I hesitated at this revelation slightly before spanking her again. Wait... I thought, “Have you tasted your sister’s pussy before or since then?�...� I slapped her less hard this time because I was trying to process what she was saying.“Yes, Master.” She said quietly. I could understand why. I slapped half heartedly. Hang on, I thought, “Has SHE ever tasted YOURS??” I slapped very hard this time, trying to coax the answer out of her. Her knees buckled suddenly but she immediately locked them. I was pretty sure this one will end only by 11 pm. So I called Diya but her number was switched off. I didn’t know that Diya was in my flat. Forgot to tell you guys about my friends. One guy is Mark and the other is Suresh.Mark always had an eye on Diya. He openly said to me that he wants to fuck Diya. But I never took it seriously. So I called Mark and told him about the situation. He decided this was the time because he has got 3 hours before I will be able to reach home. So he told Diya that. Her hands move down on me again but only to find that my hardness had faded away. She stop kissing me and said, I will take care of that and move her attention down on my nipple. She started to suck on one nipple while fondling the other. The feeling was incredible as i never experience that before. With time her hand started to explore downwards again, finding my hardness had returned … Joann said, now that’s better. With that she slowly changed her position and guided her wetness down onto my. I was going to go to my apartment but I couldn't leave you like that. I put your gown on and covered you up. I lay down because I just didn't know what else to do."Damned if I was going to tell her there was five minutes between undressing her and putting her gown on!She seemed to blush even more. I swear I could see the freckles multiplying through the thin gauze of her gown. Embarrassed, she lay beside me and hid her face in my shoulder again. Christ, this was getting to be a habit... not.
