A lora that creates a obscure japanese fetish monster known as a Futanari Bridge Monster or futanariburijjikaijinn, as describe on the fetish is basically this taken from e621.
"The idea is that a person masturbates so much they becomes a penis person, walking on all fours while the penis takes over as the main body and wears their clothes."
Best used with prompts such as "all fours" and "arched back", experimental prompts include testicle_tattoo, mind control, precum burst, multiple views, and pink/red aura,
Here is a start up prompt: /futanari_bridge_mutant, arched back, all fours, huge penis, large testicles, breasts, erection, uncensored
Side note: if you leave out all fours and use walking or standing you can get literal walking penises.
