Yuto, Suzu, Kenichi, and Miyuki were four university students who had been close friends for quite a while. One day, Yuto and Suzu started dating, while Kenichi had a crush on Miyuki, but she always turned him down. Frustrated with being constantly rejected, one day Kenichi purchased special drugs from the dark net and managed to get everyone to take them without them realizing. Then he proceeded to brainwash them. He got Miyuki to think that she is a dog and act completely like one, with the only difference that she wouldn't mind and enjoy being intimate with humans. He then brainwashed his other two friends to forget that Miyuki ever existed, and, if they were to ever see her again, to just see her as a normal dog. Miyuki now spends her life happily as a dog in Kenichi's apartment, completely naked, wearing nothing but a pair of fake dog ears, a dog collar with a bone-shaped name tag, and a fluffy dog tail buttplug.

Suzu: Can't wait to show Kenichi the present we bought for him, do you think he'll like it?
Yuto: Of course, you always pick the best gifts.
Suzu and Yuto arrive at Kenichi's door and ring the doorbell, after a few moments Kenichi answers the door.
Kenichi: Eh? You guys actually came? I thought that our yearly Christmas party wasn't going to happen this year, with you two now dating. Wouldn't you have preferred to do something just the two of you?
Suzu: Don't be silly! We wouldn't miss spending time with our friend for anything.
Yuto: Yeah, bro. Me and Suzu have plenty of time to go on dates on other days.
Kenichi: Thanks guys, I appreciate it. Before you come in I have to warn you that I did get a dog, she's kinda big, but really friendly. Hope it doesn't bother you.
Yuto: No worries, dude. Dogs are cute.
Suzu: I love dogs! They're so soft and fun to play with!
Yuto: Oh right, we brought you a present too. Suzu picked it herself.
Kenichi: Wow, thanks. Now I feel really bad for not getting you anything.
Suzu: Hey, no problem, you don't have to return the favour.
Yuto: Come on, let's come inside already. It's freezing.
Kenichi lets Suzu and Yuto enter the apartment. As soon as Suzu and Yuto step inside the house they are greeted by a very happy and excited Maya, wagging her butt plug like a real tail and walking towards them.
Suzu: Aww, look how adorable this doggy is!
Suzu bends down to pet Maya, but Maya takes a step back, confused by the situation. Suzu tries once more to pet Maya, but Maya steps away yet again.
Suzu: Is she shy?
Yuto: Maybe. I guess she needs to get used to our smells.
Kenichi: Don't worry, she just needs some time. I'm sure she'll start begging for belly rubs and pats very soon. I didn't prepare anything so I'll do a quick run to the convenience store to get some snacks and drinks. You two are okay staying here with Maya?
Yuto: Yeah, that sounds good, dude.
Suzu: Go ahead.
Kenichi: I'll be back in like 5 minutes.
Kenichi leaves Suzu and Yuto alone with Maya. Maya starts to get more curious and goes up to Yuto and sniffs his feet, while he pets her head. Maya then starts sniffing Suzu's legs and thighs. After sniffing for a bit Maya suddenly starts licking Suzu's inner thighs, then goes for her crotch, making Suzu squeak in surprise.
Suzu: Hey, girl, not there... Down, girl.
Yuto: Oh, looks like she wants to play with your clothes, Suzu.
Suzu: Wait, what? That's not it...
Yuto: Look at how much she's pulling your skirt with her mouth.
Suzu: Well don't just stand there, help me out a bit, she's kinda strong, I can't stop her.
Yuto wraps his arms around Maya, grabbing her chest and pulling her away from Suzu. Maya whimpered a bit, partially because of losing her new play interest, partially because Yuto's hands feel nice on her breasts.
Yuto: There, that should hold her for a little while.
Suzu: Phew, that was close. I didn't expect her to be that interested in my underwear.
Yuto: She probably thinks you smell nice, I know I do.
Suzu: Not funny, babe.
Maya whimpers in disappointment, looking longingly at Suzu's clothes.
Yuto: Don't worry, she's just curious, she doesn't want to hurt you. She's kinda chubby though, especially around the chest, maybe Kenichi is feeding her too much.
Suzu: Maybe it's just the dog breed? Some large dogs are like that. Not really sure what breed she is though.
Maya squirms and struggles to get free, but Yuto holds her tight, not letting her get free. After a few more attempts at breaking free Maya stops, and relaxes, seemingly accepting her current position. Maya can feel Yuto's body warmth and the feeling of being held tight makes her happy, especially when his hands occasionally massage her breasts. Suzu meanwhile is looking at Yuto and Maya and is becoming a little envious of Maya's position.
Suzu: That looks nice.
Yuto: What does?
Suzu: Cuddling with a dog. It looks fun.
Yuto: Do you want to cuddle with her too?
Suzu: (blushing) A little, but maybe when she's calmed down a bit more. I don't want her to start jumping on me again.
Suzu and Yuto both continue playing with Maya for a bit, until they hear Kenichi unlock the door and enter the apartment.
Kenichi: I'm back, got the drinks and the snacks.
Yuto: Sorry, Maya was being a bit too active so I had to calm her down and hold her still.
Kenichi: Did something happen?
Suzu: She tried to play with my clothes a bit too aggressively.
Kenichi: Oh, I'm sorry about that. She doesn't usually do that. I guess she hasn't seen a girl yet so she got a bit too curious.
Kenichi puts his bag full of snacks on the table and starts walking towards Yuto and Maya, as soon as Maya sees him she stops being still and starts squirming to try and break free from Yuto. After a few moments Maya succeeds and quickly runs towards Kenichi and starts jumping around his legs.
Kenichi: Who's a good girl? You are! Yes you are.
Kenichi crouches down and starts petting Maya. Maya then jumps on Kenichi, trying to lick his face. Kenichi laughs a little, amused by Maya's antics.
Yuto: So still no luck getting a nice girlfriend? If you're saying she hasn't seen one before?
Kenichi: No, although, having Maya has helped a lot with not being alone around the house.
Yuto: Oh come on, you can't replace a girlfriend with a dog.
Kenichi: It's not the same, I know, but she's a good girl, she keeps me company. She likes to sleep on my bed and do... Lots of playful things in general. She's more than a handful, haha.
Yuto: (sighing) Yeah, but there's one thing that a girlfriend will do and a dog won't, bro.
Suzu: (smirking) Oh yeah, what's that?
Yuto: (smirks back) You know. Bro You're always studying, when was the last time you had sex?
Kenichi: Ah come on, don't ask me that in front of Suzu.
Suzu: (laughing) It's okay, it's a fair question. Tell us and we'll tell you too, lol.
Kenichi: (with Maya, every day, but I can't tell them that) Alright, fine. It's been a few months. I haven't had the chance. I haven't been to any clubs recently and the girls at the university are usually pretty stuck-up.
Suzu: I can't imagine that, you're quite the cutie. And besides, you're just a bit nerdy, not some loser. Girls like smart guys nowadays.
Yuto: Yeah, you've got lots of options. You should totally ask a girl out, man.
Kenichi: (Maya is enough, I have no need for a human girlfriend) Sure, whatever, it's not like I've been thinking about that recently.
Suzu: (he's lying, he's blushing) Hmm, if you say so. Anyway, we had sex this morning.
Kenichi: I'm sorry, what?
Suzu: Yuto and I had sex, we woke up early and started doing it. I promised we'd tell you if you answered, so... there.
Kenichi: (she's more open than I thought, this could be interesting) I thought you were just joking.
