Hard and deep

I teased the doctor's anus at first making sure I had plenty of my fingers well lubed up. I then withdrew and feeling him trying to ease them in, he wasn't expecting what I did next as I thrust my hand hard against his pink lips, slipping four fingers inside up to the base of my thumb. He yelped and groaned and I eased off before bending my thumb into a fist, ramming up inside his wet undulating sphincter. My hand slid inside easily and the doctor bore down on my arm wanting me deeper and harder. His hole opened up to me and I was quickly in up to my wrist. "Yeahhhh!" the doctor cried out, the hot muscles contracting inside him pulling me in further. His cock twitched, his balls contracting and I pumped my fist, filling his tight sphincter. "Deeper!" he said as I angled my arm for him to ride. He was half way up my forearm when I felt his internal sinews grip me firmly, and with a huge shudder his balls swelled, his erection throbbed and a heavy stream of cum erupted from the engorged tip of his aching cock. I slammed hard into him intensifying his orgasm. The doctor still had his hands inside Andy's hole as his body shook all over, his spasms made Andy moan again, the doctor was obviously going into him harder as his powerful orgasm began to subside. Huge globs of his jizz spattered Andy's hole and the doctor pushed it inside with his hand adding to the lube and other fluids mixing around his engorged ass lips.
