Jeff woke up the next morning to the sound of sizzling bacon and eggs, the delicious scent wafting upstairs. Only half awake, he followed it to the kitchen, where he was faced by the huge brick wall of his dad's enormous back. He sighed in relief. Mike hadn't made any changes, it looked like. "Hey Dad, whatcha cooking? Smells fantastic," he said, getting himself a glass of orange juice.
"Oh, Jeff, you're awake!" Mike turned, and Jeff nearly choked. In his left hand was a woman, who he slammed up and down onto his cock with ease, while casually serving breakfast with the other hand. Each time he speared her, Jeff could see the outline of his dad's cock deep in her, even pushing out her breasts with its enormous length. He was sure it wasn't that big last night. Mike saw the look on his face and smiled. "Oh, I did make a little enhancement while you were asleep. Don't worry, it was only one, and I only did it this morning, at her request. You should see the way she begged for this cock."
Jeff spluttered, eyes wide. "Who is she?"
"What, you don't recognise your own mother?" Jeff gaped. There was no way that was his mother. She had blonde hair, and huge, pink lips, and her breasts were as big as Jeff's head, none of which she had the day before. "Madeline's trip ended early. She came home after you went to bed, and when she saw this new body, she went crazy."
"What did you do to her?"
"Oh, just made a few improvements to her. Bigger tits, less brain, a pussy like you wouldn't believe. Also, she's completely subservient to me, now. Does anything I say, even if it seems impossible. Isn't that right, Maddi?" Maddi's lips opened as if she was about to moan her agreement, but no sound came out. Mike smirked. "I told her to stay quiet while you slept. Now she can't speak at all."
"God, Dad, that's-"
"Amazing, I know!" With a grunt, he orgasmed and unloaded into her waiting pussy. It seemed so casual, and he tossed the rotund woman onto the floor, discarding his slave to properly greet his son. Jeff took a step back as Mike rounded the counter, and took his first good look at his dad's tools. Across two beanbag-sized balls, draped not one, but two thick cocks, bloated with vascular muscle. They hung a full three feet down soft, each as wide as Jeff's thigh. The giant flexed them, and they sprung to attention, towering over Jeff's head and wrapping around him like great pythons, dragging him closer to the 10-foot beast that was his father. "So, now you're awake, what's next?"
Jeff jolted. "What?"
"What's next? I'm thinking maybe some more animal changes or some more sexual enhancements. Wouldn't mind growing a bit more too. What do you think?"
"You want me to use the Chronivac on you again?" Jeff asked. Mike's head tilted downwards, eyes narrowing as he regarded his son. "You can't be serious. I mean, look at you!"
"You don't want to transform me more?" Mike said, deceptively calmly. "That's a shame."
Suddenly a hand came down on Jeff's shoulder and threw him across the room. He landed roughly on the couch, and watched as Mike turned to Maddi. "Restrain him," he told her. "Don't let him move an inch."
Maddi nodded and quickly lept onto Jeff, straddling him. Her weight bore down on him, and he found she was far stronger than she looked, able to completely freeze him in place. "Sorry, Jeff," Mike called. "But you don't understand. I need to transform. It feels so fucking good, and I will not let you take that away from me. Instead, you're going to watch it happen, and there's nothing you can do about it."
Mike picked up the Chronivac and typed something in.
