[F] I’ve been secretly stripping and getting off just out of eyesight of the construction workers at my apartment

My (26F) building is getting repainted so there have been workers on site for the last two weeks. Last week there were two painters outside of my window when I got home. The window right in front of them has an accordion paper shade that only lets through faint silhouettes.

I don’t know what possessed me.
I’ve never felt an urge like this before.
I stripped to my bra and panties and started touching myself in front of them. Very lightly, I wasn’t really trying to get aroused, I just thought it was kinda fun. I could hear them speaking to each other inches away from me—they had no idea.

Then I slid my bra down around my waist and started playing with my nipples. I have very sensitive nipples and usually don’t play with them ever. But i felt like I had to. I licked my finger tips and played with them and it made me so horny. I knelt on my bed right in front of them and played with myself some more for a few minutes.
