Blobfather Indeed!

You nod, "Yup. Just like that. Happens instantly like that one just did."

You watch as he holds the cup and swirls it around a bit in his hand. One hand rubs the side of his belly as he does so and he's in deep thought, looking down into the cup more. Letting him think, you go back to the chair and take a seat, waiting for him. Now your heart is really pounding in your chest. This is it. The moment of truth. You shouldn't be so excited though, right? This isn't normal! But having wishing powder period isn't normal and you have that in spades now. You bite your lip as you think about what's going on and feel that familiar stir in your own shorts. Then, dad takes a sip.

"I wish," he starts. "I wish I was 700 pounds. That I was and remained fully mobile and healthy. That I actually got healthier the bigger I got. I wish that I could gain weight easily and could never, ever lose weight. And... and that I had the energy and vitality I had 20 years ago!"

That was certainly a shock. You weren't expecting all of that but your wish earlier did make it so that he'd vocalize his desires. Honestly, you had no idea that these even were his desires. There was so much packed into that wish that dad had to have been thinking about it for a long time now. Maybe longer than you have at this point. When you look at him, you see a big smile on his face and watch as his body starts to expand.

You don't feel the lurch of the magic yourself, at least not as much, since this one was all dad. Instead, you see his body expand and swell like rising bread dough on a time lapse video. His belly widens, softens, and expands bigger in front of him, rolling his shirt up to his chest before it starts to split down the seams with a loud tearing scream. The shirt falls away as the neck snaps from his chin and neck getting thicker and you're left looking at a huge, fat, hairy belly with two enormous hair covered moobs rolling down the sides of it. His shorts follow suit with them splitting open at every seam until they lay on either side of him on the couch. His thighs have grown so big that he has to shift to get them spread apart and his gut bounces down between them as it grows. You can't look away as he spreads out wider across the cushion he's on, now rolling over to cover two of them on the couch. His calves and feet widen and fatten as well, keeping up with the rest of him. Plus, you can easily tell that his body is making sure to be mobile by seeing that his lardy arms and legs are also morphing with clearly built up muscle under them.

There's another tear and your dad laughs, his big gut bouncing as it rolls to his knees. That had to have been his underwear since there was no way they would be able to stretch that much. Dad just rubs the side of his hairy belly with one hand and holds up the cup of liquid in the other, smiling. By the time his body settles, it's wobbling, glistening with sweat, and making the couch creak under him. His fat cheeks dimple as he smiles bigger than you've seen him smile in a long, long time.

"Son... It... This is amazing," he says as he grabs hold of the arm of the couch and starts to roll himself forward.

The couch creaks and you watch his blubber wobble as he scoots forward and leans to get himself up off the couch. A deep, bearish grunt escapes him as he pushes upward and stands before you, a couple inches taller to handle the mass, and his whole body ripples and shakes. He's massive. And he's still holding onto the cup. You stand up in front of his gut, feeling the heat radiating off of him and getting a whiff of his now much richer musk. It smells good, honestly. Powerful.

Then...
