My Stepdaughter's Bestie

Part One

"So how long is she going to be staying here again?" I ask Carol as she pours far too much coffee in her thermos to jet out of the house.

"August? Not too sure when Leah said school is starting back up," she replies with a casual shrug.

I nod my head and bite back a sigh. I barely know Carol's daughter, Leah. Now I'm expected to be home all summer with Leah and her friend Chloe. They're both in college and coming back to stay here for a few months over the summer. I think Leah is 19 or 20, so I'm only double her age. I'm sure there won't be a major generational gap that will make conversing with her incredibly awkward.

"Remind me why she isn't staying at her parent's place?" I continue as I follow Carol to the door.

"Leah didn't give me the whole story, it's private, apparently. But Chloe's home life isn't great and Leah offered for her to stay," Carol says with a sigh. "Can I go to work now?"

I kiss her on the cheek, slap her butt, and watch her walk out the door to her car.

When I married Carol last year, I knew she had a daughter. Carol only started dating because Leah went off to college and she was lonely at home. Well, she met me, and after a spontaneous trip to Vegas, we got married and now she's my emergency contact.

The last time I saw Leah was at Christmas. Even then, I barely saw her. I had to go out of town to cover New Year's Eve in Time's Square for the magazine and Carol wanted to stay home and bond with her daughter. It was probably best with all the new changes in her life.

After going back inside and brewing a new pot of coffee (Carol has a serious caffeine addiction and drinks the entire pot), I get to work in my office going over features my editor wants me to write. Fashion trends for men, health trends for men, interviews with doctors about the dangers of prostate cancer. Just your typical men's health magazine content reiterated for the umpteenth time with a new name on the byline.

Gabe, my editor, emails me asking for features pitches and I lean back to think about some ideas. While I'm mid sentence typing a reply, I hear two car doors slam outside and loud laughter shortly after.

I exit out of the tab I'm in and prepare myself for small talk. When I get to the door and open it, I'm immediately blinded by the sun, but I wave in the direction of the noise anyway. Leah and Chloe are here and I need to make sure I'm being welcoming. That's what Carol reminded me to be seventeen times this morning, anyway.

"Hey girls," I call toward them, squinting through the blinding light.

"Mark, hi," Leah says, dropping her duffle bag on the ground as she approaches. I back up so the roof blocks the sun from my eyes and get a good look at Leah for the first time.

Now, the last time I saw her, she was bundled up in sweatpants and oversized Penn State hoodies. I recognized that she was a beautiful girl, but I didn't get to look at her like this.

Leah is... I'm a writer and I don't even have a proper word to describe her. My cock nearly springs to life seeing her in the tight bodysuit tanktop and miniskirt she's wearing. It's simultaneously effortless and casual, but so stylish that you could easily mistake her for a model fresh from the runway. It doesn't hurt that has an absolutely killer body, shown off by the tight clothes she's wearing.

Her blonde hair is tied back in a thick braid behind her, showing off her beautiful face with a few strands falling loose around it. Surprisingly, her eyes are brown. I've seen pictures of Carol's ex so I know Leah must've gotten that from him because Carol's eyes are baby blue.

"Hey, Mark," Leah says, standing in front of me with a grin. She hesitates before deciding to give me the kind of awkward half hug reserved for occasions like this. "I guess Mom's working?"

Suffice to say, I have no clue where to put my hands. I'd love to reach around and cup her tight ass, but that might not be the greeting she's expecting.

"She wanted to be here but she couldn't get out of work," I reply.

I'm so distracted by Leah's... everything that I almost forget about Chloe entirely. Then she moves up to stand by Leah and it feels like the wind has been knocked out of me.

Chloe is just as stunning as Leah. Bright blue eyes, pale skin, dark lips, and straight black hair hanging midway down her back. She's shorter than Leah, with a slimmer build, but her breasts are almost bursting out of the little white tank top she's wearing.

Chloe smiles, offering me a shy wave. There's an immediate glimmer in her eyes that I know means trouble. I've seen it before. Countless women in bars, at conferences, you name it. It makes my heart skip a beat and I feel like a weight is pulling my eyes to her chest.

I'm immediately struck by the guilt of thinking my new stepdaughter's best friend is lusting after me. I mean, even ignoring the fact that I'm a married man, it's wildly inappropriate to be thinking about either of these girls like this. Especially Leah.

It's not lost on me that it makes it all the more exciting.

"You must be Chloe," I say, holding a hand out to shake hers. She just smiles and nods.

There's an awkward moment of silence where my brain is completely empty. What do I even say to these girls? These girls aren't even old enough to buy beer yet and I'm pushing 45. What do people their age talk about?

"How was the drive?" I ask, nearly wincing. I focus on grabbing the bag Leah set down and guiding them inside.

"Long. Exhausting," Leah says with a little laugh. "Honestly, both of us just want to crash for a while."

"Understandable," I say, almost relieved to not have to make small talk. There's a bit of disappointment in my gut knowing I won't be looking at them for a while, though.

I have to mentally remind myself about Carol. My beautiful wife who I love and shouldn't be thinking of her daughter this way.

But Chloe's harder to shake. There isn't that line with her to make it even more inappropriate. Sure, she's young. But I see girls like her on Instagram all the time and I've definitely imagined what it would be like to fuck them. With Chloe, it's kind of the same.

At least, that's what I'm telling myself.

"Fridge is stocked. Your mom went shopping last night and got all your favorites," I say as I drop the bag on the floor in the living room. Chloe shoves her hands in the pockets of her denim shorts.

"Bless her," Leah laughs.

"This is a beautiful house," Chloe says as she looks around. "I'd love to take some photos of it this summer while I'm here."

"You're into photography?" I ask.

"Yeah, I love it. It's what I study at school, actually," Chloe replies with a smile. She tucks some of her hair behind her ear and I have to fight the little flicker of adoration in my chest.

"I'd love to see some of your work sometime. I'm a bit of an amateur, myself." Chloe perks up and takes a tiny step toward me. I can see the excitement in her eyes and that same glimmer of attraction I saw at the door comes back.

My phone buzzes in my pocket and I know right away it's Gabe needing me for something. I pull it out and my worst fears are confirmed. "You girls get settled in. I have to run back to work, but I'll see you around later."

"It was nice meeting you!" Chloe says with a little bounce that makes her tits shake in a way I will be thinking about later.

I rush back to the office for a quick chat with Gabe before he sends over a new article I need to write asap, breaking news for the website about a celebrity's rebound with a popstar. Truly riveting stuff.

When I'm done and have it sent in for edits I lean back and run my fingers through my hair. The sound of doors opening and closing catches my attention and I'm alerted to the fact that Leah and Chloe are here all over again.

Listening to the footsteps, it sounds like someone went from the bathroom then back to Leah's room. It's been hours since they left to go lay down for a while and rest after their drive.

When the footsteps are gone, and I can walk around the house without risk of running into either of them, I get up to go to the bathroom myself. Listen, it's not that I don't want to see them. But right now, my mind is all over the place. Two sexy young college girls just came to live in my house and I'm here all alone. Can you really blame me?

Leah's door is cracked open and I don't think much of it at first, but when I get closer I freeze. I hadn't thought about their sleeping arrangements before this. I never really thought they'd be sharing a bed.

But now, seeing them on one full size bed with arms draped around each other, my mind can't help itself. It's not any easier with both of them wearing nothing but tank tops and flowy pajama shorts that show much more of their tight young asses than I should be seeing right now.

I lick my lips, feeling how my cock strains against my pants watching them. Two sexy, young college girls in one bed, facing each other as they hold each other close. I have to wonder about what else these two might have done in bed together.

Chloe's hand is on Leah's lower back, if she were to lower it just a few inches she'd be touching Leah's tight young ass. God, I want to see that. My cock is hard at the thought and before I think any better of it, my hand is in my pocket readjusting myself. I squeeze my cock gently through the fabric, feeling the exhilaration of being caught at any moment. I let out a quiet sigh before freezing, my entire body tense.

Chloe shuffles in bed, letting out a sleepy little moan as she nestles against the pillow. I wasn't loud, but there's a chance she's a super light sleeper and I just woke her up. I take a step back and hide, knowing these two can't see me here. That's the worst case scenario for me.

After a moment, I don't hear any noise and I take a cautious step forward, my blood pumping in my veins. I tell myself that I need to keep walking, go to the bathroom and forget all about this. But the temptation to look is too strong.

I glance into the room and my heart nearly stops beating. Chloe's no longer on her side with a hand draped over Leah's side. She's on her back, with her tanktop lifted up just enough for me to see a little bit of underboob. Her hand is on her stomach and slowly moving upward, like she's teasing me in her sleep.

It eventually lands between her breasts, hiding just under the fabric like she's going to push her top up even more and show me her perfect tits. I'm waiting for it too. I'd give anything to see it.

Before Chloe even has a chance, Leah shuffles in her sleep, leaning closer and resting an arm over Chloe. It lands on her bare stomach, caressing her and making its way toward her breasts.

My cock is leaking as Chloe moves her hand aside and Leah's replaces it.

"You're so naughty," Leah whispers, barely audible to be as she nuzzles closer and moves her hand underneath Chloe's shirt. She's fully rubbing Chloe's nipple. My cock is aching and it's taking everything in me not to pull it out and jack off to some live girl on girl action right now.

Neither of them seem to notice me, so I could probably get away from it.

Chloe laughs under her breath and moans, biting her lip. "I'm the naughty one? Looks to me like you're the one feeling me up."

"Can you blame me?" Leah says with a laugh. My heart comes to a complete stop when Leah sits up, pushes Chloe's tank top up all the way to free her large, pillowy breasts entirely. I nearly gasp, but I'm quiet. This is a dream. It has to be. How could any man ever get so lucky to see this? "Waking up to your sexy body is a massive turn on."

I can't believe my ears, my eyes for that matter, either. I can't believe any of this. Leah, my stepdaughter, has her hand on her best friends pink nipple and--

Oh. My. God.

Leah leans closer and flicks her tongue over the swollen bud. My cock is unignorably hard, standing straight up against me. I bite my lip hard while I grip it in my hand watching this.

Chloe moans and spreads her legs wider. She pushes hair out of Leah's face while she watches my stepdaughter suck her nipple.

"You're such a tease," Chloe says in a breathless little moan. "I know you're not even gonna get me off after this."

"You know I like it when you wait," Leah purrs before wrapping her lips around the nipple and sucks with a moan. Chloe arches her back and gasps, shaking from the pleasure.

"How long do I need to wait today?" Chloe desperately asks.

Leah pulls her mouth away, staring at Chloe as she lowers her tank top back to cover her now wet breast. "I'll make you cum soon, I promise."

I'm clearing my fucking schedule if this is happening tonight.

Both of them sit up and stretch, clearly no longer sleepy.

Chloe stands up and turns toward the door. That's my cue to leave. Even though that was the sexiest thing I've ever seen with my own eyes, they can't know I was here.

I tip toe back to my office and sit down in my chair. I take a few breaths to try and calm down. Yeah, I was a little hesitant about this summer at first, but if I can expect more of that I'm thrilled.

I don't even think. I immediately go on Amazon and look for small hidden cameras.

Okay, maybe that's pervy. But god damn... to be a fly on that wall.

Honestly, standing there and watching was half the fun. Just the idea of sneaking into Leah's room and hiding a camera makes my cock twitch.

After some research, I land on a few small cameras and buy them. Next day delivery is a beautiful thing.

The back door closes and I look through my window to see the two girls sitting on the porch swing each with a beer in hand. I should reprimand them for drinking without permission. But after that show I have no room to bring up the "permission" argument.

My cock is still semi hard staring at them out there. They've changed clothes now, both wearing tight shorts and t-shirts.

I get up to pee, realizing I haven't actually gone since the show. As I walk by their room, I start feeling wrong about my recent Amazon transaction. When I get to the bathroom, I pull the phone out and go to my order to cancel it.

Before I do, I spot something on the floor. A small pair of white cotton panties just in front of the empty laundry hamper.

I pick it up, looking closely enough to see a wet stain on them. Whose are these?

Honestly, it doesn't matter. The idea of either of those sexy girls wearing these panties, making each other wet with them, is such a turn on.

I ball them up and shove them in my pocket.

Peeing is hard with my massive erection, but I make it happen.

When I go back to my office I pull the panties out and don't spare a moment inhaling the delicious scent of one of these babe's pussy. It smells like absolute heaven and I lick my lips, pulling my cock out.

I pump cock furiously as I sniff the panties, letting my tongue lap at the wetness in an attempt to taste this delicious pussy juice.

Laughter outside catches my attention and I turn around, excited by the idea of jacking off while watching the girls. I lean back in my chair so they can't see me, dropping the wet panties to my throbbing cock and rubbing the fabric against it.

Leah and Chloe are sitting close to each other by the pool now, their shirts taken off to show them in their tiny little bathing suit tops. I could nearly cum from the visual alone.

I tease the tip of my cock, imagining them both on their knees in front of me, lapping at it with their tongues.

"Fuck me," I moan when Leah pushes Chloe's hair aside and kisses her.

It's not a quick, passionless kiss. Both of them are into it, mouths open, tongues sliding in and out of each other's mouths. Leah's hand lands between Chloe's legs and she rubs her pussy through the shorts. Chloe pulls away from the kiss and moans as Leah presses her lips between her breasts.

She lowers the cup of her bikini and sucks her nipple with an eager smile, her hand moving faster between Chloe's legs. My cock is so hard I could cum without even touching it. I bring myself right to the edge and stop, watching eagerly as Leah's hand moves inside Chloe's shorts.

Chloe runs her fingers through Leah's hair and moans, eyes closed and experiencing ecstasy while my stepdaughter fingers her tight little pussy.

I watch as Chloe cums. Her whole body shakes and she bites her lip hard, legs spread wide as Leah's hand moves faster and faster, her mouth never leaving Chloe's tit.

I let go, feeling my cock stiffen and throb, cum exploding all over the little white panties. I let out a guttural moan I didn't even know I could make. It's loud, too. I'm just glad they're outside and hopefully far enough away not to hear it.

When I'm done, balls drained of cum, Leah pulls her finger from Chloe's wet pussy and licks it.

God damn... these girls are naughty.

If this was just a taste of what's in store between them, I have to see more. I feel terrible for not cancelling the Amazon order, but what's the harm in just looking? I just know these girls are gonna put on a hell of a show for me, whether they know it or not.
