HMN-734 My stepfather, a sex monster, gets a full erection when he sees my cute big-breasted body...! His sexual desire won't be satisfied until he cums inside me, so he secretly masturbates in an affair at home. Misao Oguri

I got married and moved in with my parents-in-law. We have a happy marriage and a good relationship as a family. But then a problem arises!? For some reason, my father-in-law gets an erection every time he looks at me. His crotch is really bulging and protruding. W-why...? I'm not imagining it, it's always erect. Does that mean he's turned on by me?! "This is what happens when I see Misao... Please, help me!!" My father-in-law is in a bit of a pickle! Even though my mother-in-law is there and her husband is sleeping next to me...!! And he keeps fucking me raw, saying "It's hard to get off with a condom"!! He absolutely doesn't want to cum inside me, but he keeps cumming inside me!! My father-in-law is a sex-crazed monster, so one ejaculation isn't enough... This is the story of how my father-in-law, who is almost 60, secretly ejaculated 10 times... Father-in-law, how old are you... (sweat)
