You keep doing it.

You trace a finger up and down her slit from bottom to top, and she arches her back and moans, "Yeah! I love that!"

A few of the girls have slid their hand inside their panties, and are gently rubbing their outer lips, while Sophia has spread her legs as wide as she can in this little desk.

"Oh, God, Joe," she moans, "You can feel how wet I am! It's running down my legs!"

"This is so sexy right now," a girl in the row in front of you says, "I want...to see him cum!"

"Me too," another girl says, "I'm so turned on!"

"Well, with my help," Diana says, "Joe can cum!"

You're straining to hold yourself back, but you are so hard. You wonder if you could cum from just the stroking alone. Diana resumes stroking you, harder than before. You can feel her strong grip on your shaft as she pumps, and you just...

"Oh, oh, oh, oh, oh, oh!" Sophia moans, gasping for air as her hips buck off her

seat, "I'm cumming!"

You and Diana both watch in amazement as Sophia writhes in her seat, shuddering and moaning, her whole body responding to your touch. You continue to tease her clit with your fingers and she seems to cum for a very long time. You can hear the other girls in class whimpering softly, and you realize they're touching themselves, too.

Hearing them whimper turns you on even more, and Diana can feel your renewed hardness with her hand.

"What do you think, class? Is he excited again?"

"Yes!" They all answer, and Diana smiles at you.

"Joe, I think it's time for you to cum. Let me finish you off, and you can show the class what male ejaculation looks like."

She begins stroking your cock faster and faster, her hand working down the shaft and then back up again. You groan and your muscles tense as you groan. With her other hand, she applies pressure to your stomach, holding you down as you tense. You are holding your breath, and you finally let out a deep, pleasurable, "Uhhhhhhh!" as you begin to cum.

"Ohhh!" the class breathes as they see your cum spraying out over Diana's hand, and several of the girls have opened their desks and are masturbating openly as they watch you climax.

"Wow, Joe, you came so much!"

Diana continues to pump you, feeling the rest of your cum flowing over your shaft and her fingers. The last stream of cum is intense, and you feel a sense of relief as it flows over you.
