[Furafura Toxin (Arano Oki)] At Least Until This Rain Stops (Touhou Project) [Kaiser Comics]

Caught in a downpour with nowhere else to turn, a silver-haired wanderer ducks into a quiet shrine and finds Imaizumi Kagerou waiting — a languid, long-haired wolf-eared woman who seems almost too pleased to have company. Dripping wet and sharing a too-small bath for warmth, the night blurs into a slow, teasing seduction as Kagerou's ample, heavy breasts press against his back, her voice a low murmur about watching over him and consequences she'd face for dragging a stranger home. What follows is a breathless, dripping encounter filled with her flushed confessions — that his semen is "thick," that she's never felt it inside her before, that becoming a real adult feels embarrassingly overwhelming — and his eager, startled reactions as she squirms and shudders through her first climax before pulling him close for more. The story climaxes in a frantic mating press that leaves both of them twitching and trembling, her desperate cries of "Onee-chan!" ringing out as he fills her completely, the steam of the bath and the pour of rain outside blurring together into one long, indulgent night. By the end, even she isn't sure whether this fleeting refuge has earned her real adulthood or just a whole lot of trouble — and neither will the reader be able to put it down without finding out.
