It's always been a fantasy of mine to be a sex slave for 2 bears, male and female, pleasing the male when she's tired, and vice versa. Slowly sliding my lips up and down his thick shaft, tasting his pre-cum on my tongue. Once he's had enough of that, he rolls over onto his back, lifting me up as though I weighed nothing. Gently placing me on his cock, I guide him in, feeling him stretch me wide open. I moan with pleasure, feeling him fill me up. He growls softly, I feel it rumble deep in his chest, vibrating all the way down his body and through mine. He continues to lift me up and then pull me down. He's doing all the work for me, it feels so good, the warmth of the fur, his paws either side of my waist. He is in total control, I'm just nothing compared to his vast size and strength, but I have total trust in him, I know he won't hurt me. I feel the pace quicken, almost imperceptibly. I slowly stroke myself, feeling myself nearing the point of no return coming closer with every stroke. I can hear the growl getting louder now; he speeds up even more, forcing me further and further down onto his thick cock. If it wasn't for the fact I my body is releasing so many endorphines, I would probably be screaming in agony. Except I am panting and whining, just like a bitch, begging her mate to fill her up. His claws dig in deeper, the pain, its excsquisite. It sends me over the edge. My head goes back, I let out a short grunt, I feel my cock explode, covering his chest fur in my seed. I keep stroking, it looks as though I'm trying to rip my cock out. I let out another grunt, another torrent flows forth, then another and another. A drop lands on the beasts muzzle. He seems confused for a moment. That's what I think. He digs his paws in even harder now and slams me onto his cock, I feel his grumble turn into a roar. He's cumming, oh my god. I can feel in, filling me up. It's undescribable. He's mating with me, he's claimed me. I feel him slow, his cock still throbbing within me, it seems as though there's no more room for his cum. It's dripping out of me, onto his fur. I reach down, and then bring my hand up, tasting him. It's more than I ever expected. It's heaven.
