There is nothing quite like the image of a woman in a leather straitjacket, particularily a snug one that shows the curves of her body and a bulge where her breasts are confined as well. The way her arms wrap around her body with the sleeves going through a vertical strap over her belly and side straps that keep her from pulling her arms up and over her head. In addition, two straps run along the sides of her crotch, keeping the prime target area free and uncovered for teasing and play.
I imagine her lying on her back on a twin size bed. Leather cuffs around the upper arms are tethered to the upper corners of the bed keep her lying on her back and from sitting up, but with just enough slack to allow her to think there is a little hope of escape. Leather cuffs around her ankles are tethered to the lower corners of the bed, keeping her from pulling her legs up and forcing her to keep them spread apart.
Lying on her back, vainly struggling to sit up and desparately attemping to bring her legs together in an effort to cover the exposed and vulnerable region between her legs. Visualize the image of two leather straps coming up between her legs, not covering anything, linked to the bottom of the jacket and preventing her from pulling it up over her shoulders.
The smell and sound of creaking leather as she tries to wiggle her arms free of their leather prison. The jacket teases her with the false hope of being able to move her arms, possibly reaching the buckle of strap.
My jacket design would also include something in the chest area to provide a little, but pleasant, friction along her chest so that ever movement will hopefully keep her breasts and nipples stimulated.
Suddenly, there is the sound of a steady hum. She looks towards her chest and notices I have hung a vibrating wand from over the bed such that the head is suspended and resting between her legs.
Let her torment begin.
