Time to Enjoy the Back Pussy
"Huu, Roen." Echidna's breath swept across the back of Roen's neck. It was an alluring breath, thick with lust, and Roen naturally leaned her upper body over the table, pushing her hips back.
She was filled with a grim resolve, as if telling her to do whatever she wanted. After all, they had made a bet a week ago, and part of her had simply resigned herself to whatever happened.
Echidna wouldn't feed me anything bad, and even if I lose the bet, I can just live with a slightly unusual body. Whatever.
Come to think of it, not having periods was already a highly unusual constitution for a pure-blooded human woman. Adding one more strange trait to that didn't seem like it would make much of a difference. Anyway, so...
"Hurry up... and do it...?"
She urged her to use her anus in a slightly blunt tone. She was trying to subtly convey the feeling that she had no desire to do this and was only doing it under duress. Frankly, she already had a bad feeling about this.
Roen was no fool; by now, she knew her body was incredibly sensitive, so there was no way she didn't realize she was at a disadvantage.
Ah, damn it... What if I end up coming from behind too...?
She already felt like she had lost before they even started, but she absolutely did not want to give off the impression that she actually wanted anal sex. A woman who enjoyed sex from behind felt somewhat incredibly depraved. At the very least, she wanted to make it look like she was merely being dragged along by Echidna.
"Wait, Roen. Don't rush me."
"W-who's rushing...?"
"Sure, sure." Echidna saw right through Roen's inner thoughts and deliberately began to take her time.
She looks like she's burning with impatience. Her anus has been twitching and puckering because of the aphrodisiac for a while now. If I drag this out a bit longer...
She figured she might get to see quite an entertaining sight.
"Mmh, chupa, slurp." With that in mind, Echidna stuffed her entire right hand into her mouth and began to suck on it noisily. She could have used lube, but that would take no time at all.
Should I secrete a little aphrodisiac too?
Seizing the opportunity, Echidna mixed some aphrodisiac into her saliva, coating her entire hand with it. Unlike Roen, Echidna possessed an absolute immunity to her own venom, allowing her to remain perfectly calm even when exposed to the aphrodisiac.
"When are you..." After about ten minutes of lying face down on the table like she was being punished, Roen let her voice trail off. It wounded her pride, but she couldn't just stay like this forever; she had to ask when on earth they were going to start. However...
"Oh, right, I'll start soon." Echidna deliberately feigned ignorance, continuing to wet her hand with saliva. Then...
Ah, right. She pressed her venomous fang against the thumb of her other hand—the one not covered in saliva—and let the aphrodisiac flow.
"Hng..." As Echidna naturally smeared the aphrodisiac from her thumb onto the folds of Roen's anus to continue the foreplay, Roen lowered her head and cringed at the mere touch of the drug-coated thumb against her flesh.
The human body was simpler than one might think. Since Roen was in a constant state of heat, applying the same type of aphrodisiac to her anus resonated with her G-spot, causing juices to start dripping from her pussy. This happened less than five minutes after Echidna began massaging the anal folds with the aphrodisiac.
Tsk, this is way too one-sided... Echidna felt a bit disappointed for no reason. Roen, who used to barely budge when Echidna trained her manually, was now panting heavily just because her anal folds were being caressed with an aphrodisiac-coated hand. Granted, that was exactly what the aphrodisiac was for, but it couldn't help but scratch her pride as an Alpha.
"Hmm..."
"Hngh...♡" Look at this. Just touching her anal folds—which weren't even a proper erogenous zone—already had her letting out such unchaste groans. She had lost to the aphrodisiac, not to Echidna. That was what hurt Echidna's pride. Well, if anyone asked who had applied the aphrodisiac in the first place, Echidna wouldn't have an excuse... but there was no one here to nag her about that.
"Hngh, mgh..." Unable to endure Echidna's endless caresses any longer, Roen covered her mouth with her hand. She had reached her limit. A single tear welled up at the corner of her tightly shut eyes. She was utterly confused about whether it was okay to feel this much pleasure through her rear—and through mere anal folds, of all things—and she was starting to fear the uncontrollable ecstasy.
To make matters worse, she couldn't even come on her own. While the pleasure felt as the aphrodisiac seeped into her anal folds was outstanding, it was never enough to push her over the edge. The absolute volume of pleasure was immense, yet it did nothing to satisfy Roen's desperate craving for climax. Just like that, the defensive walls in Roen's mind were rapidly crumbling.
It's about time... Watching Roen, Echidna felt the moment had come. It was almost time. Since they were using Roen's rarely touched anus, she was holding out reasonably well, but with the aphrodisiac in play, there was no way she could last more than thirty minutes. And, finally.
"E-Ekidna..." Roen spoke in a trembling voice. After doing nothing but letting out fearful whimpers and gasps with her mouth covered, she finally squeezed out actual words.
"Hurry, just..." However, she couldn't bring herself to finish the sentence. No matter how thoroughly conditioned Roen was, she still couldn't bring herself to ask for fingers inside her anus. She had no pride left to break, but this was her absolute last line of defense. Begging for fingers in her anus? That was practically throwing away her human dignity. That was why she let her words trail off, but...
"Hmm? What? Hurry what?"
"No, I mean..." Echidna teased Roen with an innocent act. Then, she lightly slapped Roen's buttocks with her spit-slicked hand, making loud thwack sounds. It was as if the gesture was urging Roen to say it with her own mouth.
"..." Roen kept her mouth tightly shut for a while, but after Echidna spent another five minutes teasing her anal folds, she helplessly opened her mouth.
"Hurry, put your fingers inside a little too..." This time, the sentence was quite long. However, Echidna wanted Roen to grovel and submit to her even more. She wanted to see Roen submit to her as an Alpha, not just to the aphrodisiac. And so...
"Is that how someone asking for a favor behaves, Roen? Speak clearly."
"Please... put your fingers in..."
"Where? Your pussy?"
"No, um... the back..."
"Where in the back?" Echidna began to abuse her power—a privilege unique to a sentient being with an ego, unlike a mere aphrodisiac. It was almost pathetic how she was now jealous of a drug, but Roen was in no position to care about such things.
"My an... No, my back pussy... Please put Ekidna-nim's fingers in my back pussy. Right now, it's too... agonizing..." After a moment of hesitation, Roen finally submitted and said exactly what Echidna wanted to hear. Echidna's lips curled into a bright smile, but she wasn't satisfied yet. There was still one more step.
"Tsk, we're almost there..." Echidna subtly demanded the next step, looking forward to seeing what creative way Roen would satisfy her desire for conquest. At that...
"..." Roen was lost for words again. What was she supposed to do now? More than this? More politely? More dirtily? What on earth did she want her to do? Her mind was spinning, but...
"Roen?"
"Ahhn..." When Echidna firmly pressed down on her anal folds, all rational thought evaporated. And so...
"Ekidna-nim..." Pressing her forehead against the table, she stood on her tiptoes to raise her hips as high as possible. Then, she reached her hands behind her back and pulled her buttocks apart. All of this was to make it even a little bit easier for Echidna to insert her fingers.
"P-please give my desperate back pussy a chance to climax. My body belongs solely to Ekidna-nim, after all. So..."
"You're the best, Roen." It was a perfect answer. Echidna's lips twisted into a wicked smirk once more as she slid her fingers into Roen's defenseless back pussy.
"Oohh..." With her hands behind her back, she was holding her anus open to make entry easier. As Echidna's fingers firmly scraped and stimulated the inside of her aphrodisiac-soaked back pussy, Roen had absolutely no way to hold back her groans.
"Ah, hah... Hih, heg, haahn...♡" Roen spilled all kinds of lewd cries from her lips as the focus in her eyes began to dissolve. Fearing that Echidna would pull her fingers out if she let go of her buttocks, she gritted her teeth and held on, even as her body writhed and her face repeatedly bumped against the table.
"Haa, Roen. You've really become a total bitch. What should I do with you? Are you sure you're not a dog beastkin without ears and a tail instead of a human?"
"I'm n-not...♡" As if rewarding her, Echidna slid another finger into Roen's back pussy, which she had pre-stretched the night before. Roen's back pussy greedily sucked and clamped down on the fingers.
