“You deserve gentleness love….there you go..just going deeper…you have plenty of space” Dr Warner said softly.

Lily groaned but her bucking pelvis showed her body was reacting well. Dr Warner’s hand retreated so his thumb would come out. He used his thumb to play with Lily’s clit and the four fingers inside playfully scratched along her shaft. Lily's legs vibrated against the straps, unable to stay still from the currents of arousal coursing through her

“I want you to accommodate any lover you choose love.” the doctor said as he vigorously manipulated the inside of her shaft. She came hard with a moan. “Just a bit longer…your channel is well primed..” Dr. Warner tucked his thumb back inside Lily’s wet canal and thrusted deeply. A small yelp escaped Lily as the twisting and thrusting continued. “AAGGHHH!!!OOWW!!!” Lily moaned wretchedly. Dr Warner was rock-hard hearing the young woman moan under the rubber dam. The mentor he trained under in dental school shoved dams and rubber blocks into his patient’s mouths and drilled them to the point of agony. The muffled sounds being covered by rubber was a pleasuring trigger.

“I need to keep going love, it’s for your own good. I see such improvement, you’re so strong!” Dr Warner said, cheering her on. He eased his hand out from Lily’s shaft, still balled into a fist for maximum stretching. He removed the gloves and threw them to the ground. A fresh pair was put on. Dr. Warner selected a hard rubber object that resembled a thick dog bone-narrow in the middle but flared at the ends. It was covered in hard rubber nodules.

“Sweetheart, you’ve been a real trooper today. Next will be a different sensory exercise so you’ll be used to different types of appliances you and your lovers may choose,” Dr Warner announced. “OOOOHHHH….”moaned Lily. “I know you’re tired but you’ve come so far, I know you can do it” Dr. Warner said as he caressed her restrained leg. His fingers traced along her puffy slick lips; with his other hand he pushed the rubber object into her hole. Lily whimpered as he pushed it deep into her shaft “AGGH!UUUHHH!!! Lily howled then muttered incoherently as her legs shook. She squirted powerfully as the spiny object ground into her shaft.

Lily continued to spasm and lose control of her functions as the doctor fucked her with the object. He stopped thrusting, but left it hanging from her shaft.He removed the bite blocks and rubber from her mouth and returned to fucking her with the object. Lily was now able to release her hysterics in the chair.

Doctor…I can’t…..Noo…..mooore!

“Hush Lily….” the doctor said as ground the tool into her vaginal wall.

Doctor..Doc..OOOOOHH!! DOCtor…..pleaseeeee!!..AHHHH!

“You’re doing fine…we said things would increasingly become more challenging”

OH MY GOOOOD!!!

“Let go Lily!

OH MY GOOOOAAA-

Lily blacked out. Dr Warner wiggled the object out of her shaft which squelched and twitched for some time. The doctor washed her privates gently so as not to aggravate her overstimulated genitalia. He pressed a button, closing the legs on the chair. He covered his patient in warm blankets leaving only her face exposed. He applied an oxygen mask to her face. He left the operatory to watch Lily come around from the comfort of his office.
