(This was originally filmed as a custom video) You're visiting a fertility clinic to give a sperm sample as your wife and you are trying for a baby. When you arrive the nurse who comes to check you in turns out to be your wife's best friend! You had forgotten she works at this clinic! She's surprised to see you as well and says she hopes it won't be awkward giving your wife's best friend a cup of your sperm! She leaves to give you time to collect your sample but comes back too quickly and catches you with your cock still out - she's embarrassed but notices that your cock is staying rock hard as you look at her, and she slyly suggests that if you're having trouble getting your sample then maybe she could give you some inspiration...? She strips off, admitting she's always found you attractive, and gives you some light JOI while she shows off her naked body for you. But soon she's gotten too turned on watching you stroke your cock, and she asks if she could help you out even more. She gets down on her knees to use her hands and then her mouth on you, then after a while admits she's really wet now and is desperate for you to fuck her! She rides your cock, her dirty talk getting filthier and filthier, then lets you fuck her in missionary and fill her with cum, while she begs you to leave your wife for her! After you've cum she says you'll just have to come back another day to give your sample, as this one is deep in her pussy right now!
