"You two have fun, I have things to do." Ty said with a smirk. As if unable to resist Dustin and Stacey went upstairs and began to fuck. By the time they had started Ty was already out the door. Grinning to himself he realized that he had the powers of a god. "I'm not quite done with you Mark." As Ty spoke his body became larger and larger, muscle piled upon his formerly small body. He started to breathe heavier and heavier. Fur burst from all of Ty's pores as the change neared completion.
June was speeding, still unable to cope with her husbands sudden Ken-doll state. That probably would explain why she didn't notice the massive beast in front of her car. The small toyota smashed directly into a massive white tiger. June was thrown from the car with Mark close behind, somehow they both fell to the pavement unscathed. June looked at the tiger terrified "Go away you awful cat!" She screamed, to her surprise the tiger answered back. "Now you both will pay for what you did to me." As soon as June heard Ty's voice she began screaming, she looked frantically at Mark, who was slowly growing back to his former size. "Oh please Ty!" He begged, "Don't hurt us!"
Ty looked amused at his "father's" request. "No, I won't hurt you, I promise." At those words both Mark's arms became heavy, he looked and saw that they were slowly becoming the colour of stone. "No! Please!" His words were cut short by the slow spread of rock through his body and soon he was just a statue caught in a silent scream. June screamed and tried to run, but as she stood a great fire in her belly made her slump to the ground. "uugghh.. stop please.." she mumbled. Ty just laughed. Quickly the fire spread in her body and she felt her hip bones spread apart and her pussy move lower and become larger. Her clothes started to tear as she became larger. White fur sprouted from her thighs around her pussy and slowly spread around her body. Her fingernails and fingers cracked and bent until they had become the basic form of paws. Her face began to stretch and contort, sprouting fur like the rest of her body. As she was changing her pussy started dripping. Her mind became inflamed with the thought of sex. "What are you doing to meaaargh?" Her voice became a roar and her neck snapped into place and she was fully a white tigress now. "You are much more attractive now." Ty said, "But you could use something more.." Mark's statue slowly slid towards the tiger June, before she could react his body slid into hers. She felt her insides rearranging and her pussy flared out. Slowly a bulb appeard at her neck as her head started to shift slowly to one side. She felt another pussy near hers and was confused. She realized that she was becoming one with a now female Mark. The bulb on her shoulder slowly became another Tigress's head and the second cunt was finished forming. June only had basic motor function at this point because she was now filled with the lust and desire of a second animal. Ty slowly climbed up to the rump of the two-headed two-pussied tigress and shove two cocks into her waiting holes. Slowly pumping in and out causing some pre-cum to spill to the ground. Mark and June's minds were fused together but all they could think about was the huge cock inside thier slit. They rowled and started to thrust as well thier orgasms slowly building. Ty rode them for hours. Eventually they spurted out all over the street and Ty came a bucketload into thier twats. Dripping with cum they fell to the ground. Ty transformed back into a human. "Too bad you two will be stuck like that forever, maybe someone will find you and let you get fucked by plenty of male tigers for a science experiment." With this he turned and....
