"Ohhhh! FUUUUUUUCK! DON'T STOP!" Alex screams. "I'M... FUCKING... CUMMING!" she huffs, as her pussy clamps around my cock and I shoot her full of hot cum. Kylie continues to fondle my balls while we jerkily ride out our orgasms.

When I finally collapse on her cushiony tits and we both gasp for breath, Kylie's hand is still caressing my ass and balls. I barely notice Kristina leaving the room.

"You actually did it?" Lauren says, storming into the room ahead of Kristina. "You spanked his ass? I was kidding," she adds.

"I think he liked it," Kylie says.

"Did you like it?" Alex asks. Lauren is now inspecting my ass, running her hand over the warm surface.

"Yeww!" Lauren snaps her hand back. "You're still inside Alex's pussy." I smile as I disengage my spent cock and roll off of her.

"I should get cleaned up," I say, sitting up and scooting off the bed.

"But did you like it," Kristina asks, standing near the foot of the bed.

"I'll let you know when I try to sit down," I answer. "But yeah, it added an erotic element to it that was very different. It took a while to get into a rhythm. Did you notice a difference, Alex?"

"Oh yeah," she smiles. "You were pounding into me harder than I've been pounded. Each time I heard that slap, I knew you were plunging in deep and mashing my clit. I came hard!"

As I squeeze past Kristina, she touches my ass and kisses my cheek. I turn on the shower watch the girls from the bathroom doorway.

"You guys okay, calling it a night?" Lauren asks, "I think we're all about spent."

"I know I'm good," Alex says, swinging her shapely brown legs off the bed."

"Me too," Kylie says, approaching me with a smile. "Thanks, Brandon," she says, kissing me lightly on the lips. "My boyfriend gets nothing until he eats me through an orgasm like that."

"Tell him I'm sorry to have spoiled things for him," I smile.

"This!" I say, flipping over and displaying my fully erect cock like a flagpole.

"Oooo," Kristina says, leaning up on her knees. "Can I have it?" Without waiting for an answer, she swings her leg over, straddling my hard cock. Gripping it between her fingers, she positions it at the entrance to her recently deflowered pussy and lowers herself down.

Lauren is staring in disbelief as my cock glides easily into her tight, but very lubricated hole.

"You were slick enough for that?" Lauren asks as she sits mesmerized, her face just inches from our coupling.

"I've been wet all afternoon," Kristina says, settling down fully on my cock with her pussy lips mashing my pubic hair. "I've been hoping for a chance to do this again," she smiles. "Without the pain."

Her tight, hot cunt is indeed slick enough for my cock and it conforms snugly to the intruder, sending electrified pulses up and down my throbbing shaft. My hands reflexively go to her elongated nipples as she starts to rock her body up and down. Fuck! This is the tightest fucking pussy I've ever felt. Earlier when I took her virginity, I was too worried about hurting her to fully appreciate the pleasure of it.

I tweak her nipples and stare at the wide-eyed innocence on her face as she starts to ride me. Innocence? What the fuck! I grab her hips and stop her movements.

"Condom!" I say, looking at Lauren.

"I'll get it," she answers, rolling off the bed and running down the hall.

"Thanks," Kristina blushes. "I forgot." I lift her off of my cock as Lauren returns, tearing the package open.

"Not a good thing to forget," I admonish Kristina. She nods sheepishly.

Lauren has the package open and smiles at me as she rolls it down my slick pole. Kristina raises her body up and Lauren aligns my cock with her glistening pussy lips. She continues holding my cock between her thumb and her finger as Kristina slides down the length.

Lauren releases my cock and then looks like she doesn't know whether to stay or leave. I put my right arm around her and pull her against my side.

"Please stay," I whisper, running my hand down her back and gently squeezing her ass cheek. She just nods and lays her head in the crook of my arm. Kristina is picking up the rhythm and I use my left hand to again play with her small breasts. While I'm tweaking her left nipple, Lauren reaches up and does the same to her right one.

"I just don't want you to remove your other hand," she says, referring to the one that is fondling her ass. Fuck! My cock was hard already, cocooned inside Kristina's compact pussy but watching my sister play with her friend's nipple sends renewed blood surges straight to it.

"Ohhh! I knew it would feel good but not this good!" Kristina breathes, getting lost in the pleasure as she bounces on my cock and we tease her long, thick nipples. The whole bed is shaking and I don't know how much longer I'll hold out. I need to speed up her release.

Kristina only lives a few houses away and it takes us about five minutes to walk there. She unlocks the door and I go in with her until she has the lights on and feels safe.

"Brandon," she says, pulling me against her. "I know what you said about not getting hurt and I'm not expecting anything to change between us..." She kisses me long and hard. "But just so you know, if you just want to get laid you know where to find me."

"I may come looking, Kristina," I answer, honestly. "But you should be looking for guys closer to your own age." I kiss her again like a lover's reluctant goodbye and head home to find out what's going on with my sister.

Lauren is no longer naked, she's slipped on a man's dress shirt, buttoning the bottom two buttons and leaving most of her breasts exposed.

"I cleaned up and put the sheets in the washer," she says as I walk in the door. "How's Kristina?"

"She told me to call her anytime I want to get laid," I answer, smiling.

"Thank you for doing that," Lauren says, stepping close and giving me a hug. "And for everything."

"Yeah, well you owe me," I say with a mock pout. "Pimping me out to all your friends. Making me eat their pussies and fuck them like I'm some kind of sex slave."

"Awww, poor baby," Lauren says, touching my cheek. "How can I ever repay you for such debauchery?" She's standing close, looking into my eyes.

"Is this my shirt?" I ask, grabbing the edges of the material and twisting them outward to expose her breasts.

"I felt weird cleaning the house naked," she shrugs. "Do you mind?"

"Mind?" I say pulling her closer to me. "This is really crossing the line, Lauren!" I tell her with mock anger. "It's one thing for us to be kissing, touching and going down on each other but wearing my clothes, that's just too much!"

"Too much what?" she asks pressing her body against me.

"Too much intimacy!" I answer. "Take it off this instant!"

"If you insist," she says with exaggerated bashfulness. "By the way, that's three things, not one," she says as she unbuttons the bottom two buttons and drops my shirt to the floor.

"What's three things?" I ask, honestly confused.

"Kissing, touching and oral sex," she smiles as she unbuttons my shirt, the one I'm wearing. "That's three things and you said it is one thing." Her hand has slid inside my open shirt and she's gliding her palm over my bare chest.

"Well, just don't cross that line again," I admonish her with dramatic flare. "You're my sister and there are certain lines we just shouldn't cross."

"Like wearing your clothes?" she asks, as she slips my shirt off my shoulders. She's completely naked and I have just my shorts on.

I tentatively put my hands on her bare back and pull her to me. Now that we're alone it feels kind of awkward to be like this with my sister. When her friends were here, we could pretend she was just going along with their antics. Now it's just the two of us.

"Are there any other lines we shouldn't cross?" Lauren asks, like she's reading my mind. She's pressed up against me but unfortunately it seems that four times might be my limit. My cock can barely register any excitement.

"Probably," I answer, lowering my mouth to hers. We kiss more tenderly this time and, if possible, it's even more erotic than when she attacked my mouth earlier. Instead of fighting for space our tongues are entwined in a tantalizingly slow dance. The kiss does nothing to dissuade me from crossing any lines.

"I'm so horny," Lauren says, breaking the kiss and focusing her beautiful eyes on mine. "I watched you fuck my friends all afternoon."

"I don't mind if you wake me up early," I say as we crawl under the covers.

"Don't go to sleep just yet, Stud," Lauren says, lying back and spreading her legs invitingly. "Is your tongue still functioning?" she teases.

"You bet!" I answer, crawling up between her legs. Her pussy is soaking wet as I tease her labia and lick around every crevice and fold.

"Oh Brandon!" she moans when I flick my tongue across her clit and slip my finger inside her soggy opening. I eat my sister to a face-drenching orgasm as she screams my name and violently climaxes against my face.

"OH GOD! FUCK! BRANDON! OH, BRANDON!" Her juices gush over my tongue as her body contorts and writhes and her hands smash my face against her splayed-open pussy. She rides out her orgasm as I lap up her steadily flowing juices.

I wipe my face on the sheet and stretch out next to my sister as she catches her breath.

"What time do you expect mom and dad?" I ask as we sit down to enjoy the pancakes. My cock has stayed perpetually hard while I've watched her move around the kitchen in her skimpy nighty.

"Not until late, around 8 o'clock tonight, I think," she smiles. "Think that gives us enough time?" she asks coyly.

"For what, Sis?" I tease between bites of pancake.

"For whatever you want," she whispers, her voice taking on a seductive tone.

"I want you," I answer honestly, her eyes reflecting the same lustful feelings I'm having.

"What are we waiting for?" she asks, clearing the table and putting the plates in the dishwasher.

As I follow her down the hall to her bedroom, I'm trying to get my mind around the fact that I'm actually going to fuck my sister! My cock has never been so fucking hard!

Lauren slips the nightie off her shoulders as she enters her room and lets it drop to the floor next to her bed. When she turns towards me I sense a hint of nervousness in her smile.

"You sure about this, Lauren?" I ask, stepping close and pulling her into my arms.

"Never been surer," she responds, kissing me lightly on the lips.

"We're really crossing a line," I remind her as I brush her hair from her face.

"Oh," she laughs, "Like showering together and oral sex wasn't?" She has a point. Lauren lies back on her bed, spreading her thighs invitingly and I crawl up between them. Her long pussy lips are already glistening with juice when I lower my face towards them.

"Just fuck me, Brandon," Lauren says, pulling on me by my shoulders. "I don't need any foreplay." I still pause at her perfect breasts to nibble on her nipples before I stretch out over my sister's welcoming body.

"I can't believe we're doing this," I tell her as I lean my body up and align my hard cock with her wide-open pussy. My cock is a steel rod, throbbing with anticipation but I pause long enough to admire my sister's beautiful body. She is a sight to behold; perfection personified. Damn!

My cock literally glides into Lauren's silky smooth pussy. She was right that she didn't need any foreplay. Her slick pussy walls welcome my incestuous intruder with a fiery intensity that heats up my shaft, which I thought was already as hot as a fireplace poker.

"Mmmmm," Lauren moans as my cock fills her snug pussy and I push against her pubic mound.

"You feel so good," I whisper, our eyes locked on each other and neither of us moving as her pussy muscles compress around my cock.

"So do you!" she responds, gripping my face in both of her hands and pulling me down for a kiss. I continue pressing my rigid cock into her as my chest comes to rest against her taut nipples and our mouths find each other. Wrapping her legs around me, she digs her heels into my ass and pushes me farther inside.

Before I can ask what's wrong, she's moved between my legs and slurped my limp cock into her mouth, swirling it around with her tongue. Fuck! That feels incredible.

"You recovered pretty fast yesterday," she says, taking a breath from my pussy-soaked cock. "I want you inside me again as quickly as you can," she smiles. "That was sooooo fucking good, Brandon!" She cups my balls as she sucks my cock back into her mouth and her tongue doesn't stop moving until my cock has fully recuperated.

"Aren't you the stud," she smiles as she scoots forward and straddles my legs. Her hand continues to corkscrew up and down my rigid shaft.

"I love you, Sis," I tell her for the second time as she positions her soggy pussy over my cockhead. The mixture of juices inside her cunt eases my entry and she impales herself on my hard cock in one swift motion.

"Of course, you do," she laughs. "Every guy loves the girl he's fucking, at the time he's fucking her. Tell me how you feel in the morning," she adds as she wiggles around to get comfortable.

Leaning forward so her beautiful breasts hang enticingly close to my face, she starts undulating her hips in some kind of a rolling motion on my cock. Fuck! With all her tricks, Kelly never even came close to make me feel like this.

Taking my hands, Lauren places them against her magnificent breasts and I rub my palms in a circular motion around her hard nipples.

"Ooh yeah," she coos. Her hair is matted to her forehead and little droplets of sweat run down between her luscious breasts. She's rolling her hips forward, sliding my cock in and out of her hot, mushy pussy while clenching and unclenching her pussy muscles around me. Fuck!

"You are amazing, Sis," I tell her, pinching her nipples and kneading her breasts. I feel a mixture of our juices running down between my ass cheeks as she continues rolling her hips in a rippling motion over my cock. I pick up on her rhythm and push my cock up deeper into her enflamed pussy, purging the remaining fluids from her cunt. .

When she leans forward again, I grab one of her nipples between my teeth and suck it hard before she pulls back and sits up straight. Giving up on the rolling motion, she starts bouncing no my cock, riding me harder and faster.

I'm thrusting my cock up, bucking wildly under her as she rhythmically jounces around on my extremely rigid pole. Squeezing her succulent breasts, I keep them from slapping against her chest as she rides me into a deeply intense orgasm.

"Oh Brandon! Oh Fuck! Brandon!" she pants, riding out wave after wave of unadulterated pleasure. "I looooove youuuuuu!" she screams, clamping her pussy muscles around my hard cock and triggering my release as she collapses on my chest. I enfold her in my arms and we lay there gasping for breath.

"Of course you do," I tease. "When you're in the throes of an orgasm. We'll see how you feel in the morning." She pounds her fist into my arm as she shoves her tongue deep into my mouth.

With my cock snuggly tucked inside her pulsating pussy and our tongues entwined in our mouths, we bask in the afterglow of our incestuous lovemaking. Neither of us wants to disengage or lose the magic of this moment but Lauren's phone rings incessantly.

"Don't even think about it," I whisper.
