Help her upstairs.

You place a hand on her chair to help her up and are surprised to feel the vibrations of the toy surging through her seat and up the back. Gemma stands, and appears so zoned out she doesn't even put down the fork she's holding in one hand. You pull it out from between her fingers and place it on the table, before leading her toward the stairs near the front of the house. As you head up slowly, step by step, you flick the intensity control on the app to the max, and immediately Gemma keels over, grabbing the railing to stop herself from falling completely down the stairs. As she kneels momentarily on the stairs, you see a huge gush of fluids spray out from underneath her skirt and all over the steps as she violently cums.

You turn the toy back down and help her to her feet, holding her all the way to the upstairs guest room where you push her facefirst onto the bed. You close the door, leaving it slightly ajar so that some light peers through, and grab the hem of her skirt and flip it up over her back. You're greeted by the sight of her gorgeous toned ass, with a gleaming red crystal heart sticking out of her butthole. The pink silicone antenna of the vibrator dangles out of her pussy, bouncing ever so slightly with the rumbling of the toy inside of her. You strip off your pants and set the vibrator to an automated setting, freeing up your hands to grab her by the hips. You slip your cock between her legs, pushing aside the antenna with your shaft, and rub your head up against her slippery wet clit.
