It had been pretty rough for my dad recently. My mom left him a month ago and he just lost his job. I was worried for him and his well being. However, that all changed on one fateful day.
I had just come home from college for the summer break, and I greeted my dad like usual, talking about my finals. But the entire time he seemed distracted, constantly looking at his phone. I just assumed he was just on some dating app and was talking to some girl, so I let it be. The rest of that day, I never saw him, but I heard some weird noises coming from his bedroom. At one point I knocked on the door to check if he was ok and he said he was fine. Deciding not to push it further I just went asleep, blissfully unaware that my life was about to change.
I woke up and went down stairs to eat breakfast. While I was eating, my dad walked in, but he was clearly different. He was only wearing a jock strap so I could see all the changes to his body. He was now very tall, dwarfing my already impressive 6'5" frame, having to be at least 7'2". Was also significantly hotter, having a super attractive face and beard where he couldn't grow one before. The most noticeable change was his body. He used to be kinda scrawny, and started to put on a few pounds, but now he was absolutely shredded, bigger than any guy I've seen at the gym. Then finally there was his bulge. Although I've never seen his cock before, I have seen him in underwear and knew that he was nothing spectacular in the cock department. But now, it looked like he was packing at least 8" of soft meat in his jock, plus some huge balls.
Shocked by his transformation, I stammered "D-dad, what happened to you?!"
He just laughed, the air seemingly shaking from his new ultra-deep voice "Just a little upgrade boy" he replied cockily
He pulled out his phone "I just found a nifty little app that lets me change people, including myself, however I please"
I started to get worried thinking about what he would do with that kind of power "What did you change?"
"Haha, glad you asked boy, I decided to give myself a high paying job, and this fantastic body. The only thing I didn't consider was how much of a problem this would be" he said as he grabbed his huge bulge, shaking it. "The thing has got me constantly horny, I jacked off at least 10 times last night."
I was shocked at how casual he was about this "Y-you should probably fix that then, how will you?"
"You see, I'm definitely not making it any smaller, so my first thought was to find a bitch to milk it, but then realized that it was a waste of time when I already had one"
Now getting really worried I asked "What do you mean?"
"I mean you son, I know you're gay, so I thought that it would make a nice gift to make you the servant to my new god body, speaking of which, I had pre-set some changes for you" He said as he pushed a button on his phone.
At that moment, I started to feel weird. I felt my muscles inflating, especially my ass, which grew to huge proportions. After a while I felt a strange feeling in my ass. It almost felt as though it needed to be filled, like it was hungry for cock. The same feeling happened in my throat. And then finally, I started to crave cum, almost as if I needed it like water. I looked up at my dad "What did you do to me?!"
"Oh nothing really, just physically changed you to be able to take my new cock, and made it so that your body constantly craves cock and cum, like any good muscle slut should." He replied casually, walking towards me.
At this point my cloths had ripped of my body, my growing muscles overpowering them. I decided that I needed to escape, so I tried to run, but I tripped ober my self and landed ass up.
My dad started to laugh "Even your body knows what it's made for, it wont let you escape, after all you're just my toy now" He pressed one last button on his phone and put it away. "Now come over here and suck me off boy" My body automatically responded, going to him, dropping to my knees and taking out his now hard 14' cock and sucking it like my life depended on it.
From that point on, my life was completely controlled by my daddy. After a while, I started to love it, I loved being his slave, serving him, swallowing his cum. And that's how I find my self here, on daddy's bed sucking off his morning wood as he wakes up to start his day.
