Samantha knew she had done it again as she fidgeted with the restraints keeping her arms high above her head. She had a knack for singing up for experiments like this, even though she knew she was going to hate every second of it. Those thoughts quickly left her mind as the mechanical hands placed a bullet vibe deep into her bellybutton. Wasting no time in activating it, sending tickling sensations through her tummy and causing her to bite her lip as it was taped into place. She maybe could have held out if it was just the vibrator but seconds later the rest of the hands descended. Her laughter quickly filled the room as she thrashed with what little wiggle room she had. A voice coming from the speaker behind her, reminding her just how doomed she really was as she shook her head in desperate cackles against the merciless ticklish attention.
