Once I was done working over Justin I thought it was more than fair that he repay the favor. I had Justin get on his knees and work over my cock. He shoved it in his mouth and started to bob up and down while taking it deep down his throat. He was staring up at me while I thrust forward, my dick filling his mouth.I laid back on the exam table and as he continued blowing me. Justin then brought my legs up and began to eat my ass. Justin's tongue probed my hole, nice and deep, sending waves of pleasure up my spine. His mouth went up to my balls and then started to suck on my cock again. I could feel my orgasm building as he continued to suck hard. I felt my throbbing member unload all over this new patient of mine. I told him he might have to come back for more test and by the smile on his cum covered face I could tell he didn't mind.
