[bibimbap (kazukoto)] XX-san wa Asobitai! (Fate/Grand Order)

Mysterious Heroine XX corners her Master with a pointed question about whether he's ever fooled around with any of his Servants, and when he stammers through a flustered denial, she gleefully concludes that a herbivore like him just needs the girl to make the first move. She takes full command from there, wrapping his cock between her enormous breasts and inviting him to let everything out before pulling him into a deep, breathless ride where neither of them can hold back. A playful, sun-soaked one-on-one where the teasing Servant sets the pace and her overwhelmed Master happily surrenders to her.
