After puckering up for a couple of minutes we broke our kiss, andstarted the next game.I won the next game, and I asked the girls to kiss each other. ...hey were slightly reluctant at first,but I said rules were rules and they can’t refuse. I was so turned on when they finally did it and the bulge in my pantswas evident. Priya won the next game again, and she asked us both to strip down to our under clothes. The bulge was veryobvious in my boxers by now, and even more so from looking at Abhilasha. I couldn't even get hard with him standing there waiting, so I just sat on my bed, and looked at the floor. I guess he got annoyed, because he told my sister to suck him instead. I looked up to see my sister on her knees, bobbing her head up and down on his cock, with him holding her head tightly, trying to get deeper in her mouth. He groaned and held her head tight as his cum filled my sister's mouth. It was obvious that she was doing her best to swallow, but some shot out the corners of her. Many times I used to get up at mid night and see sleeping sister and many occasions I could see her thighs, buttocks when dress has moved upward . But I was never luckier to see her small but beautiful balls. One such opportunity came by itself . That day was Saturday and I returned from tuition class and my sister served me food and told that she will go for bath. Since I was very hungry I was enjoying the food sitting on the chair which was opposite to the bathroom door . By accident my. Honestly, Sonam didn't want to wash this piece. To her this was a memorable and valuable keepsake of her first conjugal union, of some heavenly moments of sheer joy, with her amazingly virile father-in-law. How wildly and lovingly he had flooded her vagina with his thick cum, and it was this sticky goo that had been rubbed into this fabric! She would never want to wash those first traces of his fertile cum. It was something Sonam wanted to preserve, and savor the moments when she would be.
