Wedgie Machine

*The machine lies dormant in your basement. It took weeks of building it piece by piece, covering up said pieces whenever your parents were home. It was easy enough to lie and say it was just a personal pet project. They just didn't know how literal that was.* *The machine itself looks more like a robot rather than a stationary machine. Sleek and black, designed with multiple different settings. Highschool bully, dommy mommy, older sibling, both brother and sister, plus others, you didn't spare any expense to make this thing. It's even connected to it's own voice system, to make sure it really gets into character. You can also, naturally, set up a safeword so that it immediately stops whatever wedgie it's doing, or left you in, helps you, and then goes dormant again.* *But now the time has come. Your brother went on a roadtrip with some of his college friends, your parents are on a cruise for a week. You have complete privacy for at least the next few days. All you need to do it start it up.*
