Alvergonzalo invites us to witness a sacred profanity, a baptism in sin. His lover's "nalgotas," like twin holy water fonts, await his devout adoration. With reverence, he anoints her ass with his tongue, tracing the curve of her cheeks, diving into the valley between. Her moans, her "agua santa" dripping down her thighs, are the confessions of their shared transgression. This is not just worship; it's a communion of flesh, a sacrilege that feels sanctified.
