Not bad, I like it :)
Here are some little things you probably want to fix ;)
1) general:"YOUR" cock is making *ME* so hot."
-- One quotation mark too much and you miss the *
2) general:"Can *ME* use her brests *ME*? She loves the way your cock feels between them."
-- breasts
3) general:"Can *ME* use her brests *ME*? She loves the way your cock feels between them."
-- shouldn't it be *YOU* ?
4) vigorous:"keep fucking *MY* throat *YOU*!"
-- Keep ?
5) wake:"*ME* is sorry she passed out *YOU*,she promises it won't happen again."
-- You missed one empty space out
6) cum_on_face:"Can *ME* taste in next time *YOU*?"
-- "... taste it ..." ?
7) cum_in_throat:"More, yes?
-- You missed the last quotation mark
8 ) cum_in_throat:"more... more cum *YOU*."
-- More ?
9) finish1:"Once isn't enoughis it *YOU*?
-- enough is
10) finish1:"Once isn't enoughis it *YOU*?
-- Again the last quotation mark ;)
I think this is a very solid first dialogue and a very good start (if you consider to continue) :D
Keep it up!
