Assimilate her now

Wordlessly you make your way to Jenny. Mechanical tendrils emerge from between the segments of your armored plates, their metallic needles snaking through the air toward your friend. The portal engine surges with hellish energy in preparation for what is to come, making your entire body smolder from the heat.

Your hands start to explore your chest, the nearly molten metal now soft and pliable and easily giving way to your clawed fingers before trailing down below your abdomen. The feeling of your pussy is divine as you find your g-spot in the convulsing roof underneath your clit.

The tendrils easily pierce Jenny's skin, and you watch them crawl underneath the surface of her arms and legs, leaving a trail of melting skin that falls off her like slag to reveal a metallic frame replacing her bones. You're too caught up in your pleasure to register the tossing of her blindfolded head as she tries to make sense of what is happening. She's not in pain, rather the opposite, you note as you process the electrical signals racing through her spine. Through the connection, you share some of your sensory feed to send her over the edge again and again. You don't stop until her sex drips with translucent juices and labia quivers, seeming to beg for mercy.

The conversion of the vertebrae is slower than the rest of her body. The cold and calculating machine part of you is already making adjustments for the future

The others are looking on with horror as Jenny becomes little more than a robotic skeleton with rudimentary fiber muscles connecting the metal limbs with the torso. But they don't have time to worry about her as they're set upon by your blue-skinned sister. Her hands, mouth, and tail each set to work on one of the men. You can sense her feeding on the quartet's life essence and physically see them wasting away as she indulges in her ravenous hunger. She is almost frightening.

Your tendrils only seem to multiply as new ones emerge and coil around their prey until nothing of Jenny is visible. Your tear your friend from her shackles, hearing the stone crack as the hinges break before becoming more raw materials from her transformation. Soon all that's left of Jenny is her brain trapped inside its alloyed husk of hellsteel. Underneath the tendrils, you can feel the machines slowly replacing her organs, the replacements whirring into standby mode, just waiting for a connection. Fulfill the Succubus Queen's agenda. You shudder, a dark puddle forming between your feet, as you plunge the needles into her brain and inject it with nanites.

It's less than you first imagined as the nanites feed you half-faded memories of Jenny's over two decades of life. You shunt most of it into a backup storage unit, but not before you catch a few glimpses of a few of her dirty secrets and barely contain a laugh. She wanted this! And here you had come to save her!

You retract all but one of the tendrils back into your body after confirming her soul is still intact and unharmed. Although now thoroughly corrupted after bathing in the infernal energies you poured into her. The pistons in her legs hiss as the auto stabilizers adjusts themselves to keep the body upright as she lands on her spiked heels. She still lacks a shell, her machine's guts on full display, but that will come when you upload her core programming and reboot her. A mindless drone wouldn't require much, not that you would do such a thing to your dear friend, not yet anyway. While an infiltrator unit meant to maintain the appearance and lifestyle of humans requires something far more complex.
