Suddenly, I heard a voice calling, "John, are you home?" I recognised my sister's voice and answered, "I am out here in the Spa, come and join me." Sh... ran out the back door quickly shedding her outer garments and was wearing just a small bikini. I immediately thought to myself that this was the opportunity that I had been waiting for.I invited her to get herself into the spa, and asked her if she would like a drink. I bought out a bottle of Champagne and 2 glasses. "Why the Champagne John,?". I was sweating and I had almost fainted but collected my courage again and started exploring my sister Khajo’s vagina. I could feel that she was shivering. She did not object at all. I knew now fully that she wants this and therefore, I started slowly but gently exploring her vagina. As I moved here and there, not knowing what to do? As I moved my fingers went downward, and my fingers felt some wetness. I knew that she must have had what I have on my penis. But it was making my fingers slippery. I can feel the pleasure... put it inside slowly and fuck me.... fuck me hard with your cock and fuck me with your finger in my ass...”“You have a very big ass and your anus is very pretty.” I said and pushed my finger in, then retrieving the finger I suggestively put it to my mouth and licked it, more in order to turn her on than to lubricate it. Her cunt flowed enough goo unto the brown hole below. I pushed the finger gently back again.“Gabika loved having her ass licked... I want you... would. And as I said, both of us are quick to take advantage of any opportunity to get the other in trouble.There is one other thing about my brother that I should probably mention. For several years now he has seemed to have an unpleasant and unnatural desire to spy on me. He has been caught several times trying to see me naked. I know that isn't so unusual, up to a point. Some of my friends have caught their brothers being a little more curious than what might be considered normal.But I think that.
