I knew the second I walked in—she didn't want me there. My sister never could hide her feelings, especially the nasty ones. But I wasn't here for her. I was here to escape our dead-end town after finishing high school. Tomorrow was about college visits. Tonight? Just surviving in the same space as her and her boyfriend.

I noticed the tension between them right away. It didn't take a genius to figure out things were off, and I'm pretty sure Drew had been sleeping in the guest room before I showed up. When I was unpacking my stuff, I found his clothes in the dresser—like he'd been staying there for a while. But now that I was here, he was forced back into their bedroom.

I never got what Drew saw in my sister. She was constantly on his case about 'getting a better job,' even though he'd paid for her fancy law school while I'd be settling for community college. Now that she was some big-shot attorney, she acted like he wasn't good enough just because he worked as a construction foreman. It was a solid job, paid well, but in her eyes, that didn't cut it.

Drew was tall, fit, and way too good-looking for a guy in his thirties. He was hot—like stupid hot.

I could tell Drew was into me, and I'd be lying if I said I wasn't curious. I'd caught him staring at me more than once, and honestly, I wasn't mad about it. With my sister acting like such a bitch to both of us, I figured, why not push things a little?

As I sauntered into the living room, my short skirt swayed with every step, my tank top hugging my curves, my long blond hair flowing down my back. I wasn't wearing a bra, and I could feel my nipples pressing against the thin fabric. I didn't have to look to know Drew's eyes were on me.

They sat on opposite ends of the couch, a wide gap between them, pretending to watch TV. My sister was dressed in a red cocktail dress, and Drew was in his shorts and a T-shirt. The tension was thick, as if they just had an argument.

I slid in next to Drew, letting my thigh press against his. Casually, I draped a blanket over us, covering his lap. I took a chance, placing my hand on his muscular thigh. Drew looked at me, surprised, but he did not move away. The way his smoldering gaze met mine told me everything I needed to know.

With a naughty smile, I boldly placed my hand on his lap, tracing my fingers along his hardening bulge. A thrill rushed through me as I realized he was just as turned on as I was. As my fingers wrapped around his shaft, it twitched against my palm. My sister was sitting right next to us, unaware that I was stroking her boyfriend's cock.

He stiffened under my touch as I slowly jerked him off and I couldn't help but smile to myself, knowing that I had him right where I wanted him. My hand glided up and down his length, teasing him into a full erection, throbbing with anticipation at the mercy of my playful strokes.

My sister stood up, and I froze, my hand clutching her boyfriend's aroused bulge. She murmured that it was time to go out for a business dinner, but the dress was way too slutty. I suspected she was screwing her boss to get promoted so fast. It was the only thing that made sense. And I had a feeling Drew thought the same thing, which explained the fights and why he was giving in to me so easily.

Once my sister was gone, I pulled away, got up, and settled myself on the floor, kneeling between his legs. The look on his face was a mix of surprise and excitement as I grabbed the edges of his shorts, pulling them off, along with his boxers, revealing his rigid, precum leaking member.

Taking my time, I licked my lips before leaning in and swirling my tongue around his cock's head. His hand gripped the edge of the couch, his hips instinctively bucking up, making me giggle. I met his gaze as I licked off his salty pre-cum and then drew slow, wet licks along the firm, hot flesh, all the way down to his balls.

My hand glided up and down his saliva-coated manhood as I gently sucked his balls into my mouth, massaging them with my tongue, savoring their weight and texture. With deliberate sloppiness, I trailed my tongue back up, teasing and licking until I reached the tip of his pulsating rod.

His eyes widened as I sucked his bulbous glans into my mouth, my lips forming a tight seal around him as I slowly descended on his straining sex. My gaze locked with his, my throat welcoming his length, and I relished the sensation, despite the momentary choke.

I pushed harder, my tongue tracing through every curve of his firm flesh. Drew strained to maintain control, but his body betrayed his mounting need, his cock twitching against my palate. My mouth moved faster, engulfing his length until my lips touched the base of his shaft and his pubic hair tickled my nose.

His pupils were dilated with lust, reflecting his loss of control. He grasped my hair, holding me in place, his breath ragged as he tried to delay the inevitable. I could feel his desire swelling, my throat tightening around him as he was desperately trying not to cum.

The intensity made my eyes water, but I didn't pull back. I wanted to taste his sperm, so I fought the gag reflex that threatened to force him out. Drew looked torn, seeing his dick buried in my mouth, caught between shooting his load and feeling guilty for cheating on his girl with her sister.

"I want to fuck your pussy so badly," he groaned.

His grip on my hair loosened, and I pulled back, gasping for air. A mischievous smile played on my lips as I rose to my feet, my eyes locked on his. Without breaking eye contact, I stripped off my top, revealing my petite, firm breasts. My nipples, sensitive to his scorching stare, tightened into hard beads, craving his touch.

His intense gaze remained fixed on mine as my hands reached for the waistband of my skirt. With a slow motion, I slid it down my hips, letting it pool at my feet. His eyes roamed, taking in every exposed inch of my body, my heart pounding in response. A flush creeped up my neck, but I refused to break eye contact, daring him to witness my all of my vulnerability.

My fingers hooked into the sides of my lace thongs and drew them down my thighs, exposing my bare, swollen folds. Stepping out of them, I noticed his eyes darken with desire as they feasted on my glistening, puffy labia, proof to the pleasure we were both craving.

His eyes followed my every move as I straddled him. He gripped my ass, guiding my hips lower until his thickness teased my wet entrance. I inhaled sharply as he filled me up, his cock sliding home, inch by inch, into my hot, eager core.

I bit down on my lower lip, letting out a moan as I relished the feeling of his iron-hard masculinity buried deep within me. The sensation of my sister's boyfriend's bare cock inside me was simply electrifying.

Drew leaned forward, capturing my rose-red nipple between his lips, sucking and teasing it with his teeth. I ground my hips, my sensitive bud rubbing against his pubic bone, seeking the friction that would tip me over into ecstasy.

He pulled away, leaving me wanting, and I whimpered, craving the sensation of his wet tongue on my sensitive peak. The wicked grin on his face spoke volumes about his enjoyment of our forbidden encounter. It was so wrong, yet so irresistible.

With his hands firmly on my hips, Drew whispered, "Your pussy is unbelievably tight. So wet for me."

I urged him on with a ravenous moan, "Please, fuck me," as I pressed my lips feverishly against his, my fingers clutching his shoulders.

Our tongues danced wildly as I rode him, our kiss passionate and famished. He thrust powerfully, pounding into my core, driving me closer to the edge.

I whispered in his ear, "Cum inside. I'm on the pill."

His muscular hands clutched my hips, guiding my movements as I pressed down to meet his every upward possessive thrust. My body trembled with pulsating heat as my climax exploded, my pussy convulsing around his cock, triggering his release. His warm seed filled me, my walls milking him, desperate to hold on to him, prolonging the euphoric sensation.

My breasts pressed against his chest as I nestled my cheek on his shoulder, both of us catching our breath. The warmth of his skin calmed the exhilaration coursing through me, and for a brief moment, everything seemed still.

We stayed entwined, arms wrapped around each other, until his cock lost some of its vigor. I stood up, his cum trickling down my thigh, the sight eliciting a mischievous grin from Drew.

"See you at breakfast," I said with a playful wink as I grabbed my clothes and headed to the bathroom.

After a quick shower, washing away any trace of what had just happened, I got dressed and slipped into the guest room.

My sister would never know, and I couldn't help but smile to myself, knowing Drew would think of me every time he looked at her.
