Angry swallow

When a girl is adamant that she doesn't swallow but you blow your load in her mouth, pinch her nose and seal her mouth til it's gone anyway.
Not only will she be pretty pissed off at what has just slipped down her throat, her arms will undoubtedly be flapping about like an angry bird fighting its way out of a cat's jaws!

A vet described an angry swallow as the sexual equivalent of getting cats and dogs to take tablets, only without putting your dick in their mouth first.

The more of a princess she is the more potential for an angry swallow.
