My Stepdaughter's Bestie

Part Nine

I've hardly been able to look at Carol over the past few days. Every time I make eye contact with her all I can think about is how I've betrayed her in the worst possible way. Sleeping with a complete stranger or a co-worker is one thing, but fucking my wife's daughter is entirely different.

I can make an excuse for Chloe. Fucking my step daughter's best friend is nowhere near as bad as my actual stepdaughter.

Yet here I am.

I've had a threesome with both of them and I've fully fucked my stepdaughter, cumming inside of her. And the worst part is that I want to do it again. I want to do it again and again for the rest of my life because it was that fucking fantastic.

It was better than any sex I've ever had with Carol and I think that's where the root of my shame comes from. I married her, I swore a vow to her, yet here I am fantasizing about her daughter's mouth wrapped around my cock.

I need to end this. Right now, I'm not even talking about my relationship with Leah and Chloe. I mean my marriage.

How am I supposed to sleep in bed next to Carol knowing the things I've done? How am I supposed to sleep next to her when the only thing I'm thinking about is Chloe and Leah?

I just have to think of the reason. If I tell her the truth right now I'm going to go down in history as the biggest asshole on the face of the earth. I could lie and say that I fell out of love with her and leave it at that, but then there's Leah and her manipulation of the entire situation.

If I don't navigate the situation carefully enough, Leah could open her mouth and ruin everything for me. That's the last thing I need.

Despite everything I've done, I don't want Carol to be hurt. She truly is an angel of a woman and she doesn't deserve this.

I don't deserve her.

I've been waiting in my office all morning waiting for Carol to leave for work. I lied, which is becoming quite a habit of mine, and told her that I had an early morning meeting with my editor just to avoid her. She's been so preoccupied with everything going on with Pauline that she hasn't noticed me withdrawing yet. But I know it's only a matter of time.

The longer I sit in my office and think about what to do, the angrier I get. All of this has been nothing but a game to Leah. She brought Chloe here to mess with me and she has been getting inside my head ever since the two of them got here. It's cruel and it's borderline evil.

But at the same time, I know I'm just as guilty as Leah is, but that doesn't take away the anger I feel towards her.

I hear footsteps and chatting outside, assuming that it has to be Leah and Chloe moving around now that it's past ten in the morning and they've woken up. It takes me a few minutes to figure out what I'm going to say and work up the courage to actually confront them both.

Even though I want to continue this illicit affair with every fiber of my being, it has to stop. I would love to explore every inch of Leah and Chloe's bodies with my tongue, but it's already gone too far.

I find the two of them in the living room with their feet kicked up on the couch, both scrolling on Tik Tok on their phones. When I clear my throat, Leah looks up at me and sets her phone down with a smile.

"Mom's at work if you want to have some fun," Leah says, tossing her feet on the ground and staring up at me. The smile on her face is devious, filled with mischief and desire and it takes everything in me to look past that.

"No. I don't and we can never do this again," I say, crossing my arms in front of me as I look between both of them. "I know you're upset about your parents divorce and it seems like what they did was selfish to you, but you can't repay that with your own selfishness. What you're doing right now will destroy your mother."

"And this is all my fault?" Leah asks, standing up. The smile on her lips falls and I see a little irritation in her eyes. "It didn't take a lot of teasing for you to give in and start sleeping with Chloe. I think you will have broken my mother's heart just as much as me."

"Trust me, I know that. I fucked up and I'm going to do everything I can to make that right," I say, shaking my head. "I'm going to leave your mother."

"Really?" Chloe chimes in, standing up and staring at me with excitement behind her eyes. "Does Carol know that yet?"

I shake my head and run my fingers through my hair. Maybe it was a mistake telling the two of them this before Carol because the last thing I need is one of them slipping up and letting her know before I have a chance to.

"I haven't figured out how to do it yet. But I'm going to do it. Carol doesn't deserve to be treated the way she is right now." I take a deep breath and step toward Leah, locking my eyes on hers. "She doesn't deserve to be manipulated. I'm not going to let you break her heart the way you plan to."

Leah laughs and looks over her shoulder at Chloe, who surprisingly shows a bit of guilt in her eyes. "Mark, you've already done everything I needed you to do. You fucked Chloe like a thousand times and you came inside of me yesterday. You've already played your part. Why torture yourself by resisting us now?"

Leah steps forward and closes the gap between us so that she's barely an inch away from me. I feel the heat from her body swarming around me and I hate the way I react to it. Her breath is hot against my neck as she exhales and even through everything, I want more of it.

"I said I'm done and I mean it. I'm not some pawn you can move around on the chess board to get what you want," I say, trying to keep my face as stoic as possible as I look down at her. "We need to stop this now so I can end things amicably with your mother. If you tell her the truth, it will destroy her and you will regret that for the rest of your life. You only have one mother."

Leah rolls her eyes and turns her head to look at Chloe behind her, expecting her to back her up. Instead, Chloe shrugs her shoulders and looks down at the ground nervously.

"I mean, he has a point, Leah," Chloe timidly says. "I know I agreed to do this before I got here, but I don't want to hurt your mom either."

"I knew you would go soft on me," Leah says with an exaggerated sigh. She turns back to me with a blank look on her face. "Chloe's a little bit dickmatized."

I look over her shoulder at Chloe and see how she blushes and looks down at the ground. It's oddly sweet given the situation. Knowing everything I know now, Leah probably did manipulate things to get Chloe to act the way she did. Maybe Chloe is actually a sweet girl, but Leah definitely isn't.

"You're going to regret ending this." Leah takes a small step forward, her breasts now pressing against my chest. "You have two hot college girls here willing to do anything and everything to get you off and you're willing to end this. You're going to regret it for the rest of your life."

As unfortunate as it is, I know she's right.

Even standing in front of the two of them now and telling them I want to put an end to this is like torture. They've given me some of the most incredible sexual experiences I've ever had. Fucking Leah and Chloe has been a dream come true. If I didn't have a conscience, I'd continue. I wouldn't be able to stop.

"I know. It's been a lot of fun, but it has to end," I continue, holding my ground.

Leah licks her lips and looks me up and down slowly, the corners of her lips turning into a smile. She hooks a finger inside the waistband of my jeans and pulls me close enough that my groin is pressing against her stomach.

"Fine. We'll be over then. But how about we leave on a high note?" Leah asks, her hand moving from my waistband to massage the front of my jeans.

I reach down to stop her, but before I can my body reacts. Feeling my stepdaughter's hand massaging the rapidly inflating bulge in the front of my jeans is to erotic for me to turn down right away.

I know that I should, that I came out here to end things and so far it's been successful. But I've already gone far enough. How bad would one last time really be?

I don't push her away or back out of her grip. I let her hand explore the length of my cock through my jeans as her lips crash against my neck. I can't help the moan of satisfaction that creeps out of my mouth. I close my eyes and savor the feeling as Leah's fingers nimbly unbutton my jeans, pushing them to the ground alongside my briefs to free my hard cock.

I open my eyes to walk over to the couch, catching Chloe's eyes along the way. She's not getting involved the way Leah is and I'm a little bit disappointed. If I'm going to have one last time, I want to taste both of them.

"How about one last time with me later?" Chloe asks, smiling bashfully at me. "I kind of want you all to myself, I guess."

Leah stands in front of me and pushes her pajama shorts down before climbing on my lap. Her shirt is off a moment later, tossed onto the couch beside us so her breasts are completely exposed. I can no longer focus on Chloe and her question while my stepdaughter is straddling me completely naked.

"That sounds good," I say, not giving it much more thought. It's only fair, right?

Chloe walks out and heads to her room while Leah and I continue in the living room. I reach for her breasts, lowering my mouth to one and so I can her nipple between my lips. Her fingers run through my hair to hold me closer as I swirl my tongue around the peaked flesh.

"Oh yeah, Daddy, I'm going to miss this," Leah moans, grinding her pussy against me as she teases herself.

I growl against her as I continue sucking her nipples. My hands explore her body, slowly moving from her waist to her ass and gripping it tight as she grinds herself on me. Her body is so firm and nubile in my hands and the idea of never getting to feel this again is almost unimaginable right now.

I have to force thoughts of Carol far out of my mind so I can enjoy this. If it's going to be my last time with Leah, I want to enjoy it.

Her pussy is soaking wet as she grinds it against me and I can feel her juices against my cock already. I pull my mouth off of her breasts and stare at her and she gyrates on me, her eyes closed in pleasure. I reach my hand around and slide it between her legs and trace my fingers between her slick folds.

"How about you slide on my cock now?" I whisper, leaning back to enjoy the show as Leah opens her eyes and stares down at me with a grin. "Let Daddy feel your pussy stretching around him."

"Mmm." Leah licks her lips and does as I asked, her warm hands grabbing my cock to position it outside of her soaking wet hole. "Ahhh..." she moans while she slowly lowers herself on me.

"You feel so fucking good, baby," I say as her walls clamp down around me, already throbbing from her pleasure.

She wraps her arms around my neck to steady herself as she moves up and down. I look down at her perfect body, admiring the way her breasts bounce with every movement. She's absolutely perfect. Her hips buck against me and I look at her like she was made to take my cock.

I love fucking her way too much.

I grip her waist in my hand as she moves torturously slow, savoring every thrust of her hips against me. I watch as my cock slides in and out of her pussy, committing every second into my memory.

It's unfortunate that this has to end.

I slowly move a hand between her legs again and brush my thumb against her clit as she continues moving. As soon as I touch her, her eyes open and a loud moan escapes her throat. I lean forward and suck her nipple between my lips again as I tease her clit with my thumb.

"Oh my God!" Leah screams, bucking her hips faster against me as I force an orgasm out of her.

Her entire body trembles and her pussy tightens around me while she comes all over my cock. She whimpers in my ear and I just stare up at her with nothing but lust in my chest as I watch my step daughter in the throes of pleasure with my cock between her legs.

Her body twitches and she tries to move up and down my cock to drive more pleasure out, but she struggles through the waves of pleasure crashing over her. I grab her waist with my free hand and hold her in place as I pump my hips below her, meeting her halfway as she hovers above me.

Her breath is ragged and she digs her fingernails into the back of my neck as she pulls my face closer to suck her nipples some more. I tease it with my tongue, swirling it around the supple pink flush before teasing it gently with my teeth.

I'm close to cumming myself, but I hold back. If it's my last time with Leah, I want it to be fucking incredible.

Leah can hardly control herself as she comes and hearing every moan and whimper from her throat is so incredibly sexy. I wish I would have thought to record this in some way so I could relive this moment over and over for the rest of my life.

She finally calms down and lowers herself completely on my cock again when she feels that I'm still hard inside of her.

"Oh, Daddy, you make me feel so good," Leah says, running her hands up and down my chest before planting her lips online.

Her tongue fills my mouth and she moans as she grinds herself against me, still slowly and delicately moving her hips to get me to cum.

"I love hearing you come, baby," I whisper when she pulls away. My hands are back on her ass, squeezing it and spreading her cheeks apart while she moves up and down me.

"I want you to fill me with your cum," Leah whispers in my ear, gently licking the lobe before nibbling at it. She moans right in my ear and I let out a guttural groan hearing it. "Fuck me hard, Daddy..."

I push her away from me, staring down at her sexy body with my cock still between her legs before lifting her off and looking at her. "Get on the floor. Hands and knees," I say.

Leah smirks and does as I say, getting on her knees and bending over with her palms flat against the carpet. She looks over her shoulder so she arches her back and lowers her face so it's resting on the back of her hands.

Looking at her now, her ass is on full display for me. My cock is rock hard and it's not going to take much for me to explode inside of her now. Every moment that passes where my hard cock is not buried inside of her is like torture, so I put myself out of my misery and shove every inch of it inside of her hard and fast.

Leah screams when she takes me inside her. Her pussy quickly adjusts to me being inside it again and when I look down, Leah is breathing raggedly as she bites her lip hard.

I grab her waist with both of my hands and push her ass away from me, watching as my cock frees itself from her tight pussy. Then I slam myself inside of her again.

"Fuck yes!" Leah screams, whimpering already.

I did that again and again as I continuously thrust hard inside of her. I savor every whimper and moan that escapes her mouth as she screams and nearly cries from the pleasure.

My cock hardens inside her with every thrust and before I know it, I'm throbbing as cum spurts from the tip. Leah whimpers and cries out as she clamps down around me some more, milking every drop of cum from my balls as I continue thrusting in and out of her.

Both of us moan and savor every moment of our orgasms as we ride them out together.

When we're done, I pull out of my stepdaughter's pussy and watch as she collapses on the ground, her body spent and tired after that.

I'm about to open my mouth to remind her that was the last time, that is going to have to carry both of us a long time, when I hear the Ring doorbell app chime on my phone.

I quickly reach for my jeans on the ground and dig in the pocket to grab my phone. I find it and open the app as fast as I can, seeing a live video of Carol standing at the door and digging for her keys in her purse.

"Fuck, get dressed," I say, quickly putting on my pants and trying to clean up any obvious signs the two of us were just fucking.

I look down and see Leah hesitate on the ground. My heart sinks and I realize this is what she's wanted the whole time. She wanted Carol to catch me with her. Catching me with her means getting what she wanted all along.

Leah hesitates and I know that I am very well might be fucked.
