A Tune

You come down from your high, gently bobbing in ecstasy as you dribble your last bits of cum, your cock slowly returning to flaccid state. You look down to see him smiling a wicked grin.

“We’re not done yet. You’ve brought me a toy to play with, and I intend to try it out.”

He parts his lips and begins to whistle a low tune. A tingling sensation passes over your groin and you instinctively grind against him. His whistle begins to crawl up the scale and you watch as your cock begins to raise again. He maintains a note, making you shiver as your aching red member throbs over and over. Suddenly, he jumps to a high note and your balls shoot up, blasting a string of cum onto his stomach.

“Perfect, just what I was hoping for.”
