A/N: I haven't wrote a story in a while so I'm sorry if this sucks XD. Let me know what you think!
The sports festival was getting boring, and as much as All Might loved watching the students rise to the top, he needed a change in routine. He sighed and went inside the building for a short walk.
As he rounded the corner, he spotted the number two hero Endeavor, who he hasn't spoken to since that incident nearly ten years ago.
All Might quickly transforms into his hot muscular buff form, blocking Endeavor from leaving.
"Ah, if it isn't the number two hero Endeavor!" He shouts, uncaring of the glare he received in return.
"Move out of my way, All Might. I have better things to do than to chat with you," he sneers, turning away only to be stopped by All Mights rippling arm of justice.
"But we haven't spoken in quite a long time." He casually throws an arm around Endeavor, almost crushing his broad shoulders."Why don't we catch up before the match between young Todoroki and young Midoriya?"
"Like I said earlier, I have no business with you," he seethes, his flaming mustache flaring in anger. "Now, move out of my way."
All Might takes his arm off of those warm shoulders and lets Endeavor walk away before suddenly running up to him, shouting and tumbling into him. They roll around and end up by a waiting room. All Might shoves him in and follows behind, locking the door shut.
After a moment of stunned silence, Endeavor attempts to shove All Might off, only for his buff arms to be pinned by the big, strong hands of his rival.
"AllMight?!" he yelled, his face reddening in anger at the determined face of the number one hero, not liking where this was going.
All Might flips Endeavor onto his hands and knees, pulling rope from inside his asshole.
"Now, this might hurt a little, but do not fear—"
He ties Endeavors wrists and legs tightly, moving to tie the extra rope to the leg of the table.
He grins at the look of anger and horror across Endeavors face.
"I swear All Might, untie me right now—"
"BECAUSE I AM HERE!" He shouts loudly, ripping Endeavors clothes off all at once with his powerful hero fingers.
He sees Endeavor about to burn the rope, but before he can, All Might pulls out a bottle of scented lube, and shoves a coated finger up his ass.
The effect is immediate. Endeavor shouts in rage and confusing arousal and All Might licks his lips. He enters two more fingers before he decided to speak.
"So," he starts casually, like they're not about to have sex in a waiting room, "how have you been, Endeavor?"
"All Might get your fingers out of my ass and untie me! I have a fight to watch!"
"As do I. But the fight doesn't start for another half hour. I'm sure you have nothing better to do before then."
He brushes his fingers against his prostate. Endeavor moans and his fire almost burns All Might. He just laughs and brushes against that spot a little longer before tearing his clothes apart.
"A-All Might.. Only this once will I give in. So make it quick!"
"Of course, we're on a time limit after all."
All Might positions himself behind Endeavor again.
"Are you ready?"
"As ready as I'll ever be."
"It's gonna hurt."
"I'm the number two hero. I think I'll survive from a dick shoved up my ass."
'Well,' All Might thinks, 'I'dbestnottellhimmysizethen.'
All Might slowly pushes in until he's fully sheathed inside Endeavors raging volcano.
Endeavor grunts and claws at the floor in pain.
After a few moments, All Might pulls all the way out.
He pushes back in with a shout:
"FLORIDA SMASH!"
He pounds in and out relentlessly, and soon Endeavor only feels pleasure. He yells when he prostate is abused and All Mights hand grips his flaming cock. His giant hands cover it completely and it feels like heaven.
A familiar heat pools in the pit of the number two hero's stomach, aching and expanding until it becomes too much. He comes with a shout, fire coming out instead of sticky white fluid.
All Might finishes not long after, shooting One-For-All into Endeavors anus. After they come down from their high, Endeavor burns the rope and somehow repairs his clothing, All Might doing the same.
"Just so you know, there won't be a next time, All Might."
All Might nods, giving Endeavor a steamy kiss.
In the end, it becomes a regular thing. Endeavor is just a tsundere who doesn't understand love. But All Might does; he is the symbol of peace, after all.
Only when Endeavor finds out that these feelings of his means he's gay does he burn All Mights house down in a fit of rage.
