Roxy Ray has a well stretched and well used pussy. Here she engages in a bit of Urethral Play by sounding her peehole with a paintbrush handle.
Urethral Play and peehole stretching is quite addictive among those who have tried it. It is important to avoid infection and injury, so inserted items should be sterile and smooth. Purpose made urethral sounds are therefore best.
I tried this once. I sat in front of a mirror, naked, and practiced giving head with a toy. The whole time, I couldn’t meet my own eyes. What that says about me, I’m not sure, but I am sure that it says something.
