Oohh Velo I’m so glad you asked because I’ve been thinking about it ever since you sent it and it’s delicious brain food.
This got a bit long, but I don’t think you’ll mind : 3

It’s so… there are so many ways this could go, right? But let’s say that in this one, they’ve been living together for a few months and this is Dante’s first long trip since Eiden moved in. Eiden looked a little sad to see him go… but Dante is built different, he has a job to do, a purpose, he can’t be thinking about that man all day. How pathetic would that be? Dante is only thinking of him on the way there because he’s entrusted Sooley in his care, that’s not the same. And he lets him know he got there safely only so he doesn't have to recall his worried expression anymore. How troublesome.

Eiden is the one who initiates their text exchanges. Since they live together, they don't text much but, just like they acclimated to their current living arrangement without too much trouble, they quickly settle in their new routine without having to talk about it: Eiden sends him a good morning text, then random pictures throughout the day, to which Dante replies with a few words, then they do a quick call before bed.

I’m picturing Eiden sending a pic of Sooley sleeping under their bed covers, just a round shape protruding from under the sheets.

Eiden: He’s sleeping on your side of the bed too 🥺
Dante: …Why would he do that?
Eiden: Because he misses you! Your scent is the strongest there.
Dante: Stop smelling our sheets.
Eiden: Wha—?! I don’t need to smell them to know that!!

And this exchange plants this idea in Dante’s mind that when he’s not around, he is missed. And not only in a way that’s expressed through simple words typed absentmindedly on a bright screen. It’s also physical.
The thought lingers on his mind all day. He gets shivers when he hears Eiden’s voice that night. He’s half-listening through Eiden telling him about something funny that happened at work that day when he asks Eiden to turn on his camera too. He gets shivers when he sees that bright smile on the screen.
Eiden, of course, gets very inquisitive about his sudden request. Dante brushes him off, explains he just wanted to test something. Eiden knows he’s not being entirely honest but that’s ok, he’s used to slowly prying little pieces of truth out of him.
Their text exchanges start to change.
Eiden is flirtier, more upfront about missing Dante. During his lunch break, Dante sees that Eiden sent him a picture while he was in a meeting. He quickly opens it, expecting to see Sooley… instead, he almost chokes on his salad. He reprimands Eiden right away who laughs it off. It's just a little treat to keep him going until their call that night~
Dante is scandalized, of course.

SO ANYWAYS, THAT NIGHT.

Dante only agrees to a voice call, which Eiden doesn’t mind; he can work with that. He tells Dante how about he’s half naked under the sheets on his side of the bed; as it turns out, it does still smell like him. It’s like Dante is here next to him but not really. There is still so much that’s missing, that he’s been missing, and Eiden tells him in excruciating detail while Dante listens lying down in his own bed, phone resting on the pillow so his hands are free. After, Eiden explains that usually, since Dante has a tendency to pin him down and fuck him so hard he can’t keep quiet, he never gets to hear Dante’s voice properly. So tonight, having his deep voice, his laboured breath right next to his ear... it was nice.

Eiden would keep sending saucy pics once in a while, never when Dante expects them. They’d escalate to video calls soon after. Eiden being Eiden, he would absolutely prepare some toys for the occasion, including an oddly familiar looking dildo. Dante doesn’t want to know how Eiden got his measurements so right, down to how the veins trail along his shaft. But there is something he must know.

Dante: …Why is it purple?
Eiden: I didn’t want you to think I was actually replacing you 🥺
Dante: (What kind of logic is that...?)

You can work out how it went from there 😁 When Dante comes back from his trip, they make up for lost time. And do the laundry.

And that’s it, I think, since this one is getting pretty long already and I have to go to bed. But I hope you liked what I came up with! : )
