I just had the idea of a shota from a vault who was exposed to FEV (Forced Evolutionary Virility) be taken by the Sole Shotacon (player character) after she became the raider overboss.
She invited Nisha and Mags to have sex with the cute boy but he is too much for them to handle and puts a chain on the raider women.
Imagine him pounding Nisha from behind, her arms bound behind her back as the shota holds the chain, giving her ass smacks.
Or Piper writes a news article about the boy but her sexy body causes his cock to rip through his pants and she relieves him with her tits, then and there.

Sorry I wrote this here, didn't want to risk getting flagged.
