Jun 14 Word of the Day
Referring to women who are sexually or romantically attracted to other women. Applies to both lesbians and bisexual women, as it is only the same-sex attraction that matters, not any other attractions the women may have.

Originates from the Greek poet Sappho, a bisexual woman from the Isle of Lesbos, from which we get the term lesbian.
The sapphic women greatly enjoyed each others company.

The most amazing sexual position ever! One couldn't even compare it to 69 or even the lazy dog!! It's simple enough, just get your unconscious victim... er willing partner to lie on the their stomach and place your "candy" on top of their "jiggle mountain". Relax and enjoy
Caren: Ughh... Mike left semen crusties all over my left cheek from 73ing last night

Aaron: I have some from Mike too... at least it was fun

Caren: That's for true : way better than 69ing

Aaron: Or even the lazy dog!
