"Hey Uncle Max, it really is me, your nephew David", I tell him. You then start to explain to him what's been happening over the last couple of days.
Max looks you over, then his eyes shift to Ross and Jack curled up and sleeping peacefully next to you. "This is really hard to believe David." "How could wearing a bear costume turn the three of you into werebears?", he asks. You tell him that Jack started it and once he was changed it spread to you and Ross.
I could tell the pheromones were starting to work on my uncle by the increasing bulge in his pants. I reach over and start stroking his full thick beard. He really is a handsome man I think to myself. I can feel myself starting to become aroused again so soon after my marathon sex session with Jack and Ross. Max is rubbing his own crotch as I continue to explore him. He stands up taking off his shirt to expose his already hairy chest. His muscles are well defined under the light brown coating of hair. Years of exercise in the marines have really paid off for him. Max drops his pants, showing his large thick 10" cock. My mouth begins to water as you think about licking that big piece of manmeat.
"So, you want to suck my cock don't you?", he asks. I nod my head and lean over to take the large bulb into my mouth. Max groans in pleasure as my long bear tongue begins to work it's magic. He looks down at me and asks if he'll become a bear like the three of you. "Only if you take some of our cum in your mouth or ass", I tell him. "Okay, we'll see", he says. Uncle Max is soon bucking his hips shoving his cock further and further down my throat. I can smell the heady aroma of his crotch and it's really turning me on. By this time, Ross and Jack are awake watching me give my uncle a blowjob. They start caressing each other again and the pheromones in the room are overpowering.
Max is beginning to moan louder now as he is ready to blow his load down my throat. His large balls are filled to capacity and need the release. I nod my head telling him I'm ready for it and in a loud roar he empties his manseed in my mouth. My big bearcock is needing release too as I continue to run my paws over Max's body. Moving over to make run for him in the bed, I start playing with his furry ass. Precum is streaming from my dick and putting some on my hand, I begin to slip my finger up his tight hole. Max moans slightly at the intruder in his virgin manchute, but I keep going and soon he is wet and slippery and more than ready to take my cock. Positioning myself behind him, I slip the big mushroom head in and soon pumping for all I'm worth. I know that once I empty my bearballs in his ass the changes will begin. My load continues to build and soon there is no holding back. With a loud roar I explode deep inside him. Laying there panting, I watch as my uncle's body begins to enlarge and fur is spreading rapidly across his broad shoulders and back. I smile, and think to myself, yes, another conquest. Max rolls over and with a smile on his bearish face says, "I tried it and I do like it"
