More than a sibling's love

Marcus froze in his sister's arms, stiff and trembling as her lips pressed hungrily against his own. It felt like she wanted to swallow him whole, the way her mouth covered his. Her arms were wrapped so tightly around him he could hardly breath, crushing him into her armored chest. She used her lips to press his own apart, then he felt her warm, wet tongue slip between his teeth.

The young prince blushed red-hot. This wasn't a sister's kiss! This was a...naughty kiss, like the ones he'd read about in the stories which always made his ears hot. She was licking at the inside of his mouth, her tongue pressing against his own. Why would Jenny want to kiss him like this? His whole face was prickling, and the fluttering in his belly made him shiver. Even worse, the way she was holding him so tight and kissed him so hungrily was making some very embarrassing things happen under his shift. He wriggled against her as his dick stirred, hot little prickles running down his sensitive skin.

"Jenny..." The young prince breathed as they broke apart at last, strings of glistening saliva joining his wet lips to hers. He could hardly breathe. His blush had spread to his neck, prickling waves of heat flooding through him.

"I love you, Marcus." She murmured, her voice shaking. "I always have. And now you're mine at last...I can't...wait any longer." He hardly even noticed, but her hands were fumbling at the front of his shift. Only then she suddenly grabbed the thin garment by the hem and yanked it up, dragging it off his body before he could even squeal in shock. The young prince found himself standing naked in front of his older sister. A strangled gasp escaped his lips and his hand flew down to cover his aching dick. It was getting all hard already, what if Jenny saw?

His older sister straightened, holding the silk shift in her hands like it was some precious treasure. A shiver ran down her spine as she gently laid it on the floor beside her, neatly folded. Then her hooded gaze flickered back to him, drinking in the sight of his naked body. Those dark blue eyes wandered up and down his flesh, so hot and hungry it felt like they were about to burst into flame. Marcus trembled like a leaf. He could hardly even think. His head felt full up with a dizzying mixture of shame, nervousness and a tingling arousal that he knew he shouldn't be feeling.

He stared back at his sister, unable to look away, as she reached behind her and started undoing the clasps of her armor. Her steel breastplate came away first and she dropped it, letting it fall to the ground beside her with a loud crash. The sudden noise made Marcus jump, shaking him out of that strange fog that had swept over him so suddenly. His anxious gaze found his sister again. When he saw her fumbling with the straps of her belt he finally realized she was planning to get naked too! Right in front of him!

"Jenny!" He spluttered. "What are you doing?"
