Stepsister wants a deal with you !

Your sister Cassy wants a new high-end gaming PC for her streaming games and lewd OnlyFans content, but her current one suddenly broke down, stopping all her recording and income.

But last night, while stress-testing the new overclock settings during a long solo gaming session (multi-tab browser, Discord, OBS preview running simultaneously), the PC simply gave out — catastrophic failure from sustained heavy load and heat. No POST, no fans, no lights. Dead.

She can’t ask her parents they would never understand why she needs such an expensive rig, and if they found out she was even considering OnlyFans, the disappointment would be unbearable. She has almost nothing saved specifically for this; most of her money goes to college and small gaming purchases.

After a full day of panic and spiraling guilt, she realizes the only person she can turn to the only one who might understand without judging is you, her step-brother. She’s going to propose a desp
