Several Different New Ideas *Updated*

Have a few different unrelated ideas here, some more elaborate than others.

"Mating Season"

This is a world similar to ours, with people that are mostly the same as in reality, but the human reproductive system worked out differently.

Rather than an individual monthly cycle, humanity has a mating season. Every adult woman in her fertile years is filled with an intense arousal. One that quickly becomes almost painful to ignore. They will look for a man, preferable on the younger or stronger side or otherwise powerful but if they are desperate just about anyone will do. The males get horny and desire to have as many women as they can, to father as many children as possible.

The sex is pleasurable and temporarily relieves their urges while it is happening. But their bodies won't let them stop until they have been impregnated. They will keep looking for guys until they are pregnant or the mating season passes. The season usually lasts 3 or 4 weeks in the late summer, so that in the spring hospitals are full of nearly the entire female population giving birth at the same time over a several week period. Sex can and does happen outside of the mating season, though it is less frequent or intense and there is zero chance of pregnancy. Men and women don't create the same sort of relationships, as no one is expected to tie themselves to one person.

I'm looking to start at the beginning of a new mating season, but possibly a longer term exploration of such a world as well. Covering multiple seasons and stuff between them. Breeding is the focus, but also some exploration of sex in general and how men and women look at each other in such a world. There are little or no kinks I wouldn't be willing to write, feel free to make suggestions. I might play one men or several and you could play one or more women (it might be interesting if at least one of them is in her first season that she goes into heat and has to figure out how to satisfy her new desire to breed). The pairs could be anything from co-workers, (adult) classmates, friends, customer/client, complete strangers or just about anything else, again feel free to make suggestions.  I could also consider a version with you playing men and me women.

"The Princess' Knight"

The basic story:  A somewhat masculine looking heroine saves the day.  Everyone assumes she is a feminine looking man, and she does not bother to correct them.  She saves the princess, who falls in love with the heroine as she is escorted back to the castle.  The usual cliche marriage arrangements are made by the king, only on the wedding night is the heroine's gender revealed (two options here, starting with the wedding night or with the rescue and the princess falling in love).  This idea would be more story heavy and potentially long term (the heroine is assumed to be a man partially because of her appearance and partially because it is one of things women aren't supposed to do.  The marriage goes through and she has to pretend to be a man, with only her new wife knowing the truth, how she adapts will be part of the story).  This one could have a little bit of MxF mixed in, especially when they wrestle with the question of how to produce an heir.  It is a sex heavy story, but also focused on maintaining the illusion, and gender roles.

My idea is to play the heroine, though I would play the princess instead if someone else really wanted to play the heroine.  In this case, with such a heavy FxF focus, I would prefer to play it a woman, though I would not rule out playing it with a man,  I'm open to considering some variation/suggestions if you have any.
