A/N; someone wanted dratomione a/b/o and i really want more of it too

She'd read about the phenomenon in a book, but, she'd brushed off the notion as absurd and unrealistic. Alpha's were incredibly territorial of their omega's and she'd seen for herself how even friendships had ceased to exist between two members of the opposite sex once one of them had bonded with their alpha. so she was under no illusion that it would end well, for any of those involved, if an omega had two alpha's..

Except of course when she met them, and everything she thought she knew about herself went out the window.

Both her best friends in school had been alpha's, though Harry wasn't as well built as Ron, his glare alone, had kept plenty of lecherous alpha's away from her. But then she'd gone to hogwarts university - 500 miles in the opposite direction to them and well.

She'd walked into her first class, hair pulled high up into a ponytail, wearing her favourite pair of jeans and converse with a ratty old sweater and thought nothing of the intense smell of chocolate that immediately clouded her senses, especially since she'd seen her new lecturer, Professor Lupin, practically devour a bar of the stuff at orientation.

She blamed the sudden headache on the bright lights and shifted in her stool to avoid the glare.

She blamed her clumsiness when she stood at the end of class on her weak ankles.

She blamed the blush she felt searing across her face on the embarassment of stumbling and most decisively not on the way the two men she'd squeezed past at the beginning of the class were leering at her.

"That's her."

Tom looked up from the ground and glared at his best friend - the first and only person he'd ever let into his life and knew that it had been inevitable.

Of course the fates had decided they would share this too. He uncurled his fist.

"I know."

"After class?" Draco asked, though he wasn't looking at him - his eyes were unabashedly following the girl - Tom didn't blame him.

Those fucking jeans.

"Yeah," he grunted, dragging his eyes back to the front of the lecture hall, "after class."

She didn't even remember how they'd ended up back at their apartment. One minute she'd been standing at the top of the stairs looking at them and the next they'd been pursuing her down the crowded corridor and pulling her into an empty classroom.

As soon as they'd touched her, she fell into sub-space quicker than any o her own orgasms had made her and practically melted in their arms.

"Jesus fucking Christ Draco," the dark haired one muttered as he watched his friend slip his hand under her jumper, "we can't do this here."

"I just want to….fuck-" he broke off tearing himself away from her and taking a harsh breath through his mouth, "let's take her home Tom."

"We don't even know her name arsehole," Tom grit out between his teeth, even as he rubbed his erection against her backside.

"Her- Hermione," she murmured, shaking herself and bending her neck to look up at him, "my name's Hermione."

Tom's nostril's flared and his tongue glided along the front of his teeth, his perfectly straight, white , oh my parents are going to love him, teeth.

"Herm-"

"You're my alpha." She felt his dick twitch and press harder against her and regretted her decision to not wear a dress before she flashed her eyes in the others, Draco's, direction, "You're both my alpha."

Draco took two steps forward and gripped her hip harshly as he thrust his erection against her crotch, "and you're ours, omega," he breathed against her ear, the sound destroying any hope she had of salvaging her knickers.

"Home now," Tom whispered harshly against her neck as he nipped her pulse point with his teeth.

She shuddered in their arms.
