Chapter One: New Beginnings

Harry sat in the window seat of his third floor London flat watching the rain pelt the glass and the people bustling about below. He closed his eyes and sighed, he missed Sev. The feeling was always prominent when it was dreary outside. It had been five years since he had last seen the man he had always hoped to be with once they had reached an understanding, and he still longed to be near him. Wrapped tightly in the strong tender embrace of his lover.

He groaned as he opened his eyes and rubbed his temples, Harry knew exactly where this train of thought lead and he knew self fulfillment never satisfied the cravings he harbored these days.

As he leaned back against the frame of the window seat, watching the rivulets he crossed his legs beneath him and decided to focus instead on their last night together, these thoughts alone were enough to make his blood run as hot as molten lava from an erupting volcano in Tahiti and then freeze as though he had just been trapped in the next ice age. Harry closed his eyes again as he let his thoughts carry him away.

Harry lay ensconced in Severus' arms on a fur rug that smothered the coldness of the stone dungeon floors in front of a warm fire. He sighed contentedly as he trailed his fingers lightly along his lover's arm, admiring the sheen of sweat that glistened across their bodies from their prior love making.

He was happily day-dreaming about their future as tomorrow would be his final day at Hogwarts and he would be graduating with the rest of his class mates and would finally be able to lead his life with Severus by his side. He would finally be able to tell his best friends about his relationship with the Potions Master extraordinaire Severus Snape. Harry was just imagining their reactions and his future days of assisting his Sev with potion experiments until he figured out what he wanted to do himself, when Severus' voice broke his train of thought.

"Harry….we need to talk."

Harry suppressed the urge to shiver at the tone Severus used, it reminded him of the days during his first through fifth years when Severus had hated him, well appeared to have hated him, and would demean him in front of his classmates. Even though Severus' voice seemed to flow over him and trough him like warm honey, he knew now was not the time to be aroused. The voice was dead calm, serious. He hated it when Severus was serious, it always meant something was wrong, and it was something he would not like to hear. Although he couldn't imagine what, they had long since defeated Voldemort even if it was in a low key battle with only two words having been spoken between them "Avada Kedavra", their relationship, albeit a hidden one, which Harry himself didn't like that aspect, was perfect in every way he could think of. He loved Severus. He couldn't fathom the concept of ever being with anyone other than the snarky git. True, he had never been with anyone else, but he didn't want to be either. He had known that he loved Severus since his sixth year when he was forced to study the Dark Arts with Severus, no Professor Snape at the time.

Emerald looked up to meet Obsidian.

Harry stared into those eyes trying to unlock the emotions that had been carefully placed behind the mask he had come to know from Severus' days as a spy, but were unable to discern any raw emotion within their depths.

Severus hated himself for what he was about to do , but he knew in his mind even if his heart wanted to tear him apart for the amount of pain he was about to inflict upon his younger lover, it was the right thing to do. He couldn't, he wouldn't be the one that held Harry back. Harry was eighteen, twenty years his junior, sure the brat had wormed his way into his life and was no longer the-boy-who-lived, but now the-man-who survived-and-defeated-he-who-can-now-be-named. But his, yes his, Harry, had still yet to experience a true life. Severus knew Harry needed to live his own life, create some happy memories for himself, lord knew the boy needed some. Severus set his resolve and his jaw at the same time.

"Harry. I want you to leave. For good. I don't want you to write or fire call. I don't want to see you ever again."

There it was said. The air seemed to hang ominously in the air, stifling him. Severus knew Harry was wise for his age, he also knew Harry could still be a child, he prayed that Harry would be the former at this time. He wouldn't be able to hold his ground if Harry asked him not to.

Harry laid before his lover letting his mind process what he had just been told. He closed his eyes momentarily holding in his emotions, when he opened them the mask of indifference Severus had taught him was firmly in place. For some unknown reason, he knew his lover was just trying to impart some unknown lesson on him. He knew Severus thought him young, but couldn't Sev see how much Harry needed him? How much Harry loved him? Harry knew only time would help him show Severus what he meant to him.

Harry spoke as he stood removing himself from his lover's embrace as he went around the room gathering his discarded clothing. "Very well Sev, if that is what you wish. But you will see me again." Once dressed Harry left Sev's chambers so that he could break down in the comfort of his own four poster in the Gryffindor boys' dorm.

Harry opened his eyes when he heard his clock chime. He looked up to notice the hand labeled "Ari" was currently on its way to the word home. Good, his best friend of the last three years would be home soon which meant she would be visiting him within the hour. He was glad he had decided to have her added when he had convinced her to move to London with him. At least now, he would be prepared. She had planned on taking him out to a new pub just down the way in hopes that he would finally "man up" and meet someone. He loved how stubborn his friend was but he hadn't been ready or prepared to meet someone since he was trying his best to blend in with the muggles he chose to surround himself with. The wizarding world seemed so small once he'd graduated Hogwarts and he had no desire to make his way in it after the war with Voldemort. He just wanted to be normal even if he did use his magic to make his life a lot easier than most people could. He had it, so why not use it to his advantage when need be. He just didn't envelope himself in it on a constant basis any more.

He smiled to himself, yes, he had been happy with Severus, but he was also happy with Arissa in his life, and he needed to move on. Severus had stayed true to his word, and avoided every one of Harry's attempts to contact him in the last five years. It was definitely time to move on.

He sighed as he stood up from his perch in the window seat and made his way to the bathroom to prepare for what was sure to be an evening that frayed his nerves. Running a hand through his hair he reached into the shower and turned it on so that the water would start to heat up letting the steam billow around the small area. After pulling off his t-shirt and jeans he climbed into the shower stall and closed his eyes letting the water roll down the lithe planes of his body. He still managed to retain a lithe almost swimmer's build from going to the local gym after work and he enjoyed the freedom of riding his Firebolt on the nights that he couldn't fall asleep because of stress from work or loneliness so he would fly until his limbs ached and he knew he would be able to fall into a dreamless slumber. He grabbed his shampoo and popped the cap inhaling the strong scent of vanilla that he enjoyed and would usually relax him. Running his hand through his hair he scratched his scalp giving himself a light massage while his mind drifted.

After rinsing his hair he grabbed his washcloth and began to wash his body watching as the muscled pulled and bunched beneath his skin causing him to think about times with Severus helping him wash in the shower. With those fleeting memories he felt himself begin to stiffen and groaned inwardly at his traitorous mind and body. Knowing that he wasn't going to be getting out of the shower without taking care of his now growing problem he slid his cloth covered hand down his chest, across his abs and down to his now full blown erection. He started to gently pump his hand along the flesh and let out a soft moan as he remembered one of his favorite ways of waking Severus up after one of their long nights spent together.

"Umph. Severus, you great oaf, get off of me," Harry whined as he tried without much success to slide the now slumbering Potions Master off of him. His bladder was really starting to give him a wicked beating.

He slumped back onto the bed with an extremely audible sigh and a rush of air that caused a few strands of Severus' hair to blow back off his face. Finally with a great heave, he managed to roll Severus a smidgeon further away than he was. With great effort, he squeezed his way out from beneath Severus and went to the loo.

After relieving himself, he stopped in the bathroom doorway leaning his shoulder against the door frame. He shook his head, smirking as he watched Severus just lay there. The lazy sod. Well, Harry had something that would wake him up. Even if it took the rest of the early morning hours.

With a wicked smile, Harry crossed the room and gently untangled the blankets from around Severus' legs and gingerly laid them at the foot of the bed. He grinned when Severus grunted and rolled so that he was laying on his stomach, his glorious pale arse now presented to Harry.

With an audible smack of his lips, he gently traced his fingertips up the back of Severus' calves, then his thighs only to stop on the taut buttocks and start kneading, gingerly easing the globes apart reveling at the sight of the puckered hole before him.

With a slight shiver he lowered his tongue to that sweet entrance and probed at it lightly. He continued to lap at the sweet hole, encircling the soft skin around it and tracing light patterns onto each cheek. Unable to illicit anything but a light grunt from the slumbering snake, Harry furrowed his brow. This just would not do on Christmas morning.

With an evil grin, he decided not to hold back and plunged his tongue directly into Severus' tight entrance, causing the man beneath him to jump, his eyes shooting wide and a deep moan from to issue from his dry lips. Severus canted his head back so he could cast a look at Harry over his shoulder with a raised eyebrow. "Are you trying to suggest that last night wasn't enough for you, brat?" Harry grinned mischievously and continued to lick and prod at the entrance eliciting more moans and a sharp intake of breath from Severus. After one last broad swipe of his tongue across the now twitching pucker, Harry sat back on his haunches and licked his lips. "Now, Severus, you know that I'm just a hormonal teenager that can't fight his urges when presented with the delectable sight that you provide me on a continuous basis."

Severus arched an eyebrow as he pulled himself up on his elbows before rolling over so that Harry now straddled his thighs with his now aching hard on prominently sticking in the air. Harry smirked as he looked at his lover before lewdly lowering himself between Severus spread legs and resting an elbow on either side of the man's hips and gently placed his hand an inch away from either side of the leaking penis presented to him. "Mmmm...why thank you Severus, you've just presented me with my favorite snack." At that, Harry proceeded to lick him from base to tip.

Harry shivered as the scenes from his memory continued to play out across his mind behind his closed eyelids and gripped himself tighter. After a few more strokes he came hard and sighed as he leaned back against the cold shower tiles. After a few minutes of berating himself for still thinking about his old lover he washed himself once again sending all evidence of his self imposed loving down the drain. With another sigh he turned off the shower and proceeded to begin getting ready for his so called evening of fun. Once he was dressed in a pair of dark blue skinny jeans and a black v neck t-shirt that hugged his figure nicely, he added a black studded belt, and a pair of black combat boots and ran his fingers through his hair once again mussing it up. He gave himself a once over in his full length mirror and shook his head. He knew he looked good and was confident in himself after all of his experience in both Hogwarts and the Muggle college he'd attended along with all of the self esteem boosting Severus had given him during their year together.

After another second to make sure he was indeed put together he headed out into his living room to grab his wallet, phone and keys to wait for the arrival of his friend.
