Gympregnation - Sex Stories

Gympregnation

... less and less inclined to resist them.

I wandered aimlessly around the gym, slowly working my way toward his ridiculous figure, and then discreetly emptied the vial's contents into his cup while he corrected another patron's form. The formula was nearly tasteless, so he shouldn't notice it under the artificial flavorings in his protein shake. I smiled to myself, realizing that he should be thanking me for the mind-blowing, uninhibited sex he was unknowingly about to have.

A few minutes later he had finished the shake none the wiser. It would take about five minutes for his body to start producing his irresistible new pheromones, so I hid myself on a bench behind one of the leg press machines to record the experiment thus far.

"Excuse me," was the next thing I heard, and, startled out of my note-taking, I looked up into the face of the very trainer I had just dosed.

Not good!

I thought to myself, feeling a brief spike of adrenaline that involuntarily increased my breath rate and blood flow. Everything would be fine, of course, but I needed to extricate myself from this situation quickly to make sure the drug didn't begin affecting me by mistake.

"Oh, just taking some notes for my workout," I answered dismissively.

Why won't he go away already?

"Ah, gotcha. No problem, it just seemed like you were hiding from someone, and I wanted to make sure you were ok." He was so considerate! I was glad I had picked such a nice guy for my experiment. He'd definitely take care of whatever girl he ended up ensnaring with his heady musk.

, I thought, giving his physique a second glance. I'd been too harsh in my first assessment - his muscles gave him a bit of a dominant aura, which was always attractive in a man.

He moved to get up, not wanting to bother me further, and I suddenly felt ashamed of my initial rudeness. He hadn't done anything wrong, after all. "Wait!" I exclaimed unexpectedly, and a little too loudly.
