My stepmother mariko sada came to Tokyo from my wife's parents' house to take care of my pregnant wife. Our relationship was good, but it turned sour when i tried to have sex with my pregnant wife, and i was ordered to abstain. One day, seeing me listless during my abstinence, mariko sada offered me a massage. I couldn't resist her exposed cleavage and got an erection. Noticing this, mariko sada suggested with a seductive expression, "should i massage this too?" and made a wicked proposal.
