One thing that I've been thinking about is how you get rid of the girl when you wake up in the morning? Do you offer her breakfast or give her a ride home? Let's assume it's a ONS.
Well my friend the options here are plenty. Let's assume that you have successfully placed the lady in your own home, more precisely in your own bed. The night comes to an end and you both fall asleep at 3-5 in the morning. Now you've gotta be smart, if mom comes home from her nightshift at 8 you're best off pulling a "day-before" lie but if you live alone in your golden bachelor pad it's more tactical to be a little sporadic.
A "day-before" lie is something that makes sure an end will come the next day. This means that you pliantly add a few words on the way home in the cab or when you both lay naked in your bed while she is moaning to your tongue-esque skills around her neck area. "I've gotta get up early and work out in the morning", "I promised to walk my neighbours little dalmatin", "gotta buy newly baked bread for the sunday coffee" or the classic "I've gotta get up in time for the booksale." Then they will already be prepared to take their stuff and gtfo of your life as a proud single for good as soon as the sun is up.
But if you don't want to bother and make the effort of planning that far ahead there are plenty of solutions to make her scram. One that I use quite a bit, that works best on fridays is to "accidentally" drop her keys through the window. That will trigger her to free willingly dissappear in the form of a sprint. If you don't like that one you can "offer her breakfast" to seem like a nice person, just remember that before she answers you add "though I've only got some old christmas crisp bread and homemade room temperatured liver paté." It's a guarantee that she will get out without even visiting the bathroom to fix her fucked up hair. If you want to seem like an oriental god you should do the "other-room" trick.
Now on the "other-room" trick you make sure to wake up, or atleast get out of the bed first and walk out of the room. Close the door behind you. The girl will now be unsure on what the hell is going on, at first she will assume you've just gone to the bathroom. About 20 minutes later she will come out of the room, all dressed and puzzled. (This is where the trick get's a little diverse - if she remembers your name she will shout for you across the pad, however it is most likely that she doesn't and then she'll walk right towards the front door.) If she remembers your name you will have a tactical hideout behind the sofa with supplies, water and salami sandwiches. You will hide there until you know she's gone.
An important thing to add to the notebook is that you never ever give her breakfast. No ONS is worthy of that.
Good luck.
