"What did you do to me?!" I yelled. I stomped towards her, my new weight and strength making the floor underneath her shake. Her breasts and ass jiggled from the vibrations enticingly. She moved on the ground, spreading her legs, and turning to face me as she slowly shuffled back away from me. She bit her lip like she was turned on by my sudden display of aggression. "I don't think so." I said, "You aren't running from me, not until I get answers." I pounced on her. My new pincer arms gripped her just above the waist on instinct, and my right hand gripped her by the throat. "Now tell me!" I leaned in real close and growled into her face, "What did you do to me?"
"Isn't it obvious?" she said in a low hushed breath. Her legs wrapped around my waist and pulled me in close. Her clawed hands reached in between us, "I needed a mate, the perfect breeder to fill me to the brim with his cum until I swell with it." Her hands gripped my new sheath around my cock causing me to moan. "I could of had any monster I wanted down here in the pit but I wanted to create my own." My cock quickly began to harden under her attention. My grip on her throat loosened a bit as my breath deepened, trying to control the fire she was throwing fuel on. My pincers seemed to run on instinct though and gripped her hips tighter. I looked away from her bright purple eyes down to my raging cock. It had changed in shape. It looked like a massive red rocket. The tip was as wide as a two liter, and was pushing out. She guided my cock to her cunt and let me grow inside her. I gasped as I felt her warm wet walls part around me. Her pussy stretched more and more as I continued to get hard and push into her.
Both of us were panting and grunting as we finally joined together. Then the dam on my self control broke and my hips became a blur of motion. My clawed hands gripped the cave floor by her head, while my pincers held her place for the destructive onslaught that my now fully hard cock was giving her cunt. Moans, roars, and the sounds of her claws tearing the ground filled the air. I felt my balls swelling between my legs, and the sound they made as they slapped her ass was something that would burn in my memory forever. I needed to bottom out in her cunt, needed to fill her with cum. But my huge knot was preventing that. So using my pincers I began pulling her into me as I just kept the pressure on. Using all my weight and strength to shove myself inside. Her hands gripped my shoulders. Her claws dug into me as she cried out. Her tail whipped up and shoved into my ass piercing my prostate again. I roared as finally my knot slipped into her pussy, locking us together. My balls swelled more before they began pumping gallons of cum into the creature clinging to me. My eyes saw stars, as the pleasure tore through me.
I could feel her venom working in me again. My cock swelling in size inside her, my balls never seeming to empty of cum as her belly ballooned outward. She had gone limp beneath me, her own body wracking her with orgasm after orgasm. So I took the moment to finally suckle on those massive breasts that had been teasing me since I saw her. I licked each nipple with my long tongue in slow strokes, then sucked them hard in between my teeth. Mhhmmm maybe being a monster wasn't gonna be so bad after all.
