The state has called for a lengthy prison sentences to be imposed on former powerboating champion Lionel Ball and his co-accused Nokuzola Ntonga.
They will be sentenced tomorrow.
Counsel for Ball reportedly conceded that direct imprisonment was appropriate, while Ntonga's legal counsel called for a lesser sentence than life imprisonment.
Ball was found guilty of the charges in December of rape and sexual exploitation, while Ntonga, was convicted of conspiracy and aiding and abetting Ball to commit a sexual offence.
The court heard that Ntonga had procured under-age girls for Ball.
