Android's blowjob is indeed meant to be quite fast, but not insanely so.The only animation I've seen which seemed to be to fast was the android blowjob one but I just thought that was intentional.
Runey Do you plan on making the side girls accessible without the main girls having to be in their rooms at some point?
Yeah, you'll be able to interact with them when their main girl counterpart is working/at school at some point, in some form at least.
