>could even just be a fuck up by the futas part
I've thought of a few scenarios
- Hyper fixation on how good her cock feels in the femboy's ass causes her to become the cock
- Magical spell or potion being used incorrectly, applied to the wrong person
- Side-effect of a dick growth spell/potion, using her cock before the effect has stopped making it spread out of control
- Femboy is cursed, he tried to avoid sex (maybe he absorbed a woman in the past which caused him to feminise) but the futa wasn't taking no for an answer
- In a different scenario, a femboy cleric who sets up a trap for a futa succubus
- Similar to the trap set-up, a party using their femboy companion as bait for a futa sorcerer

That's what I was thinking when I made it. He's now stuck because not only would he be too weak to deal with such a large cock he's still bound and has to try and lighten the load by using his legs/feet and the floor to empty his balls
