Theresa listened to the music blasting from her headphones as she waited, blindfolded and bound at the wrists and ankles. She was on all fours, her head resting on a pillow, arms folded neatly below her, fuzzy pink cuffs keeping them bound together. Her exposed ass and pussy swayed back and forth gently as she waited patiently on the ottoman in the center of the living room.
I watched on the security camera as a gentleman in his late 50's parked and got out of his Mercedes. He walked over to our door and gently opened it as instructed. He closed and locked it behind him, then looked me in the eye, then down at Theresa's large ass. She felt the rush of air as the door opened, and began to wiggle with excitement.
The man's crotch began to stir as he stepped forward. He undid the button and pulled down the zipper on his slacks, revealing a decently-sized white cock, with gray pubes neatly trimmed. It was growing larger by the second as he looked back at me.
Obediently, I got down on my knees and sucked his cock into my mouth. He tasted slightly salty from the precum leaking from the tip, and grew extremely hard almost instantly. I pulled back smiling, and pushed him towards Theresa.
He placed his hands on her hips as we'd agreed, spreading his legs apart enough to allow me to cup his balls and use my fingers to help guide him into Theresa's now-dripping-wet pussy. As he slid in, she moaned loudly and pushed back hard enough that I had to brace the man to keep him from getting knocked back. He began to thrust as my finger slid down the shaft of his now-glistening cock and found Theresa's engorged clit. As I rubbed, she moaned louder and very quickly began to cum. This made the man groan, and before long I could see the telltale sign that he was filling her with seed, as his balls bounced on my wrist and he pushed himself as deep in as he could. This of course made Theresa cum again.
As he pulled away, the man let out a woop and a grateful sigh before leaning down and kissing her ass, thanking me, and heading back out to enjoy the rest of his day.
