When I was about 35, I went through a long dry patch with my wife. We loved each other, but the sex just wasn't there. The kids took up all our time, and we would get to bed cranky and exhausted. We were both working too hard, and we both were putting on weight. Every night my wife would get in bed with her phone and I would go down to the living room, and for all the sex we were having I might as well have been single. And living at the south pole. By myself.
I began to get really horny and distracted. Not all the time, you understand, but some days every woman I would see would fill me with desire. I longed to eat pussy. I was desperate to grab and squeeze a woman's ass. Just making out seemed like water to a man crossing the desert. At my job, managing a restaurant, I had many young women who worked for me, and often my days and nights were spent in deep sexual frustration. I didn't every do anything. I wouldn't. It was doubly wrong. But oh my God how I wanted to. One of them even had a crush on me. She was 19 and I was her boss, and she used to flirt like crazy with me.
After a week of long shifts with her, I started to talk to my sister about her. How sexy this girl (I'll call her Denise) was, and how it was going to get me into trouble. My sister (I'll call her Susan) kept asking more questions, and before long, I had unburdened her with the whole story of my sexless sex life. My sister knew Denise from visiting the restaurant, and said that I must really be hard up. Gradually, I told her that my wife and I had only had sex twice in the last five years, and I didn't see how we were ever going to get started again. My sister listened and told me that it was okay to need sex, that everyone did, and that my wife should either have sex with me, or let me loose to have affairs. We talked for a long time, into the night, and when I finally stood up to go it was almost one in the morning. (Susan's husband was out of town.) Susan stood up and went to hug me good night. She kissed me on the lips, then kissed me again. I kissed her back.
We stood there in her living room kissing for a long time.
I wanted to go further, but I didn't.
After almost half an hour of kissing, I left.
When I got home, my wife was dead to the world. I couldn't sleep. I texted my sister. She was still up. We texted back and forth for a long time. It was obvious that we both really enjoyed it, and that she wouldn't have minded if I had gone further.
A couple weeks I had a shift that ended at eleven. I texted Susan, and she told me to come over. When I got there, only her car was in the driveway. She answered the door in her pajamas. Her husband was out of town again. We talked again about sex for an hour, and then I kissed her sitting right there on her couch. She kissed me back. I began to feel all around her body over her pajamas, and it was clear that she wasn't wearing anything under them. She began to get very excited, so I unbuttoned her pajama shirt and began licking and sucking her tits. A minute later, I pulled off her pajama pants and began fingering my sister's pussy. I started with one finger, and then went to two. I went back and forth between slow and fast, and soon she was cumming from my fingers. Immediately I had to have a taste of her cunt, so I kneeled in front of the couch and began licking her. I had forgotten how good pussy tasted. Soon, she was cumming again from my licking.
We pulled off all our clothes and rolled around on the couch for a while. Susan sucked my cock a little, and I ate her pussy again. Somehow I never wanted to fuck her, but we did just about everything else you can do. At one point my cock was deep in her mouth and her finger was in my asshole, and it felt fucking amazing. And then her tongue was deep in my ass. I couldn't have asked my wife to do that, but when my sister did it, I was as hard as I had ever been.
After she had cum a few times, we settled down to kiss and hug some more, and eventually I got dressed and left.
We talked on the phone a few times over the next few weeks, and about a month later my sister and I ended up over at my mother's house on a Monday afternoon. Right away, my mother sensed that something was different. We could both see her trying to work it out. She wondered if I had left my wife, or lost my job, or something that I was trying to hide from her. At one point, I was putting away some things in the yard for the fall, and my mom came out with a funny look on her face.
"Is it true what your sister said?" Mom asked. "You two are having sex?"
I confessed it, angry that Susan had told her. But of course, Susan hadn't ever told her. "What are you talking about?" Susan asked innocently.
But my mother said, "He already confessed the whole thing."
