I honestly don't know why I like Batbreeder so much, I think it might be because she has the most expressive face and her couch scene is so well animated... She is just generally well balanced IMO and the fact you can actually Dom her is a HUGE "plus" that just catapults her even further ahead of the other girls... God I crave more Domable creatures to play with in my dungeon.
I'm right there with you in regard to MILF's... they don't get enough love, too many games use models that look barely older than an older sister to their children, so getting "real women" is like finding gold. (I'm not a purist BTW, I like the full spectrum of women, from Mature to Barely legal, from Plump to Slender, from Towering Giant to Petite Minature).
There are so many layers to the word "attractive" I don't think it can be applied unversally, Rosy has a innocence that surpasses all the other characters IMO, soooo ripe for corruption

.
Rosy is in my opinion the one who has least matched her potential so far (relative to my tastes)... when she was first introduced she was top of my list of most craved for characters... but so far I hate the junk hanging off her tits in the milking scenes and that red bow ruins the Bedroom scenes for me (I don't have the words to express much I hate it... I know it isn't rational... I just hate it... One of my ancesters might have been a Bull

).
I don't expect Tinkerer to bow to my tastes but it feels like all it would take to restore my love for her would be a decent "bent over the counter" scene and get rid of that block on Baking (where she says "I don't feel like baking... can't we do it in bed instead"

) ... and maybe a nicer BJ scene, maybe even basing it on the BJ that is already there (but this is very much a "would like" rather than a "need")
