Two for One After over indulging, Jen had complained to her sister that she had a few extra pounds on her hips. In truth, this was more in the mind. Both girls had tremendous figures. Both were light skinned and had long blonde hair running down their long backs. Both girls were 5'9'' bare foot, and had a steady weight of around 128 lbs. They both enjoyed cross country running, and had nicely toned physiques, with a small degree of muscularity. After days of complaining about the excess weight, Jen convinced Tara to come to the local gym with her. Tara agreed as usual. The first few sessions saw the girls run, bike and step in a bid to tone up and lose the imaginary pounds. But after several visits, and being more comfortable in the gym environment, Jen suggested that they try some of the weights. These were normally hogged by sweaty guys, but for some reason, the gym was quiet on this given day. Tara joked as she lay down on the bench. Jen took some of the plates off, and handed her the bar. Tara squealed and laughed as she strained and managed a weak couple of reps. Jen helped her put the bar back on the stand." How much was that then?" asked Tara"Erm, 110 lbs" said Jen as she read off the side of the plates and did the maths in her head "Is that good?" Asked Tara Jen shrugged her shoulders. While being fit, neither girl had ever lifted weights in their life. In fact, neither had done anything slightly resembling a manual task. Tara stood up and did a mock flex. Both sisters laughed. Her arm had some definition, but the muscle was small and smooth. Jen then took to the bench. We were about to find out what the difference between the 2 girls was. Jen took the bar in her hands. She slowly pulled it to her chest with her sister perched over her, ready to help her out of she was to struggle. Jen smiled and straightened out her arms, and again, and again. She repeated the motion 10 times before resting the bar down. Tara applauded. "That was nothing" boasted Jen, "Stick me some more on there" Tara did, and loading up the bar to 130 lbs Once more, Jen took the bar and pushed out 10 reps with apparent ease." Have you been working out?" asked Tara "No, I swear" said Jen, rather shocked by her feat. Jen was the exact same built as her sister, how she was so much stronger was a complete mystery. "Go some more" said an intrigued Jen This went on several times, until Jen struggled with her tenth rep, AT 230lbs!!!!!!! "Well I am either really strong, or you are really weak" said Jen Both sisters laughed and went of to shower. The gym incident had been fun, but it was soon forgotten. It was months later when the girls were in a nightclub, when the issue was brought back up. Both girls were sat in identical black dresses is Fandango Nightclub in town. 2 big guys came over with drinks, trying their luck with the attractive blonde sisters. They got chatting, the guys boasted about their rugby victory earlier in the day. One guy proceeded to flash his large bicep to the 2 girls. "Wow, that's some muscle" said Tara, "We did weights once" she laughed ... "Cool, strong ladies huh?" mocked the big guy ... "Well, we don't know. We just lifted some weights, I have no idea if we are weak or strong" she explained." Well, how much did you bench then?" enquired the rugby player. "Hmm, I forget, I think it was about 110lbs" said Tara laughing "Wow, that's pretty impressive, you don't look that strong" he said as he examined her sleeveless arms "Ok, no need to take the piss" said a laughing Tara "No, I am serious, 110 lbs is a hell of a bench press, I know guys who struggle with that" he said Jen was pretty quiet; she was listening to all of this, and trying to think of how much she had lifted Eventually, she chipped into the conversation "So if a girl our size did, say, 230lbs, would that be good?" The guys all laughed "If someone your size did 230lbs, I would check if they had balls" said the front man "Well, do I have balls?" said a serious looking Jen The guys stopped, looking puzzled "I did 10 reps at 230lbs, I thought it was shit, but you are saying that it would be a good lift?" she asked in her naivety "Good!" exclaimed the guy, "It would be impossible" "So you're calling me a liar?" shouted Jen, suddenly losing patience with the man who was chatting her up. "Well, erm, no, but I mean, I am 6'2 190 lbs, and I only just bench more than 230lbs" said the big guy Jen had no idea what came over her, but she was furious "So you are 190lbs?" she asked The guy nodded "Right, then a girl my size shouldn't be able to do this right?" she said as she moved towards him and in one swift motion, had picked the guy up in her arms. The other guys were shocked. Some laughed, some blushed, but the big man was hoisted in the air, in Jen's arms, looking rather embarrassed Jen put down the big man and apologized The big man had seen his pride hurt, he had to respond as only a man could. He slammed his arm onto the small table. "Make fun of me huh? Easily solved" he shouted, gesturing to Jen to have him an arm wrestle. Jen had never done this before. She was almost half the size of this guy. His arm was way bigger. She should have been easy pickings for him, but for some unknown reason, she had this inner strength. They locked hands. His were sweaty, obviously a bag of nerves with the audience watching and the implications to his manhood. "Go on Andy" shouted one of the group, Andy, the big man, was stunned by the resistance being shown by Jen. Jen's arm was straight and solid, not a hint of a quiver. She had no idea how she could com Jon with such a big man, but she was doing, and easily. Jen began to push. Andy's face began to drop as so too did his arm. Jen strained and went over the top. The onlookers were disbelieving. Jen gave a big shove and slammed his hand to the table. "Fucking freak" spat Andy Jen's arm was held up by Tara as the 2 girls headed off to the bar to celebrate. As the years went by, the 2 girls remained close. They still ran cross country races, and had the odd workout, but the weights never became part of their lives. By the age of 25, both girls had grown into beautiful women. Tara had found her dream guy. Jon was a semi professional soccer player. He was slightly taller, and of average build. They were very happy together, and for the first time, something had gotten between the 2 twin sisters. Jen was happy for Tara. She was glad that she had found someone special. She even liked Jon, perhaps too much. The twins had shared an interest in most things in their lives; this seemed to extend to choice of guys. Jen sat alone one night in her 1 bedroom flat. The TV flickered but she wasn't really watching. She was thinking about Jon and Tara. Jon was a nice guy, but he had come between the 2 girls. Part of her wanted him for herself, part of her wanted him out of their lives altogether. She fell asleep with a bottle of wine in her hand, something had to give. Tara called on Wednesday morning. She was due to go away for a week with her work, but she had come round with more dramatic news. As Jen opened the door, Tara had a huge smile on her face. She did not need words; she simply flashed her left hand to her sister. Third finger along played host to a huge diamond. "Jon and I are engaged" she squealed. Jen hugged her sister. She was happy for her, but bitterly jealous. She saw Tara off to the airport, and as she drove back home, she decided that now was the time. She had to do something about the situation. She couldn't split up Jon and Tara, her sister would be broken, and if she ever found out, it would break the sisters apart. So she opted for the next best thing, she was going to get Jon for herself. She turned off the motorway early, heading for the house shared by Jon and Tara. She did her lipstick in the mirror while stopped momentarily at the traffic lights. She pulled up outside the house. She breathed heavy. This was big, once she did this; there would be no going back. Her plan was to seduce Jon into sex by fooling him into thinking it was Tara. She would then blackmail him into making it regular or she would tell her sister that he had instigated sex. She was about to leave the car when she glanced at her left hand. No engagement ring! She hadn't thought this through, she would easily be spotted at the impostor. She drove off to perfect her plan, tomorrow would be the big day. That night Jen made sure of every fine detail. She bought an engagement ring identical to Tara's. She sprayed herself with Tara's favourite perfume. Despite them being twins, Jen knew of a few tiny differences that only the girls could spot. She attended to each of these until she really was the same as Tara, exactly the same. She got a taxi to Jon's the next morning. Her car would be the giveaway. Jon was in the upstairs window typing on his PC. He worked from home when not out training. Jen got out the spare keys and let herself in. "Honey, Jon?" she called Jon was shocked to see her"But, Milan?" he asked "I was missing you so much, I had to come back" lied Jen, .Jen and Jon kissed in the hallway, Jen was in heaven in the arms of her sisters husband. "Lets go to bed" said Jen in her best sultry voice. Jon let go of Jen. "Erm, can we later?" asked Jon. Missing Tara, Jon had woken hours before and jerked himself off and so wasn't really yup for sex right now. This was not what Jen wanted to hear. Jen grabbed Jon "I said, I want sex, you are my fiancé, now you oblige". Jon looked shocked. Clearly this was out of character for Tara, but of course, this wasn't Tara at all. Jen advanced, Jon backed off up the stairs. As they entered the bedroom Jen pounced, She pushed Jon hard onto the bed and jumped onto him, holding him down fast. "What's got into you, stop this" said a scared Jon. Jen just smiled as she reached down and began to caress his groin. Jon didn't like this aggressiveness but as she massaged, he did begin to get hard. Jon began to struggle, he was now horny, but she didn't like the idea of his fiancé having this power in the bedroom. He was the guy, he should dictate how and when sex happened. Jen held both Jon's hands above his head to the bed. The more he struggled, the harder Jen pushed. Jon was held fast. Jen slipped off her skirt, she had no underwear on. She undid Jon's belt."Tara, please stop this" he pleaded. This fell on deaf ears. Jen removed his trousers and pants. She sat back, letting go of Jon's now pink wrists. Jon breathed heavy. Jen's hard body looked just like Tara. Jon had no reason to suspect it wasn't his fiancé, but he had never seen such strength in his partner before. "Look Tara, can we leave this, we can make love tonight" asked Jon."We" said Jen sternly, "are having sex now".With that, the struggle began again. Jon made a dash for it, but Jen's strong arms held him and pulled him back to the bed. Her legs wrapped around him and squeezed the air from him. Jon was released and fell to the bed. Jen once more jumped onto him. She held Jon down; the struggle had begun to diminish. Jen once again grabbed his erect penis. This time, to place it inside her. Jen moaned as she realized her sick dream. She rode Jon for what seemed like hours. She reached orgasm many times, Jon was being raped. After she had finished, she kissed a stunned Jon on the cheek. "I have to get back to Milan now Jon. I love you" she whispered. She was about to tell Jon that she was really Jen, but she saw his face, it was one of pure shock. She knew this would be too much to take in. Instead, she decided to go with plan.."Jon, what just happened, it was a one off, a crazy urge I always had. It will not happen again, so please, lets never mention it again" she said. Jon nodded. Jen kissed him again and left. The days passed and Jen was wracked with guilt. Tara returned home, and found Jon in a very strange mood. Jon was off sex. His male pride had been destroyed by the forceful sex that had been inflicted upon him. Tara was puzzled. She confided in her sister. Weeks went by, Tara and Jon were having sex, but it wasn't as it used to be. Jon almost seemed scared of her. Jen felt so awful about what was happening. Her moment of madness had destroyed her sisters marriage. She lay awake one night, trying to think of how she could reify the situation. Suddenly the idea hit her, she ran it over and over in her head. It was a risk, but hell, it might just work. Jen waited until Tara was out for the day, and paid Jon a visit once more, posing again as Tara. She could see that Jon was almost frightened of her. "Jon, you are starting to lose me. You are off sex, what is wrong?" Jen askedJon snarled at her, "You know exactly what is wrong. You raped me""But you liked it Jon, you were hard as a rock" replied Jen, still posing as Tara Jon sat down, and began to whimper. Jen put her arm round him. "Jon, why not admit that you loved it when I was strong?" said Jen, Jon did not reply"Don't make me force you" said Jen with menace Jon backed off. Jen suddenly got the vision of her rape into her head. She wanted it again. She grabbed Jon. Jon put his hands on her biceps to stop her, but Jen was way too strong. Jen wrestled Jon onto the floor. With one hand, she again help him down while unzipping his trousers. Jon was rock hard. Jen held herself above his erection."Now, admit it, you love it Jon" she shouted into his red face Jon was silent. Jen lowered herself onto his penis. Jon began to breathe heavy. Jen began to lift herself with her arms, almost like press ups, riding up and down on Jons hard dick. "OK OK, I like it but stop please" shouted Jon This wasn't what Jen expected. She lifted herself off him and lay beside him on the carpet. "Look Tara, your strength turns me on, but I can't cope. I am a man, I have an ego. I can't stand being at your mercy. I, I just can't do it" Jon began to cry Jen knew that what she was about to do might end in disaster. It may lead to divorce, may even send her to prison. But Jon's tears moved her so much. "Jon, what if you were stronger. And you could be the one in control, only sometimes, sometimes you became weaker" said Jen Jon looked puzzled "You know, like the incredible hulk. Under normal circumstances, you are stronger, but once in a while, I get super strong, and dominate you" said Jen Jon looked her in the eyes "That's not possible, you are stronger than me, what can I do. I ain't playing pretend games" Jen stroked his head "Jon, you are stronger than your wife" Jon was now puzzled beyond belief "Look Jon, please don't hate me. The person you see now, the person who raped you. It's me Jen, not Tara" she explained Jon was in shock. "I, I don't understand" Jen explained how she and Tara were the same except for the freak strength she possessed. It took Jon a while to take it in. He was unset at having been fooled, but the relief that his wife was not his equal strength wise was obvious on his face. The 2 chatted for what seemed like hours. Jon felt comfortable now. He told Jen how their sex was amazing, and how he had long fantasized over a strong woman taking him. But he also said how much he loved Tara and the reality comfort of being stronger than her. "Look Jon, I shall leave it with you. I don't want to split you guys up. But if you ever want some fun, and a strong woman, give me a call. It can be our secret" she said Over the next 6 months, Tara and Jon had their normal life back. Sex was resumed as normal with Jon the leader. He and Jen met up on only 3 occasions for wrestling and sex. It suited everyone. Everything was perfect, until one March night. Tara had been out of town, Jon had asked Jen over for their occasional wrestling session. Tara returned home to an empty house, and began to tidy the bedroom. She lifted up Jon's dressing gown and spotted something shiny below in the long plush carpet. She knelt down and picked it up, it was a ring, one she recognized, and it didn't belong to her. It was Jen's. Why was it here? It didn't make sense. Tara was now curious; she began to riffle through Jon's drawers. She found cuttings of female fitness models in flexing poses. It all began to add up. Over the next few weeks, Tara became surer that Jon loved strong women, and that he had slept with her own twin sister. Jen was nervous when over at the house. Was she paranoid, or had her sister committed the ultimate sin? The uncertainty was tearing her apart. Tara decided that she had to know, so set up a 'business' trip. She returned home early, just in time to see Jen arrive at the house. Her worst fears were revealed as she sneaked in. Jen was dominating her husband. Tara fled, she had not been seen. She loved Jon, and hated her sister. Through her tears, she began to plot her revenge, a plan to humiliate Jen, and win back Jon ... ... ... To be continued
