******** Preparations ********
At night, both twins are embarrassed and shy, partly because of Shi and Song's presence. But they're no longer scared, and even look forward to it. The sisters' cultivation is somewhat below the other two, though not by much.
With the four of them, I can push the container to its maximum. So, I can use Rui's extra qi to practice. Of course, I could also absorb less and have them practice more, but they've refused. They've decided that the priority is for me to get stronger. I've had to accept their decision. In fact, they're right. I'm the one who's most exposed.
The twins may be embarrassed, but that doesn't protect them from Shi and Song. They've been forced to get on all fours, and the other two have done the same. I gulp at the scene. I know they're doing this to get them over their trauma, so I penetrate Song first. That way, they can see her enjoy herself. All four of them are wet, they've been masturbating while they all gave me a blowjob. Shi's orders. At some point, she's become the boss.
"Haaaah! Yessssssss!" Song moans when I reach the deepest in the first thrust.
I grab her buttocks, reveling in their elasticity as I enter and exit her. At first, gently, but I speed up. Not only that, but my thrusts are increasingly longer. I almost completely exit her and then push all the way in.
"AAAAAAAH!! Kong!! You!! Mean!! AAAAAAAAhhHHH!!!"
"It's amazing how her tits move," Yi comments, while staying on all fours and continuing to rub herself with one of her hands. It's soaked.
"Yes... Ahh," Yu moans softly.
"Finish quickly, we're waiting for you... Aaaaah~" Shi begs, wiggling her ass.
Shi moans lasciviously when I slap her ass. I grab Song's buttocks again, and speed up once more. I make her cum several times in a row before we both cum together. When I let her go, she collapses onto the bed.
"Aaah, Kong, mean..." she moans almost without strength, satisfied and catching her breath.
Without waiting and almost by surprise, I penetrate Shi. I immediately ram her again and again, while she doesn't stop moaning.
"Yessh!!! That's it!!! HHAAAAAAHHHH!!! Don't stop!!!"
She's even more talkative than usual. I know it's because of the twins, who're looking at her almost hypnotized.
"She has much smaller ones, but she's so sexy... Aaaaah..." Yi comments
"Yes... Ahh" Yu agrees again timidly.
"She looks like a cat in heat," Song mocks her from the bed.
Like Song, I also make her cum over and over again until we finish together. She also collapses.
"Ah... So intense... We have to do it again another day... Aaaaah~"
I then get behind Yi and caress her ass.
"Don't worry, do it," she asks me.
I listen to her and penetrate her slowly, all the way. Then, I continue moving gently.
"Aaah. Aaaahh! Aah! Haaa! I know... You're so sweet but... I... Do it like them..."
I do what she asks. I speed up little by little, making sure it's okay.
"AaaaaaAAAAHHH!!! So... intense!! HHHHAAAAaaAAAHH!! AAAAAAAAH!!!"
Her arms have lost strength. Now, she's leaning on her elbows, her head against the bed. At first, I made her orgasms soft, but now I let the qi be stronger. She moans. Her breathing quickens.
There was only one moment when she seemed to hesitate. Her vagina tightened. But when she realized that I was slowing, she relaxed, accepting that I didn't want to hurt her. She then raised her ass a little more, asking me to give it to her harder. Now, she's totally surrendered to me, letting herself be penetrated again and again, enjoying it.
"Yes! AAAAAAAAAAAAAAAAAAAAAAAAH!! Incredible!!! AAAAAaaaaaaHHHH!!!!! HHHAAAAAAAaaaaaaahhHHHH!!!!"
When we both finish and she collapses, she turns her face towards her sister and smiles, somewhere between lascivious, satisfied and tender. She takes her hand. Yu raises her ass a little more and directly leans on her elbows, offering herself.
"Do it hard, like you did them," she whispers timidly, unconsciously moving her ass.
Even though she asks me to, I penetrate her carefully, but I quickly speed up when I see that she responds. Her vagina contracts several times, and each time I slow until she lets herself go again. She also stifles her moans.
"MMMmmmmMMM! AAAAmmmmmmMh!! MMMmmMMAAaaAAAMMMMMhh!!"
Finally, she lets herself go completely. Her ass shakes every time I thrust. Her hair falls over her face. Her breathing is perfectly audible between moans.
"How...!? AaaaaaaAAAAHHHH!!! How can it be so...!? HHAAAAAAAAAAAAaaaaaaAAAAAHHHHH!!!!...so good!? AAAAAAAAAAAAAAAAAAAAAAAAAahhh!!!!"
After several orgasms, we cum together. She collapses. I lie down between the two of them, caressing their faces. They settle on my chest, after kissing me on the cheeks. Shi and Song hug them from behind. With affection. We stay like that for some time, until they fall asleep.
I practice a little "Inner Armor", spending qi. I call Rui. After a blowjob, I also put her on all fours. I penetrate her in the ass. She's tight. She isn't ashamed of moaning continuously. It's her reward for behaving well. She enjoys it.
"Tell me, do you want me to make others penetrate you?"
"If master wants I will... AaaaaaaahhhhhHH!!!... but I prefer... AaaaaaaAAAAHH... only master. HHHHHHHAAAAAAAAHHHHH!!!!"
"Good girl."
It was a little "test of loyalty", as the notebook indicated. As a reward, I penetrate her vagina with my fingers and play with her clitoris. She shudders, collapsing on the bed. I don't stop fucking her, though, until she loses consciousness. I guess I'll have to "punish" her tomorrow.
----------
It's been three weeks since the twins joined us. Unfortunately, they have been influenced by the other two. Now, all four of them spend most of their time naked. If I look at them, I need a lot of willpower to avoid an erection.
They spend most of their time inside the Residence, although they do go out sometimes. They're supposed to be secluded in their cabin meditating, so we stop by from time to time to pick up the food they leave for them. They've also used some of the few contribution points they had to buy basic weapons for training, and some slightly better daggers for themselves.
