Genevieve licked her lips, dipping one toe into the water and straightening up again. She walked over to the bathroom door, making sure the lock was placed.
Her parents, well her mother and her stepfather, had gone away for the weekend, leaving Genevieve and her stepbrother Mark to fend for themselves. Mark was cool, he was old enough to buy booze for nineteen-year-old Genevieve and her friends and didn't complain much when Genevieve chose a rom-com over his action/adventure choices.
Lately, especially since Mark had started community college on the other side of town, Genevieve felt his eyes lingering on her a little too long. When it was her turn to wash the dishes, he'd brush against her near the sink, using the excuse of wanting to grab a glass for water. He was bumping into her all the time, and "forgetting" to knock on her bedroom door, simply bursting in when Genevieve least expected it. Mark and Genevieve had known each other for about eight years, so Genevieve wasn't sure where this sudden touchiness had come from.
Her friends teased her, taunting Genevieve that Mark had set his eyes on her. They were making bets on when he'd finally put the moves on her, which grossed Genevieve out to no end. They were practically siblings. Besides, Genevieve had a boyfriend, and Mark had just started going out with some girl from his class.
Genevieve thought about Mark as she washed herself, hearing the thud of the front door that announced his arrival. She quickly got out of the bath and dried her body, wrapping the thick cotton towel around her curvy body and taking a deep breath before throwing the door open to go to her room. Her boyfriend David was coming in about two hours for a date to the movies. She would have a snack and then get ready.
Genevieve didn't hear Mark as she walked down the stairs, so she assumed he was in his room. She thought of David, and how he'd surely bring up the topic of sex once more. Since they'd reached their one year anniversary, David had been all over Genevieve for not sleeping with him. But she was waiting for the right time, although David never seemed to understand that.
Genevieve tugged down the shorts she'd changed into, stretching her arms as she kept the towel from falling off her head. Exasperated, she unwrapped it and shook her hair out, nearly colliding with Mark, who had a very obvious look of guilt on his face. "Hey." Mark didn't look her in the eye as he climbed up the stairs. It was odd considering Mark was extremely social. Genevieve walked on to the kitchen, grabbing a banana from the fruit bowl and standing near the sink looking out the window while she ate.
Footsteps announced Mark's arrival once more, and he wandered into the kitchen, having changed into a sleeveless shirt. "How was school?" Genevieve asked brightly. Mark looked at her somberly, grabbing an apple and biting into it. He brushed past her and threw the cupboard open, grabbing a glass and filling it from the fridge's water dispenser. "Whatever." She huffed, turning to look out the window. Mark shoved her aside and turned on the sink to wash his hands. Genevieve stood still, hearing Mark step out of the kitchen Weird.
She finished the banana and was stepping outside the kitchen when a pair of arms wrapped around her from behind. She jumped, struggling under the strong grasp. "I'm tired of this." Mark muttered into her ear. "How was school Gen? Terrible, because I broke up with my girlfriend and you know why?"
"Mark, let go of me! I swear to god if you don't let go I'll"-
"I broke up with her because all I've been thinking about for the past two years is fucking the shit out of you."
Genevieve felt her stomach drop, her yells becoming shriller as she twisted underneath her stepbrother's hold. "Mark stop, this isn't funny! It's gross, please let me go upstairs, I have a date with David in half an hour."
It seemed like Mark was talking to himself. "All this time I've just been seeing you walking around in those short shorts and those little nighties. All for me right?" Genevieve smelled beer in his breath. She jerked around, opening her mouth to scream. His hand clamped down over her mouth and she tried to bite it, but he quickly hoisted her over his shoulder. He wasn't overly muscular, but playing basketball and going to the gym kept his frame lean. Nevermind the fact he towered over her.
"Mark you had too much to drink, please. You'll regret whatever you're doing, soon." Genevieve felt tears of frustration prick her eyes as Mark groped onto the back of her thighs and began shuffling towards the stairs.
"One beer hardly counts as anything. Besides, do you think I'd want to be wasted now that I finally have the chance to fuck that tight little body of yours?"
"Mark! I- Unf!-" Mark took an over exaggerated step up, kneeing Genevieve on the stomach as he did so. She gasped, feeling a throbbing pain where his knee had hit. That shut her up for about thirty seconds, giving Mark time to reach the top of the stairs and start heading towards his bedroom.
"Who do you think encouraged your mom and my dad to take the trip down to Napa they'd been wanting so much? Just needed to give them that big brother bullshit and they were all over it. And the idea that your mom is out there laughing and drinking wine while I'm screwing the shit out of her daughter is making me so hard." Mark kicked open the door to his bedroom, tossing Genevieve down over the bed like she didn't weigh anything. He kicked the door shut and stood over a dazed Genevieve, who quickly tried to scramble up. He shoved her back, making her head thud against the wall and black circles dance across her vision.
"Mark, please, please. You don't have to do this." Genevive's voice trembled, her hands struggling to tug her shorts down and keep her clothing in place.
"Oh Gen. Genny. You're right, I don't have to," he grabbed onto his mound through the fabric of his shorts, "I want to. And you better just start undressing yourself now or else. You choose, I either fuck the shit out of you and make you enjoy it, or fuck the shit out of you and make you never want to have physical contact with another human again. Either or, I'm still going to be inside of you."
Genevieve began to cry then, panicked sobs making her chest ache and her fingers still holding her shorts up. Her stepbrother stood over her, still holding onto his member through the fabric. "Please, please. I've never done this before, I don't want to do it. We're supposed to be family."
"I was hoping you'd say that. The virgin part, I don't give two shits about the family. Your mom married my dad, but you and I, we just live together. Although I am a little surprised, Genny, you always acted as if you were so experienced when it came to sex. The hot cool girl who was too good for everyone else. I was disappointed when you showed up with that prick you call your boyfriend, but just knowing he hasn't gotten a single use out of that tight ass pussy of yours makes me incredibly happy."
He reached up to take off his shirt and she used that as an opportunity to kick him in the stomach. Mark reacted quickly, yanking her foot and pulling her leg forward so sharply a dull crack rang out in the room. Genevieve began to scream, hoping the neighbors would hear. Mark brought his hand across her face hard, and used her stunned silence to turn her on her stomach and put her hands behind her back, dodging her futile kicks. Genevieve felt the fabric he tied around her wrists, and finally around her feet.
Genevieve's screams started up again but not for long, as Mark put a pair of rolled up briefs in her mouth. "Enough." He said loudly, making Gen flinch. He stood her up and balanced her, all tied up and gagged. His hands ran up her thighs, pushing her shorts up. His finger brushed against her underwear, and quickly he pulled her shorts down.
Genevieve shook her head frantically, trying to reason with her stepbrother. "Look at that black lacy thing. God, you were planning to get laid tonight weren't you?" Mark laughed dryly, shoving Gen back onto the bed. The way she was all tied up now and unable to move at all made him harder. "You choose sis. Suck my cock, let me fuck your tits first, or shall we just go straight for the cunt? I am keeping you in mind, considering this is your first time. And don't you worry, I definitely will not be using a condom." Genevieve was crying, her strangled sobs making her body tremble. And her tits shake, which was all Mark was looking at. "I'm going to let you speak but just try and scream and you'll see where that gets you." He looked at her. "I'll fuck you painfully and make sure I cum in you so much there's no way you can't get pregnant." That made Genevieve's tears freeze from pure shock, her eyes getting wide and shaking her head quickly.
Mark reached up and took the briefs out of her mouth. Genevieve made no noise, complying. "That's a good sis. Alright, since it is your first time and I'm trying to make you enjoy this as well, I'll start off by eating you out." David didn't eat her out because he said Gen wouldn't like it as much as when he was inside of her, and that it would basically be pointless to do so. But Genevieve definitely didn't want her first oral experience to be with her stepbrother.
"Mark, please." Genevieve's pleads were ignored as Mark pulled down her underwear without much effort, sticking his mouth right over her cunt. He blew over it, his warm breath making Genevieve's skin tingle. He grabbed onto her thighs and shoved his tongue inside of Genevieve, lapping at the inside of her tunnel like a starved animal. Genevieve on instinct kept trying to squeeze her thighs together, but Mark held them down with force, never easing up on his tongue's assault. Genevieve still cried silently as the tightening in her stomach grew. When Mark flicked his tongue over Genevieve's clit, the tingling grew stronger. It was like the entire lower half of her body was vibrating, and Genevieve cried even harder from frustration. She wasn't enjoying Mark's attack, but her body was working against her.
"God you taste so fucking good. Jesus." Mark stuck his tongue even further inside of her. A moan escaped from Genevieve's mouth, and she hated it. She bit into her closed fist, feeling her legs shake and the feeling in her stomach intensify.
