Or one more in the hole.

“Franny are you alright?!?” You both exclaim.

Franny holds up a finger, pats her protruding belly and burps. “I’ve never fucked a guy in the ass before,” she comments, covered in your anal slime.

“I’m glad you aren’t hurt, and I didn’t mind it, but I didn’t realize I would swallow you up so easily,” you apologize.

“So preggers again, huh?” Franny squeezes your new wombs.

“Looks like it, they are sagging past my knees,” you observe. “That’s my sister, though, you play with the hose and you just might get knocked up. I shouldn’t complain.”

“I really didn’t mean to, bro. I could have birthed them much more easily,” Kary apologizes again.

“Sis it’s fine, we get two more to keep in the family. We will figure it out,” you say without conviction.

“You are going to birth your first one easily, if my anal adventure was any indication!” Franny laughs as her belly jiggles along with her chest and balls. Her cock hops merrily.

Wait, what?

“Franny...do you have a penis? I don’t recall seeing one earlier...”

Franny looks down to where you gesture. The lengthening shaft pulses steadily as you watch. “I do now! Oh boy...” Franny can even see it sticking out beyond her belly.

“Bro, remember how you...blossomed...when we first started? Franny is a female...so...she is blossoming in her own way.”

“Well a warning: ‘May cause cocks to grow’ would have been fair, but can’t stop it now, if your ‘blossoming’ is any indication,” Franny thinks aloud.

“Well you still cause my cock to grow, Franny. Another big one to play with is welcome.” You poke her tip.

Her belly is being reduced further as her length gains girth. You stare in wonder as another big dicked beauty is born in real-time. Her feminine features don’t advance at all.

“Is this really all going to my dick,” she asks in wonderment as she gets wobbly with the weight hanging from her crotch. “I thought breasts were bad, but uggh,” she strains and widens her stance and squats until the tip rests on the ground.

“That’s a big one,” Kary muses, while eyeing her still comparitively massive dick.

“Will Franny be...uhm...fertile?” You ask.

“Oh yes, definately! Her normal girl parts are still fully functional, too! Getting any ideas, bro?” Kary breathes. “I can help her put babies in you, if you want...”

“I have three now! I think I’m full,” you remind her.

“She said ‘any orifice’. Is that mouth too?” Franny wonders while patting her still swollen middle.

“Not that, silly! How would you two eat my cum then? The acids kill the swimmies,” Kary explains.

“How about boobies? They are orifices and have ducts and are plenty soft and round and flexible?”

“Right, Franny! Should we knock up my brother’s breasts together? I can give him the juice, and you can just add your DNA!”

“I’ve never came before, but imagine two cums, two pregnancies! I’m in,” Franny claps.

“You know I’m like right here, ladies,” you begin, to quash that idea.

“Right, let’s start.” Kary uncerimoniously pulls your nipple downward and thrusts it into her cockhole while Franny gets in line behind her. “What?” Kary exclaims as your new gal pal grips your sister’s thick hips.

“Ever had your ass knocked up, sister?” You can barely hear Franny whisper.

“Oh gosh, bro, she’s pushing at my rear! I’m sorry!” Kary explodes into your left breast, doubling your size within a minute. The heavy semen mixes up with your milk and the breast sags heavily to the side, as Kary is spent quickly. “Franny, I can’t! It’s too big!”

“Shut up and swap tits,” Franny orders and you both obey. “You can do this, Kary. Knock up those big boobies!” Franny exclaims as you see her fingers dig into Kary’s sides.

“Oh bro, I knocked up one by accident, but-“

“-a matching pair? Of course, sis. I’m all yours,” you say proudly to the mother of your offspring.

“Here we go, aaahhh!”

Franny splits Kary open and you can feel the impact as Kary grabs your breast flesh and tugs hard, extracting milk into her dick. With a defeated look, it comes right back to you as Kary fills your other breast just as hard. She is spent quickly and pushes back at you so she doesn’t add to your breasts that each are the size of your belly plus some and hang to either side of it.

The suspenders snap.

“Told you so,” Kary smiles, exausted, with Franny bouncing off her butt excitedly.
