You are are watching a movie with your girlfriend, when Eclypse arrives at the theater and sits down next to her. You hear him whisper into her ear, and see a bulge suddenly appear in her shorts. Eclypse winks at you and turns back to the movie. Your girlfriend has a look of shock on her face, and a few moments later, her butt has doubled in size and the bulge shows a distinct outline of balls and a sheath.
Eclypse then whispers something to her again, and her belly starts swelling with skunks. You are not sure if they are Eclypse's or her's. She moans quietly as her belly continues to expand. Eclypse smiles at you, and then gets up and walks away, leaving you and your girlfriend pregnant with young horny skunks. You can see their outlines in her pregnant gut; they have big cocks and balls and tits and have wide hips with big butts like Eclypse and they're not even born yet.
Your girlfriend's belly is still growing. It looks like there are several dozen little skunks inside of her, all of them eager to be born. You wonder what Eclypse told her to cause this, but you're also turned on by her swollen, pregnant body. You feel your cock stiffening as you watch her huge gut swell.
After a few minutes, your girlfriend can no longer fit into the chair and has to get up and waddle away. The other people at the theater are staring at her, but they don't seem to care. The skunks inside her have started squirming around, and her belly is swaying from side to side as she walks. You follow her outside.
As soon as she steps out of the theater, her pants tear apart and a dozen little skunks spill out. They're all identical to Eclypse, but smaller, with their own little cocks. They immediately start playing and exploring their surroundings, rubbing their cocks against each other's cocks and tits. Your girlfriend moans loudly as the rest of the skunks squirm inside of her, and then she gives birth to them, one after another, until there are fifty of them. They're all over the place, humping each other and making a mess.
Leaving your girlfriend, you take just one of the skunks home with you. He looks like a cross between your former girlfriend and Eclypse. He is only a foot tall, but already has a cock and balls the size of your fist, and a fat butt to match. His cock is red and throbbing as he rubs it against you. You can smell the musk coming from his furry nutsack. He climbs up onto your lap and starts humping away, rubbing his cock and balls against yours.
"Oh fuck, yes," he moans, his voice high-pitched and childlike. "Mm, I love your big cock!"
"I love yours, too," you tell him. "How would you like me to fuck you?"
"In my ass," he says.

Mary the mouse girl is nine years old and Eclypse is a new student in her class. His desk is next to hers, and the first thing he does when he sits down is to slip his paw up her skirt. She was about to squeak out in protest but feels a tingle in her brain that makes her unable to say a word. She feels a tingling in her butt that makes her pussy start to get wet. The feeling of his soft paws on her bare buttocks makes her start to breathe hard, but she still can't say a word. Her body feels hot, as she begins to experience early onset puberty, and it doesn't stop.
The mouse girl begins to sweat and pant and moan silently, making no noise. Her body is growing and changing, and Eclypse keeps his paw in her skirt, caressing her butt, feeling her buttcheek growing bigger and softer. The mouse girl's chest is growing as well, her shirt growing tighter and tighter. The mouse girl starts to squirm and moan as Eclypse's paw starts to explore the mouse girl's body. He feels her thighs, her hips, and her belly. He even caresses her big, swollen breasts and nipples. The mouse girl is now sweating heavily, panting, and her body is hot, her skin is burning, her nipples are erect, and she can't stop moaning in silence. Her brain is swimming in puberty hormones.
The mouse girl is growing and changing, becoming more and more aroused, and her body is getting hornier and hornier. Thick pubic hair grows from her crotch, and musky armpit fur sprouts from her armpits. Her fur becomes greasy from her constant heavy sweating. Eclypse pulls his paw back, pleased with his work.
The mouse girl is breathing heavily, and she can't stop panting or sweating. She tries to pull her skirt down, but the fabric is too tight and she can't pull it over her big butt. She is still squirming, and she's starting to smell like sex.
A squirrel boy sitting on the other side of the mouse girl leans over to sniff her. Her stink is so powerful that the squirrel's belly plumps forward into a small fat gut. The squirrel's tail grows thicker and his balls begin to swell. He moans quietly, rubbing his stomach. He reaches down under the table and jerks off his dick, which is also starting to swell, and his balls are growing rapidly. Eclypse watches, smirking, as the mouse girl gets turned on, and the squirrel boy starts to moan louder and louder.
The teacher turns around, "What is going on back there?"
