I have three separate sites in the same content niche. One is the original site which is an info site, one is a blog started 3 years later, and the third site is a news and resource site links site that operates in the same niche.

Today, I woke up to find all three sites on page 1.

The sites are completely separate and have their own hand-written content so there's no duplication issue in this sense. Also, the sites do not attempt to boost each for ranking purposes. The news site and the blog link back to the original site, but "nofollow" is used each time to avoid any appearance of link manipulation. Essentially, each site is unique and makes it own distinct contribution to this content niche while, at the same time, avoiding duplication and not participating in a link network. Also, the sites have their own separate and distinct backlink profiles since, due to the differences between them, they tend to appeal to different groups.

So here's the paranoid question since I own all three sites: can you potentially be penalized in Google for being "too successful", for hogging too much space on page 1 of a serps?
