**********
John and Alice have been married for three years. They lived in the same neighborhood with Alice's sister Mary. The two sisters usually chatted a lot. The two families were very close.
One day, Alice said to John, "Dear, my sister told me that she hasn't had sex with her husband for a long time. It seems that they are now living a sexless life. Will we be like that in the future?"
John laughed and said, "No, I will always be fascinated by you for the rest of my life. I like every inch of your body. I like the feeling of making love to you, especially your big butt. I'm not like your brother-in-law."
Although John answered Alice like this in his heart, he secretly paid attention to Mary. Several times when Mary accidentally exposed herself, John feasted his eyes. In John's mind, although Mary was a married woman who had given birth to children, and her figure was not very good (women who have given birth usually have bigger butts), Mary had a pair of breasts larger and softer than Alice's, and a butt that was more exciting to have sex with. Just thinking about having sex with his sister-in-law one day made John extremely excited. It also awakened the evil side in John's heart.
However, this could only remain in his heart. He really wanted to tell Alice that he had sexual urges and fantasies about her sister. He imagined that Alice would help him and persuade her sister. But that was just wishful thinking. He dared not act on it because he was afraid of being scolded and misunderstood by his wife, which would affect their married life. However, as the days went by, John's incestuous desire became stronger and stronger. He was just unsure whether Mary would accept such a relationship; whether Mary had such an urgent need for sex. If so, his hope would be even greater.
Finally, one day, by chance, Mary told John that she wanted to watch the animated movie "Howl's Moving Castle". John wondered if he had it. At that moment, John made a decision. He decided to take a chance and follow his desire.
John found a day when only Mary was at home and went to see her. He said, "Sis, I borrowed the cartoon you wanted to watch from my colleague. Do you want to watch it?"
"But we have to watch it on the computer. I haven't transferred and burned the files yet. Can I borrow your computer?" Mary said without doubting him.
"Sure," John said. He then led Mary to the study. In the study, John turned on the computer and installed the portable hard drive. He then said, "Sis, do you want to see it first?"
Mary said, "Okay! Anyway, I have nothing to do now. I don't have to open the store until 12 o'clock."
Little did Mary know that this was a trap set by John. He deliberately put a few adult videos in the portable hard drive to arouse Mary's hidden desire. After installing the portable hard drive, John opened the directory and said, "Oh, what's this? How come there are other files? I don't know what this is. Sis, do you want to see it together?"
Mary said, "Well, whatever."
John sneered secretly in his heart. He opened the file. The computer screen showed a scene of a man and woman having sex. The woman was sucking and licking the man's genitals. This scene had a great impact on Mary, who hadn't had sex for a long time. What's more, the person sitting next to her was her sister's husband. It felt so strange. John also secretly glanced at Mary a few times and found that Mary was staring straight at the computer screen without any intention of turning it off. He knew that his plan was gradually taking effect.
After a few minutes, John said to Mary, "Sis, do you want to continue watching? I want to go to the bathroom."
Mary also felt embarrassed about her loss of composure. She hurriedly said, "No, John. How could your colleague also put adult videos in it? Turn it off."
John said, "Wait a minute, Sis. I really need to go to the bathroom. I haven't gone for a long time."
So John said as he stood up and walked to the bathroom. As he passed by Mary, Mary glanced at John secretly and saw a big bulge in John's crotch. Her lower body twitched unconsciously.
John went into the bathroom and began his next plan. He pulled down his pants to his knees and made loud noises, pretending to fall.
"Ouch, it hurts so much," John shouted in the bathroom.
Mary heard John's cry of pain outside and knocked on the door anxiously, asking, "What's wrong, John?"
"Sis, I fell down. I can't stand up. It hurts so much," John said.
"What should we do then?" Mary said.
"Sis, can you come in and help me up?" John said.
"Me? It's not appropriate." Mary said.
"But Sis, I really can't stand up. Come in and help me up! It hurts so much."
"Alright."
Mary pushed open the door and found John sitting on the floor in a mess. But she also saw John's erection.
Mary thought, "Wow, so John's little brother is so magnificent. It must be at least 15 to 16 centimeters long. The glans is big and red. I wonder what it would feel like if it entered my little hole." But because of her restraint, she still said to John, "John, put on your pants first."
John said, "Sis, I can't stand up. How can I put on my pants? Help me up first."
So Mary helped John up. John then took the opportunity to pretend to accidentally touch Mary's breasts, further stimulating Mary. The two staggered to the sofa and sat down. As soon as they sat down, Mary asked John, "Are you okay? Do you need to see a doctor?"
John said, "It's okay. I'll rest for a while and see. If it doesn't get better, I'll go see a doctor myself later. But Sis, I'm sorry I accidentally touched your breasts just now."
Mary blushed suddenly at John's words. She hurriedly said, "It's okay. You didn't do it on purpose."
John thought the time was ripe, so he quickly moved his body and sat next to Mary. He said to Mary again, "Sister, your breasts are really soft. If I tell you that I deliberately did it just now, will you be angry?"
