"Extra Stark" is a good compilation series of DBM. Two hours, very strong material, budget price. A new series is "Spielzeit 4 Stunden". There is obviously a bit of filler (say 10 %), but overall it is quite good. I think the material is strong enough. Here an indication of the contents of volume nr. 6.

* Two women on a couch. Third woman fists the two of them simultaneously in the pussy (PF). They break up. One woman PF's (and later AF's) the second who all the time AF's the third. [15 minutes]
* First a girl PF's a woman. Then other woman takes over and AF's the woman. Later the girl puts her hand back in for a double F. They break up, second woman is now PF'ed. Hands go in and out rapidly. Finally two hands go in (PPF). [15 minutes]
* Strong muscled woman wearing fetish clothes PF's a similarly dressed girl. After some time both hands go in for a PPF. [7 minutes]
There are six other fisting scenes (4 PF, 2 AF).
