[SGPT (Shiogochi)] Stick It on Hiro's Flat Butt (Big Hero 6) {Chin²}

Hiro lies sprawled on his stomach, his bare butt prominently displayed with a pinworm test kit stuck to it as his brother Tadashi leans in, teasing the itch and urging a kiss. Their playful, incestuous banter escalates with jokes about urinalysis, leaks, and a sudden boner that makes Hiro protest, while the scene shifts to close‑up shots of hands probing and rubbing the sensitive area. The teasing, bodily focus and rising tension set the stage for a comedic, erotic encounter between the two brothers.
