"Arrghh!" Bran groaned angrily. Arya had seen him. "Can't I have privacy?!" his voice was rough and he sounded a little out of breath. Bran was behind a wall, on his knees with his little cock pointed to the gods above. He kept his hand on it as Arya looked on. She had been wondering around the Castle, and certainly didn't expect to see this. She covered her mouth in shock. "That's disgusting! What are you doing with it!" Arya spoke in shock, taking a step back. "Oh, shut up and let me get on with it. If I can't do it here, I can't do it anywhere." he asked with anger, still wanking despite the girl being there. She was too stunned to reply. "It has to be done." he said, annoyed and panting slightly. Arya was a welcome sight, though he'd never admit that. Having his sisters eyes locked onto his small cock was quite the turn on.
Arya moved closer, curious. "It's small." she announced, almost with a smile. Bran flushed but didn't cover himself, he needed to cum. "Shut up!" he shouted at her, noticing the curves of her tiny body. "What you thinking about?" she asked him casually as she took a seat on the ground in front of him. "What do you think?" he said shyly, with a flush. His foreskin was soaked with pre-cum. Arya's eye sight zoned in on the head. Bran's little balls flapped around as he wanked himself off. "Well, girls. Or maybe boys, who knows with you." she said with a giggle, licking her dry lips. Bran went red but continued to wank. "Go away, will you?" he asked, his hand never leaved his dick. "Fine.." she began, and went to stood up. "No!" Bran said suddenly in protest. Arya raised her eyebrows at him, and Seven Hells did that facial expression turn him on.
"Tell me what you're thinking about." Arya demanded. "Mother in the bath naked." he confessed with shame. The truth is, the only women Bran knew were in his family. He couldn't imagine anyone elses faces. Arya's eyes widened in shock, but his cock felt too good to stop and he didn't care. "Gross!" she squealed. "Well, at least you're not thinking about boys." she said, but Bran gave no response other than re-gripping his small cock and continuing to jerk it. He was moaning softly and breathing heavily, loving every second that Arya watched. His eyes glanced over her body, stopping at her chest. She had absolutely nothing in the way of breasts, being so young. "Mother has the best tits in the family. Sansa second." he said, whimpering somewhat. Arya fidgeted with annoyance. "Mine are good, too!" and as she said this, she lifted her top clean off.
Her skin was a little rough, but deliciously pale. Her chest was completely flat, but her nipples bright pink. She was blushing terribly, realising what she had done. Bran couldn't take his eyes off his underage sisters flat breats. Arya went to cover herself, but Bran had moved over and stopped her. "What are you doing?" she asked in shock. She was completely exposed to her brother. "Even though you don't have tits, it still looks really good." he said, wanking his little cock even faster as he stared. "Quit staring!" she said, but made no move to cover herself. Her nipples hardened against the cold breeze. They were tiny, but rock solid. Bran used one hand to rub his cock, and the other to cup his balls. Arya couldn't help but giggle at the sight. Bran increased pace and Arya licked her lips.
"It's wet at the top." she said, moving her little cute face closer to inspect. Bran pulled down so his foreskin completely revealed the pre-cum soaked head. The wind felt nice across it and he moaned. "Why's it wet?" she asked curiously, and before he could answer she placed her small index finger on the tip. Bran began to tremble, he had never had his cock touched by anyone else. Arya, with a playful smile, ran her finger across the head and scooped up some pre-cum, toying with it's stickyness. The sensation had sent a strong vibration down the small length of his cock, and there was no going back from there. Bran began to whimper and wanked himself silly. "Watch, Arya." he spoke with a strained voice as his orgasm built. "Watch me finish!" he pleaded, pleasure in his voice.
"Oh gods, oh gods... oh, gods." his moans were just about audible as roper after rope of white cum shot out of his small penis. His sister watched on, her eyes and mouth wide open in shock. "It's pissing white stuff!" she observed as she allowed the cum to splash onto her thighs. Bran had the longest orgasm of his short life, right out in the open, right in front of his topless underage sister. He had been edged on by the sight of her flat chest, but her finger touching his little dick had really set him over the edge. He finally stopped cumming so he removed his hand, breathing heavily as he cock throbbed out every last drop. "Wow." Arya let out a noise of genuine amazement. "Was it me that made that happen?" she asked, stunned. Bran could only nod. He had never felt so good in his life. "Just wait until I tell Mum!" she spoke with excitement, raising herself off the group, topless still. Brans legs were too weak and he couldn't stand up to stop her. "No, don't!" he yelled in protest. Arya stopped in her tracks and turned around to face him, her little nipples bounced slightly.
"Our secret." he said, bluntly. His small cock had softened. Arya looked at it, blinked, then looked her brother in the eyes, rubbing her hand seductively across her nude chest. "Our secret."
