This week I put on my lab jacket and went around to collect the semen samples that I needed for work. My first patient LOVED my outfit and I knew that getting my sample was going to be easy and fun! I took him into his living room and showed him my huge tits to get him started - then I had him sit down while I took his cock into my hands and started licking and sucking his hard cock. He responded immediately, moaning and twitching while I worked his big dong. Soon I was coaxing his "sample", savoring every drop.
