As Kyle is double penetrating her, he feels his cock tentacle getting slowly pushed out of her slit, the transformation is beginning. Jennifer is in so much pain that she doesn't even notice her genitals morphing. Her hole finally seals up as her clit begins to grow and her labia begin to swell, and Kyle moans as her asshole begins to pucker up and inflate. Looking down at his cock, he notices her asshole is taking on an equine shape, "Looks like you have a nice donut developing back here, God I love horse ass." She cries out as her genitals rapidly finish morphing to reveal a horse cock as long as her -or should I say his- torso. His voice deepens, his tits swell and multiply, now having 3 rows of DD's with long udder-like nipples. Jennifer -now John- looks down in horror, "Look at me! You've fucked me into a freak!" Kyle chuckles, "I don't think you're done yet love." Kyle pushes one final thrust as he fills John with his seed, putting John back down. John contines to sob on the ground as his limbs morph into horse cocks, immobilizing him. Kyle leans down and kisses him, John's lips begin to tingle.
