55yo Big Bottom Step-Aunt Diana Catches Step-Nephew Jerking Off

Jason had the house to himself—or so he thought. His step-aunt Diana was supposed to be out running errands all afternoon. The 22-year-old was crashing at her place while his parents renovated their kitchen. Bored and horny, he retreated to the guest bedroom with his phone.
He scrolled through some old bookmarks, landed on a video of a thick mature blonde getting railed. His shorts were down in seconds. He spat in his palm, wrapped it around his cock, and started stroking slow at first. The room smelled like laundry detergent and yesterday’s pizza. The ceiling fan clicked overhead.
He sped up, eyes glued to the screen. Skin slapped on the tiny speaker. He bit his lip to stay quiet.
The door creaked open.
Diana stood there in her usual Saturday outfit: tight black leggings hugging her wide hips and big round ass, a loose white tank top, no bra so her heavy tits swayed when she moved. Blonde hair pulled back in a messy ponytail. She was holding a grocery bag in one hand.
She froze. Jason froze. His hand still on his dick, mid-stroke.
“Jason?” Her voice was low, surprised but not angry. “What the hell are you doing?”
He yanked the blanket over his lap, face burning. “Shit—Aunt Di—I thought you were gone—”
She set the bag on the dresser. Didn’t leave. Just closed the door behind her with a soft click. The TV in the living room droned some home renovation show in the background.
Diana tilted her head, eyes dropping to the tented blanket. “You were jerking off to porn in my house?”
“I… yeah. Sorry. I didn’t mean—”
She stepped closer. Her perfume hit him—something cheap and floral mixed with the faint sweat from walking. At 55, she carried extra weight in all the right places: thick thighs, soft belly, that massive ass that jiggled when she walked.
She smirked. “Been a long time since anyone’s looked at me like that.”
Jason swallowed. “What?”
“You heard me.” She tugged the blanket down slowly. His cock sprang free, still hard, tip shiny with precum. “Look at you. All worked up.”
He didn’t cover himself. Couldn’t. Her eyes locked on it.
Diana licked her lips. “You want some help with that, nephew?”
His brain short-circuited. “Aunt Di…”
“Shh.” She dropped to her knees beside the bed. The carpet was old and scratchy. She reached out, wrapped her fingers around him. Her hand was warm, a little rough from years of housework. “Been too damn long since I had a cock in my mouth.”
She leaned in. Her breath was hot on his skin. Then her lips closed around the head. She sucked slow, tongue swirling. Jason groaned, head falling back against the headboard.
“Fuck…” he whispered.
She popped off for a second. “Quiet. Neighbors might hear.” Then she went deeper, cheeks hollowing. Saliva dripped down his shaft. She bobbed her head, messy and eager. One hand cupped his balls, rolling them gently.
Jason tangled his fingers in her blonde hair. Not pulling—just holding on. She hummed around him, the vibration making his toes curl.
After a minute she pulled back, strings of spit connecting her lips to his cock. “You like that?”
“Yeah… God yes.”
She stood up, turned around. Bent over slightly, hands on her knees. That big ass pushed out toward him. She peeled the leggings down slow. No panties. Just bare skin, pale with a few stretch marks, and a thick bush of blonde hair between her legs.
“Help me with these,” she said.
He sat up fast, shoved the leggings the rest of the way down. She kicked them off. Then she climbed onto the bed, straddling his lap backward. Her ass cheeks spread as she lowered herself. He could smell her—musky, aroused.
She reached back, guided his cock to her entrance. Wet. Hot. She sank down with a long sigh.
“Ohhh fuck,” she breathed. “Been too long.”
Jason grabbed her hips. Soft flesh overflowed his fingers. She started rocking, slow at first. Her ass bounced against his thighs. The bed creaked.
She leaned forward, hands on his shins for balance. That gave him a perfect view of her pussy swallowing his cock. Pink lips stretched around him, slick and shiny.
“Faster,” he grunted.
Diana picked up speed. Skin slapped skin. Loud. Wet. She moaned low in her throat. “Harder, baby. Fuck your aunt’s pussy.”
He thrust up to meet her. The headboard banged the wall once—twice. She laughed breathlessly. “Careful. Don’t break it.”
But she didn’t stop. She rode him harder. Sweat beaded on her back. Her tits swung under the tank top. He reached around, squeezed one. Nipple hard against his palm.
She straightened up, grinding in circles. “Touch my ass. Grab it.”
He did. Spread her cheeks. Watched his cock disappear inside her again and again.
Diana reached down, rubbed her clit. Fast circles. Her breathing turned ragged. “I’m gonna come… fuck… don’t stop…”
Her pussy clenched around him. She shuddered, thighs shaking. A low, guttural moan escaped her. “Oh God… yes…”
Jason felt it building. “Aunt Di… I’m close…”
She lifted off him quick. Spun around. Dropped back to her knees. “In my mouth. Give it to me.”
She sucked him deep again. Hand pumping the base. Tongue flicking the underside. Jason’s hips jerked.
“Fuck—coming—”
He exploded. Thick ropes shot across her tongue. She kept sucking, swallowing what she could. The rest spilled out, dripping down her chin. She milked him until he was spent.
Diana sat back on her heels. Cum streaked her lips and cheek. She wiped her mouth with the back of her hand, grinning. “Messy boy.”
Jason panted. “Holy shit.”
She stood up, pulled her leggings back on. Cum still on her face. She didn’t wipe it off yet. “Oven timer’s gonna go off soon. I got cookies in there.”
He blinked. Reality crashed back. The TV still murmured in the other room. A car passed outside.
Diana leaned down, kissed his forehead. “Next time you wanna jerk off, come find me first. Save us both the trouble.”
She walked out, hips swaying. Left the door cracked.
Jason lay there, shorts around his ankles, staring at the ceiling. The fan kept clicking.
He heard the oven beep in the kitchen.
Life went on.
