Sunstone, vol. 1, by Stjepan Sejić

Second frame of third page:

Lisa:
“It’s just my life… a story of how I changed.
And… the hardest thing is to start. Where do I even begin?”

First in a series of volumes about the loving and kinky relationship between Alison and Lisa, and Alison’s friend Alan who builds her equipment. Not especially explicit, but very sexy. You can get it here.
