You nearly screamed when you saw the bumps on your brow and your green eyes glowing softly. You were transforming into a demon! Tears began to spring to your eyes as you began to picture yourself as a demon, killing and raping others. Inexplicably, you felt your cock twitch at the thought, which made you cry even more. Now to tired to shower, you throw yourself in bed, wanting to wake up and everything be fixed. It wasn't long before you drifted to sleep from pure exhaustion.
In your dreams, a bitch lay before you, ass raised, legs spread, waiting for your cock. You obliged, gripping your fat cock (was it always that big?) and shoving it inside her tight hole. It slid in with a wet sound and she moaned, hands gripping the sheets. You began to thrust, gentle at first. Then her noises seemed to drive you mad and the slow pumps seemed inadequate. You begin slamming into her, hard. She starts howling, begging and screaming for more, then for mercy. You don't stop, and you can hear your gasps turn to animal growls. You wanted to hurt her, grip her hips until your talons made them bleed. Wait, talons?
You woke with a start, immediately noticing the sweat that covered your body and a pain in your groin and skull. Panting, you remove the sheets from your body and see your cock, easily 8 inches long, pulsing with need. It had doubled in size! You needed to touch it, release all the built up pressure. You take the needy rod into both hands, toes curling at the sensation. You give it a pump, and your back bends compulsively, the pleasure forcing an animal sound out of your mouth, like a cat in heat. Encouraged, all human rational thought gone, you begin beating your meat wildly, bucking your hips and howling madly. You hear a fist beat against the wall, an angry voice telling you to keep it down, but you don't care anymore. In fact, you feel your cock grow and produce more pleasure, egged on by the embarrassment of others. In turn, your moaning becomes louder, more desperate for attention. Your muscles bulk up very slightly as your cock and balls inflate. You watch in absent minded awe as your dick grows ridges and bumps like the other demon's, curving and tapering at the tip and starting to glow a faint red. You feel pressure in your brow as your horns grow, bigger then the demon that caused the transformation, the hard bone growing in a spiral around your ears, like a ram's. Your cock grows a little thicker, and a little longer, the grow stopping at 12 inches. At the sight of a drop of glowing white pre on the tip, you give a scream as you climax suddenly, unable to resist the sight of your new inhuman seed. Your cock throbs violently as your balls jerk up, shooting a thick stream of demon cum. It spurts a few times as you writhe with pleasure, panting and sweating like a tortured animal.
Another shout and pound on the wall brings you back to your human senses, and your heart begins to thump as you realize what you've done. You've advanced the changes! Your hands fly to your head and you feels your horns, tracing their shape with your fingers. You jump up and race to the mirror, lamenting as you examine your reflection. Your cock has retreated into your body, turned off by your human distress. You can see the lump in your groin where the rod and balls are hiding, but its covered except for a slit, like a dolphin. Your eyes have completely morphed into that of a demon's, the pupils slitted and the iris glowing red. Your horns are a jet black color.
But your transformation isn't complete, you can tell. Your skin remains the same color, and you don't have the pointed teeth and elongated ears. Plus, no wings. You felt your cock throb inside its pouch at the idea of spreading those dark bat like wings and flying over the city, looking for pray. You shake your head, sitting down on your bed. You are determined not to give in again.
