Every man's dream- the ability to have sex with a woman without her even knowing it. Wait.. What?
Mie Naito is your standard creeper but somehow you can get around it (it must be the hilarity of the circumstances).
From some random sensation of being poked in the woo-hoo at a bath house in the water to a ghost dog doing naughty things, the Invisible Stud has some fun with the ladies in a comedic manner that entertains the viewer as well as satisfies their porn needs.
Overall a good quick watch that is recommended.
