Cum Sisters(2006)

Celine and sweet half-sister Antje are enthralled by each others' cunts, the textures, the smells, the tastes. Still, as soon as a few big cocks appear, their twat-fixation switches gears to a tunnel vision bent on dick consumption. The pair are slaves to sticky, white sperm and what little they can't get down their throats, they lick off with hungry tongues.
