"Uuuungh, please, be gentle..." she moaned, rubbing her ass against the large bulge in his pants until Kenshin pulled away.
At that exact moment, the door opened, and Aya entered, gasping loudly. Kenshin had telepathically ordered her minutes earlier to grab lube and come to his workshop. The young beauty was thrilled and rushed over, expecting to fool around alone with Kenshin.
"Natsumi, what is this?! We agreed to always do it together!" she declared, annoyed at her friend's trickery.
"Ah, sorry, Aya, I couldn't control myself—you know how it is..." Natsumi moaned, growing even more aroused under her best friend's gaze.
"Aya, give me the lube and get beside her," Kenshin commanded, casting an appraising glance at the slender girl.
Under his gaze, Aya trembled and grew wet. She wore a pink T-shirt and tight blue Jeans. Kenshin loved everything form-fitting, so his women made a point to wear only such clothes, especially Hitomi. The other wives were insanely jealous of the big-breasted, curvaceous beauty who could distract Kenshin from work without issue, using it to beg for affection.
Aya knew exactly how to arouse Kenshin, so she elegantly approached the table, bent over, and thrust out her neat, toned ass, smiling triumphantly as Kenshin couldn't resist and grabbed her cheeks with both hands, making the young beauty moan sweetly.
"Aya doesn't know yet—tell her," Kenshin ordered authoritatively, returning to Natsumi and smacking her firm ass soundly.
"Ah! Kenshin's going to fuck us in the ass, girlfriend. Your secret wish is finally coming true," Natsumi said, giggling.
"You! Why do you always spill my secrets?! Kenshin, honey, don't listen—she's lying!" Aya whined, trying to rise, but Kenshin's right hand stopped her, pinning her to the table and smacking her firm ass.
"Quiet, both of you. Whose ass do I try first?" he said with a smile, stroking Natsumi's ass with his left hand and Aya's with his right. Both girls moaned softly and said in unison.
"Mine!"
"Aya, girl, sit and watch. You're next. No touching yourself, got it?" Kenshin commanded authoritatively, deciding Natsumi was aroused enough for anal.
Aya whispered "yes," stripped off her pants and panties, and sat in the Armchair, draping her legs over the armrests, staring fixedly at Kenshin with her lip bitten. In half a year living with him, she had mastered seductive behavior, leaving his self-control no chance.
Suddenly, a guttural moan escaped Natsumi as Kenshin's two fingers entered her ass again, followed by oily lube pouring in. He drenched her entire ass, unconcerned as excess dripped down her tender legs to the floor.
In one motion, Kenshin yanked down his pants and boxers; his incredibly aroused cock sprang free, slapping Natsumi's ass and making her whine with excitement. He immediately positioned it at her tightest, untouched hole, and she moaned even louder.
Meanwhile, Aya craned her neck to watch the moment such a big cock penetrated her best friend's tiny asshole. She knew hers was next and wanted to prepare properly.
When Natsumi felt the cockhead at her rear entrance, her eyes flew open, and she took a deep breath. The sensation was utterly unfamiliar and frightening.
"Shh, endure it, sweetie..." Kenshin whispered, leaning to kiss her sweet neck, soothing the young beauty until she relaxed and purred with pleasure.
He carefully inserted the cockhead into her tight hole, drawing a moan from Natsumi. She arched and tried to rise.
"Ow, God, it hurts!" she whined, but Kenshin soothed her again and waited for her to relax.
This repeated several times. Each time Kenshin's cock advanced a few more centimeters, Natsumi instinctively tried to rise, gradually growing accustomed to the unpleasant sensations. When his cock was about halfway in her tight ass, Natsumi fully relaxed, and the pain from the smooth thrusting faded. It was still a bit uncomfortable, but deep in her hole, an entirely new feeling emerged—something pleasant, different from her usual vaginal sex sensations.
Suddenly, for Natsumi, Kenshin thrust his cock balls-deep into her incredibly tight ass, making her scream.
"Aaaah! God, it hurts, hurts!" she squealed, but to her surprise, she felt an unusual wave of pleasure. Her pussy soaked even more, and heat flushed her body.
"Shh, the worst is over. Now your ass is finally mine. You're incredible, girl. Your whole body is a treasure..." he whispered, hugging her and placing both hands on her small breasts, kissing her neck.
"I can't believe your whole cock fit in my ass!" Natsumi exclaimed with arousal.
Kenshin barely restrained himself from grabbing her slim waist and impaling her petite body hard on his big cock. Her sweet words aroused him more, and with a guttural growl, he began moving slowly.
"Ah, God!" Natsumi cried, feeling the huge cock dominating her tight little ass.
He barely controlled his thrusts, using the scraps of his willpower to gently impale her fragile body on his cock, savoring her ass's tightness. She moaned from the mix of pain and pleasure, but soon began breathing heavily and whimpering. The pain nearly vanished, replaced by pleasure dozens of times stronger.
"Uuuuungh, God, don't hold back—fuck me, please!" Natsumi screamed, feeling an extraordinarily powerful orgasm approaching.
Hearing her best friend's words, Aya took a deep breath and barely resisted touching her lusting pussy. She never imagined anal could do that to a girl.
Kenshin grabbed Natsumi's hands and thrust even harder, pistoning his hips rapidly, plunging balls-deep into her tight hole with each stroke, sparking in her eyes.
"UUUUUUNNGH!" Natsumi screamed, trembling all over. Her eyes rolled back, tongue lolled out, and pussy juice squirted in a fountain. She had one of the strongest orgasms of her life, lost in ecstasy.
For Kenshin, it was the final straw. Her ass clenched so hard it milked every drop of cum from his cock, and he erupted, flooding her asshole with massive loads of semen.
"Aaaah!" he groaned from the unprecedented pleasure. His long-held desire fulfilled, he could barely stand from the overwhelming orgasm.
His cock kept pumping cum into her tight ass until it overflowed. Natsumi whimpered nonstop, trembling. Each spurt triggered fresh waves of unending orgasm, granting the beautiful girl even more bliss.
