Siblings Who Lust With Trust

Jack said, “Wow.”

The girls nodded.

Kimberly's Request Louis Kahn Nin

I never thought I would have sex with my little sister.

Never even had thoughts about it. Kimberly is a beautiful 10 year old, but she is my sister, and she's 10 years younger than me. Which makes it kind of humiliating that she trapped me. It happened one weekend while our parents were out of town.

I was coming for a visit that weekend, but the parents had to leave on business, so I said I'd watch Kimberly.

The first night there we watched movies and had dinner. Not long after dinner, Kimberly went to her room and I watched one more movie. After it was over, I went to inflate my air mattress in the guest bedroom. As I walked down the hall, I heard a rather load moan. I just took it as some show Kimberly was watching.

The very next thing I heard was a definite, “Fuck me harder.”

I approached Kimberly's room and opened the door. There she was, calmly sitting on her bed watching a porno. I turned her TV off and sat down next to her.

“What are you doing watching this?” I asked.

“I'm just curious about sex,” she replied.

“Kimberly, take some advice from me. I can be honest with you because I'm not your parent. I first had sex when I was 11. I wish I would have waited. I won't tell you don't have sex, because I have no room to talk. When you decide to, make sure it is with someone who will always be around, not some boy who will disappear months, weeks, or even hours later. Cause if you don't, you'll regret it just like me.”

“Don't worry, I know better.”

“Be sure that you do. I knew better, but I cracked. I had to learn from that. Don't do the same, learn from me. Now go put that movie back where you found it.”

The next morning I rolled over and was surprised to see a head with shoulder length brown hair laying on my pillow and sparkling blue eyes staring at me.

“Kimberly, what are you doing?” I asked.

“Just trying to wake you up,” she replied.

With that she reached out a started to tickle me. Her thigh brushed up against my crotch. It was at that point I realized I had a morning hard-on, and I sleep without anything on. I panicked. I didn't want her to noticed my protruding member so I rolled her onto her other side so her back was to me.

I noticed she wore no shirt. I froze for a second. It was enough time for Kimberly to push her hips back against me, and when she did my hard cock slid right between her ass cheeks and the tip just barely penetrated her asshole. Right away I knew she had this planned because her ass was lubed.

I went to push her away, but she reached behind, locked her arms behind my neck, wrapped her legs around my right leg, and locked in tight.

“No, no!” she pleaded. “Please don't!”

“But Kimberly, we can't do this.”

“Please, don't. I want to do this. Remember what you said last night. I want to give you this gift because I love you and you'll always be in my life no matter what.”

“Kimberly, we can't.”

“Who says we can't. We love each other. Besides, you're already in me.”

“All right,” I gave in.

I rolled Kimberly onto her stomach and straddled her small firm ass. I took a moment to stare at this lovely little person, her silky legs, smooth skin, and great smell. I looked at my hard-on, just barely pressing into her pink asshole. The tip was just halfway in her wrinkled orifice. I pushed forward gently with no progress.

It was like trying to shove my rod into someone's balled up fist. I grabbed Kimberly's tiny, soft butt cheeks and spread them. I pushed forward again. For a second I still had no progress, but then the head popped in and disappeared. Kimberly jumped a little. Her asshole was stretched to the point where every single wrinkle was ironed flat.

“More,” Kimberly requested.

I inched in further and paused. I could feel Kimberly's pulse beat on my cock. I can't even begin to describe the feeling. I furthered into her ass centimeters at a time, the walls of her anus pushed against my pole as if trying to push it out. Soon I was almost balls deep into my baby sister's willing asshole. I paused to enjoy the sight of my cock maxing-out the elasticity of Kimberly's rear cavity.

“How does that feel?” I asked Kimberly, tauntingly.

“Great. I can feel every inch of skin on your thingy.”

“Did it hurt?”

“Not really. It hurts at first, then it fades and starts feeling good. I have chills.”

“Want the last remaining inch?”

Kimberly answered me by lifting her hips causing her sphincter to swallow the rest of my shaft. Kimberly moaned as she relaxed back into the air mattress. I leaned forward so my chest was weighing into her back. I locked my arms around her collar bone, supporting most of my weight on my elbows.

I started pumping my cock in and out of her near impenetrable outlet, only drawing back an inch to an inch-and-a-half. I drew back and slid forward with the same deliberately calm pace as I did entering her. I put my face right next to Kimberly's. She lay almost with her face buried in the pillow, only her chin supported her head. Her mouth hung open as she pleasurably whimpered with each action of my rig.

“Kimberly you feel so good.” I whispered into her ear.

“I have a weird feeling in my legs and stomach,” she managed to say.

“Just let it go, don't fight any feelings.”

I kissed her soft sweaty cheek and gently kissed down to her neck. This seemed to fire her up more. Kimberly started to buck her hips. I decided to pull out more. I pulled back until the ring of her ass compressed the halfway point of my shaft. I ceased to make a mental note of how far to advance into her, then proceeded back out further so just the knob was in. I continued fucking her ass this time moving slightly faster, not passing the halfway mark. I scraped my teeth along Kimberly's neck, softly biting her, yet being careful not to leave any marks.

“Fuck my ass,” Kimberly told me.

I stopped teasing her neck. “You learn this from our parents' movies?”

“Yes” Kimberly puffed between breaths. “I wanted to to try it in my asshole before I decide if…I want it in my cunt.”

“What else did you learn?”

“Talking dirty.”

“Try it,” I encouraged.

“Only if you…if you play with…my neck…again.”

I did as instructed while diving in and out of her vigorously grasping butthole. Kimberly took a while to get some heavy panting moans out.

“It feels so good, your hard throbbing penis into my ass, fucking it so lovingly.”

I thought it was pretty good. She'd been studying hard. I rewarded her by dipping another inch further. I would continue to increase the stroke size and speed every few sentences to see how long she could continue.

“I can't believe how hard you are. Stretching out the sides of my butthole, pushing right through the muscles.”
