Klingon: Fearsome humanoid warrior race in the Beta quadrant. Both male and female are bipedal with a sagittal crest, beginning on the forehead and typically continuing over the skull. A Klingon cranium possesses a feature known as the tricipital lobe. On average, Klingons are larger and physically stronger than Humans - their surface body is reinforced with an exoskeleton protecting vital organs and the spinal column, though they possessed a much lower tolerance for cold weather. Compared to their human counterparts, Klingons are approximately 30% larger and heavier. An average adult Klingon male is 6'6" in height and weighs around 320 lbs. An average adult Klingon female is 6'2" in height and weighs at around 250 lbs.
Klingons have different, not fully compatible reproductive organs than Humans. The mating rituals of Klingons are considered by many races to be abusive and violent. Klingon females are nearly as strong and durable as the males, and even among a purely Klingon couple, mating usually results in minor injuries to both parties.
While human males possess 2 testicles, and females 2 ovaries, in Klingons males have 3 testicles, and females 3 ovaries - part of Klingon evolutionary biological redundancy. A Klingon male has a permanently rigid penis with protective scales not unlike the shell of an armadillo. Average length is 12". A Klingon female vagina is a contractible but rigidly ribbed tubule similar to a vacuum cleaner hose. The vaginal ribbing is designed to contract around and interlock with a Klingon male's penis ridges - successful copulation requires genital locking. Once a Klingon penis is locked in intercourse, the Klingon female will secrete several lubricated cervical micro-tentacles which lasso around the head and shaft of the penis to secure the genital locking, increase chances of fertilization by semen filtering, and provide extreme pleasure to the female. These micro-tentacles can extend outside the vagina to guide in a penis and assist in genital locking.
During normal consensual coitus, the Klingon male vigorously thrusts his penis to actually try to break free of the ridge-lock as well as the coils of micro-tentacles. The out-strokes provide stimulation along the head of the penis necessary for ejaculation. Reciprocally, the in-strokes of the penis head against the ganglia of micro-tentacles can produce orgasm for the female. It is this tug of war between the male's penis and the female's ribbed vaginal walls and prehensile tentacles which the Klingons call 'The War of the Many' (1 penis vs all the female genitalia). However, because of the rough texture of a Klingon penis, female orgasm is not guaranteed.
Thanks to the natural of Klingon reproductive physiology, oral and anal sex are unknown to their race. Sex positions are typically male-superior, though Klingons females are known to pin down and ride males of inferior houses or smaller statures when the purpose of intercourse is for the female's pleasure, not for reproduction. Klingon culture is lesbian-friendly. The female's micro-tentacles can be digitally stimulated to orgasm. Klingon females masturbate with fingers or with a naQHom - a dildo that is softer and more pliant than a Klingon penis. Klingon males officially do not masturbate as "self-abuse" or "self-pleasure" is considered culturally unacceptable. Males can be manually stimulated to orgasm though culturally this is considered humiliating in Klingon warrior code. Klingon history has numerous accounts of defeated Houses where male prisoners were publicly displayed, brought to their knees, and manually stimulated - the forced spilling of seed "puq pum" symbolically depicts loss.
During the Battle of the Binary Stars, Klingon cruiser Lomqa commenced extermination of surviving humans on remaining Federation ships. Captain L'Rell, she of House Mo'Kai, was looking through the wreckage of USS Yeager when she spotted the unconscious body of Lt. Ash Tyler. Realizing food supplies were low, she instructed her crew to take his body to her quarters. She had tasted human flesh before and it was not unpalatable.
7 hours later, after mopping up operations were complete, Captain L'Rell returned to her quarters to see Tyler stripped of his hated Starfleet uniform, tied, bound and still unconscious. Ship physician K'haal advised that Tyler had been cleaned and decontaminated before beaming onto her ship in case she was going to consume him right away.
Human males averaged 6', so L'Rell regarded the prone body of Tyler with curiosity and amusement. "Little people," she mused. She walked around the table where he was lying on his side.
"Human male. 6' tall. 180 lbs. Only injury is a minor phaser blast as well as a concussion." She stretched out her large clawed hands around the back of his head. I could crush his skull with one hand, she thought. "Human skull lacks Klingon density and ridges." She circled the table and reached out to feel his back and spine - she sneered, "Human spine completely without ridges. No scales or protective cartilage." She stroked him from his neck to the curve of his buttocks. "Humans are so soft and fragile!"
She continued to circle the table, and she grabbed his foot, "Chal! These creatures are soft!" With one long fingernail, she traced the sole of Tyler's foot. He had no armor anywhere. Everything about the humans are so soft. How could they be at war with such a jellified race?
Curiosity got the best of her. L'Rell rolled Tyler onto his back. She was genuinely surprised to see his soft worm of a penis and sack of testicles. Klingon males had long hard penises, ridged with cartilage, permanently erect and tied up against the waistband of their undergarment. The Klingon equivalent to testicles were inside the abdomen just below the base of the penis - not this floppy pink human scrotum that just invited damage and tearing!
She grabbed his legs and held them up so that she could examine him more closely. She ran her fingers along his hairy legs - she had heard that humans were descended from primates. She was curious now about human anatomy. And she was also a little hungry.
After a thorough examination of the unconscious human, she kept going back to his soft bud of a penis, wondering how humans mated. To initiate a Klingon mating ritual involved biting, punching, and the breaking of the mate's clavicle. Then, the Klingon male would aim his Da'oghlaHneSchugh and ram it into her och. The ridges of the male's Da'oghlaHneSchugh would interlock with the ridges inside the female och. If the female was fortunate, the male's Da'oghlaHneSchugh would stimulate her ghargh je tentacles to orgasm. Copulation would thus began in earnest until a biting signified ejaculation of the male's nIM - Klingon semen is dark orange.
With her perfectly sharpened fingernail, she poked at Tyler's soft penis. She wondered how human females could stuff such a soft organ inside an och for reproduction. L'Rell was not a scientist, but having this naked human male lying in front of her made her wonder about their enemy.
Tyler was slowly waking up. His head hurt and he soon realized three things. He was naked. His wrists were bound. And there was a Klingon female looking him over.
"Get away from me!" he yelled. He tried to kick at her, but she easily grabbed him by his ankle until he stopped.
L'Rell laughed, "Human, you are in no position to give orders." She walked around the table, enjoying his panic at his predicament. "I am Captain L'Rell and you are my prisoner. The rest of your crew? They are being tortured or eaten." She let that sink in as he struggled against his bindings.
Tyler yelled, "Untie me! Give me back my clothes! This is uncivilized! Even for a Klingon!"
"I have never seen a live human male this close." She walked around to face him and sneered at how he brought up his knees to protect his soft little genitals. To remind him of her strength, she grabbed both his ankles and held his legs up in the air. He flailed about, but he could not break free from her clawed grip.
"What is your name, human?"
