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

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?
