A number immediately before 70, and immediately after 68.

Such an innocent number! Why do people think it is dirty?

An overrated number... Often referred to sex, and memes, 69 is very nice.

a really overrated number that boys obsess over. this should stop

The number between 68 and 70, you fucking perverts.

Amazing sex position were man gets a mouthful of a womens pussy while the woman is eating up his dick at the same time.
