Sports Illustrated released its fourth of a five-part series on a plethora of NCAA violations at Oklahoma State University (OSU) over a period of about a decade with "Part 4: the Sex."

At OSU, and with other college football programs, teams will use a "hostess group" as a recruiting tool. At OSU, "Orange Pride" was a group of female students who would take recruits on dinner dates to lure them to commit to the school.

To open the article, SI details one recruit in 2003, whose identity was kept anonymous to protect the identity of the girls, who received services from Orange Pride girls. When the recruit's plane landed in Stillwater, Okla., two girls picked him up and said they would be taking him to dinner after making a stop first.

The recruit said he then had sex with the two of them.

"Rock 'n' rolling, I had the best of the best - the aces," he said.

Hostesses have been a part of college recruiting since the 1960s, when female, often attractive and friendly undergraduates would take the recruit and his family on a tour of the campus and explain various things about the school and football program. There have been numerous whispers and rumors of sexual infractions with these hostess programs, but none that had been substantiated.

Still, those suspicions helped lead the NCAA in 2004 to prohibit, sex, gambling, drugs and alcohol in recruiting.

While many schools discontinued their hostess program, OSU continued it, unchanged, and it was working. Orange Pride membership grew aggressively and former players confirmed a small amount of the hostesses were, in fact, having sex with recruits.

"There's no other way a female can convince you to come play football at a school besides [sex]," said Artrell Woods, a Cowboys wide receiver from 2006 to '08. "The idea was to get [recruits] to think that if they came [to Oklahoma State], it was going to be like that all the time, with... girls wanting to have sex with you."

Woods said he did not ever have sex with an Orange Pride hostess, but new of recruits who did. Some of the hostesses who spoke to SI, anonymously of course, said most of the girls did not engage in sexual relations with the recruits.

Chantal Drumgole (née Sanders), an Orange Pride member during the 2003-04 academic year, said there was a sub-group among the hostesses of girls who were known to cross the line sexually. None of the former players or hostesses told SI any OSU football staff member or administrator instructed Orange Pride member to sleep with a football recruit, but some football staffers said the coaches knew who some of the girls who would sleep with prospects were.

A former Orange Pride adviser and two former OSU staff members said coaches would sometimes pick which hostesses would be paired up with which recruits.

Les Miles, the OSU head football coach from 2001 to 2004, said he and his staff took the Orange Pride's role in recruiting players seriously and did not promote the use of sex as a tool.

"The volunteers' role in our program was important and I wanted to stress how seriously we took their duties and responsibilities and the manner in which we expected those students to conduct themselves if they were selected for Orange Pride." As for the role of sex in recruiting, Miles wrote, "I am not aware of this ever happening and am quite sure that no staff member was aware of recruits sleeping with this group of students or any other students."

OSU administrators accused SI of over-playing a small amount of alleged sexual encounters between Orange Pride members and recruits. The school said the revoked a scholarship offer to a top recruit after an Orange Pride member said he gave her unwanted sexual attention.

The school did confirm, however, that Orange Pride was a prominent recruiting took for Miles and for Mike Gundy, Miles' offensive coordinator who took over as current head coach in 2004.

Still to come from SI is the final of the five-part investigative piece, titled "Part 5: the Fallout," which will be released in print and online on Sept. 17 including the entire report.

Already out is "Part 1: the Money," "Part 2: the Academics" and "Part 3: the Drugs."
