MDTM-105 My sister who loves to be tied up and obey me, Reihime Kotone

My obedient sister... "Kotone" has a very serious and neat personality... but at home she's my meat urinal. The body that gets wet with the hemp rope that bites in ... the lower body that becomes sensitive. She says, "If it's for your brother's sake..." she happily serves the penis of a man she doesn't know... A younger sister who feels joy every time she is raised. "I want to be more connected with my sister..." A masochistic affection that accelerates. The whole story of my distorted propensity.
