Your mouth, please.

"I could come so fast just by fucking you right now," you tell her, "But I really loved the feel of your mouth wrapped around me earlier today. I'd love to feel that again."

"Let's take it full circle," your friend agrees, "I hate to say this, but you're gonna have to pull out of my now."

You sigh as you slide your still massive member out of her soaking, satisfied slit. The class makes a little side of surprise and intrigue as they see how your cock is even bigger and redder than it had been before.

Diana takes a moment to step back into her panties. You make a disappointed sound and she laughs. "We have a strictly business casual dress code at this school," she tells you with a wink, as she pulls her slacks back on, "but if you want something to look at, maybe one of the girls would undress for you again?"

"I only have eyes for you right now," you respond.

"Aww," your friend remarks playfully, "well, then feast your eyes on this."

She locks eyes with you as she pulls a chair up towards you, pushing you gently back against the desk so you have something to lean on. She takes your cock in one hand and begins slowly sliding up and down its length, using her pussy juices to lubricate the movement. It feels amazing and you thrust into her hand.

"Not yet, not yet," she says, leaning forward and running her tongue softly around the edge of your cockhead. You swear under your breath, and push forward, trying to find her mouth. For a second she moves back, and all you find is empty air, but then suddenly a wet warmth engulfs you as she slides you into her mouth. She takes you in firmly, covering every inch of your cock and sucking it. It feels incredible.

You slide your hand around the back of her neck, still sweaty from her earlier exertions, and guide her as she sucks up and down your cock, letting you mouth-fuck her faster and faster. Within short moments you find yourself losing your mind, hearing the sloppy spit sounds as she sucks you, feeling her tongue rapidly swirling over your cockhead every chance she gets.

Before your realize it you're about to cum! You let out an illegible sound and start blasting into her mouth, incredible waves of pleasure pulsing through you. She pulls you out of her mouth but keeps pumping with her hand as you spray gouts of white ecstasy all over her face.

"He's orgasming!" She exclaims redundantly as her face is covered with semen, "Watch him! It's amazing!"

She lets them watch for all of two seconds before taking you back into her mouth. The renewed sensation inspires a second, smaller orgasm, pulsing three, four, five more times rapidly onto the moist heat of her tongue.

Finally, you stop, hand still resting on the base of her head. She continues gently sucking for a few more moments, then sits back up.

You look at each other for a long, timeless moment, her satisfied, dripping wet face beaming at you. You can't wait to do this again.
