When her mom's smell hit her she got horny and felt the need to mate and spread the virus. She cast a illusion on herself to make her look like her old self and another to stop all sound from leaving the house. She headed down the stairs. As she was headed to her mom her mind was still being changed and when she found her in the kitchen her old self was gone and the new one wants to infect the world and have Kitsunes rule it. She give herself a new name, Krystal. Krystal grabbed her mom and cast a illusion on her which knocked her out.
She took her mom to her room and undresses her leaving her naked. Krystal removed the illusion on herself showing her new form. She looked at her mother who has mid c-cup breasts, long red hair and was pretty for a human but she knew when she's done mating her she will become a Kitsune. She woke her mom up. "What? Were I'm I?" She said till she saw Krystal. "Jason?" She asked her. "It's Krystal now she told her before she pulled her mom's legs apart and lined up her new cock which is 10 inches long and 2 inches thick with her mom's pussy.
"No! Please don't it's-AH!" Her mom tried to beg her not to but was cut off when her daughter's cock was thrusted into her. Krystal waited a minute to get used to her mom's tight pussy which meant she had not mated with anyone after her father died. She then started to thrust into her mom making her moan to her shame. She tried to call for help. "It's no use. I cast a illusion that blocks sound from the inside so no one will hear you call for help." Krystal told her with a grin enjoying the sex. Krystal started thrusting in faster and harder into her mom. While she was fucking her mom Krystal's pre-cum was changing her mother in both mind and body. Fur was starting to appear on random spot on her mom and her breasts started to grow larger with another two sets appear below her first pair and till she had three sets of high dd-cup breasts. Krystal flipped her mom on her arms and legs and kept thrusting into her mate going deeper as she was starting to lose control of herself. Three tails started growing on her mate's tail bone and her face was changing into a fox's. She grabbed her mate's new tails and used them as a handle as she dominated her mate. Krystal was soon fucking her mate wildly without control and was hitting the entrance of her mate's womb. "AH! YES! MATE ME! BREED ME WITH YOUR SEED!" Her mate Isis cried out wanting more and was willingly pushing back to her mate's thrusts. Suddenly Krystal give one last hard thrust into her mate entering her womb and cum in it impregnating her. "AAAHHHH!" Isis cried out from the feeling as she cummed from it. She blacked out from the pleasure after that. Krystal collapsed on the bed. She was thankful that it was a weekend and fell asleep beside her mate.
