What Is Las?
Ryun was already waiting for me. Before proceeding with the act, I lowered my head to confirm that her lower parts were properly sealed as they should be. "Hmm..."
"M-Master. It makes me a bit shy when you look there like that." Even as she said that, Ryun was spreading her own buttocks wide with her hands, just as I had done to Eila.
I gently inserted my finger toward the hymen, which sat like a valve inside Ryun's vagina. "Hngh!" Ryun flinched, tightening her grip around my finger. Her vaginal pressure was far stronger than the others, and I pushed my index finger slightly deeper, rotating it in circles against the membrane.
"M-Master, that spot...!" Ryun's anus began to twitch rapidly. The membrane, which lacked even a single opening, was a prime spot for stimulating her pleasure, but it was also the most dangerous part that could cost Ryun her virginity.
"I shouldn't tear this, should I?"
"I-I don't want you to use your fingers...!" Ryun's request was explicit. I pulled my finger out and immediately grabbed my member. Even after ejaculating inside Eila, my cock wasn't dead yet. I couldn't die before cumming inside Ryun. Even if I were to die, I had to stay hard.
"Here I go."
Foreplay wasn't necessary. Ryun had quite commendably filled her anus with Lime's slime. She had learned from what I did to Eila and prepared herself. She was both clever and wicked. To think she had prepared herself so I could go straight to the main event.
I pushed my glans into the anal opening nestled between Ryun's fingers. As soon as I entered, Ryun's anus welcomed me, stretching in all directions as if it had been waiting. Truly, this was a body worth the effort of training. If there was no real difference between the front and the back, I felt I could spend my whole life ejaculating here.
It was impressive how the anal opening, which had been tightly gathered at first, stretched to accommodate my thickness. "Huu, haa..." Even then, she was admirable for trying not to make a sound, using Lime as a cushion. The way she kept her back to me and refused to meet my eyes because she was shy was nothing short of wicked.
'Damn, she's tight.'
The pressure was more intense than gripping with both hands. It wasn't the soft, enveloping sensation of a Harpy's vagina, nor the moderate stimulation of Eila's vagina. Ryun's anus was a one-way attack, squeezing me with everything she had. But that pressure was just right. I almost ejaculated just from the strength of her rectum and sphincter, which made it difficult to even move my cock back and forth on my own. Even trying to reinforce my patience with the power of my tattoos wasn't easy.
'This is driving me crazy.'
Ryun's rear opening wasn't a hole for excretion. It was a hydraulic press designed to crush my penis and extort my semen. In this small frame—small enough to be considered petite—the strength of her rectal squeeze was stronger than anywhere else.
"Haa, Master..." Ryun, who had been burying her face in Lime's chest, turned her head slightly back. A relaxed, languid smile still overflowed on her face. "You're going to cum inside, right?"
"Obviously."
I placed my hands over Ryun's, which were still pulling her buttocks apart. As I pressed my thumbs into the back of her hands and pulled her pelvis, Ryun's buttocks pressed firmly against my pubic bone.
"Aah..."
Ryun's anus finally swallowed my entire length. My lower abdomen rested against her ilium, and the weight of my belly intensified the pressure coming from her rectum. "Heh, Ryun. It won't be a problem even if I thrust wildly now, right?"
"Yes, fuu, I can endure this much..." Ryun took a deep breath and gripped Lime's body tightly. Lime supported Ryun with her whole body, and I took a deep breath, rubbing my pinky finger.
"Buuh... h-hik." As her breathing grew ragged, I had the illusion that my member inside Ryun's rectum was expanding even further. Just as a dog's member swells inside its partner during mating, my cock throbbed and grew in girth inside her.
CRACK!
Ryun gripped Lime firmly without a word. She dug her nails into Lime's chest as if she might tear it apart. In my reddened vision, I got down on all fours in the same position as Ryun. I had become a dog mounted behind her.
"Heh, kuhehe!" I placed my hands on the sides of Ryun's waist. With Lime supporting her from the front, there was no need for mercy. I began to go berserk, thrusting all these sensations into Ryun's rear opening.
THWACK.
It wasn't just a single short sound. I thrust my cock forward so forcefully I feared her intestines might rupture. Even though her rectum had widened enough to take me to the root, the inside of her body continued to stretch to accommodate my member as I pushed deeper.
Thwack, thwack, thwack!
This sound wasn't just the noise of my thrusting. Ryun buried her forehead between Lime's breasts, trembling violently. Her shoulder-length brown hair fell like a collapsing sandcastle. But Ryun's anus didn't give up. It was only her first time being penetrated, yet she gathered all her strength in her rear to squeeze me. The pressure was so intense it felt like it would cause my member to necrose.
"Kuhehe, are you going to be dripping this out the back later?"
"I, I won't drip it...!" Ryun shrieked. I rubbed her buttocks gently before slapping her ilium. With a wet, slapping sound, the area where my glans was embedded shuddered violently.
"H-Huk!"
"Heh, my cock is moving in and out right below here, you know?"
Between the cleft of her buttocks, I pressed my thumbs into Ryun's pelvic bone. The sensation of my penis being crushed from the center made my urge to ejaculate surge, and Ryun writhed, clutching Lime's chest in agony.
"But it's too early to cum from just this much!"
The duration of Berserk was three minutes. I had already wasted over ten seconds, and I intended to use every bit of the full-body buff from Berserk for this penetration.
THWACK!
It was the second strike. Ryun's left knee began to wobble. I grabbed her pelvis tightly from both sides and pulled my body back again. Thwack! Thwack-thwack! I slammed my member in repeatedly, up to the third, then the fifth time. Ryun's left knee, losing the strength to maintain her posture, nearly collapsed, but I pulled her toward me with the hands gripping her pelvis.
"Heh, you can't even run away, can you?"
Unless she escaped, she had no choice but to wait for my thrusting to end. Regardless of whether Ryun's posture collapsed or not, I positioned myself for the best angle and pulled my body back. With my glans barely hooked onto her sphincter, my member was almost entirely out of Ryun's body.
"Ah, wait—"
"There's no such thing!"
THWACK!
I thrust my hips forward while simultaneously pulling her pelvis. My cock, several times the length of my glans, entered back to the root. Ryun's intestinal walls shrank for a moment before widening again.
"H-Huuu—!!"
Ryun's head arched toward the ceiling like a dolphin, and she buried her face back into Lime's chest, letting out a gasping, suffocating moan. Her arms, which had been gripping Lime's chest, fluttered like inflatable tube men at an event.
Thwack, thwack-thwack!
Ryun couldn't endure my full-hearted piston thrusts. If I hadn't been holding her up by her lower abdomen, her posture would have collapsed and she would have sprawled out long ago. Just like the first time Ryun was caught by me, she had no choice but to be teased by me, unable to do anything.
Thwack-thwack-thwack!
Back then, it was my fingers in her front, but now I was stabbing her rear with a cock twice as thick and hard as my fingers.
"H-Hng, h-huk, Master, h-hngh!!"
Eventually, Ryun began to plead with tears, letting out suffocating cries. The confident smile she had at first was now pickled in the pleasure of climax.
"A little softer, ah-huk!"
I silenced Ryun by thrusting my hips. Ryun's rectum was certainly as chewy as could be, but what I wanted was to break Ryun's virginity and thrust deep inside to sow my seeds in her womb.
"Why did you have to be born so narrow, why couldn't you grow a little wider!"
Perhaps because I was excited, all sorts of things were spilling out of my mouth. I held back the curses only because Ryun was looking back at me, panting with her tongue out. Ryun was arching her head back to look at me.
"H-Hng, I'm sorry for being born narrow!"
"Damn it, get pregnant from the back! Lay an egg with your anus!"
"I'm sorry! My body can't lay Master's eggs, haa-ack!"
Even while being insulted, Ryun squeezed my cock tightly with her rectum, saying it felt good. The light on my arms, which had been gripping Ryun's pelvis, began to fade, and I pulled my member out for a moment to prepare for the final spurt.
"Ah...?"
Ryun felt both confusion and relief. But I immediately pushed my cock under Ryun's crotch.
"M-Master?! That's—!"
"Damn it, I don't care!"
Squelch!
I pushed my glans into her vulva. Only the glans barely entered, and the tip was touching her hymen.
"T-That spot?! Wait a minute! Master!"
"I'm cumming!"
Vrrrt!!
My balls trembled more violently than ever before. My cock, which had been on the verge of ejaculation inside her rectum, finally released as the light of my tattoos faded. I had been piston-thrusting into Ryun's rear, but just before ejaculating, I pulled out and pushed my glans into Ryun's vagina.
Thud-thud-thud.
And I ejaculated inside Ryun's vagina. The semen that escaped through my urethra hammered against Ryun's hymen, which had no opening.
"Haaaaaang!!"
Ryun screamed as she reached her climax. Since I had forced my cock head into her already tight and dry vagina and ejaculated, Ryun had reached her peak from the new sensation of being ejaculated onto her hymen.
"Huu, huu."
The light of the tattoos went out, and after one final massive ejaculation, my cock shrank to two-thirds of its size. The hideous protruding veins subsided, and the glans shriveled until there were vertical wrinkles on the surface.
Plop. Thud-thud.
Ryun's vulva twitched once, and semen poured out like a waterfall. Ryun had a confused expression, and I carefully inserted my trembling finger into Ryun's vagina.
Squelch.
The warm, freshly ejaculated semen greeted my finger. I pushed my finger through the semen, sweeping the bottom of the semen lake in a swirling motion.
"Damn, for a hymen, this thing is rock hard."
The hymen blocking Ryun's vagina was still holding its ground. It seemed I needed a smaller battering ram than mine to pierce the gate to her womb.
"M-Master...! What will you do if I can't evolve!"
"Then you'll just become chocolate milk. Haa..."
I waited for the System's judgment. Honestly, I just wanted the System to give me a simple verdict. I checked Ryun's evolution conditions; she was still in a virginal state.
"Heh, heh."
I had ejaculated inside her vagina, even if it was outside the hymen, yet she was still considered a virgin because the hymen hadn't been pierced—it was absurd. But at my state, Ryun blinked with anxious eyes.
"P-Perhaps...?"
"You're a virgin. Crazy."
"Wow..."
Ryun let out a hollow laugh with a vacant expression. Then, with a silly smile, she flopped over to the side. "...Then, can we do about two finger-lengths' worth with Master from now on?"
"Who knows. My ejaculation is so strong I might end up piercing it."
I truly wished I had. To think it was a perfect hymen that could withstand a semen blast without even a scratch—if this wasn't a barrier, what was?
"...Still, I'm glad we tried. Right?"
"Haa, yes... It was good. Truly."
Ryun lay flat on the bed and placed her hands over her crotch. She seemed to have deep thoughts about the ejaculation that had hammered her hymen.
"Master."
"Why."
"Could you do it just one more time?"
"...What will you do if it pierces even a little bit then?"
"Then, at that time, you'll really pierce it for me, right?... Hehehe."
"Heh."
I couldn't help but laugh at Ryun's commendable words. Ryun smiled softly at me, closed her eyes, and fell into a sleep like a faint, with semen still pouring from her vulva like a waterfall.
"...Haa, I'm too tired to do it now."
Having ejaculated into three people in a row, and having used my full strength on Ryun, my body was naturally exhausted. I sprawled out on the bed.
"...I'm sorry, but you'll have to handle it yourself."
Kkeureureuk.
As if to say that was fine, Lime absorbed the foreign substances around her, then created an anus to mount me, mimicking both Eila and Ryun at once. Lime covered me with her entire body, and I felt the heat of my body subside as if I had entered the sea on a summer day.
".......Haa."
I was truly glad I had escaped. I closed my eyes quietly under Lime's blanket of body fluid.
"U-Um, Master? Arthur told me to come, so I'm here...?"
"Ah."
In the end, I was only able to fall asleep after getting up and ejaculating thin semen inside Lily.
