Everyone who had been watching from behind started talking.

"Christine's so hot. Peter made the right choice picking her."

My face went bright red. I didn't know what to say.

Luckily, Peter told us to officially start the class right then.

The whole point of the Wife Training Camp was to teach us how to become proper wives and train our bedroom skills so that our husbands would stay completely devoted.

After running through the theory, Peter moved on to the hands-on part.

He had me kneel on all fours on a yoga mat so the other students could watch how to shake their hips until they jiggled like Jell-O.

I had my back to everyone. The men and women in the room were all craning their necks to see.

Having a bunch of guys stare at my rear made my whole body burn, but weirdly enough, it also got me excited. That excitement made me feel hot all over. I stuck my bum up high and started shaking it hard, like I couldn't even control myself.

My two cheeks, squeezed tight by my yoga pants, bounced up and down so fast that they looked like perfect Jell-O.

The men in the room couldn't take their eyes off me. They had never seen anything like that.

"Peter, we can't see that well. Can we get closer?" the people in the back said.

Peter said yes, so they all crowded in right behind me to get a good look.

Having that many guys stare at me from so close made me even more embarrassed. And then, without meaning to, I felt a warm rush leak out of me.

A wet spot spread right across the middle of my yoga pants.

The husbands behind me got even more worked up.

That was when Peter said, "Pay attention, everyone. Christine's form is the best."

I moved my body as hard as I could. The hotter I got, the more I felt like I needed someone to fill me up.

"Sh-should I go faster?" The words came out of my mouth, all breathy and sweet.

Peter looked at me, totally turned on. He put one hand on my hips to feel the vibration. The warmth of his palm against my skin made every pore on my body open up.

"Get a little dirtier for me. Use both hands and squeeze your tits."

I pushed myself up a little and pressed my hands against my chest, rubbing like crazy right through my shirt.

Doing something like that in front of all those people only made me more turned on. The need inside me just kept building.

Peter kneeled down behind me, right where my bum was sticking up in the air.

"Next, I'm going to show you how to do it from behind."

He reached around and replaced my hands with his own, grabbing my breasts hard and squeezing.

I had never let anyone touch me there except for Matthew, and definitely not in this position.

The thin fabric of my pants was all that was left between us, and I could feel every inch of him pressing up against me.

If I hadn't been wearing pants, he would've been inside me already.

An itch started spreading through my whole body, making my bones ache from the inside out. All I wanted was for him to throw me down on the floor right there.

Soft little moans kept slipping out of my mouth without me meaning to. My whole face went flushed.

He grabbed my chest with both hands and pulled me back against him.

That pressed us even tighter together. I could feel him pushing through the yoga pants, just barely starting to get inside.

Peter arched his back and said, "Start moving your hips now."

I started shaking my bottom like crazy, rubbing hard against his body.

He just kept getting bigger and harder.

"Faster. Even faster," Peter said, his hands never stopping their squeezing.

My ass was like a little motor, going faster and faster. The itch between my legs turned into a fire. I completely lost myself in it.

And this was just through our clothes. If we weren't wearing anything… I couldn't begin to imagine how good that would feel.

The people watching couldn't look away. It woke something up in all of them.

A couple of them couldn't help themselves. They grabbed their own wives and dragged them off to the bathroom.

Then they came back looking like it still wasn't enough. Their wives had no idea how to move the way I did. The way those guys stared at me, it was as if they wanted to eat me alive.

Peter was behind me, and I had been grinding on him so hard that he could barely hold on. He grabbed my body and started moving gently against me.

The itching in my body kept getting worse. I swear, if it weren't for my pants, I would've already hit my peak.

But then a bell rang, sharp and clear. Class was over. Peter pulled himself away from me reluctantly.

He announced the end of class and said we would pick up again tomorrow.

I held it together through the itching and finally made it home.

Matthew took one look at my face, all needy and unsatisfied, and immediately started wondering if I had done something with the teacher.

I said no, obviously, and pulled him straight to bed.

All eager, I climbed on top of him and rolled my hips hard, grinding against him to scratch that itch.

Matthew had never seen me move like that. He didn't last long. He just laid there looking up at me, totally blissed out. At that point, he didn't care what I had or hadn't done with the instructor.

The next morning, Matthew left early for work. My body started itching again, but no one was around to take the edge off. I was losing my mind.

Finally, night came. Time for the training camp.

I made sure to wear a loose skirt with no underwear underneath. That way, it would be easy for Peter to just flip it up and go.

But what I didn't expect was that Peter had changed the lesson plan. No more getting on all fours and rolling those hips.

Instead, he switched things up. We had to lie on our backs, brace ourselves with our hands on the floor, spread our legs, and move our hips up and down.

Peter asked me to come up front and demonstrate to the class how to use the right muscles.

I wasn't wearing anything underneath. With all those eyes down there, everyone would see everything.

So, I hung back, not moving.

Peter looked confused and asked if I was still sore from yesterday.

I shook my head. No way I was telling him I was going commando.

Peter kept pushing me. "Christine, the class won't work without you. Just practice with me, and I'll waive your tuition."

That got my attention.

The tuition wasn't cheap. It was three months of Matthew's paycheck.

So I walked up to the front, heart pounding, sat down on the yoga mat, and squeezed my legs shut as tightly as I could.

Peter said to the class, "Pay close attention to what comes next. Watch and learn."

Then he pressed his hands against my knees and pushed them apart.

The whole place erupted.

People craned their necks, trying to get a look.

Even Peter seemed caught off guard. He just stared down at me, his Adam's apple bobbing hard.

With all those eyes on me, I felt embarrassed, but beneath it, there was a faint, unexpected thrill.

I mumbled, "I was in a hurry today, so I forgot to put underwear on."

I was trying to cover up the shame of it all.

No one said much after that. They just sat there, quietly taking in the view.

Peter pushed my legs open wider. "Watch closely. I'm going to demonstrate."

He had me lean back on my hands and tilt my head up toward the ceiling. My legs spread wide under his grip, exposing everything. You could even see the deepest part of me.

The tension made me clench. Underneath, I could feel myself opening and closing, like it was breathing.

"Now move your whole hips. Up and down. Faster. Faster."

I moved like my life depended on it. The excitement climbed up my spine. The wanting inside me peaked.

Water splashed from me as I moved, spraying everywhere.

The men couldn't take it anymore. They stared between my legs and lunged right on top of their wives.

Peter's eyes went glassy. He couldn't help himself anymore and pulled down his pants. A massive length sprang out right in front of me, swaying and incredibly tempting.

He lay down underneath me, took aim with his tool, and lined it up against me.

"Everyone's excited today," he said. "I'll walk you through it live. Follow my lead."

Inside me, I was already drowning in desire. The moment I saw his size, I lost it.

I sucked in a breath, dropped my weight down, and sank onto him hard.
