Stud caught giving nurse a creampie

I was looking after the doctors appointments whilst he was out of office when in sauntered this very handsome looking young man. He told me that whenever he has sex with his girlfriend she always ends up finding the experience painful. His girlfriend was in the waiting room, but I wanted to see what this stud was packing before I called her in. I told him I would need to see his penis to make sure the problem wasn't with him. He undressed and sat on the examining table with his cock out. I quickly got to grips with him and I had soon wanked him to his full hardness, all the while telling him that I thought everything looked fine to me. I told him I would test it with my sensitive mouth to see if there was anything I was missing with my eyes and hand and he readily agreed. I sucked him deep into my mouth, rolling my tongue all over his tasty head. I then suggested to him that he should show me a few of the positions that he fucks his girlfriend in, so I could see if he was doing anything wrong and if he would cause me any pain. This was working out beautifully and this stud had impressive stamina as he fucked me in a few different positions, because I had to be sure of course. My sexy nurses uniform eventually beat his ball control however, as his excitement levels peaked and he shot a load of his man jam deep inside my pussy. As he pulled his cock out a big dollop of population pudding bubbled out of my pussy and slid onto my thigh. Before we could really catch our breath however, his girlfriend walks into the room unannounced and catches us with my legs in the air and cum pouring out of my pussy and him naked from the waist down. She stormed out and I knew I had to act quick, this was going to take all of my skill to talk myself out of this situation. I need to find the girlfriend and quickly.
