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 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 from 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 babygirl 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 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 shown 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 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 doorframe 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 a unfamiliar place. Took me a while to get used to here, too."
I felt my cheeks got 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."
