“Hey little brother. You’ve been good and so It’s time for your weekly release.” Julie said with a smile towards her very excited brother. “Oh thank you Julie, I’ve been looking forward to this all week.” Replied James. Julie took out her key and unlocked the chastity cage from his penis and allowed it to spring free, rapidly growing erect. “I know how much faster this goes when I let you touch these.” She said to him as she took off her shirt and bra revealing her perky C cup breasts that her little brother enjoyed so much. James moaned in pleasure at groping Julie’s breasts, as his sister gently took his erection in her hand and began stroking it up and down with a loose fist as she gently kneaded his testicles. James thought about what put him in this arrangement with his sister. Ever since he started getting erections he’d become very interested in his older sister. His sister was very fit, with a toned body, perky breasts that seemed to still be growing, a perfectly round ass, long blonde hair, piercing blue eyes, as well as a lovely smile. He used to masturbate constantly to the thoughts of her body, usually several times a day. It was quite the shock when one day, his sister revealed she had enough of his incessant masturbating, kicked his balls to the point where he couldn’t stand up, and locked his penis in chastity. He had protested greatly at having his penis locked away, but when his sister had informed him that he would be let out to orgasm once a week if he behaved, he had immediately complied. Especially when Julie had informed him he would get to touch her breasts, that alone was almost enough to make him orgasm. Julie had only laughed when she pressed him on what he jerked off too and realized it was her. She was surprised when he revealed that he jerked off a lot to the thought of her castrating him. James insisted it was just a fantasy and didn’t want it to happen as he said he loved to cum. During the week James was driven crazy with arousal, but it all seemed worth it when he was groping his sisters chest while she jerked him off. A shiver of pleasure brought his mind back to the present. “You know James, if I just removed your balls, you wouldn’t need me to do this for you anymore. It would be so easy, maybe I should just do it now.” Julie said with a smirk as she continued to stroke his hard on. “Noooo, Julie don’t take them.” James pleaded. “Relax little brother, I’m just messing with you.” Julie replied with a giggle. James relaxed and enjoyed the feel of her hands on his manhood, as he gave her breasts another squeeze. Suddenly the soft feel of her boobs in time with her strokes made his orgasm overwhelm him. “Julie I’m cumming!” James cried out. Julie then, much to his amazement, took the head of his cock in her mouth and flicked and swirled her tongue around the tip as his semen pulsed into her soft, warm mouth. Her luminous eyes bored into his and twinkled in amusement as he shivered and moaned in thrall to his orgasm. “Ahhh. Julie, thank you. That-that was amazing.” he said as she released the tip of his penis from her mouth with an audible pop. “You’re welcome little brother. Now time to go back in your cage.” Julie responded as much to James’ dismay, locked his penis back up and put on her bra and shirt. “Now you go occupy yourself, but remember be good or you won’t get a release next week.” Julie reminded him. James hated the part of getting locked back up, but didn’t dare protest at risk of not getting his next release. He was completely at his sisters mercy. It had been a few days since his last release and James continued struggling with arousal. As usual, Julie had made him do everything for her, such as making her meals and rubbing her feet. James’ penis throbbed in his cage as his sister walked in wearing a tight, low cut shirt that really showed off her boobs. “Hey little brother, you know I just got this knife at the store. I’m thinking I should just cut your penis off with it.” Julie spoke with a big smile. “NO NOT MY PENIS! JULIE PLEASE DON’T CUT IT OFF! I LOVE MY PENIS!” James screamed and begged “Relax James it’s only a joke, your penis is safe.” Julie replied with a laugh. James felt uneasy as he thought he heard her mumble “for now.” Under her breath. James desperately wanted out of his cage, due to his extreme arousal, but didn’t dare ask. The next day Julie and James were sitting in the living room watching tv. “You know little brother, it would be so easy for me to just castrate you, ending your orgasms forever.” Julie declared to James out of the blue. “No, Julie don’t. I really like having my balls.” James whimpered. “It’s not a big deal, it’s not like they’re good for anything.” Julie teased “Julie stop. I love my balls.” James whined “It’s just so fun to mess with you little brother. I’ll see you later.” Julie answered. She playfully tugged on his caged penis as she left. The end of the week had finally arrived. James was excited as his sister walked in to the room with the key. He was way more aroused than usual and was primed to explode. Julie gave him a wicked smirk as she removed her shirt, exposing her breasts to the horny boy. “Go ahead and give them a squeeze.” Julie informed James as she unlocked his penis. James’ penis quickly grew fully erect. He reached out and began furiously squeezing his sisters boobs. “Wow Julie, your boobs seem bigger.” James said in amazement. “They’re growing. When I lay in bed topless every night I can tell. They’re going to be a D cup soon.” Julie responded gleefully. Just as julie was about to begin stroking his cock, her words combined with the feel of her breasts made James shoot his load. “Gah.” James groaned in a mix of pleasure and frustration at not getting to have his penis stimulated before ejaculating. “Okay, back in your cage little brother.” Julie voiced with a hint of glee in her voice “What do you mean, you didn’t even touch it yet.” James protested “I don’t care, you ejaculated and that’s all that matters.” Julie retorted as she locked up James’ now flaccid penis, much to his annoyance. “But Julie…” James adjured “You’ll have to wait until next week to be let out again. But remember, only if you’re good.” James only groaned in frustration at her words. The next day Julie met her little brother in the kitchen. “Julie I have to admit, I’ve always had a bit of a crush on you and I love your boobs. Just being in the same room as you drives me crazy with arousal.” James broke the silence. “Well James I have some news for you that might help with that problem. I’m going to castrate you soon.” Replied Julie with a big smile. “Julie no. Tell me you’re just messing around again.” James replied nervously. “I’m afraid not little brother. I’ve been making you cum every week for years. It’s time for your balls to go. I think you’ve had them long enough. Soon I’ll castrate you, so enjoy your manhood while you still have it.” Julie responded with a wicked smile. “No Julie, I love our arrangement I don’t want it to end.” Said James as he began to tear up “I’m afraid all good things have to come to an end eventually.” Julie answered. James only sniffled at the realization that the amazing deal he had with his sister was coming to be finished for good. A couple of days had gone by since Julie told him she was going to castrate him and James had grown increasingly worried. “Julie I love you. I can’t live without our arrangement. Please spare my manhood.” James begged as he ran into Julie in the living room. “Don’t worry James, once a few weeks go by after your balls are removed, you won’t even miss our arrangement.” Julie replied as she patted him on the head and left. James was beginning to panic as his sister didn’t say when she was going to remove his balls, only that it was happening soon. He only hoped he could convince her to not go through with it or at the very least have more orgasms first. James spent the rest of the week terrified. Julie kept squeezing his balls saying things like “these are going to be gone real soon, so enjoy them while you have them.” Which would send shivers up his spine. The end of the week had arrived and James was looking forward to feeling his sisters breasts and having another orgasm, even if his time enjoying them was rapidly running out. Julie unlocked his penis from his chastity cage and quickly removed her shirt and bra. “Check it out James, I’m officially a D cup now. Have a feel.” James was mesmerized as he began squeezing them and became fully erect in an instant. He moaned very loud as Julie’s hand wrapped around his cock and began lightly stroking it as her other hand softly squeezed hid balls. “Julie, that feels so good. Thank you.” “Well I noticed you’ve been extra good this week, so I’m going to take my time with you today.” Julie replied with an unnerving smile. James was squeezing her breasts with more enthusiasm than usual. Julie could tell how enthralled he was with their bigger size. She wondered if he would still have the same enthusiasm for her boobs after his balls were gone. Julie continued to stroke James’ cock and gently knead his testicles for several more minutes and could tell he was growing closer to orgasm. Julie positioned her breasts in front of his penis and said “Tell me when you’re just about to cum and you can finish on my breasts.” James eyes lit up at her words and in less than a minute, he was about to achieve his most desired orgasm. “Julie I’m gonna cum! He cried out. Just then Julies hands left his manhood completely. “What? Why did you stop? I’m about to orgasm, just a couple of seconds more will do.” James grumped. “James, it’s time.” Julie responded “Time for my orgasm?” James asked “I’m afraid not little brother. It’s time for me to remove these balls of yours. I figured since I’m gonna take your balls today, there’s no sense in me cleaning up a messy orgasm too.” Julie answered “Julie no! Don’t remove my balls, they’re so precious to me. I love our current arrangement. Can’t you just keep making me orgasm? It feels astounding.” James cried. James tried to cover his manhood in fear, but Julie had already grabbed his balls and squeezed rather forcefully to subdue him. In James’ eagerness to feel his sisters boobs and her hands on his manhood once more, he had missed the large scissors and first aid kit next to her on the couch. Julie reached out with her free hand and grabbed the scissors. “Julie don’t take my balls away. I love orgasms. I’ve been good. I’ve done everything you ask. I just want to keep feeling pleasure. our deal is my favorite thing in the world. I won’t even be able to enjoy touching your boobs without my balls.” James begged her to spare him. “You have been good James. But castrating boys is my favorite thing in the world and I just can’t wait any longer to remove your balls. After a few weeks you won’t even miss them. Plus, I won’t have to be bothered by the gooey, sticky semen these balls produce ever again.” Julie replied happily. “No no, I don’t want to give up my balls! Please Julie, don’t end our awesome deal.” James pleaded for mercy. “You’ve had these silly balls long enough, little brother. It’s time for them to go. Your crotch will look so much neater without them too. Think about it this way, after I’m done removing them, you won’t care about my boobs at all. You’ll be free to find new things to interest you.” Julie insisted “But Julie, I don’t want to find other interest I love our current deal. It’s the best thing ever. Please let’s keep it the same. I adore you and your touch, don’t make that end for me.” James said trying not to sob. “Oh James, you’ll see, your life will be much better without your balls. You’ll go from constantly obsessing over my tits and your next orgasm to having new interests entirely. This really is for the best.” Julie retorted. “No Julie it isn’t for the best. I can’t live without—- yow!” James had tried continuing to talk his sister out of her plan, but she closed the sharp scissors down and cleanly separated his balls from his body. Ending his time as a man. “Noooo! My balls! My precious balls!” James sobbed. “They’re just a pair of balls, it’s not that big of a deal little brother. Think about all the free time you’ll have without spending so much time squeezing my boobs and having me make you cum each week.” Julie responded in a mockingly consoling tone as she patched him up. She didn’t even give him the pleasure of a final orgasm. “The good news is you won’t need your chastity cage anymore now that I don’t have to worry about you getting into trouble with that pesky manhood of yours. That’s something to be grateful for.” “Julie, why?” James sniveled “That’s what’s so great about you no longer having balls.” Julie continued ignoring his question “I’ll never have to stroke your hard cock and suck your penis as you cum again. I must admit I liked when you massaged my boobs, but don’t worry I have a new guy for that now. I figured you wouldn’t have the same enthusiasm for the task without your balls.” James just sat on the ground and loudly cried. Julie stood up and patted him on the head as she began to walk out of the room saying “don’t worry little brother, you’ll find that life will be much easier for you without the constant distraction from your balls. In time, you’ll thank me for removing them. Male orgasms are so messy anyways. Who needs them?” “I needed them.” James quietly replied in between sobs. Julie simply ignored her brothers comment, but said one last thing before she fully left the room “I’m so happy right now, you have no idea. This is the best day ever.” James simply continued to cry at his loss and the pleasure he would never feel again. In the days following, James truly began to realize the extent of his loss. Usually when his sister dressed provocatively, James would feel all tingly in his groin, mixed with the slight pain of his penis straining against his cage. Now, James felt nothing at the sight. He already missed the fun tingle of arousal and cried more that he would never feel it again. The deal he had with his sister was changed forever and only she benefited from their new arrangement.
