So basically what you are looking for it like... she is laing back into a couch (not long ways, normal facing on a couch) and you are in front of her, facing the couch? Like missionary on a couch with the guy on top?
Thats my take when you say sitting missionary but you are standing or kneeling. got me screwed up cause when you say she is "leaning foreward" I dont know what that means.
