My Brother's Son sex story

My name is Claire, and at 32, I’m a woman who knows what she wants. Standing at 5’9” and weighing 130 pounds, I take pride in my toned, slender frame, always dressed in outfits that hug my curves just right. I love the way silk feels against my skin, the way a plunging neckline or a short hem can turn heads. My husband, Tom, is a taxi driver, working late nights, which leaves me alone in our cozy suburban home more often than I’d like. But last week, something happened that set my world ablaze—a night I’ll never forget, steeped in forbidden desire.

It was a warm Friday evening when my older brother, Mark, and his family came over for dinner. Laughter filled the house, and as the night wound down, I suggested that my nephew, Steven, stay over. He was 19, fresh out of high school, with a lanky build and a shy smile that hid a spark of curiosity. Mark agreed, and after they left, it was just Steven and me. Tom had already left for his night shift, the house quiet except for the hum of the TV.

I slipped into my favorite satin nightgown—a deep emerald green that clung to my curves, the hem barely reaching mid-thigh, with a lace-trimmed neckline that dipped low between my full breasts. The fabric was so thin it left little to the imagination, and I felt a thrill knowing Steven’s eyes would linger. We settled on the couch in the living room, flipping through channels, the glow of the TV casting shadows across the room. Steven sprawled out, his jeans and T-shirt casual, but I noticed his gaze drifting—not to the screen, but to my legs, exposed as I crossed them, letting the nightgown ride up just a bit.

“Finding anything good?” I asked, my voice teasing as I leaned back, letting my thigh brush against his.

“Uh, not really,” he mumbled, his cheeks flushing as he fumbled with the remote. The air between us crackled, and I couldn’t resist pushing further. I shifted, letting my legs part slightly, the nightgown sliding higher to reveal the edge of my black lace thong. His eyes darted down, then away, but not before I caught the hunger in them.

The TV landed on a late-night channel, one of those soft-core erotic films that always seem to play after midnight. A couple on screen was tangled in a steamy embrace, and I felt Steven tense beside me. “Oh, this looks… interesting,” I said with a playful smirk, watching him squirm.

“I, uh, I can change it,” he stammered, but his hand stayed frozen on the remote.

“No, leave it,” I said, my voice low. “It’s just a movie, right?” I stood, stretching languidly, knowing the nightgown would ride up even more. “I’m grabbing a drink. Want anything?”

“N-no, I’m good,” he said, his voice cracking. I sauntered to the kitchen, glancing back to catch him adjusting his jeans, his hand lingering over the growing bulge. My pulse quickened. This was dangerous, reckless—but the thrill was intoxicating.

When I returned, I stood behind the couch, leaning over so my breasts were inches from his shoulder. “So, Steven,” I purred, “what are you watching now?” The screen showed a woman moaning softly as her lover kissed her neck, and I saw his hand twitch, brushing against his erection.

“Nothing!” he blurted, his face scarlet as he tried to shift away. But I wasn’t letting him off that easily. I sat beside him, closer this time, my thigh pressing against his. My nightgown had slipped, revealing the full curve of my hip and the thin strap of my thong. His eyes flicked down, and I saw his cock strain against his jeans, the outline thick and unmistakable.

“Looks like you’re enjoying this,” I teased, nodding at the TV. “Don’t be shy. It’s normal, you know. Guys watch this stuff all the time.” I let my hand rest on his knee, my fingers tracing slow circles. “Ever watch anything like this before?”

He swallowed hard, nodding. “Y-yeah, sometimes.”

“Good,” I said, my voice a sultry whisper. “No need to be embarrassed.” I took his hand, guiding it to my chest, pressing his palm against my breast. My nipple hardened under his touch, and I let out a soft moan. “What do you think, Steven? Am I as sexy as those girls on TV?”

His breath hitched, his fingers trembling as he squeezed gently. “You’re… you’re gorgeous, Claire,” he managed, his voice thick with desire. “Sexier than anyone.”

I smiled, my hand sliding to his lap, brushing over his cock. It was rock-hard, pulsing under my fingers, and I gave it a slow stroke through his jeans. “Seems like you’re all grown up,” I said, my lips brushing his ear. “Ever been with a woman before?”

He shook his head, his eyes wide. “No… never.”

“Then let me be your first,” I whispered, my heart pounding. I stood, slipping the nightgown over my head, letting it pool on the floor. My breasts bounced free, full and firm, my nipples pink and erect. Steven’s jaw dropped, his gaze locked on my body as I hooked my thumbs into my thong, sliding it down to reveal my pussy—shaved smooth, already glistening with arousal.

“Touch me,” I said, guiding his hand to my breast again. He squeezed, his thumb brushing my nipple, and I moaned louder, encouraging him. “That’s it, Steven. Don’t be shy.” I pushed my breasts together, leaning forward so they brushed his lips. He hesitated, then took a nipple into his mouth, sucking eagerly, his tongue swirling. The sensation shot straight to my core, my pussy throbbing.

I reached for his jeans, unbuttoning them to free his cock. It sprang out, thick and long—easily eight inches, with a broad head and veins pulsing along the shaft. It was hot in my hand, and I stroked it slowly, feeling it twitch. “God, you’re so hard,” I murmured, kneeling between his legs. I licked the tip, tasting his salty precum, then took him into my mouth, sucking deeply as he groaned.

“Claire… oh, fuck,” he gasped, his hands tangling in my hair. I bobbed my head, my lips sliding over his cock, my tongue teasing the underside. My pussy was dripping now, aching to be touched. I stood, straddling him on the couch, and guided his hand to my clit. “Feel how wet I am,” I said, and he rubbed me clumsily, his fingers slipping inside my tight heat.

“You’re so… so wet,” he said, awestruck. I kissed him, our tongues tangling as I positioned his cock at my entrance. “I want you inside me,” I said, sinking down slowly. His cock stretched me, filling me completely, and I moaned as I began to ride him, my hips grinding against his.

“Fuck me, Steven,” I urged, my breasts bouncing as I moved. He grabbed my hips, thrusting up to meet me, his cock hitting deep inside. I leaned forward, pressing my breasts to his face, and he sucked my nipples, sending shivers through me. The room filled with the sounds of our bodies—wet slaps, moans, and the creak of the couch.

“I’m… I’m gonna come,” he panted, his thrusts growing erratic.

“Not yet,” I said, climbing off and turning around. “I want you to finish in my ass.” I bent over the couch, spreading my cheeks to reveal my tight, puckered hole. He hesitated, then pressed his cock against it, slick with my juices. He pushed in slowly, the stretch intense but delicious, and I moaned, “Harder, baby.”

He gripped my hips, thrusting faster, his cock filling my ass as I rubbed my clit, chasing my own release. “Come for me, Steven,” I gasped, and he did, his cock pulsing as he spilled deep inside me. My orgasm hit at the same time, my pussy clenching as waves of pleasure crashed over me.

We collapsed, panting, our bodies slick with sweat. “That was… incredible,” Steven said, his voice shaky.

I smiled, kissing him softly. “Our little secret,” I said, knowing this night would burn in my memory forever—a forbidden flame that lit up the dark.
