trim and fit in Sioux Falls or Sioux City or sw Minnesota area

Not to sound overly picky, but I prefer to play with a woman who is slender, fit and firm. It's been a parade of overweight ladies through this part of the world lately. They're probably nice, and maybe even quite accommodating, but flabby, obese or out-of-shape providers aren't consistent with my fantasy. Anymore, BBW is mostly code for fat, so I skip meeting women who advertise as being in that category. Can anyone point me to someone who is fit and trim? Perhaps there's someone who is under-the-radar. Please pm me.
