It was the night of the second Thursday of the month and Sheldon Cooper, PhD, etc., etc. walked down the apartment house hallway to the door of Amy Farrah Fowler. She had extorted a verbal contract out of him in which he agreed he would be her boyfriend and that she could reciprocate by calling herself his girlfriend and that they would have monthly dates. Within a few days, that verbal commitment was put into writing and they signed it. That evening was the day and the time agreed upon so he was forced to call on her at her apartment.
"What a nuisance," the lanky scientist muttered to himself. "What a colossal waste of my valuable time. I could be watching the Star Wars special or playing with my electric trains or positively proving String Theory or any number of other useful things. Instead, I am compelled to call on this female person just because of some stupid agreement I was forced to sign."
When he reached her door, he ignored the doorbell available and knocked three times. "Amy," he said. This ritual was repeated two times before the door was opened by an angular appearing dark-haired woman with a rather long face. She was wearing her usual flannel shirt with a cardigan and a tweed skirt.
"Hello, Sheldon," she said and tried to reach out to embrace him.
He was too quick for her and got his hands on her arms to block her advance. When Amy leaned forward, hoping to kiss his mouth, Sheldon quickly turned his face and her lips barely grazed his cheek. Forced to settle for that platonic greeting, she took his arm and led him into her front room.
"Sit down," she said, pointing to the sofa. "I'll just be a minute."
Sheldon sat on the place he had claimed as his own but, before he could relax, two people - whether they were men or women he never knew - dressed as Ninjas sprang from behind the sofa. Before he was able to put up any kind of resistance, they had tied his feet together and shackled his hands behind his back. Gently, all things considered, the two assailants laid him on his back on the carpeted floor and placed a pillow under his head. True to her word, Amy returned just a minute after leaving. She smiled at the sight; her plan was working perfectly.
"Amy Farrah Fowler, what is going on?" the indignant Sheldon asked. "Why has my brilliant person just been assaulted?"
"You'll see." Amy paid off her hirelings, escorted them to the door and locked it securely after them before returning to her bedroom.
When she returned to her indignant reclining boyfriend, Amy was wearing a transparent teddy she had bought for that night. He should have known the answer from what she was wearing but Sheldon asked her the same question and got the same answer. However, this time she demonstrated the reason her boyfriend was lying helpless on her carpet when she knelt beside him and started to unfasten his belt.
"What are you doing!" her captive squawked, although it should have been quite obvious.
This time, she answered him. "This relationship is moving too slowly so I'm going to speed it up tonight."
Sheldon continued his struggles but they were to no avail. His hands and feet were immobilized and all he could do was try to twist his body away from her but Amy had a firm grip on his belt. With that unbuckled, she unbuttoned the waist of his pants, pulled down the zipper of his fly and placed the fingers of both hands where they were ready to pull down everything he was wearing below the waist. Sheldon continued to struggle but his efforts only helped Amy carry out her plan rather than hindered her. She timed his movements and pulled his pants and jockey shorts down around his skinny ass when most of his weight was on one hip.
Her boyfriend was naked between his knees and his waist and she was even more scantily clad. Amy gazed on what she had lusted over for most of the last three years. Being completely flaccid and flopping against Sheldon's thigh, his cock didn't look like much but she had studied what to do about that problem. Placing her hands on his bony hips to hold him in place, she leaned over him and drew his cock into her mouth, holding it in place with her lips.
"Amy Farrah Fowler, that's your mouth!" Sheldon protested.
Having a PhD in Biology, she knew what and where a person's mouth was. Recently, Amy had also been an ardent reader of The Illustrated Guide to Sex and knew how to turn a soft cock, such as Sheldon's, into a rampant erection. With her mouth pressed against his pubic hair, she stroked and teased the soft bit of flesh with her tongue. Amy was elated when, after no more than a few seconds of this kind of treatment, she could feel it becoming harder and starting to fill her mouth.
Everything that was happening to him that evening was new to Sheldon, who knew almost everything about a few subjects but virtually nothing about sex. He was aware a man's penis was used during sexual intercourse - coitus he would have called it - but he had always believed a woman had a special place between her legs that she used for that purpose. Under no circumstances could he have imagined a woman using her mouth as a receptacle for a sex act.
Amy was a virgin too and had been as ignorant about sex as her boyfriend but that was before she learned a great deal in her recent studies. She knew it was possible for a woman to be upright on top of a man, a position the book called The Cowgirl, and take his cock into her pussy. There had even been a drawing of a man and a woman using that position and she intended to emulate the woman once Sheldon was ready. Amy continued stroking his cock between her lips and fondling it with her tongue, feeling it growing bigger and harder until she believed it was ready for her purposes.
She had been kneeling beside him but Amy swung her left foot over Sheldon's legs so she was straddling him. She gently held his erect cock in one hand and walked on her knees until her pussy, which had been lubricating since seeing her boyfriend lying on the floor, was directly over its head. Amy reached down between her thighs to spread her lips as had been illustrated and described in the book. Moving slowly, she lowered her body until contact was made and rubbed the end of his cock in her wetness. Everything was ready so she slowly lowered her body until she felt something impeding her progress.
She had expected this and was prepared to deal with it. Still holding Sheldon's stiff cock in her hand, she thrust her body down. There was a feeling of tearing, as she felt the head of Sheldon's cock wedge into her yearning pussy and a small amount of pain but the pleasure of finally getting what she had lusted after for so long more than made up for it. After the initial sensation, she waited a few seconds before lowering her body farther. There was no pain at all, nothing but a mellow feeling of pleasure as the head of his cock wedged into her pussy.
For Sheldon, there was just panic at the strange and frightening sensations that were starting to fill his body. "What are you doing to me, Amy Farrah Fowler?" he asked her and he really didn't know.
She answered his question. "Well, Sheldon, I guess you have a right to know. I'm fucking you. I have your cock in my pussy and, in a few seconds, I will start to move up and down and keep doing that until I have a climax. You should have one too. How does it feel to you so far?"
