Magical Girl vs. Petrified Lust Trap!
Once a land god, now a magical girl!
Okitsune Magical Girl Silozette runs to protect the peace of the city!

Monsters from the park playground have appeared to break the peace.
And what was carved into her womb was a lewd mark that ――petrified with pleasure!
To release it, you have to insert a very thick pole...!?

Silosette is at the mercy of the first wave of sexual sensations she experiences.
The body was about to undergo irreversible transformation ――…

...seems even the existences called "gods" can be distorted and shaped by strong human desires.

Also: loved how all the twisted wishes gave her multiple tits and nipples. Hopefully she can keep nourishing the people of the city with her foxy titties for a long, long while...

Old god turned magical girl being petrified via a stamp rally is certainly not a combination of ideas I could've conceived.
