(C89) [AquaDrop (Mikami Mika)] Ohayou Sex Bangaihen

A bashful younger sister and her casually domineering older brother turn an awkward morning into a tense first sexual encounter, beginning with fumbling condom talk and her protests that he is being too mean. The monochrome pages linger on her blush, averted gaze, trembling hands, and unsteady composure as he takes control, culminating in her breathless declaration, “First, the first round…” A closing note from Mikami Sanriki calls it “Ohayou Sex Bangaihen,” jokes about the sex scene being left unfinished, and teases a future story about the siblings at a love hotel.
