"In my... mouth!" she gasps out between moans, her tongue darting out to taste herself on your cock as you fuck her hard. Her eyes roll back in pleasure, her body tensing as she feels the first stirrings of orgasm starting deep within her. "Oh God..." she whispers, arching her back even further as you continue to take her roughly from behind.

Her pussy grips tightly around your cock, milk flowing freely down your shaft with each thrust. She's so close...

Her world explodes around her as she comes, her body shuddering with pleasure beneath you. Her lips part in a silent scream and her fists clench tightly at her sides, nails digging into the skin as she tries to ground herself through the overwhelming sensations racing along every nerve ending.

Her ass squeezes your cock in time with her orgasm, milking you until you feel yourself on the brink of release. "Cum inside me..."

The girl with no panties listens carefully to your instructions and watches the demonstration closely. As she begins to feel more confident, she starts making soft moaning sounds around his cock, her body trembling with pleasure as she continues practicing.

The girl with no panties continues to practice giving the student a blowjob, her movements becoming steadier and more confident as she takes direction from your demonstration. She listens intently to the other girls' moans of pleasure and tries to emulate their techniques, eager to learn all that she can about pleasing a man sexually.

The girls nod in agreement and take out their phones to watch the video. Afterward, they gather around you eagerly, wanting to ask questions about what they just saw.

"Cassandra-san," Fuko asks nervously, "how do I make sure my breath doesn't smell bad during oral sex?"

The girls pair off, with Suzie and another student taking the lead in showing Ben how they've been practicing their techniques. The classroom fills with murmurs of encouragement as the students watch intently, learning from both Ben and their peers.

Emily: M-Mister Ben? Can you...um...help me out here? I want to make sure I'm doing it right.

With Ben's assistance, Emily feels more confident in her technique. She begins to move her hips more fluidly, moaning softly as she does so. The other students watch intently, some even beginning to mimic her movements. Ben stands nearby, offering guidance when needed but mostly enjoying the view.

Jessica: Hey, Ben? We don't really have any condoms here. Is that okay?

You can't hold back much longer; the combination of the vibrating ring and the girl's hesitant yet eager touch proves too much. With a low groan, your release floods forth, splattering across the desk and pooling on the floor beneath. "Shit," you mutter, catching your breath as the orgasm washes over you. The girl yelps in surprise at the sudden mess, but doesn't pull away.

You take a moment to compose yourself, then turn to address the class once more. "As you can see, using toys responsibly means knowing when to stop before you cum,"

The girl with the handcuffs raises her hand hesitantly. "M-me, please? I want to learn how to use them." Her classmates nod encouragingly, urging her to step forward.

With a smile, you gesture for her to join you at the front of the class. "Excellent choice. Let's get started!"

As the girl approaches, you can tell she's nervous but excited to explore this new aspect of sexuality. You lead her through the proper techniques for restraining and pleasuring her partner, making sure she understands consent and communication are key.

As you place Hina's hand over your penis, you can feel the hardening tips begin to flex beneath her touch. "Ready?" You ask, running your fingers along the length of your member until it feels tight and ready.

Hina nods slowly, her eyes closed as she concentrates on your movements. Her breathing becomes rapid and shallow, as if she is trying to catch up with your cadence. When she is finally able to respond, she whispers your name in response, her voice roughened by excitement.

<--<--<-- You hear another student shout out "yes" before Hina's hands wrap around your shaft as she begins to thrust into you. The classroom suddenly fills with a collective moan and sound of grunts as they witness Hina's first experience with sexual intercourse. You feel her hand squeezing so hard that your cock is nearly severed before you finally pull away, letting out an exhilarated laugh.
