Women's self-defense course

As you stagger about doing your morning rituals, you remember just why you had to get up this morning, despite it being Saturday; your long-time friend Monica is runnning a women's self-defense course, and has pestered you into helping out as someone to demonstrate on.

You owe her a few favors, so you've ended up signing over your next few Saturday mornings. It shouldn't be too bad; since she's only demonstrating, you won't get hit for real or anything.

Dressing in sporting gear, you drive over to meet Monica at the community centre venue for the course she's offering.

Monica is a pleasant brunette, a bit under average height, and with a fit, yet still distinctly feminine physique.

"There you are! Just in time, all my students are here!"

She greets you while gesturing into a large room filled with exercise mats, where about two dozen women, looking like a mix of housewives and college students are gathered.
