Can you even imagine how odd it would be if your best friend turned into a girl, you both end up doing the deed and he turns back into a dude afterwards. Probably would be really awkward afterwards.

Another gender bender, another great day

This is pretty good gender-bender content on Unlimited, imo. The guy-turned-girl is sexy, the guys... look okay, the art is good, and the guy-turned-girl really starts getting into it, a major plus in my book.
And reading the original series is not at all necessary to understand and enjoy this one. In fact I'd go so far to say it adds virtually nothing, so that's nice. You get the general gist of it in Panel 3 on Page 2 anyway.
My only real complaint is that it feels a little too short at 12 pages. A sequel isn't really needed, but it would be nice to see and is even kinda hinted at. Hopefully more gender shenanigans would be in store.
Honestly FAKKU could use more stuff like this; there are other genderbending stories on FAKKU Unlimited, but there could be so much more to incentivize those who want this kind of content to sign up.

Why can't this happen to me, but permanently

She can't make them fuck her right? No controlling people's minds

Wow guess Kirby fell on hard times, Nintendo royalties must be drying up.

A bit weird.

If my friends turned me into a girl they would get a sound beating. And then it would be yuri fun time with the Goddess of Sequels...

Hmm, a side story to this series? Interesting.
Didn't actually have anything to do with the teacher, but it was still rather interesting.
"It's one of those things that take your soul as payment!"? Well...They certainly understand how these kind of things work.
"Why didn't you just summon an actual girl" ? Well...Because hentai, and it's probably more interesting this way.
Great ending though. I half expected him(her?) to change them into girls too, but all he(she) wanted was more sex?

"IT'S PAYBACK TIME!" Do Not Hold Back, Rio-kun ... It Is Your Destiny!
