Dr Sydney is a biological researcher who is currently working on a very important research project. She's been investigating the limits of human endurance when it comes to sexual arousal. She has her current "volunteer" in her lab and she's ready to get to work, but not before making sure the subject is properly secured and all their vital signs are reading normal. These kind of experiments are meant to push the boundaries after all and she can't have her subjects going into shock or failing on her in any way.

She has her subject completely bound, wearing a special mask to control it's airflow and allow her to administer olfactory sensations. They've also been locked in chastity for a while to make sure their sensitivity is at their maximum levels. Ater securing the subject, she uses her vibrator on it's pleasure areas, making sure to monitor all the pleasure signals she's recording. She begins some extreme teasing on the subject, even inserting anal beads to increase the sensations even further.

But she's not even close to completing her experiment, which calls for her to inserted ever larger objects inside the subject's ass. She will truly test the limits as she uses one giant dildo after another, eventually having to use her own hand to fist and then her most massive dildo. Lastly, she all to drive the subject into total submission and evoke the highest stimulus response possible! From what she can tell, all indictors point to the subject being a total anal slut... Do you think you could withstand being Dr Sydney's lab rat?
