She makes her move on him.

Jenny didn't answer Marcus' hesitant question. Instead, she just kept pulling off her armor, right in front of her shocked little brother. Soon, the steel plates lay in a heap beside her, along with her belt and sword, and all she wore was a thin tunic. It was cut very high up her long, muscled legs. The young prince found himself staring right at his older sister's toned thighs, unable to look away. Her skin was just so pale and smooth. He couldn't help but imagine what it would feel like to kiss her there. Suddenly his mouth was dry, his head spinning, and underneath the cover of his hand he could feel his dick getting even harder.

"Lie back on the bed, little brother." Jenny murmured, her voice trembling in a way that made his skin tingle. "I'm going to make you mine." Marcus felt his mouth drop open. He glanced at his sister's face, and shivered at the heated look in her eyes. Did she really mean...that?

"Jenny..." He whimpered, shivering at the needy aching in his dick. This wasn't what he wanted, was it? They weren't married or even betrothed. He wasn't supposed to do this until then! And she was his sister too!

"Do as I say, runt." She snapped, pointing at the bed. "I'm not waiting for this any longer." The young prince swallowed hard. She was kind of scary like this, maybe he should just do what she said. It would be okay, right? If he was just doing what she said. The young prince sat back on his covers, one hand still covering his hard little dick. His cheeks were glowing hot, his skin tingling with a strange and worrying anticipation. He watched with anxious eyes as his sister stalked forward. Her blazing eyes were on his skin again, fixed between his legs."Move your hand." She hissed, sounding almost breathless with anticipation. "I want to see it."

Feeling like he was in some weird dream, Marcus felt his hand slip to one side. His dick was really hard, and he bit his lip at the way it throbbed and ached. He glanced shyly up at his older sister, very anxious at what he was about to see. Jenny was staring between his legs with her head cocked to one side. Her pale cheeks were flushed, and she was panting hard, the swell of her boobs rising and falling under her thin tunic. No-one had ever looked at the Marcus that way, so eager and hungry.

Suddenly she moved, darting forward like a pouncing cat. With a squeak of shock, Marcus fell back onto the bed. She was on him in a flash. Her hands grabbed him by the thighs, callused and rough on his soft, pampered skin. She spread his legs apart like he was a doll, so strong he knew he had no hope of stopping her. He could feel her hot, gasping breaths, tingling on the aching head of his dick.

"Please." He gasped, wriggling in her grip. "What are you doing?" A high-pitched squeal escaped his lips as she yanked him closer, dragging his whole weight over the blankets with ease.

"I told you, brother." She panted. "I'm going to make you mine." Suddenly her hand was on his dick, fingers wrapped round the shaft. He bit his lip hard. Just her touch on that sensitive skin sent naughty flutters all through his body. She wasn't even moving, just holding him there and staring at his cock like it was the most amazing thing she'd ever seen. "Fuck, you're so beautiful." She breathed. "All these years, I never wanted anything but this."

"Jenny." Marcus wriggled a little, his dick twitching in her gentle grip. Her hand felt really good, but...she was his sister! "I'm not...I don't think we should do this." Jenny paused, her gaze flickering at last to his face.
