I finally managed to coerce Benny into coming over to me, though he still was acting fairly timid. I rubbed my crotch with my fingers, getting them good and damp, then offered them to Benny for inspection. Benny's tongue quickly began to lap the juice off of my fingers, and he seemed eager for more.
I laid down on my back, letting him perform his oral ministrations on my vagina, reveling in the purely bestial way he gave cunnilingus. With every lick, I felt myself getting wetter, and felt a force building up inside of me, growing stronger by the second.
I began to growl as he continued, moaning for more. I was vaguely aware that my hand had begun to throb again, but I didn't care; I was so wrapped up in the moment with Benny.
I felt an odd tingling sensation on my chest, however, and that distracted me long enough to look down, and see wisps of hair beginning to grow on my chest. I glanced down at my throbbing hand, only to see more hair growing on the back of it, as well as new talons sprouting. The same thing was happening to the other hand now, I saw. As much as it defied reason, I was turning into a werewolf.
Even more unbelievably, I was wanting it. I pulled away from Benny, rolling back onto my stomach, offering my ass to him, raising it in the air. "Do it, Benny...make me the beast!" I growled, feeling teeth that were too big for my mouth.
As confused and timid as Benny had been minutes before, he was equally confident now. He didn't need any encouragement from me to do simply what nature told him to do.
"Yesss..." I growled as he entered me, humping madly away, his nails stratching me as he did. I concentrated on forcing the beastial change to continue. I had never felt so free, or so powerful as I did while I was transforming that night.
I could feel the extra breasts popping out of my chest and stomach, and I watched fascinated as my hands completed their change into paws. The wet popping sound of my bones reforming only served to arouse me more as I urged my inner beast on, wanting to be free of any vestige of humanity.
Amongst my last conscious thoughts that night, I wished for two things. I wished that I had been able to see the whole of me transforming, and I wished that I had someone I could share the whole experience with. Because, while Benny was fun, I knew another human would be moreso.
With a final pop, however,my snout completed its outward expansion, and my tail emerged from my skin. With a final howl of joy and exstacy, I bid my humanity farewell.
I wasn't really sure what had happened the rest of the night, until I woke up the next morning, naked and sore in the backyard.
