[Tanunosuke] Young Shirou 2 (Fatestay night)

A nervous young schoolboy lies on a bed, his body slick with sweat as an older, muscular man looms over him, promising to finally insert his penis. The schoolboy protests his reluctance while the man teases his legs, his voice trembling with a mix of fear and excitement. The encounter escalates as the schoolboy’s resistance fades, leaving him overwhelmed yet oddly aroused.
