M. M. squats (#1).  She pushes the back of her tights down her buttocks.  I do this picture with a Digest  cover in mind: nipples hidden, very seductive look, hand play (#2).  But I have her show her left nipple anyway (#3). 
   M. M. stands up, gets her riding crop, turns to the back and pushes her pants (#4) down her buttocks (#5), and turns to display her long sex lips (#6).
