Vincent was coming to town for the weekend so I invited him to stay at my place. We only get to see each other a few times a year since he travels a lot for work. When he gets tired of the rat race and wants to let his hair down, I am his first call. Vincent's timing couldn't be more perfect.
Vincent is my big brother. He's two years older than me and ever since we were kids, we've dared each other to do pranks and stunts and other stupid things. Over time, we developed a magnetic animal attraction we could not deny and the dares were mixed with sexual favors. The dares and favors became more elaborate and sometimes even we would cringe just thinking them up. Vincent is my evil twin.
I called my friend Keli to let her know Vincent was in town. She cleared her schedule so she could be available for the weekend. I told her what I had planned for the dare and asked if she was interested. She gave me a big smile and said, "Bet. Text me when you're ready." I texted her Vincent's flight number and she would bring him here.
Keli is a professional driver and former Marine. At six feet tall, Keli is a tall, athletic, muscular girl; fit and toned like a real-life Warrior Princess. She's a blue-eyed brunette, just like my brother. She provides car service and security. It's comforting to know she is nearby when Vincent and I take one of our walks on the wild side. This time she would help me get my revenge.
We hadn't seen Vincent in a few months, so Keli stopped in to visit. I was so happy to see them both. They actually looked like they would make a good couple. We chatted for a while to get caught up until Keli had to go. That left time for me and Vincent to discuss the dare. Last time, it was Vincent's turn to dare. He took me to a motel next to the truck stop and sold my pussy to truckers all weekend. I had more cum shot into me in those three days than I had the rest of my life combined. This time it was my turn to dare. I figured that turn-about is fair play, so he would be my whore this time.
The standing deal between Vincent and I was that once you accepted the dare, you could not turn back. I will never forget the time he dared me to steal a cop car, 100% sure that I would not do it. He was wrong. We jumped in the car and I drove it like a NASCAR driver at the Daytona 500! What a rush! I drove it out to the woods where nobody would find it. We were on an adrenaline rush and when I stopped the car, I thought we would explode.
We jumped out laughing hysterically! We raced around to the front of the car where I leaped into Vincent's arms for a passionate kiss. We could no longer contain ourselves. Vincent put me down and bent me over the hood of the cop car, yanked my pants down and fucked my brains out. Oh, God, the adrenaline rush and Vincent's big dick pounding away at my wet slit brought me to a stunning climax! I laid forward on the hood of the car, my pants and panties pulled down around my ankles as my body convulsed in orgasm. It was incredible!
Vincent called somebody to pick us up and we were long gone when the cops found the car two days later. That remained our benchmark scene for years to come.
I had been working on this new dare since I swallowed the last load of truck driver cum three months ago. I was going to dare him to be my sissy bitch sex slave for the weekend. We ordered in and chatted away over some Chinese food. Our chat finally came around to the dare.
"Well, Sam. It's your turn." was all he said.
I stood up and walked around him, hands behind my back.
I said, "I dare you to be my submissive sex slave for the weekend. I will be your mistress and you will be my slave. You will comply with my every command or suffer my wrath. Do you accept the dare?"
I intentionally left out the word "sissy" so as not to tip him off. I was sure he figured he would spend the weekend kissing my feet and getting his ass paddled, but he couldn't be more wrong.
Vincent said, "Sure, sis. You're on. I will submit to you, my mistress, and become your slave."
"Pinky swear." I said and we shook pinkies, sealing the deal.
I texted Keli and told her we were on. She would get the room ready and pick us up later. Meanwhile, I would dress up my brother as a pathetic sissy and doll him up so he looked good enough to fuck.
"Slave!" I yelled, "Get your ass over here!"
He stood and walked over to stand in front of me.
"Eyes down, slave! You do not look your mistress in the eye. You will address me as mistress do you understand?" "Yes mistress" he said, eyes down.
"Good boy. Get undressed, slave, and make it snappy. Hurry!"
Vincent is a handsome man, tall with dark hair and blue eyes. He has a tall, fit body and a good-sized dick and I can't get enough of it. He stripped naked.
"On your knees, slave! Your most important reason for existing is to please your mistress and you can start right here."
He said, "Yes mistress."
I lifted the hem of my sundress with my right hand and grabbed his hair with my left.
I forced his face into my crotch and said. "Eat it slave!"
He reached around and grabbed my ass cheeks with both hands and held me in place while he ravaged me with his tongue. My brother was very skilled and he had me cumming in minutes.
"Oh! Vince! Fuck yes! Ohhh, yes, eat me! Uhh. Mmm. Oh! Oh! Vince! Mmm...oh...oh...oh."
I screamed and moaned as I orgasmed, creaming his face with girl juice. I held his face there, my body quivering, until my orgasm subsided.
I pulled him away from my cotch and said, "Well, slave, I suppose that will have to do. Now get your pathetic body in the shower and scrub it. Shave off all that nasty hair off while you're at it. All of it! Mistress will not take you out with that filthy hairy body. Your outfit is hanging in the closet. You will be dressed and sitting on a pillow on the bed when I come in there. You have one hour." I slapped him on the ass and yelled. "MOVE IT!"
"Yes, mistress" he said, and off he went.
Vincent wasn't sure what Sam had planned. She could dream up some bizarre shit, and she had an evil streak too, so he was a little apprehensive. He needed a quick shower anyway. Knowing Sam, he had better hurry or risk getting his ass paddled. He toweled off and looked in the closet. It was completely empty except for one single hanger with an outfit on it and a pair of black pumps on the floor. It was a black dress and crotchless black pantyhose. Vincent put on the clothes and they fit well, kind of comfortable, really. Even the shoes fit. His package was hanging out in plain sight for anyone to see. He sat on the pillow just as his sister walked in. Vincent's chin dropped. She was wearing a crotchless black leather teddy with fishnet bodysuit and platform boots. She had a long leather riding crop sticking up out of her left boot, and she was wearing make-up. Sam never wore make-up.
Vincent thought 'Holy shit! Look at little sister!'
I said, "Good boy, or should I say good girl? Sit here, bitch."
I pulled out a chair for him at the vanity, facing away from the mirror. "Well, if you're going to dress like a bitch, we need to pretty you up. Now let's see what we can do with that ugly face of yours."
I pulled his long hair back into a ponytail and looked at his face.
"Mmm-hmm. I see the problem right here. An ugly bitch like you needs lots of make-up. Sit still."
I really overdid his make-up and put on enough to make him look like a two-dollar whore. "There we go. Now you are REAL pretty. The guys are going to love you, bitch. Your new name is Sissy. You are my little bitch, Sissy." She kissed him on the lips and said, "Oopsie, I almost forgot the lipstick! Look here Sissy, look at me.", and she grabbed his face and held his chin. She got out a gaudy shade of Cocksucker Red and said, "Here we go, Sissy." And she painted his lips in a Joker-esque style. "Now that is MUCH better. That's a good color for you, bitch. Cocksucker Red." She brushed his long hair and turned the chair so he could see himself. "Now that you are a pretty bitch we can go to ladies night. Well, Sissy? What do you think?" Vincent looked in the mirror and Sissy looked back.
Vincent thought, 'Holy shit! What the fuck did I get myself into?
I said, "Well, Sissy? What do you think? Tell me!"
Sissy said, "Yes, mistress, I am very pretty. Thank you, mistress"
I said, "Well, what are sisters are for Sissy?"
I walked to the bed and said, "Come, Sissy. I have some accessories to go with your outfit."
I picked up a couple things from the dresser and put one around his neck -- a ball-gag, and another one on his head, a blindfold. I put my arms around his neck and looked into his eyes. I held his head and gave him a big kiss on his obscenely red lips, slipping my brother some tongue, lipstick transferring to my lips.
I said, "Just one more thing Sissy and we'll be ready to go. I put the ball-gag in big brother's mouth and slipped the blindfold in place, I sat down on the bed and reached under Sissy's dress to feel up her cock and balls.
"Mmm...Sissy. What a nice package you have! The boys are going to love this!"
Sissy's cock was hard as a rock and I was slowly stroking it up and down, up and down, over and over. I put my mouth over the head of my brother's cock and licked the underside of his head, getting lipstick all over it. He moaned against the ball-gag and exploded in my mouth. I caught most of it in my mouth and the rest dripped down my chin and down the front of my new teddy.
I yelled, "God-dammit, Sissy! Look at the mess you made all over my outfit!"
I stood up and grabbed Sissy around the throat and backed her up against the wall. Sissy landed against the wall with an, "Oommf!" and I continued berating her.
"I can see we are going to have to take special measures to make sure your pathetic, tiny dick doesn't go off again!"
I pulled the riding cop out of my boot and it made a loud "Slap!" as it landed squarely on his freshly shaven nut sack.
"Mmmmmphf!" shouted Sissy, still blindfolded, the ball-gag doing a fantastic job.
Vincent thought, 'Holy shit! Little sister isn't fucking around! She is punishing my sissy ass already and we haven't even left the house yet!' Just the thought made him cum again, he simply could not stop himself. He shot cum all over my outfit.
This time I pulled off the ball gag, grabbed him by the hair and said, "Lick it off, bitch! Lick your cum off your little sister!"
I dragged his mouth all over the front of my leather outfit making him lick up every drop. I was bitching the whole time but Sissy didn't hear it, she was in heaven being forced to lick up her own cum by her little sister, the closet psychopath, punisher of men. I was going to have fun with Sissy all weekend if it killed her.
