When a man teabags a warm glass of milk while two women blow bubbles into the milk through straws.

When a male or something with nuts submerges their testicles into a cup of warm water while their partner blows profusely through a straw that has been inserted into the cup creating a jacuzzi affect. For added pleasure the penis is usually wildly jerked with the blowers free hand until ejaculation.
