ERDM-051 "No, I can feel it..." 70s, 60s, 50s! When I gave my mother a sexual massage, I got really wet... 4 hours - Shino Yanagihara

A son who proposes a massage because he wants to touch his mother's chest and buttocks. My mother thinks it's just filial piety and accepts it willingly, but she pretends to help me stretch and pushes my crotch against my body, and says something appropriate such as "my lymph nodes are swollen" and gropes my breasts and buttocks. The massage gradually escalates, and it develops into an erotic act without breaking down.
