Erica growled in frustration, kicking her blankets to the foot of her bed as she tossed and turned. She was feeling restless and couldn't seem to get comfortable 'Maybe some fresh, cool air will help' she decided to herself as she stood up and made her way to her bedroom window. Half way to the window, she nervously paused for a moment she had only pair of panties on. Her pale, milky breasts were completely uncovered, and the idea of walking in front of a window in such a state made her pause. Only for a few moments, though. It was dark enough out that no one would see her. Finishing her short journey to the window, Erica stood in front of it for a moment, licking her dry lips. Grabbing the bottom of the frame, she slid it all the way up. The witch gasped quietly as she did so, the cool evening air feeling delightful against her warm skin. Her small pink nipples began to harden due to the chilly breeze, but Erica stood still, revelling in the feeling of her public toplessness. Licking her lips again, she made her way back to her bed. Her pussy was tingling lightly, and she was beginning to feel horny, she laid back down on her bed, not bothering to pull her blanket up from where she had kicked it off. Hooking her thumbs under the waistband of her underwear, she lifted her hips and slowly began to slide her panties off. Once she had slid them down her thighs and to her knees though, she paused, chewing her lip gently. Standing in front of the window wearing nothing but her panties was a huge turn-on, she had realized and what if someone had seen her 'Perhaps you are thinking about a certain potion teacher and what he would have done if he saw you like that' said a little voice inside her head. The more she thought about Severus accidentally seeing her topless, the hornier it made her, and the witch was getting hornier by the second. Severus would have punished her for the fact that she was going to touch herself, something he had banned her from doing " your orgasms belong to me, and if i ever found out that you touched yourself …" Those words he had said to her before she returned to Privet Drive for the summer holidays. But Severus wasn't here ' what he doesn't know wouldn't hurt him …' Erica though grinning to herself, and pulled her panties back up, giving her pussy an affectionate pat through the cotton of her underwear once her panties were snugly back in place. Bringing her hand up to her face, Erica slid a pair of fingers into her mouth, swirling her delicate tongue around them as she gently sucked at the two digits. Sliding the fingers out of her mouth with a wet smack of her lips, Erica brought her hand down to her breast, cupping the soft flesh with her dry fingers. Bringing her two wet fingers to her nipple, she rubbed it gently, coating it in her rapidly cooling spit imagining they were Severus's fingers. Erica let out a quiet moan as she felt her pussy dampening. Her free hand began to make its way to her panties, but she stopped it as soon as she realized what it was doing. Instead, Erica began tracing random patterns on her skin with her finger. She continued to massage her breast with her other hand while her free one explored her stomach. Bringing her two wet fingers back to her mouth, Erica again applied a copious coating of saliva to them. Dropping her hand back to her breast, she began to massage the milky flesh, smearing it with her spit as she did so. The young girl's idle hand had made its way dangerously close to her pussy again, though this time she was gently rubbing and tickling the inside of her thighs, teasing herself but never actually touching her increasingly gooey cunt. Her panties were beginning to soak through now, a small, dark patch of dampness visible in the crotch of her underwear. It was getting more and more difficult to keep her fingers away from her slit, but she was resolved to enjoy herself as much as possible that evening instead of just bringing herself to a quick orgasm as she usually did. Erica continued to massage her breast with one hand while she teased herself with the other one, and after a few minutes she was growing very wet. Bringing her hand to her pussy, Erica cupped it gently through her panties, moaning in delight as she felt her wetness through her underwear. Slowly, teasingly, she slid her fingertips under the elastic waistband as she played with the nipple of her other breast. She continued to slide her hand downwards, stopping just shy of her wet slit. Instead she continued to tease herself, rubbing her mound but never touching her wet lips. The horny girl moaned happily as she rubbed her smooth skin, delighted at the complete lack of hair. Her pubic hair had grown in very lightly, but Severus loved a bald pussy, so he took care to remove the small amount of hair that had grown. Horny as hell now from her teasing, Erica finally decided it was time to relent. Her fingers quickly slid over her pussy, and she moaned at the feeling of wetness that was quickly coating her hand. The crotch of her panties were completely soaked through by now, and the smell of her slimy, slippery honey was beginning to become noticeable in the air. She traced a pair of fingers up and down her slick slit for a few seconds before sliding them between her gooey lips and fingering herself. She moaned loudly as she did so imagining Severus's fingers teasing her pussy, not caring if anyone could hear her through her open bedroom window. Erica began to pant for air, chest gently heaving as she continued to play with her breasts. Her panting seemed quiet, though, next to the sound her fingers were making. Her pussy didn't seem content to merely be soaking wet, judging by how the flow of her warm, wet arousal seemed to be increasing with each gooey plunge of her fingers. "Fuck yes, Severus! Harder, faster … nnnnghhhh." she cried, enjoying the mess she was making of her panties. Erica felt her orgasm approaching quickly, and decided to change pace to keep it from coming too soon. Pulling her soaked hand out of her soaked panties, she rolled over onto her stomach. She got onto her knees, lifting her ass up into the air but keeping her chest against the bed. Tilting her head to the side so that her face wasn't buried into her pillow, the horny witch brought her slimy hand up to her face. Her hand was completely coated in her pussy's wet horniness. Bringing her clean hand up to her pussy, she slid it under the waistband of her dripping underwear. Instead of stopping her hand to play with her slick slit this time, though, Erica brought it to her ass, and quickly began rubbing her asshole with a pair of fingers. Finding the position she was in a bit awkward and uncomfortable, she brought her fingers away from her ass and to her pussy for a moment. She fingered her dripping cunt for a few quick seconds, pulling her hand out of her panties once the two fingers were sufficiently coated with her juices. This time she slid her hand down the back of her panties. Bringing her two fingers back to her ass, she again began to rub her hole, this time slicking it with her wetness. When Severus fucked her at Hogwarts he had only taken her cunt, but some times she had fantasized about him raping her ass mercilessly, and that thought turned her on even more though she never told Severus. As she did this Erica stuck out her tongue and slowly licked one of the fingers of her other hand clean. Erica moaned loudly as she did so, loving the taste of her own pussy on her fingers. Too horny to help herself, the girl quickly slid the two fingers into her ass. She was shocked at the loud, girlish moan of delight that escaped her lips as she fingered her ass, but quickly decided she didn't want to be quiet before taking another lick of her pussy-soaked hand and crying out even louder.
Self control breaking down, Erica's fingers began to slide in and out of her ass faster and faster. Tasting herself while she fingered her ass seemed to be bringing her close, quick, though, so she continued to lick her juices off her hand in between feminine cries of pleasure. After just a few short minutes her orgasm hit, sending electric shocks sparking throughout her feminine body. Her ears were barely registering her loud cries of pure delight, and she wasn't sure what she was actually saying. Her already soaked pussy erupted, gushing hot torrents of sticky cum into her undies. Her wetness quickly began to flow down her creamy white thighs as her panties failed to contain her squirting orgasm. Once her orgasm began to subside, Erica collapsed down on her bed. She gulped down lungfuls of fresh air as the cool breeze began to chill her blazing hot skin. Sweat dripped down her curves, and her waist and thighs were completely soaked due to her profuse orgasm. She licked her dry lips as she continued to pant, causing her milky tits to jiggle lightly with each bounce of her chest, Erica sighed contentedly as she drifted off to sleep.
Erica was sleeping soundly in her bed; unaware that the window she opened to cool her room from the day's summer heat was an invitation for a sexual encounter. Unaware of the hand that carefully pulled it open further, just enough to slip inside and loom over her. She was unaware that Snape had watched her masturbate, had watched her sleep for agonizing he reached for her, she woke slowly, eyes opening heavily and reluctantly. She felt a hand over her mouth to muffle her startled gasp. Snape's body crushed her while his other hand slipped between them, with the help of his knees, to part her tangled legs. A whimper from her did nothing to soften Snape's cold gaze as he pushed his finger into her body. Erica tensed for a minute and then relaxed. Her eyes now opened wide as Snape's fingers stopped. " Please Sir …" she whispered, and Severus smirked "Please what, Slut?" Erica wrapped her legs around his waist and her arms around his shoulders " I want your cock inside of me … now …" she begged looking into Snape's black eyes . In one heartless thrust, his cock was inside her. Erica gasped from the abruptness, from the ache of the stretch. Severus didn't allow any time for her to become acquainted with his girth. He plunged into Erica again and again, watching her. Tears seeped from the corners of her eyes and slid down past her temples into the canals of her ears. Erica widened her legs and pushed up to meet his violent thrusts. Once, twice, and then she came, shaking and jerking. Her moans muffled wetly against his shoulder. Severus smirked " how naughty are you my slut … touching yourself without permission and thinking you could get away with it, now… how should i punish you ? A spanking? orgasm denial?" Severus seemed to think about something and his expression became even more cruel, Erica gulped " Sir …" but Severus slapped her ass " i didn't give you permission to talk slut, i know the perfect punishment for you … You know? I couldn't help but notice that you were fingering your ass before, and you came hard when you did … Tell me Slut, do you want me to rape your delicious ass? You want my cock to pour it mercilessly while i insult and humiliate you … What would your loving relatives think if they saw you fucked from behind by your teacher?" At the mention of her Aunt and Uncle the arousal Erica was feeling evaporated, a look of utter terror replaced the lust on her face " no please … they would…" she stopped herself in time and felt Tears threaten to fall down her eyes. Severus watched her suddenly worried, why at the mention of her relatives Erica became terrorized? He had never meant to make good on the threat to make her relatives watch her being fucked, he had hoped to arouse her even more, but her expression suggested something else " Eri… Potter … what is it? Potter?" Severus was growing worried but Erica didn't seem to hear him " Professor … you should go now before they wake …" Erica seemed almost scared. Severus tensed " Potter you don't order me around and think … mmmmmmhhhhfff!" Erica covered his mouth and looked at the door thanking Merlin for the silencing charm she had put in her room that evening. Snape removed her hand from his mouth, then he rose tucking himself in his trousers and went to the door trying to open it but found it locked " Potter why did you lock yourself in your room?" Snape turned to the girl but her expression made him freeze " it's locked from outside…" she whispered as tears were sliding along her cheeks. Severus sighed and then went to the open window and appareled away without saying a word, leaving the girl alone.
