sure I'd let the dude f*** my girl in front of me; cause he has to know that once he's done in her I'm going up inside HIM and what he did to her I plan to do the same to him. [he might think twice how hard he f***s her!]
so true; you can watch, you can join in, you can let her be the center of attention or YOU can be in the middle of the sandwich; combinations are plentiful!
