Chicken woke up the next morning feeling happy and refreshed. He saw that Cow was now in her top bunk. He went downstairs to the kitchen and saw that there was a plate containing two fried eggs and toast. Cow was just finishing preparaing her own meal containing the same. She put her eggs on a plate and turned around to see Chicken. A small smile formed on her face

"Good morning, Chickeeeeen!" she said happilly.

She put her plate on a table, then put an empty glass next to Chicken's plate. She then gave Chicken a big kiss on the side of his face.

"Oh, I almost forgot." Cow said.

She tilted the glass diagonally and squeezed one of her teats, filling it with milk.

"Fresh from the tap. Bone apettite!" she said.

Chicken had woken up with an erection. It was at half-mast by the time he saw her. Seeing her squeeze milk out of her udder made his penis rise fully once more. He walked over to her and gave her a big hug. His head on her stomach. His small body was touching the left side of her udder.

"Mornin', sis." Chicken said.

Cow hugged him back and caressed his back. Chicken then started groping and caressing her udder and buttocks. His cock was pressed against the base of her udder and was twitching.

"Oooooh, Chicken... You're being a very naughty boy. Touching your little sister like that. So... lewd! You're lucky she likes it. A-hoo-hoo-hoo!" Cow flirtingly said.

Chicken then started rubbing his penis on her udder between the upper left teat and the other three teats while continuing to grope her udder. Cow was getting very aroused. She imagined herself pushing him down on the ground, then getting on top of him and vigourously rubbing her udder up and down the length of his cock, followed by her squirting milk on his dick, then jumping on his manhood and riding him hard like a sexy cowgirl. But she had to stop herself from taking it any further for now. Him as well. She gently placed a hand on his stomach to prevent him from moving.

"Oh, Chicken... I want this. Alot. But... not now. We need to wait until later. When we're fully... recharged. When we have plenty of... milk... to give to each other. Tonight." Cow said tenderly while caressing his comb.

"Aaaaaaaw... OK. You promise?" Chicken said, dissapointed.

Cow kissed his mouth tenderly and said:

"I promise. Now let's eat breakfast. The eggs are getting cold."

Later that day, long after eating dinner and after the sun set, Cow and Chicken were standing on the sofa, watching TV. Cow felt a pressure in her engorged milk-filled breasts. It hurt a bit, but it also felt good. Her aching udder made her feel horny. She felt it was now the right time to get herself milked. Same for her brother. 

Slowly, she got closer to her brother on the sofa, whose eyes were focused on the screen. When she got right next to him, she started tenderly kissing the side of his face and caressing his  chest. Chicken started reciprocating and kissed her on the mouth. Cow then put an arm around his back. She picked up the remote control with the other and turned the television off while still lovingly spooning with her brother. Chicken then hugged with both arms. After this, she started slowly french-kissing him. Cow's warm udder was right on top of Chicken's crotch. She felt his penis emerge and rub past her udder as it became erect.  Their breathing was getting heavier.

"Oh, Chicken. My udder... feels so full. It needs... relief. Will you please help me? Will you milk it... slow... and hard? WIll you... let me milk you... big brudder?" Cow said soflty, kissing Chicken as she did.

"Oh, yeah, Cow. Yeah... I want you... I want you so bad right now. I'll milk you, sis. Oh, i am going milk you as much as you want, Cow. Gonna milk you... hard. You gonna milk me too?" Chicken said, every second or third word of his punctuated by him kissing his sister.

"I certainly will, Chicken. But first, let's go somewhere where we can make as much of a mess as we want. The bathroom." Cow said.

Cow picked him up in her arms and took him into the bathroom as Chicken soflty kissed the side of her neck. Once there, she placed him on a rug. A drain was conveniently located nearby. She then embraced him and he rubbed his hard cock against her udder while running his open palms against its sides and groping it as he did. They were both standing and sharing a long kiss while this happened. He squeezed fairly hard on her two uppermost teats and pulled slightly. Milk sprayed from them, landing just above his thighs and running down his legs. Cow broke the kiss and let out a sigh of pleasure followed by a moo.

"Moooooooo... Ooh, it feels so good when you play with my big, sensitive udder and teats." Cow said.

"Can i... ask you to do somethin' for me, sis?" Chicken said in almost a whisper.

"Anything, my playful big brudder. Anything you want." Cow said, seductively.

She rubbed her udder on his twitching cock from left to right as she said this. It left small amounts of milk on his cock and legs.

"I want you to... squirt some milk... on my dick." he said.

He took a step back from her and started rubbing his cock. Cow had a very lustful and seductive expression as she rubbed her udder with her hands and briefly shook it up and down. She grabbed the base of her upper-right teat, aimed it at his cock, then squeezed and pulled on it hard. A high-pressure stream of milk blasted his cock. It hit the lower part of his glans, right in the center. She squeezed again and the next stream hit the top of the glans, slightly to the left. Milk ran down his cock and balls and on the floor as he was masturbating. Precum started leaking out of his urethra. Chicken moaned in pleasure. It felt amazing. The rough treatment she gave to her teats was making Cow enjoy it too. She mooed softly with every squirt. Her arousal was making her pussy wet.

"Oh, yeah! Like that. Please... Squirt more milk, Cow." Chicken said while vigorously jacking off his slick, milk-covered cock.

Cow put her hands on the sides of her udder and squeezed hard. Milk furiously rushed forth from all of her teats, drenching her brother's crotch and belly area.

"Ooooooh... oh yeah... just like that Cow. Feels... so good. Now... squirt that warm milk... aaaaall over me." Chicken said, breathing heavily.

Chicken opened his mouth and put out his tongue, still masturbating. Cow squeezed again, getting the entire front of Chicken's body wet with her milk. A large amount went into his mouth, which he hungrily swallowed. She then repeated this action once more. Chicken walked closer to Cow. He was feeling himself get close to cumming. He got close enough that his glans was touching one of her teats. Precum from his cock leaked onto it and mixed with the small amount of milk left on it. His cock was now touching the center of her udders. He took his hand of it and rubbed it against the udder. He was also squeezing the upper teats hard and pulling on them, large amounts of milk shooting out of them as he did. It drove Cow wild. She was squeezing her udder with her lef thand and with the right she was pulling on the lower-right teat in an upward direction, shooting milk onto Chicken's balls. She was close to her limit as well.

"Oh yes! Yes, big brudder! Milk me! Milk me hard! Feels so good! Oh... I'm going to... Dyooooooooooooooooh! Ah! Mooooooooooooooo!" Cow said while her orgasm erupted.

Her pussy let forth a stream of clear high-pressure orgasmic fluid, which mixed with the milk on the floor, both then going down the drain. Chicken also ejaculated about a second after Cow started squirting. Thick ropes of cum shot upwards from his cock and landed ontop of Cow's udder and on her belly. After the first two spurts, he pushed his crotch into her udder, burrying his gushing cock under the soft flesh of her mammary tank, causing it to shoot milk once more. His cum now only shot onto the front of her udder and his own member. He kept his cock there until he was finished cumming. Cum leaked down the front of her udder and his balls. They both stood there afterward, with eyes closed, heavy breath and trembling legs. They stood like this for more than a minute, before sitting down on the rug, still feeling exhausted. After a while, she started licking the cum and milk from her udder while still sitting down. To top it off, she opened her mouth wide and placed her big mouth on the entire udder, sucking it clean.

But Cow wanted more. She wanted Chicken to do womething for her this time.

"Chicken? Can you do something for me? Please?" Cow asked him.

"Of course, sis. Whatever you want. You've been so good to me. Made me feel so nice. I'll whatever you want. Just say the word." Chicken said.

Cow stood up and lifted her udder, revealing her shapely thighs and wet pussy.

"Ever seen one of these before, Chicken? It's my... special place. All girls have one. It feels good when they... touch it. I want you to... give it kisses. Lots of soft kisses? Please?" Cow said.

"Woah. Is that a... vagina? Looks... nice. Sure. I've seen one before. In a magazine. I've been kinda curious to know what it tastes like." Chicken said.

She got on her back and he started kissing her pussy. First the sides of the labia and then between the pussy lips. He then started licking the inside, his tongue going in and out in a shallow fashion, tasting the vaguely-sweet fluid leaking from within. Then he started kissing and licking the clitoris and urethra. Cow's legs were squirming. She put them on Chicken's back. She urged him to put his beak inside her pussy. She gaped her pussy open, giving him a good view of the wet, pink flesh inside. She no longer had a hymen. This was the result of her ocasionally using her mother's dildo on herself. She always made sure to clean it and put it back where she found it after she was done with it. Chicken inserted his beak inside her and she  locked her legs around his head, pushing his beak deeper while she caressed his comb. His penis became erect and he was rubbing it slowly while he worked on orally stimulating his sister. He beak-fucked and licked deep inside her pussy until Cow felt she was close and told him to put his mouth on her urethra. She wanted him to drink her gushing love-fountain. She soon squirted inside his mouth and he eagerly drank all that she offered him. Her legs squeezed tight around his head until she was done spraying. After less than a minute of ater-glow, she was ready for more. And so was Chicken. She stood up, slowly pushed him down. Chicken was now with his back against the floor. Cow was above him, her pussy above his hard cock. She lifted her udder again and grabbed his cock, raising it to a vertical position. It was now touching her pussy.

"This is a special moment, big brudder. I'm going to take your virginity. Are you ready?" Cow said.

"I've never been more ready in my life. I want in there. Bad." Chicken said.

"Ooh, Hee-hee-hoo-hoo! Here it cooooomes." Cow said, saying that last word in a semi-melodic tone.

She slowly lowered herself onto his cock until the glans was eneveloped by her pussy. She had never taken anything this big inside her before. But now, she got a measure of his cock would fit inside her. She knew she would barely have any trouble. And so she suddenly lowered herself down completely. She took his entire length in her pussy. The tip was lightly touching her cervix. Chicken felt the warm and wet softness of her birth canal envelop his cock. It felt amazing. His penis throbbed in appreciation. Cow adored how full his big cock made her pussy feel.

"Oh! It's in! Oh, Chicken. Your penis is inside... my vagina. It fits like a glove. It feels so big... so good. Moooooo..." Cow said enthusiastically.

"Oh, yeah. Wow. I'm... I'm actually havin'... sex. With my sister.

In that moment, Chicken felt like he had become a man. And Cow felt like she had become a woman. She started riding him. Raising herself up and down on his cock, while her udder rested on Chicken belly, which he groped and caressed. She felt sexy. She felt in charge. She felt like an iresistible seductress, freely giving and receiving pleasure from her lover. Before this weekend, she believed that few boys, if any, would find her attractive due to her unusual physical features. The fact that she lacked the breasts that the other girls and women around had made her feel inadequate. But those feelings disappeared since the moment she found out for certain that at least one boy found her udder to be sexy. And the rest of her. Feeling wanted made her feel happy. And horny. 

Chicken grabbed her butt-cheeks and started thrusting by himself. He was slowly picking up speed. Very soon, he was thrusting hard and deep into her, slamming against her cervix. His enthustiastic penetration and rough handling of her udder was pushing her over the edge and soon, she orgasmed, drenching her brother's crotch in her love-juice.

"Cow? Can i... switch position? I wanna... drink your milk... while i'm having sex with you." Chicken said.

"Of course, Chicken." she said.

She got off him, laid on her back and spread her legs.

"Like thiiiiis?" she asked.

"Yeah. Just like that." Chicken said as he kneeled down between her legs.

He inserted himself into her again and started thrusting into her wet womanhood again while putting an arm around her udder and wrapping his mouth around her teats, drinking deep from each one. If she was not suficiently relieved of milk before, she definitely would be when he was done.

"Oh yes, big brudder. Fuck me! Fuck your little sister's pussy with your biiiig, hard cock! Like that! Ravage me, Chicken! Fill my pussy with your semen!" Cow said enthusiastically.

She felt so naughty saying all those obscene words to him. But neither of them felt any shame anymore as brother and sister consumated their lust for eachother.

 Having already ejaculated once before, Chicken could last much longer now. The long and rough sustained onslaught of his thrusting and teat-sucking made her orgasm twice more before he did. When he finally came, he kept his cock on her cervix. As his cock squirted out the last load of his semen for that day, his thrusting became short and jerky as he blasted Cow's cervix with his seed. Some of it pushed past the opening and entered her uterus. He gripped tightly onto her udder each time he squirted cum. The total volume was almost as much as when he used her milking machine on himself, but here it felt even more fulsilling. Her teats were now releasing thin streams of milk and her udder looked somewhat deflated. When his orgasm finally subsided, he lay on top of her. They were both drained, exhausted and fully satisfied.

When they finally got up, they both walked together up the stairs to their room. Their legs were shaking with each step. They reached the bunk bed and Cow asked for one more request.

"I want to sleep next to you, my loving big brudder? Please?" she said.

Chicken said nothing. Instead he got into the lower bed and beckoned Cow with a hand gesture. She got in next to him. They kissed and cuddled until they fell asleep in each other's arms, more at peace than they had ever felt before.
