[Yukimi] Katagiri Sisters

Sisters Tsugumi and Midori Katagiri treat their classmates like a shared playground—busty Midori gleefully riding her favorite, Ken, while her petite sibling takes on Daijirou nearby—until curiosity sparks a full partner swap so each girl can taste what the other loves. Between pudding bribes, teasing size comparisons, and strict ground rules about who gets to finish where, the two trade boys in a sweaty tangle of thick thighs, heavy breasts, and greedy demands for more. When uniforms go back on, though, Tsugumi drops the act and confesses her real feelings, pushing Ken and Midori toward something honest while proudly calling her sister a slut who never tells a lie.
