Crazy futanari scientist Serena Siren brought her new, submissive test subject, Leana Lovings, to the lab. Her hypothesis was bold: continuous sexual stimulation combined with futanari sperm could trigger spontaneous genital growth and transform Leana into a full-fledged futanari. Serena sat the girl on the seat of the sex machine and pulled down her panties, allowing the thick dildo to penetrate deeply into her tight vagina. The machine started up, increasing the vibrations. Leana moaned loudly; her pussy grew wetter and wetter, and her nipples swelled and began to secrete milk. Unable to hold back any longer, Serena pulled out her big, hard cock and made Leana take it into her mouth. The girl sucked greedily until Serena came deep down her throat. Leana swallowed the thick, hot cum, and almost immediately, a new, large futanari cock began to grow between her legs. Serena was thrilled - the experiment had succeeded! Now two beautiful futanari beauties were passionately caressing each other. Leana happily jerked off her brand-new cock, bringing it to full hardness, and then they had hot sex: deep penetration, mutual blowjobs, and powerful orgasms, generously exchanging cum. Science had triumphed. Soon, the crazy futanari scientist came inside the test subject’s pussy, and she instantly became pregnant, her belly swelling dramatically. This was already the second stage of the experiment. ]]> Wed 29 Jul 2026 14:14:38 +0200 https://unusualpornx.com/video/1688/futa-world-crazy-futa-scientist-turned-a-scared-girl-into-a-futanari/
