Sanctus Espiritus, redeem us from our solemn hour
Sanctus Espiritus, insanity is all around us
Sanctus Espiritus, is this what we deserve,
can we break free from chains of never-ending agony?

Mark Sloan lied on his back and stared at the ceiling. His silver iPod sparkled delicately, laid on navy blue satin bedding in the evening light; the sun was setting and covering the city in a warm, rosy glow, which shone through a big window onto doctor's semi-naked body. Mark's chest hovered steadily and he had a running thought stream. He couldn't forget how he and Avery treated Little Grey. Was that too much for her? Was that too little? How is she going to react?

For a few past days Lexie moved around the hospital acting a bit high; she stared at things, dozed off in the middle of a conversation and had eyes fogged with what was either fatigue or dizziness.

Are they themselves to blame, the misery, the pain?
Didn't we let go, allowed it, let it grow?
If we can't restrain the beast which dwells inside
it will find it's way somehow, somewhere in time.

The door to his apartment croaked; it was most possibly Arizona handing over Sofia for her daddy day care time. Or evening care, more like. He rubbed his bloodshot eyes and called 'Coming, coming.'

He sat up, reached for the nightstand's drawer and tried to pick a pair of decent enough pajama pants. He managed to find a pair of dark blue pj's and put it on, jumping around a bit. He opened the door with a bright smile on his smug face and quickly felt his trap opening wide.

Who stood in front of his kitchen peninsula was not Arizona, not ever Callie. It was Jackson Avery, leaning casually against a bar stool with a smile of punished kid. He was wearing a pair of faded jeans, hugging his features nicely, and a white wife beater with a frayed hem. His Adam's apple bounced up and down as he swallowed loudly at Mark's view. His eyes darted to the floor and fixed on the carpets tassel.

'My progeny' said Mark a bit unsurely. 'What are you seeking, advice or booze? Because believe me, Team Pediatrics won't be happy having you around my baby girl while discussing some nurses ass-'

'Cock.' Jackson looked up with a straight face and observed how Mark took an absentminded step back. Both men stared at each other; the older one with utter bewilderment, the younger with patient await. Jackson cocked his head and slid his sight down Mark's toned chest, right up to where a trail of silver-black, coarse hairs marked the path to heaven. He licked his full lips suggestively and shot his teacher a hungry look.

Mark Sloan gulped and opened his mouth to say something, but quickly shut it again. He has had men before; sure, Derek's drunken colleagues from the chess club, fraternity mates, and his fellow from New York's Mercy… but her never had sex with someone younger than him, not to mention his subordinate. His unruly member grew hard upon the memories of sweet fucking right under his dean's nose, underneath a clothed table during an assembly.

Jackson caught that change and smirked lustfully. He took a step further and took of his tired wife beater, exposing a muscled body, glowing with sweat and in beautiful, mocha coffee color. He let it fall on the floor and moved it around with his bare foot. Mark looked down to buy some time, still unsure what to do.

The younger doctor unbuckled his belt and started toying with it. He took another step towards frozen Mark and touched his bare chest with a free hand.

'I want you when you are performing a surgery.' His voice was dark and resembled a growl of an animal. 'I think about sliding my hand down your thigh and watching you squirm.' He put both hands of his tutor behind hypnotized Mark and grabbed his neck. The wide, brown leather belt was now collared around it, making it possible for Avery to strangle him a bit. 'And the only thing that makes me stop is the human life you have in your hands.'

The belt pressed hard on Mark's larynx. He followed Jackson, who was clearly heading towards the couch. His swollen cock was now visible under his pajama pants and throbbed, begging to be touched and fondled. Avery made him sit on the sofa and stood in front of him with much admiration for his tutor's aroused body, smelling of brandy, shampoo and sex.

'You like it, don't you.' He bent over so that Mark's face was right in the front of his. 'You like it very much. You are a bossy know-it-all, but you take pleasure in being bossed.' Jackson opened his mouth a little and bit Mark's lower lip. Older man's eyes grew dark with lust and anger. Jackson toyed with him Humiliated him.

Avery chewed on his teacher's lip and then attacked his mouth with a hungry, aggressive tongue. Mark welcomed it with a groan, still feeling a very mixed and undefined mélange of emotions. They kissed for a while, and then Jackson broke the kiss and straightened up. Mark had to look up to see his face and felt humiliated once again. Avery tugged the belt, still wrapped around Mark's throat, and forced him to kneel on the floor. He took a tie, lying alone in between cushions, where Mark must have left it while undressing, and tied it around the older man's eyes.

He was blinded. He felt his hearing go sharper as his brain tried to readjust to sudden lack of vision. He heard Jackson move behind him and open some kind of a container, presumably a plastic one. He squirted something out of it. His apartment's door were opened and closed, and light footsteps went right beside him. The rich, plush carpet made it impossible to decide who went in, but he suddenly felt very uncomfortable.

'Jackson', who the hell-'Soft mouth claimed his, and a pair of little hands scratched his chest. The combination of smells that the hair of a stranger emitted was instantly recognizable.

Lexie Grey joined them.

Mark felt her sitting in front of him and then lying down on her back, legs spread on both his sides. She took his one hand and guided it towards her breast. He inhaled deeply. Little Grey was stark naked, lying on his carpet and Jackson was walking around. What the actual fuck is going on in here.

Suddenly he felt himself being pushed forward. Avery grabbed his left arm and made him position himself on all fours, with Lexie lying underneath him. She tugged in his pajama pants and slid it off, revealing a swollen cock. She took it in hand, ignoring Mark's audible moan, and moved herself a bit forward so that he would point with it at her entrance. At the same time Jackson grabbed his buttocks and slid a finger into him. It was a foreign sensation, since Mark was always the active part in gay sex, but he welcomed it with a hiss of pleasure. Avery moved it a a bit I and out and added another finger. After a few minutes of sliding in and out of Mark's hole, Jackson positioned himself against it and thrusted in.

Sloan let out a slight scream, mixed with Lexie's moan. He realized that the power of Jackson's thrust made him enter Lexie, who now wrapped her legs around his waist. Avery retreated a bit and thrusted once again. It felt aggressive and weird, but also very pleasurable. The younger doctor kept sliding in and out of Mark, who delicately passed the motion onto wriggling Lexie. After a few moments Sloan drowned in pleasure, his cock being wrapped with Little Grey's tight walls, warm and wet, his ass being ridden by furious Avery, who every now and then tugged a bit on the belt to suffocate Mark. Explosion of oxytocin fired in his brain when Jackson hit his prostate; pure bliss made him deaf for a second. Avery changed his angle so that now Mark was hit on his gland with every thrust, and Lexie moaned now in a series of short crescendos, being fucked violently by Sloan. He grabbed her cute arse to lift her, so that he would reach further, deeper. He was close to coming, and it seemed like Jackson wasn't far away either

'I'm gonna come' exclaimed Lexie between short breaths. Mark felt her muscles contract and laid her down, delicately as possible and flunked forward, taking Avery with him. Lexie arched her back and screamed loudly. Sloan hit his orgasm at the very same second, squirting his seed allover her stomach. Jackson threw his head back and exploded into Mark's pulsating arse, trembling as the waves of his orgasm made him collapse on the floor, right beside panting Sloan who hid his face between Lexie's breasts.

After a minute or so. Lexie took the tie of Mark's sweaty face and wiped his forehead with it. He took a look around; Jackson was already fully clothed.

'You've had a pretty damn good dream tonight. You really should go to bed now.'

She stood up, put on a loose trench coat and walked out of the apartment, followed by Jackson in his faded jeans and a tired wife beater.
