My former lover used to do this with me...fortunately, she used Vaseline to coat her fingers. Most pleasurable!! The sensation that she was forcing the cumm out of my prostate is an unforgettable sensation. Bless her heart, she always swallowed everything she squeezed out of me
beware..... my girlfriend in high school did this to me and it was amazing. but pretty soon she was putting her dildo in me, and within a year we were both sucking her step dads cock.
