i think her desire to submit probably at least makes her try. can't imagine she's actually any good at giving head but she's submissive and timid enough to let you use her mouth even if it makes her gag. she displays all of the characteristics of a woman that prioritizes pleasing over being pleased.
Do you mean is the action of it different? or the experience?
I remember in one of her stream she said this taste like piss.Chat said jokingly and how do u know what piss taste like she reacted the usual way
