Cheating GF Seduced by BF's Best Friend - Forbidden Lust Erotic Story Part 1

I never planned to cheat on Mike. Not in a million years. We’d been together three years, shared an apartment in the heart of the city, and everyone said we were the perfect couple-him with his steady corporate job, me with my freelance graphic design gigs that let me work from home in yoga pants and oversized tees. At twenty-four, I thought I had it all figured out. But then Jake happened. Jake, Mike’s best friend since college, the one who was always around, always laughing that deep, rumbling laugh that vibrated straight through my chest and settled low in my belly like warm honey.
Part 1 begins on an ordinary Thursday evening, the kind where the summer air hangs thick and heavy outside our third-floor walk-up. The apartment smelled of the Thai takeout Mike had picked up on his way home-spicy basil and coconut milk, with that faint undercurrent of lemongrass that always made my mouth water. Our living room was bathed in the soft amber glow of the sunset filtering through the sheer linen curtains I’d hung last spring. The fabric moved lazily in the breeze from the open window, carrying in the distant hum of traffic and the sweet, floral scent of jasmine from the neighbor’s balcony planter.
I was curled up on the worn leather couch, legs tucked beneath me, wearing nothing but one of Mike’s old button-down shirts. The cotton was soft against my skin, the hem brushing the tops of my thighs, and every time I shifted, the fabric teased my bare pussy. I wasn’t wearing panties. I rarely did around the house anymore; it made me feel secretly naughty, even if Mike never noticed. My full C-cup breasts strained against the thin material, nipples already pebbled from the cool draft and the low thrum of anticipation I couldn’t quite name yet.
Mike was in the kitchen, unpacking the food, his back to me. He looked good in his rumpled dress shirt, sleeves rolled up to show the lean muscles of his forearms. “Babe, you want extra chili flakes?” he called, voice casual, affectionate.
“Yeah, please,” I answered, but my eyes weren’t on him. They were on Jake, who lounged in the oversized armchair across from me, long legs stretched out, one ankle crossed over the other. At twenty-seven, Jake was the kind of man who turned heads without trying-tall, broad-shouldered, with messy dark hair that always looked like he’d just run his fingers through it after a night of sin. His faded black tee hugged his chest, the fabric worn thin enough that I could see the faint outline of his nipples when he leaned forward. His jeans rode low on his hips, and when he shifted, the denim pulled tight over the bulge I swore I could feel in the air between us.
He caught me staring. Those hazel eyes-green flecked with gold-locked onto mine, and a slow, knowing smile curved his lips. “You okay, Soph?” His voice was lower than Mike’s, rougher around the edges, like gravel wrapped in velvet. It sent a warm flush creeping up my neck.
I swallowed hard, crossing my legs tighter. The movement made the shirt ride up, exposing the smooth, shaved skin of my inner thigh. I could smell myself already-a faint, sweet musk rising from between my legs, mixing with the Thai spices and the faint leather scent of the couch. “Yeah, just… tired from staring at screens all day,” I lied, forcing a smile.
Jake’s gaze dropped, just for a second, to the hem of the shirt where it barely covered me. He licked his bottom lip, slow and deliberate, and my pussy clenched involuntarily. A tiny pulse of heat bloomed there, slick and insistent. God, what was wrong with me? This was Mike’s best friend. The guy who’d been the third wheel on half our dates, the one who crashed on our couch after too many beers, the one who always brought me my favorite coffee-black with two sugars-without ever being asked.
Mike came back with the plates, oblivious, setting them on the coffee table with a clatter. “Dinner’s up. Jake, you staying for the game after?”
“Hell yeah,” Jake said, leaning forward to grab a fork. His knee brushed mine as he did, accidental, electric. The contact sent a spark straight to my clit. I bit the inside of my cheek to keep from gasping.
We ate like that-me sandwiched between the two of them on the couch now, the TV flickering with pre-game commentary. The room filled with the sounds of chewing, the occasional laugh, the low murmur of the announcers. But underneath it all, I was hyper-aware of everything. The way Jake’s thigh pressed against mine, warm and solid through his jeans. The clean, masculine scent of him-something woodsy and spicy, like sandalwood and fresh rain-mixing with Mike’s subtler cologne. The way my own arousal was building, slow and treacherous, making my inner thighs slick.
I shifted again, trying to ease the ache, but it only made the shirt ride higher. Cool air kissed my exposed pussy lips, and I felt a single drop of wetness trail down toward my ass. The smell of it-warm, feminine, faintly sweet like ripe peaches-hit me faintly. I wondered if Jake could smell it too. His nostrils flared once, subtly, and his eyes flicked to me again.
“You’re quiet tonight, Soph,” he murmured when Mike got up to grab beers from the fridge. His voice was just for me, low enough to feel like a caress against my ear. “Something on your mind?”
I turned my head. Our faces were inches apart. I could see the stubble on his jaw, the way his lips looked soft and full. “No,” I whispered. “Just… the heat, I guess.”
His hand rested on the couch cushion between us. His pinky brushed the side of my bare thigh, feather-light. “Yeah. It is getting hot in here.” The words hung there, heavy with double meaning. My breath hitched. My nipples tightened harder against the shirt, visible now as two dark points through the fabric.
Mike returned, handing out cold bottles. The condensation dripped onto my thigh where Jake’s finger had just been, icy against my flushed skin. I shivered, and Jake noticed. Of course he did.
The game started. Mike cheered at every play, completely absorbed. Jake pretended to watch, but his attention kept drifting back to me. Every time Mike’s eyes were glued to the screen, Jake would lean in closer-his shoulder brushing my arm, his breath warm against my neck as he whispered a joke only I could hear. Each little touch felt like a spark on dry tinder. My pussy was throbbing now, swollen and slick, the scent of my wetness stronger, mixing with the lingering Thai spices and the faint hoppy aroma of the beer.
I excused myself to the bathroom after the first quarter, needing air. The hallway was dim, lit only by the string lights I’d hung last Christmas. I closed the door behind me and leaned against the sink, staring at my reflection. My cheeks were flushed pink, lips parted, eyes glassy with unspoken need. I hiked the shirt up and looked down. My pussy was glistening, outer lips puffy and parted, inner folds shiny and pink. A thin string of arousal stretched from my clit to my thigh. I touched myself-just one slow swipe-and moaned softly at how wet I was. The scent bloomed stronger in the small space: sweet, musky, unmistakably aroused.
I washed my hands, splashed cold water on my face, and tried to compose myself. When I stepped back into the living room, Jake was alone on the couch. Mike had stepped out onto the tiny balcony for a quick call with his boss.
Jake patted the cushion beside him. “Come sit. Halftime’s boring without company.”
I hesitated, heart hammering, but I sat. Closer this time. Our thighs touched fully now, denim against bare skin. He didn’t move away. Instead, his hand-big, warm, calloused from weekend hikes-settled on my knee, casual as anything.
“You smell good tonight, Soph,” he said quietly, eyes on the TV but voice directed at me. “Like… peaches and something sweeter.”
My breath caught. He could smell me. The realization sent a fresh gush of wetness between my legs. I squeezed my thighs together, trapping his hand for a second. “Jake…” I started, voice barely a whisper.
His fingers flexed on my knee, sliding up an inch, under the hem of the shirt. “Shh. Mike’s right outside. Just… relax.”
His touch was electric. Slow, deliberate circles on my inner thigh, inching higher. The apartment smelled of everything at once now-the cooling Thai food, the faint leather of the couch, Jake’s spicy cologne, and me. My arousal. Thick and heady, filling the space between us like a secret.
I should have pushed his hand away. I should have stood up and gone to the balcony with Mike. Instead, I parted my legs just a fraction. His fingers brushed the slick heat of my pussy lips, and we both froze.
“Fuck, Soph,” he breathed, so low I felt it more than heard it. “You’re soaked.”
I bit my lip hard enough to taste copper. My clit pulsed under the lightest graze of his fingertip. He didn’t push inside-just traced the outer folds, spreading my wetness, teasing. The wet sound was tiny, obscene, lost under the TV noise. My nipples ached, breasts heavy and full, rising and falling with every shallow breath.
He pulled back just as Mike’s footsteps sounded on the balcony. His hand returned to his own lap, but not before he lifted his fingers to his nose, inhaling deeply, eyes locked on mine. The sight made my pussy clench hard, another drop of slick sliding out.
Mike came back in, none the wiser, cracking open another beer. “What’d I miss?”
“Nothing much,” Jake said smoothly, voice steady. But his eyes burned into me across the couch. “Just getting comfortable.”
The rest of the evening passed in a haze of tension. We watched the game. We laughed at the same jokes. Mike kissed my temple and called me his girl. But every time he looked away, Jake’s gaze devoured me-slow, hungry, promising. My body was on fire. My pussy stayed wet, throbbing, the scent of my need clinging to the air like perfume.
By the time Jake left at midnight, I was a mess. Mike pulled me into bed, sleepy and affectionate, sliding into me in the dark with gentle, familiar strokes. I came-quiet, quick-but it wasn’t enough. My mind was on Jake’s fingers, on that single teasing touch, on the way he’d smelled my arousal and looked like he wanted to devour me whole.
As Mike drifted off beside me, snoring softly, the apartment quiet except for the distant city hum, I lay there staring at the ceiling. The sheets smelled of us-sweat, sex, Mike’s cologne-but underneath it all, I could still catch the faint trace of Jake’s sandalwood on my skin where his hand had been.
This was only the beginning. I knew it in my bones. The slow burn had started, and I was already aching for more.
I woke the next morning to sunlight streaming through the bedroom window, painting golden patterns across the rumpled white sheets. The room smelled of morning-fresh coffee Mike had brewed before leaving for the office, mixed with the faint floral notes of my vanilla body lotion on the nightstand. My body felt heavy, languid, still humming from the night before. Between my legs, I was still slick, my pussy tender and swollen from the memory of Jake’s touch.
Mike had already gone. A note on the kitchen counter: “Early meeting, babe. Love you. Dinner tonight?” The apartment was mine until evening. And Jake… he had a habit of dropping by unannounced on Fridays, claiming he needed to borrow tools or drop off something Mike forgot.
I showered slowly, letting the hot water cascade over my skin. The steam filled the bathroom, fogging the mirror, carrying the coconut scent of my shampoo. I ran soapy hands over my breasts, thumbs circling my nipples until they peaked, then down to my pussy. I was so sensitive. One finger slipped inside easily, then two, curling against that spot that made my knees weak. I leaned against the tiled wall, legs spread, water pounding my clit as I fingered myself to thoughts of Jake-his fingers, his scent, the way he’d said my name like a dirty secret.
I came hard, gasping his name into the steam, thighs shaking. The orgasm left me breathless, but it only made the ache deeper. I wanted more. I wanted him.
Dressed in a loose tank top and tiny cotton shorts that barely covered my ass, I moved through the apartment. The living room still held traces of last night-the faint scent of Thai food in the trash, the indent on the couch where Jake had sat. I sat there, legs apart, and let my mind wander. My hand slipped under the waistband of my shorts, fingers circling my clit lazily as I replayed every brush, every look.
The knock came at 10:17 a.m. Sharp, confident. My heart slammed against my ribs.
I opened the door. Jake stood there in a gray tank top and gym shorts, hair still damp from his own shower. He smelled like fresh soap and that damn sandalwood. His eyes raked over me-tank top clinging to my braless tits, nipples obvious, shorts riding high on my thighs.
“Morning, Soph,” he said, voice husky. “Mike said I could grab the drill from the closet. Mind if I come in?”
I stepped aside, pulse racing. The door clicked shut behind him, and the air between us thickened instantly. The apartment smelled of my arousal already, faint but unmistakable, layered over the coffee and my lotion.
He didn’t go for the closet. He turned to face me in the narrow hallway, close enough that I could feel the heat radiating from his chest. “You been thinking about last night?” he asked, no games.
I nodded, unable to lie. My shorts felt damp already.
Jake stepped closer. His hand cupped my jaw, thumb stroking my lower lip. “Good. Because I haven’t stopped.”
His mouth hovered over mine. Not kissing. Not yet. Just breathing me in. My pussy throbbed, a fresh wave of wetness soaking the crotch of my shorts. The scent bloomed-peaches and sin.
“Jake… we can’t,” I whispered, even as my body leaned into him.
“I know,” he murmured. But his other hand slid down my side, over my hip, and cupped my ass, pulling me against the hard ridge in his shorts. “Tell me to stop, Soph. Say it.”
I couldn’t. My hips rolled against him instead, grinding my soaked pussy along his length through the thin fabric. A low groan escaped him.
The tension crackled like electricity. This was the edge-the slow, delicious build before everything shattered. My body was alive, every nerve singing, the apartment filled with the scent of my need and his growing hunger.
And we hadn’t even kissed yet.
