And finally we're back to this series ^_^

I was amazed at Mia's thirst. After making so much cum, I figured I'd be the one sucking down most of Mommy's milk, but no. I finished with my meal, my cock sliding out of my tunnel again now that my energy had returned, yet Mia kept going. She moved a bit and pulled both of Mommy's nipples to her muzzle, slurping eagerly at the creamy liquid like she hadn't eaten in days. It was really cute the way she mrrred between gulps, her tail twisting about lazily in utter contentment.

Seeing my cock back to full strength, Mommy smiled at me before petting Mia's head softly. "You can keep drinking all you like, Mia, but this is just part of the fun. Do you want to know why my and Fina's tummies are so big?" Mia looked up at Mommy, nodding vigorously without stopping her feeding. "It's because we're pregnant. You're going to have lots of little siblings running around after a while." Mia's eyes went wide, and Mommy's grunt of pleasure told me she had started to suck harder. "I see you're happy about that. Wanna know who the father is?" When my little sister nodded again, Mommy pulled Mia away from her feeding and turned her to look at me, laying the little vixen's head between her boobies..

Mia's mouth hung open in shock. "You mean Fina...?" "That's right, honey. Fina made Mommy pregnant. You see that big hard thing under her tummy? Usually only boys have those." She reached down around Mia's now slightly milk-rounded stomach and rubbed her fingers along her wet privates. "When a girl lets a boy put that hard thing into here, they squirt some of that white stuff we've got on our fur really deep inside and it can make the girl pregnant. Daddy did that to me and it made you and your sisters in my tummy." Mia had started to squirm from Mommy's fingers and her heat, the sight of my cock fascinating to her. "Fina's is special. Usually a cock grows to the same size, but hers grows to fit the girl. I think it's made just for you this time. Do you want to try it?"

Mia squirmed harder despite herself, hesitant as before. "D-does...does that mean Fina wants to get me pregnant?" Mommy nodded towards me. "Why don't you ask her?" "But...it's embarrassing..." Mommy laughed. "Don't worry honey. She liked getting me pregnant a lot. Almost as much as I did." Mia looked back at me, unsure of herself until she got the same determined look on her face as before. "Fina, would you like to make me pregnant?"

I just about came all over both of them right there! It was one thing to have Mommy say it, or have Mia ask Mommy about it, but for her to look up at me with that cute little face and big, needy brown eyes and ask directly if I wanted to give her a big, round, kit-filled tummy got me so excited! My cock began to leak pre at an alarming rate, the puddle on the floor soon touching my footpaws. "Of course I do, Mia. Why wouldn't I want to make you pregnant with my babies?"

Mia licked her muzzle again, seemingly still thirsty. "Mommy? Does it hurt when she puts it in?" Mommy rubbed her ear a little. "If it's your first time, but it's only for a little bit. If the one mating you knows what they're doing, the pain goes away almost before you have a chance to complain. I don't know how, but believe me when I say your sister knows what she's doing." I blushed at the compliment, very happy that my Mommy had felt even better than I did when I filled her with my sperm. "Thank you, Mommy."

Thanks to Mommy's teasing, Mia's privates were leaking almost as much as my cock. The smell of her heat was driving me wild, but I knew I had to wait. I wanted to make her happy like I had Mommy, not scare her. She wasn't done with her questions yet. "Will I get big right away?" Mommy nodded. "Normally it'd take a while, but you saw how much sperm Fina makes. I'm so big because Fina filled me so full. I have lots of babies in me, but they're still really small. It'll take a while for them to grow big enough to birth." Mia looked at me for a bit, then at Mommy, rubbing the bulge she was resting against. "Did...did it feel good to have your tummy get big like that?" Mommy grinned and mrrred happily. "I loved it. I can't wait for her to do it to me again."

Through my excitement, I could see Mommy's boobies getting full again. I couldn't believe how fast Mommy was making milk! They were getting bigger before my eyes, swelling gently with more of that delicious white cream. Her nipples leaked constantly, a lot of it dripping onto her swollen tummy and Mia's shoulders. The image of my cock pushing in to those swollen teats jumped into my head, making me gasp. My cock throbbed excitedly, but it would have to wait until Mia was satisfied.

"Mommy, will getting pregnant make my boobies grow? I want ones like yours. They're so pretty." Mia squeezed one of Mommy's boobies, making milk squirt out and hit my pregnant tummy. She licked her paw clean, her thirst starting to get the better of her. Mommy mrrred again from the stimulation. "Yes, they will, sweetheart. Look at Fina's. She just got pregnant last night, and they're already bigger. They'll just keep growing until they fill with milk like mine."

It seemed Mia was almost out of questions, her arousal and thirst nearly urging her forward."What about Jenny and Daddy?" Mommy rolled her eyes and turned Mia around to face her. "Silly girl. Once they get home, we'll all play together. I bet Jenny would be really jealous if you got pregnant before her. I'm sure Daddy will be happy to mate with you too."

"I..." Mia looked back and forth between Mommy's leaking boobies and her face, licking her muzzle frantically. "I want..." She roughly grabbed Mommy's boobies and stuffed the nipples back in her mouth, taking several long pulls and gulping down the much larger volume of milk. She broke away just long enough to turn to me, her eyes filled with need as she got to her knees, raised her hips, and lifted her tail, presenting her dripping privates to me. "I need you to get me pregnant!"

Again, I just about came right there. I moved up behind her, the need to tease her winning out barely over the lust. I took Mommy's paw and had her rub my cock up and down her privates, mixing our juices together. "You want me to push into you? Should I take your virginity? Do you need me to put my semen in you so that you'll have my babies? Would you like me to fill you so much that you swell up like me and Mommy?" Mia yipped in frustration, trying to push back to me to get the tip in as she gulped down more milk. "YES! Please! Give me your babies so my boobies get big! It hurts not having you in me!"

Now that I was absolutely sure she wanted it, I pushed forward. Mia hissed in both pleasure and pain, my cock stretching her wide for the first time. I wrapped my paws around her hips, my massive belly pushing her tail up along her back. "Argh....Mia, you're so tight!" "Be gentle on her, Fina. I've had lots of practice, so you'll have to go slower this time." I nodded, gritting my teeth in an attempt to restrain my impulse to shove as hard as I could. Mia rocked back and forth as I did, pushing back and pulling away at the same time I did. Little by little my cock split her open, our combined juices helping to ease the way. The vice grip on my cock was just shy of painful by the time I finally reached her hymen.

She squeaked when I bumped into it, her paws squeezing Mommy's boobies again and again to shower her with milk. "Mommy, she hit something in me." "That's your virginity, sweetie. She's gotta break that to push in and give you babies." Mommy was clearly enjoying the show, her tail pushing in and out of her privates. "Doing it quickly is best. I want you both to pull back and push in a few times until you can do it easier, then push in hard. I promise it'll get you past it easiest." We both nodded. "Ok, Mommy."

It didn't take long to get a rhythm going. It was slow at first, her tightness making movement difficult, but we adjusted soon enough. About a fourth of my cock was in her when I hit her barrier, and just the tip stayed in when we pulled apart. Soon we started going faster, and Mommy gave me a look. I somehow knew instinctively what she was waiting for, so I went along with it. Mia yipped and moaned in growing ecstasy, her eyes fluttering open and closed rapidly. I could feel her spasming around me, the pattern I knew from Mommy's tunnel repeating itself in Mia's.

When she let out a long cry, gripping Mommy's boobies so hard the milk spurted out over my head and across the room, I knew it was time. Mommy grabbed Mia's shoulders and pushed her towards me as I gripped her hips and thrust in. The barrier broke with little resistance, my cock sliding several more inches inside of her. "How does it feel to be a woman, Mia?" My little sister shook, barely able to support herself even with the two of us holding on to her. She sighed and mrrred happily, the pain apparently totally lost in the pleasure. "It...it feels so good, Mommy..." We stopped as Mia collected herself after her first orgasm. I remembered how incredible it was, so I wanted to let her savor it.

When she finally caught her breath and got control of her muscles again, she wiggled her butt against me, sending shivers through my body. "When do I get pregnant?" Mommy pulled Mia's muzzle up to her and gave her a long, sloppy kiss. I watched excitedly, my cock getting a little bigger from the sight, before they pulled away. "Almost ready for that. Fina has to pass one more barrier. Once she's past that, she'll be all the way in your womb where her sperm can do the most good." I could feel Mia's tail trying to move under me in her excitement. "You mean give me lots of babies?" "Right."

Mia went back to drinking from Mommy's boobies when I started to thrust again. She moaned between gulps, and her now somewhat looser tunnel sucked on me vigorously. I really couldn't believe that I'd lasted so long. The show I was being given between Mommy and Mia, the questions that gave me incredibly arousing thoughts, and the potency of Mia's heat all combined with the pleasure her tunnel was providing to get me extra hot. It was almost a relief when I hit her cervix, since I wasn't going to be able to hold on much longer.

"Ah...Mia, I'm just outside your womb. You're making eggs in there right now, so when I push inside and swell you up with my cum we'll make lots of babies." Mia shuddered as I talked, my pre loosening the tight ring. I didn't say anything about my knots, wanting them to be a surprise. Mia drank hard from Mommy, the sensations from her daughter and her tail sending her into a hard orgasm. "Yes, Mia! Drink from Mommy!" Mommy's paws held Mia's head tightly, the flow of milk growing too great for Mia to swallow. Large amounts spilled from those overloaded milk factories, drenching Mommy's tummy in it.

I pushed insistently at Mia's cervix, my own orgasm rapidly approaching. The moment I felt it give, I shoved hard. A gurgled yip escaped Mia's lips through the milk flow, her eyes rolling back again and her tunnel sucking me all the way in. Her second orgasm peaked when our privates met, the tip of my cock pressing into the back of her womb, and it was all over. My knots swelled, locking me into both her tunnel and her womb, and the flow of semen began.

My toes curled in anticipation, my cum seeming to take ages to reach the tip. Like the previous times, it pooled around the first knot, broke through, then pooled around the second knot, before finally racing towards the tip. Both of us screamed in ecstasy when the first thick spurt left the tip, the pleasure so great that I started seeing stars. It felt harder to push out this time, like it was thicker and stickier than before, and I swore I could feel my sperm wriggling in and around my cock as I filled Mia's tiny womb.

From my vantage point, I couldn't see Mia's belly expand. I could feel the pressure growing around my cock, and knew it must be happening. Gallon after hot, impregnating gallon poured into my sister's ripe inner chamber, drenching every nook and cranny in enough sperm to knock up my entire school. Each time a new wave hit me my toes curled again, leaving gouges in the floor as my body injected more sperm into my little sister. I struggled to breathe from the intensity, gasping for air between screams of pure joy.

By the time the flood began to slow, I noticed something odd. Mia seemed to slowly be moving higher! I forced my eyes to focus, looking around my own belly to see that she had swollen up so big her belly was pushing her up off the floor. Her tummy was huge and round, her arms not able to reach all the way around it, each weakening pulse of cum pushing her up a little bit more. It might have been her small size, but she looked to have even more cum in her than Mommy!

Both Mommy and Mia came down with me, all three of us completely out of breath. Through her gasps, I could hear Mia weakly. "I...love...getting...pregnant..." Almost on cue, the vision of what was happening inside Mia's womb hit all three of us, my sperm assaulting her eggs and inseminating all of them a dozen times or more. Mommy and Mia hit one more spasm of ecstasy, both my male and female parts tensing up again. One final thick gush of sperm forced its way into Mia's womb, and it was done.

Mommy helped us roll to the side, my knots keeping me firmly locked inside Mia. I heard my little sister's snores after a few minutes, the entire ordeal exhausting her. Mommy came up behind me and curled up against me as best she could, nuzzling my neck. "I'm so proud of you, honey. You made your sister's first time a wonderful experience for her. Thank you so much." Stuck as I was between two warm and soft bodies, sleep tugged me down despite my best efforts. I only managed a "welcome, Mommy..." before sliding into dreamland...
