MRXD-020 I became my son's pet ... Mayumi Imai

Mayumi, a talented and beautiful mother who lives peacefully with three family members, has had some troubles recently. It's about the fact that my only son, who is very important before taking the exam, seems to be absorbed in something like masturbating in his room recently. One day, the anxious mother goes to her son's room. Seeing her child who grabs a hot, engorged blue meat stick and panting painfully, Mayumi just supports her child's sexual processing because she loves it. But that was the impetus for Mayumi's fall.
