Filling my (sisters best friend)/(neighbor)/(childhood babysitter) with baby batter. [MF]

Obligatory Prelude:
My childhood babysitter also happened to be our next-door neighbor and my older sisters best friend. My family and the neighbors family became friends over the years, and to this day we still have the occasional BBQ or pool party with them.

It all started one day when I was going to pick something up from their house (I believe a tool that needed borrowing for fixing something or other?) I saw her and we were making small-talk, the typical how have you been, etc. Then I started to notice something about the way she was speaking, almost a sultry tone. It was something I hadn’t heard before in the years I’d known her. She laughed way too hard at a stupid joke I told, and was telling me how good it was to see me. I’m no genius when it comes to women and what they want. I’d always been the nerdy kid, and try as I might, I’d only successfully gotten laid on a select few occasions. That didn’t mean I wasn’t going to shoot my shot!
