A 54-year-old University of Colorado Denver employee in now on administrative leave after the University learned she allegedly ran a phone sex business during her work hours, CBS Denver reported.

Resa Cooper-Morning, a CU employee since 1992, is under investigation by school authorities for operating a phone sex line through her website, "msresa.com." For $1.49 a minute, customers can call Cooper-Morning for "phone sex that will rock every part of your body!" the website said.

According to the website, Cooper-Morning is available to chat Monday through Friday from 7:30 a.m. until late, hours that overlap with her 7 a.m. to 3 p.m. CU work hours, CBS Denver reported.

"The University of Colorado Denver takes this allegation very seriously," Leanna Clark, CU Denver Vice Chancellor of Communications, told CBS Denver.

CU learned about Cooper-Morning's website business from CBS Denver, and has now "initiated a thorough internal investigation."

Cooper-Morning, who is still collecting her $68,000 salary while on leave, is the cultural diversity coordinator with the school's Ethnic Studies department. CBS Denver collected records indicating that in 2003, she established a website that included nude, suggestive photos of Cooper-Morning.

The website gives visitors the option to buy memberships with access to several soft-core videos of Cooper-Morning. Video titles include "Erotica in Pink," and "Vanilla Cocoa Butter Oil," CBS Denver reported.

According to Clark, "under Colorado state statute, no employer has the right to restrict an employee's legal, off-work activities," Clark told CBS Denver. The problem is Cooper-Morning may have conducted her phone sex business while being paid with taxpayers' money.

"She does it while she is working at CU Denver," Blair Cooper, the cultural diversity coordinator's daughter in law, told CBS Denver. "I've been in her office and she's said, 'Oh let me be right back I have a phone call.' She takes them very discreetly, shuts her door, take phone sex calls on CU of Denver's pay."

CU told CBS Denver its investigation could take up to four weeks. Cooper-Morning's website is now shut down.
