Bikini Under the Suit

The moment I saw her across the crowded office party, my cock twitched hard. Lisa, my married neighbor from down the street, stood there in a tight little black dress that barely contained her curves, but the real surprise came when she whispered that she was wearing the tiny red bikini underneath—the same one I'd jerked off thinking about all summer while she sunbathed in her backyard. Tension crackled between us instantly, her eyes locking on mine with that knowing, hungry look. The party was at our firm's rooftop bar downtown, the city lights glittering below, and the open bar had everyone loose and laughing. Two sentences in and I already wanted to drag her somewhere private.

"Mark... you came," she said, sliding up to me with a glass of champagne in her manicured hand. Her voice was low, teasing, like we were the only two people in the noisy room.

"Yeah, couldn't miss it. You look fucking incredible, Lisa. That dress is killing me."

She bit her lip, leaning in so her perfume—something sweet and spicy—hit me. "You have no idea what's under it. Remember that red bikini I wore last weekend? The one that barely covers my ass? It's all I have on tonight. No bra. No panties. Just strings and wet pussy."

My dick jumped in my slacks. The image of those tiny triangles stretched over her big tits and shaved slit made my mouth go dry. We'd flirted for months over the fence, but tonight the alcohol and the crowd gave us cover. I glanced around—no sign of her husband, who was stuck at another work thing.

"Jesus, Lisa. You're soaked already?"

She nodded, cheeks flushing. "Since I saw you walk in. My clit’s been throbbing thinking about your big cock. Want to feel?"

Before I could answer, she grabbed my hand under the high table and pressed it between her thighs, right there in the middle of the party. The dress rode up easily. My fingers brushed the smooth fabric of the bikini bottom—already damp, the thin material clinging to her swollen lips. She gasped softly.

"Fuck, you're dripping," I whispered, circling her clit through the bikini with my thumb. The string dug into her juicy ass as she rocked against me.

"Mark... keep going. Nobody's watching. Rub my pussy harder."

Her breath hitched when I slipped a finger under the bikini crotch, finding her bare, slick folds. She was shaved smooth, hot and slippery. I pushed two fingers inside her tight cunt right there, pumping slowly while people chatted ten feet away. Lisa's eyes fluttered, her tits heaving under the dress.

"Oh shit... your fingers feel so good stretching me. Deeper. I need your cock soon or I'm gonna cum on your hand."

We lasted maybe five minutes before the tension snapped. "Bathroom. Now," I growled. She nodded, biting back a moan as I pulled my fingers free, glistening with her juices. We slipped through the crowd, her ass swaying in that dress, the bikini strings probably riding up between her cheeks.

The single-stall executive bathroom on the lower floor was empty. I locked the door and spun her around, yanking the dress up to her waist. The red bikini was even smaller than I remembered—two tiny triangles over her heavy breasts, the bottoms just a scrap that disappeared between her thick ass cheeks.

"God, look at you," I said, palming her tits and pinching her hard nipples through the wet fabric. "This bikini is fucking obscene."

"Take it off me," she begged, reaching back to stroke my bulge. "I want you to fuck me in it first, then rip it aside."

I bent her over the marble sink, her hands gripping the edge, tits spilling out as the top shifted. She spread her legs, the red strings framing her perfect ass. I unzipped, my thick cock springing free, already leaking pre-cum. I rubbed the head along her bikini-covered slit, soaking the fabric more.

"Stop teasing, Mark. Shove that big dick in my married pussy. Fuck me like you own it."

I hooked the bikini bottom to the side, exposing her glistening pink hole, and thrust in hard. She cried out, the sound echoing off the tiles.

"Fuuuck, you're huge. Stretch me... yes, just like that."

I pounded her from behind, the wet slap of my hips against her ass filling the room. Her bikini strings bounced with every thrust, rubbing her clit as my balls smacked her. I reached around, fingering her swollen nub while I railed her deep.

"You're so fucking tight, Lisa. This cheating cunt is gripping me like a vice."

"Harder! Pull my hair. I'm such a slut for your cock."

I grabbed a fistful of her dark hair and yanked her head back, driving faster. Her pussy clenched, juices running down her thighs onto the bikini. She came first—hard—shaking and squirting a little around my shaft, moaning loud enough I had to cover her mouth.

"Don't stop... I'm cumming again. Fill me up, Mark. Cum in my pussy."

I flipped her around, lifting her onto the counter. Her legs wrapped around me, red bikini top now pushed up so her big tits bounced free. I sucked a nipple into my mouth while I slammed back inside her, the new angle hitting her G-spot perfectly. She clawed my back, whispering dirty shit between gasps.

"Yes... right there. Breed my married hole. My husband never fucks me like this."

The pressure built fast. I felt her second orgasm rip through her, pussy pulsing and milking me. I couldn't hold back—my cock swelled and I exploded, pumping thick ropes of hot cum deep into her spasming cunt. It overflowed, dripping down onto the red bikini strings and her ass.

We stayed locked together, panting, my forehead against hers. She kissed me slow and deep, then smiled wickedly.

"Party's not over yet. I want you to fuck my ass next... but first, let's get back out there with your cum still leaking into my bikini."

I helped her fix the tiny suit under her dress, both of us grinning like idiots. The rest of the night was going to be torture—knowing her pussy was full of me, that red bikini soaked with our mess. Best office party ever.
