A strange dream

"Good morning Mark" A beautiful creature arose before him. Everything was white around him save for the creature that met his eyes. "My name is Voluptas. I am the personification of lust, so to speak." Oh, that she was, Mark thought. He had never even seen someone that could compare to her. Her form was ever changing, sometimes she had the biggest chest he had ever seen and in the blink of an eye the smallest. "As you can see, my form is infinetly fluid. It is according to the lust and desires of your kind, and you have no common fetish, therefore I appear like this. But I can shift into a more familiar form, if that would help you". And just like that, Voluptas had taken on the form of his roommate. Mark grew uncomfortable. "Do not worry, meek one. Since I am the embodiment of your sexual desires, I know each and every of your fetishes, of your hidden thoughts. Lust for your roommate is perfectly normal, if not a bit boring. Don't you worry, I am not the goddess of judge. Granted, I am not the goddes of romance either, but that is not what you wished for now, is it? No, what you wished for was total control of your sex, your manhood, your desires." Mark wondered, why his dream didn't end here or why it didn't before. He knew not much about lucid dreaming, aside from the fact, that it is incredibly hard to maintain. And why was he here with this goddess? If he was dreaming, then why didn't he dream of fucking his roommate? He decided that he would do just that and concentrated on summoning her here. "I'm afraid that would only be possible if you had control, dear" Voluptas spoke. "Right now, you are in my realm. You have no power here." "Then what do you want from me?" "Mark, you just made your first conquest out of three. That is all." "Conquest? Of three? What do you mean?" Well," She answered, "You have been granted my power, but it is limited to three impregnations. Once you have done so, your power will be taken from you again. Every power has a limit" "Wait wait wait, impregnation? I didn't do anything!" "Oh but you did! Impregnating your roommate and imbuing your sperm with body-changing properties? Don't you remember? Well, it doesn't matter, until next time, dreamy one." Mark had thousand questions in his head, but he felt himself being pulled away. Then, he woke up in his room. A voice still rung in his ear, although he couldn't make sense out of it: "Go down the path you dislike, reader. Maybe use a mirror."
