My sister in law came to visit us was looking good. We have flirted a lot since I’ve been with my wife, she would always tell me about what she likes a guy to do to her, and was very touchy with me. She took my hand before, and placed it in her pants and on her ass. She laughed and asked how it felt when she did it. My wife had to go to work, and it was just me and her sister in the apartment. her sister said she was going to change into her bathing suit and head down to the pool. The room she was staying in was right next to a bathroom. I got up and walked to the bathroom, and noticed the door was slightly open. I looked and there is my sister in law completely nude, and bending down to get her swimsuit out her suitcase. Her pubes come in splotchy, so she is always completely shaved, and her tits were looking so good.
I went to the bathroom when she stood up, and when I came out she was in her suit. Her cleavage looked amazing and her pussy was barely covered in this one piece. She asked if I wanted to come down, but wanting to jerk off to what I had just seen I said no. She begged me to come, so she wasn’t alone, so I said I would. I changed into my trunks and we went to the pool. The water made her nipples poke out, and I knew the world was testing me. We swam and had fun, and then she got out to lay in the sun. She asked if I would keep an eye out because she was going to lower her top so she didn’t have lines. I just kept hoping she would turn over not thinking and I would get another glimpse of her tits. We ended up staying down there for an hour, and made our way back up to my apartment.
I told her I was going to jump in the shower, and she said she was doing the same. I thought, what if she wanted to shower together, but she went to her bathroom and me to mine. I was in the shower, when I heard the cabinet open, and I thought my wife was home early. I said hello, and the voice that responded was not my wife, but her sister. She said she was just grabbing the hair dryer, and then said, “are you jerking off in there?” I said no, and she said, “well was seeing me naked not enough to get you off?” I turned the shower off, and said, “what are you talking about?” She responded that she saw me sneaking away, and that it was ok, she hoped I enjoyed the sight. She ripped the curtain open, and said, “now let me see you.” I covered my dick, and she grabbed my hand and said no fair.
She grabbed me my towel, and i thought she was leaving, but she sat on the bed. “Cmon and give me a show, you know you’ve wanted this for a while. Remember that dream you told me about, this could be the first step.” I had a dream a few years before, where my wife and her were fucking me together and I had drunkingly told them about it. She sat on the edge of the bed, opened her towel and then opened mine. She grabbed my dick and stroked it. “Cmon, don’t be afraid, I won’t bite.” And she took my cock in her mouth. Her mouth felt so good, and I placed my hands on her head and guided it back and forth. She would take it out of her mouth, and lick from my balls, to the shaft, to the head. It was driving me crazy how good it was. I pulled my cock out and pushed her down. I spread her legs and started eating her pussy. She was moaning so loud, and after a few minutes, told me she needed me to fuck her. I moved up and shoved my cock into her. We fucked in a bunch of different positions before I knew I was cumming. She locked her legs around me, and I came right into her pussy. She was so happy, and kept smiling at me. We laid in bed for a few minutes, before we got dressed and sat on the couch until my wife got home.
