Gina uses three fingers

She groans, and teases her nipple with the other hand, lightly pinching and circling it, making it even stiffer. As she does this, she slides two fingers smoothly, with no resistance, straight into her hot, slippery gash, frigging them in and out, with speed and skill. Her inner lips open up, gripping her fingers, and we can see a hint of the slippery pinkness of her cunt, and hear squelching noises as she finger fucks herself, adding a third finger for extra width and pressure.
