Elena, Slavena and Ljuba are still in the basement of Desecrator, the Black Master who taught them how to properly serve.
He had decided to invite three other Black Masters to the orgy, Punisher, Spreader, and Giver.
Slavena and Ljuba are still waiting for their impregnation and more domination, and three Black men is exactly what they needed.
As for Desecrator, breeding once more Elena is clearly an opportunity he doesn't want to miss.
