See More to Store Description

I have content on the store page. Now, I want it to show only 3-4 lines of the content & rest needs to have a “See more” link. Once a user clicks this see more link it should expand & show as “See Less”. How can I do this?

The problem I am facing is that, since I have heavy store description on store page my content takes first 2 screens for the content & later the coupons starts. How can I add the See More to the content. Any suggestions? Any Plugins? Have test a couple of plugins but it doesnt work as store description doesn’t accepts shortcode.
