My step-sister is so dumb

Natalie flashed her little bald pussy and it turned me on, so I took her upstairs and tricked her in to letting me fuck her.

When I was 12 I tricked my incredibly dumb and stupid 7 year old step-sister Natalie in to letting me fuck her.

We were at home alone and both a little bored, we spent most of the morning downstairs watching TV in our pyjamas, Natalie was wearing a nighty and sitting on the couch with her feet and knees up, the way she was sitting made her nighty roll up her legs and I could see between them, I noticed she wasn’t wearing any panties, her little bald pussy looked nice and juicy and it made me hard.

I had my hand down my bottoms playing with my hard cock and I got really horny, then I came up with an idea, “Do you want to play doctor?”, and she said yes, so I said we should go play upstairs in her room.

We went upstairs and I said I’ll be doctor while she was the patient, she sat on the edge of the bed and first I held her little hand and checked her pulse, then I said “I need to listen to your heart. Lift your nighty up.” And she lifted it all the way up above her chest, her little naked body was cute, I put my ear to her chest and had her nipple tickling my ear while I pretended to listen to her heart beat.

When I had my head against her chest I could smell her, she smelt so good, like fresh baked cookies, “Okay, let’s check your temperature, but I need to use my special doctor’s tool.” I said, then pulled my bottoms down and let my just let me cock hang out.

I took hold of my cock and stepped closer to her and pressed my tip against her lips, she leaned away, “It’s okay it’s to check your temperature.” I said.

“How?” she asked.

“Well, you put it in your mouth and suck it, then if it goes hard it means your sick.” I explained, “Now open up.” I said.

She moved forward again and opened her mouth eagerly, and I slid my cock across her tongue as I pushed it in to her mouth, she sealed her lips around it and slowly started sucking, it only took about 30 seconds for my cock to swell in her mouth and get insanely hard, she slurped her lips off it and looked genuinely shocked when she saw how big and hard it was, “It’s hard. Am I really sick?” she asked, worriedly.

“Oh no – you’re right. I think you are sick.” I said.

“What do I do?” she asked.

“Okay, uhm – take your nighty off – quickly.” I said, and she did, she grabbed hold of it and pulled it off in seconds, “Now lay down on your back” I said.

She laid down, and I kneeled on the bed by her feet, “I need to inject you with some medicine to cure you.” I said.

“Okay.” She said. God she was so easy. And a dumb ass.

I spread her legs apart and leaned over her, and the tip of my cock was now rubbing against the slit of her pussy, “What are you doing?” she asked.

“Do you see these…?” I said, showing her my balls, “Yeah.” She replied, “…Well, the medicine is inside these, and I use this…” pointing to my cock, “…To inject it, and I have to inject the medicine in here.” I said, pointing to her pussy, “Or you’re going to die.” I added.

“Okay.” She said, sounding very concerned and worried.

I pushed my cock in to her slit several times, getting deeper each time, and then I felt her pop, my cock went inside of her and she screamed, “Oouuch!!”, but I ignored it and get going, and I started thrusting in and out of her, her pussy was so wet and tight, “It hurts.” She blubbered.

“That’s good. It means it’s working if it hurts.” I replied, grunting and pounding my cock in to her little body, and she started moaning, “Ungh – Ooh – Ungh”.

I confused her more by kissing her and licking her face, I had my hands underneath her, squeezing her tiny butt cheeks, and listening to my balls slapping against her soft bouncy flesh, I felt myself about to nut, “Okay it’s coming, here comes the medicine!” I announced.

“Yeah – Ungh – Okay.” She gasped in response.

I thrust in to her several more times at a fast speed and I held it in for as long as I could, until I couldn’t hold it any longer, and my sperm just exploded out of my cock, I felt it all shoot out and drowned my tip as it filled up her small empty space.

She went limp, her arms and legs falling to her sides, and she lay there heavy breathing, covered in sweat, I waited for my cock to go limp and then I pulled it out and my thick semen flowed out of her pussy on to the sheets and my cock and balls were all sticky.

“Am I going to die?” she asked.

“No – You’re cured now.” I replied.

She smiled, “Yay!” she said, sounding very relieved.

I got up and put my bottoms back on, my legs felt a bit wobbly from the amazing sex I just had, Natalie’s pussy was good.

That was the day I figured out she was such a dumb ass and so easy to get in to bed, and I used and abused her dumbness regularly, I fucked Natalie as much as I could, whenever I could, and still do to this day, though we don’t play doctor anymore, I just tell her I want to fuck and she happily opens her legs for me.
