Nurse Abbi has been working hard all day and when I finally saw you I knew you were the one to let a little steam off on. The appointment goes as usual in the beginning but when I mentioned a genital stimuli test I could see how intrigued you were. First I start off by sliding your cock into my mouth so I can feel every twitch and tremble that your shaft gives to me. After you've been properly sucked that's when the real endurance tests begin. How long do you think I can ride you before you're ready to fill my "sample" cup to the brim? Let's find out together!
