Feeling stupid standing around, I dragged a chair and sat down to watch the forbidden love between a brother’s tongue and a sister’s clit continue...before me. Anjan was now visibly tiring, using his finger more than his tongue, and despite Janani’s regular discharge of cum, she still hasn’t had a proper orgasm; I, in the meantime, was gleefully jacking off to the sight of my best friend and his sister behaving like a couple of horny college kids. Janani’s eyes were tightly shut now and she was. The rear room joins onto their conservatory. I thought they used the conservatory as a spare room when Gita’s parents visited and from the doorway I could see I was correct as there was a bed set up in there plus a small table and a few other small items of furniture. It was an iron-framed bed and Gita was tied naked, blindfolded and spread eagled to it. I froze and at first thought I was interrupting a crime scene or something. I looked around incase they were and burglars or something.. It was a strange feeling, to be more scared for someone else than for yourself. To be ready to step in and give yourself up for another without that being asked of you. It was what she was ready to do. Because she understood what M had meant. He wanted to win and the game that he was playing was between him and Nick. And the prize, well that was simple. She was the prize."What does it take for you to win M?"There was silence on the other end of the phone, for a moment she thought he had hung. Then she asked me to zip down her dress, so I stood up behind her and put my lips on her neck while I slowly zipped down her dress. At that point my dick was hard as a rock! I started rubbing Gini's body and squeezing her big ass tittys. Gini leaned her head back on my and lifted up her arms so I could pull the dress off. She stood there in her bra and panties. I turned her around facing me, then I took a step back and sat on the couch. I wanted to admire her figure and it was so exciting.
