I looked at David sternly. "Well, it's too late to do anything about it tonight. But tomorrow, I want to take you to see a friend of mine, OK?" I was being intentionally vague.
"Who?" he asked tentatively.
"Just a friend," I said coyly.
His hesitancy grew. "Um, I'm not sure, Terri."
I bit my lower lip and smiled, "David," I said to him sharply, "You were a very bad boy. I asked you not to cum and you did anyway."
He was looking more and more confused. "I didn't think you were, you know, serious," he protested.
"Of course I was serious David." I added just a touch of disappointment to my voice. "I really had hoped you'd wait for me." I slid my hand along his leg, slowly tracing his thigh until I reached his crotch. I touched him gently.
"I want to see you squirm, I want to hear you whimper, I want to hear you beg, and maybe even something more," I felt him grow harder in my hand, so I began stroking him slowly again.
"What do you mean 'more'?" he queried.
"Oh, you'll find out tomorrow," I teased, smiling as I continued stroking him.
"Now do you think you'll be able to keep your hands off yourself tonight? Or do I need to give you a little help?" I asked him, growing more playful. I twirled my hair with my finger, watching him squirm a little.
"What kind of help?" he asked.
"Well," I said seductively, "I could always tie you up." I felt his cock stiffen at my invitatio and I giggled. "I see you like the idea," I continued, teasing him a little.
He had closed his eyes and was now arching his back a little, pressing into my hand. The more he pressed, the less I rubbed, pulling back as I sensed his hunger growing. Finally, he reached up, grabbing my hand and pressing it into his cock.
"Tsk, tsk," I chided him, laughing, "You don't do that David. That's being a bad boy."
He blushed, squirming a bit, and swallowed hard, "Please," he said softly.
