HUNTB-703 “When I get a girlfriend, I’ll show you what to do. First, close your eyes…” My older playhood friend is a naughty meddler! An older sister who teaches SEX step by step

The lady next door has been kind to me since I was little, and she would sleep with me and talk to me about anything. I got a girlfriend too! When I told my sister, she seemed happy, but… “You have to do it properly so you don’t disappoint your girlfriend,” the older sister even advises on sex! And isn’t it just advice? Practicing here? I do as my sister tells me. But is this real sex rather than practice?
