Matsumoto's experiment

Matsumoto's experiment by Eofan

"Ohh someone really wants to test himself." *wink*

"Start by slapping your buttocks. Smack each one of them 20 times really hard!"
"Now take the ruler and hit them, 10 really painful slaps for each one!"

"Set the beat to 180 and jerk of for my tits for one minute!"

"It is so arousing to see you squirming with pain and pleasure."

"Hit your balls 15 times like you hit your buttocks... very hard and painful."
