The steam from the hot shower filled the massive master bathroom, fogging up the floor-to-ceiling mirrors and turning the air thick and humid. Water cascaded from the rainfall showerhead like a tropical downpour, drumming against the marble tiles. Sophia led the way, her naked curves glistening as she stepped under the spray first—water tracing rivulets down her full natural tits, over her soft belly, and dripping from her trimmed pussy. Her wavy brunette hair clung wetly to her back, blue eyes half-lidded with lingering lust as she beckoned us in.
"Come on, you two," she purred, voice echoing slightly off the walls. "We got all sweaty again. Time to clean up... or get dirtier."
Ava giggled, her slim pale body slipping past me, freckles standing out against flushed skin. Her small ass jiggled as she stepped in, wavy red hair darkening under the water, turning into slick strands that framed her cute face. She pressed against Sophia immediately, their bodies sliding together—tits mashing, hands roaming. Ava's fingers teased Sophia's hard nipples, pinching and pulling while Sophia's hand dipped between Ava's thighs, rubbing her slick folds.
I followed, cock already throbbing hard again, the hot water hitting my skin like a lover's touch. The contrast of the steam and the cool air outside made every sensation sharper—the way water beaded on their skin, the scent of body wash mixing with their arousal, sharp and musky.
Sophia turned to me, pulling me under the spray with them. "Your stepsister wants to ride you, Ethan. Don't make her wait."
Ava didn't hesitate. She pushed me against the tiled wall, the cool surface shocking against my back as her hot mouth crashed into mine. Her tongue invaded hungrily, tasting of cum and sweetness from earlier. Her small hand wrapped around my shaft, stroking under the water—slick, firm pumps that had me groaning into her mouth.
"Fuck me, stepbro," she whispered against my lips, voice breathy and demanding. "I need your big cock inside me again. Fill me up... breed me like a good little slut."
The breeding talk sent fire through my veins. I grabbed her slim waist, lifting her effortlessly—her tall legs wrapping around me, pale thighs clamping tight. Sophia watched, soapy hands massaging her own tits, pinching nipples as she fingered herself slowly. "That's it, sweetie. Pound your stepsister's tight pussy. Make her scream."
I thrust up into Ava hard, no warning—her outie pussy swallowing me whole, walls clenching hot and wet around my length. The water made everything slicker, louder—wet slaps echoing as I bounced her on my cock, her small tits bouncing against my chest. She cried out, nails digging into my shoulders, head thrown back as rain poured over us.
"Oh God, yes! Harder... own me!" Ava begged, her voice high and needy. I obliged—rough, possessive thrusts, one hand tangling in her wet red hair, yanking her head back to expose her neck. I bit down, sucking marks into her pale skin while pounding deeper, hitting her cervix with each slam.
Sophia pressed in from behind Ava, her full tits squishing against Ava's back. Her hands reached around— one fondling Ava's clit in furious circles, the other teasing my balls, rolling and tugging. "Good girl... take your stepbrother's cock. Feel how he stretches you? He's going to cum so deep inside."
Ava came first—hard, body convulsing, pussy squirting around my shaft in hot spurts mixed with the shower water. Overstimulation hit her fast; she whimpered, trembling, but didn't stop grinding down. "Don't stop... more... make me cum again!"
I spun her around, bending her over—hands braced on the wall, ass up. Doggystyle under the spray, I railed her relentlessly, spanking her cute little butt until it glowed pink, water splashing with each impact. Sophia knelt beside us, tongue darting out to lick where we joined—lapping at Ava's clit, then my shaft as it pistoned in and out, tasting our mixed juices.
"Fuck, Mom... your tongue..." Ava moaned, pushing back.
Sophia stood, pressing her body against mine from the side. "My turn soon. But first... watch him breed her."
The possessiveness surged—I gripped Ava's hips bruisingly, thrusting like an animal. "You're mine, stepsis. This pussy belongs to me now." I growled, feeling my balls tighten.
"Cum inside me! Breed your little slut!" Ava screamed, another orgasm ripping through her.
I exploded—thick ropes flooding her depths, overflowing as I kept pumping, breeding talk turning real in the heat. Cum leaked out, washed away by the water, but the feeling lingered.
Panting, I pulled out. Ava turned weakly, dropping to her knees with Sophia. Double blowjob cleanup—both tongues laving my sensitive cock, sucking off our combined mess. Ava deepthroated first, gagging cutely, while Sophia licked my balls, humming praise.
Then Sophia stood, pushing me to sit on the built-in bench. "Ride me reverse, baby girl," she told Ava, but no— she wanted me. Sophia straddled me cowgirl, sinking down on my still-hard cock with a satisfied moan. Her MILF pussy gripped differently—experienced, milking me as she bounced, tits swaying in my face.
I sucked her nipples hard, biting, while Ava knelt behind her, fingering Sophia's ass and rubbing her clit. "Fuck her harder, Ethan. Make Mom cum all over your cock."
Sophia rode faster, grinding deep, water cascading over us. "Yes... fill your stepmom up too. Breed me, sweetie... give me everything."
Jealousy flickered in Ava's eyes—possessive, yandere glint—as she bit Sophia's shoulder. "He's mine first..."
But it only fueled the heat. Sophia came screaming, pussy spasming, squirting down my shaft. I followed, pumping another load deep inside her.
We collapsed under the cooling water, tangled limbs, kisses shared lazily. But as the steam cleared, Sophia's phone buzzed from the counter—Dad's name on the screen, saying he'd be home early from his trip tomorrow.
A thrill of risk shot through us. Ava's hand stroked me again. "We have all night... and maybe more."
The forbidden craving only grew stronger.
