Of course you do

There was no denying it.

You thought for a moment, and looked down at the sweet girl's head on your chest, and her hand on your cock. You knew what the lesson was going to be.

"Emma, have you ever watched porn?"

"Um, a little but," with a little laugh at how naive she had been,"I was always worried about getting caught,"

"That's okay, but well, porn is usually made for guys and there's something that happens a lot in porn because guys like it. They often finish with a facial."

"You mean... cumming on her face?"

"That's right. I think letting a guy cum on your face shows him how much you love his cum."

"Oh!" she said with a little surprise but, "that makes sense. It's really important that a guy knows I how much love making them cum, so I guess letting them do it on my face would show them."

You were pleased how easily that idea fit into Emma's head. "Exactly. I think that's something you should practice with me."

Emma pushed herself down the bed and leaned over to your magically-hard cock. You again felt her lips close around it. She was so eager to learn, you couldn't possibly deny her the opportunity.

"Bring that sweet pussy over here, Emma."

Emma pivoted around your cock, bringing her body on top of yours, and her pussy into view. You went in for another taste.

Having your face buried in Emma's pussy made her blowjob even more enthusiastic than it had been before. You felt her getting wetter as her mouth worked your shaft and a hand found its way to your balls. Your face was again covered with her wetness as you licked her with equal enthusiasm.

This was great, but Emma had made a request.
