A teenage boy has won a competition to live with a porn star for a month, much to the chagrin of his mother.

Ruslan Schedrin, 16, won a prize to spend a month in a hotel with an X-rated movie actress when he was the 100,000th visitor to a new website selling virtual arms for video games.

The Russian child actor will be spending a month with adult actress Ekaterina Makarova, who is thought to be in her mid-twenties, and she has not ruled out having sex with him, the Mirror reports.

Schedrin is excited to be able to spend time with Makarove, who he described as having "good sizes".

While he is excited, his mother and sister are furious – insisting the prize is inappropriate for a 16-year-old and claiming it would be a huge distraction from his education.

At first Schedrin did not believe the competition was real, but when he found out it was legitimate he reacted with shock and disbelief, he told the Mirror.

"I called my friends and they did not believe it either. They said, 'what are you talking about?' Now they are happy for me too. Some of them are envious’."

He said although his mother is not happy with the outcome of the competition, he will try to smooth things out.

Schedrin's mother, Vera Schedrina, said he should be focusing on his upcoming exams and does not have time to spend a month with a porn star.

"Such a prize - how could they get such an idea for a 16-year-old boy? I am shocked. I have not seen the girl, but my son must study," she said.

Schedrin does have the choice of handing the prize to his "official representative", who is his father, but his mother is not very happy about that option either.

Makarova agreed months ago to be the price for the 100,000th visitor and believed 16 is a "good age to be independent", she said.

The adult actress is set to discuss where the two should stay, but would hope "to go on holiday somewhere abroad".

She does acknowledge his exams will factor into the arrangement and that his mother will play a part in where they can stay.
