Yes!

Gradually increasing the pressure of her suction and adding slight flicks of her tongue against your sensitive tip, Grace quickly learns how to make you moan with pleasure. Just when you think you can't take it any longer, she releases you from her mouth - only to start again moments later. Her wet heat surrounds you as she bobs her head up and down, taking more and more of you into her mouth each time. The pleasure continues to build until finally you reach that blissful point where all thought has been replaced with pleasure, and you let out a loud moan as your orgasm overtakes you.

Your cum explodes into her mouth, and she swallows it greedily. You feel a rush of pleasure as she continues to gently suck on your cock until the last few drops have been taken in.

Grace looks up at you with a satisfied smile as she gently licks away the remaining drops of cum from your shaft. You can see in her eyes that she's enjoying this experience just as much as you are. As Diana gives her an encouraging nod, Grace continues to kiss and lick your dick until every last drop is gone.

"What do you think, Grace?" Diana asks with a smile, "What will your notes say about today?"

Grace smiles thoughtfully, glancing at her notepad, then back to your cock.

"To be honest," she answers, "I don't really know. I've never felt quite like that before. I didn't know that it would be so warm and, well," she pauses, glancing around at her classmates who are watching the exchange, "I didn't know that it would be so good."

"Girls," Diana says, "I want you to go back to your seats, and think about what you've just learned. As you were touching Joe, think about how his penis felt in your hands, and how his body reacted to your touch. Think about what you did to give him pleasure, and how you felt when he climaxed. I want you to jot down notes about the experience, and I'll give you some more time to write down your thoughts before we continue the lesson."
