Without being too spoilerish with the Fate / Grand Order game, let’s say that in the present doujinshi’s setup, Mash isn’t living on a limited lifespan anymore, and thus she doesn’t need to repress her feelings and instincts anymore. Just like any normal young girl, she’s in love, she’s horny, and her beloved partner is available, so there’s no reason to hit the brakes =)
That could be the doujinshi’s theme: Mash’s liberated assertiveness, so to say ^^
Oh boy, I love Mash, and I love being taken by surprise by her hidden sides too. Honest to herself, not shy anymore, behaving like a teen girl eager to get more, more, MORE, she was, here too, adorable 
In terms of art, we’re way above average, even though the multiple bars censorship imposed a glass ceiling before I could throw even bigger compliments. Mash’s slutty sexy maid outfit was irresistible :3
Enjoy, my dear pervs, and many thanks to C722435! 
By the same artist, I also share Kyuuai Mental (“Romance Mental”, 203 pictures) and Kango X Raikou.
