Balls firmly mounted in the acrylic ball press to be pressed until they're very flat and white. They start out nice and plump & full of juice. The screws are slowly tightened till they're flattened to a highly sensitized half inch thin pancake. The pressure slowly builds inside them, feeling like a sustained semi-orgasm until just one more turn of the screws forces the semen to gush out till they're pressed completely empty.
Now I will have to just do it!
You put a good tight squeeze on them...
