Callie leaned back on her chair, feeling the lingering effects of her heat slowly dissipating from her body. She sighed in relief, grateful that it was over for another trimester. Just then, the door to her office burst open, startling her out of her thoughts.
"Dr. Torres, we have a situation in the ER. Dr. Cristina Yang is requesting a consultation whenever you are available," Heather, one of the hospital's nurses, said, panting slightly from running down the hallway.
"Okay, I'll be there in a minute," Callie said, rising from her chair and grabbing her white coat. She was about to leave when Heather stepped in front of her, blocking her path.
"Dr. Torres. Can I talk to you for a minute? It's important," Heather said, her eyes darting nervously around the room. Heather is omega. A busty nurse with short blonde hair. She always had a crush on Callie.
"Sure, what is it?" Callie asked, a little annoyed at the delay.
Heather stepped closer to Callie, her scent hitting Callie like a punch in the gut. She smelled sweet and inviting, her omega pheromones tempting Callie's alpha instincts to take over.
"I've been admiring you from afar for a while now, Dr. Torres. And I can sense that you're in heat, but I can help you. Please, let me help you," Heather said, her voice soft and alluring.
Callie's eyes widened in shock. Sure she had been propositioned like this before, especially by omegas. But ever since she had mated with Arizona, Callie had not felt the urge to mate with anyone else. But the way Heather was looking at her, with those big brown eyes and plump lips, made Callie's resolve weaken.
"I-I can't," Callie stammered, taking a step back. "It's against…. I'm not interested."
But Heather was insistent, and before Callie could protest further, she sank to her knees in front of Callie. Callie felt her body respond to the omega's proximity, her scent overwhelming her senses. She tried to resist, but when Heather reached up and began to undo Callie's pants, she couldn't help but give in to her primal desires.
Callie's 8-inch cock sprang free from her pants, fully erect and throbbing with need. Heather licked her lips, her eyes fixed on the pulsating member in front of her. She took it in her hands, marvelling at the size and girth of it.
"It's beautiful," Heather said, her voice husky with desire. Her pale hands were too small to grasp the thick dick fully.
Heather stood up, still stroking Callie's length. With a wicked gleam in her eyes, Heather looked up at Callie, a hint of a smirk on her lips. "I can tell you want this, Dr. Torres. Don't fight it."
Callie felt a surge of arousal in her body at the omega's words. She tried to resist, but it was no use. Her alpha instincts were too strong, and the last week of her heat had left her desperate for release.
Heather leaned in and pressed her lips to Callie's, her tongue tracing along the alpha's lower lip. Callie moaned, unable to resist any longer. She grabbed Heather's head and deepened the kiss, her tongue duelling with the omega's.
The two women pulled away from each other, gasping for breath. Callie's hands reluctantly roamed down Heather's body, feeling the curves of her hips and the softness of her breasts through her scrubs.
"You sure about this? This can't mean anything more…," Callie whispered, her eyes drinking in the sight of the omega before her.
Heather smiled, a hint of mischief in her eyes. "I'm sure Dr. Torres. I have heard a lot of stories about you and I won't mind a sleazy side affair with you. Shhhh no one will no about us…..But I think it's time we got rid of these clothes, don't you?"
Callie nodded, and the two women quickly shed their scrubs and underwear, leaving them completely naked.
Heather sank to her knees once again, her eyes fixed on Callie's pulsing cock. She ran her hands up and down Callie's thighs, teasingly avoiding the alpha's erection.
"Please," Callie moaned, her hips bucking forward in an attempt to get closer to the omega's mouth. Her hard length slapping on Heather's cheek, desperate to enter her mouth.
Callie groaned, her head falling back in pleasure. She had been on edge all this week and now her alpha instincts are taking over completely. Heather began to stroke her cock, her fingers expertly massaging the sensitive tip. Callie's hips bucked, pushing her cock further into Heather's hands.
"Fuck," Callie moaned, her hands gripping Heather's bob of hair.
Heather took that as her cue to take Callie's cock into her mouth, sucking it deeply into her throat. Callie's eyes rolled back in ecstasy, her hips thrusting rhythmically into Heather's mouth. She felt herself getting closer and closer to the edge, her balls tightening with the impending release.
Heather chuckled. She swirled her tongue around the head, then took as much of the shaft as she could in her mouth, bobbing her head up and down.
Callie's hands tangled in Heather's hair as she thrust her hips forward, unable to hold back any longer.
As Heather pleasured Callie with her mouth, the alpha felt her restraint slipping away. Her body was craving release, and the omega nurse was more than willing to give it to her.
"Oh, fuck," Callie moaned, her hands finding their way to Heather's hair again. She guided the omega's head, urging her to take more of her length.
Heather was eager to please, taking Callie deeper and deeper until the alpha felt her climax building. With a shuddering gasp, she came hard, her release coating Heather's tongue.
For a moment, Callie was lost in the bliss of her orgasm. But then reality came crashing down around her. What had she just done? She felt like she had just cheated on Arizona, the one person who was starting to mean so much to her. They were not official but Callie still felt guilty.
"Shit," Callie muttered, pulling away from Heather. "What the fuck did we just do?"
Heather looked up at her, her lips swollen and glistening with Callie's arousal. "You needed release," she said softly. "I wanted to give it to you."
"But I'm bonded," Callie said, her mind racing. "I'm bonded to Arizona. This shouldn't have happened."
Heather shrugged. "Sometimes, even the strongest bonds can't hold back the heat," she said. "It's just biology, Dr. Torres. You can't fight it."
Callie knew that Heather was right. But that didn't make it any easier to accept. She really liked what Arizona and she had created in just few days more than anything, and the thought of betraying her like this made her feel sick.
"I have to tell her," Callie said, her voice barely above a whisper.
Heather nodded sympathetically. "I understand," she said. "But be prepared for the consequences."
Callie knew that Heather was right. There was no way to predict how Arizona would react to the news. But she knew at some point she had to tell her the truth.
"I have to go," Callie said, going away from Heather and quickly getting dressed.
Heather looked at her with disappointment in her eyes. "Will I see you again?"
Callie hesitated for a moment before nodding. "Yes. But we can't do this again. It's not right."
Heather nodded, a sad smile on her lips. "I understand. But I can't help how I feel about you, Dr. Torres."
Callie gave her a small smile before turning and walking out of her office.
As she made her way home, her mind was filled with thoughts of Arizona. She knew she was in dangerous territory, and she will have to make things right.
The next day, Callie prepared herself to come clean with Arizona. Now that she had got time to sleep on it, she didn't feel ashamed anymore. She was in heat and her primal urges led her to seek relief. She had behaved as any alpha would do. It's not uncommon for alphas to have multiple partners. Callie reasoned with herself. Lost in thought, she entered the elevator with a bunch of other hospital staff, Callie felt confident about herself. Heather was nice, no good as Arizona but the blonde tramp knew how to use her mouth. Callie smirked.
As the elevator emptied itself, Callie was still leaning against the far wall, lost in thought- to an extent that she didn't notice Heather entering and the elevator closing behind her.
"Dr Torres!" Heather purred, pulling Callie out of her thoughts, "I hope you slept peacefully last night!" she smirked.
Callie looked up at Heather, the previous night's images flooding back to her mind.
"It's so hot in here", Heather said as she opened the first three buttons on her nurse uniform and walked towards Callie slowly.
As Heather approached Callie, she couldn't help but notice how the nurse's ample cleavage was bursting out of her uniform. Heather leaned in, pressing her chest against Callie's, and began to stroke the alpha's length through her pants.
Callie held her hands, and pushed it away "We are done Heather" she growled
"Please, Callie, just this once," Heather whispered, her breath hot against Callie's ear. "I can make you feel so good."
Callie tried to resist, but her body was already responding to Heather's touch. She closed her eyes and let out a low growl as Heather's hand moved faster, her fingers dancing over Callie's hard length through her scrub pants.
"You know you want this, Callie," Heather purred. "You want to let go and lose yourself in the pleasure."
Before Callie could even think to respond, Heather sank to her knees and began to undo Callie's pants. The alpha's eyes flew open in shock, but it was too late. Heather's mouth was already closing around her, sucking and licking with wild abandon.
Callie gasped and clutched at Heather's hair, her hips bucking uncontrollably as the nurse worked her over. She could feel her release building, and she knew it was going to be a powerful one.
But just as she was about to let go, the elevator dinged and the doors opened to reveal Arizona, standing there in shock.
"Callie? What the hell is going on?" Arizona demanded, her eyes flicking between Callie and Heather.
Callie tried to speak, to explain what was happening, but all that came out was a low growl as she came hard, her body shaking with the force of her orgasm.
Heather drank all of Callie's release and then stood up, a smug grin on her face as she looked between Callie and Arizona.
"Well, that was certainly a surprise," Heather said. "But don't worry, Dr. Robbins. I'm sure we can find a way to make it up to you."
Arizona's eyes widened, and she took a step back, clearly unsure of what to do next. Callie felt a wave of shame wash over her as she realised what she had just done. She had given in to her desires, and now it was all going to blow up in her face.
Later that night, Callie knocked on Arizona's apartment door, her heart pounding in her chest. She took a deep breath and composed herself before Arizona opened the door.
"What the hell are you doing here," Arizona said, looking surprised to see her.
"I wanted to apologise," Callie said. "For what happened at the hospital. I know I shouldn't have given in to Heather's advances, and I'm sorry."
Arizona's expression hardened, the atmosphere quickly turned tense.
"Arizona, about what you saw in the elevator," Callie started.
"I don't want to talk about that," Arizona interrupted. "It's not like I haven't heard things like that about you before. Everyone know you are the hospital slut"
Callie's heart sank. She knew where this was going.
"I'm an Alpha, Arizona," she said, trying to keep her voice calm. "We don't do monogamy, especially not during heat."
Arizona felt angry and betrayed. Callie wasn't even sorry about what she did, "That doesn't mean I have to be okay with it. I'm not sure I want to be with someone who isn't monogamous." she shot back as she turned around and walked inside the apartment, Callie hot on her trail.
Callie took a deep breath, trying to control her emotions. "But we have something special, Arizona," she said. "Don't let this ruin what we have."
Arizona looked at her with a mix of anger and frustration. "You can't be serious, Callie," she said."You screwed someone else after we mated. After you put your mating mark on me and bonded with me and now you don't care about monogamy but want me to continue whatever the fuck we had? It was just sex Callie."
As Callie tried to explain herself again, Arizona cut her off. "You know what, Callie? I can't believe you. You say you care about me, but then you go and sleep with someone else while I'm stuck in surgery. And you expect me to just forgive you?"
Callie's jaw tightened as she felt her own anger rising. "I never said it was okay, Arizona. But you know how it is during heat. It's not easy to control your urges."
"And what about after heat? Are you just going to go back to sleeping with anyone you want? Is that what our mating means to you?"
Callie took a step closer, her voice low and intense. "Alpha's don't do monogamy, Arizona. Not especially during heat. I don't explain how heat works to you Arizona."
Arizona's eyes flashed with hurt and anger. "Alright, so will you be okay if I fucked someone else during my heat?"
Callie growled, an animalistic sound escaping her lips, but then she restrained herself. Anger won't take her anywhere.
"We are different, Arizona. Alphas and Betas & Omegas are very, very different" Callie added. "I can't suddenly change who I am, Arizona"
Arizona shook her head, her voice thick with tears. "I don't know if I can be with someone who isn't monogamous, Callie. It's just not something I'm comfortable with."
Callie sighed, running a hand through her hair. "I understand that, Arizona. And I don't want to lose you. But I can't pretend to be someone I'm not."
Arizona nodded furiously, her expression pained with anger. "I need some time to think, Callie. I can't make any decisions right now."
"Take all the time you need," Callie said softly. "I'll be here when you're ready."
Callie's heart was heavy as she left Arizona's apartment. She knew she couldn't change who she was, but she didn't want to lose Arizona either. She had a lot to think about.
