The fact that Eren doesn't come immediately should honestly be considered a miracle. He clamps down hard on his self-control, trying to stay as still as possible while his two Doms rut against him: one against his cock and the other against his tongue.

The Corporal is using one hand to pin Eren's wrists down onto the mattress, but his other hand is slowly brushing the head of his cock against Eren's tongue. Eren desperately wishes he could take the whole thing into his mouth and suck on it for a few hours, but he lies still and endures the teasing.

Eren's not completely sure if Daddy and the Corporal do it on purpose, but he's pretty convinced that they had collaborated on how much cock they give Eren in their one-on-one scenes with him. The Corporal very rarely goes as far as even unzipping his pants when they're playing together. Generally during their scenes, he keeps the majority of the focus on Eren's body and the sensations he can inflict upon it. The refusal to allow Eren to feel or even see the Corporal's cock only makes Eren want it more. He suspects the whole thing has a lot to do with the relationship between Daddy and the Corporal, and the hierarchy of their three-way dynamic. Eren knows that when Daddy and the Corporal play together, the Corporal submits to Daddy. He's only had the privilege of actually watching his Daddy completely dominate the Corporal a handful of times, and usually he's been blindfolded for it.

Daddy really likes having control. He loves the fact that he decides when and if Eren is allowed to come. He loves having both Eren and the Corporal as his submissives. And he loves watching the Corporal dominate Eren with pain and almost-pleasure. Eren has a strong suspicion that Daddy is just as controlling about the Corporal's orgasms as he is about Eren's. It's very likely that Daddy tells the Corporal when he is and isn't allowed to take pleasure from Eren's body, and when he's allowed to let Eren out of his cage and beat an orgasm out of him. It's a great strategy, Eren thinks. That way, both Eren and the Corporal have to rely on Daddy for any sexual pleasure or release.

It's all very manipulative, but Eren knows it's happening and he's one hundred percent sure that the Corporal also knows that it's happening. Daddy has complete control over how the three of them interact when it comes to scenes and play. It adds a unique dimension to the dynamic.

It also means that Daddy has most likely coordinated the majority of the scene tonight. And Eren knows how much Daddy hates letting Eren come.

"Poor baby," Daddy croons as Eren starts involuntary shaking from his efforts to keep still. The words are emphasized with a particularly drawn-out rut against the bulge in Eren's panties. He groans as he feels the heat of his Daddy's cock pressed up against his own. Combined with the barely there taste of the Corporal, it makes Eren want to scream.

Eren can hear the heavy panting from the Corporal. He gets the feeling that he's not the only one being teased from this not-quite blowjob.

"How does it feel?" Daddy asks softly, clearly speaking the Corporal. When the Corporal replies, his words are strained and his breathing is shallow.

"So…hot…" The response accompanies a particularly hard thrust into Eren's mouth before the Corporal quickly moves back again.

"I bet having his whole mouth on it would feel even better." The way Daddy is talking to the Corporal gives Eren goose bumps.

The Corporal grunts out a response that Eren can't quite hear.

"What was that? I couldn't hear you." The mocking tone of Daddy's voice makes both Eren's temper and arousal flare.

"P-Please…" the Corporal replies.

"You know the rules."

Unfortunately Eren doesn't know the rules, so he's not sure how to go about expediting Operation Get-The-Corporal's-Cock-In-His-Mouth.

Eren wants to wail in despair when the Corporal pulls away completely, fighting off the urge to lean forward and reinitiate contact.

Suddenly Daddy's thrusts start speeding up, and Eren can feel Daddy's hand pressing his cock up against Eren's.

No. It can't be.

"Mmmm…"

Fuck! That's Daddy's tell when he's getting ready to come. Eren hasn't even gotten the chance to really get his mouth on the Corporal's cock. How the hell is he supposed to make the Corporal come if he can't even try—

Oh. Of course.

Control. It all comes back to control.

There was never an "if" in Daddy's plan for tonight. The game is rigged. The game is always rigged.

Eren wasn't allowed to come if Daddy managed to come before the Corporal, but the Corporal isn't allowed to make himself come before Daddy.

That must have been what Daddy meant when he said you know the rules.

Eren doesn't know if he wants to laugh or cry when Daddy's thrusting stops and he feels the distinct sensation of hot come landing on his panties and stomach. He can feel tears prickling behind his closed eyelids.

Crying it is then.

"Now," Daddy says.

The blindfold is ripped off of his face and suddenly Eren is looking up into the crazed and wild eyes of his Corporal. Right as he feels the first tear sliding down his cheek, the Corporal slams his cock into Eren's mouth all the way to the root. He starts up a brutal pace as he thrusts in and out, forcing Eren to gasp for breath each time he pulls back. It only takes a few seconds before the Corporal is letting out a small noise and plunging his cock down Eren's throat. Eren works his throat muscles as he attempts to swallow down all of the Corporal's come.

After a few moments, the Corporal pulls back, slipping all the way out of Eren's mouth. Eren gulps in lungfuls of air as tears continue to run down his cheeks.

"There there," Daddy murmurs as he moves Levi off of Eren's chest to lie down next to him. Eren immediately reaches out and pulls Levi close, sighing softly when he feels slender arms wrap around his torso. He closes his eyes and snuggles into Levi's warmth, listening to the sounds of Daddy moving around the house.

Seconds later, Daddy comes back with juice and warm washcloths. Levi and Eren sip their drinks while Daddy wipes them down. Once the glasses are empty, Daddy takes them back to the kitchen. Eren's eyes slip shut again until he hears Daddy's voice speaking softly.

"I'm sorry, love. One more thing."

Eren's eyes flutter open to look at Daddy. It takes a moment for Eren to register the ice pack in Daddy's right hand and Eren's cock cage in his left. His eyes widen and he tries to scramble backwards, despite knowing that trying to escape is futile. Eren knows that he can use one of two words to make the ice pack go away, but he doesn't feel like he needs to use either one of them. Rigged as the game was, Daddy had told him that he wouldn't be coming if Daddy came first.

Eren still whimpers when Daddy crawls onto the bed after him.

"Do you need to be held down, love?"

Eren thinks about it. He knows that an actual attempt at escape without use of a safe word will result in punishment, so it's not as if he is actually planning to flee. But then again, he's always found comfort in restraint, and he figures he should do his level best to make this experience as comfortable as he can, laughable as the idea is. Eren's gaze drifts over to Levi, who is watching him with tired yet attentive eyes.

"Yes please, Daddy." Eren says, resigning himself to his fate. At his reply, Levi reaches for Eren's wrists and once again brings them down on the mattress above his head. Eren turns to watch as the ice pack comes closer, but at the last second his vision is blocked and Levi is pressing a kiss to his lips. As pleasant as it is, even the distraction of Levi's talented mouth isn't enough to keep him from screaming out when he feels the ice pack press against his still hard cock.

He's very grateful he had asked to be held down because now he's thrashing about and trying desperately to pull away from the agony in his groin. Thankfully, Daddy decides to show what little mercy he has and doesn't prolong the experience too much. The ice pack is pulled away and his cage is swiftly and deftly replaced in a matter of seconds. Eren's body goes lax as soon as he hears the click of the lock. Levi releases his wrists but presses close to nuzzle at Eren's neck and press kisses to his cheek and jaw. Eren whimpers and gratefully cuddles close.

"My sweet, sweet boys," Daddy sighs fondly as he rises once more from the bed to put away the ice pack and turn off the lights.

Eren is starting to drift off to sleep when he feels Erwin slip into bed behind him and press up against his back. Erwin reaches out to lightly stroke his thumb against Levi's cheek while at the same time pressing a kiss to Eren's hair.

"Sweet dreams, darlings."

A/N: Thank you so much for reading! I am already working on a second part to this series which will tell the story of how Eren met Erwin and Levi, and how the three of them came to be in a relationship.
