[NSFW Alphabet] Isaac / Iris

Important note: Since using a single letter of Isaac/Iris's name may cause confusion during reading, the alphabet will label their name as "[ I ]" in most sentences.

This should help to maintain clarity and a smooth flow, as simply using "Isaac/Iris" could lead the reader to automatically read both names at once, which would likely disrupt the flow of most sentences.

Another important detail to mention: Unlike other ROs, I's alphabet is focused on "dominance / submission" when referring to dynamics rather than the game term "assertive / reserved", as it makes more sense in their case.

The alphabet template is sourced from here. I hope you'll enjoy reading!

A = Aftercare [what they're like after sex]

In general, [ I ] will be very tender, calm, and sleepy, though additional aftercare may require more time and effort depending on how the sex went.

You can read the rest in the "Kink" and "Zzz" section.

B = Body part [their favorite body part of theirs and also their partner's]

Someone's body and appearance aren't something that can attract [ I ] on their own, as it's the mind that captivates [ I ] first.

However, this captivation inevitably leads to physical attraction, so the MC shouldn't doubt that [ I ] likes what they see... immensely.

A part of them would feel tempted to draw the MC naked, but they won't, as they wouldn't want to share what's supposed to be only for their eyes—even with paper.

Still, it would be a lie to say they don't have a purely physical aspect they enjoy, as there's something addictively pleasurable about the slow, deliberate exploration of forearms, hands, and fingers.

While it's satisfying both to receive and return such a touch, it might first appear otherwise [as it happened in Chapter 3 Pt. 1] if the MC touches their tattooed arm for a... reason.

C = Cum [anything to do with cum, basically]

This will generally depend on the MC's preferences, but if it's sex that resulted from an argument… then definitely inside.

D = Dirty secret [pretty self explanatory, a dirty secret of theirs]

[ I ] struggles with intense jealousy, and the MC can exploit this [very carefully, and definitely not during sex] should they wish to see I's needy side more often.

This will work like clockwork, even though deep down, [ I ] will be aware that the MC is doing this on purpose but will be unable [or perhaps... unwilling] to suppress this reaction.

E = Experience [how experienced are they? do they know what they're doing?]

[ I ] is not only experienced but also the only RO who specifically educated themselves on various topics related to sex before practicing, because that's just how they are—always trying to be prepared and have a clear understanding before doing anything.

Though it's been a while since [ I ] has had anything that could be considered more than just a physical release [because sex does help them with that], as they've lost interest in many things in their life, including the pleasure of sex.

F = Favorite position [this goes without saying]

It generally depends on the dynamic:

• If [ I ] is dominant, they would love if foreplay begins with the MC on top, only to switch positions and claim what's rightfully theirs.

• If [ I ] is submissive, they would love starting on top, doing everything in their power to entice the MC into taking control and fully claiming them.

The least preferable positions are doggy-style or any that involve penetration from behind [except for any variation of a spooning position].

G = Goofy [are they more serious in the moment? are they humorous? etc.]

An unreadable expression at the beginning.

Too focused on the MC during the foreplay.

Completely loses control, becoming almost feral / desperate once both are ready for more.

Turns tender under the MC's presence that fills the emptiness left by something that was broken free.

Shifts into intensity once again, trying to match the love they feel.

Shudders completely as the sweet release arrives.

H = Hair [how well groomed are they? does the carpet match the drapes? etc.]

Overall, everything is well-maintained, both visibly and underneath the clothes, so whether it is completely shaved or neatly groomed is a matter left to the reader's headcanon.

Bonus specifically for Isaac: 

Yes, there will be moments when the MC can see him with stubble. And touch it. And feel it trail lower to—

I = Intimacy [how are they during the moment? the romantic aspect]

[ I ] is a natural switch, but this adaptability comes from life experiences that have reinforced an inherent trait rather than a conscious preference.

However, the more they spend time with the MC and learn their preferences, the more they will start to lean toward a certain dynamic [in romantic and sexual interactions], either dominant or submissive.

This shift won't come from a desire to please the MC and "be perfect for them" [though that's an undeniable bonus], but rather from the comfort of staying in a particular role instead of exhaustion from constantly balancing everything.

You can read the rest in the "No" section.

J = Jack off [masturbation headcanon]

It would be better to experience what [ I ] does now if they masturbate more often, as [ I ] is a person for whom sex provides a release of both physical and mental strain.

K = Kink [one or more of their kinks]

It's hard to call it a kink, but… angry sex.

If it comes to an argument, the MC can be sure that [ I ] cares deeply, because they usually don't see the point in wasting their breath on people they don't care about.

And once tensions run high and emotions reach their breaking point, if [ I ] steps in close but suddenly falls silent, it won't be a pause for thought but a clear sign that they [choose depending on the dynamic]:

• thinking about fucking the MC.

• want the MC to fuck them.

Senseless.

This won't settle the argument [which will be discussed more calmly later], but that kind of sex will inevitable leave traces, both on the interior and on the MC's and their bodies—and they will hate it.

Why is loving someone capable of causing so much harm?

They will insist on taking care of them and will feel guilty, even if the MC finds pleasure in them.

The MC can absolutely take advantage of this, enjoying the careful way [ I ] will trace them, telling themselves they should be more careful—only to fail because of what being careful with the MC means for them.

As for the marks the MC can leave on I's body, [ I ] definitely won't tend to them but will feel conflicted for... a reason.

L = Location [favorite places to do the do]

For [ I ], sex is something that should happen behind closed doors, away from unnecessary eyes and ears, allowing them to have their time with the MC and focus on the process.

Although initially, even the right time and place won't be enough to make [ I ] do so entirely: too much suppressed tension ready to burst, too little information, too many opportunities for mistakes, too much exhaustion to be careful, too strong desire to resist the MC and the want for them…

Learning how to handle all of this will take effort, but given that [ I ] is generally an eager learner, it won't take long to figure out how to harness their complicated longing into pure pleasure [especially when the MC helps amplify this eagerness].

M = Motivation [what turns them on, gets them going]

The MC taking the polar opposite role dynamic with [ I ]. Everything else will follow from that.

N = No [something they wouldn't do, turn offs]

While [ I ] has a strong preference for either dominance or submission, they have boundaries they will not cross, as their preference for these dynamics is more about the psychological and behavioral control than the emotional or physical vulnerability that often accompanies them.

This is why pegging isn't something [ I ] can enjoy [as it often involves these aspects], and anything related to humiliation or degradation is a complete turn-off for them.

Dirty talk can be an expectation, as [ I ] absolutely can [and will] engage in it with the MC, with the condition that it remains without elements stated above.

The reason is simple: with the MC, they want to be a good boy/girl [even if it's far from true], and they will seek the MC's approval and love, whether by holding the MC's neck and murmuring soft "again" as an order to moan their name, or pleasuring the MC on their knees until they come.

In addition to what's been mentioned above, it's important to note that all ROs are monogamous and extremely jealous. This means none of them would be okay with:

• Sharing the MC with anyone else.

• The MC mentioning or speaking about another person during sex.

O = Oral [preference in giving or receiving, skill, etc.]

This will depend on the dynamic and the MC's preferences and reactions.

However:

• If [ I ] is dominant, they can be pretty rough when receiving, but this can only happen after some practice with the MC, where [ I ] can understand what the MC likes.

• If [ I ] is submissive, they would be more than okay if the MC gets a little rough with them and as [ I ] can [and absolutely will] drag out the pleasure purposely to provoke the MC for it.

Also, they wouldn't enjoy 69, as they would want to watch the MC pleasuring them / the MC watching their mouth work.

P = Pace [are they fast and rough? slow and sensual? etc.]

[ I ] is passionate, focused, and a perfect balance of roughness and tenderness.

Q = Quickie [their opinions on quickies, how often, etc.]

Once [ I ] settles their mind and body into sex with the MC, nothing else will exist for them in that moment. Therefore, if things start to get heated, it will either:

• Stop if it's not the right time and place, with [ I ] giving a hard and passionate kiss that will turn tender before they pull away as a promise to continue later.

• Grow into a full session so [ I ] can take the MC / give themselves to the MC the only way they deserve: properly.

R = Risk [are they game to experiment? do they take risks? etc.]

Being careful and observant from a distance is generally a significant part of I's personality, which is why their behavior initially seems so unassuming and neutral.

And even after they start to lean toward a certain dynamic, it will not go beyond "safe territory" [more or less vanilla] unless [ I ] notices the MC's desire and discusses it with them, because some habits are too deeply ingrained to simply die.

S = Stamina [how many rounds can they go for? how long do they last?]

I's exhaustion runs deep, affecting both mind and body. Combined with their tendency to lose themselves completely in sex and be fully focused on the MC [to the point where nothing else exists], one intense but extended round is usually all they are able to offer.

T = Toys [do they own toys? do they use them? on a partner or themselves?]

[ I ] considers toys [or any other sex-related accessories and equipment] useful tools that can help achieve a desirable effect, but they don't view them as essential [unless it's for BDSM or a specific roleplay sessions].

Plus [given what was stated in the "Experience" section], it's been a long time since they last used them, and whether that will change and how will depend on the MC's preferences, as the MC will be the one for whom [ I ] is willing to put effort into this regard [or sex in general].

U = Unfair [how much they like to tease]

It's difficult to assess someone's sense of unfairness when they softly promise you they'll cook you breakfast and then fuck you / tell you to fuck them hard in the same sentence.

V = Volume [how loud they are, what sounds they make, etc.]

It depends on the dynamic:

• If [ I ] is dominant, they become more talkative, in a most tender manner… in contrast to their actions.

• If [ I ] is submissive, they may intentionally stay silent, provoking the MC to push harder until they have no choice but to give in.

Small bonus: If it's sex about releasing emotions or tension, it's anything but words.

W = Wild card [a random headcanon for the character]

While it won't be explored in the main story, if the MC is also a switch, it will create an effect where it would be more difficult for [ I ] to feel compatible with the MC.

The same will apply if the MC would want [ I ] to stay in a switch role, as the residue of what it used to mean won't allow them to enjoy it.

X = X-ray [let's see what's going on under those clothes]

Overall, I's body structure indicates that they shouldn't appear as worn down as they do now, and the MC would likely be able to feel the contours of their ribs and spine if the MC traces their fingers along their back.

Still, the most delicious parts of their body have been spared from this condition.

Bonus specifically for Iris: She has the largest breasts among the female ROs, and it would be entirely understandable if the MC developed a habit of using this part of her in the same way one might use an anti-stress toy.

Y = Yearning [how high is their sex drive?]

As mentioned in the "Jack off" section, [ I ] is someone for whom sex can serve to relieve tension, and since they carry quite a lot of it [given how controlling and restrained they tend to be], it's both a necessity and a torture for them to "take things slow" at the beginning of their relationship with the MC.

This is why they might seem overly forward one moment, only to withdraw the next. A part of them feels guilty because they know this isn't fair to the MC, but another part desperately wants—needs—to give in.

However, the more they interact with the MC, the more stable and steadily assured this yearning will become, so their need for sexual activity will naturally and eventually align with the MC's needs and desires.

Z = Zzz [how quickly they fall asleep afterwards]

The moment the breaths slow and the necessary aftercare is done, [ I ] will immediately settle into a cuddling position and drifts off to sleep.

Being so relaxed around someone—and because of them—is dangerous, but the MC will awaken I's long-forgotten desire for it, and they would rather embrace all the potential risks than let their caution make their everything slip through their fingers.
