Sister-in-law Fun 2

I was home from work and my wife was working late when the phone rang. Upon answering it I found out it was Cindy. She asked if I was alone and I said for the time being I was. She proceeded to tell me how much she had enjoyed our session of last week. I told her yes, it was fun, but we better quit talking about it and not bring it up again. However she kept on talking about how turned it had made her and how she had never had such a big cock and had never had such an orgasm as I had given her. Well, this was having her desired effect on me as my cock as hard as a steel rod. She asked me if I was hard as she was so wet talking about it and then she started rubbing her clit as we talked. Her voice was driving me crazy as I listened to her moans and her trying to talk with me. I couldn't help it, and I pulled mr. johnson out and it was leaking already. I painted a picture of it for her in words and what I was doing, stroking and squeezing my nuts. She went crazy and started masturbating like crazy. She put the phone down so I could her and the sqwishing noises as she masturbated. I could her moaning and it just drove me crazy. I felt like electricity was running through me. Anyone who has had good phone sex knows how exciting it can be, especially if your partner is good, and trust me, Cindy was good. She had me going good. The excitement, the pure energy coming from her almost had me shooting right there. She proceeded to tell me how she would suck my dick and then fuck me and was so descriptive it was like having actual sex with her, and god her voice, it was so sexxy. I then chimed in and described what I would be doing to her, eating her out and then piledriving my thick cock into her pussy, driving it in all the way and fucking her until she almost passed out. That did it for her. She came so fucking hard and screamed through the phone.  And it went on and on. God, she came so hard I couldn't hold back and shot, moaning and groaning as I shot stream after stream watching it hit the wall. That literally drove her crazy and she came again. We were both , at this time in the thoes of sexual madness and were out of control. I never went soft and she just kept masturbating and telling what she was doing making me mad with desire, wanting to be with her again.    We finally came down from our sexual high and common sense came back to me. I told her how good this was, but we really shouldn't be doing this as it wasn't helping. About this time my cell phone rang and I dismissed myself quickly to answer it. OMG. Cindy had sent me a pic of herself masturbating and omfg, it was so fucking hot I couldn't believe it. She looked like a porn star, so beautiful and sexxy. I went back to the land line and she asked me if I liked it. What could I say? It was one of the most beautiful pics I had seen. And I told her so. Cindy asked for a picture of my cock so she could picture me for later use. I sent her my profile pic and when she got it she told me it was so beautiful and she was going to masturbate to it every night. We both agreed that phone sex was an alternate for the real thing, and with her, it really was, but we had to keep this to ourselves. I really don't know what to do. The sexual excitement rivals anything I have every experienced, but she is still my sis in law and I know this shouldn't be happening, but the attraction is there.  What will happen next? I don't know. There might be a part 3 or there may not be. Time will tell
