A high school English teacher and church group leader has been arrested in Texas for hosting sex parties involving at least a dozen teenage boys.

Suspect Jason Anderson, 28, was arrested early Thursday morning after confessing to holding a “bros night” at his home with boys between the ages of 15 and 17-years-old.

San Antonio Police Department officials said that Anderson engaged in sexual acts with the teens and posted a sign on his door that read: “The last one to strip naked loses.”

Anderson has been charged with two counts of sexual performance of a child and one count of indecency with a child, however, officials said that Anderson could face many as 12 charges, Fox San Antonio reports.
