Helping my seventeen year old brother...

Tess removed her white gown as she reached the bucket of water. Sliding the white dress drown, she found herself wearing a gray color underobe. From her top where she could see her nipples poking through them, while her undergarment - which was a simple frock - brushed against the hair between her legs. She removed each one of them, and stood completely naked on the small bathroom, which only consisted of the bucket, a well and a extended pole to hang clothes. 

Tessy looked down at her body. Her average breasts, soft nipples which were starting to lighten its colors a little and finally her bush. She touched the hair tenderly, thinking how much they had grown. It looked like an uncleaned forest down there, but there wouldn't be anyone to enter into her anytime in the following years. It was obvious. 

She felt warm liquid trickling down her thighs. She was urinating. It gave her a weird sensation but some sort of relief as well. While the yellow liquid oozed down her thighs she began to grope the black hair in her public area. For the first time, she noticed how soft they were. She might've stood there, lost in thought, touching her bushy bush, if someone hadn't knocked on the door. 

"Tess," Adrian's voice cooed behind the door. "I fell down." 

Rather than worrying about what he mentioned, Tess thought on something to cover herself. After a few seconds of thought, she picked up her undergarment wore it and raised it above her breasts. Her nipples - which were hardened for some reason, poked out of the dress but she didn't care. She had left too much time indulging on herself that she momentarily forgot the injured boy outside. 

Picking up the bucket and cleaning the urine on the floor with a splash of water, she opened the door and gasped in astonishment and guilt for leaving him alone for so long. 

"What happened?" 

Adrian was bruised with scars in his hands and his legs. His left leg was bleeding and he was snatching the wall for support. 

"Fell down from the horse after I tried to ride it..." 

"You stupid boy!" Tess scolded. "It's only you and me in the whole house, everyone is at Canberra Inn at Mrs. Isabella's party, didn't you think of the consequences?" 

"I just need to wash the wounds, I can manage until mama comes back." 

Tess scolded him some more before taking pity on the boy and helping him inside. Her bath could wait, she needed to take care of her little brother. 

"Hold me," Tess said. "I'll wash the wounds." 

Adrian grabbed hold to her, and Tess nearly fell from the weight of the boy. 

"Sorry," Adrian apologized. 

"It's fine," Tess replied. "You are really heavy?" 

"I'm touching you the wrong way, 'm putting all my strength onto you." 

Saying this, he lowered his hand and stepped forwards. Tess momentarily stepped forwards but couldn't match the speed of her little brother. This caused the boy to move forwards and loose his balance. To avoid the fall, Adrian desperately gripped Tess shoulder but his hand clutched her dress. As he fell, the dress began to tear up, and Tess's breasts popped out like two desperate creatures that had been suffocating under the gray robe. 

It continued to fall down but Tess, in panic let Adrian free and clutched her robe. The boy fell to the tiles but balanced himself from his hands. 

He looked back to see the tumult he had caused and saw her sister clutching a half torn robe that was held tight a few inches above her navel. But in her chest were the two inarticulable gems that managed to grip Adrian's pupils and keep them fixated on them. They were average, not bigger than their mother's but they weren't so shallow and hanging as hers. It was as if those two had their own life, as they held tight to her chest with two pointy edged soft objects at the center of each of them. They seemed to be so soft, as if something that's lost all of his innocence. Behind them were her areoles, that were too big for a age, but gave a picturesque backdrop to the soft seductive weapons. 

"Adrian!" his sister's voice brought him back to proper consciousness. 

He stepped back, in fear of her voice and tumbled into her other garments that were hanging in the wooden pole. He once again fell along with them onto the wet floor. This time, the pain that had been subdued flared up. He let out a painful cry and felt the tears brimming in her eyes. 

What overcame Tess was sisterly compassion. It had more larger claws than her embarrassment, and she rushed to her brother's aid, and gripped him tightly. Her nipples touched the boy's skin, and Tess felt a weird sensation over her. By the time she had crouched low to grip her brother, her cloth was on the wet floor, exposing her complete skin in front of the sixteen year old boy. 

She withdrew immediately, and picked up the towel, which was dripping wet. She covered herself once again, color rising up her cheeks. Her brother kept staring at her, with his eyes filled with lusty green. 

"Adrian, you can clean yourself right?" Tess asked, out of desperation. 

The cloth was wet and she was only covering her front. Her buttocks were exposed but Adrian couldn't see them. Buttocks were the same, Adrian had one too, but the boys didn't have two oranges popping out of his chest nor a under region that was worser than a swamp. Perhaps not the same buttocks as Tess. Once her mother had called her buttocks too fleshy, and it wasn't her fault that the back region of her skirt was popping up because of those two fleshy rear parts. 

Adrian touched his trousers and dropped his hand into it and tried to stand up, but fell down once again. 

Tess took this chance to fully wear the cloth again. She flashed full frontal for one second before eagerly wrapping the robe around her body. The cloth was wet and sticked to her skin like glue but she was covered and that was enough for her. 

She slowly advanced towards her brother, for obvious reasons, their relationship as brother and sister seemed to be a little deteriorated. 

"Where does it hurt?" Tess asked, gently touching his brother's leg. 

"Trouser," Adrian pleaded. "Help me move my hand." 

Tess slowly touched her hand, and the sensation inside Adrian's trouser seemed to amplify. He was wearing an underwear and his penis was erecting faster than he could blink his eyes. With her sister touching his hand, he felt like he could move the hand from the wounds. He slowly moved his hand to the trouser and pulled it a little down, revealing his underwear which seemed to tear itself apart from the pressure from his penis. Seeing the sight, his sister quickly removed her hands, but Adrian was fine now that he had moved his hand to his underwear. It was embarrassing to pull out his penis in front of his sister but he couldn't bear the pressure. 

He pulled down his pants and the troublesome penis sprang out like a long pole, it's tip pointing at the roof. In the edge of it was a small drop of white color liquid. Adrian felt it escaping when he saw her sister's curvy bosoms but it was just a drop, and he had more other issues to be worried about. His sister was glancing at his penis, with a expression of anger and astonishment. 

Tess didn't know what to do. The situation had got more embarrassing than she thought. And what her brother had just pulled out was what attracted her eyes. She had once or twice seen a penis, but things more larger than that. But this was more like a polished pole rather than something ugly. And her brother had come. The singular drop of white semen at the top of his trouser told the story. He had came after seeing her body. 

Despite the situation, his penis looked cute, and Tess couldn't find any other word in the vocabulary to explain the situation. 

Her brother lifted his painstaking hand and began to wag his penis to and fro, trying to removed the drop of cum on the edge. After seeing he didn't succeed in the attempt, Tess picked up one of the wet rags and placed it in top of his penis. Adrian removed her hand and the erected creature began to waggle as Tess wiped the cum away. Out of annoyance, she touched the penis, to stop it's motion. 

"Tess…" her brother's tone was pleading. 

Something fell on her hand, and Tess found out more white semen coming out of the tip of the little creature, but with much more force. It spilled on her hand, on his legs, on the floor, on Adrian's shirt. The boy couldn't stop it. You cannot stop it after it's coming. While her sister's hand desperately tried to stop the penis from moving, the thing began to pump out cum with the touch of her sister's hand. 

It only continued for two seconds, before it finally stopped. Tess looked at the hand, now with drops of her brother's cum scattered in her hand. 

No one talked for a few seconds. 

"Adrian," Tess took her hand away. The penis was still pointing upwards, as if it was unable to accept the accusation. "What have we done?"
