"I need you to rape me."
I hadn't seen my sister all summer. She'd been away at an internship not even coming back for weekends. We'd always been close as brother and sister and her first words to me after 3 months came as a complete surprise.
I just stared back at her, willing her to explain, speechless. She started talking like an ape, dumbing it down for me.
"You guy," she said pointing at me. "Me girl. You penis. My vagina."
"Rape?" I asked.
"It's one of my fantasies, Cale."
Krista had always been straightforward. Cut to the chase since nothing else mattered right? Even at 20 she had blurted out whatever she wanted.
She sighed exasperated.
"Look, I've been sexless for the past three months, hearing from all my other friends back at home how they've been hooking up again with their past flings. I haven't had time to go out and date and you're the only guy I trust this intimately. To actually respect my safe word and still fulfill my fantasy."
"Okay, but you're my sister," I responded weakly.
"And you've always wanted to fuck me too."
At 5'11", Krista was a bombshell. At least I thought so. Her long legs, cute glasses, perky butt and small chest were exactly my type. She thought she had lanky legs and was flat as hell. And that her height cut her dating pool way down. She was also pretty much a stereotypical nerd which is why I was a little confused by her fantasy.
"Look, you're a year older than me, 6'3", cute, short black hair, nice body, and you probably have a really nice cock too. You're exactly my type, who cares if you're my brother. I'm just trying to play out this fantasy of mine, not date or start a family. I'm on the pill too so you can cum in me too."
My cock grew hard at her last sentence. My eyes traveled up her legs, reaching her shorts, the tiniest hint of her blue panties peeking out. Looking higher up, a white camisole, nipples poking out. And finally a smiling face, too cute and her blue eyes staring into mine.
She handed me a piece of paper.
"Here's a list of my kinks. Safe word at the bottom. Just come into my room tonight and do what you want. The kinks are just a guide."
I kept looking at her like she was crazy, although my dick had a mind of its own.
"Isn't this what all guys want? No strings attached sex with permission to be rough, and you can even cum inside?"
"Krista, I'm not even sure wha-"
She put her hand on my cock and kept staring into my eyes and just like that, I was convinced. Fine. If that's what she wanted.
"I'll wait till you're asleep," I said.
---------
I crept into her room at 2 am making sure she was asleep. I closed and locked the door, putting a rolled up blanket on the ground in front of it. I was in a suit, something that was requested on the kink list and I crept over to her bed. I could see her asleep on top of the covers, wearing an oversized shirt, unable to see what she had on underneath. I threw a small blanket on top of her face, obscuring her view, and put my hand over her mouth.
"Do not move," I said in a slightly deeper voice. "I'm going to release my hand over your mouth, but if you make any noise, this will be a lot worse for you. Nod if you understand."
She nodded. I released my hand over her mouth and went to blindfold her. I took one out of my pocket and tied it tight around her head. I reached my hand back to double check and make sure it was tied tight and wouldn't fall off, especially through what I was about to do to her.
"Who are you, what do you want?" She hissed.
I had to admit, her acting was pretty good. I struck her across the face. Another action approved on the list.
"Shut up, I ask the questions here."
She whimpered. I went on to tie her hands and feet together with a couple shirts she conveniently had laying around.
"Please," she said.
I stuffed a pair of panties on her nightstand into her mouth.
"You betrayed the boss, now it's time to pay the price."
Man, my sister had some weird fantasies. I lifted up her shirt, a black thong coming into view. I lifted it more showing her tanned stomach until it finally reached over her tits. My first look at her boobs, only a small handful but her pink nipples were cute and looked painfully hard. I reached up and groped her right tit. She tried to say something, her voice muffled by her panties so I took them out.
"Please sir, not this. I promise to do anything else."
"It's too late," I said, reaching out to pinch her other nipple.
I leaned over and gave them a quick suck and bite, a moan releasing from her lips.
"Besides, I know you're enjoying this, your body doesn't lie."
I cringed a little when I said this, the stereotypical rape fantasy line. Dedicated to the act, I reached down and put my hand over her panty covered pussy. I pulled it aside and slid a finger up her slit. It came out completely drenched in her juices. I took my finger and forced it into her mouth. She immediately sucked it off.
"This won't do," I said as I grabbed onto her shirt. I grabbed at the collar and tried to rip it off her. It was an old and faded shirt so I was able to make a tear and from there it was easy to do the rest. I threw the torn shirt to the side, getting my first unobstructed view of my sister in panties. The moonlight streamed into the window, almost like a spotlight.
I spent some more time with her tits, sucking them and occasionally slapping them. I tried my best to call her a worthless whore and other degrading terms, spurred on by her enjoyment. I could tell she was getting off and decided to continue on, ripping off her panties the same way.
I slowly ran my fingers around her slit again, this time focusing on her clit. Before long with some pretty hard rubbing on her clit, I could feel her body shudder and her orgasm wash over her. I could tell she was very turned on since it didn't take long for her to cum. I could also see she was trying her best not to moan too loudly, but one slipped out and I immediately slapped her boob.
"Oh my, you've already came but I haven't even taken my suit off yet. That seems kind of unfair."
I untied her arms and placed them on my chest.
"Undress me. Don't get any funny ideas though."
I allowed her to take my jacket off, but when she was loosening my tie, she tried to tighten it as hard as she could. Ready for this, I quickly threw her onto the bed, face down.
"Oh now you're in big trouble young lady."
I gave her a spank. Two spanks. Her cheeks reddening and her moans growing louder. I alternated between sticking two fingers into her and spanking. Each rotation bringing her closer and closer to orgasm. I grabbed her vibrator that was so conveniently placed on the foot of her bed and placed it on the highest setting as per her instructions. I flipped her over and placed it on her clit, lowering my lips to hers. I could feel her moan as we kissed, another orgasm wracking her body. Her lips were impossibly soft, faintly tasting like cherry chapstick. I let her rest a little and took a towel to clean up the damp spots on her bed. Then I leaned down with my tongue, lapping up Krista's juices, her hands pushing me away from her sensitive pussy.
I finally had to release my rock hard cock. I stripped quickly and straddled Krista laying on the bed.
"Open wide," I said, waiting a second for her obedience before shoving my cock into her mouth. She reacted as my cock only a little ways in, hit the back of her mouth, coughing.
"Too big," she whispered.
