A sliver of moonlight spilled into the room from the bedroom window as Spencer stood in front of you, his hazel eyes searching yours in the darkness. His bare chest rose and fell slowly as you both stood facing each other, your hearts beating as one. He let out a quietened breath, a smile tugging on your lips as you eagerly bounced back and forth on your heels, waiting for his command.

"Do you trust me?"

His voice was soft and full of care as he reached behind his back, his eyes never once leaving yours.

You nodded at him. "Always."

He nodded back at you before pulling his hands out from behind his back, the metal from the edged instrument between his fingers glimmering in the moonlight peering in from the bedroom window. Your eyes widened as you looked at the knife, your heart starting to race.

"You know I would never hurt you," Spencer's voice was quiet, and you looked at him, recognizing the concern laying beneath his eyes, "right?"

You gulped, nodding at him. "I- I do."

"Good."

He brought the knife to your face, moving the blunt edge of the blade across your cheek. You gasped, your heart thundering inside your chest. Your eyes were locked on Spencer's as he brought the knife beneath your chin, tilting your head back. "You're so beautiful like this," he whispered, pushing the tip gently into your skin, a staggered whimper rushing past your lips.

Spencer dragged the knife down your neck, careful not to cut you as you leaned your head back, clenching your fists and biting your lip, trying not to fucking move. Spencer brought the knife to the tops of your breasts, looking at you before he pulled the blade downwards in one quick slice, cutting open your shirt. You gasped at the sudden, swift movement, Spencer's hand moving to cup your cheek as he whispered, "Shh," bringing his lips beside your ear, his warm breath sending shivers down your spine. "You're okay."

Ecstasy pulsed through your veins as he slipped the torn shirt off your shoulders, bringing the knife to the dip in your neck. Spencer's other hand moved to your throat, wrapping his fingers around it as he pulled you into him, pressing his lips softly to yours.

He dragged the flat edge of knife down your body, a soft whimper from you slipping into the kiss as the cool metal of the blade burned against your skin, tingling where it touched you. The knife slipped into your bra, cutting away the clasp. Spencer pulled the article of clothing off of you, the hand around your throat moving to cup your breast.

His fingers pulled at your nipple, your eyes falling shut in pure, blinding pleasure as Spencer drew the cutlass down your body, his lips moving with yours as he pushed the tip into your skin, pricking you. Gasping, you pulled away from him, your eyes flicking down to your stomach as a bubble of blood formed at the surface.

"You okay?"

You looked up at Spencer, his eyes searching yours for any hint of fear or of resistance, but you nodded your head, and he smiled at you. "Good."

He pushed you back on the bed, walking over to his closet, returning moments later with the same black nylon rope he'd used on you your first time together. Moving higher up on the bed, you willingly held your wrists out to him, his hands gripping your wrists as he carefully tied them to the headboard. Spencer climbed onto the bed, throwing his leg over you as he reached down, pulling your panties down. He crawled down your body, his eyes locked on yours as he planted a soft kiss on your stomach, grabbing your ankles and tying them to the footboard, his thumb moving in gentle circles over your skin.

Spencer brought his hand to your entrance, dragging his fingers up your wet slit and you groaned, pulling on the ropes. "Mm," he chuckled, smirking at you. "You're so wet for me."

He moved his thumb to your clit, rubbing it in circular motions as he put the blade away, your back arching as you moaned, grinding your hips into his hand.

Spencer pushed a finger into you, curling it inside you and you gasped, wriggling against the bedsheets. The bulge in his pants grew as he watched you, your lips parting and moaning as he pushed another finger into you, pumping and curling them inside you. "F- Fuck," you whined, feeling him hit your sweet spot, your eyes falling shut.

He increased the pressure on your clit, moving it in time with each curl and thrust of his fingers, your pussy clenching around them. Spencer groaned at the sudden tightness around his fingers, curling them as he hit your g-spot, his tongue poking out of the corner of his mouth. The knot in your stomach began to tighten as you pushed your head to the side, groaning at the feeling of his long fingers pushing into you.

"Are you gonna come?" Spencer asked, increasing his pace, a loud moan leaving you.

"Fuck," you whined, opening your eyes as you looked at Spencer, his hand moving to palm the bulge in his pants. He groaned, curling his fingers inside you, watching you as you came undone at his very hands.

He took your groan for an answer, retracting his fingers from inside you as he smirked at you, ignoring the loud groan of frustration you gave him. "Not yet," he told you. He moved up on the bed, looking down at you as he brought his hand in front of your face, whispering, "Open." You obliged, parting your lips as he pushed his fingers into your mouth, groaning as you sucked on them, swirling your tongue around them.

Spencer pulled his fingers out of your mouth, climbing off of you as you whimpered, your pussy clenching around nothing as you pulled at the ropes binding you to the bed. Spencer pulled open a drawer in his bedside table, reaching in and pulling out the navy blue satin blindfold, holding it up in front of your face, showing it to you. "Is this okay?" He asked, and you nodded, lifting your head as he tied the blindfold around your eyes, blocking your vision.

Your heart pounded inside your chest, your breathing growing heavy as you heard Spencer's footsteps circling the bed, hearing the scrape of metal against the bed frame. You gasped, tugging at the ropes.

The dull edge of the knife moved down your body, your skin igniting at the contact as you bit down on your lip, holding back a whine. Spencer dragged the blade over your thighs, his lips beside your ear as he whispered, "You're being such a good girl."

You whimpered at his praise, the knife moving to your breasts, a gasp leaving you as Spencer dragged the edgeless curve of the blade between your breasts, wriggling in the ropes. "Try not to move," he whispered in your ear, placing his hand over your stomach. "I don't wanna hurt you."

The caution in his words made you relax, your chin jutting up to the ceiling as he moved the knife over your collarbone, your skin burning beneath its touch. A moan rushed past your lips as the blade dragged down your stomach, moving to where he'd already pricked you. He teased the sensitive skin, a soft cry rolling off your tongue as you fought the urge to squirm, fire coursing through your veins.

Spencer moaned beside you, the sharp contact from the blade leaving you as you heard a clink of metal against wood beside your ear. Spencer grabbed your wrists, unbinding them and your ankles before he pulled the blindfold off, your eyes meeting his as he looked at you, his face in a state of duress. "You were such a good girl," he said, gripping your hips.

He whipped you around, pulling your hips up as he fiddled with his belt, kicking his pants and boxers off. Spencer's hand wrapped around his dick, pumping it a few times before slamming into you, your hands twisting in the bedsheets as you cried out, Spencer groaning behind you. "Fuck," he moaned, pushing himself deeper inside you before he snapped his hips forward, bottoming out inside you.

Burying your face into the bedsheets, you brought your hand down to your clit, rubbing it as Spencer thrusted into you, pulling your hips back against him. "Fuck— that's right. Take my dick," he groaned to you, angling his hips to thrust deeper inside of you, feeling your orgasm already starting to build from him finger fucking you.

His hand wrapped around your throat, pulling you up as he applied pressure to your neck, a gasp catching in your throat as you held yourself up on your hand for support, increasing your pace on your clit. Spencer's fingers squeezed your throat as he fucked you from behind, his dick twitching inside of you.

The knot in your stomach started to unwind as you grew lightheaded, pushing your hips back against Spencer's as he moaned behind you, his nails digging into your skin. Gasping, you reached up, tapping your finger against his hand and he pulled it away, gripping your hips as he continued to thrust deep inside you, your walls clenching around his dick.

Then you cried out, your legs shaking as you came, pushing your head into the mattress as the feeling of sweet release washed over you, a string of moans flying past your lips. After a few more sloppy thrusts, Spencer buried himself deep inside you, groaning as he shot his cum into you, his nails digging into your skin so harshly it was wonder to you how your skin didn't break. He pulled out of you, falling down beside you on the bed as he panted, pushing a hand through his sweaty curls.

"Oh, fuck," he groaned, looking over at you as you fell forward on your stomach, panting. He smiled at you, placing his hand over your back as he laughed. "I don't know how I could ever grow tired of you," he said, his eyes flicking to yours.

"Even when I'm a brat?" You asked, smiling at him.

He reached down, giving your ass a gentle slap as he shook his head at you. "Every other time," he said, "except for when you're being a brat."

Spencer sat up, grabbing you by the wrist as he said, "Come on." He let you pee and wash your hands before he came into the bathroom, zipping his pants up. He handed you your panties, waiting for you to pull them on before he opened his bathroom cabinet, grabbing a bandage. He pulled it open, smoothing it over the small prick from the knife before he handed you one of his T-shirts, you slipping it on over your shoulders.

Spencer led you into the bedroom, pushing you down on the bed as he laughed, moving around to his side. You eagerly scooted closer to him as he laid down beside you, happily excepting his warm embrace as he pulled you into him, pushing his fingers through your hair. "Get some sleep, darling," he whispered, you giggling as you closed your eyes, curling up in his arms as you drifted off to sleep.

The first thing that registered in your mind when you woke up the next morning was Spencer gripping your wrist, hearing him groan beside your ear as your ringtone blared loudly throughout the room. "Get it," he grumbled to you, and you giggled, watching him roll over to his side, pushing his head into the pillows. You grabbed your phone, noticing it was Hotch calling you, and you answered it.

"Really? At 6:30 in the morning?" You asked, yawning.

"Crime never sleeps," Hotch said to you. "I need you here at the BAU. An urgent case just came in we need to review. I'll have Garcia call the rest of the team."

As you hung up on him, you looked over at Spencer in the bed beside you, a smile forming on your lips. You reached out, combing your fingers through his hair as he groaned, flipping over to look at you. "It's a case, isn't it?" He asked, his eyes only opening halfway as he looked at you, yawning.

"It's always a case," you giggled.

As if on cue, Spencer's phone rang, and he let out a load groan, reaching for his phone on the nightstand. You giggled as you listened to him talk to Garcia, his voice rasping with exhaustion at each word he spoke, something you wondered if you should find attractive as much as you did. You climbed out of bed, going over to your go-bag in the corner and pulling out a change of clothes, going into the bathroom to change.

Spencer walked in a few minutes later, pushing his hand through his curls as he stumbled past you, rubbing his eyes groggily. You laughed and he shot you a look before he bent over the counter, splashing his face with water. "Oh, you are so not a morning person," you giggled to him.

"I stand by the philosophy that anyone who is a morning person is mentally insane," he grumbled, patting his face dry with a towel.

"Come on, little boy," you snickered, walking over to him and smacking your hand against his ass, hearing him gasp. "If you get dressed fast enough, I'll pay for coffee on the way."

"I'm gonna act like you didn't just do that because I want coffee and we have to get to work," Spencer said, looking at you, "but otherwise the whip would become your new best friend."

"There was a mass murder in Miles City, Montana late last night. Six people were all shot and killed at a gas station," you explained as you walked around the conference room, passing out case files to the team.

"Robbery?" JJ asked.

"No apparent motive," Rossi replied, glancing over the file in his hands.

"Any security footage?" Spencer asked, looking at you.

"No. No cameras, no witnesses. Ballistics say that we're looking at two shooters," you replied, pressing on the remote in your hand, bringing images of the victims up on the screen.

"Well, something at the station must have triggered them. It doesn't look like they had much of a plan," Morgan noted.

"And it may happen again," Rossi remarked. "Spree killers often repeat themselves."

"That's why we need to get going," Hotch said, glancing around the table. "Wheels up in thirty. Reid, can I see you in my office for a moment?"

As soon as Hotch had said the words, your heart lurched inside your chest and you turned around, your eyes landing on Spencer only to see that he was already looking at you, biting his lip with worry. No one said anything as they each stood from their chairs and filed out of the room, leaving you and Spencer alone.

Your heart thundered inside your chest, wrapping your arms around yourself as you walked over to Spencer, asking him, "What do you think he wants? You don't think it's about what happened at the bar, do-"

"-I don't know what he wants," he cut you off. "I'm sure it's nothing, though," he said, giving you a restrained smile as he squeezed your shoulder, the concern in his eyes evident.

"Come find me after?" You asked, gulping nervously.

"Definitely."

You watched him as he turned and left, leaving you standing there alone, wracking your brain for any possible reason why your boss would want to speak to him. It was probably nothing, though. You were just being paranoid.

Right?
