Her own younger brother Vander...

A sudden visit to the capital castle by someone familiar to the queen prompted her to make an non-trivial decision for her secret plan.

Who is this "guest"?

Vander Glanef is the queen's younger brother, a teenager of 15 years old.

He arrived accompanied by a small retinue because of some important assignment from his father.

The visit of the younger brother prompted the queen to think about some things...

Her own younger brother Vander had always loved and desired her… being of noble blood he could produce a heir in the family and the act was so taboo… she could count on his discretion. Vander really was the perfect solution to her problem, and of course he was a horny teenager.

Lord Vander, the young nobleman, had always lusted after his beautiful older sister, the Lady Isolde. He'd caught glimpses of her creamy thighs as she walked by his room and often found himself touching himself while imagining what delights her body could provide.

Isolde, too, had noticed Vander's wandering eyes and the impressive bulge tenting his trousers. The taboo allure of taking her brother's virginity had often crossed her mind, but she never dared act on it until she needed a heir.

One evening, as the castle slept, Isolde snuck into Vander's bedroom. The moonlight caressed her curves as she slowly peeled back the covers and slipped in next to him. Vander awoke with a start, his heart racing when he saw his gorgeous sister in his bed.

"W-what are you doing in here, Isolde?" the horny young lad asked, his voice cracking as he saw her.

Isolde ran a finger down Vander's bare chest. "I need a heir, little brother. I know you're the only one I can trust to give me a child. I need you to take me, now." Isolde purred seductively, sliding under the covers. The heat of his bare skin seared her as she pressed against him.

Vander groaned, his cock already rock hard and leaking. Isolde's hand drifted lower, wrapping around his thick shaft and stroking him to full hardness. "I'm going to make you so happy Isol..." he stammered weakly, before kissing her full red lip's eagerly... a moment later those lip's moved lower.

Vander bucked his hips, fucking his sister's face as she slurped and sucked. Isolde gagged around his impressive girth, tears streaming down her face, but she didn't let up. Her pussy throbbed, juices trickling down her thighs at the taste of her brother's cock.

Isolde released Vander's spit-slick cock and straddled his hips, grinding her soaked pussy against him. His hands grabbed her ass, fingers digging in possessively. She reached between their bodies to rub his swollen tip through her slick folds, coating him in her arousal. Vander shuddered and bucked up, trying to thrust into her welcoming heat.

"Please, Isolde…" he begged, voice raw with lust. "Let me put a bastard in you. I've craved your cunt for so long…"

"Mmm, such eagerness," she purred, lifting up to position him at her entrance. She sank down slowly, a drawn-out moan escaping her lips as he stretched her deliciously. "Ohoho, you fill me so full…"

Vander's hands flew to her hips, holding her in place as the final inch disappeared into her clinging heat. They were joined completely, her walls fluttering around him.

"Fuck, sister… So tight and wet, like you were made for me…" He rolled his hips, stirring his cock deeper.

"Yes, only for you, brother," Isolde gasped, undulating on his shaft. She rocked faster, finding a rhythm. "Mmmph, I'm going to ride you until you flood me with your seed. Give me every last drop…"

Vander groaned, thrusting up to meet her downward strokes. The wet sounds of their coupling filled the room, skin slapping against sweat-slicked skin. Isolde threw her head back, crying out in ecstasy, her pussy clamping down on Vander's pounding cock as her orgasm washed over her.

"Yes, fuck yes!" He gripped her hips harder, pounding into her spasming cunt, chasing his release. "Take it, take your brother's cum!" With a roar, Vander hilted inside her, his cock jerking as it painted her womb with his potent semen. Isolde collapsed on top of him, trembling from aftershocks, milking him dry.

They clung to each other, chests heaving, as the forbidden bliss faded into sated drowsiness. Isolde smiled, already imagining the bastard child she would carry… and how soon she could return to her brother's bed to conceive another.
