Chapter 1: Teasing Thresholds
Sarah lounged on the velvet couch in her silk robe, which she let slip open just enough to reveal the sheer black panties hugging her ass. Her son Mark entered the room, backpack slung over one shoulder, and froze at the sight.
"Well, if it isn't my favorite horny boy," she purred, crossing her legs slowly. "Home from college and already staring like you've never seen a real woman before."
Mark smirked, dropping his bag. "Mom, those panties are a crime. You're dripping temptation and you know it."
"Dripping? Only if you earn it, sweetheart. Come closer and tell me why that cock of yours is already hard in your jeans." She uncrossed her legs, letting the robe fall wider. "Or are you all talk and no thrust?"
He stepped forward, voice sharp with wit. "Because every time you tease like this, I imagine bending you over and claiming what you've been promising. But you're the depraved one here, aren't you?"
Sarah laughed, low and throaty, pulling him down beside her. "Depraved? Darling, I'm just honest. Now kiss me before I decide you're not worth the effort." Their lips met fiercely, her hands roaming to free his throbbing cock. She stroked it with expert fingers, whispering, "Look how hard you are for mommy's pussy."
Mark groaned, panting as she slid lower, taking him into her mouth for a slow, wicked blowjob. "Fuck, Mom... your tongue is lethal."
She released him with a wet pop, eyes gleaming. "Lethal enough to make you cum quick? Not yet." Rising, she straddled his lap, grinding her wet, dripping pussy against him. "Feel that? All for you. But first... watch." With a teasing grin, she let a warm stream of piss trickle over his cock, marking him in their private depravity. "Now you're really mine."
Mark's hands gripped her ass firmly. "You're strong, I'll give you that. But I'm not backing down." He flipped her gently onto the couch, positioning himself. Sweating and horny beyond reason, he eased his cock into her tight ass, thrusting deep as she moaned commands. "Harder, boy—own it like you mean it."
Their bodies moved in frantic rhythm, her strong legs locking around him, both panting and sweating as pleasure built. She came first with a sharp cry, her pussy clenching, then he followed, flooding her with hot cum. The room echoed with their shared gasps, the taboo heat leaving them entwined and breathless.
