Today was the medical check - up day. John went through all the tests except for the last one, which was behind some hospital curtains. He was the last in the queue. Then, when all the other people had left, he went in and saw a beautiful young nurse sitting down. She had big breasts and was wearing a tight - fitting white dress. He stood next to the table and the nurse could not help staring at the bulge in his pants. Then, she stood up and said in her sweet voice, "For the next test, you have to fill up this bottle."
"With what?" Tom questioned, looking straight into her beautiful eyes.
The nurse replied, "Emm… With your urine, in there." Said the nurse as she replied Tom's stare and pointing to another set of curtains. Tom walked into the curtains and saw an empty room. He closed the curtains. He knew he could fill that small bottle up with his urine as he had drunk a lot of water in the morning. But he was trying to get the attention of the nurse. After a while, he returned from behind the curtains holding an empty bottle. He said, "I cannot fill this up." The nurse did not seem to know what to do, as she did not reply. Then, finally she said, staring at the growing bulge in Tom's pants, "You have two choices, one is you go to the canteen and drink some water so as to fill it up, or……" the nurse seemed to pause. "Or…" Tom said. "Or I will have to help you fill it up." She replied.
"I will take the second choice." Was Tom's reply. "Then, pull down your pants." She said. Tom did as he was told. "And your underwear." Tom put his hand in his underwear and pulled his now erected prick out. The nurse, staring at it while she walked over, started to massage his cock like she was milking a cow. John enjoyed it very much. At first, some of his urine came out, then, a huge flow of urine spurted out, and the nurse massaged even harder. Then, Tom let out a string of cum. The nurse said, "Oh no! You've polluted the urine sample. Before we start filling it again, I want that huge monster in me!" Then she stripped herself and exposed her huge breasts and vagina. John sucked her erected nipples and thrusted on her a few times, each time going harder and faster, the nurse drinking the sample at the same time, finally they cummed in each other. Then they once again filled up the bottle.
