I am meeting up with a girl tomorrow for the third time. I've built a lot of comfort with her, french kissed and touched almost everywhere apart from the boobs and pussy... But I am away from home, it's a long way back to mine. Does anyone have any ideas how I can f-close her? Any good venues or good routines I can use (has anyone had sex in the cinema haha)?

Sex in cinema ? No.
Full handjob ? Yes.

You ever heard about hotels ?
Big car is sufficient, too.

Iam on a tight budget for hotels... How do I ask to go to her place? My place is about 3hours away by train.

Don't ask her, expect it.. I mean if your both on the same page (assumed) she's gunna be looking for somewhere to go too...

You "so let's get out of here!?" ,

Her "ok, where?"..

You "We're going to yours, right?" "I mean I live 3 hours away.

If you struggle to lay it out like this.. you need to build the assumption early.. Discuss stuff which can only be shown/done at hers for later on. I.E your internet is down, wanna watch a movie - her house is closer, Does she have a pool for a swim? House mates are all at your place no privacy.. blah blah blah..

If she wants it, she'll suggest it.. IF.. it is an option... remember there can always be trivial little dumb reasons why she wont feel comfortable bringing you back to hers.... so try not to get disillusioned if she doesn't go for it, this time.. Brush it off and try again later.. OR just take her to the freaken park
