One day, a calm and blissful smiling fifty mother who spends her ordinary daily life witnesses her oversleeping son squeezing in the morning. A fifty mother who indulges in masturbation because she can't stand the ripe mako who gets wet with her strong-grown son herself. The son who peeked at such a mother's foolery can not suppress the distorted excitement and devours the soft and ripe plump body. A fifty mother who shakes her big breasts and ripe meat and ascends to heaven many times in a forbidden fellowship.
