Pearl underwear made her cum at the park...

A few years back on our anniversary I surprised my girlfriend with the pearl underwear I'd bought online. It was this stunning black thong with delicate string of smooth, lustrous pearls. She slipped it on in our bedroom, her eyes lighting up with that mischievous spark as she adjusted the pearls so they pressed gently along her pussy, the largest one sitting right over her clit. 'You're evil,' she laughed, but the way her cheeks flushed told me she was already intrigued. We decided to test it out on a walk through the park nearby nothing too crowded, just a leisurely stroll to see how far we could push each other.

We stepped out hand in hand, the warm breeze brushing against our skin as we hit the path lined with tall trees. She wore a light sundress that swayed with her hips. I could tell from the start that the pearls were doing their job; her steps were a bit shorter, more deliberate, like she was trying to control the friction. 'Something bothering you?' I whispered, leaning close as we walked side by side. She bit her lip and shot me a sideways glance.

I grinned and squeezed her hand, pulling her a little closer so our arms brushed. To tease her more, I suggested we pick up the pace, saying the fresh air would do us good. She hesitated but followed, her thighs pressing together with each stride. I watched her closely the way her breath hitched when the pearls shifted, grinding softly against her swelling clit. 'Keep walking like that,' I murmured. She nodded, her free hand clenching at her side as a soft whimper escaped. The path curved gently, and I made sure to guide her over a few uneven spots, each bump making her jolt slightly.

But she wasn't one to just take it; oh no, she knew how to fight back. As we passed a quiet stretch of the trail, she let her hand trail down my arm, her fingers glazing lightly over my shirt before slipping to my waistband. 'You think you're the only one who can play dirty?' she purred. She pressed her body against mine for a moment, her breast grazing my side as she whispered, 'I can feel how hard you're getting just from watching me squirm.' Her hand dipped lower, brushing the front of my jeans where my cock was already straining against the fabric. She gave it a gentle squeeze through the denim.

We kept going, the teasing building like a slow burn. Further along, the path narrowed, forcing us to walk single file for a bit. I took the lead, but every few steps, I'd glance back keeing her on edge. 'Imagine if someone saw how those pearls working your clit, making your pussy drip.

The arousal hung thick between us. Sweat beaded on her forehead, and I could see her nipples poking through her dress, hard and begging for attention. She was soaking the pearls, I knew it the way her thighs rubbed together, trying to chase more friction without giving in too soon. I teased mercilessly, describing in hushed tones how her clit must be swollen, the pearls gliding over it slick with her juices, each pearl bumping her sensitive nub relentlessly. 'You're close already, aren't you? She moaned quietly, her hand finding mine again, but this time she guided it to her hip, pressing it there so I could feel the subtle tremors in her body.

Her retaliation came in waves too. As we rounded a bend with fewer people in sight, she leaned in and nipped at my earlobe, her breath hot. 'Keep talking like that, and I'll make you cum in your pants before we even sit down.' Her fingers danced over my zipper, tracing the length of my cock, feeling it pulse under her touch. She pressed harder on the head, smearing the pre-cum around until my underwear was drenched, my balls aching from the denial. 'Look at you, cock leaking like a faucet. Bet you'd love to shove it in me right here, but not yet.' The mix of her words and the subtle gropes had me gritting my teeth, my shaft twitching with every pass of her hand.

Finally, after what felt like an eternity of this delicious torment, we reached the far end of the park a secluded bench tucked under trees, completely isolated. No one around, just the rustle of leaves and our heavy breathing. We collapsed onto the wooden seat, her body slumping against mine as the walk's buildup crashed over her. 'I can't... it's too much,' she panted, her legs parting slightly under the dress. The pearls had been merciless, rubbing her clit raw with every step, her pussy lips puffy and drenched. I pulled her closer, my hand sliding up her thigh to where the pearls met her heat. I urged, my fingers brushing the string, feeling the slickness coating them.

She arched against me, her hand instinctively grabbing my cock through my jeans again, squeezing hard as her own release built. The final teases from the walk those endless rubs against her throbbing clit pushed her over. Her body tensed, thighs clamping together as the pearls ground one last time. 'Fuck... I'm cumming,' she gasped quietly, her pussy convulsing around the invading string, juices flooding out to soak her thighs and the bench beneath. She shuddered violently, moans spilling from her lips as waves of pleasure ripped through her, her clit pulsing against the pearls. I held her tight, my own cock leaking profusely now from her grip, pre-cum staining everything.

When she finally came down, panting and flushed, she turned to me with a wicked smile, her hand still on my bulge. 'Your turn next time,' she whispered, but for now, we just sat there, basking in the afterglow of our outdoor tease.
