My heart leapt into my mouth, hoping she wouldn't hear me, because one thing I forgot to mention is that although I'm quite shy normally, I tend to be quite noisy – loud, even – when I have sex of any kind.

So she replied ok ok, I asked to tell me about itShe replied hardik your didi is in periods so she brought those pads from market and told that she had to bring it for one day only to which I asked why for 1 day they remain for 7-8 days.She replied yes and told me that it was her last day of periods and she gave me other knowledge about her periodsAfter this all things I started asking some sex relating questions to her and she was also replying the answers.

They then started kissing and Rob started grabbing Lucy’s breast and sucking her nipples. Rob then started taking Lucy’s shorts off. I still can.
