Getting A Workout In
On Saturday, the 3 guys had a lovely brunch together. Before setting out for Ethan's old gym for a workout. Mark wore Ethan's old baseball jacket and shirt. Matching it with a pair of his skimpy gym-shorts and sneakers.
Roy had grabbed Mark from behind in the hallway. Stretching the waistband of the shorts back. He saw that Mark wore a pair of his white jockstraps underneath the shorts.
"Look, man, this one is ready to play with the big boys, Ethan," he called happily to his brother.
Ethan dropped a hand down the crack and fingered the asshole.
"Fuck!... And he has prepared his ass for a workout too!" grinned Ethan back to Roy.
At the gym, the men pumped some iron and then some ass. One of Ethan's old high-school mates had recognized them as they walked inside. He was an assistant trainer at the gym. Tyrone was a big, ebony muscle god. Tall and handsome with shorts that could hardly contain his fat cock.
Tyrone had greeted Ethan and Roy like old mates. Bro-hugging them with some nasty ass-grabbing.
"Hey, boys... Long time no see!... What's up, dudes... How's it hanging?" joked Tyrone as he snugged the two jocks. Not noticing that Mark was with them.
"Hey, stud... Doing great... Still feeding that anaconda of yours boy-butt?" grinned Ethan, "This is our new stepbrother... Ty, meet Marky Mark... Could you show Marky the works?... He needs to bulk up a bit... And... Ummm... If you can stretch him out... his muscles are pretty tight."
"Oh... new boy-butt to train!... I do like that!" grinned Tyrone, dirty at Mark. He showed Mark around the gym's equipment. Sizing Mark up as they walked around. Helping Mark to warm up his muscles and showing him how to use the equipment. Mark had not spent much time in a gym. And certainly not with his own personal muscle god as a trainer.
Taming A Brown Trouser Snake
Tyrone put Mark through his paces. When Mark was doing some weightlifting, Tyrone stood behind his head to spot Mark. Mark saw the cockhead dangling out of Ty's shorts. There was a drop of precum glistening on the tip. Mark raised his head a little and kissed the dick's tip.
"Be careful, boy!... I don't want you to choke on this snake," hissed Tyrone down at Mark. His schlong instantly started to grow. Ty squatted a little lower. Letting Mark suck on the fat brown trouser snake in the middle of the gym.
Together Mark and Ty lifted the weight back onto the holder. Tyrone pushed the dick back into his shorts and guided Mark to a backroom. Ethan and Roy join the two surreptitiously as they walk past them.
In the backroom, Mark was placed on his knees in front of Tyrone. Ty dropped his shorts, and a fat 11-inch dick popped out. Nearly hitting Mark in the eye. Mark looked up at Tyrone for a bit. Then at Ethan and Roy with a questioning look on his face.
"Go on, Marky... Show Ty what we taught you about deep-throating a fat cock... His snake won't bite... It may choke you a little... but just keep it nice and wet as we showed you," instructed Roy. Ethan guided the back of Mark's head toward Ty. That was hardly necessary because Mark gobbled the brown toy up like a pro.
That morning Mark's ass got a workout. The three guys took him in turns. Filling every hole. Taking him in multiple positions. Training Mark's body to accept even the biggest of the dicks.
Tyrone was utterly surprised by the relative ease with which Mark handled his fat slong. Sure, the teen twitched and whimpered during the onslaught of the 11-inch brown dong. But that was quickly remedied by his step brothers. They held him down as Mark's butt got gaped wide open by his first black cock.
