I [34M] let her see it through my grey track pants

I live in a shared apartment block. When I take the trash out I have to walk through communal gardens to get there. When I first moved in I’d see this woman [24ish] a few times when walking past with my recycling, she’d be sitting outside on phone and smoking the occasional ciggie, and we’d smile at each other and say hi. After a year or so we’d maybe just chat briefly about the weather or the gardens, and I’d often see her sneak a look at my crotch area, as I’d usually be in my PJ bottoms or track pants. I liked it. Recently when I’ve seen her out there before I take out the recycling, I make sure I’ve got a soft boner in my pants so the outline is visible. Now she always sneaks a look and smiles. When she has her sunglasses on I know she’s looking at it the whole time. I know she wants to pull it out.
