Mistie Rebecca Atkinson, 32, was sentenced to four years and eight months behind bars in Napa County Superior Court, California on Wednesday.
It came after she was found in a Ukiah, California motel room with the 16-year-old boy, who had recorded his mother giving him oral sex on his phone.
Sick: Mistie Atkinson, 32, (pictured left in her police mug shot and

her son, 16 - but she claims it was a case of 'genetic attraction'
Authorities also recovered nude photos Atkinson had sent him after tracking him down through Facebook. She had not seen him for 15 years.
But in a letter to the court, Atkinson, claimed she did not consider it incest, the Napa Valley Registerreported.
'I don't feel like I should have the charge of incest because there is something called genetic attraction that is a very powerful [phenomenon] that happens to 50 [per cent] of people becoming reunited with a long-lost relative,' she wrote.
Little research has been carried out on genetic sexual attraction. But some psychologists say family members who are separated for a long time could become sexually attracted to each other when they meet as adults.
Guilty: Atkinson's son had a video on his phone of his mother
giving him oral sex, police said
Caught: They were found together in a motel room after relatives
learned of their explicit Facebook messages
Atkinson could be out in as little as two years and four months for good behaviour.
She reportedly had no contact with her son until last year when she began sending him inappropriate messages on the social networking site.
The boy was living with his father at the time and was aware Atkinson was his mother. She did not have custody rights to her him.
'It appears she hadn't had any contact with the son for 15 years' a source told the New York Daily News.
'She contacted him late last year via Facebook and was sending him messages inappropriately.'
The sexual contact began after police responded to domestic violence reports between Atkinson and her live-in boyfriend in Nice, California.
The relationship came to light when the boy's relatives reported the inappropriate Facebook messages between him and Atkinson.
Atkinson and the teen were found in a motel room on March 2.
