With my neighbour's sister Part 1

I(M35) recently shifted to Pune from Mumbai in a rented flat for work. I'm single and prefer to stay alone in the house. Few days back I saw a beautiful girl on our floor entering my neighbours house...didnt really thought much about it and got back in my own world but after 2-3 days I saw her again on my floor we just looked at each other and crossed paths but while crossing she took a nasty fall and was hurting I quickly asked her if she is okay, helped her to stand back and gathered all her belongings she replied back saying idk what really happened but Im okay she thanked me with a smile and left. I was returning back home from work and saw her taking a walk in front of the building I just parked my car and started walking towards the entrance, entered in the lift I saw her coming towards the lift I stopped it and let her enter the lift she gave a nice smile and I asked her If she is okay she replied back showing her hand is little swollen but she is fine. I told her that I have never seen you before to which she replied she is visiting her sister and BIL for a month and thats it..for the next 2 days we kept bumping into each other and greeted with smile or simple hello but on the 3rd day it was weekend she was taking a walk saw me coming out of the gym she came towards to me we greeted and started talking about our lives and all I came to know that she is also from Pune(never bothered to ask her age but by the looks she must be 32-33) and decided to visit her sister before she joins a new company, that evening we were together for 2-3 hours talking, walking, sitting in the garden we connected so well even exchanged our numbers and started chatting the moment we reached our places it was like we knew each other from a long time we were just chatting about anything and everything except sex I guess we both were looking at this relationship as good friends this continued for a couple of days and we were very comfortable with each other. I was wfh and was chatting with her she told me that her sis is sleeping &
