My twin brother Brian thinks I'm the biggest bitch in the world. I'm inclined to agree with him. My name is Kat (actually Caitlyn but fuck that shitty name) and I love messing with him. We're both 18 and still living at home so I have lots of opportunities to wind him up. If Mom asks him to clean the bathroom, I'll wait for him to finish and then bring trash from my room and refill the trash can. If he goes a month without getting a whipping, then I haven't done my job.
It's really all his fault. He's such a floor mat, it's my job to try and toughen him up. If I put my vegetables on his plat, he'll complain but he's never tried putting them back. Lately he's been making it so easy for me. Brian always was girl crazy but lately he's been getting worse. I've even caught him drooling over a fucking exercise commercial.
So, to tease him, I've been wearing skimpier and skimpier clothing. I'm thin without a lot of curves so I have to practically be naked for people to realize I'm female. I started wearing my hair in pigtails to confuse him further and make him think of me as a girl. But I also started wearing skirts and thongs to remind him I'm a totally fuckable woman... if he wasn't my brother.
I eventually had an idea for a masterpiece of humiliation. I'd 'accidentally' send him a topless shot from my phone. I know him, the first thing Brian would do is run to the bathroom and jerk off. I'd stand right in front of the door and wait for him to finish. I couldn't wait to see his face in a mixture of surprise and embarrassment. After telling him I know he busted a nut to his sister, I'd have ammunition for years to get him to do my chores and shit.
I waited for a day when Dad was at work and Mom was out shopping. Brian was sitting on the couch watching TV so I ran up to the room and quickly disrobed. I pulled my thong just low enough for him to know my pussy was shaved. One arm held my phone while the other grabbed a nipple and pulled it hard. My other nipple instantly became diamond hard too. Before taking the picture, I took a second to admire my body. My breasts were b-cups with cute little areolas and small nips. I kissed the air and thought how I'd fuck me as I took the picture.
I sent the picture to Brian and quickly got dressed. I went to the railing and screamed out, "I ACCIDENTALLY SENT YOU A MESSAGE! It was meant for Brad! Don't look at it, just DELETE IT!" Brad didn't exist. There wasn't anyone I knew who I could stand or would be able to stand me. I then went back to my room and slammed the door shut so he'd know I where I was. I listened at the door and, sure enough, I heard Brian run towards his room. Geez, he could at least try to be subtle about what he's up to. I gave him a second after I heard his door close. Then I slowly turned my door knob.
Before I could open it, I heard Brian coming out of his room. Shit, what's he up to? He quickly entered the upstairs bathroom. I knew he liked to jack off in there too but why'd he go to his room first? I waited a bit longer in case he had any more surprises for me but he remained in the bathroom. Curious, I grabbed a makeup mirror and left my room quietly.
I listened at the door but couldn't hear much. So I slowly dropped to the floor and used the mirror to see just what he was up to. To my surprise, Brian was completely naked. It had been awhile since I'd seen him without clothes on. He was always so self-conscious that he never took his shirt off when we went to the pool or beach. He did have some hair in weird spots but nothing I'd call ugly. He even had a six pack and his chest muscles were nicely defined. Of course, the first thing I noticed was his nine inch cock in his hand.
He had it wrapped up in a condom! That's why he went to his bedroom. By why didn't he just jack off in his bedroom? I didn't have time to think about it, I was too busy thinking to myself, "Yes, Brian, fuck yourself. Fuck you, Brian." His other hand held his phone and I knew I'd have him by the balls when he got out. The thought that he was seeing me naked made me hotter than I would have guessed.
I reached down and rubbed my clit through my panties. My nipples were hard again but I needed my other hand to hold the mirror. Brian jerked faster and faster and suddenly I was desperate to see him cum. "Fuck you, fucking Brian. You incest loving fucker." I rubbed myself faster too but Brian came before I had the chance to. "FUCK! You shitty bitch piece of shit!" Still, I was amazed to see just how much he filled that condom. It was like seeing a balloon animal being blown up. Suddenly I realized why he was naked, using condoms, and why he wasn't jacking it in his room. I wondered how many messes he cried over in his room, hoping no one would notice.
Brian carefully took off the condom, making sure to not spill a drop, and tied the end into a knot. He put the condom in the trash can and covered it with toilet paper. I got up, grabbed my mirror, and went back to my room. My great plan was forgotten in favor of a new one. I waited for him to leave the bathroom before leaving my room and calling out, "I'M GONNA TAKE A SHOWER SHITHEAD!"
I entered the bathroom and locked the door. I turned on the water and undressed before looking into the trashcan. I retrieved the condom and was amazed. In my hands, the condom was hot and heavy. There was SO much cum! I wondered if Brian had just bought the condoms just for jerking off. Maybe my brother was actually getting some.
I'd never admit to him that I was a virgin myself. I got such a kick out of being the intimidating megabitch at school that I scared all the boys away. Those fucking fuckers didn't bother me anyways. I doubted anyone could please me like I could please myself. I took the condom and washed it carefully. I didn't want it to break accidentally.
