Although the throat stabbing in Milk My Cock is fairly rigorous at times, the POV action goes stale long before the vid ends. This is due in large part to the same setting and predictable moves of the [uncredited] guy running this show - who looks quite a bit like Julian St. Jox (but has none of his charm or cockslinging skills).
The girls run the gamut from all-natural to over-enhanced. Clearly, each knows their way around sword swallowing and cum gargling. If this action alone is enough to rock the boat of your customers, it's worth stocking.
