Suggest using a brown pen

You point to the brown pen.

"Did you say that it can create a skin if she uses it on herself?"

"Yes, you will shed the second skin like a snake" - said Marie, twirling the pen in her hand.

"How about..." - you're thinking. "Did you say that you didn't have real sex?" - Marie looked sharply at you, and nodded slightly.

"I propose to arrange an exchange of bodies! You will create your skinsuit, and I will create mine. When my boyfriend comes, you can have sex with him"

Marie looked at you in surprise, then broke into a smile and licked her lips.

"Heeeey... sounds pretty good..."

You crawled up to her and grabbed her crotch, looking into her eyes you said:

"Let's do this before my boyfriend comes back..." - you plunged into a kiss.

Marie grabbed your breasts while continuing to kiss you. She hit you on the back with something. You felt a little strange feeling, as if you got a little fatter.

Marie unbuttoned your black bra. Wrapping her arms around your neck, she opened the hole and began to peel off the skin of your head. You saw a little red inside of the mask. It's like you've been reborn. Your mask was now hanging around your neck.

"How does it feel, Kate?" - asked Marie excitedly.

"Ah... it's an amazing feeling. It's like I was born again..." - you touched your face.

"Keep undressing, while I take off my zentai" - Marie began to undress rapidly.

You dug behind your back and pushed the gap even wider. Your second skin has settled on you a little. You pulled your arms out of the sleeves, now the suit was lying on the bed to the waist. The suit looked like it was alive from the inside. You started pulling out your legs without taking off your panties, you clearly felt a cool breeze on your renewed skin. The suit seemed to lose its grip, and you easily slipped out of it. Now your shell was lying lifeless on the bed. You looked at Marie, she was pulling the black zentai off her mesmerizing legs. You noticed several scars on her body.

"Where are the scars from?" - you asked.

"Well, you know, not everyone is like you" - Marie replied with a grin.

She was actually very slim and at the same time toned. Her young breasts jumped with every action she took. There was some physical strength in her, but you were more prepared.

Throwing zentai on the bed, she took a pen and hit herself in the stomach. After a while, she took off her mask, and then the whole skinsuit. You looked fascinated at this process. She was beautiful, and the fact that she took off her copy turned you on. It brought you out of your trance that she threw her skin on your lap. And she pulled your skin to herself.

"Well? Shall we begin?"
