Sheen's two new girlfriends say they 'do whatever Charlie wants us to do' when they go to bed together in his Beverly Hills mansion.
'We do whatever Charlie wants us to do. This is the type of lifestyle I have always wanted, and I am just thrilled with it,' Rachel Oberlin told the New York Post.
Natalie Kenly added: 'Our bed is big enough for all three of us, and we take turns sleeping in the middle.
'If someone's really tired, there's always a place for them to sleep in peace.'
When Sheen, 45, was asked about the trio's sex-life he told the newspaper: 'Dude, is anything sacred? No comment.'
The girls told the Post they use the American football term 'the wedge' to describe their relationship, and revealed that they would let Sheen go outside the group if he desired it.
'All three of us are in a relationship, and if Charlie ever wants to go outside 'the wedge' and act out on his sexual desires, that's fine with Natty and me. We're laid-back people,' said 22-year-old ex-porn star Oberlin.
