What do the sexual terms 114 & 89 mean?
Must Be 18:
The only reference to a sex position 114 we could find was from an Australian site (see source link to site below). They show it as the man standing on the edge of, presumably, a bed with his lover standing on the floor in front of him performing oral sex.
For 89 we found a couple of possibilities:
One suggests that it's performed by placing the man's penis between his lover's breasts; the 8 represents each breast, and the leg of the 9 represents the penis.
The other definition describes it as sex with an overweight person, the 8 representing that person.
It's most likely a play on 69, in which a couple positions themselves head-to-toe in order to simultaneously perform oral sex on each other.
