Continue hands-off (Pink Trigger)

Any good yoga instructor knows you can't just jump onto the gal you're training and start humping her. That didn't mean I couldn't enjoy myself, of course. Keeping that stance, and telling her to do the same, I pulled my penis out of my trousers and replaced it where my hand used to be. Would she notice? It seemed not...

Pushing my luck further, I rubbed, tracing that same curve again. Ah... Eva's ass-cheeks were cradling my cock. I wished I could have gotten her to move as well, but I had to be as covert as I could for this path. The wonderful thing about yoga pants, as any hot-blooded male will testify, is that they allow women to retain the modesty demanded by society without actually hiding anything. I appreciated that at this moment. I could feel the full shape of the lady's ass against my member as I stroked it up and down, moving just my hips.

She'd begun to catch on, as anyone would.

"My form must be pretty off this time, eh, Doctor? You're spending an awfully long time inspecting this one."

She had a fair point, but it didn't matter. I could feel myself pushing to release. I ensured her everything was fine, just keeping holding this position, keep holding this position. I wasn't holding anything at this point; I rested both hands above my head, willing myself not to grab that ass, while I continued to jerk my rail up and down the ass-crack of her pants. Finally, I reached completion, releasing my load onto her back. All hands-free. Even with the moisture, it would probably take her just a second to figure out what I'd done. I groaned in satisfaction.

Crap. Didn't mean to do that.

"Hmmm? What was that?"

I informed her I needed to use the bathroom. This would be my time to regroup before she noticed the cum on the seat of her pants. Who knows? Maybe she'd even be flattered once she did.

With this optimistic thought in my head, I ran to the bathroom. This was a mistake. Never run in your bathroom. Before I knew what had happened, I felt myself slip and tripped headfirst towards the toilet. If this was a cartoon, I'd probably find my head stuck in there. Ha ha! The lame pervert got his head stuck inside a toilet.

Instead, my head collided with the hard toilet-seat. I felt myself concuss, then felt nothing further. I had guessed something like this would happen, but I really didn't want to die with my face here on the bathroom tile... Even I have some dignity.
