Due to having Varicia penetrate her, the kids would most likely be Varicia's but who knows, perhaps mutation could make her grow another womb, or simply reroute it to her penis. As it was, the two women, tired from the furious tidalwave of cum they unleashed inside of Emily. They fell asleep around her, Varicia resting on her gigantic set of balls while Nelia nuzzled her face into Emily's as they drifted to sleep.
Unbeknownst to them, Emily's infection starting changing them in their sleep, sending their mutations into overdrive. Varicia would have left at the time Emily awoke, scared, embarassed, or just spurned on to continue her work. Nelia though stayed, cuddling into Emily with a loving embrace as she slowly changed. Her eyes changed a sparkling, almost digital looking sky blue that seemed to simply entrance anyway looking into them through their sheer beauty. Her cock shifted between her legs, slowly growing outward. When flaccid, it would be just as big as before, but when erect it would grow to a startling 15 feet length with a 5 foot girth that looked like it could split anyone in half. Her pucker and pussy tighten, like they could squeeze the life out of anything inserted into them. She hugged Emily tighter as the changes occured, seeking refuge in her warmth. Her breasts slowly grew outward, starting to envelop Emily in an even softer embrace as the slowly grew to ridicolous measures, medicine-balls ready to envelop you in a fleshy soft prison. Her hips grew curvier, ridiculously firm buttcheeks decorating her rear that grew outward until she had enough to balance a bottle on it. It was incredibly firm though, soft to the touch but not jiggly. Her flawless skin made it look perfect, a volutuous vixen ready to give the night of your life, if you survived her erection. In fact, she could probably develop a new style of infiltration now. Tempt important people into a more private setting before crushing them with her cock. A sheath appearing above her pussy to hide her burgeoning manmeat underlined this strategy, making her able to hide her massive mammoth of a cock whenever she wanted as well as release it. Other than her ears growing a bit pointier and her face a little more aluring, these remained her only changes as she rested next to Emily.
