Though her husband was on top doing his best to satisfy her, her thoughts were elsewhere. She was fantasizing that a large man, certainly not fat, but very, very large and muscular man was on top of her. Giving her the fucking of her life. She could just barely grab him around his back, feel the tight muscles under her clutching finger tips. Sometimes she would imagine holding his thick neck, or grabbing his ass. Luckily he was propping himself up a bit on his arms or he would probably crush her. Her legs were stretched open to their limit accepting his hips, thrusting into her. And his amazingly thick, long, cock was buried deep into her. Filling her up. She let him take her any way he wanted. She kept focusing on this image until it felt it was very real.
It's the only way she can get off now. She couldn't orgasm any longer with the love making of her husband. It just wasn't intense enough, erotic, sexy, not even close to doing the job. She would lie there and flip through half a dozen or more images in her mind, until she found the one that would work for her. Sometimes an old boyfriend would do it, or someone from work, or someone she saw on TV or the internet. But recently it was the big man that totally dominated her fantasies, got her over the edge to orgasm, in the amazing ways.
She had to give it to her husband though, he usually works at it until she came first. Which can take a while at times. She would plead, "Warm me up honey.", but usually he just went right at it. It was his own fault that it took so long really. So she would drift away into fantasy and orgasm in a dream world. After she orgasmed, she could feel his frenzied cock stabbing inside of her, then a shuddering and he would cum inside her. He would lie on top of her for a moment, before rolling over on his side, and then before too long she could hear him snoring. There were times she would have to do her herself after he fell asleep, or bring herself a second time, to get the edge off. She would bring up the large man into her imagination and bring herself. She wondered a little about whether her husband noticed her bouncing and shuddering next to him, but it wasn't enough of a worry, to keep her from doing it. Then she would be able to sleep too.
The large man, the big man. She kept bringing his image back up, trying to make him, more and more real. Sometimes she think about him at work. Feeling his large hands around her ankles as he lifted her butt up and thrusted himself into her. He began to fill her every hour and often her dreams. His image in her mind doing her would often get her so worked up she would have to go to the bathroom and rub my clit until she came. She look at her face in the mirror afterward and hope no one notices how red she was before going back to her desk. With her pale skin it was hard to hide.
If she could convince her husband to let her get on top, her thoughts could really run free. She was riding the large man's enormous cock for her own pleasure. Controlling the speed and the depth. It is so, so deep inside of her, filling her whole body. Her hands were on his nice wide hard chest. Feeling his hair under her palms. It made a good platform to stabilize herself as she slid up and down. It doesn't take too long to cum when she thinks of it. And she screams and thrashes about with the pleasure of it. Her husband goes along with it, though it's not enough for him to cum. Afterwards she tells him "Take me from behind?" She wants to cum again, using a new image of HIM holding her tiny little bottom and doing her doggy style. She would cum again at the thought of it.
Things went on like this for quite a while. Her reliance on the fantasies becoming more and more important to having intense sex. She could easily draw a picture of her large, huge man, his face his body, his cock.
Then one day it happened. She saw him. Saw the big man walking along the street towards her. He was impossible to miss, as he towered over all of the people around him. As he passed she almost fainted. She hesitated for a second, then knew she had to follow him. He walked at a fairly steady pace, only stopping at cross walks waiting for the lights to change. Then he went into a coffee chop. She looked at him through the window, standing in line waiting for his order to be taken. Do I go in? Or wait. She eventually decide the best thing to do is wait for him to come out. It wasn't too long he came out and started walking further down the street, and then eventually several blocks away opening a door to an office complex.
He went in, and walked over to the elevator bank. She cautiously went in after him, but he was gone in the elevator by the time she got there. She looked at the floor indicators and saw it stopped on the sixth floor. Now she knew where he worked.
The next week or so she waited across the street from the coffee shop, and sure enough he would show up around the same time, grab a coffee and the go to the building where he worked.
One day she called her husband and told him she would be working late and to make his own dinner, she would be home as soon as she could. Then she staked out in front of the big man's office and waited for him to come out. He came out and walked in the direction of the coffee shop but kept going, eventually going down stairs into the subway. She rapidly ran after him and was just able to keep up with him through the ticket gates and numerous stairs to the subway platform. Luckily, he was big and easy to see above the crowd. But she was tiny and when the crowds became thick she couldn't see over their heads. But somehow she was able to do it, and get on the train he boarded. They rode for quite a long time, then she saw him get up and she did as well, trying to stay as hidden as possible. Then he got off the train, walk down the platform, up the stairs to the surface. She followed him a few more blocks and he went into an apartment building. Now she knew where he lived. And she really wanted him more than ever. She was obsessed.
She started hanging out inside the coffee shop as many mornings as she could. She would always try to get there before him. Get a coffee. Nurse it in a corner table and then hide as well as she could when he was inside, but still occasionally taking peeks at him when she could. She tried to burn in his image into her mind, so when she was alone or with her husband making love she could bring it up in the most realistic way possible.
One day she is sitting at a table watching him order and get his coffee. As he was leaving she didn't turn away quite fast enough and he saw her looking his direction. His face changed slightly when he saw her. Looked puzzled, curious, shocked. She turned quickly and looked at her phone. Then she saw his backside, as he left the shop.
She didn't go back for several days, but the pull of seeing him was too great and she eventually returned. She was much more cautious, and tried to make sure he didn't see her looking at him, or see her face.
But about a week later she was looking down at her phone trying to be invisible when she sensed someone was close by, right next to her.
"Hey, do you mind if I share the table with you."
The shop was always crowded, so this didn't seem out of the ordinary. She had been asked this question before. But when she looked up to see who was there. It was HIM. It was hard to get the words out, she was so shocked.
