Perhaps it's a rather unclear or misphrased statement. If we assume 'came in' as 'interrupted', it might be that you interrupted your little sister while she was narrating a story. This could have been accidental, like you didn't know she was in the middle of it, or maybe you were excited and wanted to add something to the story.
First, think about the setting. Was it a cozy living room with a warm fire? Or a sunny backyard? If it was in the living room, you can write something like this: 'I came in my little sister story on a chilly winter evening. The fire was crackling in the fireplace as my sister sat on the old rug, surrounded by her favorite stuffed animals. She looked up at me and began...' Expand on the emotions, the characters in her story, and how you interacted with the whole situation.
When a friend's sister comes to my house as a guest, you can directly say,"Welcome your sister to my house!" Or " I'm glad your sister can come to my house!" He was expressing his welcome and happiness to his friend and sister.
It could be about an event where the person entered the story related to their little sister and food. Maybe it was a time when they joined their sister in a cooking adventure or a meal - sharing experience.
In many cultures and social norms, such a situation can be considered taboo. However, in the context of sexual health and open communication, different people may have different views. Some might argue that any sexual act should be consensual and within the boundaries of a healthy relationship. But overall, it often goes against traditional values.
The first time I came to my sister's house, I told her about my feelings
This was the first time he had come to his sister's house, so he was a little uneasy. He did not know what would happen. But my sister and her family were very friendly and kind, making me feel warm and welcome. Although my sister and her sister are sometimes intimate in front of me, I know that this is only an intimate relationship between them. It won't affect our relationship. In my sister's house, I felt the warmth and happiness of home. I was very happy to be able to come here. This experience made me cherish and appreciate my sister's existence even more. It also made me look forward to spending more time with my sister in the future.
No, it's not ethical. Kissing your girlfriend's sister is a betrayal of your girlfriend's trust and goes against the norms of loyalty in a relationship.
I don't think it's a common experience to just casually talk about such an intimate and private situation. However, everyone's sexual experiences are different. Some might find it a part of their consensual and private sexual exploration within a relationship, but it's not something that should be shared without appropriate boundaries and respect for privacy.
They're not acceptable because it's a form of abuse and disrespect. No one should subject another person, especially a family member, to such a degrading act.
You can make a scrapbook filled with stories and pictures of her kind deeds. It can be a great way to preserve these memories and also show others. For instance, if she donated her toys to less fortunate children, write about her motivation and how happy the children were.
