Harry stayed perfectly still. Even with his invisibility cloak, he didn't want to run the risk of exposing what he and Severus had just been doing to McGonagall. Severus was still hard and twitching inside his mouth and the pause made Harry realize his jaw had started to ache from holding it open around Snape's massive member. He heard Minerva's emerald green robes swish as she strolled purposefully into the potions classroom. She stopped directly in front of the desk, mere inches from where Harry was on his knees. Harry felt like any moment she would realize he was there, even with the cloak covering himself and Severus' privates.

"Hello, Severus, I was meaning to talk to you about some potions for Madam Pomfrey. Several of our muggle students have come to her with incurable colds and she needs your help dealing with the virus before it spreads any farther."

Snape nodded with some effort and cleared his throat. When he spoke, his voice cracked. "I see. I'll have some potions for her by the end of tomorrow."

"Thank you, Severus," McGonagall said, smiling at the students. "Also, would you happen to know where Harry is? Kingsley sent an owl for him. Don't worry, it isn't urgent."

Snape swallowed heavily, the sound seeming to echo in the silence of the room as the students had busied themselves with their work. "No. But when I see him, I'll be sure to tell him he is needed."

Harry's mouth was full of saliva and Severus and it was getting hard to hold himself back from swallowing down some of the gunk seeping into his throat. He closed his eyes in concentration, willing himself to relax the muscles in his mouth. In doing so, his tongue slipped around Severus' shaft the slightest amount, causing him to gasp. McGonagall didn't seem to notice Snape's distraction. Harry sat there and smirked around the length in his mouth. This could be fun… Severus' hand was still on his head, his fingers slipping through his tangled hair and they tightened around the strands as Harry began to suck lightly. To Snape's dismay and Harry's devious delight, McGonagall didn't make an effort to leave. Instead, she dragged Severus into a discussion about St. Mungo's asking for his werewolf potions for distribution. Harry continued to suck, pulling off and swirling his tongue around the head and then moving down to his balls. He took one into his mouth and Severus grunted, pretending to nod in agreement with whatever McGonagall had said. Harry rolled the other one in his hand as he sucked and licked and nibbled. Severus gave his hair a firm tug and Harry moaned almost inaudibly as he made his way back up to the shaft of hot flesh that was bobbing in the open air. He plunged his mouth down to the root and had no intention to ease up this time. Severus' cock was dripping precoma at an alarming rate and Harry knew it wouldn't be long.

After several more minutes, McGonagall turned to go and Harry couldn't take it any longer. He swallowed. Severus went stiff and doubled over the desk, letting out a growl as he released his seed down Harry's throat. The students all looked at him with surprise, McGonagall's expression was tinged with surprise and worry. Harry heartily swallowed several times, enjoying the salty taste of Severus in his mouth, before pulling off and quietly slipping Severus' now flaccid penis back into his trousers and buttoning them before pulling that portion of his robes closed.. "Are you-"

"I'm quite alright, I assure you," Snape said shakily. Knowing Harry had hidden the evidence of their activity, he stood and ushered her out the door as the bell chimed the end of the period. "Just had a stomach cramp. Please do not worry, I have a potion for it and I will take it immediately. Perhaps you could do a favor for me and cancel my next period as I am not feeling quite well?"

With that, the wave of students swarmed to the door, taking McGonagall in their tide and Snape closed the dungeon door behind them, securing the latch. Harry crawled out from under the desk and let the cloak slip from his shoulders.

"You imbecile! You could have gotten me fired for your foolish indiscretion!" Snape fumed, turning around. He stopped short.

"Yeah, I did think about that. I thought if we didn't get caught it'd be worth it though," Harry lounged, completely naked, against the desk. He saw Snape swallow and smiled. Lifting his arms to stretch, he watched as Snape's pupils dilated and his nostrils flared. Severus had told him on many occasions - when they were deep in the throughs of passion and he thought Harry wouldn't remember - all the little things that Harry did without notice that drove him into madness.

The way you stretch when you throw your arms above your head pulls the muscles in your abdomen taught and I wish to do nothing more than hold you in that position for hours and lavish them, worship them with my hands and my mouth… you have no idea what you do to me, Harry. You have no idea…

Harry smiled at the memory and beckoned Snape with a finger. Snape complied, racing across the classroom at record speed and into Harry's arms. Harry tilted his head to grant him access to the sensitive skin of his neck and shivered in delight as a tongue licked a stripe up to his ear before nibbling on his lobe. Severus placed his thigh between Harry's and Harry's breathing hitched. His dick was at half-mast from sucking his lover to completion and Harry finally acknowledged his own discomfort.

"You know, I'm rather glad you did that," Severus breathed in his ear. "Now I can take my time with you."

They barely made it to the bedroom before Severus was upon him. He stole Harry's mouth in a kiss that was down-right feral and didn't let go until Harry was nearly faint from the lack of oxygen. Not that he minded being kissed dizzy by those talented lips and tongue. Severus pushed him roughly backwards onto their bed and Harry bounced. Raising himself onto his elbows to look at Snape, he watched transfixed as Snape slowly popped each button of his black robes free before letting the fabric fall off his strong arms and to the floor. The rest of his clothes soon joined it and Harry moaned long and low when he was fully naked, every inch of his ivory skin on display. His green eyes met Snape's onyx ones and he shivered at the uncontrollable lust he found buried beneath the surface of this disciplined man. And all of it was for him. The edges of Snape's mouth lifted into a seductive smirk and he leaned down to kiss Harry's neck. Before long, he was settled on top of Harry, a hand in his long black hair and a whimper on his lips. Snape loved the little noises he made, Harry was always so responsive to every touch, every kiss.

Snape began to lavish every inch of him with sensation, sucking a nipple into his mouth while lightly palming Harry's straining penis. Harry gasped when the cool hand met his hot, hard flesh. He closed his eyes, giving himself into whatever pleasures Severus would undoubtedly give him. When Snape pulled his nipple, Harry gasped and arched off the bed, desperately chasing those teeth to relieve some of the tension. The hand on his member moved up and down, chasing him closer to the edge.

"Harry, open your eyes. I want you to look at me."

Slowly, and as though it took all the effort in the world to obey, Harry opened his eyes.

"Good boy," he heard Severus say. "Keep looking at me. Don't take your eyes off me, do you understand?" Harry nodded his head before wet heat closed around his stiff cock. He cried out and almost closed his eyes again, grasping at the bedsheets instead. Severus' eyes were on him as he watched his cock slowly disappear into his mouth. The sight filled his vision and he couldn't help moaning again, Severus returning the sound and sending vibrations down his length.

"S-Severus! I c-can't hold on much l-longer!" Harry stammered through clenched teeth. Severus pulled off with a wet pop and he reached across Harry to open the drawer to the bedside table. His chest was almost touching Harry's nose and Harry breathed in the scent of his lover. Overcome by the sudden feeling of loneliness, he wrapped his arms around him and buried his face in that broad chest before Snape could protest.

"Harry? What's wrong?"

Harry smiled as he felt the chest rumble his name as arms closed around him. He had missed the feeling of those arms encircling him; missed the way his name sounded when it came from those lips. He had missed his company, his casual banter and conversation. He had missed having someone beside him as he slept. He had missed the casual touches he would give and receive, or the way Severus' eyes always seemed to caress his body when he thought Harry wasn't looking. He had missed this man so very much and he never wanted to leave that bed again.

"I love you," he said instead, because honestly, it summed up everything.

He felt Severus relax against him. "I love you too, Harry."

Harry released his hold on the man so he could cup his face and his him. Snape kissed him back tenderly and without hurry, as if they had all the time in the world. The tenderness didn't last forever and soon enough they were both hard again. Severus opened the jar of oil he had grabbed and poured a large amount onto his fingers before inserting two into Harry's waiting opening. Harry sighed at the feeling of being filled and pushed back, moving himself over those long, slender digits. Severus added a third, scissoring them in and out slowly, making sure to rub against Harry's clenching muscle with his thumb. When a finger brushed against his prostate, Harry couldn't take it any longer.

"Sev, I need you inside me," he said, panting.

Snape nodded and pulled his fingers free of Harry before slicking up his cock. He placed a kiss to Harry's forehead as he leaned over him and pressed the head inside. Harry hummed in appreciation of the stretch before Snape began to move, undulating his hips and thrusting inside to the hilt.

Severus moaned and said, "Merlin, you're so tight!"

He lifted one of Harry's legs over his shoulder and began to fuck him harder and Harry encouraged him, moaning and gasping and babbling nonsense as Severus battered his prostate on every thrust. Snape's other hand was around his penis, slick with precoma and oil. They didn't last long. With a final stroke, Severus pulled all the way out before slamming back inside, causing Harry to scream his name as he came. Severus bit Harry's shoulder as he released his load inside of him, Harry's tight channel milking every drop from him before he collapsed on top of him. They both breathed heavily for a while, caught in a state of post-orgasmic bliss.

When Severus moved to pull free, Harry clung to him and said, "No, please… I want you to stay inside. Please…" Snape smiled fondly down on him and rolled them over so that Harry was on top of him. He stroked his hair as Harry rested his face on Severus' chest. "I missed you, you know. I don't like being away for so long, it does awful things to me; I get grumpy, I can't focus, I can't think straight."

Snape hummed. "I feel the effects as well. These past weeks I have been… less than fair to the students because of your absence. I feel it keenly whenever you are away from me."

"Less than fair," Harry snorted. "When have you ever been fair to students?"

"Always. I demonstrate to them their lack of effort or understanding and they simply fail to use my criticism to further themselves."

Harry smirked. "Of course you'd see it like that."

Snape looked at him tenderly. "I was extra hard on you because of my feelings. With everything that was going on… I just couldn't risk it. You meant more to me than anything and that scared me."

Harry blinked at the admission. "Does it still scare you?" he asked quietly.

Snape smiled at him and gently ruffled his hair. "Yes, but only because I know I could lose you. I don't know what would become of me if that were to happen. That's why I hate your job so much; not because of the bad publicity, not because you're away so much, but because of how dangerous it is for you. I don't want you getting hurt. Every time you go for weeks and I don't hear anything, I get sick with worry."

"I'm sorry, Severus…"

"For what? You're doing what you love, you're helping others who are less fortunate than you. Why do feel you must apologize for an old man's fears?"

Harry kissed his chest. "You're not that old."

Severus laughed, the sound forming in his chest and cresting over his lips like a tidal wave of sound. It comforted Harry to hear it after so long. It caused the cock that was still inside him to shift, a change that made Harry's heart skip a beat at the feel in his sensitive channel. He spread his legs a little wider, Severus' cock slipping out just a bit. They both moaned and Harry felt himself getting hard once again.

"I might not be, but I definitely can't keep pace with you." Snape said playfully.

Harry smile at him and kissed his chest again. "Maybe, but I'll make it worth your while."
