Risky embroidery

My secret lockdown project has been embroidering a pair of panties with "ask me for a blowjob" across the butt.

So far I've worn them out under a knee length skirt a few times.
I've only once had the guts to wear them under a really short skirt. The scariest bit was walking up a flight of stairs by the supermarket, there was an older guy behind me but he didn't say anything. I wonder if I would have gone through with it if he asked me?
