Add It Up

" Lily ? " Scorpius called quietly, scanning the room with his eyes.

"Here," came Lily's voice from somewhere on his left.

The tension in Scorpius' shoulder lifted as he let out a sigh of relief and relaxed. She had made it.

"You can take the cloak off now," he said, looking in the direction where the voice had come from, searching for movement.

"Are you sure?" the charming voice of Lily came again, only this time from Scorpius' right, startling him "Someone could come in," she added teasingly.

Apparently the little vixen wants to play, the Slytherin thought while he raised his eyebrows and crossed his arms across his chest, a cocky grin forming on his face.

Now that they were out of sight from Albus and all the other students, Scorpius felt completely at ease. This was his dorm after all and seduction was his area of expertise.

"Oh, I'm sure. But maybe you'd feel safer if I did this …" he trailed, and then pointed toward the door with his wand and cast a spell, effectively locking the door.

"Now, no one can come in … and no one can go out," he continued, taking a few steps toward the centre of the room.

Of course, a simple alohomora would unlock the door but all of his roommates knew what a magically locked door meant. Scorpius knew they wouldn't spend the night outside the dorm of course, but they would at least knock on the door before coming in, leaving him and Lily more than enough time to hide her with the invisibility cloak again if need be.

"So, I'm trapped in here with you," Lily's voice rose from the darkness at the back of the dorm, near Scorpius' bed.

"Maybe that was my plan all along," Scorpius replied, taking another step toward where he thought Lily was "Now I have you at my mercy,"

"I'm not sure I mind being at your mercy" Lily whispered, before she finally took the cloak off, revealing where she was sitting on Scorpius' bed.

How she had known which one was his, he didn't know, but that detail really wasn't important in this instant.

Neither of them had bothered lighting the room and the moon's silver rays filtering through the window were the only source of light available. But Scorpius could still see Lily's hazel gaze fixed on him. She was looking at him with hooded eyes, that assured him she knew exactly why he wanted her to come to his dorm.

"Did you enjoy the party then?" Scorpius asked nonchalantly, letting his own eyes trail up and down Lily's frame.

She had crossed her legs, opening the slit of her skirt wider and revealing her thighs a little more. Her chest was rising and falling with every breath she took and her cheeks looked flushed, probably from the few drinks she'd had. She painted a very appealing picture, one Scorpius couldn't resist even if he'd wanted to.

This friends-with-benefits idea is the best thing that has happened to me in a long time, he thought, thanking Lily internally as his eyes devoured her.

"I did," Lily replied as she tilted her head to the side "And I'm hoping the after-party will be just as fun,"

"I'll give it my very best," Scorpius swore with a knowing smile before he lifted his hand to the first button of his shirt.

As Scorpius was walking toward her, discarding his clothes along the way, a shiver traveled through Lily's whole body. Her heartbeat was frantic and hadn't actually slowed down since Scorpius had murmured this crazy plan in her ear in the common room.

This whole situation was making her feel bolder and more fearless than ever, but then Scorpius always had this kind of effect on her. The Slytherin somehow always managed to bring her wilder side out to play.

When Scorpius finally reached the side of the bed, the only piece of clothing remaining on him was his boxers and Lily decided that she had to even the score. She felt Scorpius' burning gaze on her as she started to remove her black skirt, pulling it slowly down her legs. But when she tried to take her top off, the wizard suddenly stopped her.

"No, the top stays," he declared with a deep voice.

Lily lifted an eyebrow in question but left her top alone obediently as Scorpius stepped between her legs and pushed her so that she lay on the bed.

He immediately covered her body with his, resting his weight on his forearms on each side of her head and finally claimed her lips. He kissed her passionately, licking and biting her lower lip before engaging Lily's tongue in a lustful dance. The witch didn't even think about resisting him and instead fisted a hand in his perfect blond hair while the other went to his back and tried to push him closer to her.

She felt Scorpius hand move on her body, caressing each inch of flesh he could find until his magical fingers crept underneath her top and grazed the skin just under her bra. Apparently, just because the top was staying didn't mean her breasts would be neglected.

Releasing her lips, Scorpius started kissing her chin and her neck and Lily moaned as he paid particular attention to a sensitive spot.

At hearing her response to his kisses, Scorpius straightened above her, just long enough to grab the curtains of his four-poster bed and shut them close. He also didn't forget to grab his wand and cast quick protection and silencing charms before repositioning himself and going back to ravaging Lily's mouth.

It wasn't long before the two of them started moving against each other, Scorpius thrusting his hips and Lily bucking hers in response and when the wizard released her mouth to focus on her neck again, Lily let out a frustrated mewl. Of course, she enjoyed this intense snogging session but her body was growing impatient and she desperately wanted something more than just friction between her legs.

"Scorpius, I want you," she managed to say, not recognising her own voice.

Scorpius only growled against the skin of her neck where he had just been licking and kissing her. Her hand was still holding him close, but after another minute where Scorpius just moved on to kissing the swell of her breasts, Lily decided to take matters into her own hands, literally.

She let one of her hand trail down Scorpius' chest until it reached the waistband of his black boxers. But when she tried to slip it inside to touch him, Scorpius stopped her instantly and threw her a very hungry look.

"I know you're growing impatient vixen, but tonight you are all mine," he told her, his grey eyes boring into her hazel ones "And I have decided I want to kiss you everywhere before I take you,"

Lily didn't have time to reply anything before Scorpius was once again kissing the life out of her.

Does he really mean everywhere ? she asked herself quickly.

She soon got her answer when her blond wizard lifted slightly from above her and moved his body lower. His mouth landed on one of her thigh and Lily had to gasp at the unexpected sensation.

Slowly the kisses started trailing up her thigh, getting closer to her centre and making her moan and whimper very frequently. Scorpius then used one of his finger to caress her through her thong, no doubt sensing how wet she was through the fabric. After that one touch, the Slytherin kissed and licked her inner thighs a few more times, groaning along the way, before he decided it was time to remove the black little piece of fabric and Lily just had enough time to register that she was now naked from the hips down before she felt the first lick.

"Oh Merlin, yes," Lily whispered, her eyes closed in delight.

Her orgasm took her by surprise as much as that single lick had and she shuddered on the bed, screaming Scorpius' name as waves of pleasure shook her.

Of course, the Slytherin didn't stop his assault on her but instead kept licking her slowly, waiting for her to come back to earth. And when she did, he moved his attention to Lily's clit and sucked.

She couldn't believe how skilled Scorpius was with his mouth and how he managed to play her body like he already knew every inch of it, like he owned it. She had just had an orgasm, yet here he was, already building up the next one.

She felt him insert two fingers inside her and the sensation of his mouth and his fingers working together was almost too much for her. But it was when he replaced his fingers with his mouth, stabbing her with his tongue that Lily lost it, grabbed his head with one hand and started to buck her hips against him wantonly. Her other hand went to one of her breast, massaging it through her top and bra.

She knew she was close to coming again and that realisation made her release her grip on Scorpius hair.

"Scorp, stop," she moaned, opening her eyes again to look at him.

At hearing her words, Scorpius lifted his head from his feast and watched her curiously. Lily could also see a little concern in his eyes, afraid that he had done something wrong.

"I want to come with you inside me this time," she said, brushing her finger against his jaw.

Scorpius let out a little sigh of relief before making his way back up to her.

"How can I resist you when you say things like that?" he murmured in her ear before kissing her again.

Lily could taste herself on his lips and curiously liked that feeling. She moaned against his lips when he suddenly flipped them so that she was now on top of him, straddling him.

"It's your turn to work now, Lily," Scorpius told her, using her full name once more.

He was looking at her with such hunger in his gaze, such desire that Lily quickly overcame her shyness about this new position and let her instinct take over.

She caressed his chest with her hands, going up and down a few times, all the while watching the different emotions passing through his eyes. He liked watching her touch him, that much she could tell.

She moved her hips tentatively, feeling his erection rub against her entrance. She repeated the move once, twice before deciding that they had had enough foreplay for the night.

Not really sure if she was doing it right but with her desire for him pushing her, she used her hand to guide him and slowly took him in.

At first, she still felt a slight pain but her body quickly adapted itself to this new situation and she resumed pushing until Scorpius was fully inside her. Lily let out a small triumphant sigh and started moving above the Slytherin.

"You're so beautiful, riding me like that Lily," Scorpius said before his hands came to rest on Lily's hips, helping her to keep her rhythm and he straightened so that he was sitting with his chest against Lily's.

One of his hands went to her top and lifted the green fabric to showcase Lily's bra and chest. He then pulled on the bra to free one of her breasts, grabbing it with his palm and capturing her nipple in his mouth.

Lily's moaned was matched with one from Scorpius and she let her head fall back as she kept moving against him. She felt the waves of pleasure grow inside her and she knew she was close. And apparently her attentive lover knew it too because he let go of her hips to slip his hand between them and started to rub her clit at the same time as his hips started to thrust inside her powerfully.

"Scorpius!" she shouted, undulating her hips uncontrollably, holding on to his shoulder and taking everything he was giving her.

"Fuck!" Scorpius cried out, pressing hard on her clit as his body started trembling against her.

Lily screamed his name long and hard as she shattered completely above him, her body shivering. And after a few last thrusts, Scorpius came with a groan, and reclined back on the bed, taking her with him.

When Scorpius woke up the next morning, he was only half surprised to find Lily gone from his bed. Apparently, she still had the ability to wake up early, even after a party and a good long night of sex. And what a night it had been. After that first explosive time, Lily had proven to be more than skilled for a few things during round 2 and she had been more than eager to go again when he had woken her around 4 am for round 3.

Yes, the little Gryffindor was more than just a quick learner, she was a natural. The alchemy between her and Scorpius was real and Scorpius was already thinking about the next time he could get the vixen in his bed.

With a sigh that was supposed to clear his head, Scorpius opened the curtains of his bed and took a look around the room. He checked that Lily hadn't forgotten any of her stuff and then focused on the four other beds. All the curtains were still closed, which meant that all 4 of his roommates were still sleeping and it also meant that none of them was sleeping alone.

Just like a magically locked door meant to knock before entering, closed curtains meant that the bed's owner was occupied. The curtains also helped to contain the silencing charms to the bed and create a perfectly soundproofed space for each of the beds. Which meant, that last night had been a good night for all 5 of the 7th year Slytherin.
