Revenge On My Sister In Law :)

My sister in law is one hell of a sexy lady and a beauty. She is also a narcissistic monster who makes Hilter look like Mother Theresa!

I tolerate her for my wife’s sake, who is not as beautiful as her sister but one of the nicest people on the planet. My sister in law has just stayed the weekend, and I was very naughty.

I made her several gin and tonics over the weekend, and before bringing them into the living room, I stirred the drinks with my cock and made sure I wiped my cock around the edge of the glass. She always brings her shampoo, which happens to be extremely expensive. She leaves it on the dressing table in our guest room. The fluid is white, and after a bit of self-love, I deposit some extra man-made shampoo in the bottle. Tonight I cooked for the two sisters so they could have a catch-up. The main course was heavy, and they wanted a break before dessert, so I left them gasbagging in the dining room and I went to watch TV. About half an hour later, I decided to serve dessert; Madagascar vanilla yoghurt and fruit. You’ve guessed it; my sister in law’s had an extra deposit in it. Out of character, she commented how lovely it was; maybe she enjoys the taste of man fat and yoghurt? I smiled and said, “thank you.”
