Have a partner who wants to impregnate you in 2-D or 3-D, or who wants to defile you and use you as their toy as much as they want.
Want to impregnate someone quickly without going around and getting them pregnant.
On top of that, if you have a lot of such partners, you can redo only Shiva’s bio-laboratory data in the middle of the process.
If you have a lot of such targets, you can try to impregnate a different partner from the beginning.

Interesting. This one actually gives a download for “Semen Transfer Project” instead. I feel like it’s the wrong game, and the game has been posted in this site before, as well.
It is an expansion for it as well as the updated version.
For the expansion run AddContentsTensou.exe
You need to increase the amount of births enough to use it
I seemed to have completed the game already but can’t access the expansion?
I already gave birth to 35 children and have already unlocked the 2 Touhou Characters.
The option Shiva Institute option is still greyed out.
You are halfway
Conditions for releasing Shiva’s biological laboratory → Released when the number of body births reaches 70 or more.
