Futination

An eccentric futa inventor, Serene Siren, escorts her obedient experimental partner, Leana Lovings, into a high-tech research chamber. Serene's theory suggests that relentless erotic arousal, blended with the perfect dose of her futa semen, could spark an instant physical mutation, essentially turning Leana into a full-fledged futa being. Serene secures Leana onto the mount of a pleasure device, shifting her underwear to allow the prosthetic phallus to penetrate deeply.

As the device's pulses escalate, Leana's dripping cunt becomes soaked with desire, and her erect nipples begin to leak milk profusely! Overwhelmed with lust, Serene's throbbing shaft stiffens, prompting her to command Leana to suck it eagerly. Serene unleashes a torrent of hot cum down Leana's throat, and once Leana gulps it down, she miraculously develops her own pulsing erection! Thrilled by the success, Serene watches as Leana caresses her fresh manhood until it's rock-hard and ready. The two aroused futa vixens then indulge in wild, passionate intercourse to mark Leana's exhilarating change.

Witness the wonders of experimentation!.
