Their Eggs by Mipsy for travastila, I_want_a_coffee

Summary
It was only when he was spooning Spamton, knot deflating and hands rubbing his starry sky’s stomach, that he accepted the obvious. “I think you’re pregnant, Spammy.”
“So you’re finally acknowledging it?” Spamton snarked.
“I thought that they’d dissolve, Spamton. I promise. I didn’t do this to you on purpose.” He nuzzled Spamton’s hair.
“It’s okay…” Spamton sighed, leaning back against Tenna’s chest. “It’ll all be over soon enough.”
The eggs stuck. Spamton’s pregnant after Tenna’s rut, and he is NOT taking the situation well.
This fic takes place after chapter 14 of “The Beast You’ve Made Me” by I_want_a_coffee.
PLEASE heed the tags. This fic deals heavily with gender dysphoria and self-harm.

Summary
This is a fic covering the Champions Island event for death battle champions, following a personal plot, interactions, arcs, ships, and an elimination order I came up with myself. So, it doesn't follow the elimination order of the actual Champions Island. The earlier chapters are more like one-shot interactions between the 16 characters that bounce around different dates and time early on in the game. I promise future ones will have a more natural structure to them.

White light shines through the mosaic windows, and Greek pillars border the corridor in both sides Mami, Sayaka, and Madoka are cautiously walking in the middle of the hallway to reach the end, until they stop as a girl with long black hair like Homura with slightly pale skin and has black eyes with white pupils made herself known appearing from a pillar and was wearing her seemingly signature blue hoodie with a gray hood, a white t-shirt underneath, black shorts with white stripes, and a pair of white slippers and was showing her signature smile to them.
"..."

"..."
"Well, i won't grace it with a description. But damn this is your 900th try so good luck. Kyoko and Nagisa are waiting for you three, you know?"
"S-Sachi-san please we can try and talk this out-". Before Madoka can finish what she's saying, Sachi Akemi looked her with her white pupils missing.
"Talk this out?" Sachi scoffed "You lost that chance after what you did to Homura" -
