The door slammed shut behind Mark, and Linda knew her life had changed forever. At 42, she still had the body that made men starefull tits, wide hips, a thick ass that jiggled when she walked. But her 19-year-old son had just come home from college with a new plan.
"Strip, Mom," he said, dropping his bag. His eyes were hard. "From now on, you're my free-use slut. No more pretending. You cook, you clean, and you spread whenever I want that pussy or that mouth."
Linda's face burned, but her nipples tightened under her blouse. She had caught him jerking off to her pictures last month. Now he was calling her bluff. "Mark, this is wrong"
He grabbed her hair and yanked her close. "Wrong is you walking around in those tight shorts knowing what it does to me. Now get naked or I tell Dad about the vibrator you hide in the laundry."
Her hands shook as she unbuttoned her blouse. Tits spilled out, heavy and bare. She pushed her jeans down, then her soaked panties.
Mark stared at her shaved cunt. "On your knees. Suck your son's cock like the slut you are."
She dropped. His dick was thick and already leaking. Linda opened her mouth and took him deep, gagging as he fucked her throat. Spit ran down her chin onto her tits. He held her head and pumped until he flooded her mouth. "Swallow every drop, Mom. Good slut."
That night he bent her over the kitchen table after dinner. "Spread your ass." He slammed into her pussy without warning, pounding hard while she moaned and begged. "Harder, babyfuck your mom's cunt." He came inside her, then made her sit with his load leaking down her thighs while they watched TV.
Every morning she woke to his cock in her mouth. "Free use means anytime," he reminded her, pulling her onto his lap in the living room. She rode him reverse, ass bouncing, while he slapped her cheeks red. "Tell me you're my slut."
"I'm your slut, Mark. Your free mom slut."
He used every hole. One afternoon he bent her over the bathroom sink and worked her ass open with spit and fingers before sinking his cock in. Linda screamed and came so hard her legs gave out. He held her up and kept fucking until he pumped cum deep in her bowels.
Weeks blurred into constant use. She stopped wearing panties around the house. When he wanted her, he just bent her over whatever was closestcouch, counter, washing machine. Sometimes he made her crawl and beg. "Please fuck your mom's pussy, son. I need it."
He invited a friend over once. Linda served them naked, then got fucked by both while Mark watched and stroked. "That's it, Mom. Show him how much of a slut you are for me." She came with two cocks stretching her, dripping and shameless.
By the end of the summer, Linda didn't wait to be told. She walked into his room at night, climbed on, and rode him slow and deep, whispering filthy things. "Your cum belongs in me. Fill your free-use mom again."
Mark smiled, grabbed her hips, and gave her exactly what she craved. She was his nowcompletely, openly, and dripping with satisfaction.
