UK First timer

Hi beautiful people, just recently meet a very sexy girl thru a site much like this one who wants me to fuck her in front of her b/f.
We've been sending kinky text and pics to each other and have set a date for a meet. Just wondering as this is the first time both of us have done anything like this before, is there anything i need to know/remember/ or just advise you guys could give a first timer.

pls no advice saying enjoy it ( she is very sexy so i will,lol)
