Damn... this thing's impressive!

You grab a vibrator from your drawer of toys and turn it on, sliding into her ass with little resistance. It sets her into overdrive, her entire body shuddering and dripping with sweat as she cums over and over and over. You can faintly hear her trying to scream 'stop' through the gag in her mouth, but you're pretty sure she doesn't mean it. Her eyes roll into the back of her head until all you can see is the whites of her eyes, and her screams fade into muffled pants as she surrenders her body to the tide of orgasms crashing through her. She loses all control of her senses, with her sphincter uncontrollably clenching around the vibrator as it buzzes violently inside her ass, almost threatening to suck the entire thing inside. A thick waterfall of drool drips from around the gaps in the gag and down her chin, pouring onto the floor beneath her.

You find yourself insanely aroused at the site of the convulsing creature before you, and pull your hardening cock out of your pants. It's been a long time since you've needed or wanted to self-pleasure yourself, but you begin stroking your shaft in earnest, standing in front of Gemma with your cock pointed directly at her. Your hands are a poor substitute for her trio of holes, but you make do, for now, too fascinated by the sight of Gemma's pleasure to interrupt the girl. You start to have thoughts of jealousy - as crazy as that sounds, that the machine might replace you - but you remember that she's a little cumslut that loves to take your loads. Speaking of loads, it doesn't take you long to unleash a stream of hot cum all over her face, which drips down into her eyelashes and clings onto her chin.
