For a moment i wasn't sure how to proceed since it keeps says me that if i can't progress i should just go and sleep but then i figured! Seems like the first time I didn't see it but when I go to "uncle's house",put the "maid outfit" and go down to massage him it's says not that you need to proceed with other quest first...IT'S SAYS: "THE MAID OUTFID IS NOT COMPATIBLE WITH THIS QUEST" - so i just go back to change in my usual "slutty" outfit and then go back to uncle and it worked! This is how you can proceed to unlock the other quests! Just try to look more carefully to what exactly the options for the quests says!
