Mia had been fidgety all day.
She'd snapped at the renovation crew twice, barely touched lunch, and kept disappearing into the bathroom to stare at her phone calendar like it might have changed. By 7 p.m. she was pacing the bedroom in nothing but an oversized tank top, no panties, biting her lip raw.
"Three days late," she finally blurted, voice tight. "My period. It's never late."
Sophia didn't even blink. She'd already slipped out and returned with a discreet white paper bag. She dumped the contents onto the bottom bunk—three pregnancy tests, a bottle of lube, and that wicked little smile.
"Then we're doing this the proper way," she said calmly, already stripping out of her robe. "Mommy's rules. You two are going to take the tests together… while Alex fucks you both from behind. One cock, two pussies. We'll see exactly how scared—or excited—you really are."
Mia's eyes widened, but her pussy visibly clenched. A fresh trickle of wetness ran down her inner thigh. "You're insane, Mom. But… fuck yes."
Sophia arranged them perfectly. She bent Mia over the bottom bunk first, ass up, face pressed into the sheets. Then she climbed onto the bed beside her, mirroring the position—both women side by side, hips raised, legs spread, pussies glistening and ready. The pregnancy tests were lined up on the mattress right in front of their faces like little white judges.
I stood behind them, cock throbbing so hard it hurt. Sophia reached back and guided me in.
"Start with Mia," she ordered softly. "Slow and deep. Fill her while she pees on the stick. Then switch to Mommy. No pulling out until both tests are done."
I pushed into Mia first. She was soaked—nerves and horniness mixing into pure slick heat. One smooth thrust buried me to the hilt. She moaned loud and bratty, gripping the sheets.
"Fuck… he's so deep already," she gasped, reaching for the first test. "If I'm pregnant I'm blaming your huge loads, little bro."
Sophia handed her the stick, then grabbed the second one herself. "Pee now, princess. While he's still inside you. Mommy wants to feel every twitch."
Mia's pussy fluttered hard around me as she awkwardly held the test between her legs and let go. The soft hiss of her stream hitting the stick mixed with the wet slap of my hips against her ass. I kept fucking her slow and steady, grinding against her cervix on every stroke while the test developed.
Sophia watched with hungry eyes, already rubbing her own clit. "My turn. Switch."
I pulled out of Mia with a wet pop—thick strings of her cream connecting us—and slid straight into Sophia. Her experienced pussy welcomed me like velvet heat, hotter and somehow even tighter from the angle. She moaned low and maternal, holding her own test in place while I started thrusting.
"Both of you keep those sticks steady," she breathed, pushing back to meet my strokes. "We're going to watch the results together… while Alex keeps pumping."
The room filled with the filthy sounds of skin on skin, heavy breathing, and the occasional drip of my pre-cum and their juices onto the carpet. Mia's test developed first. One line. Negative. She let out a shaky laugh that turned into a moan as I slammed back into her for a few strokes, switching again like Sophia ordered.
Sophia's test developed next. One line. Negative.
Both of them stared at the results, relief flooding their faces… but something darker and hungrier replaced it almost instantly.
Mia looked back over her shoulder, eyes wild. "Negative… but fuck, the scare made me so wet. I almost wanted it to be positive. Imagine me walking around campus with your baby inside me while Mom teaches me how to hide it."
Sophia's pussy clamped down around me like a vice. She pushed back harder, voice husky. "Same, baby girl. The thought of my stepson breeding both of us… Mommy almost came just from the idea. Now fuck us properly. Celebrate the negative by filling us both until we're overflowing."
I didn't need telling twice.
I alternated—five hard thrusts into Mia, then five into Sophia—pounding them side by side while they kissed each other messily over the tests, tongues sliding, moaning into each other's mouths. Their pussies took turns milking me, competitive even now.
"Cum in me first," Mia demanded, pushing back. "I want the first celebratory load."
Sophia just smiled and reached between her own legs to rub Mia's clit. "Go ahead, princess. But Mommy's getting the second one straight after."
I buried myself in Mia and exploded—thick, heavy ropes pumping deep while the pregnancy scare still buzzed in our veins. She came with a loud cry, pussy spasming, pushing my cum out around my shaft in creamy waves. I switched immediately to Sophia and gave her the second load, just as promised—another massive flood that made her belly feel full and warm.
When I finally pulled out, both women stayed bent over, asses up, cum leaking down their thighs in thick white trails onto the sheets. Sophia reached back, scooped some from Mia's pussy, and licked it off her fingers with a satisfied hum.
"Negative," she whispered, eyes sparkling with fresh filth. "But the next time your period's even an hour late… we're doing this again. And maybe Mommy won't buy the tests so fast."
Mia grinned, still panting, and pulled me down for a messy three-way kiss.
"The scare made me hornier than ever. Tomorrow we're using toys. Mommy promised remote plugs for when Dad comes home for the weekend."
Sophia licked a stray drop of cum from Mia's lip and nodded.
"Training level: expert. The whole house is about to get a lot louder… and a lot riskier."
