I was surfing my iPad on the sofa when Chloe sauntered in. She was only wearing jeans.

“Have you seen my strapless bra?”

“Why d’ya need a strapless one?”

“I wanna wear my off-the-shoulder crop top, and I hate visible bra straps.”

“I think it’s in the wash, babe, sorry. What’s the occasion? Do you really need a bra at all?”

“Well, it’s just coffee with Kate and Ruby, but, I mean, yeah, I think so, Dad, otherwise, won’t they, like, jiggle around and be a bit, kinda, in your face?”

“I don’t think so, sugar, that crop top’s pretty loose on you.”

“Hmmmm, yeah, but do you think my breasts are firm enough?”

Just turned nineteen, she’d never looked so beautiful. A flash of golden earring glistened through her messy mane of thick, dark hair, and her brown eyes were like liquid pools. Full lips promised the sweetest kisses, and her breasts, my God! Each on its own a thing of beauty, but together, as a pair, they were simply spectacular.

I tried to sound thoughtful: “Er, yeah, I think so, love. Come here a minute, please.”

She crossed the floor and stood above me. The iPad on my lap started to tilt as my penis rose up through the thin lounge pants beneath it.  

“Come and sit on daddy’s lap.” She went to kneel astride me, but I stopped her. “No, babe, turn around, please. Yes, that’s it.”

As she lowered herself onto me, I pulled away the iPad, then held her hips to guide her down. Her bottom settled onto my lap, and she let out a little squeal of surprise—or perhaps it was delight.  

“Now, let’s see about these breasts of yours.” My hands went round and gently cupped her tits; my fingers danced along their undersides with a featherlight caress. She gave a little sigh as I marvelled at their warmth, their softness, and their size.  

“I think you might need some new bras, honey.”

“Why?”

“What cup size are your current ones?”

“D.”

“Well, these aren’t getting any smaller, are they? I think you might need double D.”

“Are you sure, Daddy?”

My hands moved up and over them, savouring how full they were, how plump and smooth, until my forefingers reached her nipples, which I noted were erect. She wriggled on my lap.  

“Yes, darling, I’m certain. Now, let’s see about the firmness issue.”

I gently lifted them; they seemed almost weightless, despite their size. 

“Have you heard of Isaac Newton? Did you study him in school?”

"Yes, I think so, Daddy. Did he invent the apple?”

I had a little chuckle and kissed my daughter’s neck.

“You’re so adorable, sweet cheeks, but no, he discovered gravity, although yes, he used an apple. Do you know what gravity is?”

She shook her head, the fragrance of her hair making my cock push even harder up against her jeans.

“It’s what makes things fall to the ground. Despite your breasts being such a lovely size, their firmness makes them defy gravity.” My forefingers did circles of her nipples, which were now standing out like bullets, before I cupped her orbs again, pushing them together. “You don’t need a bra today.” 

“Thank you, Daddy,” she went to get up, but I pulled her back down into my lap, making her yelp with excitement again.

“But, babe, I have a question: If you hate visible bra straps, why have you got the sides of knickers pulled up so high above your jeans so that everyone can see them?”

And they were. Two thin strings of material arcing high on her hips at least three inches above the waistband of her trousers. I slipped my fingers underneath each side, pulled them out, then let them snap back against her body with a twang.

“Oh, Dad, don’t be silly; that’s completely different. This is a fashion hack, a viral meme.”

“Ok, now it's my turn for a lesson. What’s one of those when it’s at home?”

“Oh, come on, you old fossil; it's the hottest trend on social media. These panties are explicitly designed for it.”

“Explicit is right, sugar. Do you really want everyone to know that you’re wearing g-string undies?”

“Don’t be such a fuddy-duddy; it’s just playful little style flirt.”

“What’s the rest of them like?”

“The rest of what?”

“The rest of the knickers. Do they have a normal front and back?”

“Well, I mean, they’re obviously kind of minimal; that’s part of the idea.”

“How minimal?”

“Daddy, don’t be weird. Just like my other thongs and g-strings. Well, maybe a little less material.”

I plucked the ‘strings’ again, making her gasp. “Show me.”

“Dad…”

“Don’t be weird, Chloe, I’m just curious about this viral meme.” My hands slid around and undid the button of her jeans. This time as she rose to stand, I let her, my cock now free to spring up vertically, straining my trousers almost to breaking point.

She started to wriggle out of her jeans. Slowly. Very slowly. Deliberately prolonging the delicious anticipation, uncovering first a tiny triangle of black material nestled at the top of her cleft, and then, little by little, inch by inch, the two plump globes of her buttocks were revealed in all their glory. As she lowered her jeans down to her knees, she bent at the waist, pushing her bum into my face.  

“Stop there a minute, sugar.”

I placed one hand on each of her butt cheeks and pulled them an inch apart. 

“Ah…” a little whimper.

So that’s the string of the g-string.

“Ummmm.”

“Doesn’t it chafe you here, my pet?” I gently touched her anus with my finger.

She giggled, “No, it sort of tickles, but in a nice way, just like that does.” She turned to look at me over her shoulder in a way that made my cock pulsate. 

“Yours is very pretty, Chloe, so tight and tiny, and such a lovely pink.”

“Thank you, Daddy." Her voice was soft and low.

I quickly scooted out of my lounge pants and brought my thighs together. My cock had never felt so hard. Chloe kicked off her jeans. 

“Now, what about the front of them?” I took her hips and slowly lowered her, pushing my erection forward so that it went between her parted thighs, and tight against her panties, as she settled on my lap.

I moved my hands round to the front and traced the seam of the material along its top, then down each of the sides to where they joined to meet the string, between her pussy and her bum hole.

“They are very minimal, aren’t they? Good thing you’re so smooth down here.”

“Thank you for my monthly waxing, Daddy; I love to be completely bare.”

My cock was throbbing. Four or five veined inches, and then my swollen cockhead, all protruding from between my daughter’s thighs.

With a gossamer touch, I traced the line of Chloe’s slit beneath the damp black cotton until I found her clitty.

“Oh! Daddy, that’s my special bit.”

“Baby, you’re very hot and very wet.”

“Sorry, Dad, I know it’s wro…”

“Sssshhhh now, sweetie.” I circled my finger around her bean. It was as big and as hard as her nipples.

“Oh yes, Daddy, please don’t stop." Chloe’s hands went up to cup her tits, brazenly squeezing them together and then pulling apart so she could dribble a string of drool onto my bellend.

“Ooooh, fuck yes, baby, that’s sooo good,” the coolness of her spit felt delicious on my red-hot tip.

I slipped my fingers inside the tiny triangle and made direct contact with her clit.

“Ooooooh, hmmmmmmm, don’t stop, Daddy.” She was wriggling and grinding on me, starting to shake and tremble.  

Then my prayers were answered as she wrapped one of her little hands around my moistened shaft and began to move it up and down. The softest, lightest touch, but one that triggered me immediately.

Electrical tingles in the tips of my toes, quivering spasms through my thighs, and a building, a welling up, in my balls and prostate as my orgasm went past the point of no return just as Chloe’s broke, her head thrown back and high-pitched little cries and whimpers as she shook all over, causing her to clamp her thighs together around my shaft just as the first jet of my semen shot about up and out onto her tits followed by a dozen more, coating her face and breasts in a thick layer of my cum. 

In the sticky afterglow, we kissed, licked each other’s fingers clean, then kissed again more deeply.

“So, a shopping trip tomorrow, yeah? Double D bras and lots more of these viral panties,” Chloe giggled and wriggled off me.  

“I think I'd better go and change; these ones seem to be quite sticky.”

“Chloe, honey, one more thing.”

She stopped at the door and turned.

“Don’t mention this to Kate and Ruby.”
