I love the idea of being not only tied up by a female but really dominated and humiliated. My ex girlfriend would tie me up but she wasn't dominant naturally so she wouldn't secure me as tightly as I'd have liked and it was an effort to get her to gag me (eventually she would cleave gag me with her panties) but she wasn't one for being rough or teasing/torturing at all. I'd have to mphhh into the gag quite loud to get her to put her hand over my mouth as well which I absolutely adore.
If I could write a step by step guide for a girl to tie me up and dominate me it would go like this:
1) hand gag me and tell me to do what you say. Make me strip naked except for a pair of your panties.
2) push me roughly onto the bed so I'm on my stomach, tie my wrists behind me with rope, then sit me up and tie my torso. Then tie my feet and knees together.
3) push me back into my stomach and blindfold me before hand gagging me again and telling me you are going to gag me to keep me quiet.
4) tie panties in my mouth as a cleave gag then tie another pair over my mouth as an OTM gag.
5) hogtie me.
6) tease me by hand gagging me over the actual gag and whisper you are going to torture me.
7) kiss my nose and lick my body. Driving me wild.

leave me to struggle while you go and watch telly or shower.
9) come back hand gag me again but ring one of my friends using my mobile and tell them ou are ringing on behalf of me as I'm a little tied up at the minute.
10) more teasing by tickling my bare feet.
11) some spanking or whipping but nothing too extreme.
12) slowly rub my penis but don't let me come until you've teased me more by again licking me all over and my nose.
13) finally let me come but hold your hand over my gagged mouth while you do.
