My father-in-law, a monster with a super sexual desire, sees me with big breasts and is cute and gets fully erect...!! His sexual desire doesn't subside until I cum inside him, so he secretly jerks off and has an affair at home.

I got married and started living with my in-laws. The couple is happy and the family is on good terms. But a problem has arisen! For some reason, my father-in-law gets an erection every time he looks at me. The crotch is very bulky and makes a statement. W-why...? It's not my imagination, I always get an erection. Does that mean you're excited about me!? "This is what happens when I look at Misao-san...please, help me!!" Father-in-law is in trouble! My mother-in-law is there, and my husband is sleeping next to me...!! What's more, she says, ``It's hard to cum when there's a rubber on,'' and starts to fuck me raw!! Even though it's definitely not allowed inside, I cum inside her with such vigor!! My father-in-law, who is a super-sexual monster, can't stop ejaculating in one shot... This is a story about how my father-in-law, who was about to turn 60, secretly ejaculated 10 times inside me... Father-in-law, how old are you? (sweat)
