PORT ST. LUCIE, Fla. -- A Florida woman is accused of paying a child hundreds of dollars for multiple sexual encounters, police said.

Rebecca McGraw, 38, of Port St. Lucie, who was arrested Thursday, is facing five counts of unlawful sexual activity with a minor by an adult, Port St. Lucie police said. They said she admitted to at least five sexual acts with the victim.

However, the 15-year-old boy told police that the two had up to 16 sexual encounters, TCPalm.com reported.

The boy said that, after meeting McGraw around spring 2016, she invited him into her home, where "he would hang out there frequently and smoke marijuana and drink alcohol," according to police records.

McGraw remained in the St. Lucie County Jail on Saturday with her bail set at $125,000.

The age of sexual consent in Florida is 18. No one under the age of 16 can give consent under any circumstances, according to Florida statutes.

Authorities arrested McGraw, who has two daughters, after detectives followed up on prior allegations of child abuse and sexual molestation of a child by an adult.

McGraw was an assistant manager at the Sail Pointe Apartments, off Federal Highway north of Port St. Lucie Boulevard. There she engaged in a sexual relationship with the victim, who lives in the complex, police said.

Authorities said she paid the boy up to $300 for each of the sexual encounters. She would let the child use her debit and credit cards and operate her vehicle without her being present in it, police said.

Earlier this month, police arrested Port St. Lucie High School chemistry teacher Tiffany Geliga, who is accused of an inappropriate sexual contact with a 17-year-old male.
