CAPTAIN'S RELENTLESS ORDERS: MY STEPSISTER BREAKS BENEATH STEPBROTHER'S COMMAND by Cassandra Mile

In the sun-drenched suburbs of Los Angeles, twenty-two-year-old Alex Rivera has spent years pretending he doesn’t notice his stepsister Suzy Santos—petite, teal-streaked, and dangerously addictive in every skimpy cosplay she wears for her growing online audience. Suzy plays the untouchable “Captain Sugyaa,” commanding her fans with haughty orders and provocative outfits… until the day their parents leave for a two-week cruise and she’s caught on all fours in the backyard, ass high, a remote-controlled toy buried deep inside her, trembling on the edge of ruin.

Alex doesn’t walk away.

He cranks the dial to maximum.

What follows is forty-eight hours of stolen, sweat-soaked depravity: brutal fucks against sun-baked patio tiles, edged torment over breakfast, risky thrusts in the garage with the door cracked open, slow, possessive claiming under scalding shower spray, and the ultimate desecration—him buried inside her on her premium-members-only stream while thousands watch, none knowing the broken moans they hear are real.

When their parents return, the game doesn’t end.

It goes underground.

Quick, silent quickies in the garage. Desperate handjobs under the dinner table. Stolen hallway kisses that taste like risk and forever. Every stolen moment laced with the constant fear of discovery—and the even greater fear of what happens if they’re forced to stop.

Suzy’s captain persona was always a performance.

Now the only orders she obeys are whispered in the dark by the one man who owns her completely.
