Nike pushed Tommy off her adjusted her bikini top and walked out. Tommy was still breathing heavily with his dick exposed and swollen. He closed the door before anyone could see him recover his breath but forgot to lock it. He grabbed the book and took a pen in hand. He was going to look through it for the girl that assaulted him. He didn't know her name but she had to have something recognizable. Her hips had been notable after all. Suddenly the door was pulled open and Nike went in and locked it behind her. She put a hand on his mouth she was at first looking at his dick but then noticed the book and pen. She ripped it out of his hand and looked in it. "Is this... you?" She looked at the pen in his hand. "scream and I will hurt you, okay?" She whispered in his ear as she ripped the pen out of his other hand. She looked at him and leaned over the book. She was a simple person who knew what she liked so she was going ahead and write down her perverted fantasy but first a little test. She changed Tommy's date of birth making making him two years younger. She then looked at him. She saw the boys body shrink down into that of a younger boy, his penis getting thinner and shorter in the progress. "Wow, it really works, magic." She said to herself silently. She then looked at the kid and grinned. She looked at penis size which automatically shrunk with age but still stood at a ridiculous 7 inches. She put a two in front of the seven and watched and waited. Tommy's penis soon started growing longer and longer till it reached it's ridiculous new length however the kid didn't seem to notice all these changes but instead kept looking at her. She leaned forward. "Do as I say and put on your swimming trunks." The kid silently obeyed hoisting himself into his swimming drunks and reeling in his penis. When he finally collected it all in his swimming trunks a notable bulge had developed. Nike also noticed that the swimming trunks had changed designs but dismissed it as unimportant. She then noticed a section wherein she could write stuff about behaviour. She of course wrote that Tommy would be obedient and follow her wishes.
Nike looked at other page while Tommy was getting his trunks on. She realized she could change anyone she wanted, not just Tommy. She then realized she could change herself. Looking at her bust she quickly flipped through the book to find herself. She looked at her bust again and pondered. She then decided that she could always change her bust later again and chose to be a G cup and felt her chest filling out as she wrote it down. She felt a sting in her back and quickly added to her physical that her breast didn't cause her any discomfort. She then looked at them again and made them perkier. Tommy was still looking at her, often his glance went to her breasts. She grinned, they were perfect ridiculously huge and perfect. She grabbed Tommy's hand told him they were going to the pool. At first all eyes were on her as she turned the corner and then suddenly they were on Tommy who looked like he had a melon stuffed down his pants. Pool personel stopped her and beckoned at the boy. She grinned and put her finger behind the elastic holding it open just far enough to show off the coiled up monster. The woman that had asked her to do that finched and stepped back. Then quickly walked off forgetting to apologize. Nike then dragged Tommy to the bar while showing off his bulge to more people at the pool. She told Tommy to drink and made him drink more and more. Half an hour later Tommy looked uncomfortable. He asked to go to the toilet. Nike turned away and grinned at herself. Followed him to the toileted and then pushed him toward the urinals at the door and told him to use the urinals. Tommy hoisted his cock out of his swimming trunks. Nike licked her lips as she saw Tommy struggle with his massive penis and the embarrassment of the grown man beside him. The dark skinned man was startled as he had noticed what was happening beside him. Nike took at the book again and opened it at Tommy's page. Time for another accident.
She grinned as she increased Tommy's sexual awareness from non to high and his libido from zero to 70%. She then wrote that he wouldn't get hard till she wanted him to. As the dark skinned man walked out muttering something about a joke. Tommy was still waggling his penis trying to get more urine to come out. Nike called him over. "That's enough, to the pool again." She grabbed his hand and pulled him along. She saw the same female poolguard at the pool and told Tommy to go to her at her signal. She opened the book at looked for the name on her nametag. "Alice, ah there you are." She said to herself in her head. The girls features were all average but that would soon change. She had been taller than Nike she Nike made her shorter. She gave her E cup breasts but reduced her hips some while thinning her waist and made her face less plump looking. She ordered Tommy to walk to her and ask her to help with something. Intentionally she made it ambiguous. The girl was startled as Tommy approached her Tommy then asked her the question. The girl looked confused and leaned forward exposing some cleavage beneath her shirt-over-bikini. Nike grinned and willed Tommy to get hard. Tommy's massive bulge got larger stretching the elastic band until his lenght popped out. The girl gasped and flipped and fell on her behind as Tommy grabbed his swelling crotch. Nike was feeling especially excited from all of this and felt her nipples harden beneath her swimsuit. She added uncontrollable sexual appetite to Alice's personality factors.
Alice suddenly shot forward and grabbed Tommy's growing erection. It slowly grew longer and longer reaching 35 inches almost 3 feet. Alice started removing her bottom and removed her skirt. Tommy surprisngly got himself up and was trying to push Alice down in his own horny stupidity. The girl however overpowered him and grabbed his penis shoving it into herself and moaning loudly. Nike herself was feeling hot from seeing this. Her crotch was moist and her breasts felt full. Then suddenly her top gave and her perky mounts burst free. She gasped as her top flew off but moaned slightly at the same time. She looked at her tits. They seemed even larger. Nike realized while she had increased her chest volume she didn't change any other feature. Her chest always swelled quite a bit proportionately when she got horny. Her chest was tiny then she now her chest while swelling the same amount proportionally gained a lot more cup sizes than before. Her chest felt very full when they finished swelling. She touched her nipples and lifted them then glanced at Tommy's massive cock. Her dreamcock. She started walking toward them. Her very perky breasts now had a circumference was now larger than her own head yet even in this swollen state she wasn't bothered by their size but rather she was very horny. Her however nipples poked out of her mounts dwarfed by the volume of her chest.
She pushed Alice off Tommy and was about the grab Tommy's cock when someone grabbed her shoulder. Soon after Alice got on earful and Tommy also got some verbal abuse but far milder. Nike was forced to use a towel to cover up her still swollen chest. She looked at Tommy after they were let go. They were told to leave the pool right away. She was disappointed by the ending but looked forward to using the book and getting some alone time with Tommy's cock.
