Holy Shit, Big Brother: An Unexpected Omega Pregnancy

Roy swung open the door to their shared bedroom, his nose immediately picking up on a change in Mar's scent. He paused for a moment, taking in the musky, earthy aroma that was now emanating from his younger brother.

"Holy shit, Mar, you smell different," Roy said, his voice low and husky.

Mar blushed, his cheeks turning a deep shade of red. "Shut up, Roy. It's nothing."

Roy raised an eyebrow, a smirk playing at the corners of his lips. "Nothing? You reek of Omega in heat."

Mar glared at him, his eyes narrowing. "And you reek of arrogance."

Roy chuckled, his amusement clear. "Well, someone's feisty. Come here, little Omega."

Mar tried to resist, but his body betrayed him, drawn to Roy's heat and strength. He took a step forward, then another, until he was standing right in front of Roy.

Roy pulled Mar onto his lap, his arms strong and secure around his waist. "Yes, you do. Your body is begging for it."

Mar squirmed, trying to push Roy away. "Stop it, Roy. I'm your brother."

Roy nuzzled Mar's neck, his breath hot against his skin. "And you're my Omega. It's natural."

Mar gasped as Roy's fingers brushed against his entrance, his body responding instinctively to the touch. "Roy..."

Roy smirked, his eyes glinting with mischief. "Yes, Mar?"

Mar glared at him, his frustration mounting. "You're such an ass."

Roy laughed, his deep voice rumbling through Mar's chest. "And you're such a tease."

Mar moaned as Roy entered him, his body finally giving in to the desire that had been building all day. "Roy..."

Roy purred, his hands gripping Mar's hips. "Yes, Mar. I'm right here."

The two of them moved together, their bodies fitting together perfectly. Mar couldn't help but let out a moan of pleasure, his head falling back against Roy's shoulder.

Roy's lips found Mar's neck, his teeth gently nipping at the skin. "You like that, don't you?"

Mar nodded, unable to speak. He was beyond words, beyond thought. All he could feel was the heat between them, the connection that was stronger than anything he had ever known.

Roy's fingers dug into Mar's hips, his thrusts becoming more urgent. "Come for me, Mar. I want to feel you come apart in my arms."

Mar let out a cry of pleasure, his body shuddering as he reached his climax. Roy followed shortly after, his own release sending waves of pleasure through Mar's body.

They lay there, tangled together, their breathing heavy and ragged. Mar's head was still resting on Roy's shoulder, his body still humming with pleasure.

Roy's arms were still around Mar, holding him close. "I love you, Mar," he whispered.

Mar smiled, his heart swelling with love. "I love you too, Roy."

They lay there, wrapped up in each other, their bodies still entwined. The heat between them had not dissipated, but it had changed. It was no longer the heat of desire, but the heat of love. And it was a heat that would never fade.
