A young mother was arrested after confessing to having sex with a minor and supplying him with drugs.

Police arrested Brittany Sonnier, 23, of Holly Hill, Florida after the 15-year-old boy, who lived next door, told his parents about the relationship.

The boy told them after becoming concerned he may have contracted a venereal disease when he learned Sonnier had been accused of having 'vaginal and oral sex with two canines' in 2012.

According to a 2012 police report obtained by The Huffington Post, a former boyfriend of Sonnier revealed that she told him she had engaged in sexual activity with dogs, and that she had fantasies of incest.

She said she had been intimate with the animals since she was 13-years-old.
