E.C.M. 3 is the third installment of Zankuro's E.C.M. flash animation galleries.
This specific one contains ten sub-animations, each depicting a different pose starring the artist's character Ishtar-san.

Some sequences of those sub-animations have been converted to .gif and may be found in this pool.
The original project contains a menu bar to access the different poses. Furthermore, each of those feature a control bar allowing the user to select a number of variations such as movement speed, altered movement, ejaculation, lactation, etc. Thus not every single possible sequence might be found in this pool.
