[Naruse] Kyoudai Change! ~ Kawaii Imouto no Karada ga Erosugite Yabai 1-6 [MTL]

After a sudden gender swap, the sister finds herself trapped in a male body, her shock giving way to conflicted pleasure as she is forced into intimate contact. She protests that she is a man while the panels depict her overwhelmed reactions and a forced oral act that feels strange. The tension escalates when another character, Mizuho, toys with her, leaving her caught between resistance and erotic submission.
