A younger brother gets a tool to make his fantasies come true, but while trying it out, he accidentally switches places with his older sister!I can't stop checking the body because I'm curious about the female body for the first time.The smell, the weakness, the speed from the urge to urinate to actual urine, especially...The sensitivity of the inside of the vagina is tens of times more sensitive than that of a man!?The more you touch it, the wetter it becomes, the more you masturbate → The first time you have an orgasm with the opposite sex.What I'm curious about is the man's penis.``I wonder what will happen if I insert it...'' And finally, I insert my incest.A story of an older sister (male body) and younger brother (female body) who have creampie sex without telling their parents.
