The girl next door has been kind to me since I was little, and she would stay with me and listen to my problems. But now I have a girlfriend! When I told her, she looked happy, but... "You have to do it properly so you don't disappoint your girlfriend," she said, and even gave me some sex advice! But it's not just advice, is it practice here? I do as she tells me. But is this real sex rather than practice?
