It was just a social visit, but I had timed it so that I knew she would be alone, and I hoped it would turn into more than a social visit. I had been flirting with her for some time. My sis-in-law is a cute gal with a sexy body (just like my wife), and my wife had told me that the two of them had played in bed together when they were growing up. She let me know that they had often explored each other's bodies and sucked each other's pussy. My wife and I have an open relationship, and we have both had a few outside lovers. Her sister, on the other hand, is married to a rather prudish guy who would never let his wife have an outside lover (if he knew about it). I had told my wife that I would love to "get your sister in the sack sometime," and she just smiled and said, "Go for it if you think you can." Long story short, I did get my sister-in-law in the sack that day that I visited her. Clearly, we both enjoyed our intimate play, and I told her I would be telling her sister about the fun we had. She already knew that my wife and I have an open relationship, but as I got ready to leave she was showing signs of embarrassment about what we had done, and the thought that I would be telling her sister. Naturally I told my wife about my play with her sister, and she was fine with it. The following Wednesday my wife and I went to her sister's home at about 10 in the morning. We knew her hubby was at work, and her children were at school. When we arrived she was busy doing her laundry, wearing only a wrap-around skirt and a blouse. I knew she tended to dress like my wife (no panties or bra underneath). She blushed as soon as she saw us... especially when she saw me. She tried to avoid looking me in the eye, and seemed to be trying to keep her distance from me. My sister-in-law went to the kitchen and started preparing tea for us. She called my wife out to the kitchen. My wife caught my hand and pulled me with her to the kitchen. Now there was no way my sister-in-law could hide from me. So, she hid her face in her palms, and sort of giggled as she looked through the gap between her fingers toward me. I just made a show that I was not looking at her, and sat down at the table near the kitchen door. If she wanted to leave the room, she had to cross by me very closely. I sat there enjoying the tea. Soon my wife went to her sister and started to talk with her, letting her know that I had told her about the fuck session I had had with her. My sis-in-law's back was toward me, and my wife was facing me. My wife was smiling, and letting her sister know everything was OK. Slowly, while talking, my wife started pushing her sister toward me. Soon my sis-in-law was very close to me. I lifted both of my hands, caught her by her waist, and pulled her onto my lap. She tried to get up, but my wife (with a grin on her face) kept her hands on her sister's shoulders and pushed her back down. From behind, I cupped my sis-in-law's tits in both of my palms. Then I pushed my right hand inside her blouse, caught her nipple, and started tweaking it. My wife unbuttoned her sister's blouse, opened it, pulled on it, and removed it completely. I caught my sis-in-law by her chin and kissed her so hard that she was breathless. Then I simply unsnapped her skirt, pushed it down, and she was fully naked. I lifted her by catching her thighs and rested her buttocks on the kitchen counter. By holding her legs on my shoulders, I bent in between her legs and started playing with her clit with my tongue. While I was doing that, my wife removed her own dress, my pants, and my shirt. We were all fully nude in no time. My wife slowly pushed me away and caught her sister by her buttocks. She pulled her sister close and kissed her fully on her lips. They were so engrossed in the kiss that they seemed to have forgotten about me. Soon the two of them were lying on the kitchen floor. My wife was on her back on the floor, and her sister was above her in the 69-position. They started sucking each other, making noises the likes of which I had never heard before. I saw that my sis-in-law was sucking my wife's clit like a suction pump, with her lips making smacking sounds. Both of my wife's legs were up and open to the maximum. Watching them was a big turn-on, but I wanted to get in on the action. I went behind my sis-in-law and pushed my erect cock into her pussy from behind, and started pumping. My wife caught me by my buttocks and pushed one of her fingers into my anus. I was holding her sister by her waist, and pumping her hard. When we all came, it was thunderous. We all collapsed over each other, trying to catch our breath. As we were recovering, I saw my wife licking my cum from her sister's puss, and her sister was using her tongue on my wife's clit. Then both of them came over to me, laid their heads on my shoulders on both the sides, and started kissing each other across my chest. Some minutes later they turned around, moved down my body, and together they started sucking and licking my cock, in between their kisses. Both of them were playing with my cock. They made my cock to stiff again. By then I was lying down, and my wife rode me. Her sister played with us... sometimes kissing me on the lips, sometimes kissing my dick where it was joined with my wife. Once she held us still and started sucking my wife's clit while my cock was inside her. My wife's spasms from that treatment were so great that I came with a great force again, and lay back, exhausted. But still they still had not fulfilled their lust. For nearly two hours they played with each other. I was only a spectator who was allowed to watch, but not to interfere. I really enjoyed their playing with each other. Now, whenever I get the chance I bring them together, and I enjoy watching them play with each other. My watching seems to encourage them. Sometimes it is just them playing and me watching. Other times they invite me to take turns pumping my cock into them until they climax. Then it is my turn to pump a load into one of them. My sis-in-law is always ready to suck out the cum I deposit in my wife.
