In retrospect, this is entirely his fault for letting Enji know he would go to his town in two weeks because Hawks wanted to spend his birthday with his favourite grumpy old man.
Don't touch yourself until then. I forbid you.
It seemed pretty easy at first. Piece of cake. It isn't like Hawks is that much of a pervert he can't spend a day without pleasuring himself... It's just inconvenient. Jerking off is a stress relief, a habit, something he does every day without even thinking about it.
But now he's hyper aware of it, because the psychology of telling him not to do it just worsens things. Now he's thinking about it way too much. And the desire to do what has been forbidden grows with every minute that passes by.
The only thing holding him back is that Enji didn't say it by text. He said it on a phone call, deep booming voice commanding him and melting Hawks onto the ground.
So he wants to obey his daddy, he wants to show him how good and well-behaved he can be for him.
He really, really does. But it's like impossible. The more he thinks about it the more he wants to do it.
So he gives up after a week and a half and fucks his own fist quickly while thinking about getting punished for it. Thinking about an enormous hand leaving heated prints on his ass while he cries and screams and drools all over himself.
"You spoiled yourself, I'm not gonna touch you." That's what Hawks gets when he arrives at his boyfriend's place and he wonders how the fuck Enji knows that. Sometimes it seems the man has all of Hawks expressions cataloged on his brain or something.
Hawks shrugs and they just sleep that night, but he's tired from the flight anyways, he'll just try again tomorrow.
He wakes up at his birthday's morning to find Enji reading a newspaper, siting calmly on the couch with his reading glasses on. The winged hero doesn't understand newspapers at all. He'd been raised to be quick and efficient, and obtains information via internet which is done much faster and better than a paper could. But Enji's old-fashioned and his turquoise eyes scan the news with no hurry, reading all those columns that bring yesterday's news.
Hawks' stomach growls a bit, but he isn't really interested in breakfast. Not when he has a meal right in front of him.
Enji's legs are apart and he kneels, intending to get in the middle of them. Enji, it seems, is having none of it and changes his position so the blond can't fit there without looking at him, still focused on reading.
"Pretty please?" Hawks purrs with his best innocent performance.
"No."
"I've learned to behave, I swear." He tries once more, bating his long lashes and pouting, trying to melt the old sap's heart so he can get into his pants.
"You never learn."
"It's my birthday I deserve a nice present. A nice, thick, gigantic present."
"Then you should've obeyed me." Enji haven't even taken his eyes off the newspaper yet.
Hawks then starts to touch his legs with naughty hands and mouth his crotch through the fabric.
"You think you're gonna get my attention by showing just as much of a whore you are?"
"Well, that usually does the trick"
Enji doesn't look impressed. He pays no attention to Hawks, sharp eyes scanning the pages like it's the most interesting thing in the world.
"You're so mean, you know, you're lucky to look sexy as hell even when you're ignoring me." Hawks says as he jumps on top of Enji's thick thigh and positions himself there.
Enji doesn't even flinch, like having a full-grown man dropping all his weight on a single thigh of his doesn't bother him in the least. It probably truly doesn't. The man is pure muscle, Hawks weight shouldn't even tickle him.
The thought makes Hawks almost instantly hard as he presses himself against the strong muscle underneath him.
"If you refuse to give me my gift, I'll take it myself." He says while rolling his hips and grinding on the man's thigh.
"I'm a simple man, ya know, I can get off using anything, just watch me, Endeavor-san." He doesn't, but Hawks can't bring himself to care that much while his cock rubs on the warm thigh, ruining Enji's slacks with pre-cum.
"This is just what I used to do with my Flame Hero body pillow. Just rub myself on it until I came." He stars blabbing as the friction gets good, he always gets talkative while feeling good. "On your thighs, your ass, your tits, your face, oh god, I wanted to shove my cock in your mouth so bad."
"I still do, ugn, still wanna fuck your mouth and hear you say how pathetic I am, how you don't even have to make an effort to swallow it all."
Suddenly Enji doesn't look that impassive anymore. Hawks knows he's trying to be stoic, to block his blabbing and continue to read, but that's exactly why he's talking that much. He'll have to pay attention to him from annoyance. And any attention is good attention.
"You're so thick, your fucking thigh is bigger than my whole body." He rolls his hips to emphasize what he's saying, the firm flesh underneath him so hard and goddamn hot. "I used to watch videos of you and think no fucking way this man cannot be real, no one has the right to look that that. But you do, and I just want to cover your whole body with cum"
He sees tiny flames flicking on Enji's face out of his control. Good. The old man liked control so much, but he can't even handle a little teasing. Sucker.
"Take it easy, hot stuff. You're gonna burn your precious newspaper like that." Hawks laughs breathlessly and a hand comes down his ass to hit him so fucking hard and burning that the pain would be too much if he didn't like it. He cums almost instantly, squirming on Enji's lap and spurting all on the older man's thigh.
He's still laughing though, after all he got exactly what he wanted anyways.
"Now wish me a happy birthday, c'mon, I deserve it." He says by Enji's ear while he catches his breath, dropping his weight on the man's shoulder.
"You don't." He still sounds mad. "But happy birthday, insufferable brat."
