Finish him off in your mouth

Deciding it's best not to miss the start of the class, you start sucking him faster and start stroking with your right hand vigorously. He starts tensing up, you increase in vigour even more

"I'm .... Gonna... Cum!" he says breathlessly

Just as he finishes saying that, he shoots straight into your mouth. You keep sucking as he shoots more into your mouth. There's almost to much, and small amounts dribble from the side of your mouth. When he finally stops, you pull out and start swallowing his creamy cum down.

"Wow... you really haven't done it a while" you say, once you finish swallowing. You then lick his cock clean as he pants slowly.

"you were good, really good" he smiles.

Once he'd pulled up his boxers and jeans, and you had put your hoody back down, he went in for a quick kiss. You let him, he is really nice, and maybe you could get your end of the fun out of him later
