Since this seems to come up on this series a lot, let's just get this out of the way:
Gender Bender definition on the wiki has this note

Notes: Should not be confused with body swap or crossdressing. A female becoming a futanari does not count (but may qualify for dick growth). Possession of a person of the opposing gender is acceptable.
Reup: Accidentally a word.

So basically they got caught masterbating, so decided to get someone to take her life and live as them, whom now lusts over their 'new' sister? Nice.

A different method of helping the NEETs and shut-ins have another chance at life...
Maybe a twisted way, but hey at least it produces some "results"...
Date always makes the best possession/mind control stories...

This whole series is so scary and arousing at the same time. Scarousing!

@LearnJPwithH, honestly a lot of bad tagging goes around too much. A character who doujins I do gets tagged as Lolicon when clearly the character isn't, so...

If you see flat chest, apparently it must make it Lolicon despite the clear fact of age, all because of a certain artist who makes the character look like a little prepubescent girl.

Male gender bender should really make females only tag invalid. Or add fake females only tag instead. Makes you wonder how this is even females only if the guy is present in every sex scene.

Base +18, DOKKOo +6, danielwain +9, HouraiHime -6, anon1437 -6, jedikid129 -6

I want that story about that last guy who took over a girl to continue. I wonder if the guy will fully assimilated with that chick.

Base +7, Soldier A +6, zykyne +7

People coming to sad panda to argue over tag classifications for porn. Makes you wonder what they're really here fapping to...
There's all kinds I guess /s

Base +6, badabimmbadabumm -5, hitmeup +6

These keep getting better.

Base +6, DOKKOo +6, DarkCocoon +6

It's not gay if you say no homo, c'mon that's like rule #1
