The Forbidden Pleasure of the Back Door
"Alright, I'll take your word for it." I teased her, scooping up a generous amount of Vaseline with my middle finger and spreading it around her pink anus. Unlike gel, it didn't drip, making it easy to apply from the outside. The area around Youngsun-noona’s anus became slick and glossy, like lips coated in lip balm. To think that a hole an ordinary woman would never use was being teased and prepared for penetration—my breathing turned ragged.
"Hut, haaaa-" As I pushed my Vaseline-coated middle finger deep into her ass, her anal walls twitched with a wet, squelching sound. I deliberately made the sound louder, thrusting my finger in and out. Squish, squish, shlurp-
"Do you know how incredibly lewd your ass sounds, Noona?"
"I don't know, I don't know-♥" Sweet moans spilled from Youngsun-noona’s lips. It was incredibly sexy. As I carefully spread the lubricant inside, I thought about the warnings regarding Vaseline. Was it that it could melt condoms? 'Well, I'm not using a condom anyway. Doesn't matter.'
I scooped up the remaining Vaseline and applied it to the tip of my throbbing glans and the thickest part of my shaft. There wasn't much left, so the jar was already empty. It was a bit sparse, but since I’d coated the inside of her anus well, it wouldn't be painful.
"Noona, we're out of Vaseline. If you aren't prepared next time, I'm really going to use yogurt."
"Yes, yes. I'll make sure to be well-prepared next time-" Even as she nodded, Youngsun thought that being treated like that next time wouldn't be so bad. Filling her ass with yogurt while enduring Kangmin's verbal abuse... Squeeze. Her insides tightened around me.
'Come to think of it, Noona is really bad at lying.' She claimed Vaseline wasn't for anal use, yet her anus smelled like body wash—she’d clearly prepared everything while pretending otherwise. I smirked and aligned the tip of my cock with her pink anus. The position was much more comfortable than when I was rimming her earlier.
"My neck doesn't hurt anymore. It feels like this hole was made specifically for my cock. Oh, wait, isn't this place not originally for that?" I asked teasingly as I slowly pushed inside. But Youngsun had no time to answer. She was entirely focused on adjusting her hips to receive my massive length into her back door.
"Huuuung, ah-hung, aha-♥ It feels so good-."
'Noona, don't make noise!' I scolded her, keeping my voice as low as possible. Youngsun nodded, but it only lasted for a moment. As my forearm-sized cock tore through her anal flesh and pushed in another five centimeters, she let out sweet moans again.
"Ha-ang♥, hee-it♥, it's, so, good-ah-♥, I wanted, to be treated like this with my ass-♥"
How on earth did she develop such a perverted fetish? I was currently breaking in her anal virginity and having my way with her, but I couldn't help but be curious. I'd have to listen to the recording later to see what happened. I thought about that as I pressed the middle finger I’d used for the Vaseline against her lips.
"Noona, keep this in your mouth. If you moan one more time, we're done for today."
Youngsun’s eyes widened, and she nodded in surprise. After a moment of hesitation, she took my glistening finger into her mouth. "Ah, record your face with the selfie camera."
I obediently set the phone on the tray and started recording. It was a vlog-style angle. Even just seeing her lips lightly biting my finger looked lewd, but if you looked closely, you'd notice something strange. Every time a shadow moved behind her, her expression twisted subtly. She let out rhythmic sighs, and suppressed moans escaped from her clenched lips.
'Her expression is... so lewd...' Youngsun was getting even more aroused watching her own face. I could see her eyes glazing over every time I thrust into her ass. The video showed no direct evidence of penetration, but anyone who saw it would call it a hardcore pornographic film. That was how obscene she looked in the video.
Sticky saliva flowing between her Vaseline-coated lips. My finger moving back and forth, embedded in her plump lips. Her forehead furrowed as she couldn't hold back the pleasure... Anyone would think she was climaxing while having a finger shoved into her pussy.
'Kangmin-ah... do it harder, do it harder-' She reached back to grab her cheeks and pulled them apart. Her well-shaped buttocks, toned from 100kg full squats, spread wide, making it easier for her to take my cock. Thrust, thrust. Being fucked in an anal wall that had melted into submission, feeling no resistance, made it feel like moans were going to spill out uncontrollably. She bit down on my finger desperately, trying to hold back the moans. The sensation of being tormented in both her anus and her mouth was divine.
'Noona, you're really lewd today...' I was awakened by the new pleasure transmitted through my finger. My cock inside her ass felt great, but the pleasure my middle finger received was beyond imagination. When I pushed deep into her anus, Youngsun sucked on my finger desperately. It felt like she was sucking the tip of my cock with her mouth. I felt a sense of unity between my fingertip and my cock. Youngsun was probably clumsy at fellatio since she'd never done it before, but she knew how hard to bite a finger without hurting it. And since it was a much sturdier part, it was safe to suck and bite intensely. Realizing this, Youngsun tightened her ass and performed fellatio on my finger.
It was clear I was enjoying it. When she teased my finger with her tongue, my cock, which was fucking her anus, throbbed even harder. The more devotedly she served me, the greater the pleasure in her anus became.
'Ah, it feels so good. Please. Please. I'll do better. I'll do better, so fuck me harder-♥' She drooled from her mouth while sucking my finger. My cock grew stiff and thick. Her already dilated anus stretched to its limit, scattering pleasure deep into her ass and along her spine. Her upper body, which was serving me, was already soaked in saliva up to her neck. The sports bra she wore under her windbreaker was drenched in saliva. Her whole body was soaked in sweat, saliva, and vaginal fluid-.
Youngsun let out a breathless sigh and looked at the recording phone. The woman in the screen had an obscene expression she had never seen before. An obscene woman giving her all to suck the finger that was fucking her ass. While at the same time, writhing in pleasure as she accepted a forearm-sized cock into her anus. That was her true essence-
"Ung-git, un-giiiiiit-♥" Even though I hadn't started fucking her anus in earnest yet, a light climax ran through her belly. In the end, the most important thing during sex is how mentally aroused you are. Youngsun’s womb was like a burning gas station. And every time she realized how perverted she was and what strange fetishes she had, more oil was poured onto the fire. Seeing the video I told her to record, a fiery heat swept through her body. It was a sensation as if her womb were melting. As I pounded the back of her melting womb with my cock, a dizzying pleasure surged up.
To feel it even more intensely, Youngsun spread her anus with her hands and tightened her rectum. My cock pushed through her tight anal walls... With nothing to catch it at the entrance, I thrust even more roughly. Youngsun rolled her eyes back and let out a moan. She put even more strength into her mouth, which was sucking my finger. Ah, ah. Fuck me a little harder, I think I'm going to come-!
'Ah, Youngsun-noona's ass, it's really gripping me tight...' It was a sensation quite different from when I was with Yerim. Back then, it felt like my cock was being softly pressed by silk fabric, but now, it was like gripping and shaking a tight onahole. Using a lubricant with absolutely no moisture like Vaseline created incredible friction. It would be quite sore for both of us once I pulled out, but right now, it was an extremely sharp pleasure. In particular, the emotional satisfaction made my pre-cum leak out uncontrollably.
It was the second day since Youngsun-noona became an anal non-virgin, while keeping her pussy a virgin. It was a fetish that would make an ordinary person freak out, but Youngsun-noona was getting aroused, soaking her pussy. If I teased her pussy with my fingers at the same time, she would probably climax within four or five strokes.
'But I'm not going to touch your pussy.' It was teasing, but it was so thrilling that Youngsun-noona, who was usually so kind, was held in my grasp and offered her ass without resistance, even when I told her I'd break her virginity later.
I watched the point of connection as our bodies collided with slapping sounds. Her pink anus was glistening with Vaseline and stretched to its limit. I deliberately pulled my hips back, and her anus opened, gasping. Youngsun-noona, having lost my cock, moaned longingly. I shoved my thick cock back into her wide-open anus. I didn't maintain the insertion. I pulled it out of her anus, admired her relaxed sphincter, and shoved it back in. After repeating that a few times, a long string of pre-cum and intestinal fluid stretched out. I felt an excitement that made me feel like I was about to cum. Right now, the inside of Youngsun-noona’s rectum was being churned, mixing Vaseline and pre-cum. I was going to add my semen to this and dump it all inside.
'Noona, I'm going to cum. Tighten up.'
Hearing my whisper, Youngsun nodded violently. 'Me too, I think I'm going to come too-♥♥♥♥' Because her mouth was blocked by my finger, she expressed it with actions instead of words. She shoved my middle finger deep into her mouth, swallowed my saliva, and tightened. She tightened her anus with all her might, as if squeezing it with her hand- Ah, it's coming, it's coming-♥♥♥♥♥♥♥♥
Gush, gush, b-r-r-r-t!!
Yogurt-like, thick semen poured into Youngsun’s rectum. Youngsun also rolled her eyes back at the forbidden pleasure coming from her anus and trembled violently. Vaginal fluid flowed from her pussy, soaking her hair, and since her hair couldn't absorb it all, it flowed down her thighs. Even so, her mouth continued to suck my finger to avoid letting out a moan. Both of us were swept away by an intense climax, unable to regain our senses. A long while later, we both panted for breath. As the storm of intense pleasure passed, a sense of exhaustion dominated our bodies. The first one to move was me.
