DVAJ-371 — A Life Of Incest With My Sister Who Lets Me Insert It Up To 3Cm, Aoi Kururugi

An older brother notices his younger sister Aoi's suspicious behavior. When he questions her, she says that she was practicing putting on a condom with his penis. Since then, he has been helping Aoi practice putting on a condom, but...it's too painful to leave him erect, so he asks Aoi to help him ejaculate. He can't endure just a handjob, so he goes for a blowjob and a pussy job...Finally, the two of them get to the brink of penetration, and they decide on a rule that "if the tip is only 3cm deep, it doesn't count as sex," and they start having repeated glans sex. Before long, just inserting the head of the penis isn't enough, and they start wanting to penetrate each other all the way to the depths of each other's vaginas. ★Click here to purchase the adult book "Aoi Kururugi Photo Collection"★
