Old childhood love is suddenly at the door!

I'm lying on the sofa and resting, when there's a knock on the door and my ex from earlier is standing in front of the door, I didn't expect that at all. He sits next to me and looks at my crotch and immediately sees that I don't have any panties on, he just said that you can see something and I'm just at home, why do I need a panty. And why not continue where you left off. Somehow you always want to know what it's like with an old childhood love.
