The Gamblar

The bet get our old neighbor on her back and fuck her!

The evening sun hung low over the cabin village, casting long shadows across the wooden porches and the dusty trail we'd just hiked. My heart pounded from the run, but mostly from the rush of what I'd just pulled off with Ida. She'd been bent over that rickety picnic table behind her cabin, her skirt hiked up around her waist, moaning low as I thrust into her from behind. Her silver-streaked hair fell loose, and she gripped the edge of the wood, her body still firm from all those mountain runs. I didn't hold back pounded her hard until she shuddered and clenched around me, her pussy soaking my cock. My sister had watched from the bushes, her eyes wide, but she hadn't run.

Now, as I leaned against the wall of the empty cabin, zipping up my shorts, my sister appeared around the corner. Her face was red, not just from the heat flushed with something hotter. Sweat glistened on her neck, trailing down into the V of her tank top, where her tits rose and fell with quick breaths. 'You planned this, didn't you?' she hissed, glancing over her shoulder like someone might catch us. Her voice was shaky, but there was a glint in her eyes, that mix of shock and curiosity we'd always shared growing up.

I grinned, stepping closer. 'Maybe. But you said you'd play along. And now?' I reached out, brushing a strand of hair from her face. She didn't pull away.

She bit her lip, crossing her arms under her chest, pushing her breasts up. 'I can do your ass. That's the deal, right? For watching you rail that old lady like some animal.' Her words tumbled out, half-laughing, half-breathless.

'Hell no, you don't,' I shot back, my voice low. 'That ass is off-limits. Never happening.' I grabbed her wrist, pulling her into the shadowed side of the cabin, away from the trail. 'Fuck my cunt. Use a condom and pull out.'

'I don't have a condom,' I admitted, my hand sliding to her hip, feeling the curve through her shorts.

She hesitated, then nodded, her cheeks burning. 'Alright, but you're pulling out. This is so embarrassing... I'm not gonna face you while you do it.' She turned away, bracing her hands against the cabin wall, arching her back just enough to press her ass toward me. Her shorts hugged her thighs, and I could see the outline of her panties underneath.

My cock twitched, already half-hard from Ida. I stepped up behind her, hands on her waist, tugging her shorts down in one swift pull. They pooled at her ankles, exposing her round cheeks and the thin strip of fabric between her legs. She was damp already her arousal soaking through the cotton. I hooked my fingers in her panties, yanking them aside, and there it was: her pussy, pink and swollen, lips parted like she was begging for it.

'Bro...' she whispered, but it wasn't a stop. It was a plea.

I freed my dick from my shorts, stroking it once to full hardness. Thick veins pulsed along the shaft, the head slick with leftover from Ida. I pressed against her entrance, rubbing the tip up and down her slit, coating myself in her wetness. She gasped, pushing back a little, her body betraying her words.

'Just do it,' she muttered, head down, hair curtaining her face.

I gripped her hips and thrust in, slow at first to feel every inch stretch her. She was tight tighter than I imagined, her walls gripping me like a vice. A low groan escaped her as I bottomed out, my balls pressing against her clit. 'Fuck, sis,' I breathed, starting to move. In and out, steady pumps that made her body rock forward.

She stayed quiet at first, just soft whimpers with each slap of skin on skin. I reached around, fingers finding her clit, rubbing circles while I fucked her deeper. Her pussy clenched, juices dripping down her thighs. 'Harder,' she finally said, voice muffled against her arm.

I obliged, slamming into her now, the cabin wall creaking under her grip. Her ass jiggled with every thrust, and I watched my cock disappear into her over and over, glistening with her cream. The taboo of it all the fact that she was my sister, married with kids, same as me made it filthy, electric. I leaned over her, breath hot on her neck. 'You like watching me fuck Ida? Made you wet, huh?'

'Shut up,' she panted, but she ground back against me, chasing the friction.

I sped up, hips pistoning, the wet sounds echoing in the quiet village. Her breaths came faster, ragged, and I felt her tighten, on the edge. 'Gonna cum,' she warned, voice breaking.

'Not yet,' I growled, pulling almost all the way out before plunging back in. But she was gone her pussy spasmed around me, milking my cock as she came hard, thighs quivering, a choked moan slipping out.

That pushed me over. I thrust deep one last time, then yanked out, stroking fast. Hot ropes of cum shot across her ass cheeks, splattering her skin, dripping down toward her pussy. I groaned, watching it mark her, the evidence of what we'd done.

She sagged against the wall, catching her breath, not turning around. 'Get me something to clean up,' she said finally, voice hoarse.

I tucked myself away, grabbing a napkin from my pocket and wiping her off gently. She pulled up her shorts without a word, still facing away. But as she straightened, she glanced back, a small, wicked smile. 'Don't think this changes anything. We're still just running the trails.'

I chuckled, pulling her into a quick hug from behind. 'Sure, sis. Whatever you say.' But we both knew the trails just got a whole lot more interesting.
