Professors are sometimes bumbling fools.

 MPCFS  Multiple position
 MHCFS  Any hole is OK or Multiple Hole Covered Full Sex

I have to stop checking the websites to see who is new and visiting our fair city.  I noticed a new girl, Sadie, visiting with PrimeDC, and I was digging what I saw.  Sadie has a spectacular body, is brand new to the biz and is eager to please.  An incredible kisser - it turned her on as it did me.  Highly RECOMMENDED.

Location:  Dupont Circle, incall
Donation:  $$$
Pix:  accurate but she is more lithe in person - great smile, breasts, overall athletic shape.
Piercings/tats:  pierced navel/2 tattoos (1 in small arabic characters runs down her spine from her neck to her shoulder blades; 1 is lower back).  Neither tattoo was distracting at all.
Services:  DFK, DFK, DFK [a lovely kisser], DATY, DIGITS (in V), HJ, BBBJDT (CIM - spit), MSOG, MPCFS
Looks:  9 - very sweet face, outstanding body but her breasts are epic
Performance:  8 - she will improve and get better.  The next guys will get the benefit from the "new adopters".  She had 2 real O's, no faking here.
Recommended:  Absolutely YES!!!!

Sadie was amenable to suggestions and eager to improve the pleasure quotient.  She was great (I was her first foray into the biz) as it was, I did try to school her up and she will improve.  I will see her when she returns.  Review to follow.b  Cheers!

I saw it in a recent post here. I guess it means a provider, but I don't recall seeing it before.
