A 42-year-old teacher has been arrested after admitting to giving one of her middle school students a "full contact lap dance" in front of her entire class.

Felicia Smith of Houston, Texas, is being charged with an improper relationship with a student after she reportedly rubbed her hands all over the boy's body and then dropped to her knees and put her head between his legs.

The boy says he slapped Smith's ass several times during the incident, and a probable cause affidavit notes the teacher's moves caused him to "have an erected penis."

Smith ended the nearly four-minute-long dance by saying, "I love you, baby. Happy birthday."

The victim is 15.

Investigators are reviewing a video of the lap dance. Smith told them that her other students convinced her to grind on the boy as a joke.

Smith is free on $30,000 bond, and is due back in court May 22.
