My girlfriend’s older sister is less domesticated than she appears [MF]

“What are their names again?”

Jennifer grins behind her oversized sunglasses, looking relaxed as she drives us out of the city, steering the car down the winding forest highway. She’s got on a wicker hat and breezy sundress and, I can’t see it at the moment but I know it’s there, a sexy lace thong that shows off her fantastic ass. “My sister’s Alexa,” she starts.

“Yeah.”

“Her husband is Robert.”

“Ok.”

“But he’s not coming this weekend, he’s on a work trip. And her boys are Abe, twelve, Jacob, ten, Reuben, seven, and Asher, five.”

I rub my face with my hand. “I’m not expected to remember all that, am I?”

“Relax,” she says, squeezing my knee, “You’ll do fine. My sister’s chill, like me. You’ll love her.”

“We’re not sharing a room with any of them, are we?”

Jennifer laughs. “No.” Then she adds, “We are sharing a bathroom with the kids, though.”

“What?!”

“Don’t be a baby about it.”

But I am. I am a baby about it. I like my showers long and uninterrupted.

A couple hours later, we pull up at a two-story log cabin sitting in a clearing. There’s views of a valley below, and a creek to one side. Maybe this won’t be half bad.

Jennifer rushes inside to use the restroom, and I’m left to unload our gear by myself.

Laden with bags, I turn around, and there’s a woman standing there, looking a lot like a slightly older version of Jennifer, but with hair cut short and practical. She’s got on simple white shorts and a pink top.

“Alexa?” I guess.

“I am,” she grins, tucking her chin, eyes sparkling. She looks me up and down, tongue just visible between her teeth, like she’s checking me out. “I’d offer to help with your stuff,” she says, “But you don’t look like you need it.” She winks.

“Uh…” I’m baffled by her, unsure what to say. “I’m Cole.”

“I know,” she says, the grin fixed on her, “Let me show you which room is yours. Follow me.”

She leads me through the cabin. “I’m in the master, down here,” she points. I nod, then she takes me up the stairs to a small bedroom. It’s rustic, but Jennifer and I don’t need much. “Cool,” I say.

Alexa watches me set the bags down, the knowing glint lingering in her eye. “If you need anything,” her gaze flicks to my crotch and back, “You just let me know, ok?”

“I… uh, yeah.”

Then Jennifer walks in, and her sister’s flirtation evaporates. The siblings chat and catch up, and I go wander downstairs, looking for something to drink.

The afternoon turns into evening, and I’m actually having a good time. Turns out, I get along good with the kids, and I end up staying up with them at the campfire, playing games. Alexa’s weird impishness doesn’t return, and I forget about it.

I jolt awake in the morning light, see Jennifer slipping into her swimsuit. “What time is it?” She had been asleep by the time I’d gotten to bed.

“A little past seven,” she says, “But you can sleep more if you want. I’m taking the kids to that swimming hole a few minutes from here. They never sleep in.”

“Yeah,” I yawn, and then I’m back asleep.

I wake again, and the sun has climbed up the sky. The house is quiet, and I remember about the bathroom. This is my chance to bathe at my own pace.

At least, I thought. I make it halfway through my shower — shampooing my hair — when I hear a hand on the bathroom door. “Someone’s in here,” I shout.

My eyes are pinched shut, but the door squeaks as it opens, and I call out, “Hey! Privacy! I’m almost done.”

The shower curtain rustles. “Jennifer?” I venture.

“I just want a harmless peek,” a woman’s voice says, sounding almost like Jennifer, but not quite.

“Alexa?” I say.

“Jennifer sure knows how to pick ‘em.”

I scramble, brushing the shampoo from my eyes, “What’re you doing?”

“I told you,” she says, “Ogling.”

I open my eyes despite the stinging, see Alexa grinning at me. She’s in a plush bathrobe. I spin around, putting my back to her. “I don’t– I don’t think–”

“What?” she says, “You don’t think Jennifer would like me doing this?”

“No!”

“Are you going to tell her?” she coos, her voice growing closer to me, “Are you going to tell her you showed me your fat cock? That you saw my tits?”

“What?!” I glance over my shoulder, an automatic thing, and Alexa’s let her bathrobe fall open around her chest. I whimper.

Her grin spreads. “Not bad for a mom, right?”

Her tits are big and round and in eager need for a groping. “I shouldn’t–”

“You shouldn’t what?” She purrs, growing closer still, stepping over the high threshold, joining me in the shower-tub.

“This… this…” I stammer, keeping my back towards her, some ridiculous attempt at modesty.

“You seem nervous,” she says, her lips brushing my ear, her chin on my shoulder. I feel her warmth press into my back, those big tits rubbing against me. “Let me relax you,” she says, wrapping her arms around my hips.

The steam of the shower billows around me, and I’m tense, frozen in place, unable to make a decision. But even doing nothing is tacit approval, and her hands slide over my slicked skin, fingertips brushing along my waistline.

She makes a delighted hum as her hands curl around my limp cock. “What have we here?” She pulls on my shaft, quick, precise yanks, while she uses her other hand to cup my balls.

She’s a fucking expert, or I’m super turned on, or maybe both, because I spring erect pretty much instantly. “What’re you doing?” I pant.

She chuckles, stroking my cock, playing with my balls, “I thought that was obvious.”

Between gasps, I say, “But why?” She’s skillful and practiced, her fingers rubbing me in just the right places and in just the right amount. She fills me with bliss but keeps me on the edge, desperate for just a bit more.

“What, you don’t like it?” she teases. She pinches the head of my cock in one hand, holding it up. She then run a fingertip slowly, gently up and down the vein on the bottom of my dick. “Why do I have to have a reason? I saw something I wanted, and I’m taking it.” She grabs my shaft in a fist, with a powerful grip I never would have expected, and tugs on my balls while jerking. “And now you’re going to cum for me like a good boy.”

Despite what’s going on with my penis, my brain just won’t let this go. “But you’re married!”

“He shouldn’t have left me alone,” she says, “He knows I’m a horny bitch. Four kids doesn’t just happen. Now shut the fuck up or I’ll leave you with blue balls.” Her index finger massages my glans, and my cock is fat and swollen and in heaven.

“Squeeze my balls,” I groan, “Harder.”

She giggles and grips them, fingers wrapping around them in a mighty tug, far more forceful than her sister ever does. I grunt, my eyes pinching closed, my head rolling back. And then I’m cumming, Alexa draining the spunk from me with a practiced art.

“There’s a good boy,” she coos, my cum spraying out, oozing from my cock in a thick river, down my shaft and over her hands, mixing with the hot shower water at my feet. She wrings my dick with a tight pinch, and I keep cumming. “Fuck, you cum a lot. My sister not drain your balls enough? Don’t answer that, it’s rhetorical.”

She pulls back, and I turn around, look at her. She’s grinning, proud and pleased. “How’d I do?”

“That was…” I say, “Well, amazing.”

“Thanks,” her grin spreads, “Good to know I still got it.” She washes her hands in the sink. “Now, this was fun, but I’ve got to go make lunches for the kids. I’ll catch you later.” She winks and pulls her robe back over her tits.

That night, I make sure Jennifer and I get to bed early, and I go down on her and fuck her how she likes best and make sure she climaxes good and long and she’s a little taken aback by all this, I can tell, not that she’s complaining. But afterwards, when I fuck her to make myself cum, what finally gets me off is thinking about her sister.

I’m so fucked.
