**************
My eyes scan the room as I search for my younger sister, Katherine. Maybe she was in her room, all curled up in her blanket. I can't help but make my way towards her room. The house was empty since mom dad were gone on a vacation for a week. Katherine's responsibility was now on me since I was the elder one from the both of us. But... I can't take her responsibility when she needs to keep herself safe from me.
I've been having some crazy lustful thoughts about Kathy since she turned 18 two years back. For two years I've been trying to resist her body. For two years my cock painfully and silently pulses whenever she enters a room. I had to stop myself from staring at those beautiful and perky B-cup breasts. Her long brown hair wants me to bury my hand in it while I fuck her from behind. Her petite body makes me wonder what she would look like when she's lying under me.
I do love her a lot. She's my younger sister and I am very protective over her. And sometimes possessive too. I haven't let any guy near her because I feel like she belongs to me and only me. I know this feeling is wrong and I'm her elder brother by two years. And I should be the one to protect her but... I can't help it. No matter how much I try to ignore this lust but it just won't go away.
I sigh as I stop in front of her room. My cock painfully pulsing against the zipper.
I knock on the door. ''Kathy?''
No response.
I knock again and wait for her to say something but again there was no response. I open the door and find her peacefully sleeping in her bed. I chuckle as I find her covers lying on the floor. It was still 7 pm in evening and she was already asleep. A smile touched my lips as I stare at her sleeping form in a non creepy way. But then...I noticed what she was wearing. She was wearing a black lace satin dress which stopped right near her inner thighs. I gulp down the lump in my throat as I felt the dryness in my throat.
She was looking so fucking beautiful with all her hair sprawled on the pillow. And the way she was sleeping gave me a small peek of that sexy black thong which covered her pussy. I close my eyes and take a deep breath.
Fuck. I want to touch her, taste her, fuck her and make her cum again and again until we both get tired of it. This is so fucking wrong but I can't help it. I open my eyes and they fall directly on those breats. Her round and firm looking breasts rising up and down as she peacefully sleeps. I clench my fist and turn to walk out from her room before I do something I'll regret. But I immediately stop as I hear a sound coming from her sleeping form. Not just any sound. It was a moan.
She was fucking moaning in her sleep.
My cock hardened even further listening to her precious moan. Fuck fuck fuck. I can't help it.
She stirs in her sleep and lies on her back, completely open to me. Her thong covered her pussy tightly and I could see the shape of those perfect vertical lips. To my shock, her hand goes down towards her pussy and she starts to rub it.
She was fucking having a sex dream.
I walk towards her bed and without thinking twice, lie down on the bed beside her. Her eyes closed and those perfect rosy pink lips call me towards them. My eyes cast down towards her breast and I can see her nipple trying to peek out from the dress. This dress is totally testing my patience. Kathy moans again and I knew that I can't resist anymore. Trying not to wake her up I reach for her dress and remove the strips of the dress from her shoulder. My eyes concentrate on her soft looking breasts as I lower her dress further to uncover them. Kathy doesn't move when I do so.
My mouth immediately waters at the sight of those perfect breasts. Without thinking further more, I take her breast in my hand and hold it firmly in my hand. Fuck... it was soft and just... perfect. My imagination was running wild by now. The nipples hardened under my touch and I continued to play with it. Pinching it, rolling it, pulling it.
Kathy moans loudly and I immediately stop. I don't want to wake her up but I don't want the fun to stop too.
Thankfully she let's out a sigh and then goes back to sleep. I continue to play with her nipples. I knew I was taking a huge risk as I get more close to her but it was worth it. I pull myself up a little and take her breast into my mouth. I moan as I make circles around her hard nipple. I take it between my teeth giving it a soft bite. I hear Kathy moan again but this time it felt a bit real and not like she was doing it in her sleep. My hand went down towards her pussy and I could feel the heat of it on my hand. I look at her face as she moans and then suprisingly, I feel her hand going into my hair and pressing me towards her breast. I groan and don't giving my attention to it.
My hand rubbed her panty covered pussy, slowly and teasingly. Kathy bites her lip and I knew that she has fallen in the ocean of lust. I push the thong aside and rub her pussy lips. She was already fucking wet. I remove her breast from my mouth and lift my head to look at her face. I continued to touch her pussy and rub her clit slowly. Her eyes pop open and her mouth falls open and her breathing increases. She didn't stop me and I didn't intend to stop myself. Her eyes closes and she let's out a moan as I push a finger inside her. I add another finger and pull it in and out of her pussy. While doing so, I continued to rub her clit and she lifted her hips off from the bed.
''Please, Jake,'' she whimpers.
I raise an eyebrow in question. ''Please what?''
''Please make me cum,'' she begged.
''Aren't you a horny little thing. A dirty little whore who wants to make herself cum on her brother's fingers,'' I teased.
I don't know from where all those dirty words came out. Maybe it was the frustration that had been hidden deep inside me with the painful fact that I can't have her. But now... that would change.
I fingered her faster and faster with her rapid breathing. Her pussy clenched around my fingers and I knew that she was close.
''You want me to cum?'' I asked.
Kathy nods rapidly.
''Then cum you dirty whore,'' I shouted and Kathy immediately came on my fingers.
I remove my fingers from inside her and look at my now wet hand. The smell of her cum was so fucking magical. I look at her right in the eye as I lick that magic off from my fingers.
**************
We stare at each other as we sat on the dinner table opposite to each other. The silence surrounded us but then my sister spoke up.
"You fingered me," Kathy stated in an accusing tone.
I give her a shrug. "You liked it."
Kathy narrows her eyes at me and gives me a sharp glare.
"Why did you do it?"
"You were moaning in your sleep and were touching yourself," I pointed out.
Kathy's eyes widen at the revelation. "Wha-what?"
I give her a shrug again. "I wasn't able to resist you."
"But you are my brother, Jake," she said in a alarming tone.
"You didn't give a fuck about it when you came on my fingers."
Kathy looked baffled and shocked.
