Thirst Trap

"Hold on, let me adjust real quick," Sam pulled the bottom of his sports bra up, letting his massive breast peek out. He put a finger on his lip as he stared at himself in the mirror, "Still missing something." He saw Lucy behind him getting antsy.

"You almost done? You're getting way too into this..." Sam smiled to himself seeing the tent she was pitching watching Sam pose in front of the mirror. Inspiration struck and she pulled her waistband down just enough to be exciting without passing too far.

"Hey, you're the one who made me stay as your sister so you could win a stupid bet. I only swapped with her to get us alcohol. Besides who asked you to swap with her boyfriend?" Sam practiced his poses in the mirror before nodding to himself in satisfaction, "Perfect. Good thing I went for the full wax." Sam strolled back over to Lucy and struck a pose, "Ok, [babe] take the picture!" Sam winked at Lucy, enjoying watching her blush. [Damn he's cute when he's bashful. She. Damn it.] Amy's body was really starting to effect Sam. He knew he should probably stop "exploring" Amy's body with how much he was changing, but it felt way too good. Besides, he'd never get another chance like this ever again. Full access to the body of the most beautiful woman in the world is hard to come by. Especially since Sam could make her do anything he wanted. Lucy took the picture and Sam sauntered over to her to collect the phone. He quickly opened Amy's Instagram account and posted his latest picture. "Just finished a hard workout! God I hate remembering all these hashtags. Ok, and posted! How do you think Amy would feel if she knew it was me behind her skyrocketing success instead of you?" Lucy shrugged,

"It makes sense you'd know what guys like. What does surprise me is how popular you are with the girls." She chuckled as she thought about it, "But I think she'd be a little pissed that you were able to become a popular influencer so quickly. How many followers are you at now?"

"I'm up to 250k now. If things continue like this I'll hit 500k before the month ends." Lucy let out a whistle.

"Amy was only at like 2k when this started." She grew excited, "and as long as you keep growing we can stay!" Sam couldn't help but roll his eyes.

"Relax, I like being an adult just as much as you do. With the offers I've been getting through social media I've been making way more than my day job." Sam knew the real reason both of them wanted to stay. He'd heard Lucy vigorously masturbating in her new body countless times. Recently he'd been catching her staring at his ass or looking down his cleavage when she thought he wasn't looking. Not that he was innocent of that himself, catching himself admiring Corey's body more than he'd like to admit. "Oh yeah, I'm going out with the girls tonight after dinner so don't wait up!" Lucy gave him a strange look.

"At first it was obvious you were acting or just playing around, but now its like you're really Amy. You're hanging out with her friends, going to her job and chatting with my parents. You walk, talk and act like her. You're even drinking coffee and eating salads. You hated those. I mean we had an hour long conversation about shoes and makeup the other day!"

"I don't know why that bothers you. As long as I'm in this body I am Amy and it makes it easier if nobody suspects anything. And let's not pretend you haven't been acting like Corey, Mr. 'fantasy football' and 'It's boy's night.' Plus we both like working out together and being into this health and fitness thing and living together. We get to hangout and watch movies together and don't have to worry about homework. Plus I know you love my cooking!" Lucy frowned as they got into the car,

"I like Amy's cooking, and you always want to watch horror movies or Rom-coms now." [Well that's not fair. I always liked cooking I just sucked at it. Who cares if I'm borrowing skills for it.] Sam had always stayed away from horror movies as he was a bit of a scaredy-cat even if he enjoyed them, but with Amy's outgoing and fearless personality as well as her love of horror movies, he finally got to enjoy them. Rom-coms he'd stayed away from since they weren't "manly," even if he had a bit of a soft spot, but with Amy's interests supplementing his own Sam could now fully enjoy them. It's not like Sam didn't enjoy superhero movies still, he just wanted to experience these while he could. "Wait, that's not the point! We're supposed to be best friends, but you're making me confused!" Sam didn't know how to respond.

Sam and Lucy had always been best friends. They were into the same stuff and got along great. Some people said they would make a great couple but it was never like that. They were always just close platonic friends. Ever since the swap, however, there was something more there. A spark. It was separate from the growing sexual tension, which was getting almost unbearable for Sam. Whenever he thought about his "boyfriend" he felt happy and warm. Little gestures like taking Sam out for lunch felt much more romantic. Lucy had even shown up with flowers at work the other day when Sam was having a rough day, and though he knew it was at the original Corey's suggestion, he couldn't help his heart racing.

Speaking of the original Corey-though he'd been hesitant at first he'd really taken to Lucy's body. Where Amy was unbelievably curvy and sexy, Lucy was extremely cute. They'd begun texting as they were in the same boat, but had become really close and started treating each other like real sisters. They'd recently started referring to each other as "sis" or "Amy" and "Lucy." Sam's new little sister confided in him that she and "Sam" had begun dating. She apparently liked being the submissive girl in the relationship and she and "Sam" had already done the deed. Sam had originally been a little upset, but after what he'd done to this body he realized that wasn't very fair of him. He was happy for the two of them. Amy, who seemed so upset at first, loved being a boy. She'd messaged Sam, "No periods, creeps, makeup or heels? It's awesome. Not to mention having a cock feels incredible. You haven't ruined anything yet, so take your time."

When they got home Lucy sprinted off too the shower before Sam could say anything. He felt bad. The things he'd done to "tease" Lucy had apparently been rough on her. Sam had to be honest with himself: he wasn't kissing her cheek or holding her hand to tease her, he was doing it to assuage his growing romantic feelings. He went over to the bathroom to knock and apologize when he heard Lucy through the door moaning. "Oh my god Amy. Fuck yes. I love your tits." Sam flushed bright red. Lucy wasn't jerking off to her own body, she was jerking off to him. No. [He] was jerking off to [her]. She was Amy: A woman with needs, and she wanted her boyfriend. And since he seemed to be just as wanting she saw no harm in going for it. With a smile she quickly stripped before opening the door and stepping inside. Lucy turned to her, "Amy, I mean Sam what the fu..." trailing off as she caught sight of Amy's naked form. Her heart was pounding as she walked toward Corey's rigid member.

"Look I know we both want this. I heard you earlier and I feel the same way. I want you Corey." She looked up at him.

"But you're, I mean Amy, is my sister..." She shook her head.

"Look at yourself in the mirror. Are you Lucy?" He slowly shook his head. "Or are you my boyfriend, Corey?" He nodded. "Then I'm not your sister, Amy. I'm Amy, your hot Asian girlfriend. And I want you." Their lips slowly approached each other before they were hungrily devouring each other's bodies. When they finished all the awkward tension was gone and they became the grossly in love couple they had both desired to be but had been holding themselves back from.

"What about the Sam and Lucy? What do we do if they want to swap back?" Amy smiled as Corey's hand slipped to her ass.

“I don’t think that’ll be a problem. They’re already dating and both of them have been subtly asking to keep extending. I think as long as we want to stay this way, we can. So my love, what do you say?”

“I’m in.”
