Chapter 1

Frustrated, Noah slammed the front door shut behind him. His day had seemed to drag on forever. That the traffic on the way home was completely fucked after an accident, was just the icing on the cake. On the way home he really regretted that he hadn’t relieved himself before leaving school. Since he had spent more than half an hour extra on the road, his bladder now felt like it was about to burst. He shuffled quickly towards the bathroom, almost jogging.

When he threw open the door, the shock of the sight before him actually won out the battle for attention against the urgent longing to relieve himself. He had barged in on Emma, his 16 year old sister. She was standing in front of the mirror, her phone in her hand. Most importantly though, she was topless. For one second Noah got an unobstructed view of his sister’s breasts. Then she screamed, fumbling with her phone as she frantically tried to cover herself.

“Get out!” Emma yelled in panic.

“Uhm, sorry, I, sorry,...” Noah stammered, his eyes still focused on the parts of her bare breasts that Emma didn’t manage to cover. Finally he regained his composure and backed out of the bathroom, closing the door behind him. As he quickly went to use their parents’ bathroom, his mind mulled over what just happened.

On some level Noah had always known that his sister was beautiful. It was obvious to anyone with eyes. Her blond hair cascading over her shoulders in loose waves contrasted with her tanned skin and hazel eyes. She was slender, but athletic, with long legs that she liked to show off. But right up to this moment, he had always just thought of her as his sister, never “like that”.

Seeing Emma half naked had sparked a jolt of desire inside him. Even though it was wrong, he wished he had more time to take it all in. You know how they say it’s better to have loved and lost than never having loved at all? Noah wasn’t sure the same applied here. The quick glimpse of her body was a glorious event that he’d never forget. But knowing that he would most likely never see her magnificent tits again was also incredibly frustrating.

Leaving his parents’ bathroom, his mind struggled. He tried to banish all the dirty thoughts about his sister while at the same time, he was replaying the image of Emma’s breasts in his head, trying to etch every detail into his memory. Even that was frustratingly difficult, as the memory of her breasts was already starting to fade.

Back in his room, Noah realized he’d have a hard time concentrating on his school work. With a sigh, he took out his phone to check what he needed to do. Much to his surprise, his phone indicated that he had received a text from Emma. After catching her topless in the bathroom, he’d think that Emma would try to avoid him. Apparently he was wrong. Opening the message, a picture filled his screen. Emma stared back at him, smiling. In the bathroom. topless.

Noah stared at the picture. Only a few moments ago, he had been frustrated thinking he’d never see her body again. Now he had a picture on his phone of that very same body. The perfection of her breasts that he had recognized in an instant, but only an instant, was now on his screen, for him to admire. The size of apples and perfectly round, without even a hint of sagging. Her nipples, pink, and so hard that they seemed to be begging for Noah’s touch.

The obvious question should have been why Emma had sent him this selfie. But all capacity for rational thought had already left Noah’s mind as his blood rushed southward. As he stared at her tits, hypnotized by their beauty, his cock started straining against his pants.

Noah didn’t want to waste any time. He took off his clothes as fast as he could, tossing them aside. He laid down on his bed and opened the image again. He needed to look at those tits while he jerked off. The thought of his sister’s naked body made his cock even harder. He grabbed it with his right hand, giving it a firm stroke. He closed his eyes and imagined how it would be to touch Emma’s tits. He could almost feel their weight in his hands, her nipples between his fingers. His cock pulsed in his hand and a bead of pre-cum appeared at the tip.

He opened his eyes and looked at the picture again. The image of her naked breasts, now combined with the sensation of his own hands, made him even hornier. He began stroking his cock in a steady rhythm as he studied her selfie intensely. Then his phone buzzed, and on the top of his screen appeared a notification that Emma had sent him a new text.

“Don’t I get something too?”

Noah was stunned. Did his sister just ask for a picture from him? In his horny haze, Noah didn’t reflect on the unexpected request too much. The idea of taking a picture of his cock and sending it to her, actually seemed pretty hot. Thinking of Emma watching his big cock as he was watching her tits made him even hornier. Without further hesitation, he opened his camera and snapped a close up picture of his cock laying on his stomach, making sure he included his balls hanging between his legs. He added the picture to the text conversation and hit send.

Emma was laying on her bed, her jeans open. She was leasurely playing with her breast, softly rubbing her mound over her panties. She was horny, but stimulated herself just enough to keep her in this state of arousal. She was waiting for a response from Nathan, her boyfriend, to really lose herself in the moment. She knew he’d love the selfie she had sent earlier, as he always mentioned how much he loved her perky boobs.

When her phone finally buzzed, her smile disappeared when she saw it was a text from her brother. That was not what she needed. It reminded her of him barging in on her just as she was sending her photo to Nathan, threatening to kill her mood. She knew it wasn’t completely his fault he had walked in on her, she shouldn’t have forgotten to lock the door. But it was hard not to resent him at least a little for the shame she felt when thinking back to her brother seeing her boobs.

Regardless, she clicked open the text and her eyes widened. It was a photo of a giant, hard cock! Why did her brother send her that? Maybe it was meant for someone else, and Noah had mistakenly selected her number from his contacts?
