He has to convince Jenny he cares more about her than anyone

"I can't let you." Jenny hissed, tugging Marcus even closer to her, holding him so tightly in her muscled arms it was starting to hurt. "I knew I shouldn't have kept Mother here. You like her, don't you? She's taking you away from me again! I knew I should have had her thrown out of the Kingdom and Father too! Or maybe I should just chop their heads off and be done with it. Then no-one else will dare try to steal you again!"

"Jenny, no!" Marcus gasped in horror. She was talking about...killing their parents, and she sounded so serious too! "Please...don't hurt them! Not Mother!" He was crying helplessly, terrified of how crazy she was acting. He couldn't believe this was his kind, strong older sister! What had happened to her?

"See?" Jenny sneered viciously. "Now you're trying to protect her! Don't lie to me again! She got to you first, didn't she? I know she wanted too! She fucked you, didn't she?"

"No!" Marcus sobbed. His Mother had never even touched him that way, but his sister didn't look at all convinced. She had a wild look in her eyes, her lips curled into a ferocious snarl. He knew with just one look at her she was on the verge of jumping out of bed and going to chop off their Mother's head right now. He had to stop her, but he had no idea how! "Please, Jenny..." He whimpered. "It's just because she's my Mother. You're...the only one I've ever been with, I promise you." Jenny paused, a moment of confusion flickering across her face.

"I wish I could believe that, little brother." She murmured, her voice trembling. "They kept me away from you for so long. You have no idea how painful that was, do you? Everyday waking up and knowing you weren't there beside me. You never tried to find me, did you? I was waiting for you, runt...waiting for so long, but you never came back to me. Instead you stayed here with her, with Mother!" Tears welled up in her eyes as she spoke, and suddenly she was crying too, hoarse, painful sobs that made her whole body shudder. Marcus gaze up at her, his sister in so much pain. His heart ached with sympathy even as afraid as he was right now. He wanted to help her, he wanted to make her see that she couldn't kill their parents like this, but he didn't know what to do. Then it hit him. She wasn't going to stop unless she knew she was the only one he'd slept with. He had to make her see he cared about her too!

"Please...please...I love you, Jenny." Marcus gasped, tears streaming down his cheeks. Wriggling up in her grip, he did the only thing he could think of. Pressing his naked body against her own, and kissed her firmly on her waiting lips. Her mouth was wet and parted, her blue eyes wide with shock as she gazed back at his. **** to make her see, he slipped his tongue inside her mouth, licking tenderly at hers the way she'd done to him. No matter that this was his sister, he felt his body respond, a strange, tingling heat fluttering in his belly and dick. He was getting hard again, as painful as it was after what she'd done to him last night. "I love you." He whispered as he withdrew from the kiss, staring into her glistening blue eyes.

"Marcus." She whispered, her body stiff. "You kissed me." Her hand slipped up between them, fingers brushing gently over her own lips like she was trying to convince herself it had even happened.

"I wanted to show you, that you're the only one." The young prince murmured, blushing furiously at the words. He wasn't lying. She was the only one he'd slept with, but he knew she was going to think he meant something else. Sure enough, she smiled shyly through the tears, her own cheeks flushing pink. She looked so very relieved, like some awful, massive burden she'd been carrying for so long had been lifted from her shoulders.

"I love you too, my dearest one." She sobbed, then she lent down and kissed him back, gentler than before, her one arm holding him against her like he was made of porcelain. Her hand rubbed his back, caressing his skin. Part of Marcus felt a little unnerved by how quickly she had changed from vicious anger to this fawning happiness, but he was so relieved she wasn't mad anymore he found he couldn't care. Instead he lay there and let his sister's tongue tenderly explore his mouth, trying to ignore how hard his poor dick was. At least she was happy now, right? "I'm sorry, my love." She whispered as she pulled away at last. "I just...I get so mad when I think of another woman trying to take you away. And Mother...she may not have done anything, but she wanted to. You're such a kind, gentle boy...and you don't know how awful women like her can be when they see something they want. She was the one who made Father banish me, I'm sure of it, to keep me away from you. That's why I don't think you should see her, okay?"

"Jenny, please." Marcus whimpered, fluttering his long lashes at her. "Can't I talk to her, please? I promise, I won't let her do anything! Please!" Mother didn't like him that way! It was just Jenny worrying about all these crazy things, right? He just had to make sure the Queen was okay.

"Fuck...I can't say no to you." His sister sighed. "Tomorrow. You can come with me down to the dungeons and I'll let you have a chat with Mother. Maybe it's for the best anyway. We can tell her what's happened between us, and make sure she knows you're mine now." Marcus glanced down anxiously at the thought. His Mother...wasn't going to be happy at all when she learnt what Jenny and him had done. Maybe the Queen would even be able to talk to Jenny and make his sister understand that this had to stop. He'd tried his best already and it hadn't worked in the slightest, but she had to listen to their parents, right? "I'm so sorry, my love." Jenny sighed, her arm slipping out from under him. "I have to go and see to the Kingdom again or my advisors will be furious. They're always bothering me with questions that should be so obvious. I don't understand why they can't just figure these things out for themselves." She let out a harsh breath, then managed to smile again at him. "While I'm away, I think it's time we move all your stuff over to my bedroom so we can share properly. I'll send some of the servants to carry all your clothes and things. Once that's done you have a bath and get yourself nice and clean and smelling pretty for me. When I come back later this evening, I'll feed you your supper and then..." She kissed him one last time, just a tender brush of her lips over the skin of his forehead. "We'll make love all night."

"Yes Jenny." Marcus nodded, blushing furiously. After what had happened yesterday, he wasn't sure he could take another night of what Jenny called lovemaking. Maybe now she was being nice, she'd stop and let him rest if he asked. She slipped from the bed and dressed herself, hurriedly pulling on her trousers and shirt. The young prince sat up awkwardly, his head spinning after everything that had just happened. He couldn't help but feel like this was spinning out of control, but he just couldn't think of a way to stop it. He watched anxiously as his beautiful sister turned and blew him a kiss, then bounced out of the bedroom, a smile of pure joy on her gorgeous face.
