So this is definitely a lemon, another ominous October prompt about flannel sheets.

Perhaps she had a bit of the perverse in her, but one of Hermione's favorite things about the season changes and incoming cold weather was the change of bedding in her bedroom. Unlike what her friends always thought when they were in school together, she never used Gryffindor colors in her bedroom, preferring, instead, the cool and calming tones of her Slytherin husband's house colors. Of course, just to tweak at his own sense of acceptability, she also used plaid patterns. In her opinion, all flannel should really come in plaid, or even tartan if one felt so inclined. And so, every fall, she would bring out her favorite green and silver plaid flannel sheets from the cedar storage chest she lovingly tucked them into at the end of winter.

Humming softly to herself, she directed the fitted sheet into place on their queen sized bed with her wand, not wanting to waste her time fighting with the damn thing like she had as a teenager. It was a testament to her years of practice that the entire process only took a few seconds before she started on placing the flat sheet. Her eyes slid shut as she held the sheet to her nose, breathing deeply to enjoy the warm woody scent left behind from the cedar chest. It reminded her of her husband's own particular scent. Cedar, bergamont, and various herbal notes that tickled her senses. It was funny how easily the scent of freshly unpacked sheets would make her belly coil with need and bring forth visions of her husband's beautiful pale skin in contrast against them. This visceral response always led to her carefully dressing in a new lingerie set before artfully arranging her body across the bed. True, he could time this particular part of their intimacy with unerring accuracy because, as sure as the weather turned cold, Hermione Snape would be scantily clad and waiting for him in their bed on top of fresh flannel sheets.

As always, his presence was announced with a soft whisper of wool and the feel of his onyx eyes roving down her body. Hermione's lips curved into an inviting smile, her own whiskey hued gaze tracking the movements of his long fingers gracefully loosening the buttons traveling down the long lines of his tall form. No matter how many times she watched him remove his layers of clothing, it always struck her as decadently erotic with each button undone to reveal his lean muscled body. And she always enjoyed the play of light across his ivory toned skin.

Her tongue darted out to wet her lips in anticipation and she noted the way her husband's coal colored eyes became hooded while a lazy half smirk twitched one corner of his mouth upwards. The rest of her body responded immediately to that very male expression. Slick wetness gathering between her thighs, breasts feeling heavy and sensitive, a slight hitch in her breathing, and gods…she could feel her cheeks flushing with both arousal and the shy blush that always seemed to steal across her face whenever he found her dressed provocatively. At least this time her knickers, whilst extremely unsubstantial and likely shouldn't even be categorized as such, might actually survive the encounter. Though, judging by the way his hands twitched when she shifted forward to kneel on the bed, she rather doubted they would make it any longer than the others. Pity really, she had spent a lot of time picking out this particular set of knickers and bra.

Severus Snape considered himself a lucky man most days. He even had a smug sense of enjoyment in knowing that he had survived the war and even surpassed expectations by fully embracing Hermione's shy, yet adorably bold, advances after her Arithmancy apprenticeship ended. Yes, he was aware that no one expected him to reciprocate and true, he also knew that it enraged the youngest Weasley boy when they ran into the red-head in public. Interestingly, he found his wife to be the more vindictive one in their relationship. And wasn't that the sexiest thing he'd seen? Well, perhaps not as sublimely wonderful as her yearly ritual involving the fall sheet change she insisted on. For eleven years now, he looked forward to coming home and seeing what sort of new surprise she would have wrapped around her delectable body. This year it appeared that she wanted to completely blow his mind. He hadn't been aware that the entire back and crotch could be cut out of knickers and still be classified as such. More like an overpriced window dressing with potential.

Not that he was complaining. Nope, he and his cock were in total agreement that his wife should be wearing that style of knickers more often and perhaps he would order some more. A rainbow of them if necessary. His lips tugged upwards in a slow, sensual, smile as he moved onto the bed with his wife. He could clearly see her pulse fluttering in her neck and the way her pupils dilated with excitement.

Fuck, he adored this woman.

Careful maneuvering of his body against hers allowed for him to loom over her scantily clad form while he captured her hands above her head. Pressing against Hermione so intimately, even without penetration, was a heady experience. Warm, lush, inviting, and her magic rolling against his body in an indulgent sweep of barely restrained power. How any man had missed out on this amazing woman…it was mind boggling. But, one fool's blunder was his victory and he intended to spend the rest of their lives celebrating that victory in every manner she allowed.

Hermione's lips found her husband's in a heated kiss, the smooth caress of his tongue against her own causing her hips to roll upwards in response. She loved the taste of his mouth, like dark chocolate and the faint hint of his favorite tea. But then his hands moved, sliding slowly down her arms with a gentle tickle of his fingertips and her skin prickled with anticipation. One of her legs worked over his thigh and leveraged her hips upwards. She could feel the hard press of his cock against her inner thigh and rolled her hips once more. Between the heat of his body and the soft warmth of her favorite sheets, she was more than ready to have him just take her. Not that he did such things often as he preferred drawing out their pleasure whenever possible.

A low chuckle spilled from Severus' lips at his wife's impatience. It didn't take much for him to realize she had gotten herself over stimulated while she waited for him to get home. He had considered a slow teasing progression of events. Licking and nibbling his way down her body. Teasing and worshiping her cunt with his tongue. The sweet taste of her release filling his mouth,driving his ardor higher. Perhaps he would indulge them both later.

His arms slid beneath her body, cradling her back whilst his hands gripped her shoulders to hold her in place. One teasing drag of his cock against her slick folds was enough to have her wriggling wantonly, a low whine teasing from her throat. His hips surged forward, the head of his cock piercing her easily until he was buried deep inside of her tight heat. He loved the way she gasped and dug her nails into his back.

Hermione shifted, her feet dropping flat against the bed so she could angle her hips upwards and meet his next thrust at full force. Her body sang in response. There, the heavy press of his cock against her g-spot had her half shrieking in pleasure. It still amazed her how easily her husband brought her to peak. And then, oh! Again and again the blunt head of his cock hit that spongy place until she was almost in tears. Then he moved and her toes were pointed at the ceiling, her knees hooked over his shoulders.

"Oh fuck!" She was bent double now, her own shoulders digging into the mattress with the force of her husband's thrusts. Her fingers twisted in the sheets as she wound tighter and tighter, her body on the cusp of release.

Severus groaned and pulled out of her, ignoring her murmured protest as he tilted her hips up further, bringing her thighs along his shoulders to bury his face in her cunt. Fuck she tasted as fantastic as always. Running the flat of his tongue from her soaked opening to her clit, he was rewarded with a sharp cry from her throat. Absolutely amazing. He swirled his tongue around her clit again and drew it gently between his teeth before sucking hard.

"Oh fuck! Fuck! Fucking fuck me Severus!" Hermione's vision nearly went black from the strength of her orgasm rushing through her body. She felt his cock impale her again and whimpered as the act triggered a smaller but no less intense secondary orgasm.

Jaw clenched, he pounded into his wife, harder and harder until, with a harsh cry, his balls tightened and his cum spilled against her cervix in hot bursts. He let her legs fall on either side of his hips and leaned forward to kiss her flushed chest, her name a soft murmur of gratification against her skin. Still buried inside of her, he could feel her tight channel rhythmically spasming around his cock, milking every last drop from him. Planting soft kisses along her jaw to her ear, he gently nipped at her earlobe. "I love sheet change day, wife."
