Everytime when Julia-Eva plays with her slave comes the question Fun or Pain?
For her it seems to be, that inflcting some pain makes fun... for her!
But maybe not for him. Who cares?
She starts sitting on him, squeezing his head between her strong legs.
He tryes to resist and throw her off, but she's to strong and heavy, no chance for him.
A little pain? How is about rib-crackung kneedrops, her weight makes a good job.
Or under her fleshy ass is no air-supply... struggle for live = fun for her... for him, who cares ;-)
Tickling while heavy chestsitting, headscissors, taking his air with fleshy belly.... and so on.
