A/N: Hi guys, I'm so sorry but yes this story has infidelity. It's not nice, it's not desirable but it's life and it's Callie cheating with Arizona and not on Arizona so I hope you don't mind too much :)

Stop making the eyes at me, I'll stop making my eyes at you. What it is that surprises me is that I don't really want you to - Arctic Monkeys

The first time it happened Arizona Robbins had not expected it at all. After the night with dinner at Callie's the two had seemed to gone on with their lives as usual. Arizona blushed bright red every time she remembered what had happened over dinner and Callie, well Arizona knew that Callie had a lot on her plate - with school work and Mark and all. In a place like Harvard, sure you easily ran into someone, but in a way it was also very much possible to avoid a person you wanted to. Arizona wasn't sure what exactly Calliope wanted with her, and she didn't want herself mixed up. Until Calliope made up her mind, Arizona was willing to wait. She had waited a year, she could wait longer.

Addison Montgomery, meanwhile, had become a very close... uhm... acquaintance of Arizona's. The two weren't sleeping together too much. They hadn't labeled what they were doing. They were certainly friends, friends with benefits would suit it but maybe not. They'd hang out a lot - go to the movies, grab more pizzas, get to know each other. Arizona wasn't deeply infatuated with Addison, but she liked her. If she wasn't going to be the one and only for Calliope, who ever said that Calliope had to be the same for her? She was so much stronger now, she had learnt to be on her own two feet. She had learnt to live her college life not necessarily getting whatever or whoever she wanted and she was good with that.

The first time it happened was a Friday night, two weeks later. Addison had just left Arizona's after a session of The Voice marathon - she had a midterm on Tuesday and she left early to study. April was away with Jackson as usual. God, Arizona really felt like she had a single room most of the time, rather than having a roommate. Arizona was cleaning her room when she heard a knock on her door. She thought it was probably Addison so she casually opened the door.

Except it wasn't Addison.

It was fucking Calliope Torres.

Calliope Torres, who, when Arizona opened the door, smiled at Arizona and mumbled a "hi" as Arizona invited her in. Calliope Torres who locked the door the minute Arizona closed it. Calliope Torres who grabbed Arizona by the collar of her shirt and gently pushed Arizona onto her own bed, falling on top of Arizona as she fell.

"What the-" Arizona asked, surprised.

The brown - goddamn beautiful brown - eyes met the blue and Arizona could see it in Calliope's eyes. It was full of desire, full of need, Arizona knew how to read most females by now and the lust she saw in Calliope's eyes was no mistake.

Then it happened. Arizona felt Calliope's lips crash against her as she was pushed further into the bed. Soon Arizona felt Calliope's tongue make its way into her mouth as she devoured the taste. Arizona kissed Calliope back.

This was it.

Calliope was in her room, Calliope was kissing her, but something wasn't right. But Arizona couldn't find the strength, the energy or the urge to complain. Because by then Calliope had unbuttoned all of Arizona's shirt and unzipped Arizona's jeans. Arizona knew better than to question this and took Calliope's t-shirt off and unhooked the Latina's bra. She kissed the Latina's neck, and she could have given anything to hear the moan that escaped the brunette's throat one thousand times more. And she did.

"What just happened?" Arizona asked, finally as she lay next to Calliope, both of them worn out and extremely tired - but satisfied, on the bed.

"I wanted you," Calliope said, sighing. "I needed you. I... I don't know... I just..."

"You just always get what you want," Arizona said, still disbelieving of what had just happened between her and the Latina of her dreams. "Don't you princess?"

"Why are you being so sarcastic?" Calliope asked. "Not like you weren't enjoying it."

"See Calliope," Arizona said. "There's a difference. You can't just have whatever you want whenever you want it. It's not how life works. See you think you can just come here escape from all your princess drama and your weird shit and your boyfriend and his admirers. You have to go back at some point."

Calliope turned on her side and faced Arizona. She stroked the blonde's cheek and Arizona could feel the electricity. As much as she didn't want to admit it, she really did like the Latina.

"I'm sorry Arizona," Calliope said, almost in a whisper. "I know. I know I keep trying to escape from it. I know I shouldn't - I know I shouldn't be dragging you into this but- but I don't know something's been happening -"

"What do you mean Calliope?"

"I've-" Callie said, sighing. "Since the day with the math and the dinner the next day - I've been thinking so much about you. I just feel like- I feel like you could make me happy."

"Calliope," Arizona said. "Look, I feel things for you too, but I can't get in the way of you and your boyfriend and last week and today and now - I- I have and I feel terrible-"

"You shouldn't," Callie said. "I like you and I like - I like this between us. Mark and I - we don't have this. We don't talk. We barely meet these days. Last year he was so much nicer. This year - he's such a jerk, he just brings me to show off at parties and fucks me whenever he feels like it. But I have to be with him, because, because he's Mark and I'm Callie and certain things have to stay the way they are. And with you, with you I feel special, with you I feel, I feel wanted."

"But Calliope," Arizona said, pleading. "I can't do this. You can't be with him and come to me and-" "Arizona," Callie said, brown eyes looking at the blue with affection.

"Not all the time, but sometimes. Please."
