It's the first day of college and you walk into your new dorm room. However, instead of the new roommate you expected, there's a gaggle of young mice girls! They are all extremely cute, and none of them are older than eight years old. As you walk into the room, one of them giggles and locks the door behind you. Another, sitting on your bed, lifts her skirt to show you her large furry sheath and big, heavy balls. The musk pouring from her body is intoxicating. Another mousegirl pulls open her shirt to reveal large and plump breasts, bigger than any girl her age should have. All of them act in unison, as if their bodies were all part of the same hivemind. As they undress, you see they all have large sheaths and balls, big breasts, and suspiciously fertile bodies. One mousegirl giggles at your staring, showing you her butt... her buttcheeks slowly plumping and growing larger. You can hear a wet squelching noise coming from her tailhole. She turns around, her face red, her breathing labored, and a huge, throbbing, cock and balls dangling between her legs.
"Welcome to our nest, big sister!" she squeaks. "We're going to be living together from now on."
All of them start walking towards you, their breasts swaying back and forth, their cocks flopping, their balls slapping. You can't move. The smell is overwhelming, and you feel your body begin to react to it. You feel your pants tighten and bulge as your own cock begins to swell and pulse. The first mousegirl walks up to you and puts her paw on your stomach.
"I'm the leader," she says, "so I get to do the breeding. If you want to breed any of the others, you'll have to do so through me."
She starts to rub your bulge, feeling its shape with her small paw. She purrs in delight, and starts to strip off your clothes. One of the other mousegirls comes over and starts to help her out. Before long, all your clothes are gone. Your cock, already large, has grown to its full size: a thick, long shaft, with two large balls at the base. The first mousegirl giggles in delight and starts to sniff it. Her breathing becomes labored and heavy, and she starts to lick the head, running her tongue across it. Her erection swells from her sheath and presses between your thighs. She looks up at you with large, hungry eyes.
"I'm going to fuck you now," she whispers. "I'm going to fill you with my seed and impregnate you."
She pushes you to the ground. You're helpless against her strength. You feel her press her cock against your ass, and slowly slide it in. She moans softly as your ass tightens around her shaft, and starts to slowly pump her hips back and forth, fucking you with her thick, long shaft. Her breasts bounce up and down around your cock. Your ass feels so full, and her cock reaches so deep inside you. Her balls slap against your skin with each thrust, sending pleasure up your spine. The other mousegirls gather around, stroking their own shafts and watching you two fuck. You feel your orgasm growing. You're about to cum.
You cum, your body spasming. You shoot your load all over the first mousegirl's breasts. She moans in delight, feeling your seed spill onto her soft, furry skin. She picks up her pace, slamming into you with more force, more ferocity. Her cock throbs and pulses. You feel her balls twitching. You know what's coming. She lets out a squeak and her cock erupts, filling your ass with her hot, sticky seed. You feel her orgasm for several minutes, shooting several large loads of her cum into you. She slows her pace, but her cock doesn't go soft. She keeps thrusting, filling your ass with her seed and her shaft. She doesn't stop until you're filled completely. You can feel her semen dripping from your ass. When she finally stops, she pulls out, letting a stream of semen drip from your ass onto the floor.
She sits down on the bed next to you, panting heavily. She looks at you, a satisfied expression on her face.
"I can see you like my nestmates," she says, grinning. "You're going to be a good breeder."
The other mousegirls come up to you, eager to fuck you. Their cocks are erect and throbbing. They start to strip off your clothes, exposing your soft, supple skin. One of them grabs your arm and presses it against her breasts. Another one starts to play with your nipples. A third lifts your leg and starts to tease your hole with her finger, rubbing it gently. You moan in pleasure, and let them continue. One of them climbs onto your chest and starts to ride you. Her cock is huge and throbbing, and it fills your mouth easily. She pushes it deep into your throat, letting it stretch your lips around its thick girth. She starts to thrust her hips, fucking your throat. She moans in pleasure and her breasts bounce up and down with each thrust. The other mousegirls start to tease your body with their paws, rubbing your cock and balls. It's too much for you. You orgasm, shooting your load all over yourself. The mousegirl riding your cock starts to climax as well, filling your mouth with her seed.
After all of them have cum, the leader mousegirl stands up, stretching. Oddly, it is her belly and not yours that looks plump and pregnant.
"It's time for us to get ready for class," she says. "Let's get dressed."
All the mousegirls start to put their clothes back on. You watch them, still stunned from the sex. Once they're done, the leader mousegirl comes up to you.
"You can stay here and rest," she says. "We'll be back after class."

Six mousegirls leave your dorm room and head into the elevator. Another student is already in there, shocked at the sight of six young mice, who are each sporting deep cleavage, huge bulges under their skirts, and plump bellies. The leader mousegirl smiles at him and presses the button for the ground floor. The elevator doors close, and the student is trapped in an enclosed space with six young mousegirls whose musk fills the air and makes his pants tighten. He tries to ignore them, but he can't help but stare at their bodies. They giggle at his attention, and their cocks start to grow under their skirts. His own cock responds, and his breathing becomes heavy. One of the mousegirls notices and grins, putting her paw on his thigh. Another mousegirl comes up behind him and hugs him, her breasts pressing into his back.
"Don't worry, we'll take care of you," she whispers into his ear.
He doesn't resist as she pulls down his pants. His cock springs free, hard and throbbing. She kneels in front of him and starts to lick it. Her tongue feels amazing on his cock, and he groans in pleasure. The other mousegirls gather around to watch, their own cocks starting to grow and strain against their skirts. The one licking his cock takes it into her mouth, sucking and licking it. She pushes it deep into her throat, taking it all the way to the base. The other mousegirls start to undress, their breasts bouncing free and their cocks growing erect. They all start to masturbate, stroking their cocks and playing with their breasts. The elevator reaches the ground floor, and the doors open. The mousegirls don't stop. They keep masturbating, letting everyone see their bodies and smell their musk. They keep masturbating as the other students walk past, some of them staring in shock, some of them with bulges growing in their pants. They keep masturbating until they cum, shooting their seed onto the elevator floor.
They're not finished with him yet. They drag him out of the elevator and into the lobby, where more students are milling about. They force him to his knees and surround him, their cocks pointing at his face. The leader mousegirl takes charge, and starts to stroke his cock. The other mousegirls follow suit, stroking their own cocks in unison. He can't help but moan in pleasure as he feels their paws on his cock, stroking and squeezing it. He can't help but look at their cocks, each one bigger than his and throbbing with need. They keep masturbating, their balls twitching and their cocks pulsing. The musk coming from their bodies is overwhelming, and he can't help but feel his own cock throbbing in response.
Suddenly, the mousegirls let out a squeak of excitement. They've cum, shooting their seed all over his face. He feels their warm, sticky seed cover him, and he can't help but climax as well, shooting his own load onto the floor. The mousegirls giggle in delight and start to rub their semen into his skin, making him smell like them.
"This is our territory now," the leader mousegirl says. "We're going to use your body to breed our nest.
