After stacking Sophia's ass over Katherine, Zed started alternating between their pussies. He made gentle love with Sophia while getting in fucking-mode once inside Katherine.
Sophia felt the balls slap on her ass as he slammed into her mother. The sound of flesh hitting flesh overpowered everything, even the moans of pleasure.
Such high intensity of the strokes surprised her, but she theorized it must be her mother's instructions.
She must be making them learn something new!
This made her cunt gush from fear and anticipation.
What must hardcore fucking feels like?!
Surely she would be able to handle it if her mother can!
Afraid but also excited, she nuzzled her lips on her mother's neck, nibbling on the sweet-tasting skin. Simultaneously, she reached for her mother's ample breasts.
They were soft and pliable and yet also firm! She couldn't help but squeeze them together.
Katherine moaned, and her tits swelled further. Sophia caught the nipples between her fingers and tweaked them, causing her mother to bite her lips.
"Mom! You have such wonderful breasts!"
Sophia praised, but Katherine was in no state to respond.
Zed was once again inside her. She could only cry and whimper.
While barging his cock into her wanton pussy, Zed observed her smooth ass. It was buttery, and he couldn't help but wish to squeeze his face between those cheeks.
He couldn't do that, so he did what he can.
After lubricating his fingers with juices inside Sophia's cunt, he thrust one of them into Katherine's anal opening.
"!!"
Feeling him in her forbidden hole, her eyes once again widened in fear.
Her anal muscles were tight but offered no real resistance to him. Pleased, he thrust another finger and soon started scissioring motion inside her gaping hole, stretching her tight ass.
"Oh god!" Katherine cursed in her heart. "This wicked bastard must be planning to take my ass!"
Afraid he might take advantage of this position and really penetrate her virgin ass with that big cock, she decided to change position.
When he pulled out of her to stroke into her daughter, Katherine's body flashed with lightning speed, and she changed both their positions.
She made her daughter lie below, and she lay above her, their breasts squeezed together. In this way, they formed a beautiful sandwich of mother-daughter.
"Now my ass is safe!"
Alas, Katherine was muddleheaded from orgasms and didn't realize this position would instead make it easier for Zed to invade her ass if he wants to. But she was secured in her belief of him not doing anything against his established personality!
Below, Sophia pulled her muddleheaded mother's face for a wet kiss. While doing so, she fondled her mother's breasts, squeezing them roughly.
Soon, she slipped down and grabbed one of the titties to suck. She suckled on it like she was a child, but there was no child-like innocence for Katherine. She knew how wrong it was given the present situation, and this caused her to shudder from the forbidden excitement.
Behind, Zed was going to penetrate Sophia, but seeing her actions, he decided to help her. He stroked into Katherine, his hips blurring as he fully entered her.
Katherine's mouth flew open, and she screamed in pure bliss.
Her daughter and Zed continued, and soon, their collective actions lead her to a chain of orgasms.
"No more…please…." She pleaded.
Sophia let go of her mom's titties and moved up, bringing her mouth back to her mother's. She kissed her gasping mouth.
"Mom!" She said after the kiss came to an end. "With Zed, you don't have to worry! He would stop!"
She looked at Zed and requested him to come near her face. And like she expected of him, he has already pulled out of Katherine, and on request, arrived before her.
He wasn't caring about the pleasure he was getting from her mother's cunt!
"See! That's why I love him! He always prioritizes others' happiness before his!"
Sophia took hold of the base of his cock and leaned up, taking his balls in her mouth.
Katherine was surprised, but she leaned up. Knowing her daughter was a fast learner, she couldn't afford to be slow.
She took the crown of the cock between her lips and started sucking it like a lollipop. She tasted three different flavors, a mixture of all their essence, and she slid her lips down to suck more.
Zed's head arched back, and he groaned. He was in heaven and relatively close to his dream of ideal death. One woman was sucking his balls while the other his cock.
If only a few dozen more women were joining the fun, he wouldn't mind dying now.
Sophia slipped his balls out and dragged her tongue up his shaft. It met her mother's sliding tongue, and soon, they wrapped around the middle of the shaft.
They moved their tongues up and down his the cock together, coating it with their slippery saliva.
This continued for minutes and stopped when Sophia felt her mother must be ready for another round.
Zed realized her intentions, and he moved back their legs. Rubbing his cock against Sophia's labia, he jammed three fingers into Katherine's ass.
Katherine's eyes squinted, but before she could protest, he moved his cock from Sophia's labia and put where his fingers were!
He was inside her ass!
Oh no!
Not there!
He was taking her tightest and only virgin hole!
It was only his mushroom head, but her eyes erupted with tears. Raw pain hit, and she realized she was right.
She forgot to breathe.
She wasn't ready for this cock in her ass! Perhaps never could!
Zed pushed more of his cock in her, stretching her anal opening further. To distract her from pain, he rubbed her pussy, and the pain subsidized.
She felt a soothing pleasure, but the burning sensation remained.
He pushed deeper and slid into her unexplored channel and only stopped when he was more than halfway inside her.
Oh god!
Katherine cried. Just as tears slid down and she remembered to breathe, he pulled back. She sighed in relief, but then, he thrust upwards.
"Stop, you motherfucking bastard!"
Katherine begged in her heart.
"You are going to kill me!"
The burning sensation has disappeared, and now she felt a flood of pleasure she couldn't handle.
The third stroke hit her, and the dam of pleasure broke.
Her eyes glazed over, and her tongue lolled out.
Zed didn't know it, and he stroked further. The resulting sensation took over her senses, causing her lolling tongue to drool.
Sophia was stunned.
What happened?!
Just a minute ago, she had resumed nuzzling on her mother's throat but felt her stiffing.
And now this?!
Frightened, she expanded her perception to find the cause. And was dumbstruck to find her mother's gaping asshole jammed.
"Oh, no! Zed!!"
Sophia cried.
"You are in the wrong hole!!!"
"Oh no!" Zed exclaimed, his eyes widening in disbelief.
"Oh, yes!" Sophia corrected him. "You are in her ass!"
"No wonder I felt it was tight down there!"
Zed realized why he felt different.
"It's dark here, so I didn't realize I was sliding into the wrong path!"
"Obviously, it isn't your fault!"
Sophia knew he could do no wrong.
"So, what to do?" Zed asked for help.
"Isn't it obvious, you have to pull out----" Sophia trailed off.
When it came to sex, she didn't know what was obvious! So how could she guide him!?
That job was her mother's! And she was in no state to speak!
"Mother must be wanting this!" Sophia looked at her mother's expression. "Her expression is crazy, but she seems happy!"
Then that must mean hammering the ass must be the right step!
"Stroke into her like you did in her vagina!"
Sophia guided the love of her life to fuck her mother's ass.
Zed nodded and followed her instructions. He started pounding Katherine's asshole…
Sophia helped him by licking her mother's lonely pussy.
They both drove the already crazy Katherine into insanity of pleasure.
…
At the same time, just some hundred meters away from the pool, the fabric of space melted and opened a channel to the lab.
The teleportation portal might be closed by Claudia, but for an Alpha, there were many ways to leave.
One of them involved tearing open the fabric of space.
Something Rebecca now used to leave the lab with her daughter.
It wasn't like Kirstie made a full recovery, but she wanted to come out and experience fresh breath.
"Mom, let me try to walk!"
Kirstie tried to step out of the channel without any help. Rebecca followed behind, ready to help her daughter in case a need arises.
It took her minutes, but she succeeded in stepping out. When she arrived outside, she realized it was midnight.
The cold winds hit her, and she inhaled deeply.
Today was the first night of her freedom from her cursed fate!
"Kiba said I must never waste a second in feeling bad for myself!" Kirstie recalled her brief meeting with Kiba. "And he was right!"
She spread her arms to bathe in the starlight and enjoy the environment.
OW! OW!
~SLAM~ SLAM~
Her reverie was broken by the sound of flesh hitting flesh.
"What's going on there?" Kirstie looked in the direction of the garden.
Rebecca arrived next to her and looked in the direction.
Unlike her daughter, the presence of trees and darkness didn't hinder her vision.
Instantly, her vision zoomed in, and she saw the scene next to the pool:
Zed plowing Katherine's ass while Sophia capturing the latter's clit between her lips.
"!!!"
Rebecca staggered back, her mouth agape.
