Enjoy the Ride - Part 3

I woke up on Saturday, June 3rd, with a sense of dread on my insides, a feeling that had been my constant companion for the last few weeks. Four weeks had passed since the day I started experiencing pregnancy symptoms, struggling with morning sickness and permanent fatigue. I had informed Mr. Gri...

When Two Worlds Collide - Part 1

Jivin tried his best to keep quiet, but much like everything else, doing so was difficult. As such, he couldn't help but grunt as he attempted to adjust his massive body in the back of his Uber.

Sweet Gains - Part 7

Liam and Aiden managed to reach Aiden’s car parked in a nearby alley without anyone noticing them. Aiden owned a large SUV, but their size still represented a challenge in their runaway plan. Aiden was a mountain of muscle, well over 600 pounds, with broader-than-door shoulders, tree trunk arms...

Hot Beached Whale - Preview

Arion took a deep breath as he stood beside a large beach towel that his boyfriend, Kai, had placed on the sand for him. The heat was insufferable, but the ocean’s fresh breeze made things better. Also, having the chance to be out of his constricting clothes was a bonus, even though he wasn’t...

Wrestling the Changes - Part 3

Hayden couldn’t keep his hands off his abdomen on the way to his hometown. The scene in the doctor’s office repeated in his head as he tried to process what was happening to him. His secret encounter with Marcus was also on repeat in his head. Hayden and James weren’t exclusive, but they we...

Dreaming! - 1

Donny covered his 6-inch-long dick with a new lube he ordered online and had just arrived. The lube promised to enhance the genitals' size, which sounded like a dream come true. His dick got hard while he rubbed more lube over his dick, carefully covering the whole shaft.

"Hmm... 6 inches. ...

Father's Day - Part 2

Casper couldn’t stop thinking about his family while he continued caressing around his engorged, leaky nipples. The sensation was strange but somehow made him feel better. His pecs were always extremely full, so caressing the nipples while the pressure went down at least a bit was a tiny light ...

“Ugh. Stop moving. Stop kicking. Stop growing. Daddy can’t take this anymore,” Julien groaned as he waddled into his house after work, rubbing his overpacked belly. “You’re almost 2 weeks late, and Daddy can’t grow anymore.”

Julien closed the door beh...

Enjoy the Ride - Part 2

When we arrived at Mr. Griffin’s penthouse, I was speechless. His office was enormous, but his home made me feel like I had entered Narnia through those double doors. My 2-room-and-1-bathroom apartment was nothing compared to his living room. My whole place fit in a corner of his living room. I...

Sweet Gains - Part 6

Chris parked at the address Liam gave him over the phone. The place looked quiet and normal, confusing him because Liam sounded terrified.

Give or Take - Part 8

Since Bryce didn’t know what had happened with Mason, he thought the worst. He imagined someone kidnapping Mason to use him as a science experiment, or maybe they had taken him to quarantine. Even if people didn’t know about Bryce’s power, Mason’s enormous body was far from average, so th...

Five-Star Pecs - Part 5

Steve tilted his head back and softly moaned, trying not to scare or disturb the babies suckling on his nipples. Due to the size of his belly and the outstanding size of his milky pecs, he hadn’t been able to reach his dick in a few months. He had used some creativity to get some release every ...
