Dad's voice carried clearly from his office down the hall—confident and smooth, in full presentation mode to twenty executives on a global video call.
"…and as you can see on slide twelve, the projected Q4 growth—"
Sophia left the master bedroom door wide open. Morning light poured in. The marital bed was still warm and stained from yesterday. She was already naked, heavy breasts swaying as she lubed the thick double-ended dildo and set her phone on the nightstand for 4K recording.
"Final boss round," she whispered, her voice carrying just enough to heighten the risk. "Door stays open. Dad's mic is live. We fuck each other on this bed while he presents. Whoever makes Alex cum the hardest while he's mid-sentence wins the entire two-week training arc. Loser wears both our creampies under her dress to the airport when we pick him up next week."
Mia stripped instantly, eyes blazing with excitement. "I'm tying you down, Mom. You're watching me win while Dad talks about spreadsheets."
Sophia allowed Mia to push her onto her back in the center of the bed. Mia stretched her arms above her head and tied them loosely to the headboard with Dad's own silk ties. Then Mia straddled her face and guided one thick end of the double-ender deep into her own dripping pussy. The other end jutted out obscenely. She sank down onto Sophia's waiting mouth, grinding hard while staring straight at the open doorway.
I climbed onto the bed behind Mia and drove into her ass—the plug already buzzing on max—while the dildo buried itself deeper into both of them at once. The wet, filthy sounds filled the room and spilled down the hallway.
Mia moaned loud and shameless. "Fuck— yes— stretch your stepsister while Mom eats me! Right on Dad's bed!"
Sophia's tongue worked frantically between Mia's legs, moaning into her stepdaughter's pussy as the dildo slammed in and out with every thrust. Dad's voice carried perfectly:
"…which brings us to the revenue forecast for Singapore—"
Mia rode harder, ass bouncing, the double-ender disappearing completely between her and Sophia. I pounded her ass without mercy, the bed slamming against the wall in rhythm with Dad's slides. Sophia's tied hands gripped the headboard, her heavy breasts bouncing wildly, her own pussy gushing around the toy.
"Cum in me— breed me while he's talking about bonuses!" Mia cried, her voice echoing down the hall.
Dad coughed mid-sentence. "Sorry, team—must be the connection. Continuing…"
The rivalry peaked. Mia came first—shuddering violently, squirting around the dildo, screaming my name loud enough for the entire house to hear. I exploded deep in her ass, thick ropes pumping while Sophia licked up every drop that leaked out around the toy.
Sophia followed right after, her tied arms pulling hard against the headboard as she moaned into Mia's pussy, her orgasm ripping through her.
Mia untied her stepmom with shaking hands. Both of them were leaking rivers of my cum down their thighs. They looked at each other, then at the open doorway, and grinned like the filthy queens they had become.
"Tie on the final round," Sophia panted, cum dripping from her chin. "But we both win. The whole house is ours. The training is complete."
Mia licked a thick glob of my load from Sophia's tits and kissed her deep, sharing everything.
Dad finished his presentation. His chair rolled back. He never once looked down the hall.
**The End.**

**Epilogue – Six Months Later**
The renovation was finally finished. The house looked brand new… but the real changes were the ones no one could see.
Dad was away on another two-week trip. He still had no idea.
Sophia, Mia, and I had turned the entire place into our permanent fuck palace. The bunk beds were gone—replaced by a custom king-size bed in Alex's old room that the three of us shared every night. The video vault had grown to over two hundred clips. Some were so risky we only watched them when Dad was gone for weeks at a time.
Mia's period had finally synced with Sophia's after months of breeding teases. No pregnancies… yet. But the tests stayed in the nightstand drawer, and every late period turned into another all-day marathon on the marital bed with the cameras rolling.
Sophia had taken to wearing short dresses with no panties whenever Dad was home—just like the old days—but now she'd casually "forget" a fresh creampie leaking down her thigh while she served him dinner. Mia loved making her lose the load-count contests on purpose so she could watch her stepmom squirm through family movie night.
The rivalry never ended. It just evolved.
Some nights Mia tied Sophia to the headboard and made her watch while she rode me for hours. Other nights Sophia took control and edged us both until we were begging. And every single time Dad's plane took off, the three of us fucked like the world was ending—on the kitchen island, in the backyard at sunset, on Dad's office desk, or in the master bedroom with the door wide open.
We were corrupted.
We were addicted.
We were family.
And we wouldn't have it any other way.
**Final Load Count (six months later):**
Mia: 187
Sophia: 184
Alex: still standing… barely.
See you in the next fantasy, filthy reader.
Thanks for riding the bunk beds with us. 🔥
