Samantha felt the tight walls pull and suck against her miniature body, the strong warm scent clinging to her body as she was pushed into and out of her mistress like a toy.  She felt so aroused being used in such a way and tried to rub her crotch against the squelching wall by arching back as the motion built up and she was pushed deeper, her entire body now coated in Sarah's slimy inner fluids.  It felt so good, the degrading, humiliation arousing her so much that she couldn't help but lick and rub whatever she was thrust against, her hair soaking wet with sexual juice.<br/>'Oh mistress....please, use me harder...I want you so badly,thrust me in deep and fast, I beg of you mistress Sarah.'  Samantha's thoughts entered Sarah's mind as she was used.<br/><br/>Natasha continued to watch, one hand reaching under her lab coat and gently stroking her own pussy, which had become wet from watching Sarah use her sister like this.  She never knew she was into voyerism until now and tried to bite her lower lip as if it would stop her getting further aroused.  All the while, her gaze was shifting between the computer screen and Sarah...tiny nano camera's recording her actions while the helmet sensed Sarah's brain activity...a few patterned pinpricks on the screen showing where Samantha was communicating with Sarah.<br/>"Just...keep...going"  Natasha spoke, her face getting a little redder as she started to push her fingers inside herself, feeling her heart rate increase as she felt her urge to climax increasing and begun to suckle on the tip of her thumb, unable to resist what she was doing right now while at the same time trying to reassure herself that this was just an experiment.<br/><br/>Karia giggled.<br/>"You're kinda defensive for a computer AI."  She mentioned as they approached the research lab.  "Well, we're here!"  She spoke, pointing out the lab just ahead.  "Now you'll be able to tell us what happened."  Karia smiled, hoping it was more interesting than hanging around with the old man nagging her all day on how to treat her shrunken toy...they were criminals after all...not national heroes, she didn't see why she had to treat them with any dignity or respect at all.
