You're required to give a sperm sample but are taking a while. You're hardly to blame when its such a clinical environment with nothing to stimulate you. There's a queue outside so your favorite nurse knocks on the door to check on you. Nurse Lucy asks if its ok for her to come in and despite being a little embarrassed about the situation you agree as she is a medical professional and you quite fancy her anyway. She asks if you need any sort of help. She needs the room for other patients and seems to be flirting with you which is actually helping your dick get hard instantly. She notices and seems to get into it slowly teasing you, gradually exposing more of her red lingerie and stockings underneath her uniform. She tells you her favorite part of her job is being naughty for her patients to help them along with depositing their samples. Gently guiding at every step of the way, you put your hand around your cock as soon as she tells you, squeezing and moving at the speed she instructs. She takes of knickers and bra teasing you by spreading her pussy and butt cheeks really close to your face. Her dripping wet pussy gives away the fact she is extremely turned on, ready to masturbate along with you. She pulls out a medical instrument to use as a dildo and still instructing you every step of the way counts you down so you orgasm at exactly the same time. Extremely pleased with your huge donation she leaves you to clean up but urges you come and give her another spunk deposit all over her tits next time!
