HUNTB-703 "If you get a girlfriend, I'll teach you what to do. First, close your eyes..." The older childhood friend is so nosy! A sister who teaches you sex step by step.

The older sister from the neighboring house has been kind to me since I was little, even letting me stay over and listening to all my problems. Even I have a girlfriend now! When I reported this to her, she seemed happy... "Don't disappoint your girlfriend; you need to do it right," the sister even gave me sex advice! And it's not just advice? Practice here and now? I move as the sister tells me. But is this practice or real SEX?
