These are two students from Strawberry Panic's St. Spica school. To keep the explanation simple for those who are unfamiliar with the original work, it's a story set in a campus with three different schools at which futanari girls with more youthful energy than they can manage exchange body fluids with one another. Where the anime and manga held back, the original work features a heaping amount of lesbian intimacy. The number of liters of semen that flow each day is anybody's guess. Speculative discussions aside, I've taken a personal liking to the composition. I find its depictions more erotic than heartwarming. After experiencing them, I burn like nothing else for the face of a futanari girl ejaculating as she's receiving fellatio. Am I the only one?
