‘Influence’ her

"Okay Mina, first of all, you're going to strip completely naked." Deku ordered

"Yes. master." Mina lifted up her tanktop, causing her breasts to plop out and revealing she already wasn't wearing a bra. Next came her shorts, which covered some lacy, red panties, which she soon also dropped as well, kicking them to the side.

As Deku looked the clean-shaven, well endowed pink girl up and down, he put his plan into motion. "Mina, you are, and have always been, an exhibitionist. You love exposing your body to anyone and everyone. When you're alone in your room, you never wear a stitch of clothing. In fact, you absolutely hate wearing clothes or covering up in any way. Up until now, you've wore clothes around other people so that they wouldn't freak out or give you flack about it, even quickly throwing some on whenever someone knocked on your door, in spite our how much doing so bothered you. But you've decided that's starting tomorrow, you're done with that. You'll still wear clothes during class and if you have to leave campus, but in the dorms, you'll only wear at most a thong when walking around and you'll take off your clothes as soon as you enter the building. This is how you're most comfortable, understand?"

"Yes, master."

"Good. Now let's talking about sex. You are incredible casual when it comes to sex. Talking about it is like talking about the weather or what you're watching on TV, there's nothing shameful or personal about it to you. In fact, you're a big proponent for casual sex with multiple partners, both boys and girls. To you, so long as you don't hate someone as a person or find them too disgusting, you'll accept any offer of sex given to you. And you're fine with doing it anywhere and in front of anyone, no matter who they are or where you are. You also offer to have some form of sex with people as your default activity, courtesy, or reward. So, like, if you're bored, you might ask someone to buttfuck you, or if you have guests, instead of offering drinks or a place you sit, you might offer them to suck them off or eat them out, or maybe if someone helps you with your homework, you'll thank you with a boobjob. Just as examples, you can offer whatever form of sexual activity you want or however many you want to offer if they say no. And you're not obsessive when it comes to sex, you don't drool over people or pressure them into it, it's always just a casual offer, like offering to share food. Understood."

"...Yes, master." It took Mina a second to process all that Deku had said, but it was just a momentary pause.

"Okay, one last thing. If someone where to touch you sexually, you'll just let it happen without comment. You'll notice that it's happening and may even ask if they're done if they stop, but you typically won't care that it's happening. It's not that you love or hate being fondled, you just have no objections to it and accept that it's happening without question. You'll only really ask people to stop if they're in your way, like if you need to stand up or you're in a rush or something. But you won't be mean about it, it'll be like asking someone standing in front of you to let you pass. And this applies to anything from groping, to tit twisting, to fingering, to rubbing your ass, to spanking you, and anything else that falls into those fields. Sound good?"

"Yes, master."

"Now, summarize what we've gone over about you."

"My name is Mina Ashido, a lifelong exhibitionist who's finally fed up hiding who I am to make other people comfortable. Sex is great, it's nice having it as much as possible, it's the best way to beat boredom, say thank you, relieve stress, or even just say hi and bye. There's nothing personal about it, I'll do it anywhere and with anyone, except the creeps of course. Plus, I'm attracted to guys and girls. There's also nothing weird about being felt up, if people want to grab at my goods, why should I stop them? It's not like there's anyone wrong. Basically, I'm a sex object, and there's nothing wrong with that. It's just who I am." Mina began to form a smile as she said this and Deku noticed her starting to get wet.

With that set and Mina now basically a sapient sex-doll, Deku...
