I think she should handcuff and blindfold you. She should require you to be nude or wearing a thong/skirt/something embarrassing at all times. She should put clothes pins on your nipples and sack. You should lie on the bed while she sits on your face and makes your lick her pussy and/or asshole (assuming she cleans up before). Lastly, she should suck you to orgasm (you will be blindfolded) while fingering your asshole, then with the cum in her mouth, she should open mouth kiss you. After that, she can take a shower and you can bathe her.
