I've discovered Saki Okuda's "intense orgasm" sweet spot! For a girl who says the way she feels sex depends entirely on the man's technique, I gave her intense piston fucking, and the moment she came, I hit her with intense piston fucking again! By repeating this, I let her experience a heaven of continuous climaxes. Saki-chan was confused at first, but after being completely fucked into submission, she ended up desperately begging for more herself.
