Mark had just turned twenty-one when it finally happened. He came home from college for the summer, and the house felt different with just the two of them. His mom, Diane, was forty-six, still fit from her morning runs, with full tits that strained against her tank tops and an ass that filled out her jeans like she was half her age. They had always been close, but the air had turned thick with something neither of them named.
One humid night after dinner, Diane poured them both whiskey. She sat on the couch in a thin robe that kept slipping open. Mark couldnt stop staring at the swell of her breasts, the dark nipples pushing against the fabric. You keep looking, she said, voice low and rough. You want to touch them?
He didnt answer with words. He moved over, pulled the robe open, and filled his hands with her heavy tits. Diane moaned, grabbed his hair, and pulled his mouth to her nipple. Suck it hard, baby. Just like that. His cock was already throbbing against his shorts. She reached down, freed it, and wrapped her fingers around the thick shaft. Fuck, youre big. Bigger than your dad ever was.
She dropped to her knees right there on the living room floor and took him into her mouth. No teasing, just wet, sloppy suction. Spit ran down his balls while she bobbed, gagging when she forced him into her throat. Mark held her head and fucked her face, watching her lips stretch around him. Thats it, Mom. Suck your sons cock.
Diane stood, shoved the robe off, and bent over the arm of the couch. She reached back and spread her ass cheeks, showing him her shaved, dripping pussy. Put it in. Fuck me like you mean it. Mark lined up and slammed home in one thrust. She was tight and hot, gripping him like a fist. He pounded her hard, the slap of skin loud in the quiet house. Diane pushed back, meeting every stroke. Deeper. Wreck that pussy. Its yours now.
They moved to her bed. She rode him, tits bouncing, grinding her clit against his pubic bone until she came with a hoarse shout, pussy pulsing around his cock. Mark flipped her onto her back, hooked her legs over his shoulders, and drove in deep. He fucked her with long, brutal strokes until his balls tightened and he flooded her cunt with thick ropes of cum.

Diane held him inside, milking every drop. Fill me up, son. Give Mommy all of it.
They didnt stop. Round two was slower but just as filthyhim eating her creampied pussy while she sucked him clean, then taking her ass while she fingered her clit and begged for more. By morning they were sore, sticky, and already planning the next night. The taboo only made every thrust, every moan, every load hotter. From then on, the house belonged to them.
