“Looking good, Nate!” I told my grandson, once he was done with his night jog.
“Grandpa, my name’s Nathaniel,” he answered with a sigh.
“C’mon, champ, that’s an old name name, and you’re no old man, right?” I patted his back. “And these tattoos give you some edge, looking like a tough guy!”
“I’ll take a nap upstairs.” Nathaniel walked forward, but I stopped him.
“Hold on, cowboy.” I nodded toward the kitchen. “Go drink your Grandpa’s special juice, you still have some lifting to do.”
I looked at Nathaniel in the eyes. “C’mon champ, all this training has made you bigger, let’s not give up. You want to make your dad proud, right?”
Nathaniel stared at me and frowned. “Fine…”
He headed toward the kitchen while I scratched the back of my head.
“Jeez, the kid has no backbone,” I muttered to myself.
While Nathaniel was busy, I walked upstairs to my room. Once there, I used my necklace key to open a drawer which had a book inside. One of the pages had pictures similar to the tattoos I got for my grandson. I flipped through until I arrived at the chapter which had the same symbols I had tattooed on my arms.
“Sorry son, but your kid needs more than a man-up holiday.”
I lit some candles around the book and read outloud its Latin writing.
“Im ‘agnus dei mei equi accipere. Im ‘agnus dei ride, usque non possum ultra!”
The flames snuffed on their own while the smoke levitated around me. It envelopped clothes and devoured them. Soon, my whole being was being engulfed and became one with the mist. I smiled and flew toward the gym room. My grandson was there, being a good boy as always and doing what he was told to do. I watched as he lifted the barbells and chuckled, knowing it would soon be my turn.
“Huh, what happened?” Nathaniel wondered, hearing me. He looked around and saw me. “What’s that thing?!”
“Howdy, champ,” I said through my spectral mouth.”
“It doesn’t matter. What does matter is what I’m gonna with you, kiddo.”
I lunged toward my grandson and surrounded him.
“Grandpa, what are you doing?!” Nathaniel yelled.
I charged toward my grandson’s open mouth as his eyes glared with shock. He choked and gulped while I forced him to swallow me up.
“HHRRRRK!” gagged Nathaniel.
My smoky tail slipped through and my grandson thrashed around.
“UNNNGGGG!” Nathaniel gripped at his head. “G-GET OUT!”
He was finally fighting for once. Sadly, it was too late for last chances.
My grandson fell down and lost consciousness. My cue. I expended my essence through Nathaniel and fitted his body like a hand puppet. I wheezed as I opened my new eyes.
My heartbeat quickened when I heard my boyish voice. I smiled and looked at my hands. They were big, strong, and strangely enough, my tattoos had replaced Nathaniel’s. I giggled and patted my face, it was soft and with no wrinkle at all. Soon, I moved to my arms.
“Damn, look at these guns!”
I flexed my biceps and felt them. Excited, I leapt off the ground with ease thanks to my athletic legs. Then, I stepped toward a wall mirror and admired my reflection.
“Hey hot stuff, you’re single?” I joked. “Hey sir, welcome to the zoo, wanna some pythons?” I flexed my biceps and laughed.
Suddenly, my phone vibrated. It was Nathaniel’s… Well my dad now I guess. An idea flashed in my head and I took a selfie for my new father.
Just as expected, my old man called me right after.
“Wow, son! Your grandpa did an amazing job with you,” my dad praised.
“You have no idea.” I chuckled to myself.
“By the way, can I talk to him?” he asked.
“Oh, he’s gone fishing,” I replied.
My father rose an eyebrow. “Really? At this hour?”
“Oh you know grandpa, always the daredevil.”
“You’re right. Well, keep on working these muscles son! All the ladies will fight for you!”
We said goodbyes and hung up. I fell on my back and laughed.
“Haha! If only you knew dad…”
I caressed my pecs through the tank top and smirked.
“Sorry Nathaniel, but you were wasting your youth. Studying all day when you had a gorgeous face. After I’ve bulked up your body, I thought you would come around, but I guess it was meant to happen…”
My left hand slid on my crotch and I groped it.
“Ooooohhh… And you’ve never jack off before? Such a waste…”
I crept my fingers under my shorts and stroked it.
I lifted my top and fondled my abs.
I bit my lower lip as the stroke got harder and faster. I put up my right arm and bent it behind my head to rest it. Then, I licked my veiny bicep while sweats dripped on it.
“I’m a fucking sex machine!”
My dick grew larger while my strokes grew in intensity.
I panted, closed my eyes, and arched my back. My slightly hairy legs rubbed together as precum leaked.
Rockets of cum shot all over my sturdy abs while I gasped for air.
“Ha… Ha… No more books, only sex.”
When I came back home, my father was saddened to learn that “Grandpa” had gone missing in the sea. He was of course happy to see that his son had became a real man, but his problems were not helped by his annoying boss who kept harassing him. One night, I found him wallowing on his bed.
“Hey, dad, you okay?” I asked.
“Yeah… It’s just work, you know,” he answered.
“You know, perhaps I could help.” I showed my phone. “Look, I found your boss on Grindr.”
My dad smiled. “Funny, but I won’t flirt with him. I’m not gay.”
I smirked. “Well I could.”
My father’s eyes widdened. “Huh? But-”
“Don’t worry dad, I’m not gay. I just don’t care if it’s a guy or a girl,” I reassured him.
“Oh ok. I don’t care if you’re gay anyway, I’m just… surprised.”
“I understand, a hot virile man like me liking other guys? Kinda surprising.”
My father laughed. “Don’t get cocky, son.”
“Why not? I got the body to be cocky with.” I flexed my arms.
“Son, sometimes I feel like grandpa’s spirit lives through you.”
I winked. “Perhaps his ghost even possessed me.”
We chatted a bit before I went to my room and sent some pics to my dad’s boss.
Just as expected, the man answered soon after with dick picks.
“Well Nate, time to get that hole of yours stretched.”
