The teacher

You focus your attention on the Yoga teacher, a petit woman with long black hair tied back in a pony tail dressed in a lime green crop top and blue leggings.

Slowly she leads the group out of Cat-Cow and back into Downward Dog, raising her arse high in the air as she does so.

You slowly move around behind her, watching her thrust her round arse up towards you.

"And now Standing Forward Fold!" she called to the group, bending over and hugging her ankles. It's far to tempting a target and you use your powers to cut a slit across the arse of her leggings, the fabric slowly parting to flash a pair of white panties underneath.
