Sibling Flirting or Exhibitionism - anyone experience or partake in?

[Hammer1949]

My wife stayed at her brothers for six nights and she told me that every night she would awaken at least once with her brother against her back and his hand cupping her breast. She told me a couple of times she could tell he was hard. The last night she was there she woke up laying on her back with her legs slightly spread and she told me his hand was on her pussy. She admitted that she was a little shocked and played there for a few minutes trying to figure out if he was awake or still asleep.
She told me that as she tried to move to get his hand off her he pressed a little harder and managed to get a finger inside and moved to try to hold her down. She said his cock was very hard and pressed against her leg. Finally as he tried to spread her legs further she yelled at him to stop and he acted as if he was asleep and didn't realize what he was doing.

He came to visit us a couple years later and as I was laying in bed and my wife was getting ready to get a shower he'd walked into the bedroom nude to get a towel to take a shower in the other bathroom. I was able to watch them talk to each other for several minutes as they were both nude.

To this day, I'm still unsure whether it was them flirting or just normal for them as she told me, but I used to live with a Spanish girl named Maria. Her brother, Martin, visited for about a week before Maria moved out of my place. Because we only had a 2-bedroom apartment, Martin slept in Maria's room during his stay.

The first morning after I woke up, I saw Maria making breakfast. I asked her if Martin was still asleep and she said yes. About 5-10 minutes later, he came out of her bedroom fully naked, gave her a morning hug and kiss. They always kissed on the lips, though never like making out kind of kiss. This happened a lot at night too. Martin would always take a shower before going to bed, and he'd never bother putting clothes on after that. So he'd be naked and gave Maria a good night hug and kiss.

Another story is when Maria asked how Martin's girlfriend was doing, and he said they were doing okay but she didn't want to have sex with him for the last month or so. Maria commented if that was because his dick was too big and it hurt his gf too much. He replied back saying she had seen his dick before and it was not super big that it'd hurt someone. She then said that she had never seen his dick hard though and that would make a huge difference.

There was also one time when he asked her why she was still single though she's hot. He continued on and on about how she's more beautiful than his gf, has better body, bigger boobs, nicer thighs, and so on. She countered back why he's saying his gf is not as good, and why he couldn't find someone better considering how handsome he is and all that.

They sounded normal but at the same time there were a lot of innuendos that could be considered as flirting.

I still remember getting pubic hair and lots of erections, some ending with spurts. I was proud of my new toy. My sister was 6 years older and had moved away to college.
We shared the upstairs bath with our grandmother.
I finished a bath and heard her arriving and yelling hello to grandma. I decided to let her see my new toy so I opened the bathroom door naked with a massive hard on, still drying off with a towel but making no effort to cover my nakedness. To my glee she stared at my cock. I was happy and with little action shot a load into the toilet.
The next morning I tried it again. She saw my hard cock and said “you have a nice penis for your age but I am your sister and don’t want to see it, especially with it erect. Go back into the toilet and do what you obviously need to do”. I did so.
After she left our Mom told me not to be naked with my sister. It makes girls nervous. Soon afterward she explained how sex worked.
