Free Stepbrother With Benefits by Lana J. Swift

going to be an absolute mess!
     
    When that first rush of Mark’s seminal fluids petered out, Beth adjusted her fingers and flexed her pussy again, closing her eyes and shivering as a second load of cum was noisily expelled onto the apartment floor.
     
    Jack was literally stunned. Even during his own sex-crazed years at college, he’d never witnessed anyone doing anything like this before!
     
    Giving the stubby wings of her inner labia a quick flick to knock off the last clinging droplets of cum, Beth straightened up and smiled at Jack, shrugging her shoulders in mild amusement. “Heh... as you can see, Mark has the tendency to make a shitload of cum,” she commented casually, as though this were a typical morning event for her.
     
    The more Jack thought about it... maybe it was!
     
    From the other couch, Mark abruptly jumped up. “Gotta whizz!” he announced brusquely, giving Beth’s ass a loud smack before dashing off to the bathroom.
     
    Beth called after him in irritation. “Hey, what about me! The deal is we both fuckin’ get to get off, you selfish jerk!”
     
    Collapsing back on the couch, Beth raised her feet up onto the cushion and hugged her knees to her chest. With a frown on her face, she looked across at Jack.
     
    “Well, pooh. Now I’m gonna be horny all day.” Pointedly scanning Jack’s reclined, blanket-covered body, Beth suddenly got excited. “Hey, you wanna maybe help me take care of that?” she asked, brazenly spreading her legs and sliding her middle finger along her puffy slit. She dipped the tip inside her inflamed hole, and somehow there was still enough of Mark’s cum trapped inside for a small trickle to run tantalizingly over her asshole, before ultimately dripping onto the cushion.
     
    Suddenly, all of those mysterious stains on the couches made perfect sense!
     
    “I know from personal experience that sloppy seconds can be a lot of fun,” she said with a snicker, thrusting the penetrating finger and making wet, sticky sounds.
     
    See? This finger could be you, Jack!
     
    Even though Jack had never double-teamed a single girl before, his painfully engorged cock twitched violently at Beth’s kinky offer.
     
    Jack was certain that most any man his age would eagerly accept Beth’s offer without so much as a second thought. But, in his heart, he knew it could never be. For one, Ellie would surely disown him if she ever found out he’d slept with her best friend – and his stepsister was far too important to Jack for him to jeopardize their relationship over a mere moment of pleasure.
     
    Even if it would probably be a really good moment!
     
    “Uh, I don’t think so, Beth,” he replied with no small amount of regret.
     
    “Why? You turned gay or something?” She pulled the wet finger from her pussy and stuck it in her mouth, playfully sucking off its coating of cum and pussy juice.
     
    Jack groaned and scraped his fingernails across his stubbled cheek. Resisting her was taking a herculean effort! “No, Beth, I’m definitely not gay. Far from it. It’s just... it’s just kinda complicated.”
     
    “What could be so complicated? You’re a great guy, and I always did have something of a childhood crush on you... it’d be fun for us to finally hook up! Don’t you think so too?”
     
    Jack’s raging libido screamed at him to stop refusing such an appealing invitation, that there was no one in his life he would be cheating on... but for some reason his conscious simply wouldn’t allow him to give in. “Uh, really, thanks... but... I can’t. You’re a beautiful woman, Beth, and obviously very comfortable with your body and yourself...” He tried to think of a decent excuse that wouldn’t put the blame squarely on his sister. “...But, I feel like I’d be taking advantage of you.”
     
    “What?” she gasped. “Of course you wouldn’t! Geez, I just wanna get off before class, not marry you or something! What’s so complicated about
