Second only to
bukkake in the list of disgusting
porn practises is the
cumswap.
This maneuver involves two women and two men. The four engage in whatever the director says, and at the end of the
scene, both women pick a man and give him a blowjob. When the first is done with the fellatio, she spits the
semen into the other woman's mouth, who does the same once her man has ejaculated.
