The fetish s*x romp between the two lovers took place on Saturday, November 7 at the Microtel Inn and Suites in Tampa, Florida.
The victim, whose name was given as Christina Meagher of Tampa, allegedly told her shooter, Tyrone Ahmahd Fields to put a gun to her head as part of their extreme s*xual activity.
The couple, it was learnt, had only known each other for a few days when the horror occurred.
According to police report, Fields said he took the magazine out of the 9mm semi-automatic hand gun but forgot to take out the bullet already lodged in the chamber, then he pulled the trigger, killing her.
Fields has been formally charged by Police in Florida with manslaughter with a weapon, a first degree felony, which carries a maximum prison sentence of 30 years in state prison and a fine up to $10,000.
He is currently being held on a $30,000 bail bond.
