She cums all over you

"Oh God, I'm about to cum," she shouts. Her pussy gives two half throbs and Julia lets out a cry and jerks her hips. One hand grips you and greedily crams you into her just as the orgasm hits. "OooooOOOOHHH!" she shouts, her voice getting higher and quieter until it's a squeak, her thighs pulling together, and her pussy clamping down on you. The crushing grip lasts for two seconds before momentarily relenting and then crushing back down on you again. You begin to wiggle and struggle as hard as you can while being squeezed, pushing hard against her g-spot. "Oh- Oh- OH-" she grunts again and again as another wave of orgasm rocks her body. "Ohhhh fuck!" she whispers, and her pussy clenches your harder than ever, making you see stars as it pulses against you. When your wits return, you're still mostly in darkness, surrounded by her walls. You can hear Julia through her flesh, giggling and panting, still getting hit with little splashes of pleasure here and there-- particularly when you move.

"And that's," she says, still panting, "how you please a giantess."
