My obedient little sister... "Kotone" is extremely serious and pure... but at home, she's my sex toy. Her body drenched, bound tightly with hemp ropes... her lower half growing more sensitive. "For my big brother's sake..." she happily serves unknown men's penises... Each time she's bred, she feels joy. "I want to be more connected with my sister..." Her masochistic love accelerates. The entirety of my twisted sexual preferences.
