Thank you for your detailed feedback.
Some of the rumours/gossip are things I plan to add but haven't managed to do so yet. Most should be added in the 3.x updates.
The sex events happening on their own was my attempt at having Sammy take autonomous actions based on her stats/horny/drunk levels. It has been a fairly divisive feature so in the updates I have toned it back a bit and kept Sammy acting on her own only for when her stats reach more extreme levels.
Dani is probably the most popular character so she in the updates has quite a lot of new stuff added to her. Over time she will become quite a prominent character. People also quite like Rachel so some new stuff is planned with her as well.
Bus stuff is planned :)
