[Dusuya-san (Dusu)] Kei-chan Kaihatsu Keikaku! (Blue Archive) [SCANMTL]

Kei Tendou’s “Kaihatsu Keikaku!” pairs her shy, teasing resistance with Sensei in a charged Blue Archive fantasy, foregrounding her long hair, horned catgirl design, generous breasts, school uniform, stockings, and the tail plug waiting at the story’s center. The dialogue moves from “You... okay? Did you lose your nerve?” to breathless claims about tightness, lost control, and being overwhelmed, turning intimate experimentation with toys into a deliberately excessive sensory escalation. The closing afterword, including a “LATER” gag about collecting samples and the publisher’s colophon, gives the whole book a mischievous comic edge.
