I accidentally caught a glimpse of my mother‑in‑law changing. Worried about middle‑age weight gain, she was wearing tight corrective underwear that strained so much her impressive breasts looked like they might burst out. Her body — so lewd compared with her usual demure self — made me swallow hard. I couldn't afford to cross the line and tried to force myself to forget, but the repeated image of her changing was unbearable and I couldn't hold back — I ended up attacking my mother‑in‑law.
