Misaka's Experiment #2 (Pixiv Fanbox)

Dr. Yamanako stood and nodded at Bethany, who bowed slightly in acknowledgement and led Kaori into the small side area containing the gyno chair. It was quite menacing...with straps for all four limbs as well as shoulder pads to keep the occupant from any movement at all. Bethany deftly helped Kaori into the seat and quickly restrained her before stepping back and donning her own...medical instrumentation. A large red strap-on dildo. Kaori’s eyes widened as she looked at her momm...no...the doctor...for help.

Dr. Yamanako paid her no attention though, as she squirted a thick oily cream into her hand and gently stroked Bethany’s strapon cock with it. The fourteen year old nurse squeezed her eyes shut and struggled to maintain her composure as the good doctor gave her a brisk hand job. With normal strapons, stimulation like this would do nothing for the wearer. However, The Facility has only the most highly technological and sophisticated apparatuses. This strapon had a special dildo attachment on the inside that protruded inside Bethany’s pussy, stimulating her at the same level that the outward pointed dick did. Her breathing intensified as Dr. Yamanako jacked her off harder, then abruptly stopped.

She strode forward and grabbed something off the table behind the seat as Bethany stood in front of the seat and gently probed the entrance to Kaori’s puffy cunt. “Now, what Nurse Bethany here is going to do is to coat your insides with that special cream that will help strengthen your vaginal muscles. This is necessary to keep you tight and so that your vaginal secretions smell like strawberries.”

“But I’m still tight! And when you lick me at night you tell me I taste like strawberries and cream!!” Kaori exclaimed.

The doctor frowned. (and Bethany gave her an amused look) “Nurse, the patient seems to be uncooperative. Please use the gag to restrain her.”

Bethany smirked to herself as she leaned over and got the large tube gag and rudely strapped it around Kaori’s head. “Now this dildo gag is special. It can sense when you orgasm, but it also has a built in timer,” Bethany patiently told Kaori as she took the dildo attachment from the doctor. “If you can maintain your composure and keep from orgasming for five minutes while I am administering the cream to your cunt, then it will reward you with a nice hot dose of semen. Are we clear?” And without even waiting for an answer she gently but firmly inserted it into the gag opening.

Kaori watched with wide eyes as Bethany positioned herself at her tight little entrance. She knew that Bethany was considered the sweet older sister to her friend Alice, but she’d heard stories about her. While Alice was a submissive for the most part, Bethany was considered a “switch”. She could be a sweet young submissive ready to play the gentle cutie...but with the flick of a switch she could put on the latex and makeup and become the brutal domme capable of whipping you into submission and making you her personal plaything. She was the definition of “angel on the streets, demon in the sheets”.

And judging from the intense look in Bethany’s eyes, she was about to meet that demon.
