Hear me out, what about something like...?
Sick&Widowed!Peter x Superior IronMan! Tony
The first time they've met is when SI is hosting a funeral (more like public humiliation) for all the Avengers that died while trying to fight him.
Is it ironic that god-like Tony Stark ever cared ? Yes. Does he enjoy the attention while giving out small mercies for peasants? Also yes. It helps out his reputation while also pick-pocketing a few hateful glares here and there from the former Avengers. (They weren't there at the funeral but he knew they would be pissed off, mad even) and also gain more loyal dogs who willingly beg for a drop of his Extremis.
There caught his eyes in a corner, a young, lean frame dressing in a black suit with a black veil, his face is covered but Superior knows that's a hella pretty face, the kind he wanted to see cry out in pleasure on his bed. He's sure of. His hands clutching a worn out handkerchief, there, Superior saw it, the golden ring on his finger. His right fingers brushed against the golden band, his action is slow, like he's lost in thought, his hand is small delicate, kind of hand could never wield a gun, it makes Tony itch to take the hands and bite it.
The young figure caught his stares, his body shook as if he was stunned and didn't know what to do next facing Tony, he quickly averted his eyes.
Later on when it was time to bury all his opponents, that same figure stepped up and placed flowers on a certain coffin. Tony doesn't recognize the face or rather he didn't bother to, no one is important really.
"Here lies a son, a friend,"
That young figure gets on his knees.
Tony is drawn to Peter like a moth to the flame.
It all started out with the funeral, is it fucked up that he's interested in a widow the day their husband died by his hands ? Probably but that doesn't stop him from approaching the scary smart widow.
Peter is a pain in HIS ass. He carried out his late husband's plan to fight him to his last breath, many times Tony almost fell into his traps only to come back with the growing hunger he carries towards the widow. The pained, hatred eyes that never ceased to leave him with a face full of tears half hidden behind the veil, it's just another pest, he thought, oh how wrong was he ?
If patience is a virtue then Peter must be a saint, he lies low, plays weak, smiles pretty, lures his prey (Tony's men) causing him endless trouble.
He knows Peter's body is fucked up, a total mess and the only thing that can keeps Peter's alive is ...his Extremis. How ironic must it be huh ? The only way he can live long enough to kill his husband's murderer is to take up the same murderer's mercy. He can see the way his body trembles slightly when taking action, how his left foot can barely hold his body straight, his breath became erratic after a few minutes, the coughed up blood here and there. He's dying but also not. The hatred flames in his eyes grew strong, it drew Tony in it. Burn him alive.
They've each other countless times. But there were only 1 times where Peter managed to take him down. It was a genius plan, Tony admitted.
Still having the same black veil covered his face, Peter approached Tony with caution, but Tony could see how his legs were shaky.
"Boss, system reboots in 30 secs" FRIDAY said in his ear pieces.
Peter sits on top of him.
Veil took off and revealed a pretty face with messy brown curls hugging his cheeks, glassy brown eyes staring at him with a pained expression.
His hands raised high up.
And down he goes, knife pressed against his throat.
Peter's body trembled uncontrollably, tears had started to run down his face and fell on Tony's armour.
Tony quickly regained the control of the situation, now having Peter pinned down, he could see his face better.
He brought Peter back to his tower, there began their push and pull story. Tony is an irresistible man but Peter was more than Tony thought, he was smart, pretty, loyal, thoughtful,... All and all but not for Tony, it was for his late husband, the one Tony killed. It's like his affection gaze will never be Tony's, nor will his late night caress on his cheeks, neither could be the kiss on his arc reactor or the ring on his finger.
And Tony killed his husband.
Tony has never bargained in his life. Maybe his old self did (for the love he could never have) but Superior didn't because why bargain when he could have everything spread out perfectly on a silver plate for him ?
He never believed in god because again he has never bargained for something, he has never prayed for anyone. He is THE god himself.
He has never begged. Never on his knees in desperation, tears ran wild on his cheeks, wet his shirt collar leaving him disheveled like ever.
But right now, Tony wanted to bargain with death.
He wanted to bargain with Peter.
Tony Stark - Superior Iron Man, on his knees beside Peter's bed. The figure lay there, short breaths, dry laugh, his skeleton hand held firmly onto Tony's, another cough went by taking almost all his remaining life force out.
Superior didn't respond, his eyes glued onto the monitor on Peter's left where a dozen bags of Extremis hung low trying to get injected into the younger male's body but the monitor keeps on repeating the same message "injection failed, body is incompatible with Extremis"
"Just like I did back then..."
"Why ?" Tony brought Peter's hand to his arc reactor, the blue light flickers.
"I thought I had abandoned my husband's plan, were you ? Fight you was never on the plan, the plan is to get people out of Extremis. This is the result," he pointed at himself.
"As for your other question...Why didn't I kill you before you capture me" He locked his eyes with Peter's, the hatred was still there buried deep down in those brown eyes, but the flame is gone, it's replaced by something triumphant.
"Death isn't the only penalty"
The frail body collapsed into his embrace, the warmth on his skin quickly turned cold and the breath slowly decreased by how long his chest took to go up and down.
"Boss ?" FRIDAY - still carefully monitor the vital chart.
"Increase the Extremis dose"
Injection failed, body incompatible.
Injection failed, body incompatible.
Injection failed, body incompatible.
It turned out Tony has never successfully escaped Peter's trap. He's too slow to comprehend how, was it the time where Peter first interrupted one of his plans ? Was it the time where Spiderman - despite being deeply wounded somehow managed to rip his one piece out of his armour? Was it the time where he saw his face covered by a veil ?
The second funeral Tony attended after becoming the Superior Iron Man.
He stood where Peter did years ago.
"Here lies, a son, a friend, a hero"
Death isn't the only penalty.
Those words ring in his ears loud and clear.
Tony's finger brushed against the made up tin ring on his finger, the kind of ring made out of scraps that can be found anywhere in his labs.
He's right. Death isn't the only penalty, Peter knew.
The day they met, Peter knew what the perfect plan of revenge was.
Now dressed in black suit, a veil covered his face and a ring made out of scraps.
Tony Stark is a weeping widow.
Don't know tf I'm doing...
