The 19-year-old female student simply known as Yevgenya S was duped into stripping her clothes to win latest smart phone, iphone X, only to be handled her own phone after she has done their bidding.
Her cheaper handset was pinched from her bag and given to her as her prize instead of the promised apple phone.
The footage emerged, showing the teacher trainee covering her breasts at the night club at the venue in Troitsk, Russia.
She has however been expelled from her college after authorities saw the video online.
The trainee said she took part in the contest after watching males in the club do the same.
“We were enjoying ourselves, drinking, then the competition began,” she said.
“The host started with boys, and then it was my turn.”
Shot on a phone by an onlooker, the clip shows the competition’s host urging Yevgenya to remove her panties, offering to hug her and cover her so spectators won’t see when she does so.
Yegenya’a mother, Elena, reportedly works several jobs to fund her daughter’s education.
She said her daughter was old enough to maker her own decisions but sometimes ‘does what others tell her’.
‘She is not 15, she should think with her own head,’ she said.
