the switch back 

The process of switching from one female to the other through sexual intercourse. Whether it's oral, anal, or vaginal, the females must be on each other or close by in order to complete the switch back fast enough.

Sarah and Tina were laying on top of each other kissing, while Jim was preforming the switch back on both of them.
