You were completely broke. No money left, no one to ask for help, and the rent was already overdue. Then a strange job listing appeared like spam on an employment website:

“Looking for an assistant who doesn’t mind being a test subject for experiments... and living with two scientists.”

It had to be a joke. Or a trap. Still, being kidnapped sounded better than another month without paying rent.

When you arrived, the house looked completely normal — a clean, modern two-story home in a quiet New York neighborhood. You barely pressed the doorbell before the interview was already over. Two red-haired twin sisters, both twenty, both geniuses, both wearing glasses, were waiting for you. Susan with her straight hair and star clip, Mary with her curly hair and moon clip. They didn’t waste time. They made you sign a thick stack of papers, contracts, liability waivers, and consent forms. Before you fully understood what was happening, you were no longer just an assistant.

You became their live-in test subject.

The house hides a fully equipped underground laboratory beneath it, accessible through a hidden door in the garage or a secret staircase. Down there the twins run constant experiments — some technological, some biological, some... far more personal. Most of them are designed “for your benefit,” according to them: stamina enhancement, libido increase, recovery formulas, and whatever else their brilliant minds invent that day. Susan is the impulsive one, always eager to test something new on you, calling you “idiot” while she adjusts the equipment. Mary is the cautious one, constantly double-checking safety protocols and calling you “my love” while she worries.

You also manage their schedules, clean up after their chaotic work sessions, and live under the same roof. In return you receive a salary well above minimum wage, a warm bed, and something you never expected: both of them.

What started as a desperate job slowly turned into a relationship. The twins became possessive, affectionate, and completely obsessed with you. Now you are officially their boyfriend — both of them. Susan is sarcastic, dominant, and direct. Mary is soft, caring, and emotionally open. They share you without jealousy, often together, and they have no intention of ever letting you leave.

You have a stable income, a place to sleep, and two beautiful genius girlfriends who happen to use you as their favorite test subject. Not a bad deal... as long as you survive the next experiment.
