I mean; I think it finally clicked in my head this morning. I had passed off that master-slave demonstration the girls put on today as just a lot of f...un the girls were having as a lead-up to all the sex. Then, it dawned on me that you didn't give me hell yesterday for violating the best-friend-and-sister rule."All guys knew that male best friends did not date or fuck the sisters of their male best friends. It just wasn't done. I realized now that I should have at least made a pretense at. Over the next three rounds of beers, I learnt that Luke is the new man in Ashley’s life, but is very new (like two weeks new). There are always new guys coming and going with these two.Luke seemed like a nice guy and really funny.As we finished our third beers it was my shout (that is a colloquialism for it being my turn to get beers from my fridge). Since the sun was getting low one of the girls suggested we go for a quick swim before it gets too late. Everyone agreed.I was dressed for a swim. “What a disappointment. Had I behaved the same way in the city, I would be at the center of a 24×7 gang bang.” She said to herself.Kanti’s vacation was coming to an end. She had failed to achieve what she pledged to, five weeks ago. Though it wasn’t a complete failure. She had taught villagers to take pleasure through their mouths as they started kissing publicly. But that wasn’t enough for her.After a long detour finally we come back to the present. Kanti was standing on the stage with her. The know-better-do-better situation was staring Natalie right in her face again. And of course Natalie earned a big fat ‘F’ once again. “No, I don’t want out,” Natalie was amazed at the words leaving her mouth. It was as if a virtual demon was shitting on her brain. She was an independent, intelligent, bright, and good-looking woman giving into a narcissistic sex maniac. “Okay, I’m in. What’s next?” “’At a girl. Judy will receive the next instruction. Then call me back on Skype.” Natalie.
