Ok heres a few ideas off the top of my head. Pull the bow real hard. Take a bite out of her. Do smth with the bell i know theres smth there. You like hypnotism and there's a swirl on her... hmghgm. More overstimulation ? Tho youve already done that i guess. Lick her♡♡ that ones silly. Maybe get her in a more dominant role to switch it up i dunno ! This is alot of stuff sorry abt that
