If the Princeton Review were to add a category for porn schools, then Indiana University might make a claim for the top spot.

Shane Enterprises from Van Nuys, Calif., taped 20 to 30 students engaging in sexual acts in an Indiana dormitory. Shane Enterprises is the creator of such flicks as “Taped College Confessions” and “Drive In: Naughty Little Nymphos.”

In September, the same company filmed “Shane’s World 29: Frat Row Scavenger Hunt 3” on the Arizona State campus. The production took place primarily on fraternity property, although one scene did take place in front of a university dormitory. The performance also included the ASU student government vice president.

Indiana University is determining if the individuals broke any school policy. If they did, said university officials, they will go ahead and discipline the students.

The Indiana University Code of Student Rights, Responsibilities and Conduct prohibits “lewd, indecent, or obscene conduct,” which university officials are examining among other rules to see if the students violated this code.

IU may also discipline students for activities off-campus if the misconduct “undermines the security of the university or the integrity of the educational process.”

The film was shot at Teter Quadrangle, an IU dormitory, and showed actresses performing oral sex on students in the dormitory hallway. Shane Enterprises said they verified that all students were at least 18 and in addition had each sign model release forms.

Adult film actress Calli Cox told the Indiana Daily Student that she wanted to “party with students from the No. 1 party school.”

An investigation into the alleged filming started after Teter residence manager Cedric Harris was summoned to the dormitory. The film crew was then kicked out.

The film crew was in the dormitory for nearly 30 minutes while students reported seeing sexual activity in private rooms and the dormitory showers.

“I know that the girls were doing, like, lesbian activities between each other,” IU student Aamir Bharmal told IndyChannel. “The guy and the girl did something in one of the kids’ rooms. The students were all just watching.”

Like the ASU shooting, it appears no direct sexual intercourse was performed in this video, according to witnesses.

An investigation by the Indiana University Police was recently completed, but no details have been released to the public. The investigation was started at the order of the university Oct. 23.

A spokesman for Shane Enterprises said the company would be willing to talk more after the video is released.

“We’re not going to comment on the video until after it is released, and that is two weeks from now,” the spokesman said.

The film, “Campus Invasion,” is slated for a December release.
