Shuuya waddled to his bedroom, stark naked after an early shower, since the twins kept him up for so many pee breaks last night. He looked down at his massive mound, stunned that the babies had not only decided to have a slight growth spurt, as the doctor said would commonly happen, but they had stayed 2 weeks overdue. Struggling to pull on a big t shirt and maternity jeans, getting dressed somewhat reluctantly for the last day of school, the cub’s memory of his last checkup came up.

“You should be having the babies soon, Shuuya, but if you go overdue, don’t behave any differently. Stay calm and let your body do what feels best. This pregnancy is magical, but not malicious. It altered your anatomy and such, so the birth should proceed as if you were a hermaphrodite, since we discovered that change early in the gestation. Just try not to do anything too strenuous and take it easy and the babies will come when they will. And going to school should be fine, since as far as I can tell, you’re not in any danger of a low birth weight and the magical nature will even make birth go smoothly, so I’ve made it clear to the principal that you are in no way a risk to the school’s insurance and standards.  As I said before, just play it cool. If you pop in public, it happens, but the pregnancy will not have complications, especially since you’re such a nice kid to begin with,”
Shuuya smiled and nodded as the doctor helped him off the table and he waddled out to the car where Hanzuke picked him up.

After getting dropped off by Hanzuke at school, he reluctantly began the waddle into school. It was the last day, thankfully, so Shuuya wasn’t as stressed or worked as he was the last week or so, getting exams finished. The babies kicked violently as their ‘mommy’, which he tended to call himself, rubbed both hands soothingly on the sides of his bump to try to keep them from making him pee himself as he waddled as fast as he could to the bathroom. Coming out, he waited in the classroom for the teacher to arrive, assaulted by female classmates, who still wanted to feel the twins move, as well as Rhemora, who was personally given the assignment by the principal to keep watch on the pregnant cub, giving Shuuya a much needed foot rub as class began.
The day went by rather uneventfully, mostly the same last day of school events you’d expect, homework and even classwork all but forgotten as everyone was especially on edge whenever Shuuya came into the classroom or left, concerned that the heavily pregnant lion would pop his cork and go into labor, which was a rumor not easily dispelled even by the  fact that had spread around that he was 2 weeks overdue, not to mention Shuuya letting slip to some of the girls that one of the twins had dropped and now he was having to pee all the more often, which they giggled with him about how he was glad the girls’ bathroom was closer.
After the day was finished, Shuuya bid Rhemora goodbye, after a final kiss and belly rub for good luck, since they were both worried and on edge that the twins could be born any minute now. But the day came and went, only interrupted by what Shuuya could only conclude were Braxton Hicks, the other thing bothering him was a persistent backache, though everywhere ached at this point, so it was mostly ignored by the heavily pregnant cub.
Getting home, Hanzuke gave him a somewhat awkward hug, considering how the twins were between them, kicking outward at the intrusion, however much they were family.
“I think we should get some last day pictures, since I’ve got a feeling you’ll be having these two pretty soon,” he said as he motioned with the camera to his prominent bump.
Shuuya nodded as he posed to the side, one hand on his back, the other on top of his belly. He then shifted to a pose with both hands on his back, which was a welcome relief for a bit as the twins pulled on it so bad now. He then got his shirt off with some difficulty and posed a few more times, then getting off his pants, just in his batman underwear as he began to strike more outgoing poses. Han then suggested he try some more adventurous positions, Shuuya bending over the bed, his belly hanging prominently as he blushed and looked towards the camera
“L-like this, brother?” the cub inquired shyly as Han snapped the pics, knowing they’d be more private than the former ones.
After finishing with pictures, Shuuya grunted at another back spasm, the twins shifting a bit, though they had such little room to do so at this point, the girl that had dropped a week or two ago now pressing on his bladder again as he hurried to pee. Coming back out, he ditched the maternity pants, cooled off a great deal. Since it was so hot, he was nearly ready to waddle around in just his undies, but he usually waited until he was getting to sleep before he almost completely disrobed.
The cub slowly waddled to the livingroom, plopping himself on the couch to watch some episodes of “A Baby Story” he had recorded, especially the one with twins. Getting a bit nervous, the babies started kicking to try to calm their mommy down as he teared up a bit. “I know, little ones. Mommy’s just scared since she’s only just recently realized how much is going to change when you’re born. I love you to death, but I also want to have you in my arms instead of in my belly. Come soon, please?” he requested, the girl at his bladder shifting as he squeaked, hefting himself off the couch to pee. After finishing up, he posed in the mirror, looking at his massive side profile with a sigh. 
“Look how huge you’ve made mommy. Not that I can’t lose the weight quickly, but still…so round, though not so much now that the little princess has dropped and makes mommy have to pee all the time,” he said with a chuckle.
Heading to bed, the cub rubbed his still aching back, hoping that a few fluffy pillows would ease his pain for a bit, though he was still anxious about the impending birth, still not realizing the gravity of his gravidity. He pulled off his t shirt, preferring to sleep just in his undies, the babies warming his torso sufficiently at this stage. Laying on his side, the babies continued to squirm and shift about as much as they could, the girl still pressing down on his pelvis and bladder, making him so uncomfortable, but he smiled as he rubbed his hands in circles over his tremendous bump to soothe his little ones to sleep, since it seemed to work well at this stage of being so huge and so connected to the twins. After a bit of shifting around to make the pillows mold against his back and legs, Shuuya slowly drifted to sleep as the twins began to slumber as well.
It was the middle of the night before the cub was awakened by his twins flailing within, knocking him out of a dream that he was finally holding them. As he placed a hand at the top of his belly, he realized he had to pee really bad.  Shifting as best he could to sit up, he gasped as the girl pushed down, his bladder uncontrollably leaking as he whined a bit. 
“Not again…why’d you make mommy pee herself, little princess? At least your brother just bruises my ribs, but you make me have to change my clothes and sheets on a weekly basis.  Well, I needed to change these sheets soon anyway,”
After finishing the arduous task of changing the bed at 9and a half months pregnant, the gravid cub sighed at his handiwork, grimacing as his back spasm returned again with a vengeance. He had taken off his soaked batman underwear, finishing his task in the nude as he blushed, seeing his rounded pregnant form in the door mirror. 
“Well, we can’t sleep nude, you two. What to wear, what to wear?” He murmured as he pulled out a nightgown Han had suggested for wearing if he wanted to stay covered, but feel more free. He pulled it over his head, smoothing it over his belly as he giggled, feeling girly, but still like a child with new clothes. As he posed in the mirror, his belly tightened with the first real contraction that he felt in his womb, causing a release of pressure in his pelvis as his baby girl shifted upwards, fluid dripping from within him. The cub squeaked with surprise and then his heart pounded as he realized he was really in labor. 
“Well, you’re finally ready to come out, huh? Mommy thought you’d stay in there forever,” Shuuya said, placing his hands under his belly, cradling his heaviness and his babies before they were born.
