I’d just backed my bass boat and trailer into my friend’s driveway after a brutal day on the lake, sweat soaking through my t-shirt and loose shorts. The neighborhood cookout was kicking off with grills firing up, couples chatting with beers in hand, and the smell of charred burgers mixing with lake water on my skin.

I hopped into the boat to pack away my rods and tackle, swinging my legs over the side so I sat facing the yard, feet dangling a couple of feet off the ground. My boxers were baggy and damp. The shorts were riding up due to the heat. No one around gave a shit in this laid-back crowd.

That’s when she wandered over, my neighbor’s daughter Mandy, the slim 18-year-old geek with glasses and an awkward vibe, as if she spent more time with books than boys. She stopped right in front of me, maybe three feet away, her eyes level with my crotch thanks to the boat’s height. Through my mirrored shades, I saw her glance drop.

Fuck, a rip in the left leg of my shorts from snagging on the trailer hitch earlier. With these loose boxers, my heavy balls were hanging right out, the thick base of my cock peeking too. My heart pounded. It was accidental, but the thrill hit hard, my dick twitching at the exposure.

“Hey, Mandy, mind grabbing me a cold water from the house?” I said, keeping my voice casual. “I’ll be another fifteen minutes sorting this gear.”

She nodded quick, cheeks pink, and scurried off without a word. Alone now, my cock stirred in my shorts, blood rushing south from the rush. I reached down, fluffed my balls and shaft through the fabric, then tugged the boxers aside so my whole package, thick cock, soft but heavy, full balls sagging low, dangled free through the gap. I widened the tear a bit with my fingers, setting up the perfect ‘oops’ for when Mandy came back.

She returned fast, water bottle in hand, stepping right up to the boat’s edge. I leaned forward to grab it, spreading my thighs wide for balance, and there it was, my fat cock and balls swinging out inches from her face. Thick shaft hanging heavy, veins faint but pulsing, balls tight against the heat. I swigged the water like nothing was up, legs splayed, pretending to check my phone.

Mandy didn’t back off. Instead, she crossed her arms, leaned down to rest them on the gunwale, chin on her forearms. Now her glasses-framed eyes were dead level with my crotch, locked on my exposed meat. No blush, no looking away, just pure, mesmerized staring at my mature cock, soft but starting to thicken under her gaze. I could hear her breath hitch, shallow and quick, as Mandy took in every inch.

The way my balls hung low and full, the girth of my shaft dangling like it owned the space between us. My pulse throbbed in my dick, making it swell, veins bulging as it lengthened toward half-hard. Mandy shifted her weight, thighs squeezing together under her shorts, but she stayed glued, silent, like a virgin getting her first up-close lesson in real man cock.

I kept sorting tackle behind me, twisting just enough to keep my legs wide, the boat rocking slightly with my movements. My cock kept growing, blood pumping hard now, tip flaring as pre-cum beaded at the slit. It swung with the boat’s sway, heavy and insistent, inches from the teen’s parted lips.

Mandy’s eyes followed every twitch, pupils wide behind those glasses, and I swear I saw Mandy’s tongue dart out to wet her mouth. Fuck, this shy little thing was hooked, her inexperience turning to raw curiosity, thighs rubbing subtle as her pussy probably soaked through her panties.

Then her mom, Julia, called from the house. “Hey, we need to grab some ice. Can you help?”

That curvy 40-something with the sociable laugh, hips swaying in tight jeans, as she strolled over. Mandy blinked, snapping out of it, but Julia planted herself right beside her, both of them at my crotch level now. I closed my legs a fraction for cover, nodding hello.

“What’s up, ladies? Good to see you,” I said cheerily.

Julia smiled, chatting about the neighborhood cookout, but as I reached right for a tackle box, I spread wide again.

Boom, full exposure.

My cock was throbbing now, nearly full mast, thick shaft jutting out of the gap, balls pulled up tight from the arousal. Mom’s eyes dropped like magnets, widening at the sight of my big, veiny dick on display, pre-cum dripping slow from the head.

Mandy’s gaze snapped right back, both women fixating openly, thinking it was all a clueless accident. Julia’s sociable mask cracked. Her lips parting, breath coming faster, her curvy tits rising under her tank top as nipples poked through. Mandy mirrored her, chest heaving, silent but bold now, staring at my twitching cock like she wanted to touch.

I held the pose, legs splayed, pretending to rummage in the box while my dick pulsed under their stares. The thrill shot through me, cock jerking visibly, more pre-cum oozing down the shaft. Public as fuck with the cookout buzzing nearby, but they devoured me with their eyes. Julia’s tongue tracing her lower lip, her daughter’s glasses fogging slight from her breath.

No words about it, just that forbidden tension coiling, their breathing syncing with mine, heavy and urgent. My balls ached, ready to burst, wondering if one of them would crack first and reach out...

I couldn’t hold back anymore. The way their eyes burned into my exposed cock pushed me over the edge. Through my mirrored shades, I locked eyes with Mandy first, those wide, geeky eyes behind her glasses, pupils blown out from the sight of my throbbing meat. Her cheeks flushed deep red, like she’d been caught with her hand in the cookie jar, but she didn’t look away. Instead, she took a shy step closer, her slim body pressing right up against the boat’s edge, fingers trembling at her sides.

Julia stayed planted beside her teen daughter, curvy hips cocked, her breath hitching as she watched the exchange, nipples hard points under her tank top, but she didn’t interrupt, just devoured the scene with that intrigued gleam in her eye.

Fuck, the public thrill hit harder with both of them so close, the cookout laughter echoing faint in the background like it was a million miles away. My thick cock twitched hard in the open air, pre-cum slicking the veiny shaft, balls heavy and aching below. I wrapped my hand around the base slow, fingers gripping the girth as I gave it a long, deliberate stroke from root to tip.

The skin slid easy over the swelling head, making it jerk in my fist, a fat bead of pre-cum oozing out and dripping down onto the boat deck. Her gaze followed every pump, intense and unblinking, her thighs squeezing tight under those shorts like her pussy was clenching in rhythm.

“See something you like, Mandy?” I growled low, voice rough from the heat building in my gut.

She bit her lip, silent but bold now, her flush spreading down her neck. I stroked again, slower this time, letting the full length of my fat dick fill my hand, thick as her wrist, veins pulsing hot under my palm. It throbbed visibly, the head flaring purple, begging for more eyes on it.

Julia shifted beside her, crossing her arms under her tits to push them up, her own breath coming in short pants, but she kept quiet, letting her daughter have the front row.

Mandy’s fingers twitched harder, like she was fighting the urge to reach out, her awkward frame trembling with that forbidden curiosity. I leaned forward a bit, the boat rocking gentle, and hooked my free hand out toward her face. My fingers caught the edge of her glasses, pulling them down slow onto her nose so they perched low, exposing her flushed cheeks and those vulnerable, wide eyes fully.

No hiding now, her face was all pink skin and parted lips, innocent but starving for this mature cock lesson. She gasped soft, a tiny sound that shot straight to my balls, making them tighten up.

“Come on, touch it,” I said, grinning confident, my hand still lazily pumping my shaft right in front of her. “It’s just hanging out. It feels even better up close. Bet you’ve never wrapped your fingers around a real man’s dick before, huh? Go ahead, feel how thick it is.”

Teasing her like that, watching her innocence crack under the weight of her own heat, had my cock leaking more, the slick sound of my strokes filling the air between us. Her mom’s eyes flicked between us, lips wet as she licked them, her curvy body leaning in subtle, like she was next in line but holding back to savor the show.

She hesitated, trembling fingers hovering inches from my twitching cock, her breath hot and ragged against my skin. The air smelled like sweat and lake water mixed with that musky scent of arousal, hers, mine, even mom’s as she watched. Her hand shook as she finally reached out, fingertips brushing the underside of my shaft, tentative, right along the bulging vein.

Fuck, her touch was electric, soft and unsure, sending a jolt up my spine. My dick jerked hard in response, slapping light against her palm, pre-cum smearing sticky on her skin. She froze for a second, eyes locked on the way it pulsed, then her fingers curled hesitant around the girth, barely able to close fully around my thickness.

“That’s it,” I murmured, voice thick, stroking over her hand now to guide her, making her feel the heat radiating off my meat. “Squeeze a little ... Yeah, like that. Feel how hard you’re making me? All from staring at my balls swinging free.”

Her cheeks burned hotter, but she didn’t pull away. Instead, her grip tightened just a fraction, thumb brushing the slick head accidental, spreading my pre-cum around. A soft whimper escaped her, thighs rubbing desperate under her shorts, her pussy probably dripping wet from the forbidden touch.

Julia’s breathing quickened beside her, hand drifting casual to her hip, eyes glued to the way Mandy’s fingers explored my cock, stroking slow now, guided by my hand, the public exposure ramping up the urgency.

The tension coiled tighter, my balls churning heavy as her innocent strokes picked up speed, her shyness melting into bold curiosity. I spread my legs wider, letting my heavy sack dangle full against the boat edge, inviting more.

Julia leaned in closer, her curvy tits brushing the gunwale, whispering something low to her daughter that I couldn’t catch, but it made the girl’s hand falter, then grip firmer. Fuck, with the cookout crowd just yards away, oblivious, this casual encounter was heating to a boil. My cock throbbing urgent in her trembling fist, wondering how far she’d go before one of them begged for more.

Mandy’s fingers wrapped tighter around my thick cock, stroking up and down with that shaky eagerness, her thumb smearing my pre-cum over the swollen head. The slick sounds mixed with the distant grill sizzle, the public air thick with our hidden heat.

Julia’s eyes burned into the scene, her curvy body shifting closer, tits heaving under that thin tank. I could smell her arousal now, sharp and wet, mingling with the lake’s musty scent and my own sweaty balls dangling heavy below.

With a wicked grin splitting my face, I reached out again, sliding her glasses back up the bridge of her nose to hide those flushed cheeks just a bit. But it didn’t matter. Her vulnerability was all over her, that geeky innocence cracking wide open. I leaned in close, my breath hot against her ear, lips brushing the shell as I whispered filthy commands low and rough.

“Get on your knees, Mandy. Wrap those shy lips around my fat cock and suck it deep. Show me how bad you want to taste this thick meat while your mom’s watching every second.”

She shivered hard, a soft whimper bubbling out, but her hand didn’t stop pumping my shaft, veins throbbing under her grip, the head flaring slick and purple. Her eyes flicked up to mine through those lenses, wide and locked, then down to my twitching dick.

Without a word, Mandy dropped obedient, knees hitting the grass beside the boat with a thud, her slim frame folding up to bring her face level with my exposed crotch. The boat dipped slight from the shift in weight, but I spread my legs wider, thighs flexing to push my heavy balls forward, cock jutting out inches from her parted lips.

Fuck, the sight of her down there, awkward glasses and all, staring at my girth like it was her first dirty secret, public, forbidden, right by the driveway with neighbors chatting oblivious yards away, had my pulse hammering. She hesitated one beat, tongue darting out to wet her lips, then lunged forward, eager.

Mandy’s mouth stretched wide around the head, hot and wet, sucking hard as she took me deep in one go. Lips sealed tight around my thickness, tongue swirling sloppy under the shaft, she bobbed quick, cheeks hollowing with the pull. Saliva dripped down her chin already, mixing with my pre-cum, the slurping sounds wet and urgent in the open air.

“That’s it, suck that dick like a good girl,” I groaned low, hand tangling in her hair to guide her deeper, forcing another inch past her teeth.

Mandy gagged soft but didn’t pull back, eager now, throat working to swallow more of my fat cock, her glasses fogging up from the heat. Her free hand gripped my thigh for balance, nails digging in as she hollowed her cheeks harder, sucking with raw hunger. My balls slapped light against her chin with each thrust forward, heavy and full, swinging free in the breeze.

Beside her, Mom Julia finally cracked. Her sociable facade shattering as she yanked her tank top over her head, those curvy tits bouncing free, nipples stiff and dark in the sun. She kicked off her shorts next, no panties underneath, her thick thighs spreading as she leaned against the boat’s edge.

Fingers dove straight between her legs, sliding into that shaved pussy with a wet squelch, two digits pumping in and out slow at first. Julia moaned soft, breathy, eyes glued to her daughter’s bobbing head on my cock, her own hips bucking subtle to fuck her hand deeper.

“God, look at you taking that big dick,” Julia murmured, voice husky, arousal dripping down her inner thighs.

The boat rocked gentle with our rhythm. My hips thrusting shallow into the girl’s mouth, her sucks pulling loud and sloppy, mom’s fingers plunging faster now, her moans syncing up. Afternoon sun beat down hot, catching the slick sheen of sweat on our skin: beads rolling down my chest, glistening on the girl’s neck as she slurped, tracing mom’s curvy sides where her hand worked her clit in circles.

The air hummed with it, wet smacks of mouth on cock, fingers in pussy, our heavy breaths mixing with the faint cookout chatter. My cock twitching deep in the teen’s throat, the thrill of eyes on us, even if just these two, making my balls tighten urgent.

Mandy sucked faster, eyes locking up at me through fogged glasses, tears streaking her cheeks from the depths, but she didn’t stop, tongue lashing the underside, throat convulsing around my girth. Julia’s hips moved rhythmic, ass grinding against the boat hull as her fingers curled inside, hitting that spot that made her gasp louder, tits jiggling with each pump.
