HF-047 - Gaku Gaku Buru Buru Masturbation 240 Minutes

There's a science experiment where you shock a frog's leg and it twitches. This production feels exactly like that. You're forced to watch a specimen for four hours that just moans and twitches whenever its crotch is stimulated. It's not erotic in the slightest. The reason is simple: the staff in the room completely kill the performer's mood. There's zero passion or artistic intent here. After the main feature, there's even an ad where they basically say they don't want to work but want money.
