It was an unusual request that Chicken made. Cow did not expect her first time to start like this. She had never considered that a boy would find noses sexy. But she was happy to feel wanted, regardless of which part of her excited him. She licked her left hand, grabbed his penis, and started slowly rubbing it up and down its length. She then brought her face close to Chicken's face, wiggled her nostrils, slowly inhaled and then exhaled onto his face and chest quite forcefully. She had good lung capacity. The process of blowing air on him took a little over three seconds to complete. Chicken felt the slightly warm air flowing over his beak, his waddle and his chest. It felt very relaxing. And arousing. His cock twitched in her hand. She then rubbed her nostrils down the length of his neck, chest and stomach. During the first forward-and-back motion, she held her breath. During the second, she "vaccumed" his chest and belly by inhaling as her snout went down his front, almost reaching his penis. When she rubbed her nose upward, she started exhaling onto him, his feathers parting a little as the air travelled through them. Chicken loved every second of it. He started moaning a little. Cow giggled slightly upon hearing him. She tenderly kissed the side of his face. "Ooh! You really like my nose, don't you, Chicken?" she said soflty. "Yeah... feels nice." he said in a low tone with a slight shortness of breath. She then brought her left nostril just slightly above over his glans. She then inhaled and exhaled once onto the sensitive flesh of his glans. "I died and gone to Heaven", thought Chicken. Right after this action, his cock twitched again and a bit of precum started coming out of his urethra. She then gently rubbed her nostril on the precum-tipped cock-head. He could see a thin strand of his precum clinging to the side of her nasal cavity. "Want me to put it in my big nose, big brudder?" she asked. "Yes... Yes, please!" he said in an excited half-whisper. "Mmmmm... Your... pecker... is quite big, big brudder. But i know my nose can take it. It can take... aaaaall of your penis... inside of it." she said as her voice lowered to a seductive whisper. She was corect. Her nostrils were quite big. Much bigger than any human's. But Chicken's cock was quite thick. And failry long. She could see that it ended a few inches above his belly-button. She thought how lucky any girl that received that inside her would be. Including her. It would fit into her nostrils with some difficulty, it seemed. And it would give them a bit of a stretching. She lowered her left nostril onto his dick. It enveloped most of his glans. She then slowly pushed her snout down onto his cock. His precum and the small amount of mucus in her nose helped speed up the process a little. She kept pushing down until he was balls-deep inside, the ring of the nostril touching the upper part of the skin of his scrotum. And she still had room to spare. The flesh inside inside felt slightly warm and wet. "Ta-daaaaa! See, Chicken? It fits. Told you." Cow said in a slightly nasally voice. He could hardly believe it. His dick was in his sister's nose. Cow was a little surprised herself. As unusual as this was, they both knew it was wrong. But this fact is what Cow found exciting about the situation. To a lesser extent, so did Chicken. But it would not stop either of them. Not one bit. Cow gently cupped his balls. She started inhaling and exhaling from her nose. During the exhalation, he felt the walls of the nostril hold onto his member less tightly as a rush of air enveloped it instead. During inhalationn he felt her nasal passage clamp down onto his cock. She then used two fingers to push her other nostril closed and then inhaled as she lifted her head, slowly pulling her nostril off his penis. It left his glans with a loud "pop" sound, followed by a small snort. She sucked in some of his precum and swallowed it. She then put that same nose-hole back onto his cock and inhaled. The recently-stretched passage and the rushing air made this return trip go much faster. Chicken was in the grip of ecstasy. He couldn't help but start slowly thrusting in and out even before her nostril was up to his balls. He was getting quite close to cumming. "Oh! Getting impatient, i see. I think you should take care of movement. I'll handle the rest." Cow said. Chicken moved from a sitting position on the couch to a kneeling position with his cock still in his sister's nose. He grabbed the back of her head and neck with his hands and started thrusting in and out of her nostril. He kept a moderate speed at first and then started fucking faster. "Mooooo... My big brudder is having sex with my nostril. You like that, Chicken?" Cow said. "Oooooh... Aaaaw... Yeah. Soooo good. Am i... too rough, Cow?" Chicken said, breathing heavily while fucking. "Oh. No, don't worry. You can be as rough as you want with my nostrils. Enjoy yourself. "Go with the flow", as they say." Cow replied. He was fucking her nose-hole with wild abandon now, going fast and deep. After less than a minute of this, he was feeling like he was about to blow. "Ooooh... Cow... I'm gonna..." Chicken said, overwhelmed by pleasure. "Yes! Yes, big brudder. Give me your "chicken milk". Squirt it all in my nostril. Mooooooo..." Cow said enthusiastically. With her words of encouragement, he came in her nose. Quick, high-pressure spurts of his thick cum shot into her nostril. His hands were gripping her tightly as his thrusts became more like spasms. He was certain he never came that hard before. She was starting to feel her nasal passage filling up. During his last few weaker spurts, she felt his semen drip into her throat. She gladly swallowed it. When he was done ejaculating, Chicken kept his legs tense. As he slowly relaxed them, he was gently caressing the back of her head. He gave out along, soft moan. "I'm so happy you liked that, Chicken. Ooh, you gave me so much thick boy-milk." Cow said soflty. She slowly took her nostril off his softening wet cock, gently inhaling so as to not lose any of her brother's spunk. When she removed her nose from the cock completely, it flopped forward limply, very wet but with barely a drop of cum on it. Most of his seed was in her nose. She snorted loudly and gulped down all of it. She found that it did not have much taste. What taste it did have was quite vague. But she loved where it came from and swallowing it felt very intimate. Chicken sat on the couch with his eyes half-open, doing nothing. In that momemnt, he wanted nothing. Cow sat down on the couch next to him and put an arm around his shoulders, slowly caressing him. The power came back on during their session. After a few minutes cuddling with him, she turned it on and they watched TV together. Later, close to midnight, Cow brought her milking machine, put it on the table and started putting the transparent pumps on her teats. "I didn't get to milk myself much today. We got a little... carried away. You mind if i do it here, Chicken?" Cow asked. "Nah. No prob." Chicken replied. " She turned the machine on. Chicken watched as the pumps sucked on her teats. He saw the milk spray out of them, splashing on the top of the inside of the pumps and get sucked in. He was mesmerized by this process. And starting to get aroused. Cow started mooing softly. She caressed the sides of her udder and then started gently squeezing her udder in a rythmic fashion. She was lightly pleasuring herself and didn't care that her brother was watching. In fact, she wanted him to see this. This erotic display made his penis become erect. She noticed that. But this time, he did not try to hide it. They were both becoming quite at ease around each other. Chicken turned down the volume on the TV. "Hey, uh, Cow? You mind if i?" Chicken said and then started slowly masturbating. "Ooh... You like what you see. I don't mind, sweet brudder. But... I have something else you could do." Cow said. "Oh?" he said. She turned off the machine, then took off one of the cups and moved it over to him, touching the side of his hard cock. "Wanna try... milking yourself with one of these?" she asked. "Well... sure. I just hope it fits." he said. He put a cup over his hard dick and found out that it did. Barely. The cups on Cow's machine were wider and taller than most. It fit over the entire length of his penis and still left a little bit of room between the end of the cup and the tip of his glans. In terms of width, it was a bit of a tight fit, but the milk left behind in it ensured his member slid in fairly easily. "Ready, Chicken?" Cow said. "Yup. Start me up." Chicken said. She flipped the on switch. He felt the cups tighten around the base of his shaft and felt his penis being pulled and tugged. It was sucking on him rithmically. And between sucks, it was "vaccuming" on his cock at slightly a lower intensity. It was a uniquely pleasurable experience. His cock was throbbing and his glans was becoming redder. "That looks nice. Your biiiiig... cock is being sucked like a biiiig teat. It looks... beautiful. You like it, Chicken? Does it feel good? Do you mind me asking you these questions?" Cow said. "Oooooh... Not at all, Cow. It feels so gooood... suckin'... and tuggin' on my... dick... Aaaah..." Chicken said with shortness of breath. It was an intense experience. The cup squeezing and pulling on his aching, hard cock. Every ounce of precum he was leaking was being sucked into the tube. He gripped the sofa with his hands. Cow came closer to him and put her left hand around his waist. She started fondling his testicles with her right hand. She wondered if his "milk" was stored in those "plums" of his. She only vaguely remembered what her anatomy textbook told her about this subject. At the same time, she was receiving pleasure from the cups on three of her teats. And watching her brother 's cock and hearing his moeaning and panting was really turning her on. She started rubbing her pussy with her right hand. "Oh, Chicken. Our... hot milk will be mixing inside the machine. After we're done... i'm gonna drink it all. Oh... Just thinking about it... makes me wet. Mooooooo..." Cow said, also breathing heavily now. Chicken was now starting to thrust slowly into the air, almost involuntarily. He was getting close to ejaculating again. So was Cow, as she kept rubbing her wet pussy. Looking at his dick, Chicken was almost certain his glans had become bigger. It was cramped inside the cup. The discomfort did very little to lessen the immense pleasure he felt. He also started squeezing her uncovered teat. He tried aiming for the bowl that was next to the tubes, but alot of the milk missed its mark. Neither of them particularly cared. After about a minute of bliss, Chicken tensed up all over and ejaculated. Even after cumming before, he still had plenty left. Every spurt of cum was sucked into the tube attached to the cup. The viscosity of his orgasm-juice made it so that it was sucked up slower. It violently splashed onto the top of the cup, coating it with his hot, sticky "milk". Even after he stopped squirting, the machine still sucked up every drop of cum from his urethra. And after her was completely dry, it kept sucking. Seeing her brother ejaculate pushed Cow over the edge, squirting her own clear orgasmic fluid onto the sofa, the floor and the underside of her udder. Then, with a shaky hand, she turned the machine off. They both stood there, breathing heavily with their eyes closed. After a while, Cow grabbed the pack of cigarettes she left on the table and lit herself a cigarette. She then gave one to Chicken and lit it. They tasted much better than before after that experience. After they done smoking, Cow removed the cups and hungrily gulped down the accumulated milk and semen from the container in the machine. She wished she could taste his cum more clearly. After that, Chicken turned off the TV and started walking with trembling legs up the stairs to their room. Cow instead decided to pick him up and carry him lovingly in her arms up the stairs. She put him in his bed, put his blanket over and kissed him tenderly on the mouth. "Sweet dreams, big brother. We shall have more fun tommorow." Cow said softly before climbing into her own bed. They both slept soundly.
