What about femboy preds? Maybe ones who can change their dicks' size, from hungry meat obelisks to quiet sissy packages, shrinking down any unfortunate victim and muffling their pleas (or moans) even more.

Imagine having a pair of twin femboy servants, identical in appearance and behavior except for their dietary preferences - and by extension, they qualities of their cum. One prefers churning big men into cum thicker than glue, so virile you can almost see each sperm; the other instead wants curvy women, brewing a silky nectar that dissolves quietly and quickly.
Imagine them working for you, fonding and bringing you cute femboys that fit your tastes. Sometimes they make their own, feminizing men or masculinizing women as needed with "injections" of their milky medicines.
And yes, both of them keep a diary where they gush over how much they want your cock to gobble them up. And they bicker over who gets to be second and listen to the other gurgling away into nothingness inside your cum factories.
