My Sister And I Helping Each Other

First I should say my sister and I were not raised together. I was adopted out. My sister was kept by my birth mother. I did not know I had sisters until I was in college. The middle sister was 17 and my baby sister was 15. My baby sister was one of the most beautiful girls I had ever met in my entire life. Dark dark brown hair, shorter than me, very slender body, and a beautiful face.

Fast forward about 17 years.

I found my sister on Facebook. She had been going through some bad times. Both of her past 2 boyfriends were abusive to her. I asked if she would like to come live with me at my townhouse. She did. I booked a plane ticket for her and picked her up at the airport when she arrived. I gave her a huge hug and was very happy to see her. She had had 2 kids by this point and had much better curves. I took her home. I got her settled in and a blanket so she could sleep on my couch.

A day or two later we were sitting on the couch and she said she was very happy I helped her. She grabbed my face and kissed me like a lover. I was surprised but enjoyed every second of it. She paused for a minute said said out loud, "But you're my brother." Then she said, "Fuck it," and went back to kissing me. She was a great kisser. Lots of tongue. After we broke the kiss I just sat back and told her, "You are a great kisser."

Nothing too romantic happened over the next week or so. One night I heard her call me from my bedroom. She was laying back on the couch masturbating and asked me to help. She wanted me to suck on her breasts while she used her hand on her pussy. Well surely I was willing to help. I took her top off and both of her now, I think C cup breasts, were there. I made sure to lick her nipples gently and caress the breast my mouth was not on. It didn't feel that long before she came. Then after she was done, I sat up. She asked me if I wanted her to suck my dick. Do my ears deceive me? No, she was serious. There was no way I was going to turn down my gorgeous baby sister's mouth. I'd stroked myself off plenty of times after I met her thinking about giving and receiving oral with her.

We went up to my bedroom. I stripped off my jeans and underwear and laid back on the bed. My sister remained fully clothed. She put her hand on my cock and sucked once up. She said, "You can cum in my mouth. I'll swallow it all." I tell you if I was fully hard and even anywhere near cumming, I would have exploded right then. My sister went to work and gobbled up my cock. She never hesitated.

I think I may have lasted 5 minutes at the most. I told her when I was cumming and she didn't slow down at all. She did not miss a drop. She swallowed it all. After she stopped she said, "What have I done?" and walked off downstairs. I got dressed quickly to follow her. She asked me when I sat with her, "What are we now? Dating?" I can't remember how I responded.

I spoke to her briefly the next morning and said something along the lines of I know we both have needs. If you want us to help each other with those needs, I will. Of course, things progressed to me eating her pussy and us having sex. She was on birth control so no worries about pregnancy either.
