After passing the entrance exam for a certain famous national university, I was staying with my relatives, but now my sperm is being targeted by the wife of the family, Aya-san, and her sister, Asahi-san! Apparently, my mother-in-law is putting a lot of pressure on me, and she's worried that she might have to leave the house if things continue like this, so she's chosen me, a young girl with the same blood type as her... This threesome where the frustrated sisters straddle me and compete to squeeze out all my sperm, shaking their big asses with incredible vigor, is a must-see!
