LMAO! Not anytime this year, but that is a planned story arc for either a Brooke or Nicole update down the road.
Bonus points if you know which two 80's flicks that is a reference to.
There are no pregnant bellies or pregnant sex at the moment and won't be for a long time. Currently, the game gives Achievement style popups when you get a LI pregnant, but there are no visible effects as a result.
My research/polling shows that most players only care about pregnancy up to and including the moment of conception and don't really care about the stuff that happens after. Many players don't want pregnancy at all, so I have provided a Toggle in the Settings to turn Pregnancy Off.
Pregnant Bellies and Pregnant Sex are things that I would treat like an expansion pack. (Sims VI: Pregnant Bellies)
The mother has the most content by far. The sister has some really nice quests and one (vaginal) sex scene. There are two aunts which I'm currently developing. Aunt Irene has a BJ scene.
The "awkward, nerdy girl next door" character who MC has "friend zoned" is his cousin and many of their scenes create a lot of unresolved sexual tension.
I'm not the best person to assess this because I have an obvious bias. If I may self-assess: I think my dialogue writing is way better than my story writing, if that makes sense.
To take the mother/son story as an example, I tried to write an overworked and overextended single mother who has become exasperated at the notion that her adult son has accumulated little experience or interest in girls. In order to "jump start" his interest in girls, she decides to teach him how to kiss which kindles a mutual and ever-growing
desire lust for each other.
