Like they're at a bar and some random is hitting on a clueless Siffrin who wouldn't know if someone was hitting on them even if it smacked them in the face. And Loop is just #Seething™️ in the corner like: Someone flirting,,,,with MY Stardust?? In front of ME? Absolutely not. So Loop is in a bad mood and wants to leave, and obviously Siffrin would follow them to the ends of the earth so he's like "Of course!!!" and they leave before Loop can throttle the poor person they've been glaring daggers at for the past 5 minutes.

And on the way back to the inn they've been staying at Loop is just reeling over the audacity that somebody would just flirt with Siffrin right in front of them?? Shouldn't it be obvious that Siffrin is THEIRS and no one else's? They just cant wrap their head around it- it should be obvious but apparently not. That's something that needs to be fixed immediately.

And during this whole time Siffrin is just like- nervously smiling bc they know something is bothering Loop but they don't know whether or not they're just in a bad mood or if was something he did. So they get back to their room and before Siffrin can ask if Loop was upset with them Loop just immediately asks "Do you notice it when people hit on you?"

And Siffrin's Iike: "...People hit on me...?"

So of course Loop goes on this big rant that 'Yes, Stardust, people hit on you allll the time and it makes me seething with a boiling rage!! Teehee!' And obviously Loop knows it's not Siffrin's fault, it's not really him they're mad at. But it doesn't stop them from angrily spouting out how much they HATE seeing people going after Siffrin like he's up for grabs, like he doesn't already have something special with Loop. Something that no one could EVER recreate with him.

During this whole time Siffrin is being hounded against the wall, flushed and overwhelmed bc Loop keeps referring to him as 'theirs' and the notion makes his knees wobbly and his brain mush.

And you know what's the worst part? Sifloop isn't even together yet. So why is the idea of someone else hitting on Siffrin so terrible for Loop? Why does it fill them with a jealous yearning of picturing Siffrin doing something even mildly romantic without them? It's not fair, so obviously Siffrin must answer for this.

So Loop is just holding Siffrin with a tight grip, glaring down at them like "Well, what do you have to say for yourself??" And poor Siffrin is throbbing because Loop manhandling them has awakened something within them.

And then it hits Loop- maybe they need to put something on Siffrin, something permanent that'll drive anyone away from trying to take their Stardust from them. But what?? The idea of jewelry comes up, but that sounds too similar to bonding earrings and that's a can of worms Loop CANNOT get into yet. So what's the next best thing? Something on his skin maybe, like a tattoo or a peircing or maybe...

And without even thinking about it, Loop just surges forward and bites Siffrin on the side of their neck, hard enough that it'll leave a hickey behind. Because if people see this then they'll know how Siffrin is off the market and to back off. Siffrin is THEIRS, Loop made Siffrin from their wish, watched over Siffrin, knows everything about them. Siffrin is their clone, THEIRS.

So Loop just keeps biting and sucking on the side of his neck until it's bruised and marked, Siffrin panting and groaning the whole time until Loop leaves a deep kiss over it and pulls back to look at their work. His neck almost looks like it got mauled by an animal, but it's more than enough for anyone that sees it. Perfect. Loop's job was done.

Right before Loop leaves they give one last warning look to Siffrin and say "Don't even think about healing that" before leaving the room to cool off. And poor Siffrin is just swaying there in place, face burning, body flushed and just fully wet and throbbing bc this is the most turned on they've ever been. They rush to the bathroom and have probably one of the most intense masturbation sessions they've ever had, one hand already in their pants while the other is touching the bruises on their neck.

Siffrin doesn't heal the hickeys, but they do take a shower out of immediate shame and try their best to act cool after getting out and pretending like Loop didn't awaken a side of them. At this point Loop has calmed down, wide smile on their face as they exclaim, "Wow!! Things got intense there for a second! I'm glad we sorted that out, Stardust!!"

Siffrin, who's just had a very vivid masturbation session of having Loop absolutely devour him: "....Yeah, we sure did..."
