Since there is the implication that in a state of inebriation Peridot drank Lapis, there is also the possibility that, while tanked on beers, Lapis admitted that she had always wanted know what it was like to have some one "drink" her like water and Peridot admitted to wanting to know what it was like to "drink" some one and that it was all a drunken sex-type thing.
