【Serious shop】FGO no Ehon 4 Marshmashimashi

I’m a master at having erotic sex with servants.
I don’t know why they won’t touch Marsh.

There is a reason for this.

Once you’re sexually involved, you’re Marshmallowed!
This is a great way to get to know the people in your area.

There is a connection with FGO’s erobooks 1-3, but it is also good on its own.
