As I dropped Niharika home, she described in great detail what had happened after I left, and I was aroused to hear of one more cock being added to the team. Since the episode with Sheetal had also unlocked another experience for me, Niharika now enthusiastically started licking and sucking my dick. And had made me cum and swallowed before we reached her place. This later happened many times while I was driving. I asked her whether she would suck the boys off, and she said that she would taste them first after Sheetal had sucked them off, and then decide.
I discussed what we would do next, with Niharika. I had to make sure that I had covered all the options, like licking Sheetal, fucking Sheetal, having the boys do those to Sheetal. Niharika said that we could do whatever Sheetal allowed us to do, except that I would not fuck Sheetal's cunt. The only cunt that I was allowed to fuck was Niharika's and that too after marriage. I was OK with that, as I was able to do lots of other things, which would not have been allowed by any other woman.
I was sure that Sheetal had already had or would like to have anal sex, since she wanted a metal butt plug to be fitted in the harness. The design she had specified was such that either the short or long end would always be in her ass when she was wearing the harness. Also if she was wearing jeans or shorts, he would have to have the long end in her asshole, otherwise it would show a know through the clothes. Niharika said that she hadn't realized how much of a slut Sheetal was, and wouldn't have if she had not been wearing the necklace. She also told me that the ball pressing on her asshole was creating new sensations for her, and when she was walking with the boys, since her clit was not being stimulated it was the ball on the asshole that was arousing her as it has rubbing on her asshole as she walked. I was excited that she was loosing her inhibitions regarding her asshole.
I had kept her harness with me. since she also wanted it to be modified. Finally I decided to make two new harnesses instead of modifying so that they could have a choice in what they wanted to wear The new harness had the waist made such that the sides were higher than the front and back, like some bikinis. The sides were just above the pelvic bone, whereas the front dipped to just above the slit of the cunt in the front and below the cleavage of the ass behind. Knowing that Sheetal was much bolder than Niharika, I knew that she would use this imaginatively, and encourage Niharika to do so.
