After we reached her mother's house, we introduced our friends to her mother, and had some tea and snacks. Since we had already had beer and snacks (and sex) on the way, we were feeling sleepy, and so decided to go upstairs, make the beds and have a nap.
Her mother rarely used to come up, only when it was absolutely necessary. So we were assured at least of some amount of privacy.
We went up, and Niharika came up with us, ostensibly to help use make the beds. As we were walking up the steps (which were not visible from the main living room, ) she was walking ahead pulling Vikas and Tushar's cocks as she had put her hands up their shorts. I was amazed to see how boldly she was behaving with her mother just a few feet away. The guys each had a hand on the cheeks of her ass, under her dress. And I brought up the rear, looking out to see that her mother was not following us.
As we reached up, she showed the boys where the mattresses, sheets and blankets were, and instructed them how to lay them out. The as they started laying the bedding, she pulled up her dress and called me to lick her. She was standing with her legs wide apart, and I knelt down I could smell the strong odour of her cunt from a foot away. It was glistening and the lips were swollen. She was very wet because I could see some of her juice running down her leg, so I knew that she was still very turned on. I started licking her cunt as she leaned against the wall. The boys stopped their work and were watching. I signaled one of them to go and stand near the steps which were in the other room. I gave her a couple of licks and pressed down on her clit with the tip of my tongue, and move it back and fort a couple of times. She suppressed a moan by keeping her mouth tightly closed, and before I knew it she was trembling and then convulsing in orgasm. She started laughing softly at how soon and how easily she had come. I asked her how it was and she said it was one of her best, but not as good as the one when all three of us had licked her.
For the next two days we were mostly on the top floor, but Niharika could not indulge her liking for being nude as there was always the danger of her mother catching us. But we spent many hours in conversation about how we could raise the eroticism of our activities. During these conversations, Niharika used to have her long t-shirt nightie pulled up to her navel, and one or the other of us would either be fingering her or licking her cunt, and sometimes she was left halfway as her mother called us down. Tushar and Vikas wanted to add at least one and maybe more of their friends to the raise the excitement level, and Niharika eagerly agreed to this.
