Mary's mouth hung agape. In front of her, a terrifying creature is jacking itself off with reckless abandon. As it beats away, it doesn't notice Mary, allowing her to take in its form. It looks part man, part dragon. Actually, it likes like two-parts man, one part dragon. It's body could easily overtake the width of two men. It's scales are a navy blue, and glisten in the light. Two heads stretch upward, both pairs of eyes closed, enjoying their self-pleasuring. Any taller, and the long, back-pointing horns on each head would be tearing holes in the ceiling. A tail thrashes out against the table the serpent man is standing in front of. Mary's eyes go wide when she looks at the appendage the dragon is paying attention to. It's angry, large, red, and tapered. It looks thicker than her legs and longer than her arms. The dragon is using both sets of its claws to stroke hard and fast, being rewarded with a constant stream of pearl-white precum. Both heads are tilt back, with a clenched snarl. Mary feels petrified at the sight of the creature, and wants to sneak away. Suddenly, both dragonic heads let out another roar, just as deafening as the last. The dragon's stroking turns into bucking as it's penis begins to pour more and more precum. Mary realizes what's happening and practically jumps out of the way.
A thick rope of cum jettisons from the dragon with enough force to hit the wall on the other side of the room. It's followed by several more ropes which fling forward in rhythm to the serpent's pumping and humping. Mary watches with a mix of disgust and fascination as it releases its thick and potent seed into the world. On each head, their eyes are clenched. Both jaw's are hanging open, taking in the full orgasm it brought itself. Eventually, however, the moments between each rope lengthen enough to end the orgasm. Both dragon heads lower their gazes and open their eyes. Their stern looks lazily roam the room, until one and immediately the other lock eyes on Mary, standing quiet against the wall. The dragon smiles with both heads, and puts his left claw on his hip. The right claw remains on his penis, slowly stroking to keep an erection.
"Ah, Mary!" Both heads boom in unison, in the same tone and tamber. The deep, baritone voices frighten Mary, and she takes a step back. At this, the dragon laughs with both heads in satisfaction. All the while, his left claw is still nursing the throbbing erection.
"Ha! You don't recognize me?" both heads boom again, and laugh again at the confusion on Mary's face. "It is I, or was, your parents." Both dragons smile with their razor-sharp teeth, and wait for a response from Mary.
"B-but, that's impossible!" Mary finally speaks, "My parents are human! My mom is a woman!" At that last statement, the left head laughs first, which the right head joins in with.
"Oh, but it's not impossible, thanks to you, Mary." The two-head dragon continues, "Thanks to those amazing dragon-shaped candies you left on the table." With that, the dragon stomps towards Mary, who starts to run away. The lumbering dragon ignores her however, and grabs the container of dragon-shaped candies, which were on a table behind Mary. There, it uses its claws to scoop out a handful of candy. It sets the container back with an odd sense of care and puts itself between Mary and the container.
"It's true, I am your parents." Both heads say again, "I'm Robert." The right head proclaims in deep baritone. "I'm Melissa." The left head repeats in the same baritone as the other head. "Or at least we were until we ate a blue dragon candy." The dragon's left claw resumes pumping its red rocket as the right head speaks.
"I convinced you mother, in an act of love, to split a blue piece of candy with me. After we both ate our half, we grew extremely aroused with each other. When we embraced in each other's arms, we fused together. At the same time, the blue piece was making us both into male, anthro dragons. First our scales fused, then our body, and then our minds. The only real difference is which personality dominates which head." The left head joins in at this point and says with the other, "Even then, a new being, a dragon, the one who talks to you now dominates. I am not Robert, I am not Melissa. Together we are more. Together we are me." With this, both heads laugh in unison, the dragon's words fueling its own pride.
"But either way," the heads speak in unison again, "I should thank you. Without your candies, I would still be just Robert and just Melissa. Therefore, I will make you my mate." At this, Mary's eyes go wide. The last thing she wants to is to have sex with her parents, even if they're the same person, or dragon, now. She books for the exit. The dragon says nothing, but leaps towards Mary, and knocks her to the ground. Once Mary is down, the dragon rolls her over and pins her down with only the claws of his feet. As Mary looks up, she's greeted by the sight of her parent's penis, dangling a foot above her. To make matters worse, the dragon was still stroking it, making precum leak and travel down the shaft to its base. There was no way she was getting out of this.
"However, I do not want a human as my mate, let alone a remnant of my past lives." The dragon's heads smile as it drops three individual candies on the floor ground Mary.
"So, I offer you the choice of candy. Red, Blue, or Black." The dragon's heads then sneer, and take on a more forceful tone. "And if you refuse, then I shall choose for you, and I will not be merciful with my breeding." At the same time the dragon's heads utter the word 'breeding' in unison, his cock twitches in excitement.
Mary turns her head to face the candies. She has to make a choice, or he will. Is there any way out?
