Hm.

I wonder if their breasts could be utilized for MORE than just 'fun bags' when they get intimate.





Could see (as a possibility) them being able to turn one person with a touch, by using the needles to inject mass amounts of nanites and inorganic materials into the human's system.







They would possibly swell and get zaftig as their bodies store enough materials for the upcoming conversion.







Once done, they'd be 'flat' until they ate enough inorganic materials to fill out and repeat the process.





They'd STILL have the other conversion options, including the 'dildo vac', but this could be used if the Sister-to-be is hesitant to go out to the trucks.





This could be a more INTIMATE Conversion. Granted, the human would have to be in the right mindset to watch as they change over into thier gynoid's Sister...







Thoughts?
