You hide her zipper

"Let me hide the zipper with this cream" - you show her the tube.

She turns her back on you.

You squeeze a beige substance onto the zipper and started smearing it on her back. She trembled at your touch. Although the skin seemed artificial from the outside, but it felt like real. You smeared cream with your fingers along the entire length of the zipper. After rubbing harder in one place, you noticed that the cream does not rub off. It has already dried and hidden the zipper on the back. You were surprised by the quick effect, and then looked at your fingers, which became even smoother, and you couldn't peel the paint off your finger. You have decided that then you will look for how you can wash off this cream.

"You can look into the mirror now"

She turned to you and then ran to the mirror. She was examining her smooth back. She ran her hands down her back as if enjoying herself. You have decided to start your transformation so far and have started taking off your boxers. You picked up your men's suit when suddenly a gentle hand covered your mouth, and the second grabbed your penis, which was still standing. You groaned and tried to take your hand away. Turning your head, you saw a twinkle in her lifeless eyes, she began to masturbate you. Your knees are shaking.

"Mpppffhhhh! Stop, stop...", you were able to escape from her grasp.

"What's wrong with you? Can't wait to get started? Let me put on my suit, you can put on the rest of your clothes for now."

She folded her arms and just stood there looking at you. Apparently she'll be watching you get dressed. You took the suit, inside it was the same beige color. You stick your foot inside, feeling this cool stuff. It doesn't seem to be latex, because it is softer, but for some reason it was cold inside. You matched your toes to the toes of the suit. And they began to pull the suit up to the hips. Next, you had to pull the artificial skin over your penis. The pocket was very tight, as if you were pulling a condom on your penis. Then you experienced pain because a small tube entered the urethra. Apparently, so that you can easily urinate and not only.

"Damn, it was unexpected" - you thought.

You looked at your sister, who started rubbing her crotch while looking at you. Your penis started to get up again, at the same time you checked how your artificial penis works. You tried to jerk him off, and it was amazing, the skin was very elastic in this place. She came up to you and started pulling the rest of the costume on you. You put your hands in the sleeves of the suit. While she started to fasten your back.

"Well, from now on, are we both going to be silent now?"

She took you by the cheeks, nodded and kissed you. You kissed her back, on her artificial lips. Then she took the mask and dived inside. You had to swallow a huge gag, but when you reached the end you were able to close your jaw, now you understand how you felt her lips in the mask. The gag ended with a tooth mold. You aligned the breathing tubes, and then you opened your eyes and saw the light.

You couldn't make a sound. To your surprise, you saw almost as well as without a mask. When suddenly you felt the tension. Your sister has completely buttoned up the suit. You turned to her and wrapped your arms around her waist. You looked at each other until your lips touched each other again. You stood and kissed with your artificial lips. It turned you both on. Your cock got up again and rested right in her artificial pussy. She stroked your back until she felt something metallic. She pulled away from you and reached for the tube on the bed.
