I am sure Monika had her own thread a while ago but cannot find, I am sure she did hardcore as well. All I can find is this set with Simona

With ATK-Hairy she did only 4 lesbian sets (Sept/Oct.2008) by J.Ant.  (model code mon098JAT)

She looks alot like Mannella but not sure if it's the same girl. Worth a look?
