Cat and Andrews 50 shades of grey

“lets get 50 shades of grey” Cat suggested as a tease to her boyfriend. “it will be good for a laugh”.
Andrew thought about it, not sure what to think, but in the end agreeing, “ok might be fun”. Cat had already told him she had started to read the book but couldn't abide by the writing.
They went on to have a coffee together at one of Cat's local coffee shops. Choosing a booth so they could sit together, their legs touching, a hand in each others lap.
—————
To Andrew, Cat seemed to now all the local baristas and waiting staff near by. It is one of the things he likes about her, her easy, kind manner. She would take the time to talk to anyone, not judging them, listening to them and people seemed to be taken with her.
After they finished the coffee, the waitress cleared the cups and made a comment to Cathy about catching up, hinting at wanting to know about what was happening with Cat's new beau.
They left the coffee shop, dodging intermittent showers, looking in shops. Just enjoying each others company.
Cat asked Andrew to turn the TV on and get the videos ready while she would whip up a light supper.
They watched the first video together while eating their meal sitting on the couch. When the video was over, Cat made tea while Andrew put 50 shades of grey on. They cuddled together on the couch and almost immediately they began to make fun of the dialogue of the movie. The fact that the movie was so bad, made it bearable as they laughed at it. When the movie got to the scene where Christian and Annabelle started to negotiate their contract, Cat surprised Andrew by saying, "we should write our own master slave contract".
"Really? You want to write our own slave contract" Andrew asked incredulously. He was wondering if he was being set up, even though the idea did turn him on.
"Why not, it might be fun" Cat teased." Wouldn't you like your own personal sex slave?"
"Ok, so do you ever want to be the mistress, or just the slave?" He asked, deciding to play along with the game. After all he had nothing to loose and it would be fun. The image of Cat on her knees, sitting demurely, her hands tied behind her back awaiting any order from him, no matter how debauched was so vivid, he would be happy to find an agreement of some sort to see it in real life.
Cat thought about it, and said she would probably prefer to be the slave most of the time but was scared to loose total control. After all, she hadn't known Andrew that long. Could she really trust him? Could she surrender total control to him? If he tied her up, he could gag her and do anything to her. He could be a total fruitcake. Somehow the idea turned her on more.
"Well how about I'm the master ninety-five percent of the time and your the slave five percent of the time? He suggested.
Cat seemed to think she had to negotiate. " how about ninety ten?"
"Ok, sounds reasonable" Andrew said while reaching for his iPad. He opened an app and started typing.
Sexual Contract between Cat XXXXXX and Andrew XXXXXXX dated 13 June 2015.

This a Sub/Dom agreement between Andrew and Cat, to formalise a BDSM relationship between them.

"Ooh, making it formal all ready" Cat joked. "Well if something is worth doing, it's worth doing well" Andrew replied.
They continued writing things down, getting ideas while still watching "50 shades of Grey". When the scene where anal fisting came up, Andrew asked " what about anal fisting?". Cat's reply made Andrew laugh, "only if you really want it done to you".So no anal fisting went into the contract.
After the video ended, Andrew grabbed Cat and pulled her over his knees. He lifted her top, exposing her tights covered rear. He admired her bum. He loved to look at it normally and the thought of what he was about to do lifted his excitement higher.
He told her to lift her bum, then he pulled down her tights and pantys. Gently he placed his hand on one of Cat's beautiful round bum cheeks. Then slowly started to pat them. It only took thirty seconds before Cat started to squirm on Andrew's lap. Suddenly there was a loud "crack". Cat in shock stiffened, the spanking taking her by surprise. Immediately Andrew began to pat her cheek again, relieving the sting, making Cat squirm again. Andrew repeated this several times, alternating cheeks. He watched her cheeks start to turn red, marvelling how his hand print was vivid before slowly fading. Each time Cat's squirming increased. When she felt Andrew's hand lift from her bum she would tense, so Andrew turned it into a game. He would lift his hand and watch her stiffen in his lap, then return to patting her, repeating this several times before spanking her. Sometimes giving several quick swats. Or alternating cheeks in quick succession.
Andrew found this incredibly erotic making him hard. He was sure Cat could feel his erection sticking into her stomach.
Cat's breathing had increased, showing Andrew that she was getting more and more aroused. He continued the spanking, with the pats moving lower until he was gently rubbing between her legs, feeling her wetness.
He stopped the assault on her ass, happy with the red glow it now had. " get off my lap and get on your knees" he barked at cat. She hurried to obey her new master, his order turning her on even more. She watched as Andrew unzipped his pants and took out his hard cock. He pushed it between her lips, she opened her mouth and allowed him to use her. Andrew put his hands firmly on her each side of her head, showing her who was the master but still being gentile. He cared for Cat a great deal, and even though he enjoyed giving her some pain, he didn't want to hurt her.
He withdrew his cock and told her to stand, then grabbing her by the hips he spun her around, pushed her by the shoulders forcing her down before plunging his cock into her wet pussy. He marvelled at how wet she was. The feeling of her pussy feeling glorious. The sounds Cat was making driving him wild, making him want her even more.
Pulling out of her, he sat on the couch, making Cat straddle his lap. Gently she guided him inside her, slowly pushing him further and further inside until their pubic bones met. She slowly started to grind against him, Andrew watching the look of concentration coming on to her face, eyes closed. He loved watching her expressions while they made love.
After a while Cat with great difficulty, raised the issue about getting the couch wet if she squirted. This gave an idea to Andrew, one that always turned him on, but one he had never tried. He grabbed Cat by the hips, leant forward and stood up, for a glorious second he stayed inside her before slipping out, much to his disappointment.
Letting Cat gently to the floor, they went to the bedroom to continue their lovemaking.
