Ian suggested smack my ***** up, i'd forgotten about that one!
here's another that's inappropriate but mostly cos you'd have all your family around...... dunno who wrote it or anything but there was an RnB type song out a few years ago that went 'let me lick you up and down, until you say stop'..... and carried on in that vien! Imagine dancing to that infront of your Nan
The song you are talking about is Ludacris - Fantasy
Also you could have "Move ***** - Ludacris" or even "London Underground" lolz
Edit: Or "Freak Me Baby"
no its not ludacris,similar but not it, it is i forgotten the name of the group- the 4 guys with dane bowers in it 'let me lick you up and down, until you say stop,let me play with your body baby make you real hot, cos tonight baby i wanna get freaky with you'
is it really sad that i remember that?! LOL
ooh...i remember! its by Another level, freak me
