Kim Vampire Vampire_Lamia@yahoo.co.uk My sister tucks me in. One evening, my mom had to go visit someone. So, she told me to stay home and look after my younger sister Kim. I reluctantly agreed to stay home as I already had plans. Mom left at 8 in the evening, giving specific instructions that Kim was to go to bed at 10. After she had gone, I went to the living room. Kim was watching TV. I also sat next to her on the couch. "You've to be bed by 10, Kim." I told her in a teasing manner. "Well! Is it 10?" "No." "Then stop bugging me now." She said dismissing me. After an hour, she turned towards me. "Say Mark. Why don't we rent a movie or something?" "As you wish. Just make sure it winds up before 10." I replied. She ran out and returned back within 5 minutes with a VCD from the nearby Video store. The name of the movie was Double Blast. It was a silly movie about a young girl thrashing some guys in a scene. I went to my room as I had an assignment to complete.Some time later, I noticed the time and saw that it was 10:10. I returned to the living room. Kim sat there watching TV. "Hey, Its well past 10. Go to bed." I told her. Now, Kim was 12 and since I was 5 years older than her. But she rarely listened to me. But today I had been delegated the authority to order her to bed. Kim was leaning back on the couch with her jacket lying next to her. Her arms were above her head. I could see the tiny tufts in her armpits trailing up towards her slim arms. "I'll go to bed in a few minutes." "No, you'll go now." I said gripping her bare arms and pulling her up from the couch. As I tried to raise her up, I couldn't help admiring the hardness in her arm. They were certainly harder than mine. And as she tried to free her arm, the movement caused her biceps to flex incredibly. She was a slim girl but her arms seemed really powerful. As I pulled her, I was embarrased to find that still she was in that half-reclining position and was countering my strength easily. Suddenly, she pulled with amazing strength. She was still sitting on the couch, and the force at which she had pulled me resulted in my losing balance. I fell on her lap. And not only were her arms hard, even the rest of her body was harder than mine. As I lay there on her lap, pondering over the strength and firmness of her thighs, I couldn't help but notice the muscularity on her lean and firm body. She laughed out loud at my weakness. "O my God Mark! You are so soft." She said gripping my arms. Her fingers clasped tightly around my biceps, which were squished by her power. "Oww" I cried out." Meanwhile, Kim was enjoying this immensely. I writhed intensely and fell off her lap. She stood up. "Hey Mark. You are such a wimp." "Shut up, you bitch." I roared and leapt at her. She moved to her left quickly and I fell face first on the couch. I jumped up and was quick to stand up, facing her eye-to-eye. I towered over her 5'3'' body. I was 5-9 and 180. Kim might have weighed 110 then. So, we clasped hands in traditional wrestling style, both trying to subdue the other. Her small yet hard hands were becoming too much for me to handle, as I realised that my strength was fading away. Pretty soon, she had brought me to my knees. "Now wimpy boy! Look what I've done to you. You're such a weakling." "Owww."I cried in pain as she increased the pressure on my hands. "Let me go, please." She let go of me. I sat there rubbing my sore wrists. "It seems now, that it is you who needs to go to bed, bro." She said grinning wickedly. She bend towards me and caught my left arm with her right hand and jerked me up to my feet. Then she swooped me in her arms in a cradle hold. "Looks like you could relish a sleep." I was too fucking scared to say anything. She carried me to my room with remarkable ease. She dumped me on my bed, and tucked me in. "Goodnight, dear brother. Sleep well." She said lowering down to kiss my cheek. Then she turned off the light and left the room closing the door behind her.
