Well, it varies a lot. Some wives might be shocked or uncomfortable with such a story, seeing it as vulgar. But others might have a more open mind and view it as just a fictional tale without getting too worked up about it.
There was a wife who lived near a small countryside village. One morning, while she was hanging out the laundry, a large cock came running into her yard. It was much bigger than the ones she had seen before. Its bright red comb and long tail feathers caught her eye immediately. She was amazed at how grand it looked as it strutted around, pecking at the ground and making its presence known.
Imagine a family decides to visit a heritage farm. There, the wife sees a large cock (rooster) that is part of an old breed. This rooster has a large body and a very distinct color pattern. It's also very friendly and comes right up to her. She's amazed by its size and beauty, and also by how it seems so unafraid compared to other smaller animals on the farm.
If 'big cock' is not referring to a rooster but rather some sort of large object or mechanism named 'cock' (although this is a bit of an odd and less common usage), then the reaction story could be about how people or things interact with it. For instance, if it's a large lever or knob (referred to as a 'cock' in some old - fashioned or very specific mechanical jargon), the story could be about how workers in a factory react when this large 'cock' is activated or adjusted, perhaps there are initial difficulties in getting used to it, or some unexpected outcomes due to its large size.
A healthy relationship story could be about a wife and husband who volunteer together in their community. They grow closer through helping others and sharing common values, which is much more positive than inappropriate topics.
A wife might find a big cock wandering into her yard one day. She decides to keep it for a while. She names it Sunny. Every day, she enjoys watching Sunny strut around and peck at the ground. One day, Sunny scares away a pesky fox that was trying to get into the chicken coop. The wife is so proud of her big cock friend.
Some wives could be a bit shocked or uncomfortable. For example, if she has more traditional values, a MMF story might go against what she believes is appropriate. She might feel it's too racy or not in line with her view of relationships.
She might be surprised at first. If it's a really large or unusual - looking water tap cock, she could mention it to her husband or friends just as an interesting observation.
I'm sorry, but I've never heard of this 'large cock multiple orgaasiums story' before. It could be a title that someone has made up randomly, or it could be part of a very specialized piece of literature or an oral tradition that is not widely known. There's just not enough information to accurately describe what it's about.
