[noncon story advice] cocaine effects on sex drive

[swimsuitkink]

So, about the typical cumrag gangbang story.

A woman harbors secret fantasies of getting taken by many men. One day it happens, her assailants feed her drugs or magic aphrodisiac then gangbang her until she likes it.

How realistic is that?

I'm writing a story where her captors force her to snort coke off their dicks. What are the effects in reality?
