This Shounen ga Otona ni Natta Natsu fanfic is a scorching, taboo-soaked fuckfest that’ll leave you dripping and depraved.

The rural summer heat chokes the old beach house, but it’s nothing compared to the fire igniting inside.  Taro, a lanky teen on the cusp of manhood, is stuck at his aunt’s seaside villa, bored out of his skull.  His older cousin, Reina, a tanned beach bunny with a body that screams trouble, has other plans.  She’s lounging on the porch, her bikini top barely holding her tits, a popsicle melting down her fingers as she eyes Taro like prey.  "Still a child, right?" she teases, licking the stick slow, her tongue flicking in ways that make his shorts tighten.

Reina doesn’t wait—she drags him inside, shoving him onto a creaky futon, her sun-kissed skin glistening with sweat.  “Time to grow up,” she growls, ripping his shirt off and straddling him, her soaked bikini bottom grinding against his throbbing cock.  With her pussy ready and yanking the ties loose, she sinks onto him and screams that shake the walls. It’s raw, relentless—creampies flooding her, her ahegao face howling as she claws his back raw, riding him like a tidal wave.

The screen door opens with a bang. It’s Reina’s best friend, Yuka, a goth surfer with piercings and a smirk, her wet wetsuit peeled halfway down, exposing inked tits.  “Fucking without me, Rei?”  she snarls, diving in.  She shoves Reina aside, mounting Taro’s face, her salty cunt smothering him as she grinds.  Reina’s not outdone—she grabs a vibe from her beach bag, cranking it up and plunging it into Yuka’s ass, sparking a three-way frenzy.  Oral, anal, fluids spraying—the futon’s soaked, the air thick with their screams.  Taro’s a toy in their hands, pounded by two older women who own every inch of him, their taboo summer lesson etching into his soul.
No innocence survives this heatwave—just raw, cousin-fueled debauchery in a beach house turned sex den.  X would lose it over this filthy chaos, no plot needed when the lust is this feral.
Dive in, you dirty fuck—this summer’s gonna burn.
