My friend's sister (Part 1: the recital)

Several years ago with a group of friends from way back when we would often go to rock concerts, sometimes there were 4 or 5 of us but in the summer one or two would have gone on vacation. Then the idea was to go to the concert with a friend and then grab something to drink and see where things went. The show was at the Ciudad Club in Capital and when I was already waiting and waiting, this dude calls me and tells me he can't make it and that he has to find his younger sister to let her know stay with her and take care of her and they'll come back together he said you'll meet her, she's the same but a bit more curvy. The last time I had seen her was 4 years ago when she was 16 (I'm 6 years older) but to be honest I had no idea what she was like now, but I was sure I would recognize her. In the back of my mind I always looked at her little girl face with guilt because she was so young but with disguised desires in macho jokes among friends like how did you grow up without thinking about anything more. I arrived at the designated location and the first thing I see is an incredible cleavage: 2 hidden breasts on a muscular white body with a cut-out just right for them to enter comfortably and show the union of the two. I raised my gaze and it was her! The same little girl face and the same mouth with the same mole but now more grown up and with enormous breasts. More curvy said my friend not wanting to admit that his little sister had a front that was crazy. I looked at her for a few seconds, she looked back at me and I got nervous, turned around and quickly looked again, she came over and asked are you the friend of my brother? And we started talking. Divine, very friendly, remembered times when we had crossed paths as kids, so drunk that sometimes I forgot about her mouth and her boobs and everything else, but in a moment she said I'm thirsty! and bit her lips and then I looked at her mouth again, her mole, lowered my gaze and fixed it on those beautiful breasts. I bought some beers and while we were drinking, I thought how am I going to hold back without saying anything, without trying Nothing or act in any way that she might get annoyed and tell her brother? Giddy up because the young lady is not an extraterrestrial, but the unexpected situation made me tense. She told me that her friends couldn't come and that's why she was going to see the recital with her brother. The show started and we had a great time singing, jumping, screaming, there were glances and brushes due to how close we were among the crowd. On the final part it started raining and I couldn't help but look at her, with her wet hair, water droplets running down her neckline and her nipples slightly marked on the white fabric. It was 2 seconds before she realized I was looking at her and turned red. When we were leaving talking about how good the recital was there was a subtle support instance that both of us, even though we could avoid it, let happen. We arrived at a stand and bought more plastic beer cups, walked to the station and just as the joy train was arriving I thought we're chatting and that's it. Sitting next to me and from our heights I could see her neckline from almost a perverse angle, the kitty in the middle of the muscular one was torture for my mind. I searched for something to talk about to distract myself but when she said the guys don't give me much attention I couldn't help but respond they're missing out, you're very pretty girl and think x within don't make a fool of yourself, girl. She laughed and it became like a joke. Or not. She leaned on my shoulder and fell asleep. Her neckline and the way she presented herself already was an invitation to hell, a thousand images passed through my head in seconds and my cock got very hard, I couldn't stop looking at those tits and imagining how I could suck them without stopping. We arrived and I woke her up, half-asleep and leaning her boobs against my arm she asked what do we do now? I remained silent for a second moment because I didn't know what to say to her and because feeling her boobs pressed against my body was an indescribable sensation. Very soft and even hot they felt, and while I thought about all that I kept repeating what we're doing now. We got down and I was accompanying her until her house but she stopped me and said I don't know if you fixed things with my brother but I'm not going to sleep now What do you want to do? I asked and I answered, with the cassette on, that I had to take her home, but she insisted ok, but what do YOU want to do? I looked at her and she had a face asking me to react and her nipples were noticeable again, I couldn't take it anymore and I kissed her, she kissed me back and we ate each other's mouth. You're very pretty, girl I said I have the key to my friend's apartment she replied I was paralyzed and she hugged me, pressing her boobs against me and feeling my erection with her agitated body I know you've always wanted this, you've been looking at me for years with a face like a masturbator and I love it. I'm not a girl anymore she said in my ear and started walking...
