I grabbed my dog and gently start massaging her tight butthole. It looks so juicy... i've always wanted to try her out... With my fingers I begin to stretch it wider. I spit on her for lube and she whimpers, that sound turns me on so much. I wuickly manage to place my whole thumb into her slippery hole. I pull it out after a bit, so excited to finally be doing this, and it smells strange. I rip my pants off and place my cock on her bumpy, dark skin right below the tail. 'Good girl...' I whisper as I hold her torso and slide myself in. 'Nghhh-' oh god, this bitch feels so good. My dog's 'pussy' is tighter and slimier than any human bitch I;ve used. As I thrust and hump her, I realise that I know who I'm gonna b fcking for the rest of my life ;)
