Public Display of Affliction

This Pure Taboo exercise seems inspired by a "people in glass houses" gimmick. It stars Sheena Ryder as a bisexual woman who's just had a violent fight (off-screen) with her lover Lily Lane, and flees to their neighbor's house inhabited by nerdy Ricky Spanish.

His set of wall-to-ceiling plate glass windows (no curtains of course) dictate the rest of the scene. She pleads with him for refuge and Lily shows up outside still angry but wanting to make up. Sheena decides on the spot to seduce Ricky and soon we're watching a half hour of them humping away on his living room couch while poor Lily watches outside (she's suddenly the "cuckold" equivalent).

That's the whole scene, utterly pointless. I suppose the "taboo" element is that we watch a character being humiliated.
