Sensei John sees the young teen just outside the bathroom stall and nearly gasps. Had Grayson heard him jacking himself off?
Grayson nods to the older man as a sign of respect. "Sir, I'd like to know if you'd like to come to the gym in town with me tomorrow."
Sensei was considering this carefully. He was slightly bigger, muscle-wise, than the boy, but he'd earned it through hard work, never a gym.
Still, Sensei couldn't refuse the offer. "Alright, I'll go there tomorrow." Sensei had to shake off these feelings for the stronger man before him. He had to try and outlift Grayson tomorrow.
"Thank you sir." Grayson says, bowing. Sensei realizes if he threw a kick at Grayson right now, while he was defenseless, he'd end up getting crushed again by the other man. Sensei grabs his things and leaves Grayson, who is collecting his stuff. Sensei Mike eyes him oddly as he walks out, but John pays no heed as he gets in his van and drives home.
At home, Sensei relaxes in a chair. His wife, a beautiful woman of 40, greets him, along with his young 17 year old son, Luke. He sizes up Luke for a moment: Luke doesn't seem anywhere near as strong as Grayson. Sensei soon retires to go to sleep with his lovely wife.
The next day...
Sensei is now heading to the gym on the other side of town. When he arrives, he notices him and Grayson are some of the only ones there.
"I like to get here early." Grayson says, currently lifting some 30 pound weights in both hands. "Hello there sir." Grayson is currently wearing a black muscle shirt, showing off his fine physique, and blue gym shorts.
John speaks, "Hello there Grayson.". He goes and quickly gets changed, noticing Grayson's bag there. He gets rock hard almost instantly, grabbing the briefs and sniffing them before putting them back and heading out. Sensei is wearing a green muscle shirt, with red sweatshorts.
He goes and sits beside him and takes some 30 pound weights as well. John begins lifting the weights in a steady rhythm with Grayson, but he soon notices Grayson is outdoing him, and John is getting tired.
"Sir, since you've never been to a gym before, I'm guessing, you should start with 20 pound or 15 pound weights." He picks the 15 pounders up easily and hands them to him. Sensei blushes in embarassment, and takes them. He again begins lifting, and this time he is completely steady with Grayson. A little while later, they both stop, rather tired.
"Well sir, we should go get changed now. Good job today." Grayson says, leading the way to the locker rooms. "After you." Grayson holds the door open for Sensei, and as Sensei walks in, Grayson reaches down and smacks Sensei's ass plafully. Sensei blushes extremely hard and walks in.
"Hope you didn't mind that, sir. We guys love patting each other on the butt after some good training." Grayson teases him. Sensei looks in awe as Grayson pulls off his shirt, revealing his nice muscles. He then strips off his gym shorts and boxers.
Sensei's fantasy was pretty accurate: Grayson's cock was a bit bigger than John's. So were his balls. John resists the urge to moan, and strips naked as well to get changed. He quickly glances at both cocks, comparing length, size, and shape. Grayson is truly big in that area. As he looks up, he thinks he sees Grayson eyeing his cock as well. Sensei blushes.
"Let's go to the steam room, sir." Grayson says as he gets changed. Sensei changes and follows him. Sensei then gets an urge to shake Grayson's hand for, as he figures, a "Job well done". He taps Grayson on the shoulder...
BAM! Grayson instinctively grabs the older man's hand, bends down, and tosses Sensei over his shoulder! John lands on his back, and Grayson looks down in terror. "Oh, sorry sir! I've been trained to not let others sneak up on me..." He reaches down and helps Sensei to his feet.
"It's...alright." Sensei says, getting hard. "Let's go."
They head to the steam room, where they both strip down and are wearing only their towels. Grayson sits next to Sensei, and it almost looks like a father-son relationship. Grayson asks, "How do you feel about your rematch with me?"
Sensei responds, "I'm going to do my best, Grayson. You're very strong for a teen."
"You were distracted during our match, sir."
"How so?" Sensei freezes as he realizes Grayson must have noticed. Grayson doesn't do sensei justice with his words. Glancing down at Sensei's enlarged cock, he reaches down and grabs it!
"This is why." He says carefully. Sensei stares down in shock. "Sensei, sir, you have the hots for me, I think." Grayson looks up at Sensei and winks. "I saw how you blushed when I patted you, sir." He begins squeezing the bulge, and Sensei leans back and moans. "You like this, don't you?" Sensei can only nod, moaning.
"You should stop enjoying it so much, sir." Sensei doesn't listen, still moaning. Suddenly, Grayson reaches over and elbows Sensei in the stomach, hard. Sensei doubles over in pain, his towel falling off, exposing his ass as he falls to his hands and knees clutching his chest.
"Remember sir, we're enemies until our rematch. Don't expect the enemy to pleasure you. You should remain focused during our rematch, or else. I am sorry for this, but we must train hard. You are getting too distracted with me. However, I realize you are probably very aroused right now, so here is a parting gift..."
He gets on his knees and grabs Sensei's shoulders, pulling him up. He rubs Sensei's stomach for a few moments, massaging it gently for him. Then he reaches a hand behind Sensei's head and kisses him passionately, while his other hand pats his butt. He then breaks the kiss. "After our rematch, perhaps we can go a little bit further, sir. I am again sorry for hurting you, but this is how it is."
"I surrender, Grayson. I want you."
"No, you'll wait. If you don't fight with everything during our match, I won't go with you."
Grayson stands, turns around, and walks out of the steaming room. Sensei can only stare at Grayson's toweled ass as he leaves...
