With Sylvanas watching from the side, Arthas fucked with even more vigor. "What is it?"
"I came to see my sister, not you. How can I talk to her with you like this?"
Sylvanas said irritably, watching that filthy, foam-covered Dragon plunge in and out of her sister's lower body, fucking her sister until she moaned continuously.
Her sister's shy face looked exactly like their mother's had when she was being fucked. She didn't understand. It sounded like her sister was being wronged, so why didn't she refuse?
She could tell that Arthas was very respectful of her older sister, except in bed. Normally, her sister held a great deal of power.
"It's... alright... little sister... what is it..." Alleria couldn't help but wrap her long legs around her husband's powerful waist, writhing her hips forcefully.
Her sexy toes curled, the arches of her feet forming into a curve. She was climaxing! Being ravished under her sister's gaze, this pleasure sent her into an instant orgasm!
"We need to clear out the Horde Scouts. We need to go deep into the Swamp of Sorrows. The situation there is rather complicated. I came to discuss this with you."
Sylvanas frowned, her eyes looking elsewhere, trying her best not to look at the area where they were copulating.
"Sylvanas, you don't want your sister to be fucked by me for two hours without end, do you?" Arthas suddenly asked. As he spoke, his pace quickened.
He fucked Alleria so hard she began to twitch. Sylvanas thought he was torturing her sister, not knowing that her sister was actually having an orgasm!
"What do you want!" Sylvanas cared deeply for her sisters and brother, which was why Arthas could threaten her.
"Come here, kiss me. Make me feel more intense, and I'll cum faster. Your sister won't be tortured for so long," Arthas said with a lewd smile. The continuous thrusts left Alleria speechless.
Alleria shook her head, trying to tell Sylvanas not to agree. But in Sylvanas's eyes, this was Alleria begging for mercy.
Her heart filled with even more disgust for Arthas. To be so disgusted yet have to constantly serve him—it truly made her feel utterly nauseated.
"You! You've gone too far!"
Slap! Slap! Slap!
Arthas thrusted sharply, tightly enveloped by Alleria's slick wetness. The feeling was fantastic.
The slapping sound of his scrotum hitting her vulva was so pleasant, like an aphrodisiac. A tingling numbness began to gather in his loins, and the head of his cock began to stir.
Her climaxing pussy was too tight, contracting unconsciously, the pressure from all sides making the pleasure even more intense.
Seeing the pained expression on her sister's face, Sylvanas sighed and silently walked over. Arthas instantly wrapped his arm around her, his mouth covering her lips. His large tongue tried to pry open her teeth, but Sylvanas kept them clamped shut.
Arthas's large hand squeezed her breast, while his other hand reached down to her crotch and began to knead and press through the fabric.
Sylvanas's eyes widened instantly as a never-before-experienced numbness swept through her entire body.
"You can't!"
"Mmph!" Just as Sylvanas spoke, Arthas's large tongue slipped past her defenses. It found her small, fragrant tongue and began to swirl around it, sucking on it forcefully.
The tip of his tongue teased hers, churning the saliva inside. His skilled teasing left Sylvanas somewhat dazed, and the fondling of her lower body made her feel like she had to pee.
"Here I come!" Arthas thrusted even harder.
Although Alleria was inwardly displeased that her husband was molesting her sister in front of her, she still lifted her perky bottom to allow her husband to penetrate her as deeply as possible.
His mouth was kissing Sylvanas's red lips while his cock fucked Alleria's pussy. His lower body bucked with increasing force, pumping and fucking her hard, each thrust plunging deep inside, the head of his cock ramming her cervix and causing Alleria to tremble violently, as if he wanted to tear through her vagina!
"Coming! I'm coming!" Arthas roared! His cock, swollen to its limit, was thrust to its deepest point, pressing against her cervix.
At that moment, the thick white fluid that had been building up shot out all at once!!!
It spurted out with powerful force!!!
The semen slapped against the walls of her vagina, the strong impact making Alleria's eyes roll back in pleasure.
Her uterus responded with waves of heat, her clear vaginal fluids mixing with the turbid, filthy white cum, soaking his cock in the mixture!
Huff! Huff!
After ejaculating, Arthas released Sylvanas and lowered his head to kiss Alleria tenderly.
Only then did Sylvanas come to her senses. Had she just climaxed?
Seeing her sister still kissing that bastard Arthas so passionately, she seemed to understand something.
This pleasure was unforgettable. No wonder her older sister accepted this man's demands for sex time and time again!
After a moment of tenderness, Arthas rolled over and lay on his side, falling into a deep sleep without even putting his pants back on.
His flaccid cock was still covered in vaginal fluids and some semen. It looked ugly, yet so enormous.
Alleria took a tissue to wipe her husband clean, then smiled and poured her sister a cup of tea.
"You'll get used to it. Your brother-in-law needs to mate with women regularly to vent his excess energy. This energy is very pure and very beneficial for women.
Father's medical treatment will depend on Arthas in the future. He has so much to do, even the Dragons need his help. Sylvanas, I'm sorry for dragging you into this. I apologize to you on his behalf."
Sylvanas felt a mix of emotions. "Big Sister, do you love him?"
Alleria looked at Arthas tenderly, her delicate pale hand caressing his face as she listened to his snores.
A seductive smile graced her lips.
"I love him, and he loves me. He loves you too. I can tell he likes you very much. I told him not to force you, but it seems he didn't listen."
Seeing her older sister so deeply in love, Sylvanas bit her lip.
"No, he didn't force me. He's a bastard, you don't know what he..."
Alleria shook her head, raising her index finger to her lips in a shushing motion, then smiled.
"I know. I also know about him and Mother. Mother told me she doesn't mind. She's just worried that you and Vereesa would be unwilling. If he wants to be with you and Vereesa, then please have him come to me and Mother.
Let us bear it in your place. After all, we all belong to him, the entire Windrunner family does. It's his right to mate with whomever he wants."
