Marcus Rivers Gets a Serious Ass Workout from Dolf Dietrich on FunSize Boys

You Will Never Look at Pushups the Same Again!

Dolf Dietrich is a force of fucking nature. Not only can he get you excited about some of the most boring exercises known to man, but he makes you wish to hell that you were one of the FunSize Boys. He has a penchant for them and in this ninth chapter in Marcus Rivers’ story, Dolf gets to both workout and have his way with the cute twink as part of his job as “Personal Trainer.”

The action starts on simple mats in the glorious outdoors. The duo is staying at the country cabin of Marcus’ parents for a special exercise intensive weekend. The visuals during this 17-minute scene are so pleasant, and that’s not just referring to the performers. The cabin’s surrounding greenery not only provides a modicum of privacy but also a gentle beauty to serve as a backdrop to the masculine play of Dominance and submission on the deck.

First up are sit-ups. Oh, yay. But Dolf has a new sit-up variation he’d like to try. It requires the much lighter and shorter Marcus to wrap his legs around the 6’6” coach’s waist, lean back, and sit up. It’s not easy, as Marcus quickly learns. But he’s able to make his trainer happy with how many crunches he accomplishes. Dolf doesn’t mind the fact the two men have had their genitals jammed against each another, either.

It’s a great core workout, so the two strip off their shirts, and the “Personal Trainer” runs his hands admiringly over the results of his instruction and encouragement. Dolf observes that Marcus’ six-pack is becoming an eight-pack. This isn’t their first rodeo, so they get down to business promptly by kissing and groping one another. Then Dolf brings his cock out and things begin to get serious, with Marcus kneeling obediently to suck the handsome and heavily tattooed man. It’s a particularly hot moment, with Dolf’s dark shorts and underwear pulled down but not off while his King Size erection gets the attention it deserves.

The former basketball player turned one-on-one coach is naked except for his tall sport socks and he has another innovative exercise for Marcus to try. Dolf lays down on the mat and has Marcus move into a 69 and then do pushups. This is not an easy feat for a number of reasons, primarily among them the fact the Dolf has a thick fuckin’ cock. Just getting that thing in your mouth is a challenge, but to do pushups while making space in the back of your throat for it? Amazing. And so hot. The worse Marcus’ pushups are, the better the cocksucking is.

There’s only so much time two men can spend with their mouths wrapped around each other’s dicks. That time ends and yet another pushup variant is introduced. This time, Marcus does traditional pushups, but with Dolf’s cock in his ass, so every push-up is a push deeper into his asshole. This hasn’t escaped Marcus’ notice and he squeals and whimpers like a wounded but really turned-on animal. “So big,” Marcus gasps out at one point. Fortunately for me, he also moans and sighs, so I know he’s digging that hot tube of man meat thrusting in and out of his ass.

During a moment of rest, so that Marcus can collect himself, the world is temporarily serene, with only the sound of birds calling to one another. When the action gets back in swing, Dolf checks in with his long-suffering bottom to make sure he’s having a good time. “Is it good,” the heavily tattooed Top asks. “Yes,” Marcus gasps. This is good because there’s way more fucking to be done. Soon the young twink crawls onto Dolf and braces his shoe-clad feet on his thighs, controlling the thrusts, their speed, and their depth. “Oh, that feels good,” sighs Dolf. “Oh, this is great.”

What’s great is Dolf’s orgasm. It’s inside of Marcus’ asshole, so we can’t see the actual eruption of cum, but we can be amazed by the tension released as his body lifts, stiffens, and is entirely overwhelmed by sensation. Marcus rises with Dolf’s hips and is clearly feeling a lot of pressure, what with a huge cock pumping hot jizz deep inside of him. The camera shares beautiful visions of this FunSize Boy’s courageous asshole filled up with turgid flesh, with cum spattered all over the place.
