[Marusyamo] Modified by my Kouhai 2

A towering rabbit-eared kouhai catches her senpai off guard, shrinking him to 10 centimeters and five grams before pressing his naked body into her slick armpit. Her 1,000% armpit obsession turns him into a helpless source of twitching, repeated orgasm, and breathless moaning, while a ruthless new rule forces his thoughts straight out of his mouth. With her heavy breasts, soft belly, and powerful thighs looming over every helpless movement, her promise to “play” with him whenever he asks leaves their deliciously unequal power dynamic wide open.
