Sarah slammed the door behind her, her tits heaving under the thin tank top as she stormed into the living room. Her son had come home bruised again from that cocky asshole Derek, the 20-year-old college jock who lived down the block. At 42, Sarah was done playing nice. She marched over to Derek's place, ready to rip him a new one.
Derek opened the door shirtless, his muscles glistening with sweat from a workout. "Mrs. Thompson? What the fuck do you want?"
"You little shit, stay away from my boy," she spat, pushing past him into the house. Her ass swayed in tight yoga pants as she turned to face him. "He's 19 and doesn't need your bullying bullshit."
Derek smirked, eyes dropping to her hard nipples poking through the fabric. "Or what? You gonna punish me?"
The tension snapped. Sarah grabbed his belt, yanking it open. "Yeah, I'm gonna fuck that attitude right out of you." She dropped to her knees, hauling out his thick cock. It was already half-hard, veiny and heavy in her hand. She spat on it and started stroking, then swallowed the head, sucking hard and sloppy.
"Fuck yes, bully mom," Derek groaned, gripping her hair. "Suck that dick like you mean it."
Sarah gagged herself deeper, drool running down his shaft as she bobbed fast. Her free hand slipped into her pants, fingering her wet pussy. She pulled off with a pop. "Get on the couch. I'm riding this cock."
Derek stripped her tank top off, mauling her full tits, pinching the nipples until she moaned. She shoved her pants down and climbed on, lining his fat dick up with her slick cunt. She sank down inch by inch, stretching around him. "Goddamn, you're big. Fill me up, you bastard."
She rode him raw, slamming her hips down, her ass slapping against his thighs. Derek thrust up to meet her, pounding her pussy hard. "Take it, you dirty mom slut. Your son's bully is balls-deep in you."
Sarah leaned forward, feeding him a tit to suck while she ground her clit against him.

Sweat slicked their bodies. She came first, pussy clenching tight, juices soaking his cock. Derek flipped her onto her back, spreading her legs wide and hammering in. The wet sounds of fucking filled the room as he railed her through another orgasm.
He pulled out, flipped her onto all fours, and drove back in from behind. His hands gripped her hips, slapping her ass red while he fucked her deep and dirty. "Gonna fill this bully mom pussy," he grunted, unloading hot cum inside her with thick pulses.
They collapsed, breathing hard. Sarah smiled wickedly over her shoulder. "Same time tomorrow, or I tell everyone what a pussy you really are." Derek just laughed and slapped her ass again, already getting hard for round two.
