Point your fist up.
From Create Your Own Story
You point your fist up and successfully penetrate the general's asshole but it does no good because his butt cheeks are too big for him to feel anything.
Being penetrated by your fist, the general turns his body by 360 degrees, breaking your arm with his huge body weight.
He stands up and your fist exits his ass - you lie on the ground, needing a few minutes to calm down from the huge pain in your arm area.
The Nazi general thinks you're dead and turns around, leaning on the counter, which almost breaks it.
