The mutagens were so thick in the air that he couldn’t even think straight. He couldn’t fight his urges, and soon, he was painfully erect again. He could even make a noise or get anyones attention for help before her thick, lioness lips swallowed his dick whole. She started riding slowly, letting him feel her mutated vagina. She out her hand over his lips as she felt her mutation spread even further. Her eyes turned pink with lust, just like the panther lady earlier. Her crotch started sprouting tiny golden hairs that got longer and more visible with each thrust. Despite her size, she was surprisingly flexible and muscular as she used the bed instead of his body to guide herself. He didn’t feel an ounce of her weight on him, but he could feel the mutagens change him as well. Inside the nurse’s fat vagina he could feel his dick changing, shifting, morphing as the mutagen spread throughout his body. Then, both of their changes started to flare up.
From being inside her, Josh could tell that more than just the nurse’s vagina had changed. The reason she was so much thicker was because the mutagen was changing her insides, making her able to bear a lion cub before changing externally to look like one. Everything inside her was bigger, from her bones to her lungs, with her muscles tearing and growing and her fatty tissue getting thicker and thicker. He could tell that when she was human, she was much smaller (despite still being overweight), but now she was the perfect thing to put his newly feline seed into. His muscles tensed up as he started to break his restraints. His crotch started to itch as his pubes changed from a dark brown to a lighter brown, the texture changing from thick hair to coarse fur. Even his balls were covered in fur. His canines got sharper and longer as he licked his lips, ready to climax. She started moving faster, sensing his climax was close, and whispered into his ear, “Give it all to me, baby.” His pupils narrowed as he felt each wave of seed exit his shaft. His grip tightened on her as his hands got bigger and meatier. The both of them were now drenched in sweat, alpha feline musk permeated the room as the two of them stared at each other, waiting for the other to make a move.
