[Shiitake Koubou (Shiitake Taishi)] Ane ga Ore to H Suru Tame ni Onnanoko o Tsuretekuru | My Sister Brought a Girl Over to Sleep With Me

A brother finds himself at the center of a charged bedroom setup when his sister brings a brazen newcomer over for the night; the school-uniformed curves, ample breasts, broad hips, and heavy thighs make every hesitant introduction feel like a dare. The newcomer’s boldness outpaces the brother’s stammering uncertainty as the sister and guest kiss, compare themselves, and pull him into a rough three-way escalation of oral attention, breast play, swapped release, and creampie. The brisk multipanel rhythm turns the forbidden sibling setup into a mischievous, competitive romp, while the closing credit page jokes about the redraw, typesetting, and translation.
