Grace goes to Candy's house and after an initial discussion, curious, she accepts her unusual proposal to be subjected to fetish/BDSM games.
Grace wakes up on the bed, with Candy smiling and caressing her. She immediately thinks the first game was a bit risky, but despite that, she found it very pleasurable and decides to continue submitting. Candy grabs her neck with a gloved hand, then she uses it to cover her mouth and nose. Then again, she covers her mouth and nose with one gloved hand and squeezes her neck with the other one at the same time.
Grace also finds this game enjoyable, so Candy decides to get serious. Holding her in front of her, she grabs her neck with a gloved hand and repeatedly she handgags her in a hard way, continuing this kind of domination for several minutes. Grace, of course, isn't scared at all and finds it all very pleasant.
