Private Lessons by the Lake

The moment I stepped into the lake house, the air crackled with something electric. Sarah stood there in her tight black waitress skirt that barely covered the swell of her ass, the same uniform she wore at the diner where she served me coffee every morning. Her cheeks flushed when our eyes met, and I could see the way her nipples pushed against the thin white blouse she hadn't changed out of yet.

"Mark... you really came," she whispered, biting her lower lip. The rental was quiet except for the soft lap of water against the dock outside. Sunlight poured through the big windows, catching on the buttons of her blouse like an invitation.

I closed the door behind me, my cock already thickening in my jeans. "Couldn't stop thinking about what you said last week. That you wanted me to teach you... properly."

Sarah's breath hitched. She was twenty-four, all curves and nervous energy, and I'd been her favorite regular for months. Last Tuesday she'd slipped me her number with a note: "I need an instructor. Someone who won't be gentle." Now here we were.

She didn't wait for more talk. Her fingers flew to the top button of her blouse, popping it open with shaky urgency. "Show me then. Teach me how you like it." Another button, then two more, revealing a lacy white bra that barely contained her full tits. The fabric strained as she shrugged the blouse off her shoulders, letting it drop to the wooden floor.

My hands were on her in seconds, yanking the zipper of her skirt down. The material slid over her hips with a whisper, pooling at her ankles. She kicked it away, standing there in just her bra, tiny black panties, and those sensible waitress flats. I spun her around, pressing her against the cool glass of the picture window overlooking the lake.

"First lesson," I growled against her ear, unhooking her bra with one hand while the other shoved her panties down her thighs. "When I tell you to bend, you bend." Her tits spilled free, nipples hard and pink. I cupped one roughly, rolling the peak between my fingers until she moaned.

"Yes, instructor," she gasped, arching back into me. Her ass, round and firm from hours on her feet, pushed against the bulge in my pants. I freed my cock, thick and heavy, letting it slap against her bare skin. She shivered.

I kicked her feet wider apart, the flats scraping on the floor. No slow buildup. I lined up and thrust into her pussy in one long stroke. She was soaked, her walls gripping me like wet velvet. "Fuck... you're tight," I muttered, gripping her hips hard enough to leave marks.

Sarah cried out, palms flat on the window. "Harder. Teach me how to take it." I pulled back and slammed in again, setting a brutal rhythm that made her tits bounce against the glass. Each thrust pushed her up on her toes, her breath fogging the pane. The lake sparkled beyond us, indifferent to the way her pussy clenched around my dick.

I reached around and found her clit, rubbing tight circles while I fucked her deeper. "Lesson two: don't hold back those sounds." She didn't. Moans spilled from her lips, raw and needy. "Mark... oh god, your cock feels so good stretching me."

We moved then, my arms wrapping around her as I walked us to the big leather couch without pulling out. I sat down, pulling her onto my lap facing away from me. Her skirt was long forgotten; only the waitress flats remained on her feet as she sank back down onto my shaft. The new angle made her whimper, her juicy ass rippling every time she dropped onto me.

"Ride it like you mean it," I ordered, spanking her left cheek sharply. The sound cracked through the room. She obeyed instantly, bouncing faster, her pussy making wet, obscene noises around my cock. I watched where we joined, mesmerized by how her lips stretched around my thickness, cream coating my balls.

"Like this, instructor?" she panted, grinding in circles that made her clit drag against my base. Her back arched, tits thrust forward. I reached up and pinched both nipples, tugging them until she squealed.

"Exactly like that." The pace turned savage. I thrust up to meet her, our bodies slapping together. Sweat slicked her skin, making her glide easier. She came first, her pussy spasming wildly, juices dripping down my thighs. "I'm... I'm coming so hard!"

I didn't stop. Flipping her onto her back on the couch, I hooked her legs over my shoulders, the flats dangling comically. I drove back in, pounding her through the aftershocks. Her eyes rolled back, mouth open in a silent scream. The second orgasm hit her even harder, her walls milking me until I couldn't hold back.

With a deep groan I buried myself to the hilt and came, flooding her pussy with thick ropes of cum. It overflowed, leaking out around my cock as I gave a few final lazy thrusts.

Afterwards the room was quiet except for our breathing. I pulled out gently and collapsed beside her, drawing her against my chest. Her body was limp, satisfied, the faint scent of her arousal and my cum mixing with the fresh lake air drifting through the cracked window.

Sarah traced a finger over my collarbone, her voice soft and sleepy. "Did I pass the first lesson?"

I chuckled, kissing her damp forehead. "With flying colors. But there are plenty more where that came from."

She smiled, snuggling closer, her waitress flats still on as our heartbeats slowed together. "Good. Because this regular customer plans on booking every private session you offer."
