Linda had always been a hands-on mom, but after her divorce she started walking around the house in nothing but a thin tank top and panties. Her son Mark was nineteen, built from years of football, and home from college for the summer. One humid night she caught him staring at her heavy tits while she bent over the dishwasher.

Instead of scolding him she straightened up, nipples hard against the fabric, and said, "You like what you see, baby? Mom's been noticing how you look at her."
Mark didn't answer with words. He crossed the kitchen, grabbed her ass with both hands, and shoved his tongue into her mouth. Linda moaned and ground her crotch against the thick bulge in his shorts. "Fuck, you're hard for your own mother," she growled, reaching down to squeeze his cock through the denim. "Take it out. Let Mom see what she's been making stiff every night."
He yanked his shorts down. His cock sprang free, veiny and leaking. Linda dropped to her knees right there on the kitchen floor and wrapped her lips around the head. She sucked him deep, gagging when it hit the back of her throat, spit running down her chin onto her tank top. "That's it, fuck Mom's mouth," she said between slurps, jerking the shaft with one hand while her other hand rubbed her soaked panties. Mark held her hair and thrust, using her face like a toy.
They didn't make it to the bedroom. Linda stood, peeled off her panties, and bent over the kitchen table, spreading her legs. "Put it in me. Fuck your mother." Mark lined up and slammed home in one thrust. Her pussy was tight and wet, gripping him as he pounded her from behind. The table creaked with every stroke. Linda reached back and spread her ass cheeks so he could watch his cock disappear into her. "Deeper, you dirty boy. Fill Mommy's cunt."
Mark pulled out, spun her around, and lifted her onto the table. He shoved back inside, this time face to face, her legs wrapped around his waist. He sucked on her nipples through the tank top while he fucked her hard, balls slapping against her ass. Linda clawed his back and begged, "Don't stop. Mom needs that young cock. Come inside me." Mark grunted and unloaded, pumping thick ropes of cum deep into her pussy. She came with him, pussy pulsing and soaking his shaft.
They stayed locked together, breathing hard. Linda kissed him slow and dirty, tasting herself on his tongue. "We're not done," she whispered. She slid off the table, turned around again, and reached back to guide his still-hard cock to her asshole. "Mom wants it here too." Mark spit on her hole and pushed in, stretching her tight ring while she moaned and fingered her cum-filled pussy. He fucked her ass raw until he came again, flooding her bowels.
Later they moved to the couch. Linda rode him reverse cowgirl, tits bouncing, telling him exactly how she wanted her son to use her. Mark flipped her onto her back and ate her out, licking his own cum from her pussy before sliding back inside for another round. They fucked until the sun came up, switching positions, talking filthy the whole time.
By morning they were sticky and spent on the living room floor. Linda kissed his chest and said, "This is our secret now. Whenever you want Mom's holes, you take them." Mark smiled and slid two fingers into her well-used pussy. "Deal." They both knew the summer had only just begun.
