And what a bang to start with, a full-on actual ahegao face!
What's the deal with her getting off when they're pulling up the zipper though? Are tight corsets something a woman can get off with? Is it a nipple thing, a bondage thing? All I could make out happening is that the outfit got really tight over her chest and apparently that was literally orgasmic.
Is it supposed to be a real thing that could theoretically happen, or is it just as random and weird to other women?
