It depends. If the stories contain explicit sexual content intended for sexual arousal, it could be considered porn. But if they are more about romantic or sensual aspects, not necessarily.
Sensual descriptions play a big role. This could be in terms of the physical appearance of the characters, like 'her raven - black hair cascaded down her shoulders' or the setting, such as 'the dimly lit, velvet - draped room'. Also, the relationships in sexy English stories usually have an element of mystery or forbidden nature which adds to the allure. It could be a love that is not supposed to happen because of social status or other factors.
Well, first of all, the characters. They should be charming and attractive, like a dashing hero or a beautiful heroine. Second, the setting can be a bit mysterious or alluring, such as an old castle or a moonlit beach. And of course, the language used should be a bit suggestive or passionate. For example, using words like 'desire' or 'longing' in the right context.
There was a sexy English story about a mermaid. The mermaid had a very alluring voice. One day, a sailor heard her singing while his ship was sailing on the vast ocean. He was so attracted by the voice that he followed it. When he saw the mermaid, her beauty was beyond description. They tried to communicate in broken English. Eventually, they became friends and shared many interesting stories from their different worlds.
Many sexy English novels use language in a very evocative way. They might use words that create a sense of passion, longing, or desire. For instance, words that describe the look in someone's eyes or the touch of a hand in a sensual way.
Well, often they involve passionate relationships. For example, in 'Fifty Shades of Grey', the relationship between the two main characters is highly charged with sexual energy. The language used can be very descriptive of physical attraction and desire.
It's a rather unusual and potentially risqu茅 concept. Maybe it involves the alien's interactions and conflicts in the town while dealing with the unique dynamic of having fairy parents.
