Fucking my sister in a heatwave

We had the hottest week in years, not just temperature wise, but physically too. My little sister and I ended up having sex, multiple times.

On Monday and Tuesday we had a really scorching hot heatwave, it was so hot that even the slight breeze wasn’t cool, it felt like someone was pointing a hairdryer at you, it was just absolutely boiling hot, like all day, all night, all the time.

Me and my little sister Sara, she’s 8 and I’m 15, were lucky because we had an inflatable paddling pool to sit in and cool down, even getting the hosepipe out and water guns, but at night it was still boiling hot.

My mom and dad went out with their friends in town, they didn’t want to stay inside all night, so they went out for drinks, leaving me to look after Sara on my own.

I left Sara in the back garden splashing around in the paddling pool, she was wearing a swimsuit during the day, but got dressed just before our parents left, then when we realised it was still boiling hot, she took off her clothes and jumped in to the paddling pool wearing only her panties.

It got too hot for me outside so I went in and sat slumped on the sofa with the fan blowing cool air over me, I took my top off and just say there in my shorts with a cold can of Cola rubbing it against my head and chest to cool down.

About an hour later Sara came in to the house looking for me, normally I wouldn’t take much notice of her, but she was only wearing her panties, and they were soaking wet, and were see-through, I could see her little pussy right through the fabric, still I ignored it at first, but then she got giddy and decided to jump on top of me.

“Are you coming outside?” she asked, all giddy and giggly.

“No, it’s too hot. I’m tired.” I replied.

She was sat, facing me, straddling my lap, with her hands on my shoulders, the water from her wet panties began to be absorbed by the fabric of my shorts, the wetness and how she was sitting on me gave me an erection and she felt it bounce underneath my shorts, and twitch between her legs.

She wiggled herself off my crotch a little, then reached down and touched my cock over my shorts, “What’s that in your pocket?” she asked.

“Uhm – nowt.” I replied, feeling a bit embarrassed.

Then, being the curious girl she’s always been, and not believing my answer, she yanked down the front of my shorts and my erection sprang up and out of them, she gasped when she saw my big hard cock bounce up like a jack-in-the-box.

I was in shock for a moment, my little sister had seen my cock, and I thought she was going to freak out, and started to think of all the things my mom and dad will do to me when they find out, but then she quickly put me at ease.

She giggled, “Your dick is really big.” She said, and she touched it.

“…Thanks…” I said.

“Thomas’ dick is a lot smaller than yours.” She explained, Thomas is out cousin, he’s Sara’s age, she sees his dick sometimes when he’s using the toilet upstairs because he always leaves the door open, now she was comparing the size of mine to his, “Do you mind me touching it?” she asked.
She was rubbing my cock quite nicely, examining it with curiosity, I should have told her to stop, but it felt really nice, and I didn’t want her to stop, “Its fine.” I replied.

After a few minutes I suddenly found myself rubbing her legs and I stared in to her big blue eyes and got an irresistible urge to kiss her, I leaned forward and planted my lips on hers and gave her a big kiss, her little face turned red and she giggled while blushing and smiling back at me.

It was so hot and my body temperature was rising even higher with her stroking my cock the way she was, and she was practically naked, just straddled across my lap, delicately stroking my cock, I couldn’t help myself, I gave in to my male instincts, “Get up, stand up.” I said with urgency.

“What? Why?” she asked, as I held her waist and lifted her up until she was standing on the sofa over me, then I pulled down her panties and lifted her feet out of them before tossing the wet panties on to the floor.

She was stood right in front of me, her exposed pussy directly in front of my face, it was wet and sweaty, I leaned in and started to lick her crack, she hunched over me giggling, “Stop it. That tickles.” She giggled.

After tasting her sweaty virgin pussy I leaned back and looked at her while rubbing my hands up and down the sides of her body, she is a small girl, very thin, and in that moment she was the sexiest girl in the world, “Sit down.” I said.

As she began to sit, I positioned my cock so it was directly underneath her pussy, and I held on tightly to her hips as she came squatting down and I helped her push herself on to my cock.

“Ouch..!” she screeched.

“Its okay, its okay.” I said, the heat had made her flesh really soft and tender, and her pussy was soaking wet, which allowed my cock to fairly easily slide right up her tight narrow hole.

“Ooah – Ungh.” She moaned.

She put her hands back on my shoulders for balance, then I started to slowly bounce her on my cock, it slid further inside her the more she bounced, we were both moaning loudly as we both felt my cock going inside her, even though she screamed out at first, she very quickly calmed down and was now just paying attention to me and letting me do my thing, she trusted me.

I was the one holding her and bouncing her on my cock at first, but she soon took over and did it by herself, and for the next 15 minutes I had the greatest sex of my life, we put our arms around each other, holding each other tightly, slowly thrusting my cock in to her as she bounced on it swaying her little hips around.

We spoke no words, just gasped and moaned with pleasure, we basically made slow passionate love on the sofa with the cool breeze of the fan blowing around us, but sweat still pouring off our naked skin.

Sara began to moan a little louder and more frequently as my rate of thrusting increased, I held on to her delicate little butt cheeks as I rapidly pumped my cock in to her, then she let out the most heavenly sound as my cock swelled and I ejaculated my seed in to her pussy, her final moan was so beautiful, so sweet and innocent sounding, it almost made me cry… but I didn’t.

When the thrusting and bouncing had stopped, she tightly her hold around me, squeezing herself in to my chest, I could feel her heart beat on my skin, “Sara, you okay?” I asked, stroking her sweat soaked hair.

She nodded against my chest to let me know she was good.

We rested allowing the fan to cool both of us down, then we went back outside, both of us completely naked this time, and we sat in the paddling pool for the rest of the night.

When it got late and we saw our neighbours lights go out, once we knew no one was looking, at least we hope no one saw us, no one has said anything yet, but once the lights went out, Sara and I made out and we had sex again in the paddling pool.

I know it is pretty bad, I shouldn’t have fucked my baby sister, but I couldn’t help it, and it was so good, even she enjoyed it, so is it really that wrong that we did it?

We haven’t done anything since that night, even though I want to fuck her again, and I think she wants to do it as well, we just haven’t been alone since.
