William looked down with a giant grin, he loved the way he felt, but more than that he loved the way Elizabeth's skin picked up a soft glow after orgasm. Slowly, he slid his shrinking penis from her warm, pulsing pussy. His hot, salty juice trailing out after his soft pink head, trickling down across her still puckered asshole. Elizabeth's laugh was addictive. The way she giggled as the endorphins overloaded her brain.
"Oh William, I love you." She smiled, squeezing his muscled shoulder.
"You're so gorgeous Elizabeth," he leaned down, kissing her forehead.
It was a bittersweet meeting. As William stood and redressed for the last time, Elizabeth watched; her breath shallow and labored. He turned, winking, watching her bare body as her smooth skin glistened in the afternoon sunlight. Her bright red hair stood out against her pale white shoulders. Elizabeth's perky pink nipples stood erect in the warm light, begging to be licked and sucked. William could felt his cock stiffening against the fabric of his tight blue jeans.
"Just once more?" She begged, biting her lips. "William please?"
"Liz, I just can't. Katie Blake is set to arrive today, and you know how mother and father wish to show me off."
"Oh William, let's just run away. We've so been together since we were children, don't you like touching me?" She teased, running perfectly manicured index finger along her areola. William licked his lips watching her nipple harden under her slightest touch.
"I've got to prepare. Tonight though," he grinned evilly, his sentence trailing off as he turned to leave the room.
"Brother?" She called from the bed. As he turned she instantly spread her legs wide, burying two fingers deep in her swollen, shaved pussy. A loud moan escaped her lips as her fingertips pressed magically against her gspot. Elizabeth's pussy convulsing her juices spilled out trickling down across her thigh.
"Mmm, delicious." William kissed the air.
"Yes, it is..." Elizabeth licked the tasty juice from her fingers delightfully.
Walking from the closed door, William could hear the loud moans of his sister Elizabeth as she continued to play. The whole family knew it was William's turn. For generations, the Adams family had practiced arranged marriages. They believed that being true Royalty came with the responsibility of knowing where your bloodline runs. The truth is the bloodline had run dry. It was time for some new blood. If the Adams family line was to stay strong, they needed a new progeny. A new line that would outshine the old Adams line, take them into the future.
