Arachne's First Backdoor
"W-wait a second? At this size, shouldn't we prepare properly first, uwaang?"
Thud! I grabbed the waist of the girl who was yapping like a small dog, flipped her over, seized her hips firmly, and pulled her toward me. A perfectly satisfying position presented itself right away.
"Ung... ah, the drawer by the bed... there's lube in there...?"
I ignored her desperate reach for the unreachable drawer and decided to cool down the heat of my own manhood first. Schlurp...!
"Ah, the front...?"
No matter how worked up I was, I didn't shove it straight into her rear hole. I found the familiar entrance I knew so well, but the sensation was definitely different now that my size had changed. Maybe it was just because it had been a while, but the feeling of filling her all the way to the depths with that tight resistance was incredibly satisfying.
"We've got natural lube right here."
"Ung, uwaah... hwaak...?"
Thrust, thrust... schlurp. Shluuurp, bwop...!
"Uuu... too much..."
I gave her a few deep thrusts just to cool off and coat myself, then pulled out with a wet sound. Her mouth complained that it was too much, but her body told a completely different story. I never thought I'd experience the luxury of using a woman's front hole only as a makeshift lube dispenser. If she hadn't teased me into getting angry, I probably wouldn't have done it even if she'd begged.
Anyway, pounding her sloppy hole from behind like this would feel amazing, but since she'd gone to the trouble of preparing, she'd probably enjoy it more if I used the place she'd readied for me.
"You've got so much fluid. Thanks to you, cleaning up is going to be a pain."
"Kyaaang...?"
I shifted my grip from her hips to a more comfortable hold on her front, then brought the glistening tip of my cock to the unfamiliar entrance. I'd seen this view plenty of times during doggy-style, but now that my manhood was thicker than the largest bead on the toy she'd been using earlier, I couldn't help wondering if it would actually fit. Anticipation and concern mixed together.
"Huu..."
Anal sex. I knew a surprising number of people did it from behind, but this was my first time actually trying it, and for some reason that made the excitement even stronger. The pretty pink anal wrinkles, already glistening with lube from playing with the toy, were twitching invitingly. If I just pushed forward, it felt like it would slide right in.
"...I'm putting it in."
"Yes... Master... Please take my backside for the very first time... all of it..."
The sight of her raising her hips and wiggling them as if offering her lower body for me to use however I wanted made the base of my shaft throb powerfully.
"Hikyaang...?"
The act of rubbing against those slick anal folds sent another jolt of excitement through me at her vulgar moan. The sense of taboo at putting it in an excretory hole. The knowledge that she had skipped meals and even given herself an enema she would normally hate, all for this... even that troublesome effort excited me now.
I wanted to impregnate this female no matter what. I wanted to make this woman feel good. I wanted to turn our precious relationship into happy memories. That was why I was this hard. Not for any other reason.
"Haha..."
"Master... hurry..."
I was this erect purely because I wanted to know what kind of pleasure I could get from this new hole. Yet she was looking up at me with an expression no normal girl would ever make, clearly hoping I would pierce her anus with my cock. It didn't feel wrong at all.
"You... perverted bitch."
Push... stretch...!
Unlike what I'd expected—that only the glans would slip in easily—the very tip slid inside without resistance, then caught at the ring of muscle. Every single fold of her anus became vividly clear as it clenched tightly around me.
"Huu... eup..."
"Uuu... aaah...? Aaaang...?"
Schluuuurp...!
Timing my thrust with her ragged breathing, I pushed harder when her muscles relaxed. The glans slipped inside smoothly. The toy covered in lube had already loosened her up quite a bit, and coating myself thoroughly with her own fluids beforehand had helped.
"Ugh..."
The thought of ignoring her perfectly normal front hole to fuck her ass instead made me self-conscious about moaning, but when the sensitive underside of my glans was squeezed by that tight ring, my legs almost gave out and a sound escaped anyway.
Schlub, schlub...
Once the head was in, the rest followed without much trouble. I just had to push forward along the shaft. The entrance clenched like it was trying to strangle me, but the inside was soft and slick, letting me sink all the way to the base with satisfying ease. This... was going to feel incredible to pound.
"Ah... uuaa, ah..."
Even though she was face-down, her front hole had been pressing against her cervix before I was fully inside. This time, however, I sank all the way to the root with relative ease. For such a small body to be able to take my entire length... the sense of security it gave me was beyond anything I'd imagined.
"Ugh..."
"Ah... ugh, huuu... hwaaa..."
While I was savoring the pleasure, she seemed to be struggling with the sheer size filling her. She was trying to breathe slowly through the overwhelming sensation, and every time she inhaled and exhaled, those anal wrinkles tightened and loosened around the base of my cock in the most fascinating way.
"I want to start moving."
"Ah... ugh, ...yesh... move...! Hiss, ugh..."
'This... is different... It's nothing like the toy... It's too big... I'm going to die... I'm going to break...'
"You were the one who seduced me first, so don't start whining. Keep your hands steady. If you slip while I'm pounding you and actually tear, that's on you."
"Auuuhaa... ah, I don't want that..."
"Neither do I. I plan on using this hole regularly from now on."
Even as I said it, I wondered if I'd gone too far, but the sight of her trembling legs and the clear fluid dripping down between them told me she was handling it just fine.
Schluuuk... schlup... schlup... schlup...
The way her anus squeezed... damn. It was on another level compared to the front.
"...Huu... haa..."
"Ah... ugh... haat, ughk..."
The sensation of moving inside was addictive, but she still looked overwhelmed. No matter how much she'd prepared for today, the gap between practice and reality was huge. I didn't want to enjoy it alone, so I reached down and found her dripping front.
"Gyahk...? Ah...! Ah?"
When I rubbed my fingers along her slit and pressed firmly around her small, protruding clit, her reaction improved immediately. Her legs were still shaking, but her moans started to carry a sweet edge instead of just strain.
Schlub, schlurp... shluuurp...
"Huuuu..."
This sensation was completely different from the front. The fact that I was inside a hole a normal girl would hate and refuse, all because she'd begged me for it, pushed my climax dangerously close. Thinking back, everything I'd done with her—cumming on her face, deepthroat, spanking, even choking her neck—things I once wondered if they were okay to do to another person... this girl had made me try all of them. And today, finally, anal sex too.
"Ahk, hyak... hwaak... hak..."
I glanced at her face while moving my hips at a leisurely pace and teasing her clit. She looked completely wrecked—sweat-soaked, mouth hanging open, drool running down her chin without a care.
"Usually, huff... girls at least pretend... hah... to look pretty, you know."
"Hyaaak...? Hak... hwaang, ahak... haaang?"
Schlub, schlup, schlup, schlup...!
I wasn't even moving that fast, but the excitement of my first anal experience had my orgasm rushing up fast. My breathing grew ragged and hot sweat rolled down my forehead.
"Ah, damn... what kind of grip is this..."
Stimulating her front had loosened her rear a little, but it was still gripping me all the way to the base with relentless tightness. I couldn't hold back much longer.
"I'm going to cum... hah, right inside...!"
"Ahaak? Ah... aeuang...?!"
I leaned over her, shortening my thrusts into quick, shallow movements to chase the peak. The true value of anal revealed itself.
Schlub, schlup, schlup, schlup, schlup...!
"Ahk, hak...! Hyat, hyak...! Hak... haang?!"
The way it milked me at the moment of climax was incredible. This hole satisfied the urge to give the strongest possible stimulation right when I was about to finish.
"Kyaaahk...?!"
When I carelessly shoved my thumb into her front hole while still playing with her clit, her anus clamped down like it was trying to bite me off. In that instant, I knew—cumming right now would feel absolutely incredible. I slammed my hips forward, threw my head back, and arched my spine.
Spurt, spurt, spuuurt...! Glrk, glrk...! Shluuurp, spurt...!
"Ugh... haaaaa... uheooooooo..."
Cumming inside without any worry of pregnancy. Even though it was my first time in this hole, the spine-tingling pleasure was so intense it felt like my soul was being pulled out. Thick ropes of semen painted her insides in powerful pulses.
"Uuu... uuuu... hueee..."
Only after I'd finished thrusting and cumming did I truly feel the warmth inside her. The way she squeezed around me was different too. Those anal wrinkles that had been frantically clenching now showed their presence even after climax, rippling along my shaft in the most satisfying way.
Schluuuuuurp... pop...!
When I finally pulled out, following the still-clenching ring to squeeze out the last drops, her anus stayed stretched open wider than the toy had left it. Thick, white semen slowly leaked out, steam rising from the heat.
"Hah... hah... hah..."
What an addictive hole. The thought came before I even worried whether it would close properly again. It had felt that good. So this was what it was like to feel this much pleasure from a woman's ass...
A rough laugh mixed with a sigh escaped me.
"Hah... hah... Master... did you... feel good...?"
"Yerin, you..."
"Did you like... my backside...?"
"Hey, wait a second...?"
The moment I pulled out, she finally caught her breath and somehow managed to lift her collapsed body. She stared blankly at the considerable amount of semen flowing from her anus. Then, still struggling to support herself, she crawled over to my cock and brought her face close.
"...Hey, you... that's the thing that was just in your ass..."
"Mmm... slurp... chuup..."
"..."
She started giving me a cleaning blowjob like it was the most natural thing in the world. Even though Undine had cleaned it once already... that hole was still... insane...
"...? Hup... slurp... chup..."
She looked up at me with that innocent face, as if asking what the problem was, while her mouth was busy with the very cock that had just been pounding her rear hole moments ago. All I could think was that this girl was seriously something else.
