Stepbrother Desire (Erotica)

Earlier that evening, just after Mike had left for his date with Emily, Sarah was in the washroom, starting yet another pile of her laundry. She heard a noise behind her and turned, seeing her younger sister Beth.

“Hey,” she said, turning back to her washer. “What’s up?”

Beth was quiet for a minute. She cleared her throat and tried to speak, but the words came out all jumbled. She sighed and rubbed a hand across her forehead in embarrassment. “So, I was wondering something.”

Sarah turned and glanced at her again. “Huh? Whats wrong?” she asked. Beth didn’t reply. “Bethy, just tell me whats wrong.”

Beth cleared her throat nervously. “I’m experiencing… I’m…”

“It’s okay Beth, just tell me.”

Beth nodded. “I’m horny,” she blurted.

Sarah burst into loud laughter.

“Thanks for being sensitive about it,” Beth said, slightly miffed.

Sarah raised her hand as Beth started to leave and grabbed her arm. She tried to catch her breath and stop laughing.

“I’m sorry, Bethy,” she said between giggles. “Please don’t leave, I’m sorry.”

Beth stood with her hands on her hips. She didn’t look amused.

“I’m so sorry, honey,” Sarah said. “I just… after the last time in here you were so deliberate, so direct about what you wanted. You were the last one I expected to be shy about being horny.”

“This is all pretty new to me. I get so worked up, and it seems like something else just takes me over. When that happens I’m not shy, and I know exactly what to say and exactly what to do to turn Mike on. But it’s different at other times. I still get horny but… I’m trying to deal with it by learning how to…”she hesitated.

“How to what, sugar?”

“Mtherate,” Beth mumbled.

“What?” Sarah asked, leaning closer.

“MASTURBATE,” Beth said finally, way louder than she had intended.Upstodatee from Novel(D)ra/m/a.O(r)g

Sarah began to laugh again, but not nearly as loudly or as long as the previous time. “I’m sorry, baby. I just couldn’t hear you.”

Beth was flushed. She turned around and began to leave.

“Honey, don’t go,” Sarah said. “I’ll be glad to show you how to get yourself off, but you don’t need to do that, you have other options you know.”

Beth nodded. “I know. I just figured with Mike not remembering what was going on, it might be best if we didn’t get too frisky when he’s around. I didn’t want to, you know… impose, either. I figured you were busy.”

“Aww, honey,” Sarah said, pulling Beth close enough for a hug. “I’m never THAT busy, and besides, even if I was, Emma is probably just as horny as you are. She IS Mike’s twin, you know.”

Beth giggled at that, and the embarrassment in the atmosphere was broken. She raised her head and looked directly at Sarah, an intense look in her eyes.

“Whoa,” Sarah said, seeing something different in Beth’s eyes. “You just got… taken over… didn’t you.”

Beth grinned and grabbed both of Sarah’s arms. “It’s like this incredibly persuasive little nymphomaniac in my head has taken over and I know exactly what to do. Maybe I have a split personality.”

As she finished speaking, Beth turned her slightly shorter sister around forcefully and pushed her forewards, grinning as she banged into the washer.

“Whoa, Bethy,” Sarah said, a shocked look in her eyes. A grin found its way to her lips as Beth came forwards, something else in her eyes. She tried to turn but Beth was right behind her. Sarah felt her sister’s hands moving around to the front of the old t-shirt she was wearing and in one swift motion Beth pulled it off and threw it to the floor. “Oh my… ” Sarah murmured.

A low growl of lust came from Beth’s throat as she grabbed the Sarah’s bra and pulled it down off her shoulders to her waist, exposing her breasts.

“Oh dear,” Sarah said as Beth spun her around and began to kiss up and down her neck. Sarah was wearing lounging pants, but they were quickly pulled down as her possessed younger sister ripped them downwards and to her ankles. Beth dropped to her knees quickly and peered upwards, kissing Sarah’s thigh, and moving towards her neatly trimmed pussy. “I thought… oh dear!… that you were the one that… oh!… needed release,” Sarah gasped.

“I told you, something just takes over. I was planning on doing myself, and now, you’ve… “offered” yourself to me, my inner slut just took over my plans. Don’t worry though, I’ll make you get me off before we’re done.” Beth grabbed one of Sarah’s legs and thew it over her shoulder, spreading the other girl’s pussy open. “Tell me if Slutty Beth is a good pussy eater,” she said, and slowly pushed her tongue into her older sister.

“Oh my god,” Sarah said, and glanced down, pulling her own brownish hair back as she did so, seeing Beth’s blonde locks cascading around her head as it bobbed slightly, her younger sister’s warm tongue exploring her depths. “Oh, shit…” she gasped.

“I’m guessing that’s a good thing,” Beth said quickly, before pushing her tongue back in.

“Fuck yes,” Sarah said, gasping and trying to remain standing. Her breath was coming in ragged gasps. “God, that’s the best anyone has ever eaten my pussy,” she said, almost too loudly. “Holy shit, Bethy,” Sarah groaned, one hand covering her face, the other latched onto a handful of Beth’s hair, Beth’s tongue pulsing against her clitoris and alternating back to her slit.

“Atta girl,” Beth said, feeling Sarah’s hand pushing her head deeper between her legs.

“OH MY GOD,” Sarah shouted, an orgasm slamming into her, wave after wave of pleasure crashing down. “I can’t… I can’t…” she tried to say, and finally her unsupported knee gave out and she began to fall towards the floor. Beth caught her however and lifted her physically smaller sister up, and set her on the dryer, before placing her tongue back where it had been. “Holy shit, Bethy,” Sarah said, when she was finally able to breathe again. “What the fuck got into you?”

Beth grinned and raised her head from between Sarah’s legs. “Nothing yet,” she said, and pulled Sarah from her spot on the dryer. “I’ll let you decide what to put in me though,” she said, a wicked grin on her face. Grabbing Sarah’s arms, she spun them both around and kissed her deeply on her lips, Sarah still trying to catch her breath.

“Fuck, you are… possessed!” Sarah said, breaking away for a second.

“I can try and turn it off,” Beth said, both fingers hooked in the tops of her spaghetti strap top.

Sarah smirked at her and shook her head. “You better not, you little temptress. I can be just as aggressive,” she said with a grin. Grabbing Beth’s top, Sarah yanked it down, revealing Beth’s pert nipples and heavenly breasts. Grinning, Beth began to wiggle out of her shorts, and soon they had dropped to the ground, followed quickly by her panties. Grabbing a handful of Sarah’s hair, she forced her to her knees and pushed her blonde haired pussy closer.

Sarah looked up and grinned as Beth forced her face deeply into her waiting cunt. “Eat it,” Beth growled crudely. Sarah looked up defiantly and shook her head.
