68...and I'll let ya owe me one.

And it's only selfish depending on who's giving and who's receiving...me, I'm a giver by nature.  

Just remember that the square roof of 69 is 8 something..

ate something....

of 69 is approximately 8.30662386291807

butt not sure what halfway to 69 would be :-?

unless.. it's almost ate something.

i was ate before i was seven...

1/2 of a 69  is when the woman stops at the belly button which leaves the man at her knees ... literally and figuratively!

..."Please blow me and I'll owe you one."
