Fucking Endurance Training!

As Enzo worms his fingers into my hair, I allow my little brother to take control. He slides my mouth down onto his cock, pushing me to his hilt, and I suck silently as he uses his hands to move me. I moan on him, grinding my tongue around it.

His hips start to move, fucking my mouth as I pick up my pace on Juno. My world narrows to the scent of my little brother and little sister in my lungs, their friend's cock hammering into my ass. I sway, between Hiro and Enzo, as they fuck me.

Yet Enzo only takes four hard thrusts for himself, before passing my mouth to Juno. I switch hands fast, recognising their game swiftly. I look up at them, making eye contact as Juno's hands take over, and she drives my mouth down onto her.

Four slamming thrusts, and she passes me back to Enzo, causing Hiro to grunt in reaction. “Do you two share everything as equally as possible? It's gonna make it harder for me to fuck this bitch if you keep changing the faggot's angle, y'know!”

In answer, Juno slaps me firmly on one cheek, and Enzo promptly hits the other. As Enzo fucks my mouth harder for four harsh thrusts, Juno scolds me, firmly, “Angle your spine, faggot! Keep your hips aligned with his cock while we use you!”

Hiro's fingers twitch on my hips, I doubt he expected the answer to be Enzo and Juno both slapping me. It doesn't matter, as I arch my spine and cock my hips to one side. It's more strain for me, but I'm a faggot, their pleasure is literally my job.

Behind me, Hiro groans in pleasure as I clamp my muscles down around him. His pace resumes, fucking me hard and fast, no longer attempting to match his pace to anyone. As Juno reclaims my mouth, I gasp for air in between their thick cocks.

“Fuck, he's really obedient, isn't he?” Enrique murmurs aloud, his voice rich with wonder.

“It's the brainwashing!” Juno grunts the words out, “Thank Amy for it, when you meet her.” Enzo grunts an agreement, or a confirmation. I can't really tell which it's meant to be when it's literally just an mph. I highly doubt their friends can tell.

My eyes flutter as my mouth is switched back again, while I can feel Hiro's heat building inside my ass. Hiro holds out, for sixteen minutes, before he slams in and holds it, watching the twins share my mouth. I groan on Enzo's cock as I take him.

I can feel more cream rolling down my thighs, thick and heavy, until Hiro's pulsations end. I tighten my ass around him to milk his cock as best I can, but having taken three cocks, I'm becoming well-stretched. My eyes flutter, looking up at Enzo.

When Hiro withdraws, I hear movement, and see their friends leave the room for a shared shower. I can assume it's Julia's intended to be watched over by Enrique and Hiro, a form of aftercare for a Dominant Top, rendered by two similar souls.

Alone with my little brother and little sister, the twins take turns fucking my mouth harder, extending their run to seven strokes instead of four. As I have no one else to focus on, I moan lovingly on them, stroking Enzo's thigh, and Juno's shaft.

When Juno reclaims my mouth, I switch to stroke her thigh while handling Enzo's cock with my hand. I can feel them each pulse, then their pace dramatically slows. I moan, worshipping Enzo's prick with my mouth as he pumps into me, slowed.

The movement of my hand on Juno adjusts, and I match that pace on Enzo when Juno reclaims my mouth. The twins want to edge themselves, now, and even if I had the right to protest, there's no way in hell I would. I'm enjoying servicing them.

Achingly aroused, myself, I bob my head in time with the thrusts delivered, until their pace increases once more. For forty minutes, the twins drag it out, edging down and then building up four times, until I hear footsteps returning to the room.

“Dude, you two still aren't done with the faggot's mouth?” Hiro asks, “How the fuck much endurance do you two have?”

“How late can you stay?” Juno asks teasingly, and I can hear the sound of two of them scoffing, but Enrique fires shots.

“Fuck you, bitch, damn, that's how late!” Enrique snarks, and I hear him grab my computer chair and whip it around. I see him sit down backwards on the chair, freshly redressed, but with his cock out, as before. His watches me taking their rods.

“You'd never know this slut's your big brother!” Julia observes, “He doesn't seem to have any of the normal reluctance or resentment. If I made my big brother my bitch, he would be so mad. I mean, he's also not a submissive cocksucker, but ...”

“Yea. Even still,” Hiro says, “My older brother is very submissive-inclined. His Dom is handsome, and my brother's highly obedient. If I went over to their house and told him to suck my cock, he'd beat my ass, but his Dom would be entertained.”

“Drink, whore!” Juno commands, as she pulls my mouth up her cock until only the crown remains. Enzo shoves his crown past my lips, and twin ropes of cream pump into my mouth. I start to swallow fast as I'll be in trouble if I should waste any.

“You two taking his ass, now? Don't know how tight he is after all three of us have had him!” Enrique pipes up, as I moan, swallowing until the pulsing subsides. I wait, as Enzo and Juno slide their fingers to their hilts and then stroke, once, up.

I lick the last drops from their crowns, and then Juno sinks down. Enzo circles around behind me as Juno slings herself in underneath me, sliding between my legs. I breathe in slow, then look down at my little sister and smile at her lovingly.

“Man, your faggot really really adores you two,” Julia murmurs, as the twins prepare for the final round, with an audience.
