Over the past few years, my relationship with my sister Barbara has become very close and I am very happy. Recently, I shared some comments about our open communication. My husband Jim didn't always like Barbara; in fact, shortly after we got married, he couldn't stand her. He said she was "self-centered and had no sex drive". So, if you have been reading my comments, you would know that she is no longer sex-deprived now, and Jim now quite likes her too. So, yes, Barbara has become more cheerful now, and most of the time she is almost as sexually active as I am. We also talk about sex-related topics.

Last weekend, Barbara went to see her mother's flight was delayed. We insisted that she stay with us. Actually, Jim had to work overtime until very late, so I and Barbara had a few hours of free time to talk about what we called "penis-related topics". Barbara was very curious about Jim and his attitude towards me. Our conversations usually involved discussing how to improve her sexual skills in bed, and listening to my suggestions. I always told her that learning oral sex skills was crucial for improving her overall sexual skills, and the better she learned, the more time her husband would spend making her happy and pampering her little hole. In other words, an act of retaliation. 😊

After drinking for nearly an hour and chatting about all kinds of naughty things, we heard the garage door creaking. Jim had arrived home. Both of us blushed; I knew very well that Jim must have realized that what we were discussing was much more than just the weather.

Sure enough, after putting his briefcase on the kitchen counter, he glanced at the island counter and said, "Wow, it seems that you two started the party before I arrived."

"All right, hurry up and find a comfortable place to join us," I said.

"It sounds quite interesting, dear," he said. "I need to take a bath and then go to bed. Today's work was too exhausting."

"No problem, dear. Go back to bed. I'll organize a private party for you." As I said this, I jumped up from the sofa and carried the wine glass to the sink. "Sister, relax, don't be stiff. Just like at home... If there's any noise, cover your ears." I added with a seductive smile.

While I was wiping Jim with a towel, I was particularly observing his increasingly erect body. At that moment, I felt a bit guilty because I had left Barbara in a desolate place. I knew that she knew what we were doing up there and would surely be very excited. However, I had tried this with her last year, so I hoped she was okay. Now she must understand that the needs of sisters are more important than those of a couple.

After we had sex for about twenty minutes, I heard a noise and quickly turned my head to look. I saw Barbara's face peeking out from the crack of the door, about to go to the guest room. She widened her eyes and saw me lying on the ground, with Jim standing at the foot of the bed. His thick and hard penis was going in and out of my mouth.

As I continued to serve him, I soon heard the faint sound of the vibrator starting up. Then came the pleasant whining sound.

Soon, Jim performed his signature move: he grabbed the back of my head and forcefully thrust his penis into my throat. His semen gushed out. This time, I couldn't help but gag; a large amount of semen rushed into my throat and mouth, and I simply couldn't control it.

We heard the gentle cries of Barbuda reaching their climax in the corridor, and we smiled at each other knowingly.

Usually, Jim would take a break for a while, then turn me over and perform the rear-entry position on me. But he said he was tired, so I let him rest. Later, when we talked about this, he admitted that although he found it exciting that Barbara got excited upon seeing us, he didn't want to share too much. I understand.

But this day provided a good foundation for my future conversations with Barb about sex.
