The dog picks up on my desperation, his thrusts becoming more frantic as he pounds into me with all his might. My ass clenches around him, milk beginning to drip down my thighs as I lose control. "Oh god!" I cry out, arching my back and digging my fingers deeper into his fur. The sensation is unbelievable, like nothing I've ever felt before, and with one final thrust, I'm over the edge, my body convulsing as I release in a powerful orgasm.
