Perfect mistresses deserve well-trained subs. Are you up for a stroke challenge to prove your worth? Repeat tries are welcome. Prepare to feel sexual frustration, and by stroking to this clip, you agree to participate. As a professional, I admit no sexual joy in challenging you to stroke along to my body and words, please know this is strictly for research purposes... follow along to my words EXACTLY, and showcase your precision cum countdown ability. It’s imperative for the study that you cum EXACTLY when I say, no sooner no later. Great clip.
