Let him cum in your mouth

You feel his orgasm trigger, and you brace yourself. You're about taste your first load of come.

His dick twitches a couple of times in succession, and a slightly bitter, creamy substance shoots into your mouth. It's not pleasant, to be sure, but it doesn't really taste that bad.

You pause for a second, considering whether to swallow it or spit it out, but you don't really relish the idea of walking all the way to the bathroom with Ryan's semen filling your mouth. You quickly swallow it and feel it slide down your throat.

Ryan laughs. "Good girl!" he tells you and gently strokes your hair.

Just then you hear someone behind you.

"Excuse me, is there anyone here who could.. oh dear God."

You turn your head to see a thin man in a white shirt, khaki pants and wire rim glasses poking his head around the corner. He is staring directly at your face, which you only recently removed from Ryan's deflating cock.

He stammers, "I'll.. I'll come back later," and disappears.

Ryan chuckles, "Well, I bet that's going to be the most memorable moment of the expo for him."

You pick yourself up and tell him, "I've held up my side, now I expect you to hold up yours."

He nods, "Fair enough."

"Good," you reply.
