Alien impregnation made me call in sick

I was working late when the alien spaceship descended from the sky. As I watched in horror, a tentacle snaked into my office and violated me, thrusting its thick, slimy length deep inside me. The unbearable pain was accompanied by an intense heat that filled me with terror. The alien's seed began to grow inside me; it felt like my very insides were being stretched and transformed. My screams echoed through the empty office building as the alien slowly, methodically filled me with its seed. When I finally collapsed, exhausted and in agony, I knew there would be no going back to work tomorrow - I had been irrevocably changed by the alien's impregnation.
