Jace had Aurora bent over the edge of the massive bed, her body pressed flat against the white sheets with her face turned sideways and her mouth open in a silent cry. His hand wrapped around her throat from behind, tilting her head forward with his fingers spread along her jaw. His other hand gripped her hip hard enough that Addison could see the indent his fingers made in Aurora’s skin. His body covered hers completely, broad shoulders blocking most of Addison’s view, but she could see enough.

Aurora’s breasts hung down beneath her, swaying with each brutal thrust, and white liquid dripped from her nipples onto the sheets in thin streams.

Milk.

Aurora was lactating. Actually producing milk while Jace fucked her from behind with the kind of raw intensity that made Addison’s thighs clench together reflexively.

Aurora’s voice came out strangled and desperate. "Jace, I’m so close."

"I know." His voice sounded rough, strained, nothing like the polite freshman from dinner. "Come for me."

He drove into her harder, his hand tightening slightly around her throat while his hips slammed against her ass with meaty sounds that should’ve been obscene but weren’t. Aurora’s entire body shook, her fingers gripping the sheets like they were the only thing keeping her tethered to reality.

Addison couldn’t breathe.

She stood frozen in the hallway, her back pressed against the wall beside the door, heart trying to punch through her sternum. Her face felt nuclear hot. Her pussy throbbed with each pulse of blood through her body.

This was wrong. She shouldn’t be watching. This violated every boundary of friendship and decency.

But she couldn’t look away.

Aurora came with a scream that probably violated noise ordinances in three counties. Her back arched impossibly, head thrown back against Jace’s shoulder while her whole body seized. More milk sprayed from her nipples, splattering the expensive sheets in white patterns.

Jace kept moving through her orgasm, riding it out, his own breathing ragged now. His grip on her throat loosened but stayed present, keeping Aurora’s head tilted at that vulnerable angle.

"Again," he said. Not a question.

He pulled out suddenly, flipped her onto her back with surprising strength, and drove back into her before she finished protesting. Aurora’s legs came up around his waist automatically, her heels digging into his lower back.

Jace’s mouth found her right breast and sealed around the nipple. He drank, his throat working visibly while he thrust into her.

Addison’s hand moved without permission. Slid down her stomach. Bunched her dress up around her hips. Pressed against the soaked fabric of her black lace panties.

This was insane. Completely deranged behavior.

But her fingers found the seam and slipped underneath anyway, finding herself wet and ready and aching.

In the bedroom, Aurora’s hands tangled in Jace’s hair, pulling him tighter against her breast while her hips rose to meet each thrust. "It’s so good, why is it so good?"

Jace lifted his head, milk glistening on his lips. "Because I’m making you mine."

"Cocky."

"Accurate." He drove deep and held there, grinding against her. "Tell me whose you are."

"Yours." Aurora’s voice cracked on the word. "Fuck, I’m yours, just don’t stop."

Addison circled her clit slowly, biting down on her free hand to keep from making sounds. Her legs trembled. Her vision blurred at the edges.

She watched Jace bend down and kiss Aurora properly, his tongue sliding into her mouth while he kept moving inside her. Aurora kissed back desperately, her body responding with these perfect little rolls of her hips that matched his rhythm exactly.

They looked good together. Natural. Like they’d been doing this for years instead of weeks.

Addison’s fingers moved faster now, her breathing coming short and sharp through her nose. She pressed harder against herself, chasing the building pressure that made her abdomen tighten and her toes curl against the carpet.

In the bedroom, Jace pulled back from the kiss and switched to Aurora’s left breast, drinking greedily while Aurora writhed beneath him. Her voice had gone high and thready, words dissolving into these gorgeous broken sounds that made Addison’s entire body clench.

"I’m going to come again," Aurora gasped. "Jace, I’m—"

"Do it." He bit down gently on her nipple, still buried deep inside her. "Let me feel it."

Aurora came apart completely. Her spine bowed off the mattress, her mouth open in a silent scream, her pussy visibly contracting around him in rhythmic pulses that Addison could see from the doorway.

The sight pushed Addison over her own edge.

She came standing against the hallway wall with two fingers pressed hard against her clit and her teeth sunk into her palm to muffle the sound. Pleasure rolled through her in waves that made her knees buckle. She caught herself on the wall, breathing through her nose while her body shook through the aftershocks.

Inside the bedroom, Jace groaned low and finished, his hips jerking forward twice before he went still. Aurora’s legs tightened around him, holding him deep while he came inside her.

Addison straightened up slowly, her hand still between her legs and her face burning with shame and residual arousal. She’d just masturbated to her best friend having sex. That was a new low even by her standards.

Jace rolled off Aurora and collapsed beside her on the bed, both of them breathing like they’d run marathons. Aurora turned her head and said something too quiet for Addison to hear. Jace laughed, the sound warm and genuine.

Addison backed away from the door on silent feet, grabbed her purse from the kitchen counter, and fled to the couch.

What the fuck was wrong with her?

She stripped off her dress and collapsed onto the pull out bed in just her bra and panties, staring at the ceiling while her brain refused to cooperate with anything resembling rational thought.

She’d just watched Jace Monroe—lottery kid, milk vampire apparently, Aurora’s new obsession—dominate her best friend so thoroughly that Aurora literally begged him not to stop. And instead of feeling protective or concerned or disgusted, Addison’s primary emotion was jealousy.

Not jealousy that Aurora had found someone. Addison was genuinely happy about that part.

No, she was jealous because she wanted that for herself. Wanted someone who looked at her with those amber eyes and made her feel like the only person in the room. Someone who could handle her intensity and match her aggression and make her submit without making her feel weak.

Someone like Jace fucking Monroe.
