Then one summer came when everything changed…

Logan’s mom was having a hard time being a single mom. Especially after Logan got into some fights, she needed a break and for Mr. Stone to start playing a more active role. After all, the two hadn’t spent more than a few consecutive days together since Logan was in middle school.

They’d become somewhat estranged, but of course Mr. Stone was happy to take in his son. The first day was a bit weird. Logan had yet to visit his old man’s new house in the country. It was bigger and more open than he was used to. He didn’t really know what to do to fill his time, but Mr. Stone made sure that Logan couldn’t get into trouble.

Before the young man had even fully unpacked, Mr. Stone explained that there would be strict rules while he was there. And that he was expected to do his chores and help out around the house.

Logan wasn’t expecting to be on vacation, necessarily, but he was surprised by his dad’s tone. It wasn’t the familiar, soft voice he remembered. Mr. Stone was talking to him like a man, like an adult.

For Mr. Stone, this was understandable. His natural increase in muscle mass was one of the first things Mr. Stone noticed. Somewhere over the last few years, Logan had sprung up about 6 inches and added a significant amount of mass to his body. Mr. Stone even thought he saw a five o’clock shadow beginning to emerge.

It caught him off guard, and also filled him with a sense of pride that his boy was becoming a man. Despite having missed out on some quality time with him as a boy, Mr. Stone felt more comfortable approaching him as a man.

The day was coming to a close and Mr. Stone told Logan to mow the lawn. Logan did so, happy to get some time alone and to think. Mr. Stone watched from the window. First to make sure that he was doing it correctly and not going over any of his plants. But as he continued to study him, Mr. Stone became more fascinated by the new man he saw…

When Logan came back in, he was exhausted and sweaty, needing a break from the intense summer heat. There was hardly a breeze and the lawn was massive. Mr. Stone looked up from his book, seeing the dripping young man before him, and happily offered him a seat next to him in the air conditioned room.

He could tell Logan was working hard, so he instinctively leaned over to massage the deltoids of his son and asked—playfully, he thought—when Logan put on so much muscle. For Mr. Stone, it happened overnight, but for Logan, it was hard to say exactly when this change had occurred. His arms were thickening into those of a man's, but his round eyes and clean expression still carried with it the innocence of youth.

Logan shrugged, embarrassed. It was very paternal and sweet for him to say it, but he still felt like a stranger around him. Mr. Stone sensed his son's embarrassment, paused, and turned his eyes back to his novel. He figured the young man didn’t want that kind of attention. He remembered how he was at that age. But before he got a line into his book, his concern was replaced with intrigue.

"Don't stop," Logan pleaded under his breath. It was the first time anyone had touched him like that… and he didn’t want it to end.

Suddenly, Mr. Stone thought an awful lot about Logan's embarrassment.

He was arrested by the sight of the trembling boy. Mr. Stone's carved, experienced hands slowly extended back to his son's firm shoulders. He kneaded sweat-stained skin, rubbed the nape of an overworked neck. Every new bit of pressure he rubbed into Logan's traps, he saw equal parts of pleasure and uncertainty mixed on the boy's face. Both man and boy had, unknowingly, instinctively, spread their legs just a bit wider than before.

And his were not the only hands that wandered.

Mr. Stone felt like he was viewing himself from the outside, witnessing something he wasn’t supposed to see—the discovery of what made Logan aroused. And it wasn't just discovery, it was participation—it was his hands, his masculinity, his touch that melted that boy so.

Mr. Stone wanted to look away, to turn his head and hide his face. He knew if he had any sense at all that he would stop and walk away and pretend like nothing was happening, that he was just a guy supporting his son who had earned a break. Nothing more. But as he felt a familiar stirring in his loins, inspired by the feel of his boy’s matured muscles relaxing under his touch, he knew it was something… something much more.

He didn’t retreat, though. As much as he had doubts, he also had the desire to be there. For his boy, who clearly, from the grip of his delicate hands on his father's thick thighs felt the same way…

And so, after painful study and scrutiny, Mr. Stone gave Logan what he needed and wanted. He gave him the taste of another man's mouth and demonstrated how tongues should twine around each other. He gave him the powerful grip of another man on his neck, chest, and groin. He even showed him how to suck dick—a skill that, he himself, had forgotten he had, the years of his last experimentation long behind him.

Like landmarks on a map, Mr. Stone showed his son the most important pleasure points in a man's body. He spread the boy's legs wide and tested the boundaries of Logan's hole. The big man rubbed his boy’s taint, found the tiny hole, and drove his digit down into the entrance all the way to his knuckle. And with every test, Logan passed with moans of pleasure, and opened himself up to more lessons.

But all of that was orchestration. What really turned Logan on was the sight of his father's cock. It was big, and hard, and covered with the aura of experience. He loved watching it twitch and move, and he practically forced himself upon Mr. Stone, eager to show the old man that he had been paying attention.

Every detail of the pleasurable lesson that Mr. Stone showed the lad was paid back in kind with his hungry mouth. It brought Mr. Stone to white-knuckle eruption, and the hint of tears.

So drowned in pleasure, confusion, and lust at the sight of his son's cum-soaked face, Mr. Stone couldn't help but instruct one more lesson. He held Logan in his arms as the boy stroked himself off to completion. He guided him through an orgasm he was sure he'd never forget…
