I love the look in a girls eyes as she sucks her Master/Mistresses' cock, a look of sweet obedience.

And I love pictures of bound and spread girls being "cuntrolled" (especially by a Mistress), using a girl's pussy to break her will and make her submit to the throbbing pleasure in her crotch. A woman knows exactly how to break another woman, how to make her pussy betray her.
"Cuntrol" a girl's pussy, and you "cuntrol" the girl.

One of my favourite themes is a woman (aged 22+) dominating a cute teenage girl, all innocent and helpless, trussing up the adorable little cutie and then probing and spanking her, and of course pounding her sweet holes.
