Big Sister Is Watching You/Chapter One

Chapter One

It was around 12 AM on a summer night. Iris was lying on her side in her bed, scrolling through whatever apps sixteen-year-old girls find entertaining. She wasn’t wearing anything but panties and a T-shirt. She didn’t have any school in the coming months because it was summer, so she stayed up as late as she wanted every night. No summer job either. She didn’t want one yet. Her parents didn’t mind because she got good grades.

After scrolling for a while, Iris felt she needed to pee. She hesitantly got up and quietly left the room, being slow because her parents and brother, Jacob, were asleep. To make it to the bathroom she had to pass by Jacob’s door, which she noticed was slightly open. She decided it would be in her interest to take a peek inside. It was dark in the hallway, so he couldn’t look back at her if he was awake.

She was shocked to see her innocent and cute nine-year-old brother masturbating under his sheets while watching something on his phone. Her eyes widened in surprise and she almost gasped, but she knew she had to stay silent. Well, he was a boy after all. Boys do this type of thing. She shouldn’t be so quick to judge. He’s exploring himself like she did when she was his age.

She kept watching and felt more immersed in it. It was almost cute how her little brother made those expressions and how his hand moved under his blanket. Her mind drifted and she imagined what his cock looks like by now, what he was watching on that phone, and she got aroused. She’d seen him naked before, but only when they were younger. She got so caught up in her thought that she forgot why she left her room. Suddenly, she snapped out of it and scolded herself for thinking like that, and she rushed to the bathroom with the caution of making noise.

She closed the bathroom door behind her slowly and flicked the light on. She slid her panties off and noticed a wet spot on them. Did she get horny from seeing that? She sat on the toilet seat and thought to herself while she peed. This wasn’t right. She couldn’t be aroused by her brother, much less with that age gap! But she also thought that it wouldn’t hurt to observe. She felt tempted to look again and watch until he orgasmed.

Iris finished peeing and quickly wiped herself. She turned the light off before she opened the door, then quietly left. She slowly made it down the hallway and peeked back into Jacob’s room. He was still masturbating. She felt her face get hot as she watched him stroke his cock at a moderate pace. It seemed his cock wasn’t very big yet observing his hand movement.

Her heart rate was through the roof. Her adrenaline was coursing through her entire body, and she loved it. The thrill of watching her brother masturbate was unlike anything she’d ever felt before. She was so caught up in the moment that she reached her hand into her panties and began to feel around her pussy. It was incredibly moist. She could slide her fingers in with no force at all. Her clit was hard too, and touching it sent electricity through her entire body. She was so captivated by him that she had to masturbate. She had to do it with her little brother. She slid her middle finger into her slit and moved it at the same pace he stroked. She pretended he was fucking her because that was all she could think about. She could barely control herself, her moans were nearly slipping out. She managed to hold them in, but god, it felt amazing. Watching her little brother was better than the porn she normally watched. She knew it was wrong but it felt so right.

She began approaching her orgasm and she had to use her offhand to keep herself silent. She noticed he was starting to speed up and she knew he was close as well. She was going to time her orgasm with his. She watched closely as he slowly raised his hips. He closed his eyes really tight and clenched his teeth, about to cum. She was there too, right on the very edge. She quickened the pace and closed her eyes with him and they got closer and closer, then they came. They came together, except only one knew. Iris’ orgasm was mindblowing. She could barely process it. She managed to keep quiet thanks to her offhand, but if she could have made noise, it would have been loud.

Iris opened her eyes again and looked back inside Jacob’s room. She could see him breathing hard, just as she was. So cute. A little boy who just came and is recovering. She looked down at her panties. What a mess, this is probably the wettest her panties have ever been. She’ll have to change them. She took one last good look into Jacob’s room. He’d turned off his phone, so she couldn’t see anything anymore. She decided to retreat back into her room and slowly close the door.
