The tentecles experiment is an experiment where they are trying to figure out if tentecles give more orgasms than humans do. I am the girl they are doing the experiments on.

Ellie sat in the chair her legs spread with her arms and legs tied. She squirmed trying to get out of the straps.

ugh

The chair beneath the girl shuddered slightly as a machine hummed to life.

An unseen speaker within the chair said in a male's cheerful baritone, "Please state your name."

It paused for her response, then continued,
"Hello, and welcome to the CLBR model # 1314. Or Calibur, for your convenience! Calibur is a specially equipped state-of-the-art chair designed for testing and examining willing (or unwilling) female subjects such as yourself!"

Several tentacles made of metal emerged from beneath the chair. One slid down the neckline of her blouse and pulled the material up, exposing her bra. One tentacle stroked the sides and flats of her stomach, while the other rubbed underneath her young breasts.

The tentacles occasionally released small charges of electricity against the tender flesh, which was caused some pain, but brought a great deal more pleasure.
