As he reached for his clothes I meekly suggested that he go take a shower first, since washing off the pheromones would likely decrease his chances of affecting another woman. He had already lost interest in me, however, and, after pulling his shorts over his half-erect dick, he stumbled out of the room without a backward glance. That didn't bode well. I didn't know exactly how long the effects of the dose I had given him would last, but until he washed it off, any woman within smelling distance would quickly become just as eager to let him cum inside her as I had.

When I had put myself back together enough to painfully hobble out of the back room, I saw the trainer talking to a gym bunny on the elliptical with massive fake tits, barely contained in a tight, revealing tank top. I could tell that her body was already responding strongly to his powerful masculinity: she was hanging on his every word, taking deep breaths of his enticing, addictive musk, and I knew that she was becoming more receptive by the second, both physically and mentally, to being impregnated.

Her fertilized body would reprogram her into his breedslut, just as I was, and she would be discarded, just as I had been.
