Wedgie atomică

For some reason the sub has decided to wear underwear today! Miss Wildfire is not impressed. So, she has a cruel and humiliating punishment for him. When inspecting the underwear, she gives a hint of what she has in mind as she pulls up the underwear to give him a wedge as great as she can. With the elastic tight, she spanks his arse. This is sore and humiliating, but also involves effort. She has a crueller idea which will involve less effort. She clips a carabena onto the underwear, which is attached to a winch. She can turn the handle and it gives him a wedgie and holds it in place. She stretches out his arms and cuffs them to the bars of her frame. This gives her more access to his body as he is impotently strung up. There is no let-up - it is cranked further and further - bringing more hurt, more discomfort and more torment... and she will keep going. What will break first - the underwear or everything they're squeezing underneath?
