapse. The son watches this, excited and with an expression of bliss. In the bathroom, separated from his father by only a glass door, the son takes his mother from behind while threatening her to make his father sleep with sleeping pills. The mother complies, becoming the son's sex slave. Next to his father, who is deeply asleep due to the sleeping pills, the son begins to rape his mother, his eyes gleaming with lust... The mother reaches orgasm multiple times from the son's thrusts and has her vagina filled to the brim with semen, almost reaching her womb.
