It had been a crazy idea but certainly not the worst they'd come up with. Leaning back in his chair, Sebastian watched his sister pacing around the bedroom of their small apartment as her hefty pregnant belly swayed teasingly with every step. The twin rabbits had been waiting for Stella to go into labor when she'd proposed the idea to him.

"I mean it's basically just recycling," she commented as she continued to pace, not looking at her brother or the sizable arousal between his legs. "It's healthy, right?"

"Seems like it," Sebastian said as he casually stroked his cock and focused his attention on his sister's naked breasts. "It's like mom and dad always told us… they made us so they could unmake us. Besides, with how much we fuck there'll be plenty more." Leaning forward, he gently took his twin's hand and said, "Do you want this?"

Stella looked down at him and nodded. "Hell yes. Let's do it."

Grinning wide, Sebastian stood and said, "Let's do it in the shower so when your water breaks it'll be easier to clean." Hooking an arm around her waist, he then escorted her to the bathroom. 

Shivering in his arms, Stella put a hand to her swollen stomach as she said, "It knows something is happening. It's kicking like crazy."

That grin never faltered as Sebastian went about turning on the shower and adjusting the water. "Well, it can just be patient. Did we ever find out the gender?" 

Stella shook her head. "You kidding? I didn't want anyone to know you knocked me up. Hell, it's a miracle no one knows yet. If we didn't both work from home and get most of our shit delivered… No beach time this summer sucked but I couldn't risk running into anyone we knew."

"Which is a shame cause you look absolutely hot as hell pregnant." Sebastian leaned in and kissed her. "I kind of want to keep you this way. Breeder looks good on you."

"Mmmf?" Stella kissed her brother deeply. "Mmmm well then I guess I'll be sure to throw out any birth control in the house… so long as you're willing to do this every time until we decide to keep some."

Helping his sister into the shower, Sebastian gripped her ass firmly as he assured her, "Gladly. Now… bend over."

"So forceful," Stella said with a laugh as she leaned forward and gripped the shower bar they'd installed for this exact purpose. Offering up her backside, she wiggled her hips and said, "Come break my water Daddy."

Smirking, Sebastian stepped in behind his sibling and said, "Sure thing Mommy. Let's unmake a baby." Pressing the head of his cock between her lips, he thrust into her firmly. He loved the sounds of his sister's moans whenever he rough rode her and now, sensitive as she was with her impending delivery, her body reacted all the more eagerly. Her walls gripped him as he forced his entire length into her in one rough motion. 

Stella whimpered as she felt her body tense up hard. With a gasp, she felt a shifting in her swollen stomach before a rush of warm fluid poured from her depths and soaked her brother in the process. "Damn… fuck Seb, you broke my water in the first thrust."

Sebastian snorted. "I mean it's how I broke your hymen our first time. It's fitting. Now, breathe and push… get that baby out of you. Your womb needs to be empty so I can fill it back up."

As she nodded her head, Stella felt the first contractions starting to slam into her. Each time her brother slammed his hips forward and drove his cock deep against her core another spasming of her internal muscles helped move the process along just that bit more. Finally, she threw her head back with a pained cry as she felt her cervix spreading around their child. 

Continuing to thrust into his sister as he felt her muscles grip and spasm in her birthing contractions, Sebastian chuckled when she gave the signaling cry that their child was descending. Leaning over her, he doubled up his efforts as he continued to buck into her hard and fast. "That's it… breathe breathe push just like the videos said. That's a good breeder bunny… give me that baby."

After several more minutes of thrusting and cries from Stella as her vaginal canal stretched around their child, Sebastian started to feel the change in pressure around his cock. After a few seconds, he felt something press down against the tip of his cock as he finally came to a stop in his rutting. 

Petting his sister's ass, he said, "There it is… there's our little one. You feel that sis? Our baby is right up against my cock. Keep pushing. Let's get rid of that unwanted burden shall we? Let's unmake it."

Stella panted heavily, her entire body shaking from the effort. Gripping the bar with as much strength as she could muster, she whined and continued to push. 

Sebastian closed his eyes as the pressure against his cock mounted higher. Biting his lip, he felt the head of their unborn child press firmly against him with each push his sister gave. With a gasp of delight, he finally felt it happen. That pressure changed as the opening of his cock spread and their child's head slipped inside of him. 

Moaning out, it was all Sebastian could do not to climax then and there as their child slowly descended down into his cock inch by inch. That sweet baby bunny, not even truly born yet, was already head deep inside of his cock. As its shoulders reached him, Stella timed her pushes to help work their child in deeper. 

Of course, that still meant her own body had to stretch too. Crying out, Stella felt their unborn child crown past her labia lips from within her brother's cock. She tensed and whimpered in exertion as she took in sharp breaths to steady herself. Then, with as big a push as she could manage, she felt their child slip quickly through her body. 

Sebastian cried out from the rush as their child skipped fully into his cock, the tip closing behind the infant's toes. That final push forced the child through his shaft quickly and down into his heavily distended sack. He could feel the weight his sister had been carrying for so long now settling into his left testicle. Slumping forward, his head spun as the rush of hormones and euphoria swept through him in the heated haze of the shower. 

After several minutes of recovery, Sebastian finally pulled out and leaned against the wall for support. Looking down, he almost laughed at how comical his engorged sac looked between his legs. Already, he could feel the gurgling and churning of his balls as they worked to digest the squirming, kicking child inside of them. 

"Mmm, that's right kiddo. Back to cum for you. If you're good though I'll knock mommy back up and give you a second chance."

Stella shuddered as she looked back over her shoulder. "Promise?"

Sebastian nodded. "Promise. Maybe this time it'll even be twins. We might keep them if they're twins."

"And if not?" 

Smirking, Sebastian licked his lips. "Then we just unmake it and try again." Deep in his nuts, the kicking finally stopped as his cock twitched impatiently for It's chance to start this cycle over again just like they had done so many times before.
