Mie Skard, russ president for Oslo and Akershus county, said that girls from seven other buses have reportedly agreed to take part in a porn film in order to help pay for their mobile party bus.

The 26 girls from two Oslo schools had agreed to be extras in a porn film that would feature scenes shot in their bus, and would also talk on screen about their sex habits and fantasies.

Newspaper VG reported that two of the girls also agreed to take part in sex scenes with porn star Thomas Rocco Hansen, but this claim had not been confirmed.

Skard was relieved when the Oslo girls reconsidered but is now exasperated to learn that Rocco Hansen was claiming he had contracts with girls from seven other buses.

"All of the russ I have spoken with are shocked - luckily we have not gone so far as to think this is OK," Skard said.

Skard admitted that the traditional competition to customize the best russ vehicle had become an incredibly expensive habit, and that it was now not unusual for these buses, equipped with enormous sound systems and rebuilt interiors to cost each participant NOK 25,000 (USD 3,580).

"We can't stop someone from taking part in a porn film, but I hope these other girls that Rocco talks about think this through one more time," Skard said.
