I made a guy cum prematurely with a vibrator

[F24] Recently, I have been loving making this guy cum prematurely. It is so fun watching him squirm and desperately try and hold in his cum.

This time I decided I would make him cum by using my vibrator on his cock. His dick was hard before I even pulled down his pants. I saw his dick twitch once he saw me pull out the vibrator.

I started with a slow gentle setting and brushed it all over his cock. I went up and down. He moaned with pleasure.

I switched to a more intense setting and put the vibrator directly on the underside of his dick. Not even ten seconds later his cock exploded with cum.

He looked down with a red face and embarrassed. I made sure he knew it was okay by licking up all the cum.
