After breakfast, Severus insisted on looking Harry over, to see that his injuries were properly healing, or so he said.
Looking the boy over, running his fingers lightly over the pale pink marks on Harry's skin that would soon fade to nothingness, thanks to his potions and creams, Severus realized that he was starting to get aroused, very aroused, just from touching the boy.
Merlin, please don't let the boy notice, he silently prayed.
Apparently Merlin wasn't looking out for Severus right then, because as Harry turned around to point out a larger scar on his side that he was worried about, his eyes drifted down Severus' body, to his arousal that was getting more prominent by the second, it seemed.
"Oh Seeeverus," Harry said slyly, "I think you like me a bit more than you like to pretend!" Harry took a step forward and before the potions master could say anything, he planted a hungry kiss on him. Shocked and unsure of what to do, Severus returned the kiss with just as much heat as Harry had given.
Pulling back, Harry grinned. "I always knew that you secretly liked looking at me. It's no wonder you had me on my hands and knees scrubbing those floors, you were just staring at my arse!" he teased.
His only answer was a deep growl that Severus didn't know he had in him.
Taking that as an invitation, Harry reached down and unbuttoned the older man's pants and started tugging on the zipper when Severus reached down and grabbed his hand. "Not here," he panted, picking Harry up and carrying him to the bedroom.
Dropping Harry on his bed and watching hungrily as the young man scooted backward on the bed, making room for him, he pulled off his shirt and climbed on the bed toward the boy.
"Beautiful, delicious, Harry Potter in my bed, eyes practically begging me to fuck him and…" Severus didn't have a chance to finish his thought before Harry pushed him over and crawled on top of him.
This is something Severus wasn't accustomed to, but with a hot young lover like Harry on top of him, taking change, he was sure that he could get used to it.
Harry's arousal was now quite prominent through the thin material of the boxers he was wearing and the friction of it rubbing on his stomach only made Severus want him more.
He reached down and grabbed the young man's arse and pulled him down onto his lap and grinded his hips. Harry brushed Severus' hair back and leaned down to begin exploring his neck. With every nibble and kiss another hiss made its way out of Severus' mouth and only made Harry even more eager to continue. He found Severus' pulse at the base of his neck and found that he could make the man crazy if he sucked on that spot.
Merlin! The boy knew what he was doing! Severus thought.
Soon he was on his way down the man's chest and when he nipped the man's nipple he groaned and rolled his hips toward Harry looking for something, anything, to rub against.
He suddenly pulled Harry back up and began a similar attack on his jaw line and neck. He snaked a hand down between Harry's legs and firmly squeezed the younger man's cock and as Harry gasped, bit down on his shoulder, bringing a throaty moan from the younger man's throat.
Severus grabbed his zipper and worked his way out of his pants, never stopping the hungry kisses and the assault on Harry's neck.
Once they were both in nothing but boxers, Harry sat up and began grinding on Severus' lap, driving him crazy. Just when he thought he was at the point of no return, Harry rolled off of him and snatched off his own shorts, and quickly followed with Severus', before he could complain.
Severus grabbed and pushed him onto his back and began to tease him mercilessly, licking him from root to tip and back again, never actually taking him into his mouth and tickling that little bit of skin between his balls and arse.
Severus cast a cleaning charm and then a lubrication charm on Harry, and started teasing him with the head of his cock. Harry tried to push against him, wanting to take him all in, right now, but he grabbed the younger man's hips and held him still, continuing the tease.
"Beg me for it," Severus teased.
"Oh Merlin. Please. Now!" Harry panted
"Now? Now what?" he asked wickedly.
"Please. Fuck me! Now!" Harry begged
That's exactly what he wanted to hear. Severus slid into Harry, and buried himself all the way to the root before he stopped. "Alright?"
"Yes! Oh fuck! Oh!" was all that he needed to hear. He began pumping in and out of Harry hard and fast, but he soon slowed down, gliding in and out of him in a slow, leisurely pace, driving the young man to beg again.
"Please, Severus, Please! Oh! Harder Severus, Harder! Please!"
He was more than happy to oblige.
