Wake up

You blink sleepily as the morning sun shines through the large window. You're still not used to waking up as a female, let alone as one without legs. You stretch your arms, yawn, and gaze around the room. Suddenly, you notice someone in the kitchen and jump in surprise.

It's another monster girl like you, only this time, she's a naga. She has the lower body of a snake, with scaly ears to match. Her scales are red, as is her long, stringy hair. [Miia, Monster Musume]

She's wearing clothing too. A large, red t-shirt covers her breasts and vagina. For the first time in a week, you feel a bit of shame. You instinctively cover your nipples and pussy with your arm and hand.

The naga digs around in the fridge, searching for leftover food, not paying any attention to you at all. She pulls out a slice of cold pizza, jams it in her mouth, and slams the door. Then, she scratches her butt and slithers over to the living room. As she passes by the tank, she glances at you for a second. Then, the next thing you know, she does a double take, jumps backwards about a foot, lets out a short yelp and drops her pizza face-down on the floor.

"Fuck!" She exclaims. "I uh.. Oh.. Um... Well, hi there! When the hell did you arrive?"

You immediately grab two pillows and use them to cover yourself.

"Last... Night?" You respond meekly.

"Goddamn, really? How late? Papi and I were up until two in the morning..."

"How should I know?"

"Fair point." The Naga recovers and picks her pizza up off the floor. She takes a bite of it and slithers over to your tank, not bothering to clean up the red stain on the carpet. You clutch the pillow tightly.

"Hey now..." The naga responds. "I don't bite. I'm not like the other nagas from Alex's hell hole. I ain't aggressive."

"Other... Nagas?" You ask.

"Never encountered them, huh? Be thankful... They're a bit on the... Predatory side. In both ways..."

You shiver.

"Anyways, welcome to the monster house. Well, that's what I like to call it anyways. It's more of a monster tower. You're Mero, right? My name's Miia. Hope you enjoy your stay."

"How'd you know my name?"

"Oh, right... Our uh... 'owner', Mr. Takeshi, er... SHIROU Takeshi, is a big fan of this Manga with a bunch of monster girls in it. Monster Musume, it's called...

Anyways, he used a big chunk of his money to bring his fetish to life. We basically live here. We perform sexual acts for him, and he gets us pretty much anything we need."

"I'm sorry, you do WHAT for him? Willingly? And you don't ever try to escape?"

Miia blushes and guiltily averts her eyes.

"Right... About that... We've kinda all given up on trying to escape after like the first month or so..."

"Huh?!"

"Well, it's really quite nice here... We don't have to work, we get whatever we want, and Mr. Takeshi is actually really nice and caring. Sure, we're his pets technically, but that doesn't stop him from treating us well and spending time with us...

Besides, we couldn't leave even if we tried. The shock chip would activate if we left the building or moved 100 yards away from him..."

"S-shock?!"

"You'll get yours in about a week or so. It's really nice. Then you're allowed to go throughout the tower and do all kinds of fun stuff."

"Oh yeah, sounds like a TON of fun. And what about the... you know?"

Miia goes kinda quiet, and sheepishly looked away.

"This is gonna sound nuts, but... The first time he pulled out his dick... I couldn't help myself. I still can't... I've gotten used to it, but I think it was something Alex did. I used to be into girls, but... I think she messes with our brains."

You stare at Miia suspiciously.

"Anyways, besides a few things, Shirou really isn't a bad guy, you'll see. Hey, you want anything to eat, by the way? I'm not sure... what... your kind eats? (Is, is that racist for me to say that?)"

You shake your head. Miia shrugs.

"Well, okay then. I'm just gonna be watching TV. Shirou should be here in about an hour."

Miia slithers off and picks up the remote. She plops her butt down on the couch, and switches the channel to American television. Five minutes later, a blue feathered, blue haired harpy sleepily shuffles from the hallway to the right. She gives you a sleepy wave, pours herself a bowl of cereal, and sits down on the couch next to Miia. [Papi, Monster Musume]

You swim around your tank a bit, but eventually you get bored. You lean your arms on the side of the tank wall and watch TV over Miia's shoulder.

An hour later, the door opens, and in walks the man himself. He's average height, has black hair, and is decently built. He looks nothing like you expected. He's fairly young, clearly in his twenties. He's not even wearing a suit, but a laid-back t-shirt and jeans. You shoot him a nasty glare, but to your surprise, he's so friendly and cheerful that you're the one looking bad in the process. You were expecting a fat, ugly, old, egotistic businessman. Not some casual college student.

Shirou walks into the room, carrying a shopping bag. He smiles and sets the bag down on the table and waves to Miia and the Harpy. They wave back.

"Good morning, Miia! Papi! How are you today?"

"Meh. Tired." Miia responds.

"Same." Papi replies.

Shirou chuckles and carefully steps over the pizza stain on the ground. He walks over to your tank and waves hello. You can't reasonably stay mad at him. You try, though.

"...And you must be Mero!" He states. "Mrs. Ayako told me you had arrived. Pleased to meet you!"

"Fuck off." You responded rather rudely. Shirou just takes it though and shrugs.

"Gotta expect that from a new arrival... I don't blame you, to be honest. Trust me, it's not so bad here... You'll see..."

Shirou takes notice of your nudity. You immediately blush, freak out, swim as far back as you can, and cover yourself with your hands.

"I've got your clothes right here in my bag... But first, we should try you out."

He turns to Papi and Miia.

"You guys mind giving us some privacy?" He asks politely. Miia and Papi sigh, and move of to their rooms. "Fantastic. Now... You know what to do."

He fiddles with a controller on the tank side, and suddenly, the tank starts to lower down to his crotch height. You start to let him know what exactly you think of this entire situation.

"If you think I'm sucking your dick you've got ano-"

"Ziiiiip"

Shirou pulls out his large, floppy cock, and droops it on the tank wall. It seems to stare at you, inviting you to come and see it. You immediately shut up, and stare at it. Something about it seems so... so wonderful. You felt a tingling in your pelvic region.

"It's so... Big." You murmur in surprise. You blink, and swim a bit closer.

"Why... Why does it look..." You trail off. You lower your arms, exposing your privates. You swim right up to it. Slowly, you raise your hand and poke it. It feels soft and warm. It was a familiar feeling, but never before had you been so enticed by it.

"Maybe... Maybe just a little stroke..."

You wrap your hand around the sausage, and begin to stroke it. Before you know it, it's rock solid, and your heart is practically beating out of your chest. Without noticing, you gently rub your clit.

"Okay..." You sheepishly stammer. "Just... Just this once..."

You close your eyes, open your mouth and stick out your tongue. You lick the head of Shirou's dick. It's warm, soft and spongy. You love it. You stick the dick in further and close your puffy lips around it.

"Mmmmmm..." You moan. It was hot, shrively and gross, but you LOVED it. Something about it, just made you want to FUCK. Or rather, it made you want to BE fucked!

"Is this... Is this what it means to be a straight girl?" You think to yourself.

You bob your head back and forth, going deeper and deeper until his head pounded against the back of your throat. You glistened his shaft with your saliva, and carefully caressed the ridge of his penis head with your tongue, lapping up the wonderful, salty pre-cum along the way.

Finally, he cums. You can feel the semen explode inside your mouth, it's salty, sticky substance providing a strangely enjoyable flavor. He pulls his sopping wet dick from your mouth, forming a stringy bridge of seed between the tip of his cock and your slutty lips. You swallow his cum, let out a sigh of satisfaction and let out a girlish giggle.

"Have some more, big boy..." You say sexily, and flip your tail up onto the tank wall, exposing your vagina to him. He just laughs, wipes off his dick, and zips his pants back up.

"I think that's good for now... Let's wait until you get your wheelchair before we go any further..."

...

Three months later, you're sitting in your tank, wearing your bikini Shirou got you. It was a lacy, maid-like swimsuit, made specifically for you. You also received a less revealing outfit for when you were out in public.

You pull yourself out of your tank and hop in your wheelchair. Another thing that Shirou had gotten you. It allowed you to move around outside of water, but only for a few hours. He'd also gotten you a personal, waterproof TV, and a better, more comfortable bed to sleep on.

You wheeled up to Miia and Papi who were watching TV, and grabbed a handful of Miia's popcorn. You thought about Alex's tantrum on the day you were reborn. Maybe she was angry because your sexual orientation didn't turn her on anymore. Either way, you didn't care. You loved getting fucked by Shirou. You'd done it every other night, and had no regrets. You had truly become a straight-up woman.
