I instruct her to adopt the downward dog position (Pink Trigger)

If you've ever watched yoga instructor porn before, you know that the downward dog is the holy grail of yoga. It's what all perverted yoga instructors aspire to reach. In this pose, a woman is fully ****, with her ass in the air, just like the name-sake dog. I had to see it. I asked her to take the pose, trying to keep the desperation out of my voice.

And she did. Eva formed a perfect- and I mean perfect- upside-down V with her body. I couldn't help but gawk at her ass in those yoga pants... It looked like it wanted to split the pants open and escape, if I didn't get to them first, that is. I told her she had flawless form.

"You're sounding less like my instructor and more like my groupie, Doctor."

I couldn't deny that. Now, to initiate docking... I placed both hands upon her hips from behind, telling her to keep steady, just like that. I warned her that I was going to be touching her butt for just a moment. She gave a scoffing laugh, as though saying of course I was going to touch her ass. With no hesitation I cupped my palm there and ran it along the curve, appreciating the roundness of her bum, as well as the perfection of her yoga technique. I asked her to hold that pose.
