Sister's Milk

Sister's Milk

Mike cursed as his car swerved slightly. He wish he could have gotten some snow tires... maybe he could convince his mom to lend him some money. He would really have to play up how dangerous this trip had been for him.

Snowflakes twirled out infinitely ahead of him. It didn't even look like they were falling, but rather like he was driving through some weird swirling snow cyclone. The highway wasn't completely covered in snow, but there was enough to make it slippery and treacherous.

Every year Mike still drove down to stay with his mom and sister for the week of Christmas. This year, Mike was anxious to arrive. While the trip was a nice family tradition, Mike was on a mission. Something weird was going on with his sister, Jennifer. His Mom, Charlene, had tried to tell him about it but she had been oddly vague. Apparently there was some kind of odd health issue and it was keeping Jennifer home from college. Charlene had said it was too personal to share any details about, so Mike knew the only way he'd find out more was if he saw his sister in person.

Despite assurances from his mom that Jennifer was not in danger, Mike couldn't help but speculate what awful disease she must have that in spoiled her plans to become a teacher. She had missed the spring and fall semesters already, and it didn't sound like she planned on returning in the winter either. She must be really sick, whatever it is.

Could she be pregnant? If that was the case, surely she would have told him. Mike felt like his mom would have shared this, they were a pretty progressive family and none of them would have judge Jennifer for getting knocked up.

Mike let out an exasperated sigh. Whatever it was, he was about an hour away from home, and he would find out soon.

Mike pulled into his mother's driveway and got out of the car. He went to the back of the car and got his bags, and a box of Christmas gifts out of the trunk and started up the snowy walk to the house. He was anxious and nervous as he rang the doorbell and waited. After a few moments, Charlene opened the door with a big smile.

Charlene was short, her head barely came up to Mike's chest. She was a curvy, with wide hips and a large butt. Her bust was quite large. Jenny used to complain all the time about how mom had such big boobs and she didn't, even though she took after mom in most other ways. These discussions always embarrassed and frustrated Mike, not wanting the think about his mom or his sister that way. Yet he often found his mind wandering in that direction... like now.

"Mikey!"

Charlene smiled wide as she rushed towards her son. Her reddish hair was styled up in a messy bun and she was wearing a thick knit sweater and some tight leggings. She looked amazing for her age. She grabbed onto Mike's arm.

"Mike! Come in come in! Missed you so much sweetie!" she said as she pulled him into the house and hugged him.

"Hey Mom, missed you too," he said as he hugged her back for a moment before breaking it off, "is Jenny home?"

Charlene's expression morphed into a pained smile.

"Mike, Jenny can't really leave the house much these days. She's in her room. I'm sure she'd be happy to see you..." she said. Mike, having removed his coat and boots, put his stuff down and started towards his sister's room.

"Mikey!" Charlene said suddenly, "Make sure to knock!"

Mike looked back at his mom: she looked very anxious. She was clearly trying to act as normal as possible, but having some trouble keeping that up. Mike wondered what was concerning her. He turned back and made his way to his sister's room. He knocked at the door.

"Jenny? Its Mike... I'm uh... back for the holi...days..."

While Mike spoke he heard a sudden ruckus. It sounded like Jennifer was knocking furniture over and slamming things shut. Mike was intrigued by the sounds, but stood his ground and waited. After an awkward amount of time Mike heard her call out, sounding kind of frazzled.

"Hey- hey Mike! Uh... come in!"

Mike opened the door and scanned the room before settling on his sister, sitting up in her bed with her back against the headboard. The room looked... kind of normal. There were some small changes: a new desk with a computer, presumably for college, some books laying about, mini fridge... nothing to crazy. Jennifer's reddish brown hair was down but mussed. Her pretty green eyes were fixed on Mike, examining him closely. A nervous, but friendly smile on her lips. Mike wondered for a moment if she was not dressed, the way she was holding the covers over herself, but he could make out the shoulder straps of a tank top. Mike decided not to press and entered her room, sitting down at her desk chair at the foot of her bed.

"Hey Jenny. How uh... how are things going?"

Her face reddened slightly in embarrassment. She sort of stuttered nervously through her response, "I'm... I'm alright. All things... considered and all... you know." She seemed off to Mike. Mike remembered Jenny as a teasing, confident little sister. It was more on brand for her to taunt and joke-flirt with him a little, just to try and make him uncomfortable. Or to parade around the house half naked and ask Mike if he liked what he saw when he was obviously embarrassed to see her like that. Seeing her meek, bashful, and really obviously trying to hide her body caused his curiosity to skyrocket.

"How was the drive in?" she asked suddenly, "I heard the roads were really bad because of the snow."

"Yeah it was slippery as fuck. I almost skidded off the road a few times."

"Jeez... well I'm uh... I'm glad you didn't..." she said nervously. Mike cocked his head, puzzling at her behaviour. She wasn't usually so awkward. She continued after a moment, "I can't... I haven't really been out much lately."

Mike nodded, as if she was making any sense. He stood up, wanting to leave her room and dispel this bizarre tension.

"Well, you seem tired or something, so I'll leave you alone. It's good seeing you Jenny, I hope you feel better soon."

With that he walked up to the head of the bed and bent over to give her a little half hug. She seemed to gasp slightly as he put his arm around her shoulder and leaned his head against hers. When he pulled away he saw that she looked flushed.

"Let me know if there's any way I can help with... whatever you're going through. Love ya, lil sis."

Her face lit up for a second and Mike almost thought she was going to say something, but instead she just blushed some more and thanked him. Mike left her room no less puzzled than when he walked in. She hadn't looked sickly, but she was clearly not herself. She had acted so bizarre, it was so out of character for her. It was like she was an entirely different person. Maybe it was some hormone thing? She had been covering herself awkwardly with the blankets, so Mike wasn't able to tell if she was pregnant. Maybe she had been disfigured somehow? But surely mom would have mentioned an accident or assault.

As Mike walked back into the dining room he saw his mom setting three spots at the table. She looked up at Mike as he walked in, clearly trying to get a read on him. Mike, impatient with the sustained mysteriousness that seemed to have enveloped his family walked up to Charlene.

"Mom. What is going on with Jenny."

Charlene froze for a moment before continuing to set the table. She looked up at Mike, clearly a little confused.

"Didn't you just see her?" she asked.

"Yeah, and she was acting very... weird."

"Acting weird? You... didn't notice anything else?" she asked with an incredulous look on her face.

"Well she was in bed and held the covers up the whole time so if she's got a second torso or something now I wasn't able to tell."

Charlene's expression changed from confusion to understanding to taciturn.

"Ah. Well, its not my place to share with you what she clearly isn't ready to yet."

"So the plan is that we're all having dinner together though? You're setting three spots. Is she going to sit at the table with a table cloth over her or what?"

"Mike, you're being unbelievably insensitive right now. I'm sure you'll learn about your sister's condition soon enough. For now, afford her the respect to chose when another person should get to learn about this very personal part of her life. I set three spots in hopes she would come down for dinner. If she doesn't feel up to joining us, I'll bring her food to her room as I sometimes do. Now, stop pestering me and go get settled in."

With that she walked off to the kitchen. Mike felt a hot wash of shame as he wordlessly gathered his stuff from the entrance and went to go get set up in his childhood room.

As Mike finished putting his things in order, he heard a soft knock on the door.

"Yes? Come in." he said, expecting his mother. The door opened a crack.

"Hey Mikey, I wanted to... explain..."

Mike turned and was shocked to see his sister, and then almost had a heart attack. Jenny was standing there in a tank top and shorts. Mike couldn't believe what he was seeing: her breasts were... enormous. Much bigger than he remembered. Much bigger than moms. Much bigger than he had ever seen before, especially on such a slender frame.

"Whoa!" Mike said involuntarily. Jenny's face turned bright red, and for a moment it looked like she was going to leave, but she seemed to steel herself and stood her ground.

"Yeah they're... pretty noticeable."

"Is that... is that what's been keeping you out of school?" Mike asked incredulously. He couldn't stop his eyes from darting back to her tits, even moments after he would tear them away to look his sister in the face. She was clearly wearing no bra. Little tents in the cotton were visible where her nipples protruded. As she stood there, slight movements cause them to jiggle and wobble very enticingly. Mike wondered what they felt like, they looked so soft. Mike tried to shake these thoughts from his head but they kept coming back. His eyes darted all over Jennifer's body, taking in her slender waist, her wide hips, her huge boobs...

"H-how?" he asked. She averted her eyes.

"This... they're just a side affect of the actual issue. I wouldn't just drop out of school cause my tits got big. Even if they are a little on the ridiculous side-"

"They're not ridiculous, they look good- uhh you look good I mean." Mike said unexpectedly, feeling his own face start to turn red. He felt a sinking feeling in the pit of his stomach. He had just complimented his sister's tits. To her face. What the hell was wrong with him?

Jennifer looked shocked for a moment. She stared at Mike for a moment with an indecipherable look on her face. After a long pause, she continued.

"Ah uh, thanks", she said as she managed to blush again, "I'm glad you... um anyway. What I was trying to say was that the reason my boobs have grown so much is because I have this weird medical condition. I um... lactate."

Mike's eyes widened. He couldn't believe what he was hearing.

"You lactate? You mean like... milk?" he asked, feeling himself getting oddly aroused. He hoped his growing erection wasn't visible...

"Yeah my boobs make milk. Like, a lot. I have to stay home all day and pump them over and over. It's so frustrating!" she said, stomping her foot, making her large chest heave dramatically.

"I can't leave the house because if I leave them alone for too long they start to leak, and it gets everywhere. Plus I need to eat like all the time because my body is diverting all my calories to making this useless milk all day. My doctor gave me a prescription for a drug that's supposed to reduce the lactation and all it did was give me stomach aches, so I stopped taking it. I just sit in my room all day and snack, and then eat dinner with mom. My life is ruined and there's nothing I can do!"

As she finished she was in tears. Mike felt horrible. All of his sister's life goals had been swept away by this weird condition. Would she really have to stay home all the time? Despite the horror of this realization, Mike felt himself continuing to get aroused and he felt awful about it. He walked over to his sister, who was now clearly crying.

"Hey hey hey, its OK Jenny, shhhhh", he whispered to her as he gave her a hug. As he wrapped his arms around her, it was like the floodgates opened for her. She started sobbing, her body convulsing as she melted into Mike's arms and let it all out. He held her tight. He couldn't think of the last time he had given her a hug, but it certainly hadn't been as weird as this one was. As she pressed her body against him he couldn't help but marvel at how soft and pleasantly firm her breasts felt pushed against him. It felt so good to hug her, he felt his hard cock pressing through his sweatpants into her abdomen. As she heaved and sobbed her body rubbed against him and it was really getting him hot. He also, genuinely, felt so bad for her and was trying to help reduce her anguish. He muttered encouragingly in her ear and held her tight. Gave her a kiss on the top of her head and she seemed to tremble a bit. She started to calm down, snivelling and occasionally twitching in his arms.

"Oh Jenny... I'm so sorry this has happened to you. Are you sure you can't leave the house? Couldn't we try... something to absorb the leaks?"

She snivelled a bit and looked up at him. He felt bad as he couldn't help but notice how beautiful she was, and he realized he would probably be replaying this scene, with her wide eyes looking up at him and her incredible cleavage smushed against him, over and over in his mind.

"Yeah", she said, "that works for like, very short amounts of time. And then... I leak through. Plus most of my clothes don't fit me properly: I don't have a winter coat that I can actually close."

"Can't you just order some new stuff online? Like, take your measurements..."

"Mike, don't you think I've tried all that? Yeah I have some stuff that fits, but a lot of the stuff I order I have to send back. And often, it gets ruined by my stupid boobs leaking on the clothes and I don't get refunded. I'm not made of money, especially since I can't work. I have enough clothing to stay mostly decent around the house, but I don't feel comfortable leaving the house dressed like a slut, leaking milk like a cow."

She pushed out of the hug as she said this and looked at Mike accusatorily. After a moment, she softened a bit.

"I appreciate you trying to help, but I've been dealing with this for 6 months now. I know what I can and can't do." she said, more softly.

"Yeah that makes sense, sorry about that." Mike responded, feeling kind of shitty.

"Anyway, I just thought you should know what was going on before you saw me at dinner, or in case you saw me leak through a shirt or something. I'm going back to my room now, I need to pump some more."

As if on queue, a wet spot appeared around her left areola. She made a frustrated sound and hurried out of Mike's room. As she walked away, Mike got a good look at her nice round butt in her short shorts. He closed and locked the door behind her and sat on his bed. This was a lot to process. He got up and fetched his computer, planning on distracting himself from the emotional roller coaster of both feeling sorry for his sister and feeling so lewdly attracted to her. Maybe he would get some work done...

"Mikey! Jenny! Dinner is ready!"

Mike closed his laptop and put his dick back in his pants. After a few hours of trying to distract himself with mundane affairs he broke down and stated looking up lactation porn. And brother-sister incest porn. He had watched the latter before, but his sister had awakened something new in him with her revelation which had caused him to delve into the former. He had started watching a video of a big titted red head breastfeeding a sexy blond when his mom had called up for dinner. Feeling even more worked up, confused and anxious than before, Mike left his room and started walking to the kitchen.

In the hallway he stopped as he heard his sister's door open. She walked out wearing a bright yellow and green sundress. Mike could only see her from behind, but she looked super good in it. It was nice and tight and really flaunted her big butt, wide hips, and slender little waist.

"Hey Jenny, that looks like something you could... wear... out of... the house..." he said as she turned around to look at him, revealing that the dress, which buttoned up at the front, was unbuttoned from the top almost down to her waist. Her breasts pushed the bodice of the dress out so absurdly that it was impossible to imagine it could be buttoned up. As his assertion ran out of steam, Jennifer smirked at him slightly.

"Yeah? I'm sure you're right." she said sarcastically as she turned around and walked down the hall. Mike shook his head and followed her, trying not to watch her nice butt bounce as she walked in front of him.

Dinner was a trying affair. Mike couldn't help staring at his sister's basically bare chest as she sat across from him and pretended to not notice. If Charlene was surprised to see Jennifer dressed so provocatively, she didn't show it. She seemed to be trying her best to make this a normal family dinner, asking the siblings questions about their days and teasing them slightly. There was a weird tension in the air between them though and Charlene could tell. When dinner was over, she receded into the kitchen to clean up.

Mike decided to watch TV in the living room instead of in his room, hoping it would entice his sister and mom to join him. It wouldn't be family time if they all spent it cooped up in their own sections of the house. Jennifer watched him get set up and stood there, kind of awkwardly. Mike turned to her as he sat on the couch.

"Hey, I was going to watch something, want to join?" he asked, trying to sound normal.

Jennifer inhaled sharply and Mike noticed her nipples suddenly make themselves known through her dress. Seeing Mike's eyes move to her bust again, Jennifer blushed deep red.

"That sounds nice Mike, but I really need to go pump..."

"Jenny!" Charlene called out from the kitchen, "Just bring the pump into the living room! I keep telling you that. I even got out that big blanket so you can cover up for modesty!"

Jennifer seemed to hesitate, biting her lip as her eyes darted from Mike back towards her room.

"It wouldn't bother me," Mike said, "it would be nice to hang out. I haven't seen you in so long. Plus we should try and normalize the situation here. Its bad enough you can't leave the house, you should at least feel comfortable here."

"See? Mikey gets it!" Charlene called out. Jennifer looked at Mike for a long moment.

"OK, I'll go grab my stuff." she said, very softly. She walked to her room.

Mike sat on the couch, sweating, trying to will his erection down. Why had he suggested this? Now she was going to pump right next to him on the couch. He just hoped she didn't find out what was going through his head. It was obvious that he had been staring at her tits, he just couldn't bring himself to stop! He wasn't normally one of those guys who objectifies every woman he sees, but for some reason he had no willpower in this scenario. He just couldn't bring himself to look away and keep his eyes off her huge chest.

After a few long minutes Mike wondered if Jennifer was actually going to come back. If she wasn't going to anyway, he was really tempted to go back to his room and finish his pre-dinner activity. He was thinking of what search terms he should try to capture both his milk and sister related fetishes when he heard her door open again and suddenly she was back in the living room, carrying a tote bag and a stand-up TV tray.

She strode over to the couch, looking right at Mike with a weird expression on her face. Mike tried to meet her gaze but her open dress and bouncing breasts won out again and he found himself staring. When she got to the couch, she bent over towards him. Her chest was momentarily thrust towards his face as she reached over him and grabbed the blanket on the other side of him. Mike felt his heart racing as, for one short sweet moment, her huge breasts swung mere centimetres from his face. He noticed a really pleasant, sweet smell emanating from her. Could that be the milk?
