Curves in the Empty Gym

The moment I walked into the dimly lit yoga studio, my eyes locked on her thick, juicy ass stretching those black leggings to the breaking point. Sarah was the evening instructor, all soft curves and confident smiles, her chubby belly pressing gently against her sports bra as she rolled up mats. The gym was closing in ten minutes; we were the only two left after the last stragglers bolted. Tension crackled between us from the first lingering glance she gave my bulge during downward dog earlier.

"Hey, Mike," she said, voice low and teasing as she wiped sweat from her forehead. "Staying late to perfect your form? Or just hoping to catch me alone?"

I grinned, heart pounding. "Maybe both. You've got this way of making a guy forget the poses and focus on... other things."

She laughed, a rich, throaty sound that made her heavy tits jiggle. Her cheeks flushed pink under the fluorescent lights. "Flattery won't get you better alignment, but it might get you something else." She stepped closer, her hips swaying, that plump belly brushing my arm. The air smelled like lavender oil and her warm, feminine musk.

Before I could respond, she grabbed my hand and pulled me toward the mirrored wall. "Lock the door on your way over here." Her fingers were soft, a little damp from class. I flipped the bolt, pulse racing.

When I turned back, Sarah was peeling off her sports bra, freeing her massive, pendulous breasts. They swung heavy and full, nipples already hard as pebbles. "You've been staring at my body all night," she whispered, cupping one tit and lifting it like an offering. "Don't be shy now. Touch me."

I closed the distance fast, hands sinking into her warm, yielding flesh. Her chubby sides felt incredible under my palms, so soft and plush. I leaned down, sucking one fat nipple into my mouth while my other hand slid down to squeeze her thick thigh.

"Oh fuck, yes," she moaned, arching into me. "Suck harder... I love how you grab my fat like that."

Her hands tugged at my shorts, freeing my throbbing cock. It sprang out rock-hard, veins pulsing. Sarah's eyes widened with hungry approval. "Look at that big dick. Bet it feels even better than it looks." She dropped to her knees right there on the yoga mat, her chubby belly folding adorably as she gripped my shaft with both soft hands.

She licked the head first, swirling her tongue around the slit, tasting the precum leaking out. Then she took me deeper, her full lips stretching wide around my girth. The wet, slurping sounds echoed in the empty gym as she bobbed her head, chubby cheeks hollowing with each suck.

"God, Sarah... your mouth feels so fucking good," I groaned, threading fingers through her ponytail. She hummed around my cock, the vibration shooting straight to my balls. Drool spilled down her chin, dripping onto those massive tits.

She popped off with a gasp, strings of spit connecting her lips to my glistening dick. "I need this inside me. Now." Standing, she shoved her leggings down, revealing her shaved pussy nestled between thunder thighs, already slick and puffy. Her belly hung softly over her mound, making her look so deliciously ripe.

I spun her toward the mirror, bending her forward so her hands braced on the barre. That huge, round ass pushed back against me, cheeks spreading to show her tight pink hole and dripping cunt. I rubbed my cock along her slit, coating it in her juices.

"Quit teasing and fuck my fat pussy," she begged, wiggling those wide hips. I thrust in hard, burying every inch into her tight, velvety heat. She cried out, walls clenching around me like a fist.

The mirror showed everything: her tits swinging wildly, belly jiggling with each deep pound, my hands gripping handfuls of her soft hips. I fucked her fast, skin slapping loud against skin, her wetness coating my balls.

"Yes! Harder, Mike... make my chubby body shake!" she panted, pushing back to meet every stroke. I reached around, fingers finding her swollen clit, rubbing tight circles while I railed her.

Her first orgasm hit like a wave. She shuddered, pussy gushing around my cock, a low wail escaping her throat. "I'm cumming... oh shit, don't stop!"

I didn't. Instead I pulled out, flipped her onto her back on the thick mat, and climbed between her spread thighs. Her belly quivered as I slid back in, this time slower, grinding deep so my pelvis rubbed her clit. We kissed messily, tongues tangling while I rocked into her plush body.

Her hands roamed my back, nails digging in. "Fill me up... I want to feel your cum dripping out of me later."

The words pushed me over. I thrust faster, chasing it, her pussy fluttering around me again. With a deep groan I buried myself to the hilt and exploded, thick ropes of cum flooding her spasming cunt. She milked every drop, legs wrapped tight around my waist, both of us trembling.

We stayed like that, breathing hard, sweat cooling on our skin as the gym lights flickered toward shutdown. Sarah traced lazy circles on my chest, smiling up at me.

"Same time next week?" she asked, voice husky.

I kissed her softly. "Wouldn't miss it for the world."
