My fingers got lost in my sister

It happened to me in 99, I was 17 years old and my sister was fifteen, we were at a colleague's house, we had a little wine and by the way, I don't know why we went to the bedroom, had a double bed and a mattress that was between the side of the bed and the wall, I was lying on this mattress with my boyfriend at the time and my sister was in bed. Me and him started joking, but as my sister was there she said we weren't gonna have sex, we thought my sister was sleeping, I went down and started sucking his dick, so I noticed that my sister was looking, I thought if she stopped or not, I don't know why, maybe because she drank, it kicked me out, kept sucking until he came, he didn't notice that she was looking, at least I think. We went down a little bit, the more it got in my head, I said I was sleepy and I went to sleep, I said I was going to sleep with my sister, he stayed downstairs with the others. I went to the bedroom and I thought if she was going to say something, I don't know, maybe I'd want to explain myself. I lay next to her and we started talking, I don't know what got into me right now, maybe because I was a little drunk and I didn't make fun of that time, and the image of her looking at me, it was giving me a huge hard-on, I had to come, but I didn't think to do anything with her. We kept talking more she touched the subject than she saw, plus my curiosity of knowing what she had thought was bigger, I couldn't stand it and I said - I saw that you were looking - she said that she saw that I had noticed, more that she got horny so she kept looking, and she said that I thought I was beautiful sucking a dick, at that time I looked at her, she looked beautiful, just with a camiseton and panties, her legs were so beautiful, so we continued to talk about sex, things like sucking dick, masturbating in the bathroom, letting the boys run their hands over their panties, things like that. By that time the horny was huge, I couldn't bear to put my hand under my panties and I started masturbating, I had never masturbated around someone, she saw it pushed her panties aside and started, her scene masturbating made me horny, seeing her rubbing and her fingers disappearing inside her crack, making me crazy, masturbating just looking at her hand in her pussy, I forgot at that time that I was looking at my sister, she asked me why I couldn't stop looking at her pussy, I got no answer, but I had to say something, then I said that she masturbated in a different way, that I wanted to learn. Then she said -so keep looking -, and she kept masturbating, her fingers went in and out of her pussy, she could see her fingers so mellow by the size of the horny she was feeling, she started passing strange thoughts in my head, I looked at those humble fingers and I felt like feeling the taste, I saw that pussy so beautiful, so young that I wanted to be able to touch, suck, lick, then she asked if I had learned, I said that just seeing I couldn't learn, then I asked if she would take my hand and put it to show me, to my surprise she accepted, took my hand and put it in her pussy, my fingers soon slipped into her crack, I saw them coming in and out of my sister's pussy, I saw him wetted with my sister's horny and wanted to put them in her mouth, to be able to taste her. Then she took her hand and put her hand on my pussy, her fingers soon got lost inside my pussy that was already soaked with horny, we continued to masturbate to another, it was wonderful to see that my fingers could go through all that beautiful pussy, she raised her shirt and left her breasts appearing, and with one hand she caressed them, I looked at her breasts, then at her pussy, I was in ecstasy, I saw my humble fingers with her joy and wanted to feel, I didn't feel it, and I brought my fingers up to her mouth, and I started sucking on her beautiful belly until I reached my own sweetest kiss, a little bit sweeter, my tongue lost in that beautiful pussy today, the more I started putting my hand on her whole body, I started to caressing and sucking her breasts, I went down by her gorgeous belly until she reached my own sweetest cheek, and she said to me in my beautiful legs. I hope you enjoy my tale. If you want to write to me. A Hug
