I was 30 years old when I found the joy of writing in book margins and breaking the spines and I am never going back now, I am reborn. 😮 Seriously, fuck perfection. My new mission in life is to leave a mess behind me instead of always trying to be polite, small and convenient.

Ваше восприятие может оставаться постоянным, даже если само изображение меняется. Например, каждый раз, когда вы поворачиваете глазные яблоки, изображение устремляется по фоторецепторам с огромной скоростью. Если вы возьмете камеру и начнете водить ей по комнате, вы увидите размытые пятна. Однако когда вы двигаете глазами, окружающие объекты не скачут туда-сюда и не проносятся мимо вас с быстротой молнии. Мир кажется абсолютно стабильным – он остается на месте, хотя изображение на сетчатке движется. Причина в том, что зрительные центры вашего мозга были заранее «отключены» моторными центрами, контролирующими движения глаз. Каждый раз, когда моторная область посылает двигательную команду мышцам глазного яблока, она посылает команду и зрительным центрам: «Игнорируйте это движение; оно не реально». Разумеется, все это происходит без участия сознания. Данный вычислительный процесс встроен в зрительные модули вашего мозга и позволяет вам не отвлекаться на ложные сигналы движения всякий раз, когда вы оглядываете комнату.

Anger and Grudge
Anger and grudge, like acids eat the inside of a person and dissolve it. Betrayal is an acid that dissolves the purity of a person and destroys their relationships. Hurting others is actually hurting oneself. Most or all diseases are psycho-physical and originate from sins and wrongdoings.

Freelance Reflections #68
So, having reached a bit of a breather with work, I’m still tutoring in the afternoons, but have more time to read. As I’m still doing my music project, I’m reading various books about music and emotions. I hope to complete my research phase by the end of July to then record and put out a bonus episode reflecting on this. I’ve finished with my Macbeth students, and after one complained other…

It fucks me up that humans can't actually feel wet
We can feel temperature and texture so we can "feel" if something is wet but we don't have actual humidity receptors
Which explains the phenomenon of handling clothing that's been drying on the line and going "is this wet or just cold I can't tell"
I hate it and it fucks with my head

Tumblr media
«i'm so lost and confused / i don't know what to do»
«where are they now / i don't care anymore»
Tumblr media Tumblr media
Bioweapon —
USSTRATCOM — a place that gradually began to feel like a cage in which you found yourself due to your own choice, joining a secret unit on the list of a few more people in order to prevent the spread of bioweapons, devoting not only your body and mind to this cause — but also your life.
Contact —
Leon Scott Kennedy — the first person who took a step towards you and the first acquaintance that significantly smoothed everything that happens around you — to be honest, an awkward temporary contact with a fair haired man even pleased you, because your rare meetings and short dialogues made your thoughts switch to a slight smile playing around the corners of his lips as he jokes about an upcoming mission or discusses how he would like to go on vacation, and you, to be honest, too.
Zombies —
A defocused look and a veil before the eyes — not yours, but a rebellious creature in front of you, a twisted body and indistinct sounds that came from the mouth of an incomprehensible creature while its ragged movements and crooked legs carried it towards you in desperate attempts to get to you, only for your fingers to pull the gun trigger and fill the space with the sounds of gunshots, the bullets ripping through layers of already rotting flesh only to riddle the body of a creature that faintly reminded you of its human appearance, until it finally fell to the ground.
Blood —
Crimson thick liquid — it oozes like rubies from a limp body in scarlet streams along the floor and down to your feet, and you feel how strong and fast your heart beats arrhythmically, dispersing the blood through your own body with a loud noise from an overabundance of the body, forcing the whole body to break through weak pulsation, you don’t even have time to comprehend what is happening, as a heavy and itchy load immediately falls on your entire body, starting to feel cold sweat that collected in small drops on your skin, forcing your hands to automatically start trying to convulsively brush off the unpleasant discharge.
Nausea —
Unbearable pressure on the cranium — which seemed to have an impact on you from all sides, as soon as you look away from the corpse, your head starts to spin and your breath spirals in earnest, a disgusting lump forms in your throat and it seemed as if all space was leaving under your feet, and any matter around dissolving, followed by a vile, indescribable feeling that forced the body to strain to its maximum limit.
Panic —
An overwhelming feeling that sharply wedges everything around and is very blurry — you try to focus on the environment around you and you suddenly feel that you have nothing to breathe, in an instant you seem to be deprived of any access to oxygen, which, it would seem, should have been enough, your mouth opens in panic and in a futile attempt to swallow more air, but everything turns out to be in vain.
Comfort —
A sharp feeling of psychophysical pleasure and the opportunity to breathe — the necessary warmth began to spread through the body following the sensation of someone's arms ringed around you, someone's strong figure embraces you in an understanding embrace, as if only wanting to divert your thoughts from everything that previously worried you, and then a heavy hand lies on your back and begins to slowly draw ornate patterns with his fingertips
— «Shh.. everything is fine..»
the velveteen tone of voice helps to recognize in whose hands you are and the heart finally stops abnormally rushing around the chest, your breathing gradually returns to normal and in a matter of a moment the lump rolls back from a simple realization — you are in the safest possible place at the moment.
Monastery —
The long awaited feeling that falls on your shoulders and covers you with apathy like a blanket — a successfully completed mission safely returned you for some time to your usual state of affairs, being in the comfortable environment of your monastery and inspiring peace of mind that affects better than any medicine that helps excess weight and thoughts vanish from your body like something superfluous.
Alcohol —
Astringent and bitter taste that recreates a burning sensation in the mouth and further down the throat — an uncounted sip of ruby liquid makes the body perform an incredible somersault, thoughts turn into porridge and eyes get wet over an unpleasant veil that your obscuring gaze, because it is in such an environment that memories overtake you.
Aggression —
Discontent seething through the veins with hot blood, covering everything in front of you — your eyebrows frown after the hope that a few sips of alcohol will help you calm down and cope with painful thoughts, a glass of tart liquid is instantly emptied, your heart is convulsively knocking on your chest and blood walks all over your body with a familiar noise, and then you can’t stand it, with all your strength you hit the glass on the table, breaking the glass to smithereens, while your fingers instinctively clench around the fragments in an attempt to forget, injuring yourself on thin glass.
Return —
A confusing sensation of fussiness and unbearable tension — an unusual sudden fussiness and tight clenching of the lips until the pinkish skin turns white, new and uncomfortable feelings that arose somewhere on the internal soil due to the meeting with the long straight corridor that led to the oval office, provoking uncomfortable bubbling and noticeable lack of air to re-form deep inside, while the mind screamed endlessly that there was no place for weakness and your own discomfort, so the fingers had to slide along the bridge of the nose in an attempt to get out of the viscous shackles of an unpleasant foreboding.
Disruption —
Acute anxiety and inability to focus on the environment — as soon as you cross the threshold of the door out of the office on cottony legs, you already unconsciously rush towards any free room to lie down there until you come to your senses, until your vision swims worse than the raging sea waves followed by a sharp movement of your hand that pulls some unknown door handle for you to roll over the threshold and lock yourself between four walls, leaning back against a wooden surface and taking in air into the lungs.
Need —
Feeling unable to cope with what is happening on your own — fingers smear transparent drops of tears on your face before lifting your head and only then perceive the surrounding picture, in your most vulnerable and hopeless position you locked yourself in an unknown office with a man whom you had already allowed to probe your weakness — Leon Scott Kennedy, you know nothing about him except his name and pair of blue eyes that look at you in pure surprise, and you feel even worse from the realization that if he were to pull you to him again now, you would gladly give in to this impulse, but instead you stand with your back to him and tremblingly reach for the door handle.
Consolation —
A warm, honey like feeling that you succumb to and let yourself feel weaker than usual — only to hear an already completely unimportant document slap on the table before footsteps echo against your eardrums and you feel close contact with his warm chest before strong arm shamelessly wrap around your waist line, carefully and torturously slow forcing you, like a feather, to turn to face him, only to bury your face somewhere in his chest and at the same moment endless and unintelligible sobs pour from your lips, and the tongue unties itself, as soon as his voice with warm breath touches the shell of your ear
— «Shh, sweetheart, i got you.. i got you»
your voice is hoarse and torn after another sob, and you don’t care at what moment a gentle appeal sweetly slipped from his lips
— « I-I'm.. I-I can't take it, Leon.. I'm»
— «I know.. i know»
Attraction —
A blind reaction to the inability to think concretely — a ridiculous desire to remain in caring hands and sink into an unexpected need to feel his presence closer, to force all the disgusting memories to burn out of your head as your head slowly lifts up to meet his gaze with your tear stained eyes, and his hand is incredibly tender as he caresses your cheek and his thumb carefully traces a line under your eyes, collecting tears and watching your eyelashes quiver at the sudden feeling of embarrassment that has blossomed inside you and revealed a pinkish blush on your cheeks.
Awareness —
A complete understanding and acceptance of what is happening, penetrating the spine, an awareness of a need that rises above everything else — his head slowly lowers to face you, and a finger slides from your cheek to your chin to gently lift it, you catch a small quiver of his eyelashes before his warm lips touch yours in an uncertain kiss, and you don’t even have time to comprehend what is happening and the seething heat inside, which made your heart contract and beat not because of an unpleasant lump of feelings, but something warmer, and he pulls away with a half lidded eyes in order to cover half of his face with his hand, squeezing out
— «I'm sorry.. i shouldn't do this, probably, i should - »
he does not finish, because the realization hits you with pressure and you give in to the need, dropping your lips to his again.
Passion —
A strong impulse that is accompanied by an irresistible attraction to someone — something that makes you find yourself in his arms, seasoning your back against a cool wall, while his warm tongue greedily explored all the depths of your mouth and your sweet lips, pulling charming moans and needy whining to his ears — he is ready to give in to your every desire, drawing a path of kisses from your lips to your neck to paint it with bright buds of scarlet traces, a warm hand carefully pulls off your blouse to throw it behind your back, needing to touch your seductive flesh, teasingly swiping his tongue up your collarbones as his free hand gently yanks off your bra, making you whine
— «Please, hmn.. L-Leon..»
his voice is lower than usual, demonstrating a reciprocal need for contact as his tongue touches your chest and lightly brushes your nipples with his teeth, causing your spine to intuitively arch and your fingers to sink into his shoulders
— «Mm, sweetheart, just a little bit, want to taste every part of your delicious body..»
Lust —
The need for voluptuousness, sensual sexual desire from which all sorts of sensible thoughts float — the only thing that left room for thinking was how to cover every part of your body with his marks in order to squeeze out more moans and sweet sobs from you, and it comes out when he gives you what you wished for a long time, wriggling in his arms for closer contact.
his hand slid freely up your thigh, making your legs flinch around his waist, while his hand teasingly lay on your pubic tubercle hidden behind the thin, soaked fabric of your panties to run his fingers along your sensitive spot, listening to how his name slides from your swollen lips
— «L-Leon!»
he hums, turns his attention back to your face and in a quivering kiss covers your lips again until his fingers finally begin to make jagged and erratic patterns over the small pea of your clit, smiling into your lips as your back arches sharply and your head rises back, and he seizes this moment to slip outside of your underwear and pull the panties down, leaving them hanging from your leg while his fingers spread your labia minora to plunge one finger into your wet crotch, swiping and repeating fictitious movements in and out , until your hips begin to buck up intuitively, with every opportunity to move towards his caresses — and a smirk blooms on his lips, he adds another finger and watches your face writhe with an overabundance of feelings.
Euphoria —
An overwhelming sense of bliss — trembling into every cell of your body, making you tremble in his firm arms and sink your head into his shoulder as the walls of your cunt clenched and unclenched around his fingers until the sweet sensation of orgasm slowly subsided, allowing him to take his fingers out and bring them up to his lips, licking your juices utterly greedily, watching your cheeks redden shamefacedly at the sight of him savoring you on his fingers before sinking back into your joint kiss, letting you taste that strange taste on the tip of your tongue before moaning into his lips with not a request, but a sincere need
— «N-need.. need you..»
a low laugh sounds extremely languid, vibrating off his chest and allowing you to feel it to the fullest in connection with you being in his hands, while his whisper caressed your ear, swiping a wet strip along your ear lobe, drawing a sob out of you
— «Need what, hun? You need to talk properly, hm?»
the challenge in the tone of his voice makes you flinch, the desire to feel his cock deep inside of your cunt covered everything with a veil and pressure in the lower abdomen, provoking your tongue to untie enough to squeeze out embarrassedly
— «Need your c-cock.. inside, please.»
a satisfied smile stretches along the line of his lips so that he again covers her lips with his, soft and hot, weaving his fingers into strands of your hair and running between them with his fingers, while his relatively cottony legs from his own arousal lead him to a table nearby, Leon lays you on lightly cool surface before parting your lips and finally freeing himself from the stuffy layers of clothing.
Frenzy —
An extreme degree of mental arousal, a violent loss of self-control — a surge that makes him, with impatient and sharp movements, pull off his t-shirt and throw it aside, only to go down with his hand to the belt of his trousers, tangling his fingers in the buckle and deftly releasing it to lower the interfering fabric into floor, and all he needs is one quick glance at your glossy eyes that are following the movement of his hands and how he was getting close to the elastic of his boxers as if he play's with a cat, with you.
the nervous lump finds its way down your throat as you watch as Leon releases the rubber band and lets his cock slide out freely, causing him to shudder in contact with the cool air, revealing to you a view of his slightly swollen cock dripping with precum, his footsteps in your direction measured and feel like an eternity, until you feel his hands smoothly spread your legs, running his tongue over his lips at the sight of your shiny with arousal cunt, and the spine arches by itself as your hips thrust into his touch, and you hide your reddened face in your hands, suddenly feeling his lips on the skin of your neck, shuddering from his hot breath and sensual whisper
— «Don't hide your pretty face, darling»
he adjoins his sharp cheekbone to your neck and then leaves a smeared bite, leading a path of crimson hickeys and butterfly kisses to the line of your sharp collarbones and teasing them with his teeth, awakening in you an unbearable heat from the accumulated arousal that provokes you to reach down with your hand, groping for his cock and running a finger along his urethra, smearing precum all over it and getting out Leon's sharp growl, which is then covered by his deep voice
— «You want this so much, aren't you, needy thing?»
his tone of voice completely obscures your mind and ability to think concretely, so you foolishly nod your head and whine from a quivering kiss on the top of your head before he starting to act, slowly pushing his crimson head inside your cunt, marveling at the ultimate narrowness
— «F-fuckgh, sweet thing, you are so tight»
his movements are slow and measured, full of exhilarating excitement, before he picks up the pace and begins to move more boldly, pressing his hips against your buttocks, on which his large and slightly rough hands rested, as his cock plunged into your hot insides with each time faster and faster, watching with eyes covered with lust as your cunt sucks his cock into you all the way and shrinking as if refusing to let go, and his pace became almost animal, pulling out loud and hoarse moans from the depths of your throat, covering your mouth with his hand and whispering softly into your ear, while he slowly put your legs on his shoulders
— «Shh, sweetheart, don't want anyone to know what we're doing here, aren't you?»
and you nod dumbly again, feeling your legs rest on his shoulders as he rams into you from a completely different angle, hitting your kervix and enjoying your muffled moans and whimpers as you desperately try to mutter about the intense pressure in your stomach
— «Need t' cum.. pleaseleonwanttocum!»
he answers you with a deep growl before looking down at you and freeing your lips from his palm, replacing it with his lips to drown out your further cries of pleasure, whispering
— «Cum.. cum for me, let yourself go, yeah?»
and you writhing, moaning into his lips as he kisses you endlessly despite the catastrophic lack of air, while you ring his neck with your hands and let yourself arch, stretching like a string into a frenzy, while your knees convulsively trembled, and all the erratic moans driven by the wave of orgasm get taller, matching his by how much your cunt clenched around his cock.
— «S-shit, doll, not going to last m-much!»
you both moan obscenely loudly in unison, trying to drown out all sounds as much as possible, while your body convulses pleasure like an electric shock, he licks your swollen lips while your eyes roll back in ecstasy for a few moments, feeling Leon crush your thighs with rapture , feeling his orgasmic discharge approaching, he thrusts into your hot and dripping cunt one last time, and then ejaculates, staining the walls of your cunt with his hot ropes of cum before going limp and wrapping his strong arms around your body, pulling you closer.
Bliss —
A feeling of supreme pleasure, joyful and comforting — what you feel at last again in a long time, feeling him gently trace his thumb over the marks he covered your now limp body before pulling his cock out of you and kissing your cheek, hearing you whimper softly before snuggling closer to him from being so tired and wanting to stay in this trembling moment - so he gently strokes your back, lifting your chin to look at your tired sleepy eyes, which makes him mumble softly
— «How are you feeling now, hun?»
your lips curl into a warm, sleepy smile before nuzzling into his chest and muttering, hugging him as tightly as you can, clinging to your current situation
— «Good.. never felt so good before..»
those were the last words from you before you let fatigue and exhaustion get the best of you and pass out in his arms and gentle presence.

Please help!
I am fundraising for my good friend Zahara to help find her a place to live and have food. 3 years ago, their sister bought the house from her dad and didn't tell her. She is diagnosed with petit mal seizures and psychophysical insomnia which makes working normal jobs impossible for them. For the past 3 years she has been in and out of abusive housing situations, and their sister is removing them from their support system on the 19th of July, 2023.
Any donations, even $1, are heavily appreciated.
If you can't donate, spreading this around is also helpful.
I will even do some milestone art for it.
