Kagura Mikazuchi and Mavis Vermilion are rubbing their pussies like this
External (Kagura down, Mavis up), both girls with sexy lingerie (boobs visible, Kagura must have stockings with suspender belt), facial expressions: the same of the girls of the image I've posted. Background: the same of the image I've posted (you can draw some posters about kagura and some other pillow or doll with her image on bed. there's also a second little panel in an angle with the pussies that are rubbing each other with a lot of fluid that is coming out from them. Title: "Fairy tactics, part 5"
ps. respect the boobs size of the girls like the manga/anime
