sis’s milk

Sean pulled the rental car to the curb in front of his sister’s house and parked. Pulling a small duffel bag from the back seat, he started up the walkway to the front porch.

He hadn’t seen Cynthia in a little over six months, and the last time he’d seen her, she had looked as though she’d swallowed a basketball. A month later, Cyn had given birth to Lisa, his first niece.

Let’s see, he thought, that would make Lisa about five months old, now!

He should have made it back to see his niece earlier, but living on the opposite coast made the trip an expensive one. And he’d used the last of that year’s vacation days on his last trip home. Thankfully, the new year had brought a new batch of vacation days, and he’d managed to Sean this trip to let him kill several birds with one stone: visit with his parents, visit his sister and see his niece for the first time, and also attend his best friend’s wedding. A side benefit was that he’d be able to help Cyn paint her husband’s den while he was away on a business trip. She was sure that Tom would be surprised by the renovation, when he returned home.

Stepping up to the door, he rang the doorbell and heard Cynthia’s voice through the screen door, inviting him to come in.

Pushing the door open, he stepped into the foyer.

“Cyn?” he called out.

“I’m here, in the living room,” she responded loudly.

“Uh, okay,” he said walking toward the sound of her voice.

Stepping into the living room, he stopped dead in his tracks, staring at his sister sitting on the couch. Sitting on the couch…nursing Lisa. With her blouse completely unbuttoned and both of her huge breasts bared.

Sean’s eyes flared open and his chin dropped as he stared at his sister. She had Lisa’s mouth pressed against one of her big, beautiful breasts as she sat lovingly looking down at her baby. Little Lisa was holding onto the huge, milk-filled udder with her tiny hands, hungrily sucking away at the nipple as Sean looked on in fascination.

Then, Cynthia looked up and saw him staring at her with a shocked look on his face.

“Oops…sorry…I forgot,” she laughed, draping her shirt over her breasts, covering one and partially covering the other, from Sean’s peering stare.

“Uh…uh…that’s…that’s okay,” he said, trying to swallow the bale of cotton that had mysteriously appeared in his mouth as he tried to calm the stirring he felt down in his jeans. “I…I just wasn’t expecting that. They…They’re so big.

“Yeah, that’s what happens when you’ve got a kid to feed,” she smiled up at him.

“Really big,” he muttered.

“I’ve got everything set up in the den, if you want to go ahead and start. Let me just finish nursing Lisa, and I’ll be in to help you in a few minutes.”

“Okay,” he said, taking another quick glance at her partially exposed breast as he set his overnighter on the coffee table.

He couldn’t believe how big her tits were. The only time he had seen them before was when they were kids. They were tiny, back then.

“Uh, the den,” he nodded, finally tearing his eyes away from his sister’s breast as he saw a slight blush color her cheeks.

“Sorry,” he apologized, blushing himself as he turned and started for the den.

“That’s okay,” she called after him, “It’s my fault, really. I should have nursed her earlier.”

Sean had arrived in his painting clothes, so he had finished one wall and was starting on a second before Cynthia came strolling into the room. He looked away from his task to see that she was wearing only an old paint-splattered shirt and panties. The hem of the shirt hung down in the front and back, obscuring most of the view, but the shirt arched up in a curve on the sides, revealing the waistband of her panties where it crossed her rounded hips. The shirt was also thin enough for him to note that she wasn’t wearing a bra. Even if the pendulous swing of her breasts wasn’t noticeable — which it definitely was — her nipples, still erect from the sSeanulus of nursing, were poking blatantly against the worn fabric.

“Sorry, I took so long, but I wanted to put Lisa to bed so we wouldn’t be interrupted,” she told him. “You can get to know her tomorrow.”

“Yeah, that’d be nice,” he smiled, glancing down at the exposed cleavage peeking out from between the edges of her shirt and her thrusting breasts. “I got a lot done anyway.”

“Yeah, I see. I’ll help you do another wall, then I’ll start on the trim,” she said, ignoring his prying look as she bent down and picked up her roller and paint tray. “I’ve ordered a pizza delivery, for dinner.”

“You sure look nice, Sis,” he told her. “You look a lot different than you did the last time I saw you.”

“A half-hour on the treadmill, every day,” she said, feigning wiping sweat from her forehead. “It’ll keep you fit and trim.”

“Well, I must admit, it seems to be working,” he smiled.

“Why, thank you,” she laughed softly, noting the slight blush coloring her cheeks.

Watching his sister move about with her giant, milk-laden breasts undulating heavily under the shirt soon had Sean in a highly obvious state of arousal. He tried his best to keep it hidden by facing away from her while he painted.

Two hours of steady work had the walls and trim covered in new paint. The pizza arrived and they devoured it quickly. Their intended return to painting was delayed, however, when Lisa awoke from her nap and announced — with a loud wail — that she needed some attention.

Motioning for Sean to follow her, Cynthia led the way to the nursery. Lifting her infant daughter from the crib, she placed her in her uncle’s unsure arms.

“Relax, honey,” she giggled when Sean looked up at her with somewhat terrified eyes. “You can do it; it’s instinctive. And it’ll be good practice, for when you finally have a wife and baby of your own!”

“Oh — you mean this look on my face?” Sean shook his head. “It isn’t fear. It’s more like lack of knowing what to do. I can smell it, even if you can’t. I think she needs a change of diapers.”

“Then we’ll give you a bit more practice,” Cyn laughed. “Put her over there, on the bassinette, and I’ll get the baby-wipes.”

With Cynthia looking on with an amused grin, Sean followed her instructions and handled the diaper-change rather well, all things considered.

Then, of course, he had to endure the sight of her partially-exposed breast, again, as Cynthia nursed Lisa before putting her back to bed for the night.

Shortly, the nursing was finished, and Cynthia buttoned the blouse again, though Sean noticed one less button was fastened than earlier, and they returned to their task of painting. An hour later, they were finally finished and stood looking around at their handiwork.

“Looks great,” Cynthia beamed, looking over at him. “We make a great team…”

“Yeah, maybe we ought to set up a business,” he laughed. “But first, I think you’d better clean up. You look like you’ve got green measles.”

“Aren’t you the pot, to call the kettle black,” she laughed back at him, running a fingertip down his paint-splattered cheek.

Impulsively, Sean grabbed her hand and brought her finger to his lips. Holding it gently pressed against them, he gave the tip of her finger a lingering kiss.

Questioningly, she looked into his eyes, her cheeks flushing once again. Then he smiled and let go of her hand.

“Why did you do that?” she asked.

“I don’t know,” he smiled. “I don’t know…it just seemed like the thing to do at the moment. Sorry if it upset you…”

“No, no, it’s okay,” she said, taking a step back as her big tits swayed ponderously under her shirt. “It just took me by surprise…that’s all. It was a sweet thing to do.”

“Well, who’s first? You or me?” he asked, stepping back over to the paint buckets.

“What do you mean?” she asked, with a puzzled look on her face.

“You or me…the shower?” he said, leaning down and dropping his brush into a bucket of water.

“You, you, I guess. Yeah, you can go first,” she said, following him over to the buckets. “I’ll clean up this mess while you go clean yourself up.”

“Okay,” he grinned, standing up and departing toward the bathroom.

Grabbing his overnighter on the way, he hurried down the hall to the bath.

Showering, he was torn between whacking off to get rid of his obvious erection or saving it for later, when he was in bed. Finally, after a few strokes, he decided to do it later, after Cynthia went to bed. With a grimace, he turned on the cold water and stood under it until his cock finally began cooperating and wilted back down to a much more manageable size…

Once he was dried off, he quickly slipped his pajamas and slippers on before heading back out to the living room. Stepping into the living room, he saw that Cynthia was sitting on the couch waiting for him. She had made a fire in the fireplace and had a bottle of wine sitting on the coffee table. Beside the wine sat two glasses. One empty and the other, half full.

“I thought maybe you’d drowned or something,” she laughed softly, getting up from the couch.

She had turned the lights down low and the reflection of the flames from the fireplace sparkled off her warm, hazel eyes.

“Sorry,” he grinned. “I didn’t mean to be gone so long.”

“Don’t worry about it,” she grinned back at him, stepping around him and heading for the bathroom. “I’ll be back. Make yourself comfortable and have a glass of wine…”

“Okay,” he grunted, watching the sway of her hips under the shirt as she strolled away.

Sitting on the couch, sipping his wine, he watched the flames frolic in the hearth, sending shadows dancing on the walls in the dim light. He was feeling warm and cozy, partially due to the fire’s warmth and partially due to the wine. A curious inSeanacy filled the room, as he sat on the couch while his beautiful sister was down the hallway in the shower.

Naked.

Not that he had experienced the inSeanacy of marriage, but this felt a lot like what he imagined life with the right woman would be.

Suddenly, he felt another stirring down in his pajama bottoms. The thought of her standing under the warm water, letting the spray caress her beautiful milk-laden tits, immediately took its toll and his cock was once again fully erect…and ready.

Ready for what, he angrily asked himself. She was his sister, for Christ’s sake!

Thinking back, he remembered their closeness as children. What a long time ago that had been. Now she was twenty-six. She was married, and had a baby. He was sixteen, horny all the time and always looking for a piece of pussy no matter the source. He had to admit, he still loved her. And he knew the way he felt toward her. But that platonic love for her could easily cross the line and become something much more.

Much, much more.

Then that day ten years ago came rushing into his mind…

She had been twenty and he had been ten. They had been messing around in their Dad’s work shed out behind the house doing something. What, he couldn’t remember. He had just been entering puberty, and was beginning to notice that girls were different than boys. Different in such a nice way. He had noticed that Cynthia’s breasts were starting to stick out against the front of her dress, and he felt a new and curious need to see them.

The memory of that incident played itself out in Technicolor, on the wide-screen of his mind…

“How come your, uh, those are sticking out like that?” he asked her as he pointed at the bodice of her dress.

“Those are my breasts, silly. They’re getting bigger,” she smiled condescendingly.
