Thor awoke early that morning to his brother's groans and sounds of struggle and blearily wiped his eyes, turning to the bathroom, where he looked in and saw Loki changing. It seemed he was trying to fit into his old, smaller binder and struggling to do so. Thor got up and stood in the doorway, watching Loki struggle to fit in his old binder from high school.
"Loki, come on. You know that won't fit."
Loki shot a glare at him. "Yes it will. It has to. My other one is still wet from washing it last night and I don't wanna wear a wet binder at work all day." Loki just got a job at a nearby bookstore. Thor told him he didn't have to, but he insisted on helping with the rent.
Thor had a good job as a lawyer with a good company, and had no problem paying in full for the both of them, but Loki felt bad being cooped up inside all the time and not contributing towards the rent. The worst part about Loki going out more was the binder, however. Before, when Loki was home, he didn't care too much about his chest. He wore big shirts, but other than that he didn't hide it. He had pretty big breasts, and they were certainly noticeable, but when they were home alone, he didn't care.
Other people's perception of his body as feminine was what drove him to start wearing his binder, even inside the house. He began getting really dysphoric after spending so much time outside, in the general public. And the general public was cruel. They were idiots. And worst of all, they made Loki hate himself. Thor loved his brother's tits. He always loved them, even before he had learned to see them as masculine. Before they had been feminine and beautiful. Now they were masculine and beautiful.
He loved to get his mouth and tongue and hands all over them, groping them, making his nipples harden and poke through his shirts. He loved when Loki threw his binder off and in the corner of the room after coming home, how his tits bounced freely out of it. He loved when he started testosterone and they got all hairy. He loved how they bounced when he was getting fucked. Thor wouldn't fuck him unless he could see or grope at his warm, soft, hairy titties. They were delectable.
And Thor so loathed that Loki was beginning to hate them and feel dysphoric about them. "You know, you can take a day off. Maybe just stay home with me, no binder, nothing. Maybe a sports bra, if you really feel uncomfortable with them bare."
Loki sighed. "No, Thor. I don't even want to look at them. Not even if we're alone."
"Well you're not wearing that one." Thor put his foot down and walked over to Loki, pulling it off of him, gently. "Your breasts are beautiful, brother. You should let them out to breathe." Thor hadn't got to have sex with Loki in weeks with his tits out. Loki had insisted on wearing his binder even during sex. It was like the world was trying to suck all the joy out of both his and Thor's life.
"I've been thinking about top surgery recently." Loki dropped, suddenly. He covered his chest with his arms and turned away slightly from Thor.
Thor frowned slightly. "Why? Loki, you're perfect the way you are. I love your body. Having breasts doesn't make you a woman. Having any body part doesn't make you a woman." Thor began to internally panic. He didn't want to be weird, or sound like a freak or a chaser, but he loved his brother's breasts. They were perfect, and he hated how dysphoric the outside world was making him to make him want top surgery all of a sudden.
"Where is this coming from? You used to love your breasts as much as I did. You told me you never wanted top surgery before."
"That was before I kept getting misgendered every day. Thor, it's awful. I know you understand this pain, because nobody ever sees you as you truly are except for those you tell, but it's just awful for me. I'm tired of it."
Thor shook his head. "I understand if you want it, and if you really do want this surgery, I'll pay for it. But I do want you to know I adore you just the way you are. Other people's opinions don't matter and you shouldn't let them control your own perception of gender and how you feel about your body. If you really want this surgery, fine, but I don't want you to get it for anybody but yourself."
Loki nods and lets a tear slip from his eye. "Maybe I should take a day off and just go without the binder."
Thor smiles and kisses him. "Thank you. You've been wearing it far too much. I don't think that's even healthy."
Loki nodded. "Maybe it's not. It is hard to breathe in."
Thor took him back to bed after he called his employer to tell him he was sick, then rested his head on his warm, soft chest like he hadn't been able to do in so long. It was perfect.
Thor woke up earlier than Loki did the second time, and slipped quietly from their bed. He knew what he was about to do was wrong, but God, he loved his little brother's tits, and it was bad for his health to keep wearing his binder. He slipped into the bathroom, where the binder was hanging on the towel rack. He took it, as well as the old, smaller binder from high school and took them out to the dumpster behind their apartment building and dropped them in. It was wrong, so wrong, but he needed to see his little brother's tits. They were too perfect, too soft, too warm to hide. They had a perfect bounce to them too. God, he was so excited to see them bounce.
Even though he knew it made his brother dysphoric and it would humiliate him, a part of him wanting to go out in public with his little brother wearing nothing but a tight shirt on. His tits were definitely not small, but not massive either. They were on the medium to big scale. But the way they bounced, oh, Thor wanted to show that to the world. He wanted to have his little brother sitting on his lap, bouncing his tits while other people watched them. He wanted to grope his tits in public, pull up his shirt and show off a cute push-up bra. He didn't see his brother's tits as womanly, and he hated how other people did.
Thor felt guilty when Loki awoke and began panicking about his binder. "I swear, I left it right there to dry!"
Thor brought him into his arms. "It's okay, brother. You don't need it today anyway, you're not going anywhere. Let's just go watch a movie on the couch and calm down, okay?"
Loki agreed and they sat down together, with Loki on Thor's lap. After the movie started, Thor began making moves to grope at Loki's tits. He snaked his hand up his shirt and gently wrapped his hand around one squishy breast, massaging it in his hand and brushing his thumb over Loki's perky, hard nipple.
Loki moaned out loud and blushed. "Sister...come on. You know I'm feeling dysphoric."
Thor pulled his hand out with a whine. "I'm sorry baby, you know how much I love to grope and feel at your chest. It's just so soft and warm. It's soothing to play with." He pouted.
Loki felt bad, but stood his ground. "Maybe later. I'm just not feeling good."
"That's fine."
---
Thor lied, it wasn't fine. A week passed since then, and Loki had started binding with bandages again, like he was in ninth grade and stupid. Thor had yelled at him for it, but he just started doing it secretly before work.
Thor got the call around noon. Loki was taken to the hospital. He rushed there immediately, and saw Loki in the bed, picking at a jello cup. "Loki! What the fuck happened!?"
He looked humiliated and depressed. "I- I passed out. I passed out and I fell off the ladder, because I was restocking the shelves. I know you said not to use bandages, but I did. And- the paramedics cut them off of me in front of the whole store. It was awful. I quit my job. I told them I wouldn't sue. I'm fine, I just overexerted myself and I was wearing bandages instead of a proper binder, I just passed out. The worst part was everyone seeing my chest."
Thor hugged him and cried. "No. No more of that. I can't take it anymore. No bandages. No binder, even. The most I want you in is a sports bra."
Loki was mad, reasonably so. He tried to yell, he tried to argue, but Thor threatened to send him back to Odin. It was a cruel thing to say, knowing how awful their father was, but Loki had to listen to him.
Loki was still upset when they got home, but Thor had a plan. One of his friends, Tony Stark, had told him about this. He sent him a link to this weird, underground, hypnosis file website. He downloaded a few onto his phone and planned to have Loki listen to them in his sleep. He just wanted his little brother to feel comfortable in his body again. He didn't want to control his little brother like this, but he wanted him to feel at peace with himself. And it wouldn't hurt to see his tits bouncing up and down as he fucked his tight pussy and rubbed his cute little t-dick.
As Loki fell asleep, back turned to Thor, Thor put the playlist on. It was a simple playlist, only an hour and a half long. He slipped the headphones over Loki's ears and set a timer on his phone to remind him to take the headphones off when the playlist was over. If he left it running afterwards, the app would continue running recommendations, and he didn't vet the other ones to make sure they were safe and would do what he wanted.
When he and Loki awoke the next morning, Thor felt up Loki's chest, just to get a feel for if the hypnosis worked. Loki moaned and leaned into his touch.
"Oh, Thor.." he moaned and placed his hand over his big sister's.
"Loki, are you feeling alright?" He said as he squeezed his soft breast lightly. "I know you were pretty upset yesterday."
"I- I don't know what came over me...I was just feeling so awful about how people perceived me. I don't know now. I'm feeling better."
"It's okay, sweetie. Do you still want top surgery?"
Loki shook his head and responded almost immediately. "Oh, no. No, absolutely not. That was- I don't know. I like it much better with your hands groping my tits. They're too good to throw away. Too soft and plump."
"Aw, I agree. If anything, you should show them off more."
Loki paused. "I- I guess I should. But not in public."
"Whatever you're comfortable with."

It took just three more days of hypnosis for Loki to be willing to go out in public without a binder on. He pulled on a sports bra (one with a lace edge. He hadn't worn that one in a while.) and then went to the grocery store with Thor. He got a few stares, but Thor stared them down even harder. Thor really couldn't keep his eyes off his brother's chest. It had been years since Loki had been outside without a binder on, and it was almost too much for Thor. Knowing that people were looking at his brother's titties but him made him want to punch a hole in the wall, but knowing that nobody else could ever touch them but him made him feel so full of pride and smugness. Those were his. His tits.
"Brother, do you think I look like a girl right now?" Loki asked him, wary and curled up on himself, nervous and ashamed. The hypnosis still didn't get rid of the anxiousness and dysphoria associated with the outside world's perception of him.
Thor sighed deeply and pushed down anger at their society and culture. "No, absolutely not. You look like a man. A very sexy man. The hottest one ever. With the best pair of tits."
Loki smiled at that and they kept on their shopping trip. That was, until they got to check out. Loki was putting a few bags of vegetables on the conveyor belt when the cashier turned to Loki and said, "excuse me ma'am, those broccoli bags are expired. I'm sorry they shouldn't have been out there."
Loki instantly curled up in on himself and tried to push down the rage at being referred to as ma'am. Fortunately, his sister had no problem with causing a scene in public for the sake of Loki.
"Excuse me, that's not a woman. That's my husband. Refer to him as sir."
The cashier looked embarrassed and nodded. "Sorry sir. And sorry to your husband."
Thor didn't mind being called sir most days, but some days he really wanted to be called ma'am. Today was one of those days. "And I'm ma'am, not sir."
The cashier looked even more embarrassed and a little annoyed. "Okay, well I'm sorry ma'am."
Loki felt just as embarrassed as that cashier. He didn't like correcting people. He always felt like his identity was a burden on the general public, or that correcting someone would put him at risk. But Thor would always stand up for him. He was a good big sister like that.
They finished purchasing their things, putting the broccoli back, and left. "That woman thought I looked like a girl."
"That woman probably dropped out of middle school, I wouldn't worry about it, my love."
Loki clung to his arm and kissed his shoulder. "I love you, brother."
"I love you too. And trust me, nobody will ever hurt you under my watch, okay? I will always be here to protect you. And fight off any assholes who think that I won't or can't beat their ass for disrespecting you."
"Will you fuck me when we get home? On the couch, slowly, while we watch the new episode of Bridgerton."
Thor smiled. "Of course."

Thor knew he'd made a mistake. But he didn't think anything of it the first time it happened, so he kept it up. Loki seemed fine. So what if he left the hypnosis running the whole night? The ones that the app recommended didn't seem all too bad. That was until Loki's bra started getting too small. Until one day he awoke to find it was so small that the fat was spilling out the sides, and it started ripping.
"Thor, what's happening? I swear, I feel like I'm gaining weight, but it's only in my chest. Feel like all my clothes are too tight, but only in this one area."
Thor felt mesmerized by the sight. Once that was Loki's biggest bra. Now his boobs were so big it was ripping. "Oh, poor thing." He said, but felt nothing but arousal. His cock was hardening in his panties, and he stroked it lazily. "Want me to rub them? You're probably just having a little growth spurt."
Loki nodded and crawled into Thor's lap, grinding his t-dick against the bulge in his panties as he slipped the bra off. "Sister, they ache a little bit, they feel so warm..." He moans as Thor starts rubbing his nipples, and kisses his warm breast.
Thor smiled. "You're getting a lot of hair growing here." He massaged the flesh softly and felt the soft, silky black hairs growing all over them. He used to shave, but hadn't had the time recently. Thor was grateful for it, as he was for many things these days. He licked at the little tuft of fur between Loki's breasts, kissing at it.
Loki moaned. "God, I'm so sensitive right there, sister..."
Thor kissed right on his nipple, and Loki squirmed. "Thor! Oh..." He squeaked as Thor began massaging his sensitive tissue, feeling it, then bouncing them in his big, calloused hands. Loki ground down on his hardening, large penis that was straining against the cotton of his crimson panties. Loki could see the tip through the fabric and the little wet bead of pre-cum leaking through.
"Do you want big sister to fuck you, Loki?" Thor growled, low and soft right in his ear. Loki shuddered at the tone Thor took and pressed his tits to Thor's and rubbed his t-dick and wet pussy against Thor's hardening cock.
"Yes, please." Loki slipped into his submissive headspace and buried his face in Thor's shoulder. "Be gentle, please."
Thor kissed his forehead. "Of course, little brother. I would never be anything less than gentle with such a fragile little thing like you." Thor freed his huge, throbbing, dripping cock from his panties and held it up to Loki's stomach. "See how deep I'll be inside you?"
Loki had to lean back to see Thor's cock without his breasts in the way, and he whined when he saw. It went all the way up his tummy. "You're gonna be so deep inside me..." He rubbed his t-dick against the shaft and steadied himself on Thor's shoulders.
Thor smiled and nodded. "Very deep. Nobody will ever reach inside this far but me. Ever. I was your first, and I'll always be your only. Just me." Thor held his waist tightly, possessively. "You're mine. And I'm yours."
Loki nodded. "You're mine. And I'm yours," he repeated back to him.
Thor felt with his fingers to see if Loki was slick enough to enter, and oh...he was. Thor pulled back his fingers and a string of slick followed. He licked it up and Loki bit his lip. "Are you ready, my love?"
Loki nodded. "Yes. Hurry up, I'm getting impatient."
Thor laughed, amused by his little brother's brattiness, and lined up his cock with Loki's warm, wet hole. Then he shoved in, making Loki scream with delight. "Oh, fuck! Oh, Thor! That was too much, you asshole!"
Thor smirked. "I'm sorry, sweetie." He feigned innocence and sympathy. "You said you were impatient; I didn't want to disappoint."
Loki huffed and pouted as he squirmed on Thor's too-big cock. "It's too big for you to just be shoving it inside."
"Poor thing."
Loki pouted even more. "You're so mean."
"No, I'm not. I just wanted to help you. You said you were feeling impatient, my love. I just complied."
Loki bounced slightly on his cock, testing the waters. Thor always loved the feeling of Loki's pussy, but he was stuck, mesmerized, staring at his perky, bouncy tits. Maybe he should boost the hypnosis, just a little. It couldn't hurt if they were a little bigger, right?
Thor kissed and lapped at his pretty titties. "I wouldn't mind if they got bigger, would you?"
Loki paused. "I..I guess not."
Thor smirked and started bouncing Loki on his cock, easily making him cock-drunk. "I guess then it wouldn't be too bad if they continued to grow...
TO BE CONTINUED....
