Sexual Arts, also known as "In-Do" in Japan, is an underground sex combat discipline where mutual orgasms and *** intertwine—a so-called clandestine sexual martial art. True to its name "Arts," it's a battle between men and women competing in both beauty and obscenity. Due to its extreme nature, it's considered a forbidden technique in mainstream society, only viewable within a limited underground video world. In recent years, practitioners have become extremely rare, making it an unknown realm for most people.
One day, I met a cosplayer, and instantly fell head over heels for her overwhelming voluptuous body. In her words and actions, I sensed the distinct aura of someone experienced in In-Do. Curious, I asked, "How many years have you been doing it?" At first, she played dumb. But once I mentioned several key figures in the scene, she finally opened up and began sharing her Sexual Arts experience.
Hearing her battle record left me speechless. Her fights weren't mere sex—they were trials beyond the edge of orgasmic death, radiating an intense sexual energy only veterans possess. Just being near her could trigger an erection. She had risen through unified tournaments and even claimed the title of U.S. Champion. Listening to her story, I couldn't help but cum in my pants. I was terrified by her sheer class, caliber, and presence—she was on another level entirely.
After completing her warrior's training, she had been living quietly, avoiding public attention, but her perverted body continued craving stimulation. She confessed to hunting men in back alleys of the city at night, seeking dominant cocks. Yet, her overflowing sexual desire and stamina couldn't be satisfied by ordinary amateurs. By this point, I knew I couldn't back down. I resolved to face her in battle—the only In-Do practitioner in our circle, Rokutsu Mitsuho.
The battleground: the Infinite Mansion, boasting countless rooms. On the day of the match, as I wandered the vast estate searching for Rokutsu, I was shocked to discover that before our arrival, the cosplayer had already been pounded to multiple orgasms.
Still, I knew she wouldn't be satisfied. So I proposed a handicap match—two men against her—something strictly forbidden in In-Do. She accepted without hesitation, and we immediately attacked. We grabbed her massive breasts from both sides, kneading them fiercely, licking every inch of her areolas and nipples. Her hips trembled violently.
Seeing her reaction, I was certain—this was no ordinary woman.
Sexual Arts is a chaotic world where masochism and sadism collide. And this cosplayer? She was the champion of masochists—a true maso queen who gets hotter the more she's tormented.
Knowing this, we didn't hold back. No mercy, no counterattacks allowed. Finger-fucking her pussy until it gushed, then flipping her over for savage cunnilingus followed by brutal hand-fucking. Her depraved female juices erupted like a fountain.
Even after climaxing, she wouldn't quit—praiseworthy grit. Like a somnambulist, she grabbed both cocks and greedily pumped them. We moved rapidly through the mansion, escalating into close-quarters combat. In the living room, she was flipped onto the low table, taking deep throat and tit-fuck simultaneously. The cock head ground deep into her throat, making her sob and gag.
Once her pussy was ready, we slammed into her bareback, penetrating to the deepest depths. Fierce piston thrusts drove her to scream, her vaginal ridges hyper-activating, every sensation rocketing into her brain as overwhelming pleasure. Unable to endure it, she climbed on top, grinding her huge ass in cowgirl, but we quickly flipped her back—her massive ass slapped like a drum, hands leaving red, swollen marks. And even that fueled her masochistic ecstasy.
Shamelessly moaning and screaming through consecutive orgasms—this was championship-level performance. Standing doggy while swapping cocks. Alternating between thicker, longer dicks, tearing apart her pussy's sensory nerves. Marinating her maso hole in flesh, then unleashing a thick creampie blast. Then using the creampie fluid as lube for another round, followed by a creampie facial all over her full, jiggling tits. She lapped up the cum with a satisfied, delicious expression. It was incredibly erotic.
