The bodies of monsters have become specialized for effectively providing a man pleasure and milking essence. Inma thrive on sex, and their body is even more remarkable. We can say that they are beings whose entire body is an organ for milking essence and providing men pleasure. A inma's vagina behaves as if it clearly has a mind of its own, pleasuring a man to spur ejaculation. The mucus membrane engulfs the penis and pulses, and a man will easily be brought to ejaculation from the inhuman pleasure.
In synch with ejaculation, it will suck in the penis even more deeply as if to not let even a single drop get away, and it will move, stroking the penis until the very end as if to completely suck up even all of the semen that's accumulated deep inside. Due to that, ejaculating inside a inma's vagina will result in the release of such a huge volume of semen that it's incomparable to the situation of being with a human woman, or masturbation, etc. Along with a lengthy ejaculation, a man will experience a feeling like he's being completely sucked dry, and they say it's even possible for an additional climax and ejaculation to occur while in the middle of ejaculation.
A inma's mouth is for taking in and sucking a penis. Compared to humans, they have longer tongues, and just like their vagina, it has a mucus membrane that will provide pleasure by pulsing in sync with the penis taken inside. Sweet saliva is also secreted that functions as an aphrodisiac for humans.
If they squeeze the penis in their smooth palms, a inma's skin will greedily suck on it and caress it. If they put the penis between their voluptuous breasts, just like with their vagina, there will be pressure as if the penis is being held inside, and they will softly change shape to bring a man to ejaculation.
Since they sustain themselves with men's essence, not only the vagina and mouth, but any place on their whole body is also capable of absorbing essence with high efficiency and is equipped with a “sense of taste” for tasting essence. It goes without saying for the vagina and mouth, which are the places where a monster can taste essence most deliciously, but they can even deliciously absorb essence released in their breasts or hands, etc. Also, “mana”, which is the vital energy possessed by living things, is most highly concentrated in men's semen, but it's also contained in sweat, saliva, etc., and it is also something that is naturally continuously released from a man's body, though only in minuscule amounts. That is to say, although the best treat for the inma is when semen is ejaculated by their husband, the very act of joining together in sexual intercourse is itself a feeding activity in which they can deliciously devour their husband, and to state it further, even just by snuggling up to their husband and spending time with him, they can get a great feeling of ecstasy and satisfaction.
Succubi have devilish horns, tails, and wings. The shape of the horns on a succubus' head vary on an individual basis, but many of them have twisted horns. Among them, there are some who even have horns with a dangerous looking shape that appears sharp-pointed, but they are wrapped in protective mana so that they won't accidentally harm a man during sex, so there is no danger. Long, long ago, atrocious demons flaunted their power by having more sinister and wicked horns, but they say inma have them as a vestige simply because they derived from demons. Their horns don't have a sense of pain, but they do have a sense of touch, and according to the succubi, especially when stroked by the man who became their husband, it causes the inside of their head to feel “fluffy”, and it seems that it feels very good. They say that if their horns are squeezed by their husband when they're taking his penis in their mouth, the inside of their head turns to mush, and they can no longer think of anything but pleasure and the penis before their eyes. Since, no matter how strong-willed an individual she may be, most of the time a succubus in this state will single-mindedly focus on servicing the penis, at a glance, one might be given the impression that she has become submissive towards the man. However, in actuality, it's just like she's in a state where everything else is invisible to her, and she ends up attacking the man because the “inma's instinct” focuses all her thoughts and consciousness solely on pleasuring the partner before her eyes and milking his essence.
Their tails generally have a heart-like shape, and when inma experience arousal and desire towards men, their tails waggle in an alluring manner as if to express those feelings. As usual, its sense of pain is dull, but it is an erogenous zone that reacts extremely sensitively when touched, and it's even more sensitive the closer it is to the tip or base, and when squeezed in the hands or taken inside the mouth, the pleasure is said to be equivalent to having the same thing performed on a penis. When corrupting human women, they use it for things like binding a woman by wrapping their long tail around her, or rubbing against her to produce pleasure. On the other hand, the act of wrapping their tail around a man is proof of profound love. A succubus would only gently wrap it around her husband or the man she's considering making into her husband, and wouldn't intentionally let another man touch it. Conversely, when a man touches an unmarried succubus' tail, it will be interpreted by the inma as an invitation for sex to bring the relationship to a deeper level. Touching the heart-shaped tip area is a thing which is equivalent to courtship behavior and a marriage proposal to a inma.
Since they have wings, they have the ability to fly, but because of their size and structure, their flying ability is inferior compared to that of races that specialize in flight such as “dragons”, “harpies”, and so on, yet it is said that the way they look when they're shaking their hips as they fly is obscenely beautiful and can stir up men's lust. The distinguishing characteristic of monsters classified as inma is that they have wings growing from around their hips. The “hips” are the axis of their body that is heavily used during sex, and in line with this, their wings are also used for supporting their movement when they're straddling a man and shaking their hips.
