I dragged our luggage up the path as my wife went on without me.

“Come to granny!” she exclaimed, the moment our daughter opened the front door, holding our grandchild in her arms. I couldn’t help but smile, either. Billy was the cutest little bundle of joy I had ever laid eyes upon.

The last time I felt that way was when Sam was a newborn, twenty years ago. Now she was a mother herself. A fully grown woman. That dark pulse buried inside me crawled up, poking the surface of my brain. Fuck, Samantha had an amazing teen body, further accentuated by giving birth. The dress she wore still hugged the curves of her hips and exquisite legs.

What really got to me, though, were her breasts. I couldn’t help but check out the deep valley of her cleavage, made sexual and obscene by how full and engorged they were with milk. I swallowed as we hugged, her feminine scent invading my nostrils and making my dick stir with need.

“Thank you for coming, daddy. I appreciate it.”

I smiled. “I wouldn’t leave my baby girl in the lurch.”

It was a three-hour journey to Sam and her husband’s new home. Paul was a welder. He recently landed a job as an offshore oil rig welder, and the pay was too good to ignore. But it meant Sam was left home alone to look after Billy for a few months. I knew Sam could handle it. She was a tough little thing. But Linda wouldn’t have any of it. Besides, she relished the chance to spend some quality time with her grandson.

“I’ll show you guys to your room.”

The plan was to stay for a couple of months. Linda would help look after Billy and I would... Well, potter about like an idiot, I guess. I ran a small renovation business, but I had a good team with me. I spent years in the trade but as I got older, I was relegated to more administrative duties. It gave me plenty of flexibility. I probably would have to pop back now and then, but most of the time, I could manage things with my phone and email.

The itch to get my hands dirty was there, though. Sam showed me where Paul’s tools were in the garage and I went around the house to see if there were any small jobs I could do. Change a tap here, and see about mending the garden fence. It was kind of fun planning these mini-projects in my head, and it made me feel useful.

It happened on the third night. I was twiddling about under the bathroom sink and needed an extra small spanner. Paul didn’t have one, so I went to check out my own toolbox in my car. In the unlit hallway, I passed by Samantha’s bedroom and the slice of light coming out of her bedroom door stopped me in my tracks.

It was wrong, I knew it. But something at the base of my spine compelled me. I knew Linda was downstairs with Billy. Just fifteen minutes ago, Sam had fed him in the living room, and her mother sent her up here to rest. Linda was more than happy to cradle Billy and watch over him.

A strange, illicit thrum of excitement washed over me, my eyes on my daughter’s body. She was on the bed, asleep in her nightgown that was partly undone. I swallowed. I could just about make out the curve of one of her sizable breasts. I knew she expressed it earlier, but they still looked so full.

Eyes still closed, she yawned. She casually scratched at her chest, catching the fabric. The movement pulled it aside, exposing a breast. I groaned and clamped my hand over my mouth. The air suddenly felt thick with tension.

Her breast was so soft and pillowy, like a water balloon. My lips felt dry as I gazed longingly for her gumdrop-sized nipple. Her areola was tanned a few shades deeper from pregnancy. Even from the door, I could make out the tangerine texture of her areola.

“Oh, daddy,” she moaned under her breath. The word shook me to the core. And then her hand drifted up to her exposed breast, and she gave it a casual squeeze.

“Fuck,” I gasped in near silence. Drops of milk beaded out and ran down the side, making me lick my lips. What a waste.

My cock hardened, demanding relief.

Sam’s other hand disappeared between her legs, and a low purr escaped her lips. Her face went tight, and she brought her hand up to the light, showing off how fucking soaked she was.

“A-ah, no… Stop, daddy…” she moaned. My god, she must’ve been having an erotic dream.

And I was in it.

She splayed her legs and pulled her soaking wet panties aside and started running her delicate fingers along her inflamed pussy lips. I groaned again, fishing my painfully erect cock from its confines, choking it in my desperate grip, milking my need.

“Fuck,” she cried out as her fingers disappeared in and out of her sopping-wet cunt. Her breaths came short and stuttered, and she kept calling for me.

It was such a sexy sight, watching my daughter kneading her breasts, making milk leak out, and teasing her cunt to oblivion. My own orgasm welled up inside me like a kettle boiling over.

“Ohhh, daddy. Give me your cock, she begged, her face taut with pleasure. Her hips curled against her invading fingers and I knew she was getting close. Her other hand tugged at her nipple painfully, forcing more and more milk to spray out.

“Daddy, you’re making me cum,” she moaned.

And then she yelped. My hips bucked and shuddered against her hand riding the waves of her taboo fantasy.

“Sweetheart,” I groaned. I gritted my teeth, fighting the urge to cry out. My cock jolted violently, spraying cum all over the door frame and dripping onto the carpet.

Sam collapsed back onto the bed and seemed to settle back to sleep. I waited for a few minutes, catching my breath and watching her half-exposed, gorgeous body, before I snuck away. My heart thundered in my chest. Knowing what type of taboo fantasies my beautiful daughter harboured made staying here a hundred times harder.

“You not eating? You’ve been pushing that bloody piece of toast around for the last ten minutes.”

“Just tired,” I said.

My wife wiped her hands and leaned in. “You better not be watching those X-rated movies on the television late at night. I know those improper channels are available. This isn’t our house, so I expect you to have some restraint.”

“Damn it, woman. What do you think I am? A monkey in heat? I was doing no such thing.”

“So, why were you going downstairs multiple times last night? It was disturbing me.”

“I- I couldn’t sleep. The not used to this place.”

I couldn’t very well tell her my dick was getting hard thinking about our daughter masturbating over me. My dick twitched under the table over the fond memory.

“Morning, dad. Morning, mom,” Samantha said, with little Billy in tow. “Sleep okay?”

“I’m fine dear. Your father, not so much.”

“You okay, dad? Had a hard one last night?”

“W-what?”

“A hard night? I know it’s hard settling in an unfamiliar place. Took me a while to get used to here, too.”

I felt my cheeks get red. “I’ll be fine. The bed was quite comfortable.”

“I’m glad. I hope I didn’t disturb you. I swear I sleepwalk or something. Paul complains that I’m always talking and doing things with my hands when I’m sleeping, so I hope I didn’t startle you.”

“O-oh, not at all. I didn’t see anything.”

Linda picked up Billy and started bouncing him in her arms. “I think Billy would like to go to the park with grandma, and then maybe he would like to go do some shopping! What do you think, Billy?”

My baby squealed nonsensically and wiped his drool all over his grandmother’s shoulder.

“I think that’s a yes!”

“I’ll get my hat,” I said.

“Oh, bosh to that, Harry. I know you don’t really want to come watch me burn a hole in your wallet. I’ll spare you the torment.”

“Can’t you just not burn it at all?”

“And what will we do with the money? It’s there to be used. Isn’t that right, Billy?” He goo-gahhed in agreement.

“Why don’t you make yourself useful and help Sam around the house? God knows you don’t do enough of that at home.”

I sank back into my chair. Shopping wasn’t something I enjoy. “I’ll make sure to be useful.”

“Would you like me to come?” Sam asked.

“No, I want you to rest. I remember vividly how tiring it was to constantly look after a little one. You rest.”

“Thanks, mom. I appreciate it.”

***

The minute the door closed, Sam looked at me. “Don’t worry, dad, you can just put your feet up and take it easy, too. I’m just glad you and mom are here to keep me company.”

“Your mother is a natural with Billy. But I’d like to do what I can around the house, too.”

She relented and rattled off a list of things her husband didn’t get around to doing. Then she winced.

“You okay?”

“I need to go sort something out.”

“You’re not in pain, are you?”

“Oh, dad. No. It’s just my boobs are aching. They’re full and I need to pump.”

“Oh,” I said, my face flushing red.

She giggled and went upstairs.

A few minutes passed, and I barely got out to the shed before Sam called for me.

“Dad? Can you come here a second?” she called out of the window.

I went upstairs and knocked on the bedroom door and entered. The moment I saw her, my eyes went wide, and I spun around. A machine was attached to her breast, whirring away and drawing the milk out and pumping it into a bottle.

“Sorry, I didn’t mean to walk in on you like this,” I muttered.

She giggled. “This is rather embarrassing, but can you lend me a hand?”

I scratched the back of my head. “I—I never helped your mother out with this sort of thing. I don’t know if I’ll be any good.”

“It’s not complicated,” she said over the whir of the pump. “It’s a lot easier with two people. Please, daddy.”

I licked his lips. “I—I suppose I can’t leave you in the lurch.”

I sat on the edge of the bed. My nerves frayed. Christ, I didn’t know where to look. I swore I could sense amusement in her eyes.

She grabbed my hand and placed it over the cup. “Just hold it tight against me.”

With her hands, she cupped the sides of her lactating breast and applied more pressure. A moan escaped her lips, as milk flowed freely from her nipple. I let out a breath as I watched, mesmerised by the sight of my daughter’s milk being extracted.

“You have no idea how good this feels,” she sighed. “It's just so tight and full and you’re making me feel so good. Thank you, daddy.”

“N-no problem,” I swallowed.

We sat there as the machine worked, filling the bottle. Eventually, the milk flow started to ebb and slow down.

“Is that everything?” I asked.

“We still have the other boob.”

“Oh.”

Sam pulled the cup away and undid the bottle. She placed a cap on it and replaced it with a fresh bottle. She pulled aside her gown, exposing her other breast. She didn’t bother trying to hide away her drained boob.

“Can you see the difference between the two?” she asked as she rigged the machine up to the other breast. “I can’t believe how much milk I make!”

“I suppose there’s quite a lot,” I swallowed.

“Give it a squeeze.”

“What?”

Sam grabbed my hand and placed it over her free breast. “Give it a squeeze, daddy. You won’t believe me otherwise,” she purred, smiling innocently.

My cock pulsed in my trousers. Tentatively, my hand clasped over her milky white flesh. Sam moaned as her rock-hard nipple grazed against my palm.

“If it feels fatty, not squishy like a water bed, you know the breast has been adequately expressed,” she said.

“I-I see.”

I squeezed a bit more, maybe out of reflex and milk shot out all over my hand.

“Sorry, there’s still a trace amount in me,” she chuckled. “Would you like to taste it? It’s good for you.”

There was a pause between us.

“I don’t know. Would that be weird?”

“Well, do you want to taste it?”

I swallowed. “I am curious.”

“Then do it,” she whispered. “I won’t tell mom.”

I looked at my hand. The sweet white liquid was just there. I licked my lips and brought my hand to my quivering mouth. And licked.

“It’s very sweet.”

“It is. A lot of guys drink it nowadays. It’s completely natural. Just a lot of people still find it strange. Taboo, even.”

He simply nodded, possibly because he didn’t know what to say to that.

“Would you like some more?”

“Oh, no. I couldn’t possibly take Billy’s milk away from him.”

She laughed and gave my thigh a playful squeeze. The fact that an erection was visibly pushing against my trousers did not seem to bother her. “I hate to admit it, but I make far too much milk. I throw away most of it. Or sell it. Why let it go to waste, right?”

“That’s very smart of you. I-I guess if you have plenty to spare, I wouldn’t mind a taste.”

She pulled the freshly filled bottle off her teat and I reached for it, but she pushed my hand away.

“Oh no, the bottle is for Billy.”

“What should I do then?”

She looked at her breasts. “There’s still some milk in me. I can feel it. If you don’t mind, daddy, would you like to drink it straight from the source?”

“I’m not sure if that’s appropriate,” I rasped. Despite my words, my heart fluttered with joy. I wanted to attach myself to her teat and never let go.

“Please, daddy,” she begged, tugging on her nipples. “It still aches.”

“O-okay. I’ll help you.”

Sam smiled and shimmied up the bed, and I joined her. I felt my blood pulsing in my ears, as I felt like I was about to cross a line.

“Um, how do we do this?”

She grabbed her breast, the one that she just finished expressing, but still had some milk in it. With a squeeze, fresh milk dripped out. “Simple. You put your mouth over it and suckle.”

I swallowed and simply nodded. I must admit, I felt a little silly, being a grown man crawling up to a woman like a baby waiting for milk, but all that evaporated the moment my mouth latched over her nipple. Hot milk shot into my waiting mouth and I moaned around her teat.

Her hand reached up and cradled the back of my head. “That’s it, daddy, drink it up.”

I moaned again and swallowed down her delicious milk. Now and then, I would lash out my tongue and tease her nipple, making her moan and squirm with pleasure.

“God, this feels so wrong, but so good,” my daughter gasped. “Don’t you think so, daddy?”

I didn’t let go of my nipple. I feared if I so, I wouldn’t get it ever again. Instead, I moaned in agreement. Sam grabbed my hand and placed it over her other breast. I sighed, kneading it greedily, tugging and yanking on her leathery nipple.

“Oh, my,” she mewled. “I can’t fault your enthusiasm, daddy.”

We were like that for a few minutes, her just lying there and enjoying me sucking her breasts. My cock was hard as an iron rod, pressing against her inner thigh.

She chuckled, reaching down and taking it in her hand. “Daddy, what is this? Are you getting turned on by helping me out? Shame on you.”

“I’m so sorry,” I groaned out. Despite that, my hips thrust against her touch in reflex. “Just ignore it. God, just ignore it and please just let me drink your milk.”

Sam unbuttoned my trousers and pushed them down, along with my underwear. My painfully erect cock sprung out, soaked in my own pre-cum. She grabbed my shaft, enjoying how hot it was against her palm and how it pulsed desperately as she wrapped her fingers around it.

“Oh, God,” I grimaced.

“I can’t ignore this. Look how hard it is. When was the last time you emptied your balls? Doesn’t mom take care of you?”

She pumped it up and down. Her hand was so delicate and soft, and the slightest movement threatened to be my undoing.

“I can’t remember the last time we made love,” I stammered.

“You poor thing. I know a thing or two about being sexually neglected. Paul doesn’t have much interest in my post-pregnancy body,” she sighed, making a pouting face.

“Impossible. If you were mine, sweetheart, I’d be enjoying your body every day.”

“I love that enthusiasm of yours,” she laughed. “But can you keep a secret, daddy?”

“Y-yes. Of course.”

She guided my cock until it pressed against her soaked panties. I could feel how wet and eager she was for my cock. She was totally off-limits. But that made me want her even more. My hips lurched forward as if they had a life of their own, trying to force into my daughter’s teenage pussy, separated by a thin sheet of material.

“What do you say to two frustrated adults helping each other out? No one else has to know.”

“I think that’s a great idea,” I agreed.

“Good,” she purred. My daughter yanked her panties aside and my hard cock plunged into her instantly.

“Ohhh, daddy,” she cried out from the sudden feeling of her pussy being filled with my cock. It felt so hot and tight, and the look of absolute bliss on my sweet daughter’s face was priceless.

“Oh God, oh fucking God,” I whimpered.

It was as if I lost all sense of reason. An animal need consumed me and I slammed my cock in and out of her like a rabid beast. I was going a little mad with lust. I couldn’t focus on anything other than the forbidden tightness of my daughter’s neglected pussy.

Sam looked at me, and suddenly, she leaned up and kissed me on the lips. That set off another hunger inside me and I returned the kiss with a desperate fervor, snaking my...
