A woman who sent five boys naked photos and sexual videos of herself through Facebook has been jailed for two years.
Gail Wright, 44, groomed the teenagers, who were aged 14 and 15 when they met her in 2015, and had a sexual relationship with one of them.
Police said the case was "unusual" because the perpetrator was a woman.
Wright was caught when the father of one of the boys saw the photos on his son's phone. She admitted seven offences at Nottingham Crown Court.
Police said Wright, of Elmtree Close in Shireoaks, struck up a friendship with the first boy, who "felt he could talk to her about things".
However, this escalated into her sending him naked photos of herself and making sexually explicit comments.
She then sent naked photos of herself and videos containing sexual acts to all of the boys.
She also bought one of them Nike Air trainers and clothes for his 16th birthday after she had begun a sexual relationship with him.
Investigating officers found 42 images on Wright's iPad which she had sent to the boys.
She pleaded guilty to one count of sexual activity with a child, two of possessing indecent images of a child and four of causing a child to look at images of sexual activity.
Det Insp Pete Quinn from Nottinghamshire Police said: "This was an unusual case in that the perpetrator was a woman.
"But this goes to show that although the overwhelming majority of sexual exploitation cases brought to the attention of police are perpetrated by men against girls, we cannot be complacent about the fact that it can happen to anyone, anywhere."
In addition to the jail sentence, Wright must sign the sex offenders register for 10 years.
