13. Will #2

The moment I lock my eyes back on him, I forget everything else.

My mind is blank except for the vision in front of me, as Ari opens his pants and lets them drop around his ankles.

He lifts the bottom hem of his shirt to show off the thin, satiny black straps of a pair of underwear so small they barely hold him in.

Ari does a slow turn, tying the shirt behind his back to keep it out of the way, showing off the open back of the strappy jock that perfectly frames the smooth, pale globes of his round, pert ass.

Seeing him this way sends goosebumps down my thighs and ass and over my balls.

When he’s facing me again, he sits at the edge of the bench and leans back against the wall, stretching out his lithe body as he runs a hand down his chest and abs. He squeezes his erection through the straining material. My mouth waters for him to take it out. I think I might mouth the words.

Ari’s eyes flick down to my crotch and back up, a wicked gleam sparkling in his eyes.

With two hands hooked in the straps of his waistband, Ari pulls his underwear down to just under his balls, letting his cock spring up and hit his abs. He pushes them down past his knees to his ankles and then spreads his legs as much as he can.

I can see everything. Or, enough of everything to make it so I’ll never need to watch another porn ever again. There are too many shadows to make out all the detail that I’d like, but maybe that’s a good thing. If I were any closer, I’d be hard-pressed not to reach out and touch. Lick. Suck. Taste.

Oh hell, what would he taste like?

Do I have any idea what I’m thinking? No. Have I done any of that stuff with a man before? No. Have I ever had another man do any of that to me before? Another no.

But I’ve always known there was something very non-straight about the way I looked at Ari. It’s honestly not even on the list of reasons I shouldn’t be doing this.

Most importantly: he’s my brother.

Foster brother, yes. But that doesn’t change the fact that we grew up together. Or that I love him like a brother, even if there is more to it. Or that I’ve always felt a responsibility towards him. Or that the whole world sees us as brothers and would never understand.

None of that stops me from watching with rapt attention as Ari fondles his balls and slowly strokes up his shaft.

His cock is long and thin, uncut with a fat mushroom head.

He’s hairless and so smooth, and it makes me want to rub my cheek along the insides of his thighs and nuzzle against the base of his dick just to see if it’s as soft as it looks.

I can’t decide if perfect smoothness or the slightest bite of stubble would be hotter.

Ari swipes his index finger across the head of his cock, over the weeping slit, and brings it to his mouth. He licks the bead of precum, and I want to chase it into his mouth with my tongue, which dips out to lick my lips as if in anticipation.

His lips curve up, pleased with the show he’s putting on.

I’ve kissed those lips. Gently. Carefully. I’ve touched that body. Tentatively. Fearfully.

What I wouldn’t give to ravage him entirely.

Flattening his palm, Ari licks the flat of his tongue across his hand and returns it to his dick. I nearly fall off the bench, but my eyes follow the action, and I watch, mesmerized, as Ari starts to pump himself.

I don’t even realize my own hand has traveled to my crotch, pressing down and rubbing along the length of my straining cock. Shit, this wasn’t part of the deal.

But when I flick my eyes back up to Ari, he’s biting his lip, nodding.

“Do it,” he mouths.

Thoughtlessly, like I’m being pulled by a motor and not by my own volition, I unfasten my pants and reach inside to palm and stroke myself, watching Ari’s rhythm and matching it. I hear a whine and look back up to see Ari straining his neck.

“Can’t see.”

Shit. This is so wrong.

Opening my pants all the way, I pull my cock out of my black boxer briefs and stroke it right out there in the open.

Ari and I have seen each other’s cocks, obviously.

This isn’t our first foray into the world of kink.

But this is the first time we’ve watched each other with the intent of getting off to and for each other.

It’s the first time we’ve purposefully crossed the line.

He’s always liked being watched, and I liked watching.

Back then, I might have had a girl in my lap, but she was little more than a shield so Ari and anyone else there didn’t know that it was him that was doing it for me.

But there’s no hiding it now.

“Jesus. Fuck.” I hear someone to my left say, and briefly glance over to see several people watching Ari with their mouths hanging open. More than one of them is touching themselves, and a surge of something has my chest rumbling with an animalistic growl.

“Mine,” I say, when two of them look my way.

Their eyes drop to my dick, watching me for a moment before returning their eyes to Ari, then back to me, then Ari. Back and forth they jump like they’re watching a tennis game. I’m at the edge of my seat, seriously considering standing in front of Ari so no one can see him but me.

“Eyes on me, big brother,” I hear Ari pant, and I’m fucking done for.

My eyes are wide as I turn back to him, mouth gaping as I process what he just said.

“What did you— Fuck !” I shoot everywhere, ropes of cum spurting on the floor between us, all over my suit pants, and filling my hand.

I come so hard I can barely keep my eyes open to watch Ari follow me over the edge, painting his stomach in pearly fluid.

By the time it’s over, I’m gasping for breath. From the orgasm, the rush, and the absolute terror over what we just did. I don’t let it show on my face though, knowing it’ll hurt Ari if I give him any sign that wasn’t okay. It was more than okay. It was…

Okay, it was absolutely not okay.

It was filthy and wrong and terrible in the most delicious way.
