Haaa, that one was quite pleasant 
In Kanojo Face, two highschoolers make their relationship progress to the next stage, and at long last, the girl shows, in the midst of passion, her girlfriend face, huhu.
You won’t have super hardcore crude action, they’re first timers, and there’s a very strong, heart-warming vanilla vibe, there’s the thrill of discovery, the hesitations, the surprise to see “it works”, the joy of being with a loved one… Again, haaa, that was quite pleasant ^_^
Enjoy, folks! And many thanks to Hentai_Doctor 
By the same artist, I also share Houkago Étude and Yappari Kimi Ga Suki.
