Rene had touched my cock and even jacked it a little. I didn't get to cum but, I was imagining it was her hand stroking my cock when I jacked off. Rene asked me for more sister time so of course I would.  I wore the same dress as the last time and a pair of red panties with little white hearts. She told me she had given him a hand job the next time they went "skating ". I wanted to hear all about it, but she needed more sister time. Dad wasn't due to go out of town for 3 more weeks. Finally I got to hear all about the deed.  He liked it so much her only took a couple of minutes before he popped off, as she put it. Not all the details I thought I would get but she was blushing pretty good so I just let it go. She said Martha's boyfriend said he was impressed with how well she jacked him off he couldn't wait for her to suck his cock. Rene told me she wasn't sure she was ready for that yet. She was worried about doing it and what might happen to her reputation if word got out. I told her I  hadn't heard anything about what they were doing at school. But I wondered if the guys just told each other or if guys at the highschool  knew about it. She looked at me like she had seen a ghost! Do you think they would?  I had no idea. I told her if it wasn't being talked about then she probably didn't need to worry. She asked me if I thought she was a  bad girl for doing a few handjobs. No she wasn't if she really loved him and he loved her. She smiled and said she loved me. I loved her too I told her. She said she did kiss the tip of his rig. I just asked how was it? She said it was OK. He wanted her to give it a lick but she was pretty nervous about it. So she said maybe next time. Which was going to be tomorrow night! I was praying she was going to ask me to help again. I held my breath and she asked if I would let her try on my cock first.  It's a little bigger than his so she wanted to try mine. I told her I would do it but what about the finish? She said she was really worried about that.  She knew Martha said she would swallow his cum when he popped off. Rene wasn't sure if she could. I had no way of knowing what anyone else's cum tasted like, I assumed it was all about the same. Not even close to the truth!  I had tasted my own cum once to see what it was like. I didn't think it was bad at all. I didn't say anything about it to Rene. I just said it might help to know. I wanted to know if getting a blow job was as great as I had heard.

Rene told me that she was willing to try letting me cum in her mouth. But she needed to be warned when. Agreed! My sister was telling me to get ready. I was! I pulled up my dress until my panties were fully exposed. Rene moved over to my side. She pulled my cock out of the panties and asked if I was ready. God yes I was! I think so I told her. She smiled and said that she would show me how she stroked her boyfriend for a minute. She was quite good at it really. I didn't even think about it I leaned over and kissed her on the lips. Soon our tounges were involved and I reach over a put my hand on her left tit. She broke up the kiss with a question. Are you ready to try it with me. Yes! I worried I said that to loud and fast. She smiled and said OK she was ready to.  I had nothing to compare it to. I decided blow jobs were fucking amazing. I didn't want to cum too fast. It had been a week since I had jacked off thinking about Rene doing the hand job again. Now her mouth was making my cock very happy. I lost track of everything except the feeling of her mouth on my cock. She started  licking and sucking my  balls too. I would have to thank Martha for telling her guys like that. I know I do! Rene went back to my cock and in a couple of minutes more I had to tell her I was just about ready to pop. She worked the head of my cock until I told her I was cumming. I  felt like my orgasm lasted a week.  Maybe 6 or 8 varying sizes of cum shots before she was looking me in the eye, before gulp. She smiled and said she liked it better than Martha said she might. My heads both were spinning. She leaned over and kissed me again French style. She didn't try to feed me any of my cum. She said that was how Martha said you prove it was all gone. I was thinking I might just love Martha too! Rene tried to describe how my cum tasted. She settled on sweetish and a little tangy too. Good enough for me. I  was looking forward to practicing for whenever she wanted to give up her pussy. I hoped it would be soon.  Rene told me that she kind of liked "doing that". I think I got a little over anxious and told her I would love to help her with practicing again anytime. She said maybe, but she didn't want to cheat on her boyfriend. I still haven't figured that out!
