So, this is something a little different for me. The Isane picture I got from Axel could be taken as either pregnant or just belly/boob inflation. This is obviously pregnancy, and I went to RiddleAellinea on DA for it. Simple, but effective. I did just notice Isane's eyes aren't her normal color for some reason, I might try and fix that. Story idea here, something like this.
Isane has volunteered to undergo an artificial pregnancy, in order to help out her beloved captain. Little did she know that Rangiku's DNA was the one used as the 'father', so to speak. This helped her get pregnant, but far beyond what they expected. She's still not quite full term, she's looking at at least four kids. Rangiku's hoping for an even half-dozen, with at least one boy she can name Little Shiro. To help give the kids a stronger bond, Isane and Rangiku spend more time together, and bond to the point that Rangiku moves in with her, showing a completely different side to her normally lazy demeanor as she helps take care of her gravid lover. Though, by this point, Isane is mortified of going out since she's so big. Nothing fits her anymore. Rangiku doesn't want her to feel left out, and heads to the the Science Corps for a few changes of her own. She surprises Isane with a naked cuddle-hug, and helps give Isane the confidence she needs to go and find some new sexy clothes.
