Nurse sucks dick for sperm sample

I had a real weird case today. I had this guy come in and tell me he's been trying to get his wife pregnant for two years! We talked about possible solutions for awhile, it could be any number of things! I got to the point though, I said I'd need a sperm sample to test properly if it was that, which would be the most likely. He went out for a bit and then came back in saying he couldn't do it! I'd got so fed up by this point I just dragged him back in to the toilet and gave him some encouragement! I got down on my knees and started sucking his dick! After a while I could see he would need a lot more...so I pulled up my skirt, pulled down my panties and let him fuck me from behind! That really got his heart racing! After all that encouragement, I finally got a sample! All in a days work!
