WANZ-373 — Hey Little Brother! Be My Sister's Condom Practice Partner Yu Asakura

My sister, who just made her college debut, has a boyfriend! Having been taught that "contraception is a must," she starts practicing putting on a condom using me, her little brother! I get a full erection because she puts it on so awkwardly! I'll let you practice, so you'll have to treat me well♪ So we go for a handjob, a blowjob, and even sex! The condom comes off midway, and it turns into raw incest! ...But it feels good, so it's okay to continue the creampie sex, big sister♪
