Title: Planning

Rating: NC-17

Pairing: Gabriel/Sam

Prompt: Gabriel in heat completely sub when normally they fight for control

Notes: Unbeta'd

Never let it be said that Omega's are submissive in bed because whoever says that are fucking liars, straight up fucking lairs, and if you say that to an omega you will more than likely never see the light of day again. Which makes it a surprise to see Gabriel like this.

They had been planning on a date, Sam showing up right on time just to walk into Gabriel's apartment and smelling the sickly sweet scent of an omega in heat.

They had never slept together when Gabriel was in heat – inhibitions to low, hormones to high – so it hit Sam like a punch in the gut.

Sam was in the process of trying not to track down the owner of that smell, falling to his knees in attempt at self-control, when the smell became stronger.

"Sam," a raspy voice called out. "Sam, please."

Gabriel never begged, ever, and so Sam had to look up, only to shut his eyes tight at the picture in front of him. Gabriel was naked on his knees, eyes lowered and throat bared in submission. Holy shit, that was hot.

"Please," Gabriel rasped out again, lowering himself again onto his forearms. "Please, Alpha."

Any control Sam might have had snapped in that moment, fingers coming to tip his pants open. He hobbled over to the omega, pants around his thighs.

Gabriel was completely soaked, skin shiny with perspiration and slick. His hole was gaping obscenely wide – like he had been fucking himself on a dildo, and that thought alone would have had him hard – and dripping with slick. Sam couldn't stop himself even if he tried.

He thrust in hard, all the way to the hilt, knot already swelling at the base. Sam's hand came up, gripping the back of Gabriel's neck as he thrust forward again.

Gabriel melted under the grip, body rocking forward, roughly rubbing against the carpet. They were going to have so much rug burn tomorrow – not that either of them cared at that moment.

"Mine," Sam growled, teeth coming to replace his hand. He rocked his hips three more times before he thrust his knot in, teeth sinking in Gabriel's neck. Blood filled his mouth, sharp copper hitting his nose.

Gabriel sighed, falling slack against the floor, smoshed by Sam's heavy weight. His come made a puddle that was really gross but his muscles protested when he tried to move out of it.

"Oh my god," Sam gasped out, trying to move away from Gabriel. Gabe hissed, knot tugging painfully on his rim.

"Stop, Sam." Gabriel sighed out, now fully sated and ready to fall asleep.

Sam was trembling behind him and he could feel the held in words. "Gabe, I'm so sorry, so fucking sorry. I didn't mean to. As soon as we unlock I will leave and you never have to see me again," The words tumbled out, tears flowing freely down Sam's face. He'd royally fucked up – one of the best things in his life and he had to go and take advantage of him.

"Sam," Gabriel called out, amusement coloring his tone. Sam took a deep breath before letting it out. Gabriel took that at a sign to continue.

"You didn't take advantage of me, I wanted this. You know I wouldn't have asked you. Omegas are lucid and in control when their heat hits, ask your brother if you don't believe me – I'm sure Dean with holds sex from Cassie just to tease him. Alpha's love omega heat scent, " He finished lightly. He could feel Sam scrunching his nose up in disgust as another spray of come coated Gabriel's insides.

"Ew, Gabe, I really don't want to talk about your brother and my brother going at it. That is a line I will not cross." Sam shot back. Gabriel laughed, full body quaking with laughter.

Sam smiled sadly at the back of his mate – and holy shit that was kind of scary – heart still heavy with guilt as what he'd done.

"Sam," Gabriel said after a moment, breaking the silence. His voice was heavy with exhaustion, heats took a lot out of Omegas. "Sam, I'm serious, I called you and set up the date for a this very reason. I hope you have nothing to do for the next few days."

"What?" Sam said in disbelief.

"Really, Sammy-boy? You really think I don't know when my heats hit?" Gabriel asked teasingly.

"You planned this." Sam states. "You ass," He said affectionately, bending down to kiss Gabriel's spine.

Gabriel hummed, grinding back against Sam's knot. "I would love to go another round but let's only get a mild case of rug burn, 'kay?"

Sam smiled sucking a mark on Gabriel's shoulder feeling affection curly through him again. "Okay," after a moment, "I love you," whispered with utter conviction.

Sam could feel Gabriel roll his eyes in fake exasperation. "I love you too, you big moose."
