He stopped me again, when I reached for the blouse, by leaning forward and grabbing my wrist. "Iku, the first sequence the professor wants to record is a 30 second lap dance. He wants us to practice two versions, one while you're wearing panties, and one without..."

"He... he wants us to practice? Um, when will he do the recording?"

"He's going to let me record them, then he'll upload them onto Twoku's microcomputer from yours. It's a test to see if we can work together. He pulled me closer, so my knees were touching his. "Iku, climb on my legs as if you were the Doll. I want to see what your body movements look like."

"Can I put my blouse on first?"

"No, Iku. I want to see how all parts of your body move."

The inexperienced lad was full of bullshit, but I accepted that I was going to have to work with him on the new sequences. What was worse was that the professor had been so wrapped up in his work, he hadn't bothered to warn me about the changes and Koji's new role.

I had noticed, while Doctor Konishi was away in London, for ten days, that the professor was more absorbed in his work. Finding out they were a pair explained his behaviour.

The professor had mentioned lap dancing as a possible sequence, but never tested it. What Koji was asking for wasn't a difficult manoeuvre. My pussy was covered so I wasn't quite as embarrassed as I might have been as I edged forward on tip toe until I was able to sit on his knees. I leant slightly forward and placed my hands on his shoulders.

"I'll play some music when we're in the new suite. For now, just imagine it and give me some of your moves."

"Um, I'm not a very good dancer, but I'll try." I had seen lap dancers in the movies, so I tried to mimic what I had seen.

I watched his eyes as I gyrated my body without leaning too far forward. He was focussed on my jutting tits mainly, which wasn't surprising because they were moving quite close to his face. Suddenly he couldn't resist them any longer and gently placed his hands beneath them and thumbed my hard nipples.

"Heh," I said. "That's not necessary in a practice."

"Iku, are you telling me that the professor never fondled your tits or shafted you whenever you got excited?"

"I'm not excited, Koji..."

"Your nipples are as hard as bullets and I bet your pussy is hot and wet."

He dropped his left hand and placed it on the stretched gusset that partially covered my splayed labia. Unfortunately, the narrow strip of cotton couldn't fully contain my puffy major lips, so his fingers made contact with some of my pussy flesh bulging beyond the leg elastic.

"Just as I thought. I can feel your sex swelling and your panties getting damp."

The modifications to my pussy made it hypersensitive, so when he rubbed my lips and pressed his middle finger against my clit, a quiver ran through my body. I hadn't really recovered from the earlier demonstration when the man of my dreams, the billionaire tycoon, Toshira Sasaki, thrust a dildo into my quim.

I grabbed his arm but couldn't budge his fingers. "Koji, I always get hot and wet when I'm doing stuff like this, it's the result of the changes they made to my labia. It's not because I'm getting off on giving you a lap dance."

"Iku, put your hand back on my shoulder and continue dancing."

It was a firm order which I reluctantly carried out. "Please remove your hand then, Koji."

"Get on with it, girl. I want you to enjoy yourself."

As I increased my movements, he increased his, clearly trying to get me excited. As soon as the pleasure overcame my annoyance, I closed my eyes and tried imagining I was sitting on Toshira's lap. The billionaire was one of the most eligible bachelors in Japan and virtually every girl in the company fantasized about him.

It was a thoughtless thing to do because I didn't see Koji move forward and slip his free arm behind me. Before I knew what was happening, he was sucking my right nipple and holding me closer. Like my clitoris, my nubs were hypersensitive, and I loved them being sucked. I slowed my body movements, but I couldn't wrench my nub from his mouth.

"Mmmm," Koji murmured before releasing it and trying to dock with the other one.

"Koji, what are you doing..." I complained, lamely.

"I've got to do both. Those are the rules." I wasn't able to stop him pulling my body toward him and latching on to my pointy nub.

"You're making the rules up..." My voice trailed away as the twin attack on my sensitive nubs triggered a series of thrilling sensations to wash over me.

Then, just when I was approaching a pre-orgasm state, he released my nipple and stopped rubbing my clit. "Sorry Iku, but we're going to have to continue this later... finish getting dressed."

I backed off his legs and tried to act relieved. My heart was hammering in my chest and my face felt flushed. I didn't want to show him that I was enjoying myself. That would only encourage the impulsive young man.

Once again, I found myself removing my panties to an audience. It was only one person on this occasion, but when I volunteered to have a Doll made in my image, I didn't realize that I'd be undressing so many times in front of so many licentious men.
