Halfdan staggered back to the cabin that he was sharing with his brother in Kattegat, a smile creeping onto his features, as with every step he got closer to finding himself walking in on something that he had walked in on, on more than one occasion, before. Harald had excused himself some time earlier that night, but as he left the hall, he had not been alone; oh no. For since meeting (Y/n) in Ragnar's domain the last time that they had been there, Harald had never been alone. Halfdan sure that it would not be long before his brother would ask the quite beauteous and rather regal looking shieldmaiden, to be his wife. And Halfdan was sure that this time, the woman that his brother had chosen, would truly make him happy. But for the moment at least, everything was just fun; and Halfdan wanted to share in that fun.

When he had first walked in on Harald and (Y/n), Halfdan had thought to immediately excuse himself. Yet as he stood in the doorway, (Y/n)'s eyes on him as she held herself on all fours; Harald behind her with his hands gripping firmly onto her shoulders pulling her roughly back to him, groaning as he watched himself move in and out of her. Each firm thrust bringing him closer to the edge; Halfdan found that he couldn't leave, that he didn't want to leave. The younger son of Halfdan the Elder slowly moving into the room and closing the door behind him, as (Y/n) eyes seemed to beg him to stay; to not stop watching. So, he had obliged. His eyes never leaving her body as Harald continued to fuck her. His brother saying nothing, just seeming happy to allow his lover what she wanted, as he carried on pleasing her. Halfdan unable to just stand there and watch for too long, his fingers pulling on the strings of his breeches, so that he could take his aroused manhood from its confines and begin to firmly stroke it. The sight of him bringing a seductive smile to (Y/n)'s lips; seeming to make her do things to herself, that were meant for his eyes only. Her movements, her glances, the sweat glistening on her skin and slowly trickling down between her breasts, pushing him to the point that he had been unable to stop himself from coming, when she had shouted out in euphoria at Harald's actions.

Finally, Halfdan reached the cabin; not even bothering to knock as he pushed his way in. His smile getting even wider, as he saw in the dim light of the fire, (Y/n) sat atop his brother. Harald gripping firmly at her hips as she writhed and moved up and down on him. The elder man just letting out a slight grunt as his brother moved one of the chairs so that he could get the best view of the shieldmaiden.

After that first night, Harald had informed Halfdan of (Y/n)'s confession, that she had liked him being there, liked him watching. That she had loved seeing him pleasure himself as Harald had gripped at her shoulders and then at her hair, roughly taken her until she could do nothing but scream out Harald's name in pure bliss; and given that the king wanted nothing more than to see the woman that he loved, happy, he had agreed that Halfdan could watch her, whenever he wanted to. That his younger brother could look but never touch; that right, the right to know what is felt like to be inside her, reserved for him. Halfdan readily agreeing; not about to give up the chance to watch (Y/n) again. So here he was, his tongue licking his lips, as he took his seat; Halfdan quickly moving apart his breeches so that he could take his manhood in his hand. The sounds of her moans, already making him hard and his cock weep.

He of course wanted more, what man wouldn't; (Y/n) was the perfect mixture of hard and soft; fierce fighter and woman. She was a warrior, and her naked body proved it. Arms and legs toned from years of practice with her sword and axe; yet her breasts, hips and buttocks still retained the curves of her femininity. Halfdan always imaging that it was his hands that were kneading her breasts as she moved her body atop his; that it was his tongue, his fingers that were tasting her, exploring her womanhood. His hand wet from her arousal as he made her cum before he had even been inside her. Yet he would take this; happy to watch her, to hear her, to smell the scent of her sex in the air. A heavy groan leaving his lips as his grip on himself got a little tighter, his thrusts into his own hand a little more desperate. Halfdan closing his eyes and allowing his head to drop back, sure that every time she said his brother's name; every time that she begged Harald not to stop, to make her cum, it was actually him that she was speaking to. Him that she wanted to spill himself all over her, to have his seed slowly trickle down her throat. The scene before him; the images in his mind bringing him closer and closer to his moment. Closer and closer until he could only cum over his bare stomach and wish that it was her breasts. Halfdan quickly opening his eyes and looking at (Y/n) and his brother, as the shieldmaiden let out a lewd moan. The younger man sure that she would come undone at any moment; and as she turned her gaze from Harald to him for a mere moment, there it was. The two seeming to tumble over the edge together, with Harald following close behind. Halfdan grunting loudly, as with his last few thrusts he bucked his hips firmly upwards. The air now quiet except for the sounds of their heavy breathing. (Y/n) giving Halfdan one last look, one last smile before she dropped to the mattress and moved into Harald's embrace. A smile coming to the blonde Norseman's lips, before he rose from his chair and made his way to his bed, sure that he would be happy to watch (Y/n), for as long as she wanted him to.
