1 Introduction(04:57)
A teacher who likes to experiment invites me to a naughty experiment.
I was told that I could feel very good just by taking it quietly.
I agreed without hesitation.

This is the first time I’ve seen this movie.
The experiment begins.
If you can take it all the way to the end, you will get a pleasant ejaculation and admission to the school.
Follow the instructions without peeing your pants in the process.

□ Advance preparation
With a briefing about the penis.
Encourage an erection by lightly shimmying.
Ear maintenance is also added during the process.

□ Experiment 1: Speed
This is an experiment in which you shimmy to the speed of an electronic sound.

□ Experiment 2: Heat
This is an experiment to generate frictional heat by shiko shiko.
Put the rod in the teacher’s mouth and measure it.

□ Experiment 3: Durability
This is an experiment to make you endure the desire to ejaculate in a short time.

□ End of experiment
This is an ejaculation using a special concoction.
