Help me with this one, Please!

My brother called me today and he is in the military overseas and was wondering about an old song the he used to listen to with his girlfriend at the time and is now married to her. The song is from somewhere around the mid to late 90's i believe, it was probably considered rap at the time... It goes something like this...

" How would you like it if i hit you with a 69...
can i hit it from the back, do you like it like that...

Something like that..... help me if you can... thanks

Try this....
