Neither Harry nor Severus talked after the agreement to give the relationship between them an honest try. They were bonded, but that was legality to keep Harry out of needing a guardian because he was married. Harry basically offered to Severus that they date within their union, and see where it went if they didn't fight what came on its own.
Harry openly admitted that not only was he gay, but liked Severus. The percentage Harry mentioned had just been a joke, but it made things light. There was no denying that ever since they talked things out before Christmas; they had gotten closer as friends, but there were moments of actual relationship factors such as the kissing, hugging, and obvious concern for one another in less than perfect situations.
Such as Harry's scar pain, or when Severus got put under Crucio with Voldemort, or Harry nearly getting his full force with a cutting curse because of a classmate trying to see just how good Harry's shielding abilities were.
That boy was still in a world of trouble too, Severus already explained in a quick staff meeting before he got summoned to Voldemort, what had happened. The teachers agreed with him that the crime fit the punishment as it could have been very bad. Either way, Harry and Severus were going to give things between them a chance to see where it went.
Right now, it went with them finally picking up that make out session from the 17th while sitting on the couch together. Both of them knew what they wanted, and there was no reason to deny each other now being on the same page with their relationship. Besides, it had been heavily hinted since Severus's birthday that they wanted to have sex again.
This would be the first time ever that it happened on school grounds, despite the fact Harry had given Severus a blowjob on the man's birthday just because. In the midst of making out, Harry moved himself to be in Severus's lap, straddling the man's lower half but never breaking their kiss as Severus put his hands on Harry's hips once Harry had lazily got his arms around his husband's neck.
At school, there was just too much chance that someone came into the room, no matter what Severus said about personal quarters being off limits without permission. Harry forced himself to break the kiss and stare at the man's face.
"Why'd you stop?" Severus asked.
"Is your room locked down?" Harry stared at him. "I know what you said, but I don't trust Dumbledore not to just make an appearance if he was concerned about you after a meeting."
"You make a good point." Severus adjusted to get his wand and wave it around in a circle around the room before he set it down on the couch side table. "There."
"Now…Are we doing this out here in your main room, or should we move to the bedroom?" The teenager inquired.
"Bedroom." Severus told him lightly.
Harry grinned before leaning back in to capture Severus's lips and the potions master returned the action instantly. It didn't take them long to get back to what they'd been doing before Harry stopped things to ensure they wouldn't be interrupted. Of course, it wouldn't stay like this either.
Harry eventually brought his from around Severus's neck to start working those buttons on the man's nightwear, which really wasn't all that different from his normal attire. This time, Severus just wore quite soft black pajamas, so the only buttons Harry had to undo were the ones of the shirt and it didn't take long to finish that so Harry was able to pull the fabric apart to get an enjoyable view of the man's chest.
The teenager never broke the kiss, but ran his fingers up Severus's exposed skin lightly, making the older male groan slightly into the kiss at the touch. Harry had such soft hands that worked something similar to a massage once reaching Severus's shoulders again.
Harry eventually moved off the man's lips and began to kiss along his jawline, and playfully nipped the male's ear, causing Severus to let out a very unmanly moan. Thank God his room was soundproof because the sound that escaped his lips had been loud, but Harry knew it was one of enjoyment.
"Th-Thought we were going to the bedroom?..." Severus questioned as Harry's lips were now on his neck, licking a spot that joined up with the shoulder. Harry seemed to have found quite the sensitive place that he was committing to memory.
"I didn't say when we were going." Harry kissed the man's hooked nose with a smile.
Harry returned his lips on Severus's, but not for too long as the teenager began to shift himself off the potion master's lap and get himself kneeling on the floor, having kissed all the way down the exposed skin of Severus's toned chest and stomach.
Severus blushed when Harry's hands were on the waistband of his bottoms, but the man knew what Harry wanted him to do, so he raised his lower half off the couch enough for Harry to drag the pants down and pull them off completely.
Thankfully, despite being in the dungeon, it was incredibly warm in the room so the chill of being unclothed didn't get to Severus. Harry now pushed Severus's legs apart to shuffle in closer, and he rubbed the man's legs with his hands while peppering kisses along the man's inner thigh. Severus just kept himself relaxed in a semi-reclined position on the sofa as Harry lightly grabbed hold of the man's hardened prick and began to stroke up and down.
"Ha-Harry…" Severus moaned.
The teenager rested his arms on Severus's legs before bringing Severus's cock into his mouth and beginning to lick around and bob his head to suck. Severus gasped in pleasure and gripped the couch cushion with his hands. Harry kept on what he was doing, sucking and stroking Severus's length, bringing the man closer to completion with each quickened movement of Harry's warm and wet mouth.
"H-Harry! I'm going to-," Severus barely choked out before the man's body tensed up and his hips jolted. He came without any more warning than what he managed to force through the moans. Harry never moved, he took the load in his mouth and swallowed.
Severus was left limp on the couch, breathing hard and fast with his head thrown back to enjoy the feeling as it rushed through him. Harry pulled off, performing a wandless and wordless cleansing spell on his mouth before getting off his knees and shifting forward to steal a kiss from Severus and smile at him. "The hell, H-Harry…You've never done that before…"
"Just because I haven't didn't mean I never would," Harry chuckled. "Feel alright?"
"Fantastic," Severus replied.
"Wait until I make it amazing," Harry stood up straight as Severus finally forced himself to sit forward. "Ready to go to the room?" He asked. Severus never answered as he reached out to put his hands on Harry's hips and pulled the teen closer to him, then his hands started working on Harry's jeans, undoing the button and pulling the zipper down. "What are you doing, Sev?"
"Doing the same back to you?" Severus responded. "Unless you don't want me to, I should have asked what you prefer. Not only that, but we also already set that I'm bottom and you're top between us."
"I don't mind if you continue, I was just surprised that you were. No, I definitely don't mind you doing anything back to me. I know we set our places before we got married, but I'm happy to switch if you want to." Harry lightly wove his fingers through Severus's hair and cupped his cheek. "Go on if you want to do it." He invited. "I can sit down if that's easier?"
"This is fine for me," Severus carefully tugged Harry's jeans and boxers down, but not all the way, just enough to set Harry's hardened cock free from the constraints of his pants. Severus had never done this for Harry, but he wanted to, so they could both enjoy the pleasure.
Severus wrapped his hand around Harry first, pumping his hand back and forth as Harry sighed out and closed his eyes, hands still in the man's hair and running through the dark locks. Severus eventually held Harry's prick in hand before licking around head and bringing the length into his mouth fully.
Harry's head went backwards, face towards the ceiling and eyes still closed and hands now gripping the man's shoulders as his husband sucked him off. Harry breathed hard and moaned with each movement, especially after Severus started to pump Harry's cock in rhythm with his mouth. "Sev'rus…" Harry moaned. The potions master found that he enjoyed Harry using a different variation of his name in that near breathless moan. "Oh, God…Sev," Harry tightened his grip on the older male's shoulders. "I won't last if you keep that up…" Harry informed. Severus did have to mind that Harry was still a teenager and his stamina was likely low given the inexperience.
That wasn't to say Harry was bad, but he probably didn't have a lot built up, Harry admitted he only had sex with Blaise for the short amount of time they did it when the two dated. Severus finally stopped what he was doing and looked up at Harry managed to fix his head to look down at the man before readjusting to bend down and give him a kiss.
"Room now, or I'm taking you against the couch, a wall, or your desk…" Harry whispered as he kicked off his shoes, then removed his pants fully. The shirts were lost a while back during making out. Their clothes were strewn about the chamber and neither one of them cared. Severus's cheeks flushed as he nodded and got up, taking Harry's readied hand.
The two of them walked to the bedroom and Harry didn't waste time immediately capturing Severus's lips once inside, and Harry expertly used one of his feet to kick the door closed then walk his husband backwards until they both laid down on the bed, Harry over Severus while they made out.
"Harry…Please, I want you…"
"Patience, love," Harry smiled. "You have lube, or should I use the spell again?"
"Bottom drawer of the nightstand…" Severus told him. Harry gave the man another short kiss and then crawled himself over to the bedside table to grab the bottle of lubrication, then return to his husband.
Severus already had himself rolled over to his hands and knees. Harry got some of the lube into his hand, then set the bottle down to use again later. The teenager worked the lube around his fingers and then the excess was smeared between Severus's cheeks and over his hole.
Harry kissed down the man's back a few times while using his fingers to massage his husband's entrance, then finally, Harry gently worked a single digit inside of him. "Ha-Harry…!" Severus moaned. Harry smiled as he kept one hand on the man's hip and used the inserted finger to prepare the male.
It didn't take too long for Harry to pull back and come back with two inside. Severus lowered his front to the bed, effectively spreading himself more. Harry's fingers pumped in and out, occasionally striking the prostate and making Severus choke out another moan.
"Please? Harry, God…Please! Fuck me…" Severus pleaded. Harry used his free hand to get more lube on his own cock and then rub it around properly. The teenager kept his fingers in place until the last moment, slowly inching his cock closer to the hole and finally switching them out. Harry withdrew his fingers and pressed his prick inside slowly, not wanting to just ram Severus.
"Yes! Ha-Harry! Oh, God." Harry had to fight himself on releasing instantly at the feeling of being buried in his husband's ass. Even with the prep, Severus was tight and Harry had already been on the brink of cumming once. Harry didn't even move right away, he moaned and shivered to try and relax. "M-Move, please..." The potions master asked. Harry took a few breaths and then held Severus's hips before starting to rock himself in and out of the man.
"Fuck…" Harry moaned at how it felt.
Harry kept it steady, but not overly deep or hard; he knew he wouldn't last if he did that. This was fine, Severus didn't seem to be asking for more yet. The two of them didn't stay in the one position long, switching it up to be laying on their sides and Harry holding one of Severus's legs up.
It worked for Harry to be able to kiss Severus on the back of the neck and shoulder. Eventually, the pair changed positions again, this time for Severus to actually be on top of Harry and rocking back and forth while Harry held his hips, or grabbed hold of the man's cock to stroke him. Neither of them knew what time it was while they made love, and neither cared either.
Harry refused to call this just sex, it had meaning and wasn't being rushed so they could draw it out and enjoy fully. However, it was good enough that they wouldn't last much longer. Harry had already been struggling not to finish and Severus had to work back up to cumming again as he had done so once already.
"P-Put me on m-my back…Harry, please…" Severus asked. With an easy adjustment, Harry pushed upwards to reverse them so that Severus was down on his back and Harry between his spread legs. "God…Fuck. More…" Severus moaned.
"More?" Harry smiled. "What do you want, love? Tell me."
"Faster…" Harry knew this would be the end for them; Severus wanted to cum and this was his way of telling Harry that he was getting closer to it. Harry willed himself to wait for Severus and started to rock his hips faster. "Ha-Harry, oh, God…Mm, fuck!" Severus tried to reach for Harry, bringing him in to kiss him.
"De-Deeper! Harry, deeper…Please. I'm so close!" Harry shifted a bit to spread Severus's legs more, and then get them hung over his arms. Severus moaned out, feeling Harry sink into him deeper now, and the man wrapped his arms around Harry's neck to pull him down into a passionate kiss.
"Sev…Gods, I'm not gonna last." Harry thrusted into him harder.
"A-Again…Do that again!" Severus demanded.
"What?" Harry asked. "This?" He went harder again.
"That! Yes, that! K-Keep doing it…Please. Oh, please, Harry…I need it." Severus begged.
Harry adjusted himself right to thrust into his husband's ass faster, harder, and deeper. Severus practically cried out, throwing his head back. "This what you want?"
Severus didn't even respond, his moans said it all. At this point, Harry was pounding into the man; the sound of slapping flesh echoing in the room. "F-Fuck…Harry, yes! Oh, God, just like that…!" Harry was losing himself; he wouldn't be able to hold back any longer at this rate.
The teenager quickly adjusted his arm around Severus's leg and grabbed hold of the man's throbbing cock, beginning to stroke him in rhythm with his thrusts. Severus choked out another broken moan, his breath hitching. "Yes…Yes! Harry, fuck…Please! I-I'm going to-I can't-…!"
"Cum with me." Harry ordered, biting the man's lower lip.
That was all it took. Both of them let go, cumming quickly. The moment Severus came, he'd arched off the bed and Harry spilled into his husband's ass while Severus's load ended up across his midsection and over Harry's hand. They'd called out each other's names on finishing, and neither of them dared to move as the orgasmic rush rippled through them in waves.
Harry had let go of Severus's cock, and the only movement made was when Severus pulled him closer to kiss him deeply. The two shared smaller kisses after that, trying to catch their breaths as Harry had pulled out and lowered the man's legs. Neither wanted to move from this position, cocks slowly becoming soft against one another.
When the high wore off, Harry and Severus didn't want to do anything else, but forced themselves to move correctly on the bed and lay down. Severus cleaned them both with a non-verbal Scourgify, obviously without a wand too since it had been abandoned in the main room, as was Harry's and all their clothes.
"I should get back to the dorm…" Harry muttered tiredly.
"Like hell you're going anywhere, Harry." Severus told him. "Stay with me tonight. After that…I'd really like to enjoy falling asleep with you, stark nude…The way it should have been after we consummated the marriage."
Harry remembered January 1st when he and Severus stayed up, how the man said that their bond was powerful and it had been wrong of Severus to send Harry out of the room after what they did as things didn't mesh properly with their magic. Tonight had been the first time they had actual sex since the wedding, and with how willing and perfect the event went, Harry could feel the mingled magic in the air, the energy of their copulations mixing.
"Alright, Sev," Harry replied softly as they cuddled up under the blankets.
"Tonight was amazing…" Severus admitted.
"Told you I would make it so," Harry teased.
"Brat." Severus rolled his eyes.
"Your brat…" Harry snuggled against his husband, yawning. "Let's get some sleep. Night, Severus." Harry began to drift off.
Severus kissed Harry's forehead. "Goodnight, Harry…" He replied and laid awake as the sounds of Harry having fallen asleep hit his ears. Severus stared up at the dark room, Harry's words running through his head. Your brat is what Harry had said. Calling himself Severus's. The man pulled Harry closer. "Mine you are indeed, as I am yours." After that, Severus let sleep take him.
