Hentai that you'd think exists already

Know what I'm surprised the Japanese haven't used as a plot device in hentai yet?

THE SHAKEWEIGHT.
For those who haven't seen the ad...


I mean come on, think of all the scenarios. Plus, added hilarity.

What other things have yet to be manga-ized? I'm sure there must be some stuff left...

What is this I don't even....

I guess...

Lamias...?

The closest thing Ive seen to a good Lamia in a hentai is the boob monster from Adventure Kid...

Check out this short one in my compilation torrent:
Aoki Kanji - Pretty Lamia [desudesu]

...or get it here:

the creator of that thing sure does a lot investigation about fapping...is there anyone out there who want to buy that stuff?

Well there's futa, but what about hermaphrodites who look like guys instead of girls?

There should be hentai about it.

There's a surprising lack of genderbents. I'm not talking "guy randomly turns into a girl" situation, but a genuine female version of given male character.

;-; that thing looks like it has sharp edges!!!!

But yes, the vibrating broom would also make for funny HP material. XD

I'd hate to drop that thing while using it "ouch" my toe!

Some guy that ejaculates THUNDERBOLTS

How unusual is this?
