You may access new sex scene by talking to Bella after the streaming to unlock park talk.
And also many existing scenes reworked into multiple variants with various sizes of Bella's pregnant belly:
You will be able to impregnate her, and even continue the story further from the hospital to visiting park together with Bella and an appropriate story. Later we will include an option to choose her destiny - one route, this one will lead to a family while second will focus on more on gaming and promiscuity activities.
We are even considering to add one more sex scene angle for Bella in the library as a part of fix update that will surely happen in a few days. And in general there is much more to show,
and our goal is to make more girls to have the pregnancy. We definitely want to progress main characters and give them one too :) 
 Next update will be about Judy
Which will happen quite soon as well (v0.25.20), because we have half of it already prepared, here is a small sneak peak:
Thank you absolute legends for your generous support, thanks to which we made this content and pushing the taboo limits forward. More info about next release very soon.
