Nut Crack Device [English], by Matsumoto Mitohi
Mommy, help, I’m falling to the dark side, more with every year, now I’m starting to genuinely love futanari and gender bender!!
Here’s a fresh and high quality (but maybe I’ve stopped being unbiased, argh) gender bender release, using a nice plot device.
Hear me out: a young man is selected to shoot a scene with his favourite JAV actress, on the set they both have to wear a strange headband, and next thing he knows they’ve temporarily swapped bodies, she will make love to him, it will be a thrill of discovery for them both… And we’re not done yet, but I’m not telling ^^
The drawings were good enough, the story was refreshing and not boring, I call this a worthy read, personally!
Thanks to Espeon and Desudesu for that one!
By the same artist, I also share Yama Kami-sama Ni Negai O (“Make a Wish to the Mountain God”).

What’s the drawing error?
I’m giving you one last chance to double-check before I lay it out for you
I’m guessing the bottom panel of page 13, because both male and female legs are occupying the same space. Or one of them is Kitty Pryde.
I was thinking of the image I placed on top of this post, actually.
Oh, well, simply: the vagina isn’t at the horizontal center between the left and right thighs, here. It didn’t struck me at first, but just as I was about to publish this share, I noticed.
As for that part you mentioned, it’s got the right number of legs, no?

Porn for narcissists.
Body swapping’s all fun and games until you wake up in your own body, exhausted, and your ass feels like it’s on fire.
