You've had a medical problem for while and, unsure of what to do, you finally give in and take a visit to the Doctor's surgery. You soon realize what a great idea it was when a cute, young nurse sits down next to you and tells you that your only problem is that you haven't cum for a while. Her fingers stroke your hard cock through your jeans while she explains that she could call in a colleague to get the job done... or she could use her body to help you. You obviously pick the second option and soon her hand is wrapped around your cock and you're leaking precum. She tells you perhaps you'll be able to get rid of more cum if she sucks your cock, so begins to work her red lips up and down your length. You get carried away, holding her head down on your cock, and fucking her mouth until she agrees to let you fuck her... on one condition, you can't cum inside her as she has a boyfriend (and can't get pregnant!). You fuck her hard and deep, losing control in her tight wet pussy and using her to edge your hard cock over and over again before you ask once more if you can fill her up with cum. She refuses and begs you not to so you pull out last minute, but instead spill your huge load all over her dripping wet pussy. She's so turned on by how much you've cum, and the fact that it's coating her folds - that she starts to play with herself. She scoops your orgasm down into her hole anyway, ignoring her concerns, and starts to finger herself, using your cum as lube, until she brings herself to a shuddering orgasm.
