Start pegging him while you continue to stroke his tied-off pole
From Create Your Own Story
You reach over, lube up and secure your strap-on, and slide into him. You hand keeps moving on his swollen pecker.
"Uhhhh... ooooh..."
You lean down and give him a quick kiss. Then you build your rhythm, speeding up until your sliding in and out of him a fairly fast pace. His frustrated moans are turning you on.
You speed up a bit more and bring yourself to climax. His cock is throbbing and purple. You take off the strap-on, clean it, and stroke him a little bit longer.
He manages, with an effort, to focus long enough to gasp out, "Mistress... please..."
You remove the twine from around his balls.
