Seven-Sins-Avenger 309

Chapter 309 if? – Honoka Netorase – The Front Side*


Edited by: Kanaa-senpai


 Basically, any chapter with “if” in the title is a world where Aurelia is not involved. However, it is a different world from the previous chapter.


 ===


 ”Hey, Honoka.”

 ”What is it, Susumu?”

 ”Do you know what netorase¹—cuckolding—is?”


 My boyfriend, Koganei Susumu, suddenly blurted that out. It’s been over three years since we started dating. Our relationship is… well, I wouldn’t say it’s bad. We’re both college students now; we go to the same university, but since our majors are different, we never run into each other during lectures. By the way, Susumu is still playing baseball. Unlike Akiyama-kun, who went pro, Susumu didn’t get scouted by anyone, but it seems he still can’t give up on his dream.


 ”Yeah, I know what it is. What about it?”

 ”Honoka… would you do an NTR thing for me?”

 ”Pffft—!?”


 I choked. What on earth is this man talking about?


 ”No, look, I’ve been having s*x with you for three years, Honoka, but lately things have gotten into a rut. It’s like, it just lacks a bit of stimulation.”

 ”So why does that lead to NTR!?”

 ”Because your reactions are just ‘meh’ lately. I want you to be held by some other guy, record it, and show it to me. Just imagining you getting all disheveled while being held by someone else… it gets me so excited. So please! I’m begging you!”


 Susumu put his hands together and pleaded. (Well, if it makes Susumu happy, I guess it’s fine.)


* * *


 A few days after Susumu suggested the cuckolding, we were in front of a certain love hotel. Susumu was there with a man I didn’t know. The man was of average build and height, with his eyes hidden by his bangs. Aside from that, he looked like any ordinary guy you’d see anywhere. Dressed in a casual suit, he wore a soft smile. He didn’t look like a bad person.


 ”Nice to meet you. I’m Natsumi Shiro. Nice to meet you. So, Koganei-kun, I just have to hold your girlfriend, right?”

 ”Yes! Shiro-san, she’s already consented!”


 Susumu seemed excited. However, when did he get to know this guy… Shiro-san?


 ”Narumi-san, shall we go?” said Shiro-san.


 Shiro-san wrapped his arm around my waist and led me into the hotel. A woman was standing at the counter. She had a bob cut and cat-like eyes. “Lia, I’m counting on you for today’s filming,” Shiro-san said.


 ”Leave it to me. I’ll film something so lewd it’ll put adult videos to shame,” Lia replied.


 ”I am Kurusu Lia. Nice to meet you,” said the woman. I shook hands with her. Why did I feel like I was looking at myself?


 ”I’m Shiro-san’s (Master’s) lover (s*x slave),” Lia added.


 (Wait, did she just say ‘s*x slave’?) I couldn’t quite catch the last part. We entered the room. Shiro-san sat down beside me, and Kurusu-san started the recording. “Alright, let’s begin. Koganei-kun, I’m going to hold Honoka-chan now,” Shiro-san said.


 ”Um, Susumu. Watch closely… while Shiro-san holds me. Don’t you dare look away,” I said.


* * *


 It had been five hours since they entered the hotel. I was waiting at my apartment. Ding-dong. The chime rang. It was Honoka. Her face was flushed.


 ”Welcome home, Honoka,” I said.

 ”I’m back. Let me in. I’ll explain while we watch the video together,” Honoka replied.


 I inserted the SD card. On the screen, Shiro-san and Honoka were kissing. Mmm, chu, slurp…


 ”You know, Shiro-san is really good at kissing,” Honoka whispered as she started unbuttoning my pants. In the video, Shiro-san exposed a massive d**k. It was twice my size. Honoka timidly kissed it. Lick, slurp…


 ”Honoka, this is how you do a b**job!” Shiro-san said. He grabbed her head. Gulp, choke, slurrrp! Shiro-san performed irrumatio², forcing her to take it deep. Then he came. Splat! Squirt! Seed covered her face.


 In the next scene, they were on the bed. “Alright, I’m coming in,” Shiro-san said. He pushed inside. “Ah! It’s hitting the very back! I’m c**ming from a huge d**k that isn’t Susumu’s!” Honoka screamed in the video.


 ”I’ve become Natsumi-san’s personal meat toilet³ now…” the Honoka on the screen said while making an ahegao face and double peace signs.


 I finally e**culated. Splurt! “Did you get that excited?” Honoka asked. “Yeah. But the ‘meat toilet’ line…” I stammered. “That was just an act. The only one I love is you, Susumu,” she said, kissing my cheek.

 ”Hey, Susumu… should I do another cuckold session for you?” Honoka asked afterward.

 ”Eh?”


 ===


 (Afterword: Sugita’s absence in this ‘if’ world changes everything. He’s currently on death row in this timeline too, but his early removal prevented the bullying of Natsumi and others. Reika and Satsuki have a warped M/S relationship, and the rest of the class is relatively stable. Sugita really is the root of all evil.)


 —


 Summary:


 In an alternate ‘if’ timeline, Susumu requests that his long-term girlfriend Honoka participate in a cuckolding (NTR) scenario to spice up their ‘stale’ relationship. Honoka reluctantly agrees and is filmed being violated by a stranger named Natsumi Shiro and his assistant Lia. Afterward, Susumu is deeply aroused by the footage, leading to a warped continuation of their relationship.


 —


 Trivia:


 - Honoka’s feeling of ‘looking at herself’ when meeting Lia hints at a potential thematic or character connection between the two women that transcends this specific timeline.

 - Susumu’s insecurity regarding his failed baseball career is the underlying psychological driver for his desire to see Honoka with a ‘superior’ male.

 - Shiro’s disclaimer of ‘no responsibility’ suggests a predatory or detached nature despite his polite facade


 —


 Character Insight:


 The core dynamic shifts from a stable, albeit boring, college romance to a fetish-driven arrangement. Honoka’s transition from hesitation to performing the ‘Meat Toilet’ persona for the camera suggests a fast descent into the role to please Susumu, evidenced by her final line: “Should I do another cuckold session for you?”


 —


 Lore And Worldbuilding Context:


 The ‘if’ world-building establishes that Sugita is the ‘keystone’ of misery; his early arrest prevents Natsumi’s suicide and several other tragedies, though it ironically leads to this specific degenerate scenario for Honoka and Susumu.


 —


 TL Notes:


 The author uses this chapter to explore character fates in a ‘Sugita-less’ environment, highlighting how the absence of one villain doesn’t necessarily result in a ‘pure’ world, but rather different types of deviancy.
