Sophie was a troublemaker. She was 22 years old and her dress size was nearly as big as her age. But alongside her plus-size looks, she had great curves, and her plus-size breasts caught plenty of eyes. Her arse wasn't exactly small either. She needed the curves because she was 5 foot nothing. Her blond hair had some natural curl, and her blue eyes almost always had a laugh, a smile, or a devious look in them. Her face was really gorgeous.
Sophie lived at home with her brother, 19 year old Jack. Jack was the opposite - in almost every way. To start with, he was 6'0 and ripped. He worked out a lot and his body was completely lean but with lots of muscles. He had dirty blond hair and was far more serious than his sister. He was at university in his first year. Because of the cost he'd decided to live at home and go to a local university, but that was helped by the fact he had moved into the basement and pretended it was his own place - only emerging to raid the fridge or get someone to do his washing. He certainly didn't seem to mind bringing girls back there.
Their parents both had jobs and active social lives, so they rarely saw them. Because Sophie's brother and parents were hardly ever around, she treated the house like it was hers, and most of the time she had her best friend with her Tracy was as big as Sophie, brunette, 5 inches taller, and much, much bossier. Tracy was 22 as well and they had been best friends for years. They both had part-time jobs and studied part time. Sophie was going to evening class studying psychology ands counseling while Tracy was doing business studies and accountancy.
None of the three of them had what you would call a steady partner. Jack was doing his best to sleep with every thin, fashionable girl in the university, while Sophie and Tracy had a habit of going out on Friday nights and trying to pull guys down in the pubs and clubs. Tracy was definitely clear on what she liked. She would wear tight leather dresses, and make sure that she went for older, submissive men. Obviously her bossiness extended into bed. And from what she said to Sophie there were plenty of men who liked to be told what to do, as well as being hurt and humiliated by the big girl. Most Friday's they succeeded in pulling guys, for despite their unfashionable size, both girls were naturally pretty, and fun as well as funny with it.
Sometimes they didn't get guys. It was one such Friday night when the two of them were coming back from a club when it all started. Sophie and Tracy were both quite tipsy, and neither had managed to snag anyone to satisfy their oversize desires. They both had strong sexual appetites and the lack of any guys to satisfy them was definitely on their minds. They got back to Sophie's to find the place apparently deserted, so they cracked open another bottle of wine and settled down on the couch to watch some bad late night TV.
After about 10 minutes, Jack appeared, wearing just his boxers. He had emerged from the basement to raid the fridge, and he briefly said hello to Sophie and Tracy. Tracy's eyes were glued to his muscled torso, occasionally wandering down to his well defined legs, and definitely stopping off at the lump in his boxers. He looked over and obviously could see the lust in Tracy's eyes, but there was no flicker of answering attraction. Jack didn't like big girls. He thought they were gross, fat and lazy. There was no way in hell he was going to even give Tracy a glimmer of hope.
After he went back downstairs, armed with a huge sandwich, a beer and big pile of fruit, Tracy said: "Oh my god. How can you handle having that walking around?"
Sophie replied: "You big pervert - you couldn't take your eyes off him. He's my brother!"
"He may be your brother, but he's so fit it's sick."
"Yeah, well you can dream on. He only dates sticks. If you are bigger than a size 8 he won't touch you. He's always making rude comments about how fat I am, or just random comments about big girls we pass in the streets. You haven't got a hope in hell. Anyway, from what I hear you are far too dominant in bed for my little brother."
"He's not little.... I could see his cock. It was practically falling out the bottom of his boxers!"
"Shut UP. I don't want to hear about my brother's cock; or his body; or anything else!"
Sophie might protest that she didn't want to hear about Tracy's fantasy for her brother, but even while Tracy had given it up for lost, Sophie started to imagine Jack and Tracy. The thought was appealing in so many ways. Firstly, it would pay Jack back for all his rude comments about "fat girls". She imagined teasing him back once he'd slept with Tracy, who was a good size 22 and weighed about twice what his average girlfriend did. Secondly, much as she liked Tracy, she couldn't help thinking it wouldn't be a bad thing to get Tracy off her high horse and a little less bossy. She certainly wasn't going to get her own way with Jack - he might be only 19, but he was no pushover. And finally, there was something else... a deeper darker desire to see the two of them: to see them fucking. She couldn't help it, but she couldn't get the image of him sliding into her best friend out of her head.
====================================
It was about two months later that Sophie got the ammunition to put her plan in operation. It was in her counseling class. They had a guest lecture on hypnotherapy, and he did a number of demonstrations, and then they split into pairs to just try it out. It was unusual to let students try hypno without full training, but the lecturer let them do it provided they followed his instructions to the letter. It was more of a guided meditation than proper hypnotherapy, but for some reason Sophie turned out to have a natural ability, and her partner was soon in a deep trance. When she got home she started reading up about hypnotherapy and hypnotism and the interest blossomed. Soon she had read several books and was talking about starting a new course in hypnotherapy the following year. All the books made a big deal of saying how the therapist must use the ability for good and must observe strict guidelines. But Sophie was feeling naughty. She was hatching a plan. Guidelines weren't going to stop Sophie once the devil inside her awoke, and she'd been feeling naughty for weeks now.
She started with her brother, figuring he was the harder nut to crack. One day they were chatting about his university sports team. He played tennis for the first team, but he just wasn't getting enough wins, and he was worried that another boy in his year was going to replace him. Sophie mentioned that a lot of research had shown that it was mainly mental strength and lack of self-doubt that separated world-class athletes from the rest. She pulled up some articles on her laptop to show him.
Then she said: "I wonder?" and then hesitated.
"What?"
"No, sorry it was nothing, it wouldn't be right anyway."
"Go on tell me. What is it?"
"Well you know I've been practicing hypnotherapy? I wondered if it would help you. Its just I'm not meant to do it because I'm not yet qualified. You could always see a proper hypnotherapist, but it is quite expensive."
"How much?"
"At least fifty quid a session, and you'd need at least 3 or 4, if not more."
"No way can I afford that sis. Can't you do it? It can't hurt even if it doesn't work."
"I'm really not meant to. They won't let me even do the course if they hear I've been doing this."
"Please sis? I promise not to tell anyone. Not even Trace. Not even mum and dad. Please?"
"I'll think about it," replied Sophie, but if Jack had spotted the gleam in her eye he would have known that she was definitely going to do it.
==========================================
Two weeks later, she had already done three sessions. She didn't want to mess Jack up too much, so she had researched hypnotherapy and sports, and had done her best to give him mental preparation to do his best and to not let his doubts or worries inhibit his tennis. Her first three sessions had been completely innocent, except for one thing. She was using the trance to test out her control on him, and particularly if she could stop him remembering what was said during the sessions. She had also read that the more a subject practiced it, the deeper the trance and the more effect the sessions would have.
The fourth session she had planned carefully. She wasn't going to mention Tracy. She wasn't going to do anything but simply implant a suggestion that he would stop hating big girls and see that they could be pretty in their own right. If he remembered it, or if he noticed, she could just claim she was taking the opportunity to stop him being so bigoted. They'd had enough arguments about it that he'd see it as a brother-sister joke and nothing worse. The session went brilliantly. By the end he was gently repeating to himself: "I will win my tennis matches. Big girls are pretty. I will always play my best. Thin girls are less pretty than big girls. Size 16 plus is beautiful," and so on.
After she led him out of the trance, she asked him if he was finding the sessions useful.
"Yes sis, its amazing. I've won my last three matches. And I feel so much more centred when I'm playing. It's really cool what you are doing. Especially as its just like having a quick nap. I thought there would be lots of talking and so forth, but I just fall asleep and wake up a better tennis player."
