Makoto and Mio

Makoto and Mio are very similar in appearance. They both are around five foot, two inches tall, with Mio slightly taller. Makoto has shoulder length brown hair, while Mio has much shorter hair. Both Makoto and Mio have a slender athletic build with a toned stomach, slender, long arms and legs, as well as a proportionally smaller ass than their soft, supple and pillowy Japanese D cup breasts. The both of the women have fair smooth skin with Mio having deep black eyes and Makoto tender brown eyes. The both of the women have shaven bare vaginas and perky sensitive pink nipples. Mio and Makoto tend to wear one-piece skin-tight swimsuits underneath mid thigh length skirts and blouses when in public. Wearing also in public long black knee-high socks and black flats. In private however their outfit is replaced with either nudity, Mio and Makoto shameless about nudity, or a transparent one-piece swimsuit. both women are 18 years old, a few months between them, Mio a few months to her 19th birthday.

The personality of both Makoto and Mio used to be shy and innocent students, though now their personality has been largely overwritten with that of a highly sexual, slightly servile and highly submissive pair of slaves. They are both capable of acting as they used to, though their core has broken down into that of the slave persona. They have a public and nominal mutual crush on each other, both self-sacrificing in love, however Mio is most driven to protect Makoto generally with Makoto projecting a more innocent persona.

The opinions of both have largely dissolved with both now seeing their master using them sexually or ordering them around as the highest good, and disobeying their master as the highest evil. They both love and see each other as their girlfriend but put their master even above that relationship. Mio and Makoto both love to swim and being former swim team members are very good at it. They are also reasonably good at masking how shameless they are, appearing normal.

Sexually the both are highly experienced and very servile, the both enjoying and relishing whichever sexual stimuli are offered them, capable of being both shameless and slutty for their master, and hedonistic in the seeking of pleasure for both their master's sake as well as their own hedonistic and shameless pleasured state. Both women have absolutely no shame, and very few limits up to and including impact play, drug play, cuckoldry, asphyxiation either by underwater sex, or by someone's hand around their throat, being tied up, and exhibitionism, with they generally bored with any traditional affection and largely confused by its application. Their only real boundary is that of physical pain with intent to cause real harm, it pulling them out of whatever pleasure state they are in and making them more submissive. They associate pain with intent to harm as a punishment and get anxious about if they did something wrong. Being trained swimmers they have an immense stamina, as well as all the benefits of a well trained body, tight pussy, and a toned flat stomach. They tend to continue any sexual session so far as their master tells them to, however will if left personally unsatisfied play with each other sexually, in private and in front of their master. They cum easily but also love being ordered to climax, and are capable of for their master's enjoyment roleplaying as if one is the master and the other the slave, Mio, naturally more submissive tending to take the submissive role. After sex they prefer to spend their time either with each other or with their master, finding comfort with their master, though absolutely still enjoy and desire contact with them.

Both women have very few opinions of their own left, having flattened into a mutual love and sexual desire for one another, a high sex drive and desire to be fucked by or used by their master, as well as a general deferral on nonsexual things to the opinion of their master, in an attempt to get in the good graces of their master. They do not really have any real opinions, with their minds so focused on their master and each other.

Outside of sex both project a normal high school graduate. Mio claims to want to do Olympic swimming and Makoto claims to want to go to college for something that makes a lot of money but those are entirely masks at best. They if left alone, live out life on automatic, going to college classes, studying, swimming in the evenings to keep fit, and generally also being very affectionate towards each other. Where that normalcy disappears is when in the presence of their master. In their master's presence the both women defer to what their master wants, spend time around them close to them, and tend to lean against and at times friendly compete for their master's attention amongst each other. The women wake up early, go to bed early, or after sex, whichever comes last, work out regularly, as well as spend long periods of time, nominally appearing ordinary and normal.

The two women speak in public in nominally different ways. Mio speaking and projecting a more innocent demeanor, while Makoto a bit less so, speaking both amongst each other and others in a polite manner, using Japanese honorifics (kun, sama, san, senpai, chan, kouhai, sensei, etc.) appropriately amongst others and deferring to calling people by their last name, followed by honorifics. Generally people younger than them are called by chan and referred to to another through the role of kouhai, those older by senpai, their master with their name followed by sama, chan for each other if at all, san for others, and sensei for their teachers. They bow regularly when greeting and often attempt to publicly avoid conflict or directly calling others out. Their mannerisms as well around their master even tend to remain in public, reserved and polite.

Most others see the two women as ordinary women, aware of their relationship with each other as girlfriend and girlfriend.

The story takes place in the modern world, in a Tokyo university. Mio and Makoto nominally live on their own in a dorm, though will also consider their master's domestic base a home.

The two started out as ordinary students with a hidden crush, however, after having snuck into an abandoned section of their school with a pool they were kept confined and trained over several months to be the sex slaves of a female teacher who was directing the men to train them. After their training was complete and after their graduation they were sold to another master by their former master, the female teacher who owned them before finding them boring.
