DVMM-350 Sister and Brother TS Story: When a busty sister and her sexually active brother switch bodies, it's only natural that they'll engage in incestuous creampie action! Riho Shishido

A younger brother gets his hands on a tool that will make his fantasies come true, but accidentally switches places with his older sister while trying it out! His curiosity about a woman's body for the first time means he can't stop checking her body. The smell, the weakness, how quickly she can urinate from the urge to urinate, and especially... the sensitivity of the inside of her vagina is dozens of times greater than a man's!? The more he touches her, the wetter she gets, and he masturbates endlessly → his first orgasm with a man. He's curious about the man's penis. "I wonder what will happen if I put it in..." And then, finally, he has incestuous insertion. A story of an older sister (in a male body) and a younger brother (in a female body) who secretly have creampie sex without their parents knowing.
