The Double Pleasure Experiment

Author's Note: I decided to take my chances and post chapter 2 here. Please heed the warnings from the previous chapter. This is not for the easily offended when it comes to PWP.

Chapter Two: The Preparation

It was finally the weekend. Penny was so excited and was looking forward to tonight's sexy activities. Sheldon spent most of his free nights preparing for the sanitation process before the night's festivities.

After having dinner by himself, Sheldon went over to Penny's place. He was carting a brown bag filled with various items and had an overnight bag slung over his shoulder.

"Knock, Knock, Knock, Penny! Knock, Knock, Knock, Penny! Knock, Knock, Knock, Penny!"

The door opened and his cheesecake scented goddess opened the door wearing a green silk robe. He could tell she was naked underneath as the silk clung to every curve and was belted low with a wide slit in front. It revealed a deep crease sans bra. Also, her nipples were extremely tight and poking through the material of the robe.

"Hi Sheldon!"

"Hello Penny. That robe is most flattering to your eye color."

"Thank you."

Holding the brown bag to the side, Sheldon leans over and kissed her soundly.

"Ok Penny. Are you ready to be sanitized for our anal encounter?"

"Jeez, Sheldon. Could you make it sound more clinical and sterile?"

"My apologies, Penny. To put it crudely, are you ready for some hot anal lovin'? "

Penny laughed out loud and grabbed Sheldon's hand.

"Come on Whack-a-Doodle. Let's go to the bathroom."

Once inside the bathroom, Sheldon placed his brown bag on the closed toilet seat. He removed all of his clothes except for his boxers and pulled out a water bulb and small plastic water pan from the bag. He went to the sink and waited for the water to warm up. Once he was satisfied with the water temperature, he filled the small pan with water. He then put on a pair of latex gloves.

"Ok Penny. Please remove your robe and stand in the tub. It is time to sanitize your anal cavity."

Penny removed her robe. She was breathtaking in her nudity. Sheldon's mouth watered, but he was focused on the task at hand.

"Face away from me and lean your hands against the shower wall. And spread your legs a bit. The water is warm, but you will feel a slight pressure as the water fills the cavity. Relax and take steady breaths throughout the process."

Penny was getting rather excited by the whole process. Who knew her Moonpie was so knowledgeable in preparing for anal sex?

Sheldon took the bulb and filled it with water. He then placed his fingers at her opening and spread Penny's butt cheeks apart. He inserted the thin opening of the water bulb into her sphincter. Then he squeezed the bulb. Penny felt the water filling her ass.

"Very good. Now I need you to expel the water from your anal cavity. Then I will repeat the process a few more times. In addition, your bathtub will require a proper cleaning with a mild cleaning solution. There are minute fecal deposits trapped within the miniscule cracks in the fiberglass frame."

"You excel at cleaning porous surfaces Sheldon. Maybe you should clean it yourself."

She said this with a smirk because he couldn't see as her back was turned to him.

"That is an excellent idea Penny." I shall see to the thorough disinfecting of the tub in the morning."

"You do that sweetie while I sleep in."

Sheldon repeated the process three more times. Penny was a little embarrased by the whole procedure but didn't say anything because Sheldon was being very clinical about the whole thing.

"All right. I need to wash and rinse off your lower body. When you are finished, we are going to prepare your anus for my penis. I don't want to hurt you during penetration. Now I am going to lubricate your anal passage and insert a small butt plug to get you ready."

Penny was beyond shocked. She had no idea there was a freaky side to her Moonpie. Where did he get the sex toys? Penny rinsed herself off and grinned in anticipation.

Sheldon rinsed off the butt plug with soap and water in the sink. He dried it off with a clean towel and pulled out some lube from the bag. He put some lube on one gloved finger and turned towards Penny in the shower.

"Now I am going to prepare your sphincter with my fingers then insert the plug inside. Take some deep breaths and relax for me."

He put his lubed finger inside and started to push in and out gently.

"Please turn around Penny and brace yourself."

She was so aroused and wondered what he was going to do next.

Sheldon took his unlubed finger and used it to spread her lower lips apart. He licked up her crease then placed his tongue on her clitoris. Penny moaned and had to brace her hands on the wall behind her. The tender assault on her clit along with Sheldon's fingers in her butt was intensely pleasurable. Then he took the hand that was spreading her open and moved it to her vagina. Two fingers went in and proceeded to pleasure her front in time to the finger in her behind. He was holding the plug in the other fingers that weren't inside her pussy.

Penny was in heaven. Sheldon's fingers and tongue were blowing her mind. His fingers in both holes and the flicking of his tongue was too much.

"Sheldon! I'm cumming! Fuck! Oh, yes! Yes!"

She came in an explosion that rocketed through her entire body. He slowly eased his fingers from her vagina, but kept his other finger in her anus.

"Very nice, Penny. I think you are now ready for the butt plug. I'm going to put it inside you then we are going to take a bath together to prepare for coitus."

Sheldon took the butt plug and lubed it up. He added more lube to his finger and put it inside her anus again. After filling her hole with lube, he gently eased the plug into Penny's ass. It was a little uncomfortable, but the plug started to settle in. Her anus felt full and she clenched her cheeks to keep the plug from falling out.

"How do you feel?"

"I feel full, but it's ok."

"Excellent. Now we are going to take a shower then move to the bedroom. I trust you changed your bedsheets?"

""Yes, Moonpie."

"Penny, only my Meemaw calls me that."

"Considering that you are about to put your penis in my ass, I think you should give me some leeway."

"Duly noted."
