I just couldn't help myself


I'm not proud of this, but it was the biggest turn on of my life so far.

My sister is Joanne. (Jo.) She is getting on for 19 and is really into fitness. Lately, because she is not working, she had to let her gym membership lapse and has taken up running.

The other day, she left the house around 10:00 and went for a run along the seafront. It is hot here at the moment, and when she got back a couple of hours later, she was sweaty. I noticed as she walked past me that she smelled terrific! She ruffled my hair as she walked past and said 'Hey dickhead' I got hard.

She went upstairs to shower and I followed, intending to go to my room for a wank. I saw a trail of clothes in her bedroom. A t-shirt, vest, bra, jogging bottoms and panties. The panties were nothing sexy at all. IN fact they were green and kinda school-knickers type. Then I noticed how wet they were. I nipped in and picked them up. They actually FELT wet too! Then I smelled them. HOLY FUCKING SHIT. Pussy, sweat and pee too. All kinda mixed. I couldn't wait and got my cock out and jacked right there. I covered the end of my dick with the wettest part of the material and blew my load into them. Then I heard the water shut off and had to leave them where I found them. I darted back to my room.

FUCK my heart was going like a hammer. I had just done the worst possible thing. Smelled my sister's pussy and jacked into her panties. FUCK how wierd is THAT. Thing is, it made me feel so alive. Then I realised she would find her panties with a load of sperm in them. She would easily work it out.. and she did. My bedroom door flew open and she stood there wrapped in her towel with the panties in her hand. 'You did this?.. you dirty little c....' The next thing she was flying at me and beating the crap out of me. (I deserved it I guess) But something happened. Jo started to push against me and her punches became more slaps and then she was grabbing me. I had gotten hard again. Her towel had fallen to the floor and she was only wearing a small pair of panties. My dick was flat against my stomach and she was riding it. Suddenly she went 'Hunnnhn Huuunnnnnhhhhhhh' and I felt wetness run between my legs. SHe collapsed on top of me.

After a few moments she raised herself up and looked at me real calm and said 'Well. Looks like we discovered something huh?' Jo had obviously cum, but she had peed herself too. I realized that she had not had a boyfriend for ages and, well, I guess she just had to cum. We talked about it for a while and she said that she didnt mind me using her panties, and that she had kinda thought it was real kinky to cum with her brother. I told her I liked it too and that I found it kinky too. Then she asked me if I had gone the whole route yet. (No.) She told me that if I wanted we could fool around some more. As our parents were out for the day I figured why not? So we spent the whole day naked together and did lots of things. It turns out Jo likes wetting herself. I found that I loved watching her pee, either naturally or in her panties. I also found that I liked it on me. Jo loves being fingered and she loves her ass fingered too. Brother/sister? trust me. If you want kinky sex, THIS is the best it gets.

Jo told me that she has masturbated thinking about me before, and has even jilled off thinking about dad too.

Since that afternoon we have fooled around a lot.
