Erika felt a strange pull towards Cole. It wasn't just the musky scent emanating from his groin and the carpet, which she could smell across the room. His own scent seemed different also, and slightly intoxicating. Perhaps this is what Melissa experienced when Erika was around...
Cole stood and pulled his pants up. His now larger package filled his underwear and created a decent bulge to the gazing eye. Erika had to force herself from staring, fighting the rush of hormones in her body.
She led Cole to the bathroom so he could clean up a little, and picked up the hair dryer. Once back in her room she carefully avoided stepping on the wet carpet to pick the diary, and began blowing hot air between its pages to help it dry. When Cole returned, she handed over the hair dryer to him and excuse herself to the kitchen to prepare lunch for the two of them. Her body was still sensitive to Cole's pheromones or whatever magnetic animal pull was in play since the salve, so she felt it would be better to stay alone for a bit.
By the time Cole came down for lunch, she was feeling better even though she could tell her mutant clitoris was inevitably grewing by the hour. Over their food plates, they decided for a plan of attack to solve the mystery of the salve and find a solution together.
Once back in her room, Erika opened the window to vent out the musky scent, and she sat at her computer to research dog breeding and complex words as Cole was reading out lout the few passages of the diary book that were not illegible. While most of the pages had been too waterlogged to be salvaged, some parts they could still read, even though they had trouble making sense of it.
There was a sense of mystery and excitement that was starting to overcome the looming feeling of fear and shame; both Cole and Erika were captivated by their little quest. They were also learning about reproduction and sex by googling every new term they encountered, and the sense of danger and teenage rebellion in doing so was thrilling.
"So" Cole said after a few hours of intense research had passed. "This is a list of things we have mostly figured out:
"The guy who owned the journal was into breeding dogs and had come into possession of one or more salves. No clue about where it originally came from so far. This salve we found is meant for male dogs.
It is supposed to increase all sexual characteristics in subjects, and some other traits; some for the looks, and some for better breeding like the sex drive, pheromones, penis size, amount of cum and such.
The effect of the salve such as the sex drive is only satiated by breeding or orgasm so as to encourage dogs to breed more. The cum is slightly addictive.
The substance is likely still experimental, untested on other species, and unstable on members of the opposite sex."
"Duh" Erika let out, "in case I hadn't noticed". Cole kept on going over his list, while Erika was taking mental notes. There apparently were other salves in existence, including one supposed to dispell the effects of the others, but she had no clue if it was the vial she had hidden in her bag.
Her train of thoughts was more and more distracted as time went by, her concentration breaking as the subtle changes in her body were progressing. It had been hours since her last release, and the need would become more pressing. In fact her groin felt warm and swollen under her dress at this moment.
She interrupted Cole to excuse herself. "Alright, that's enough for now. We did a good job but I still have to get ready and go back to your house; Melissa and our friends are waiting for me so I'll go change myself".
