Background of the story:

Your rent is due and you are currently staying at your stepbrother's house until you can find your next place to stay. Today is your birthday and you've asked your boyfriend out on what you hope will be the perfect birthday date. Although you had prepared for the date and even planned to spend the night out, it didn't go as well as you had hoped, and you returned home early in the evening, frustrated. And just as you enter the door you realize that your workaholic brother, who left the house early in the morning and said he had to work overtime today and couldn't accompany you on your birthday, has arrived home. There seems to be a big piece of cake and a small gift box on the table ......

Characters Basic Setting:

Listener: Female, 20s, Some degree of insomnia and anxiety over the past year or so, voice-fetish, hands-fetish, undergoing orthodontic treatment (invisible braces)

Speaker: Male, about 3-4 years older than Listener, seems to be a workaholic and not very talkative, but in fact he is just not good at showing his feelings and is not used to it.

Overall requirements:

I need Speaker to present a kind of tenderness and care in this whole story that he is trying his best to restrain under the intertwining of his own strong jealousy, possessiveness, guilt, and repressed desires. At the same time, I want Speaker to show that his jealousy, possessiveness, and guilt are gradual, not immediate and intense, but incremental, and ultimately explosive.

In my scenario, Speaker starts out very calm, normal or just slightly jealous, and probably even taunts the listener in a flirtatious tone, and after learning that the listener has failed the date and hasn't done anything all day, Speaker sounds like he's in a noticeably more relaxed and better mood.

But as their conversation progresses, Speaker is gradually drawn out by Listener, and the words that have never been spoken are finally able to be said to the right person: feeling unworthy of what she's given herself, sad that she's never seen himself, angry that she doesn't believe in his own feelings, revealing to her his own fatigue and struggle to maintain his sibling relationship for so many years, and so forth. And, of course, being happy for her joy. Eventually, when a certain tipping point is reached, Speaker's sanity can no longer suppress his raging feelings and desires.

At the same time this tendency, I would like to see reflected in the lovemaking between the two of them (erotic, sensual but not pornographic maybe?).

Focus:

Because this is the first formal and complete sexual experience for the listener, the Speaker must demonstrate a sense of caution, for example, when the Speaker is exploring the listener's body and sensitive spots (here the Speaker needs to appear to be very exploratory), but also fear that the listener will get hurt or make her uncomfortable. (It's okay to use some lubricant during the process). After all, the Speaker wants to give the listener the best experience and memories possible while keeping both partners satisfied.

(During the process, the listener will discover that the speaker is unexpectedly skilled at dirty talk and praising .Of course, she will also unexpectedly discover some of her own hidden kinks.)
