Seeing the look on Sirius's face was well worth the trip to the Room of Requirement. He was shocked that there existed this whole room that he had never even heard of before, and then bemoaned the loss of the Marauder's Map into Filch's grubby hands.
The room had really outdone itself. A large fire was blazing in the fireplace, filling the room with a cheerful roar. A large window revealed the thunderstorm that was raging outside, serving to only make the room feel cozier. Two tall bookshelves flanked either side of the mantle, which was topped with a large mirror, and a large white bearskin rug was laid out on the floor. On the opposite side of the room there was a large bed topped with crimson and gold damask covers.
It was perfect. It was something like out of one of the romance novels that she had found at the Burrow, set in the Scottish Highlands. She just hoped that Sirius was up for ravishing her.
Sirius hadn't blushed at the intent of the room, but rather looked at her with passionate eyes, his pupils dilating, never leaving her face. "This is a very nice room you've been hiding from me, kitten," he said.
Hermione was helpless and she watched his tongue dart out to wet his lips, in what she figured was anticipation.
"Why would you drag me off to the boys' dorms when we could have come here?" he asked.
Hermione smiled. "Well, leaving the common room would have been a little bit conspicuous. And, I have the admit the...danger of getting caught was a little bit exciting," she answered.
"You minx," Sirius whispered.
She thought he meant it to rile her up, but really it only had her longing to be held by him. He took two steps forward to close the distance between them. His kiss was insistent and his lips were firm and fit against her so perfectly. Hermione sighed into his embrace, wrapping her arms around his waist. When he nibbled along her bottom lip, she could think of no other recourse than to nibble his pouty lower lip back.
Sirius groaned and pushed his hands up into her hair. He pulled out pin after pin and Hermione pulled her lips away as Lily's gorgeous charms work was destroyed. "Sirius!" she whined. "That took Lily ages!"
"What? I missed seeing your hair all wild like you've just been fucked," he countered. He grabbed some of her hair and pulled so that she was forced to look up into his gray eyes. "I have wanted to tangle my hands in it all night."
Hermione made a low keening sound as his dirty words instantly sent a heat pooling in her belly. Desperate, she rubbed her thighs together to ease the newly formed ache. Sirius brought his lips to her neck, first peppering her hot skin with tantalizing kisses before latching onto her pulse point and sucking hard. When he was sure that he'd left his mark there, he released her fevered skin with a pop.
Hermione eagerly grabbed Sirius and brought his lips to hers, eager to kiss him once again. Without preamble, she thrust her tongue into his mouth, eager to pair and tangle with her mate. When she finally released him, she was panting for breath and rested her head on his chest. "I'm so dizzy," she whispered with tenderness.
"Well, let's get you to the bed then," he said. Sirius pushed her backwards with that infuriating smirk until she was tumbling onto the soft comforter.
Hermione pushed herself backwards until she was propped up against the multitude of pillows. Throwing him what she hoped was a seductive gaze, Hermione frowned when all that Sirius did was laugh at her.
"I am sorry, kitten," he said between laughs, "But with your fantastic plumage, you just look like a trussed up bird."
Hermione frowned. She hadn't thought about how her costume would work with romance. Quickly standing from the bed, she turned so that her back faced Sirius. "Well, help me unzip it then!" she whined, impatiently. Hermione felt him grab hold of the zipper and pull downwards, tracing her bare spine with his fingers as inch by inch of skin was revealed. Finally, the fabric and feathers fell to the floor and Hermione turned to face him.
The dress necessitated the lack of a bra, and she was aware that this was the first time he was seeing her mostly naked. She was a little self conscious, knowing that she was still growing into her body, and that her breasts were on the small side and that her limbs were still a bit gangly and that she was rather skinny so she didn't have much feminine softness.
But the look on Sirius's face melted away all of her worries. He stared at her like she was the most beautiful thing he'd seen. He cleared his throat. "I am feeling a bit overdressed."
His eyes still didn't leave her as she crawled on the bed towards him. When she reached his prone form, she immediately brought her lips to his and her fingers to the buttons on his ridiculous costume. She only broke the kiss to remove his shirt and undershirt, and she resumed kissing him when she brought her fingers to the waistband of his pants.
Once she'd freed his hips — blushing fiercely at feeling his hard erection straining to be touched by her hand — Sirius desperately wiggled and kicked until his pants were off and on the floor.
Suddenly unhappy with their positioning, Sirius flipped them so that he was looking down at her, his hips cradled delicately between her legs. He hissed at feeling how hot she was there and he could tell when he thrust against her that she was quite wet as well. Staring at her flushed face and swollen lips, she looked so gorgeous to him. He wasn't sure how many more times he would be able to do this with her before she went into hiding so he burned the memory of her face into his brain.
Leaving her panting, Sirius kissed the side of her neck again, peppering kisses further and further down her body until he was met with her breasts. He kissed all around a nipple until it was hard and straining for his touch. Instead of wrapping his lips around the tip, he turned and repeated the treatment to its twin. Hermione was rocking against him, clutching desperately at his shoulders and groaning in frustration when he moved further away from the nipple.
Grabbing him by the hair, Hermione pulled on his head until his mouth was positioned over the stiff peak. "Stop teasing me Sirius!" she whined.
Sirius gave the nipple a gentle nip between his teeth. "Bossy," he scolded with a smirk. Then he wrapped his lips around the tip of her breast, circling his tongue over the nipple again and again while Hermione moaned above him. He brought his hand up to the neglected breast, palming it roughly with his calloused hands before pinching her nipple again and again.
Hearing her moan his name quietly, and feeling her fingers grabbing at his hair had Sirius harder than he'd ever been. He wasn't sure what was so special about her, but he didn't think about it when she was guiding his mouth to the other breast. Once he'd given that breast equal treatment, he allowed a hand to slide down her side and into the waistband of her knickers, slowly tugging them down until they were at her ankles.
Hermione obliged, kicking her legs until they were free of the restrictive material. Sirius slithered further down between her legs, kissing her waist and navel until he was finally staring directly at her pussy. She knew that she should feel embarrassment, but his liquid silver eyes staring up at her face with such reverence only made her bite her lip in anticipation.
Sirius parted her folds with one hand and looked at her. "So beautiful, Hermione. And so, so wet." Unable to do anything but watch helplessly, Hermione was awash in sensation when his tongue extended and touched the little clit at the top of her sex. Sirius groaned in appreciation before licking a line from her slit to her clit, spreading some of her sweet moisture.
Hermione clamped her legs around his head once he began lapping at her in earnest. This was unlike anything she'd ever felt before and she never wanted it to stop. His tongue was really so talented, dipping into her cleft every now and again, leaving her wishing for more. When he finally entered her with one finger, he latched onto her clit, sucking it between his lips. Hermione was trying her best not to rock against his face. She was helpless as after one, two, three thrusts of his finger, she was coming so hard that she saw stars. Lying boneless on the bed, she tried not to shudder when Sirius sat up and wiped his mouth with the back of his hand.
After recovering for a moment, Hermione pushed Sirius back flat on his back and trailed her fingers down his sides into his boxers before pulling them down. His erection sprung free from its confines, hard for her. He was really quite muscular with just the beginnings of black chest hair between his pectorals. He was lean and hard and Merlin, she felt powerful, reducing this man to a puddle of lust — for her!
She reached down between their bodies, wrapping her hand around his cock, allowing him to thrust into her hand. She took note of his facial expressions, seeing where he liked to be touched and caressed, before deciding she wanted to do more. Although she was not a virgin, having had sex with Viktor Krum the summer previous, she had never attempted to give someone a blow job before, so she just hoped she didn't embarrass herself terribly.
Sticking her tongue out, she tentatively licked the tip of him, tentatively. Sirius's hips reflexively jerked towards her. Feeling a bit more confident she took the tip into her warm, wet mouth. She swirled her tongue around the head, noting that he particularly liked to have the underside lapped at. Sirius threaded his hands into her wild hair and gently pulled her further down onto his length until she gagged slightly.
"Sorry," Sirius whispered sheepishly, but Hermione just pulled off a little before taking him in her mouth once more. She used her hand to stimulate the rest of him that she couldn't capture with her mouth. Soon, his hands were tangled in her hair again, and they were working in unison as his cock thrust in and out of her mouth, Sirius groaning again and again and Hermione being a bit embarrassingly wet at the knowledge that she was giving him so much pleasure.
Soon, he was tugging her hair, pulling her off of him. "That was wonderful, but I would like to take things a bit further, if that's alright with you?" he asked, trying not to pressure her.
"Of course it's alright," Hermione grinned, before scrambling up his body. She pressed her wet core along the length of him while Sirius reached for his wand to cast a contraceptive charm. When he was done, Hermione reached between them and positioned him so that the tip of his cock was resting at her cleft. Then, with Sirius's hands guiding her hips, she sunk down inch by glorious inch.
Hermione took a moment to adjust to the feel of him inside her. Sirius reached out and rubbed her little nub in circles to help ease the ache. Hermione sighed, and before long she was thrusting back and forth against him. He seemed to know how to play her body like a fiddle, helping her glide up and down his hard cock so that she hit all the places that would make her sing. She couldn't help but call out his name.
Sirius was watching her rock back and forth on top of him, her small breasts bouncing slightly. Her eyes were screwed tightly shut and her mouth was open, sweetly calling his name. He could feel her walls clench desperately at him again and again, not wanting him to leave. When Hermione's slow and torturous pace was too much for him, he finally flipped her over so that he could take control of the thrusting.
He brought his lips down on hers, desperately melding their mouths together and swallowing up her moans. Her arms wrapped around his shoulders as he started to thrust into her as hard and as fast as he could. They were slowly sliding up the bed, but neither one could care when they were so close to completion.
Hermione wrenched her mouth away from his before chanting, "Please, Sirius" again and again until she finally came with a squeal, her ankles locking around his body to keep him close. Once Sirius felt her clench tightly around him in orgasm, he was gone as well, surging deep within her only a few more times. Sirius collapsed on top of her, his hard body melding with her soft one, but Hermione couldn't care about the heavy weight of him.
Once he caught his breath, he rolled over laying next to her. They were both sweaty and cooling off rapidly. Hermione was beautiful in her afterglow, flushed and chest heaving. He listened to her heavy breathing, closing his eyes, before slowly drifting off to sleep.
Hermione turned on her side to look at him. Once she was absolutely sure he was asleep, she let the tears come to her eyes. She couldn't believe that she had to leave him after they had just shared that. She had decided to leave without saying goodbye, thinking that a clean break would be easier for everyone. But really, she was just a coward. She didn't want to leave this young man she had come to love, but she knew that she had to. And she couldn't face him with that on her mind.
Steeling herself, she stood from the bed and slid back into her knickers and shimmied the dress back up over her hips before zipping the back of the dress. Surrounded in blue satin and multi colored plumage didn't make her feel any stronger, though.
She reached into her little bag and pulled out the letter, placing it on the pillow next to Sirius. She hoped he wouldn't be too angry. Hermione knew that Professor Dumbledore said she mustn't meddle with time, but she figured she could do this little bit to help Harry. She hoped that he would forgive her, in time.
Taking one last look at her favorite animagus, Hermione turned and left the Room of Requirement.
