Lisa lounged by the sparkling backyard pool, the sun kissing her golden-tanned skin like a lover who couldn't get enough. At 42, she was a walking wet dream—curves that could stop traffic, with a pair of massive, gravity-defying tits that strained against any bikini top she bothered to wear. Today, though? No top at all. Just tiny black thong bottoms that barely contained her plump, juicy ass. She arched her back, letting the rays soak into her bare 36DD melons, nipples hardening into fat pink cherries under the heat. Life was good since marrying Jake's dad six months ago. The house was hers to rule, the pool was private, and the divorce settlement meant she never had to work again. Little did she know, her new stepson was about to make things a whole lot more interesting.

From behind the patio door, 19-year-old Jake peeked out, his heart pounding like a jackhammer. College break had him home alone most days—Dad was always traveling for work—and spying on his busty stepmom had become his dirtiest habit. God, she was stacked. Those tits jiggled with every breath, and the way her thong rode up between her thick cheeks had his swim trunks tenting obscenely. At 6'2" and built from years of soccer, Jake was no scrawny kid, but right now, his massive erection—nine thick inches of throbbing young meat—was the star of the show, straining the fabric like it was about to rip free. He adjusted it futilely, biting his lip as Lisa shifted, squeezing her thighs together in a way that screamed she was feeling frisky too.

Lisa's eyes flicked open behind her oversized sunglasses, catching the flash of movement. A grin spread across her glossy lips. Busted. Instead of covering up or yelling, she propped herself on one elbow, those monster tits swaying hypnotically. "Jake, honey? You gonna stand there gawking all day, or come out and join your stepmommy for some sun?"

Jake froze, face burning hotter than the pavement. "Uh... shit, sorry, Lisa. I didn't mean—"

She laughed, a throaty, sexy sound that went straight to his balls. "Oh, please. Don't apologize for appreciating the view. But sweetie, if you're gonna spy, at least do it up close." She patted the lounge chair beside her, eyes dropping shamelessly to the massive bulge tenting his trunks. "Looks like you've got a real 'growing problem' there. Poor baby must be so uncomfortable."

Jake stepped out, cock twitching at her words, the outline so clear it was practically waving hello. He sat awkwardly, trying to angle away, but Lisa wasn't having it. She eyed that bulge hungrily, licking her lips. "Mmm, that's no little boy boner. You've grown into quite the man since I moved in. Bet the girls at college are lining up for a ride on that monster."

"Lisa, I—" He stammered, but she cut him off with a wink, her voice dripping with playful filth.

"Tell you what, stud. Stepmommy needs some sunscreen. These big girls burn easy." She squirted a generous glob of lotion into her palm, rubbing it teasingly between her hands before slathering it over her massive tits. Jake's eyes bugged out as she massaged them, pinching her nipples until they stood at attention. "Wanna help? Rub it in good for me?"

ESCALATION

Jake's mouth went dry, but his dick answered for him, jerking visibly in his trunks. "Y-yeah, okay." He knelt beside her, hands shaking as he took the bottle. Lisa lay back, arching to present her oiled-up tits like a feast. He poured lotion over them, the white cream trickling down her cleavage, and started rubbing—tentative at first, then bolder, kneading those soft, heavy orbs. Her skin was slick and warm, nipples diamond-hard under his palms.

"Mmm, that's it, Jake. Get every inch. Fuck, your hands are strong." Lisa moaned softly, her breath hitching. Emboldened, she rolled onto her stomach, peeling her thong aside just enough to expose her plump ass cheeks. "Don't forget the back, baby. And make it thorough."

Jake's cock was a steel rod now, leaking pre-cum that soaked a dark spot on his trunks. He squirted lotion onto her ass, spreading it in wide circles, thumbs dipping dangerously close to her crack. Lisa pushed back, grinding her oiled cheeks right against his bulge. "Oops," she giggled, wiggling playfully. "Feels like you're packing heat down there. That thing's gonna poke a hole through your shorts."
