I'm certain that when this guy was picturing having a threesome, this isn't how he saw it going down.

Last week, 31-year-old Steven Norton and another man in Hanahan, South Carolina were having a threesome with 26-year-old Cameo Louise Luchka. The latter was high on meth and heroin and was starting to pass out.

At one point, Steven tried to end it and asked her to leave. Apparently that upset her, because Cameo was so mad that she tried to bite his junk off.

The police showed up and Cameo reportedly "barked, growled, and hissed" at the officers. The wound up having to use a taser on her so that she could be taken to a hospital. Steven was taken to a different hospital to get treatment.

So far, the cops haven't arrested Cameo, but she could be facing aggravated assault charges.
