Seeing my sister standing at the end of my bed touching herself was such a turn on, but the fact that she had been watching me wank, was enough to stop me from wanking. Lyn,(my sister) told me that she enjoyed watching me wank, she told me she had been spying on me for a couple of months, and that watching me had always gotten her very wet. She told me to move over, and sat on the edge of the bed, with her legs half open, exposing her panties towards me. I could see a damp patch. 

 

She asked if I would mind if she watched me wank myself, saying I could feel inside her panties if I wanted to. The thought of touching my first pussy, and it being my sisters, got me fully hard, and my hand returned to my cock. I started to wank slowly, as she watched, still fingering herself in her panties. I desperately wanted to touch her, but was too shy to ask her. She saw that I was staring at her panties, and asked if I wanted to feel her pussy.

 

She moved her hand away, and pulled her panties to one side, exposing her pussy hair to me. It was very light in colour, and there was not much hair. (Lyn was a few weeks short of her 16th birthday, she was about 5'2, very slim and was a natural blonde). As I started to stroke her, I realised how wet and slippery she was, and she moaned a little as I managed to slide a couple of fingers into her. I was wanking a little faster by now, and I saw her staring at my hard cock. I asked if she wanted to touch it, and soon she was wanking me quickly. I always enjoyed getting wanked by someone else, but to be wanked by a girl for the 1st time, and that person being my sister, was almost too much for me, so I asked her to slow down otherwise I would cum.

 

Suddenly we heard a voice, it was Mum telling us that her and Dad were going to bed, and not to stay up too late, I called back that Lyn and I were watching a film, but would go to bed soon, then footsteps, then silence.

 

We resumed what we had been doing, she was wanking me quite quickly now, and I was sliding a couple of fingers in and out of her, suddenly she put her hand over her mouth and moaned, as I felt her body shake, she had cum, (I had read about female orgasms in magazines). She continued to wank me, a lot faster now, and before I could tell her I was going to cum, I exploded all over her hand and nightdress. Lyn continued wanking my cock until my cum stopped comming out. She then took her hand away, I reached for a tissue, but she licked my cum off her fingers.

 

As we lay on the bed, she asked if she could do it again for me sometime, I told her I would love her to, and that I would be ready to go again in about 20 minutes. She told me she was going to go and change her nightdress, after all it was now covered in cum, but she would be back in about 10 minutes. While she was away I thought about what had just happened, it had been so unexpected, but had been such a turn on.

 

10 minutes later, I heard her leaving her room, and then she came into my room. She had changed into a slightly longer nightdress, but it was almost see through, I could see her tiny hard nipples, and her pussy hair through it. She came over and sat next to me on the bed, she asked if I liked what I saw, but my cock hardening answered her question. I reached down and put my hand under her nightdress. I was going to feel her pussy again, but she took my hand and put it on her little boobs, her nipples were so hard, and she shuddered as I stroked her nipples. I used my other hand to touch her pussy, she was still very wet. I felt her fingers on my cock, then she started to wank me slowly.

 

My fingers in her pussy were wet by now, I wanted to find out what she tasted like, so took them out of her, and licked them, she tasted nice. I really wanted to kiss my first pussy, so asked if she would lie on the bed next to me. She did, then I sat up and opened her legs, before I moved my face between her legs, and started to lick her pussy lipps. As my tongue entered her pussy, I felt her shudder again, I knew she was enjoying this. She asked if she could suck my cock as I licked her pussy, so we moved until her pussy was in front of my face, and my cock was close to her mouth.

 

I moved my head close to her pussy, and as my tongue slipped inside her, I felt her lips on the head of myy cock, soon she was sucking it hard, and when I tried to tell her I was going to cum, she pulled me further into her mouth, just as I started to cum, she managed to swallow some of it, but spat a lot out.

 

She sat up and told me she would learn to swallow more if we did this again, I told her I was looking forward to the next time. She started to get ready to go to her room, but I asked her to stay with me for a bit, so she snuggled into me, as we watched what was on the tv.

 

About 10 minutes later, I felt my cock begin to stiffen again, her lying in my arms, while I stroked her nipples had got me turned on again. Lyn felt me harden and asked if I wanted sucked again. I told her I loved the idea, but asked if we could try something different. She asked what, I suggested that we had sex, to begin with she looked scared, saying my big cock was too big to get into her, but then agreed that we could try.

 

She sat up, and took off her nightdress. This was the first time I had ever seen a female naked, well in the flesh anyway. Her body was lovely, she was very slim, with tiny little boobs, about a AA cup, (she is not much bigger even now). She sat between my legs and started to wank me slowly, I put my hard between her legs and realised how wet she still was. She asked how we were going to do this, she told me she was still a virgin, I told her this was my first time too.

 

I suggested that if I lay back, she could lowere herself onto my cock, and she could stop if it was hurting her. She agreed, so I lay back, slowly wanking my cock, as she knelt over it, then started to rub her pussy lips on the tip of my cock. Slowly she lowered herself onto my cock, I could tell she was in some pain, but she continued to lower herself until the full 8" of my cock was in her. She started to slide up and down my cock, and in a few minutes she came, but continued to move up and down on my cock, until she felt it shudder, then lowered her pussy as far as she could, before I filled her pussy with my cum.

 

Lyn sat on my cock until it went limp, then she leant forward and kissed me fully on the lips before she took herself off my cock. As she was leaving to go to her room, she asked if this had been a one of, or could we do it again . I told her we would do this for as long as she wanted to.
