It'd come down to basically having orgasm-based "causes of death" for each of them, likely based around their abilities, though it'd need to have ways out for each one, and the traps would need to be based around their abilities.Like, for Radiance (Rarity), likely it'd be her holding something with her magic, like a bomb or weight, that, while she's holding it in place, she gets fondled in an attempt at having her focus broken and dropping whatever she's intending on keeping held up with her power.Fili-Second (Pinkie) may have something similar only based much more around being kept in place and, once her orgasm is reached, whatever is meant to 'trigger' (some sort of trap) is activated by the Mane-iac, which Fili-Second shouldn't be able to run from in time.You get how it'd work by now, though.
