My Sister Annie Caught Me Peeping On Her

My sister Annie and I have both been working from home this summer. Annie has an internship where she can work from anywhere, and I've been doing a research project for one of my college professors that keeps me home and on the computer most days. Our parents both work in the city, so it's just the two of us at home during the day. We stop by and hang out with each other when we take breaks, and we usually eat lunch together.

Annie has always been hot, my friends often joke that she must have a different father than me. I just laugh it off, but I have to admit that she looks good, even to me, her younger brother. Annie likes to wear panties and a tank top when she works at home. She usually skips the bra, and she looks amazing. Her breasts fill out the tank tops nicely. Watching them swing as she walks is mesmerizing.

I stopped by her room on one of my breaks. She sat on her bed, working on her computer. She was leaning forward, and I got a nice look down her shirt. Annie has curly brown hair, an insanely cute face, and dark tanned skin. Her breasts are perky and really just perfect, and as I peered down her shirt, I could just see the tops of her reddish-brown nipples. Fucking awesome.

"Look at these cute tank tops, I have to try them all on!" she said excitedly as she ripped into packages that showed up at our door this morning. She showed me a couple. I wanted to see all of them on her, most with thin fabric, and some were fairly low cut.

"You'll have to show me the best ones," I said. I tried to sound nonchalant.

"Yeah, I'll wear the best one at lunch." She paused a moment, "Hey, I'd better get back to work now, see you later."

I left her room and went back to mine. I had a lot of work to keep me busy, so I got to it. I was in the zone coding for most of the morning, and I was surprised to look up and see it was nearly lunch time. I headed out of my room to see what we might have in the kitchen. On the way, I went by Annie's room, her door was partially open, and she stood in front of her mirror admiring herself in one of her new tank tops. She looked hot, I mean, really hot.

I stood outside her doorway watching her, the outline of her breasts through the thin tank top was incredible. It was almost a shock when she whipped the shirt off over her head. Her perky breasts popped out. She walked back over to her bed topless, and she picked up the pile of shirts and looked at them. She held one up, then the other. Her breasts had me completely hypnotized. I looked down at my shorts; my cock was hard, pushing up against the fabric and straining to get out.

She pulled on a white tank top, stood in front of her mirror, and started to dance. Her breasts jiggled in the tank top as she danced and then spun around. She smiled at herself in the mirror. She looked so beautiful and sexy. I couldn't help myself, I reached down and put my hand on my cock. I started to slowly stroke my cock. It seemed like time stopped. I imagined burying my face between those breasts.

Then she pulled her tank top off over her head. My eyes widened, what a perfect set of tits. She looked in the mirror and cupped her breasts in her hands, then she started to dance around the room again, this time topless. She was stunning, she swayed gently as I stared at her from behind her door. But then she stopped suddenly.

"Matt, what the fuck are you doing?"

Holy shit, it didn't occur to me that she might see me as she moved around the room. I'm in trouble.

"Uh, I was just walking by on my way to the kitchen. I saw you dancing, and I didn't want to interrupt," I answered quickly.

She looked at my hand in my shorts. Fuck, I forgot about that.

"No, I heard you walking by a minute ago. It's pretty obvious that you've been watching me. You fucking pig." She walked towards me, and she stopped right in front of me.

"You shouldn't have done that!" she said angrily.

As she spoke, her foot blasted up between my legs. I had no idea it was coming, and she fucking nailed my balls. I tried to breathe, but couldn't get any air. I looked at her, and I felt my legs give out from underneath me. I crumpled to the floor in agony.

"You fucker!" she said.

I lay on my back in struggling to breathe. My legs must have been far enough apart for her to get her foot between them. She nailed me again.

"OOOOOF!" I moaned.

"And you still have a fucking hard on!" she said as she kicked me again.

I managed to get both hands on my balls. I curled up and covered up.

"Stop, Annie, stop!" I moaned. She stood over me, looking down in anger.

"No, Matt, we're not done yet, GET UP!"

I couldn't do it. I managed to roll onto my hands and knees, but I was still curled up, and I was still protecting my balls in case she decided to blast me again.

"GET UP NOW!"

"I'm trying." My knees were shaking, so I held onto the door and pulled myself up. She was still topless, and even in agony, I had to admire her breasts. Just fucking perfect.

She caught me looking, "You have the balls to stare at my tits still?" she said, looking at me derisively. "Fucking pervert."

I was afraid she would kick me again. I held my cock and balls with one hand, the other was on the door helping me stand.

"You've seen my tits, take off your shorts, Matt."

I didn't move, I just looked at her, confused.

"Do it now, or you'll get kicked again."

"Okay," I groaned. I didn't know what else to do, she was in charge now. I pulled my shorts down, and my cock popped up as I pulled them down. She looked at my erection, my hand covered my balls, and my cock pointed at her.

"I just can't fucking believe you, standing there with an erection while you peep on your sister." I did my best to stand up straight, but it wasn't easy.

"You look amazing, Annie. I'm sorry I was watching you, but you are really beautiful." I wasn't just trying to calm her down, it was all true. I managed to stand up straight, and I tried to hold on to some shred of dignity.

"That's nice, Matt, but this is not acceptable." Before I could even move, her foot shot up into my balls again.

"FUCK!" I cried out as I dropped to the floor again. She slammed the door on me and went back into her room. I lay on the floor outside her door for a few minutes just trying to recover, then I made my way down the hall to the bathroom. I pretty much crawled into the bathroom, I locked the door, and put on the light so I could check my balls. I sat on the edge of the toilet and felt around them, they seemed to still be intact, but they were sore as fuck. My cock was still hard. Really hard. For some reason, getting kicked in the balls had me really excited.

I couldn't help myself. After I finished checking my balls, I took my cock in my hand and squeezed it. I moaned quietly, I was so close to cumming. The pain in my balls mixed with the pleasure of my hand on my cock. My mind was filled with the image of Annie naked, dancing around her room, her breasts swinging. I couldn't get the image out of my head. I didn't want to jerk off, but I was already so far down that path that there was no turning around. I spun around and pointed my cock into the toilet. In just a few strokes, my cock erupted, and I blasted cum into the toilet.

"OH FUCK!" I moaned, much louder than I wanted to. I hoped Annie didn't hear me, but it felt so fucking good. "OHHHHHH! FUCK!" More and more cum splashing into the toilet, it was getting ridiculous. I thought I might fill the toilet. What an incredible orgasm, what the fuck was going on? It seemed like my brain had short-circuited.

I sat in the bathroom for a long time after I finished cumming. I was scared to leave. I heard Annie head downstairs for lunch, so I slinked back to my room. I lay on my bed with my aching balls, and I just hid out for the rest of the afternoon.

Annie came by my room in the late afternoon, and she brought me a banana to eat.

"You haven't left your room all afternoon. Are you okay?"

"I'm okay, I just have sore balls."

"Um, about that, sorry I got so mad, I shouldn't have kicked your balls so hard."

"It's okay, I deserved it," I admitted. "I just hope we can get back to being buddies again."

"We are, to be honest, you just surprised me, and I lost my temper," she said. "Besides, who could blame you? I have really great tits." She smiled at me, then walked out of my room.

She was right, she really does have great tits.
