Sakura sighed softly, massaging her eyelids with one hand and her clothed cock with the other. She stared down at her sleeping granddaughter with a frown. The girl's long pink hair, two shades darker than Sakura's own, lay pillowed out beneath her, making her look all the more innocent and easily defiled.

Biting her lip, Sakura spun on her heel and left the room, nearly sprinting.

That had been happening more and more lately: Sakura waking from a wet dream to find herself standing above her granddaughter, rock hard and staining her pajama bottoms with precum. And each time, she forced herself to turn away from pretty little Sarimi and head over to Sarada's room to take care of her problem.

After Sarimi had been born (at home, with the help of Hinata), Sakura had bitten the bullet and forced herself to put Sarada on birth control. Which...was helpful?

On the one hand, she couldn't get Sarada pregnant again. On the other hand, that meant that there was nothing stopping her from dumping load after load after thick, gooey load of cum directly into the girl's womb and leaving her filled like that all day.

But Sakura was admittedly a bad mother. And sometimes bad mothers were so focused on their own needs that they forgot about that of their children's.

So it should be a surprise to absolutely no one that the comatose Sarada was so heavily swollen with her fifth child that Sakura had to bury her cock in the young woman's ass to work her cock to completion. Years of pregnancies had left Sarada's chest, ever swollen with milk, at a nice C-cup, enough of a handful for Sakura to grip tightly as she hammered into the sore hole, eventually grunting softly as she pulled her cock out and showered her seed all over her daughter.

Sakura sat back on her heels with a sigh and stared down at the mess she'd made. Rolling her eyes, she got up and left Sarada like that, caked in her semen as she went back to her room.

All she could think about was how badly she wanted to be fucking Sarimi instead.

Sakura could be a good mother sometimes, though, at the moment, she deeply regretted having bothered.

She sat down slowly on the couch, all of energy devoted to not flopping down and waking Sarimi. You see, for Halloween, the little girl had had the great idea of them wearing a tandem costume. It was a two-headed Noh monster, with one head above the other. Sakura had spent a week making the damn thing and then an hour strapping Sarimi's body to her own so that Sakura's head rested on top of hers.

And then she had spent four hours forcing down a hard on at the girl's school with Sarimi wiggling over her crotch because of the harnesses.

And now, with Sarimi having fallen asleep on the way home, she was just too tired to bother undoing the whole thing.

Sakura was minding her own business, having forgotten about her granddaughter's presence, as she got engrossed in the movie on TV. And the sex scene came on. And Sakura, like any hot-blooded dick owner, found herself getting thick and hard.

She found herself jerking her hips slightly, rubbing against the pressure on it as she watched her show. It took her... a truly unreasonable amount of time to realize that the pressure she was rubbing against was her sleeping granddaughter.

And when she looked down, in her mind seeing the way their draping costume would be tented by her fat cock buried inside Sarimi, so much smaller than Sarada had been her first time...well…

She simply couldn't be blamed for what she did next, right?

Carefully, carefully, Sakura reached under the costume and unzipped her pants, pulling her cock free from the slot. Under their costume, Sarimi's legs had been bound to Sakura's legs, and the girl's arms bound to Sakura's sides. So Sakura spreading her own legs spread Sarimi's as well.

Sakura tore a large hole in Sarimi's shorts and used her own precum to finger the sleeping girl. She did her best to try and get Sarimi open as much as possible but it really wasn't long before she stopped caring, so used to being able to just shove her cock into a tight, wet fucksleeve and then just use it.

And with Sarimi all nice and limp and pliable in her lap...Sakura may have forgotten that it wasn't Sarada's cunt she was about to wreck.

The sharp cry Sarimi let out when Sakura forced her way into that too tight space was definitely a wake up call, though.

"Grandma? Grandma! What are you doing?! It hurts! Take it out!"

"Shush, shush, sweetie," Sakura said soothingly despite the fact that she was ramming into the young girl the way one would a well used whore, "It's okay, Grandma just needs to...ah...she needs to stretch you out a bit. It's good for you!"

Sarimi, of course, just cried and struggled futilely, truly stuck on the older woman's cock. Wanting a little more depth, Sakura stood up, letting gravity pull Sarimi down further on her dick, and walked around to stand on one side of the couch.

Sakura bent over the arm of it and then began jerking her hips again, Sarimi trapped between herself and the couch. Each hard thrust forced her cock deeper and deeper into that tight passage until she was breaking through the girl's tight cervix and falling six deeper. Sarimi let out a loud, long sob that was nearly drowned out by Sakura's moan. She hadn't thought that it was possible for anyone to feel better than Sarada had felt around her dick that very first time.

But boy was she wrong.

Unfortunately for the young former virgin, the pain of being breached so deeply had her clamping down like a vice around Sakura's cock, forcing the first of many orgasms from those heavy balls and straight into her womb.

Sarimi gasped sharply, eyes wide, as she felt herself being filled. Pint after pint of that thick heavy liquid filling up her most precious place, causing her stomach to swell with it. Despite her young age, Sarimi wasn't naive. She had a good working knowledge of biology and knew that right now, her grandmother was dumping nearly a gallon of egg-seeking sperm into her womb.

"Grandma, stop. I'm gonna get pregnant! I need to… I need to wash it out!"

Sakura lay down on top of Sarimi, putting pressure on that bloated stomach. "I'm still...I've still got a couple more loads left in me. Just let me finish, okay? I gotta…" Sakura couldn't even manage to finish her own sentence before she was rutting into the girl again.

Sarimi whined softly and went slack, surrendering to the fact that wasn't going to be set free until her grandmother had had a chance to empty her balls.

What she didn't expect was that it would take four hours for her grandmother's massive cock to soften.

What she didn't expect was that Sakura would finish their session with just enough energy to unplug the poor girl but not enough energy to actually unbind her.

What she didn't expect was that she would have to fall asleep tied to her grandma, waiting for morning to come.

What she didn't realize was that mornings meant morning woods .

She couldn't have expected to end up spending four days tied to Sakura, the futa even calling off work, filled with the need to fuck her granddaughter just one more time .

She couldn't have expected that the morning-after pill, taken 5 mornings after the fact, wouldn't work.

She couldn't have expected that to not matter anyways because none of the condoms she'd stolen could contain her grandma's load.

She couldn't have expected, months later, her grandmother muttering, "Yes, take it! Gonna make you a baby factory just like your mom," into her hair as she came inside Sarimi for the third time that day.

Sarimi couldn't have expected any of that because she'd been so sure that her grandmother was good.
