 " Under Your Spell " received attention from Buffy studies writers because it presents a frank and unflinching expression of lesbian romance . Buffy the Vampire Slayer was the first show in U.S. television history to portray a long @-@ term lesbian relationship among the core cast of characters . Previous televised depictions of lesbian relations were primarily limited to single " coming out " or " lesbian kiss " episodes , showing lesbian @-@ identified characters as affectionate but not erotic . Tara and Willow demonstrate throughout the series , and specifically in " Once More , with Feeling " , that they are " intensely sexual " , according to Buffy essayist Justine Larbalestier . Near the end of Tara 's song , she sings , " Lost in ecstasy / Spread beneath my Willow tree / You make me / Com — <unk> " , as Tara levitates off the bed while Willow tacitly performs cunnilingus on her . Lorna Jowett called the song " the most erotic scene " of the series . Whedon admitted on the DVD commentary for the episode that the song is " pornography " and " probably the dirtiest lyric I 've ever written , but also very , very beautiful " .
