So, I haven't written something SQ in a while (lol, lies) and when this idea hit me, I decided to make it a two-shot story :)

I know what Emma does in this chapter is not allowed in many countries, but it is allowed in mine. A med student can enter into an OR if the surgeon is responsable for the student.

Thank you, Sam, for correcting the typos and making it better!

Part 1/2

Emma Swan remembered perfectly the first time she had met Dr. Regina Mills. It had been four years ago, when Emma was nothing but a med student and Regina was the resident anesthesiologist, fresh out of specialization.

Emma was in holidays, and her father thought it would be good for the future doctor to gain experience by his side. And so, Emma Swan ended up walking into the OR, already dressed for surgery, next to her father.

Inside her father's OR there was already another doctor, she was talking to the patient, a pregnant lady, explaining the procedure she would do. By Emma's basic level of knowledge, she could deduce the other doctor was an anesthesiologist.

"Dr. Mills, this is my daughter, Emma Swan," her father introduced her to the doctor.

At the mention of her name, the anesthesiologist raised her gaze for the patient to father and daughter. She was also completely dressed, and everything Emma could really see were the doctor's eyes. For any ordinary person, they would have been plain brown eyes, but for Emma they were a pool of dark chocolate and coffee, her two favorite things, so inviting.

"Emma," David interrupted his daughter's trance, "This is Regina Mills, the latest addition to our surgical team," he said and Emma didn't know who made his father prouder, Regina or herself.

"Nice to meet you," Emma muttered, still half lost in Regina's eyes.

"Likewise," she replied, but her gaze was already back in the patient.

As soon as the patient was asleep David and Whale, another obstetrician, started the c-section. The two doctors would explain everything that occurred during pregnancy to Emma as they performed different procedures while the student pretended to pay attention, when she was really stealing quick glares towards the anesthesiologist's corner.

"Pregnancy should be defined as pathology," Emma thought out loud, and almost slapped herself when everyone turned to look at her, even Regina "It ends with a wonderful thing, yes; but you can't tell me all this pain and all this is normal," she tried to explain her thoughts waving her hand over the open abdomen.

Surprisingly, it was Regina who answered to Emma.

"That's how you know the term was defined by a man," she said "It should be defined as a reaction to a foreign body"

Whale gave so statements to refuse Regina's opinions, but the women had their mind made about the topic. When Whale gave up on arguing with Regina, they went back to the obstetricians explaining things to Emma, and both women staying quiet.

As an addict who is deprived from their drug, Emma kept on looking at the place where Regina was sitting, checking on the patient's vital signs. Every once in a while, Regina would look up and stare into Emma's eyes, then she would go back to the patient's vital signs. Each time, Emma would find herself more and more drawn into the brunette's eyes; and each time, Regina would get more annoyed and uncomfortable by it.

When the baby was delivered and the mother's stomach was sutured, David told Emma to go and change into normal clothes so they could go and have lunch. Emma looked one last time towards the chair where Regina, who now was talking to the newly mother, had been sitting and walked out of the OR and towards the changing room

Thankfully, Emma found the changing room empty, she really didn't really feel like talking with her father's colleages. Nor her mother's, who was also a doctor working at this clinic. Emma took of the mask and scrubs and threw them away, then she prodeced to change into normal clothes. She was taking her shirt off when someone stormed into the room and pushed her against the lockers, it was Dr. Mills.

Regina was not longer wearing the mask and Emma could finally see Regina's lips, they were perfect, with the exception of the little scar above her lips; but it didn't make Regina less attractive, it made her real and interesting. Emma gulped, the contact of her bare abdomen against Regina's fingers, which held her against the lockers, made it hard for her to concentrate on whatever Regina was going to complain about.

"Stop looking at me like that!" Regina growled "You make me want to cheat on my husband,"

"I can't," Emma snapped back, she was not the one to stay quiet.

"Why?" The question was accompanied by Regina tightening her fingers around Emma's sides, probably hurting the blonde - or turning her on.

"Because you make me want to cheat on my boyfriend too," Regina seemed taken aback with the answer, because she let got of Emma and fixed one of her brown locks of hair behind her ear.

Emma took the doctor's silence as an invitation to invade her personal space, so she took one step forward. Now, Regina was almost pressed against the mirror; the brunette didn't back off or look away, she kept on staring into Emma's eyes, noticing how the blonde's eyes shifted between her lips and her eyes, almost as a seductive dance.

"Mills," Emma let a whisper out, it was filled with lust and it turned Regina on, no one had ever said her last-named with so much passion.

'She's leaning in,' Regina thought as she saw the blonde getting dangerously close to her 'she's actually going to kiss me!'. And then the thrill of doing something forbidden became guilt and panic started to build inside her chest. And Regina took a step back.

"I'm sorry," Regina said, pressing her hand against Emma's shoulder to keep the other woman at a decent distance and then ran away as if her pants were on fire.

Emma looked at the door that had closed after Regina left. 'What was she sorry for?'
