Ask to come on her face

"I'm so close...Grace, I have a weird request." You say.

Grace takes you out of her mouth, holding your swollen member in her hands. Her innocent, studious face looks extra sexy with the smear of precum on her lips. "Yes?"

"Er...can I climax on your face?"

She screws up her face in confusion. "Why would you want to do that?"

Diana steps forward, "you don't have to say yes, Grace. Sometimes men find it sexy to see their semen on a woman, rather than ejaculating into a woman."

"Oh! I didn't realize you were so close to orgasm." Grace says, surprised, "I guess, yes, if you want to do that on my face you can. It might be less weird then doing it my mouth. How do I know when it's about to happen?"

"If you just stroke me with your hand and keep sucking me with your mouth, I'll let you know when I'm about to orgasm, then you can take me out and point me at your face."

Grace nods seriously, "got it."

Grasping you firmly in her hand, she begins pumping you again. You can already tell you aren't going to last long, and then she puts you right back in her mouth. You close your eyes and feel the world dissolve around you. She keeps her pace and her strokes, but it's the wet warmth of her mouth that is really driving you wild.

"Ok, I'm really close."

Her tongue wraps around you again, and she takes your head firmly into her mouth. She takes a deep breath and keeps you there, swallowing you down. She holds you in her mouth, pressing your cock against the back of her throat, not letting up. You feel the first wave of pleasure as her body heats up against you, and you know you can't hold back any longer.

"I'm gonna cum!" you moan, "ok, now!" and she slides your cock out of her mouth, pointing you at her face. The first jet of cum blasts out of you and splatters against her forehead. She smiles as she feels a stream of semen strike her nose and chin - she leans slightly to the left to avoid getting hit in the eye, and you continue to spray cum on her face. Grace continues to smile and gasp in fun surprise as the next waves of cum lands on her cheek and nose. You look down and see your cum dribbling from her lips, and she begins stroking you again, aiming your penis at her face as she presses it in against her cheek. She finishes you off with a few more strokes and a final squirt of cum, then she looks up at you, covered in cum with a big smile on her face. It feels fucking incredible.

You look over at the class, who are watching silently.

"How was that?" they collectively ask.

"That was a lot of fun," Grace says, "thank you for letting me experience that." You see a few nods of approval from the other girls.

Diana steps forward, "Joe, why don't you clean up Grace's face a little."

You oblige and walkover to her, kneeling in front of her. You start by licking the cum off of her nose, and the rest of the cum begins sliding off of her face, leaving only a shiny sheen. You keep stroking her face with your tongue, and she looks into your eyes as you lick her clean.

"I think you did an amazing job, Grace. I hope you got a lot out of that."

Grace smiles, "I did."
