A 25-year-old Indiana mother pleaded guilty this week to selling her baby eight different times so a man could have sex with the infant.

Natasha Hillard faces a minimum of 30 years in prison for renting out her baby, who was between 4 and 16 months old at the time, for sex to 40-year-old Christopher M. Bour.

Hillard, who has two daughters, was reportedly in the room for seven of the eight sexual encounters. The eighth time she allowed the man to sexually abuse the infant without her supervision.

Federal officers were tipped off by a masseuse, who said she saw child pornography in Bour’s Gary home. He later asked the masseuse to take picture of him having sex with the infant, which he said he had Hillard’s permission to do.

"I was just seeing if u would hold the camera," he texted the woman, according to the indictment.

He described in graphic detail the sexual perversions he had planned and wrote the woman, “It’s the best sex I ever had.”

Hillard met Bour through a dating service in 2011, the New York Daily News reported. Federal authorities say she also let Bour take sexual photographs of her 3-year-old daughter.

Bour is expected to plead guilty at a federal court appearance on Thursday.
