My Stepdaughter's Bestie

Part Five

I sent Chloe on her way not long after I finished with her last night. She had an excited spring in her step as she slipped on her panties and tiptoed out of my bedroom. I spent the rest of the night lying awake staring at the ceiling, wondering how I let that happen.

It's not like I had much of a say in it, after all. Chloe made sure of that when she sucked me off while it was still asleep. How is any man supposed to resist that?

But I guess I didn't have to fuck her...

I feel guilty, and I don't know what to do. There's a part of me that wants to tell Carol what happened, let her know that it was out of my control. Of course, she'll never believe that. Would she believe it if I told her there was a part of me that didn't want to sleep with the sexy college girl staying at my house?

Absolutely not.

It would be the end of our marriage if she found out. I can't let that happen.

It took a little bit of time, but I eventually fell asleep. Now, with the alarm of blaring at 6:00 a.m., I feel dead inside. With what happened last night, I should feel invigorated, but it's only weighing me down.

"Get up," Carol says, groggly nudging me. "We want to make sure we get a good spot."

I'm wide awake when she touches me and I have to pretend to be sleepily waking up like I do every morning. She can't know anything is wrong.

Carol drags herself out of bed and I linger in it while she starts a shower. I could join her and we could speed up our morning, but I'm all too aware of Chloe's scent still lingering on my skin. Instead, I go to the kitchen and start a pot of coffee while she's getting ready.

The girls are still sound asleep in their room, so I have a few minutes worry-free without having to deal with what happened last night.

Carol comes down dressed in a pair of denim shorts and her bikini top tied under one of my old band t-shirts she likes to steal. Normally, seeing her like this would have me all over her, but I can't bring myself to do that right now. She looks hot as hell right now, but knowing not even 8 hours ago every inch of my cock was shoved inside of Chloe holds me back.

I hand her a cup of coffee then run to go shower, being quick about it before slipping on a pair of swim trunks and a plain white T-shirt. By the time I'm out of the shower, I hear the front door opening and I brace myself for a day with Pauline.

I wouldn't say my sister-in-law is awful, but I wouldn't say she's good. She has a lot of great qualities and the two of us have gotten to know each other a little bit since Carol and I got married. But Pauline has always thought there was something off about me. I never knew why because I truly do love Carol and I had never hurt her before.

But I know if she goes digging around today she might just find something. I've got to steer clear of her at all costs.

"Marky-Mark!" Pauline says, pulling me in for a hug when she sees me. I hug her and wrap an arm around her shoulder as I guide her to the patio outside. On nice summer days Carol and I always like to take our coffee outside in the morning. Carol is only a few feet behind us carrying the coffee carafe and a tray of mugs and pastries.

"So I heard you and Carl aren't together anymore," I say, hoping it'll divert the attention away from me and give her the space to talk about herself. Lord knows she likes talking about herself. "I'm sorry to hear that. I know you and him were planning for the future."

Pauline shakes her head, rolling her eyes dramatically as she sips her coffee. "Good riddance. If only I could have opened my eyes sooner and saw what a pig the man was."

"Pig?" I ask, raising an eyebrow and grabbing a Danish. Carol tosses me a nervous glance and I am about to open my mouth to tell Pauline she doesn't have to elaborate.

"A filthy, no good, disgusting, pig." Pauline grits her teeth as she speaks and I can only imagine what Carl did to get this level of anger from her.

"I'll go wake the girls," Carol says, awkwardly excusing herself and leaving me alone with her sister.

"Please don't feel like you have to elaborate on my behalf," I say, though I am somewhat intrigued.

"You're bound to find out eventually, you might as well hear it from my lips," Pauline sighs. "His computer was logged in one day and he was getting a bunch of notifications, and I saw a FetLife account where he was basically looking for a harem. As it turns out, he managed to find one and once a month for the past year he's been meeting up with five women in Cincinnati to live out their fantasies."

Oh my god.

"Five women?" I ask, my jaw practically on the floor.

I feel a twinge of guilt in my chest knowing that I'm currently lying to my own wife and taking the moral high ground with Carl, granted I'm only dealing with one woman. I can't imagine trying to juggle five women at one time. Though, I can understand it might be worth it for the perks.

"The girl said they'll be ready in about 20 minutes," Carol says, coming back outside to join us.

Pauline rants some more about all the ways Carl wronged her in their relationship and how she's planning on taking him to court for money he owes her. The entire time I just watch Carol and her sister talk about this, seeing how angry Carol is on Pauline's behalf.

If I don't play my cards right, this conversation is going to be happening once again with the cards reversed, Carol talking about how much she hates me and how she's going to take me for everything in our divorce.

The girls wander out eventually wearing bikinis that make my mouth water and small, see-through cover-ups around their waists. Both of them smile and wave, Leah going over and giving Pauline a big hug as she introduces Chloe.

I do my best to avoid looking at her as I focus on my coffee and danish. It's almost impossible.

The girls don't usually drink coffee, so they just opt to skip breakfast and help us load the car with everything we'll need for the day. Pauline decided to bring a bunch of supplies for herself, and with all of the beach chairs, bags, floaties, and miscellaneous other supplies we might need just in case, the car is packed. The last thing we have to fit is a cooler filled with ice and bottles of water, sandwiches, and soft drinks.

"Need a hand, Marky?" Pauline taunts behind me as I try playing Tetris with all of the supplies in the trunk of her crossover.

"I got it," I grunt, trying to lift the heavy cooler and set it on top of a stack of beach chairs, but when it starts falling I quickly pull it off and set it on the ground.

"Why don't we just put that in the back seat?" Carol asks, opening it up and taking a look at the space.

"Where are all three of us going to sit?" I ask, walking over and gesturing to the limited space.

"It'll only be less than two hours, you guys can squeeze together," Carol says, shrugging her shoulders. "Besides, you're driving on the way back so there will be plenty more space back here and we can empty the cooler so we can store things more effectively."

The girls, both eager to get on the road and make it to the beach, promptly climb in and I try to sit the cooler between both of them. It's a tight squeeze and eventually, Chloe slides one leg between both of mine and falls back on me with an exasperated sigh.

"How about we just ride like this?" Chloe asks, looking at everyone else in the car.

I want to say no and push her off of me because this has to end. Without even looking at her face, I know exactly what she's thinking. This is going to be hell if she's riding on my lap this whole time.

"Looks like we've got it all figured out," Carol says, closing the door on all three of us and climbing in the passenger seat herself.

I feel eyes on my face and I look to my right to see Leah staring at us with a smirk. Why couldn't Chloe have just sat on her lap? It would have been a lot less weird if that were the case.

Chloe's barely been on my lap for a minute and a half and the blood is already rushing from my head. I close my eyes and turn toward the window, willing myself to think about anything other than the hot, sexy girl sitting on my lap wearing next to nothing.

We take off and pulling out of the driveway and getting onto the road is a little bumpy. With every bump, Chloe bounces on my lap and it only excites me more.

She shuffles in the seat, trying to get comfortable, but I see her reaching for the back of the cover up she's wearing, lifting it just enough for there to be one less layer of fabric between her pussy and my cock.

Leah can't see what's happening because there's a cooler between us, and the only person who would have a visual of anything would be my wife, which is the worst case scenario.

The air conditioner is blasting and after a few minutes, Chloe remarks about how cold it is and Carol grabs a towel from a bag she has up front with her and hands it to Chloe. Chloe drapes it over her legs, wrapping it around her waist just enough that I can see how I'm obscured from my wife.

A shiver of excitement rushes through me as Chloe readjust herself on my lap, grinding her pussy directly against my rapidly inflating cock. I continue staring out the window, biting me inside of my cheek to keep from moaning.

I can't say or do anything about this right now. If I do, it'll draw attention to what's happening back here and questions will be asked that I don't want to answer. So, I just let Chloe do what she's doing. She moves her hips against me gently, rubbing her pussy against my hard cock, teasing it more and more with every movement.

Even though there's a part of me that doesn't want this to be happening, it's so fucking hot. I'm sitting in a car with my wife, sister-in-law, and stepdaughter and this hot college girl is grinding herself against me, making me hard and teasing me right in front of all of their eyes.

None of them suspect anything is happening over here.

Leah's head is pressed against the glass and she's sleeping, Pauline and Carol are in the front seat chatting about what Pauline plans on doing now that she and Carl are broken up.

I get to just sit here, looking down at the ass of this hot college girl as she teases her own clit against me.

After a while, I can't take it anymore. I feel dizzy, like all common sense has completely abandoned my brain because of the lust Chloe has driven out of me. I lower my hands and slowly inch them under the towel, reaching around to feel the front of her bikini bottoms. She's definitely wet for me.

I massage her, watching as she bites her lip and tries to stay quiet while I bring her tiny jolts of pleasure in the car. My cock is throbbing under her and with every movement I get closer to cumming.

I know it's fucked up, but I want to cum right now. I'm so fucking hard and she's only making things worse.

I move my hand from her panties, wanting to find a way to relieve myself right now, knowing I'm not going to be able to take it much longer. This has been going on for the duration of the car ride and it's been about an hour, so soon enough we're going to be parking and getting out of the car and I can't very well have a massive hard on while I'm doing that. I've got to take care of it before we arrive.

"I hate this song so much," I say to Chloe, looking at her with lust heavy in my eyes. "Would you mind leaning forward and changing the station?"

Chloe stares at me, winks and flashes me a devious smile. She does exactly as I ask, her ass raising off of me just enough to see the little wet spot on her panties before I slide the bottom aside to expose her bare pussy. In another swift-motion, I nervously pull my cock out, looking at my sleeping stepdaughter beside me to make sure she doesn't see.

I position it right outside of Chloe's wet hole and as soon as she feels me, she lowers herself on it.

It takes all the restraint in my body not to let out a loud moan as soon as her walls clamp around me. My hands are still under the towel and I reach around to massage her clit with one of my hands, feeling how she shakes against me.

I can't very well fuck her right now because the motions are going to be quite obvious, but I can fully stuff myself inside of her. If I make her cum by rubbing her clit, there's a part of me that thinks her own pussy tightening around me might be just enough to get me to cum inside of her.

Chloe has something else in mind, apparently. She spreads her legs a little wider and I feel her subtly moving her hips back and forth, pumping my cock in and out of her ever so slowly. She does this while I massage her clit with my finger, not able to hold herself back from the brink of orgasm.

We've got about an hour left on the drive, and a part of me wants to take my time. Being inside of her pussy feels like heaven and right now, I don't care about anything else. I pull my finger away from her clit and she looks over her shoulder at me with disappointment in her eyes.

"Not now," I mouth to her, smiling as I grip her waist and hold her against me.

We sit like this for a few minutes, my cock fully sheathed inside of her while the motion of the road occasionally drives tiny jolts of electricity through us. The longer I'm inside of her, the more wet she gets. Feeling how her tight pussy holds me, keeping my cock warm inside of her, only turns me on more.

Every so often I massage her clit, bringing her closer to the brink of orgasm, feeling how her walls clench around me as she almost gets there. She wants it desperately, too. I always pull away just before I send her over the edge.

When we're about 15 minutes away from the beach, I know we have to finish. I grip her waist with my hands to try to keep her steady as possible, lifting her off of my cock just enough so I can pump myself inside of her.

I feel her breath quickening and she tries her best to stay relatively normal as I let every inch of my cock fill her before pulling half of it out and shoving it back in.

The crappy road does wonders to help us. Whenever there is a pothole or a speed bump, I can fully ram myself inside of her without repercussions. Soon enough, I'm in rhythm with the road as I fuck her from below, letting my cock stretch her tight little pussy.

Chloe looks out the window, craning her neck to stare at me as she bites her lip hard when she finally comes. Just as I suspected, feeling how her pussy grips me is all I need to be sent over the edge. I cum inside of her, my cock twitching and spurting as I fill her with every drop of my seed.

She pretends to look out the window while she stares in my eye the entire time. My fingernails dig into her waist as I pulled her steady and fully fuck her from below while surrounded by other people in the car.

When I finally finish, she doesn't move off of me to let me put my cock back in my pants. Instead she sits on me like she doesn't want my cock out of her ever. I don't want that either.

We park in the parking lot of the beach, everyone excited to get out and stretch their legs after a 2-hour drive. Chloe climbs off of me, quickly covering her pussy with the bottom of her bikini to avoid cum dripping out of her. Honestly, I should have thought about that possible repercussion before fucking her, and now that there's a chance she's going to walk to the beach with cum dripping down her leg I'm filled with worry.

Thankfully it looks like the bikini bottoms are tight enough, hugging her curves with the express purpose of keeping them on while water breaks around her, so that we don't have to worry.

I put my cock away and let Chloe slide off my lap.

Carol, Pauline, and Leah walk ahead of us with light chairs and bags with beach towels in tow. They leave me behind with the keys and the cooler to lift it out and carry it behind them.

"I'll be right back, I forgot my bag," Chloe says, backing away from all of them as they keep their attention trained on the beach, pointing to the perfect location they want to go. Chloe runs away from them, tossing a quick glance over her shoulder before leaning in and giving me a quick, sloppy kiss.

My eyes are open and I look over her shoulder to make sure my wife is still looking at the beach. Thankfully, she is. I kiss Chloe back, tasting every inch of her mouth with my tongue.

"I just can't get enough of your cock," Chloe whispers, pulling her mouth away from me and reaching around my waist to grab her bag from the floor of the car. She lets her finger graze against my soft dick before pulling away. "We'll have to find some time to get away together today. I need to taste you again."

Before I can say anything she turns around with her bag and hand, jogging to catch up with the other woman. As much as I hate to admit it, I want that too. Knowing that my wife is going to be on the beach with her sister, sneaking away and fucking Chloe for the third time in 24 hours is all I need.

I don't think I can fight this anymore.
