Vera told police she had gotten pregnant and had an abortion after Child Protective Services questioned her about the relationship in February, according to KTRK-TV, an ABC affiliate.
She said she initially resisted the boy’s advances until sometime last fall, when she agreed to hang out with her student.
Prosecutors say Vera and the teen had sex almost every day for nine months.
“I think she was driven by being in love with him,” Lawson testified in court, according to the Houston Chronicle.
The investigation began after the school principal received a tip about Vera in early 2016.
Back on February 8, the girl says she went to Pacana's class and sat with him near his desk where they would normally talk.
While she was sitting there, she says he began playing with the holes in his jeans on her left thigh and when she leaned over to get something out of his desk drawer he reportedly fondled her.
Her sentence was capped at 30 years after she pleaded guilty.
Vera told police that she met the boy during summer school in 2015.
She will be eligible for parole in five years, the Dallas Morning News reported.
