Midnight Anal Training
Three days had passed since that late-night anal training session. It was exactly the third day since Echidna had begun conditioning Roen's anus. Tonight, she fully intended to work hard on developing Roen's tight little pucker once again.
"Mmm... Goodnight..."
"Yes, sweet dreams, Roen."
Roen drifted off to sleep with a blissful expression, clearly thrilled with how life had been going lately. And for good reason—Echidna, who usually seemed to think of nothing but sex, hadn't touched her once over the past few days. Even though Roen had a vague feeling this peace was only temporary, having more time to relax was a massive blessing.
However...
"Phew, alright. Shall we begin tonight's session?"
That peace only existed because Roen assumed Echidna wasn't touching her day or night. But when night fell, Echidna naturally laid hands on Roen's body as if it were her birthright. Just because Roen was blissfully unaware didn't mean it wasn't happening.
"First, let's get you into a kitty pose, and then we'll slide in some lube..."
Unfortunate as it was for Roen, her body was being thoroughly conditioned at this very moment while she slept like a baby.
"Now, what if I slide a finger in?"
"..."
However, anal training was no easy feat. After all, the anus was an organ specialized purely for excretion; it possessed no natural function for receiving.
"Hmm..."
Simply applying a bit of lube wasn't going to make her tight ring greedily suck down Echidna's finger, nor did Roen feel even a shred of pleasure from it.
"..."
Instead, she merely knit her brows slightly in discomfort...
"Hmm..."
"Mnh..."
In stark contrast to her dry backside, when Echidna slipped a finger into Roen's front pussy—which was almost always naturally slick and wet—Roen immediately let out a sweet, coquettish moan in her sleep. Her inner walls eagerly clamped down, milking the tip of Echidna's finger with practiced ease.
"Sigh..."
Frustrated by the lack of progress with the anal training, Echidna peeled back her penis-covering scales to expose her massive, imposing jaji. Pulling her finger out of Roen's front pussy, she pressed her thick glans against the dripping entrance.
"Haa... Ah..."
Perhaps startled by the sudden intrusion of a glans the size of a fist, Roen's breathing turned shallow and ragged. Yet, her pussy clamped down even tighter than it had on the finger, lovingly hugging the massive head.
As Roen's internal walls pulsed in sync with her breathing, they squeezed Echidna's glans with delicious, rhythmic contractions...
"Ahhh..."
Echidna closed her eyes, quietly savoring the exquisite sensation before her body shuddered, and she began to succumb to the overwhelming pleasure of ejaculation.
"Mmm..."
Roen's vaginal canal was once again completely flooded by Echidna's overflowing jeong-aek. The warm fluid seeped deep into her womb—where a new life was already quietly growing—asserting its dominant presence.
However...
"Haaah..."
After her sigh of pure satisfaction faded, Echidna let out a frustrated groan, staring down at Roen's pink anus, which was still glistening with unused lube.
"Is there really no other way? At this rate, it's going to be impossible to make her feel proper pleasure from this within a week..."
If Roen didn't willingly open up her backside, Echidna would have to keep using Cleanse every single night to cover her tracks. It was incredibly tedious, not to mention a bit unsatisfying... Above all, Echidna desperately needed a proper place to bury her dick.
"Blowjobs and regular sex are off-limits..."
Handjobs? Titty fucks? Sure, they were nice, but she was starting to get bored of them. Having already experienced Roen actively serving her with enthusiastic eating out, Echidna, as the dominant alpha, couldn't understand why she had to settle for manual labor to satisfy herself. She just wanted to use sleeping Roen's back pussy to comfortably relieve her lust. Since she was keeping her promise and preserving Roen's hymen, she felt she had every right to claim her backside as compensation. Such was Echidna's incredibly selfish logic.
"Haaah..."
Looking at Roen, who was fast asleep in a kitty pose with white semen dripping onto the bedsheets and her anus slicked with lube, Echidna let out another heavy sigh. Such a delicious body lay completely defenseless right before her eyes, yet she couldn't use her front pussy because of that damn hymen. She couldn't even use Roen's mouth since she could only pull her dick out during somnophilia, and now her anal training was on a strict time limit. What a cruel, tragic reality.
"There has to be a way..."
Echidna bit her tongue with a sullen expression. It was a habit she fell into whenever she was anxious, proving that conditioning Roen's anus was a matter of grave importance to her. And as she stood there in silence, lost in thought...
"Ah...?"
She let out a soft gasp of realization. The tip of her tongue had brushed against her venomous fangs—the ultimate pride of a Lamia.
"An aphrodisiac...?"
Among her various venoms, there was one that acted as a potent aphrodisiac, driving anyone who received it into a frenzy of lust. If she injected this aphrodisiac directly into Roen's anus, she could drastically accelerate the conditioning process.
"It's definitely possible, but..."
Honestly, using an aphrodisiac on Roen weighed slightly on her conscience. Although she kept a supply of the drug stored within her body for emergencies, resorting to such measures felt like crossing a line that she had desperately tried to maintain. For the sake of her pride as an alpha, she had wanted to avoid using venom if possible...
"Ah..."
...But.
"I can't help it."
Seeing a drop of semen cling to Roen's plump, engorged clitoris before dripping onto the bedsheet, Echidna's mind was instantly consumed by the overwhelming urge to ravage her.
"This is all to protect Roen's virginity, so I'm not really the bad guy here. Yes, exactly."
Offering up a pathetic piece of self-justification, Echidna immediately buried her tongue deep inside Roen's anus and began secreting her venomous aphrodisiac. From this moment on, Roen's anus was destined to become a literal back pussy.
"Mmmgh...!"
When Roen woke up, she felt incredibly refreshed. It was amazing. Since they barely had any sex lately and she had been going to bed early around ten every night, she hadn't felt this energized in ages.
"I wonder why Echidna has been sleeping in so late lately."
In contrast, Echidna always woke up about two hours later than her. Roen couldn't help but wonder what she was doing while she slept. Come to think of it, Echidna's fatigue seemed to have worsened right around the time she finished developing Roen's medicine. Had she exhausted herself working so hard to make it?
"Oh, you poor thing..."
Roen gazed at the sleeping Lamia with pity and gently stroked her hair. How could someone be so incredibly sweet? Even when Roen didn't ask, Echidna was always whipping up something wonderful for her. The menstruation-stopping medicine was the perfect example. Considering Echidna had been the one to suggest it first, she must be thinking about Roen every single second of the day.
Smooch.
Filled with gratitude, Roen pressed a soft kiss to Echidna's sleeping lips before heading back to her own bedroom. They might share a bed at night, but all her clothes were kept in her own chamber. Last time, she had been too exhausted from their non-stop sex marathon in the Great City to even think about getting dressed, but she was a civilized human being. It was only right to wear proper clothes.
"Hmm..."
However, once she stripped down to change her underwear...
"Mmm..."
She found herself staring at her reflection in the full-length mirror, suddenly feeling self-conscious.
"What does anal actually feel like...?"
She turned around, trying to catch a glimpse of her backside in the mirror, but the angle made it impossible to see her anus. And standing forward, she could barely see her front pussy, let alone her back. Could such a tightly hidden hole really become an erogenous zone? It seemed utterly bizarre to her. After all, she had plenty of perfectly functional sweet spots—her pussy, breasts, clitoris, and nipples. Why on earth was Echidna so obsessed with using her anus that she went out of her way to brew a special medicine for it?
"Mmmmm..."
She let out a low groan, pretending to be deep in thought, but deep down, there was only one reason she was standing in front of this mirror.
"I really don't get it."
"I don't get it, I really don't," she muttered like a mantra as she dragged the full-length mirror over to the side of her bed. Then, utilizing the flexibility she had built up from years of yoga, she sat on the mattress and spread her legs wide into an M-shape...
"See? Even in a pose like this, you can barely see it. Why is she so obsessed with using this place? Common sense says the anus could never feel better than a real pussy. And yet she keeps calling it a 'back pussy' this, 'back pussy' that, making it sound so fancy..."
Babbling excuses to herself, she leaned back slightly. If sitting didn't work, lying down surely would. She slid a pillow under her hips and turned her head to the side, adjusting her angle until she had a clear view of her anus in the reflection.
"Oh..."
Staring at the soft, pink pucker reflected in the glass, she couldn't help but let out a gasp of genuine admiration.
"It's completely hairless..."
She had suspected as much since her front pussy was hairless, but indeed, she didn't have a single strand of hair below her neck. Front or back, she was completely smooth. And...
"Wait, what is this...?"
Meeting her own gaze for the first time, her anus seemed to twitch and pucker shyly, almost as if it were teasingly asking her: Are you really not going to try me out?
