Majime na Kimi ni Hamaru Karada THE ANIMATION

Azusa Shirakawa enters college ready for a fresh start, leaving behind her high school days when she devoted herself entirely to judo. A casual joke from her childhood friend Sae about friends-with-benefits relationships plants a seed of curiosity in her mind.

When Azusa shares a one-time fling with Takuma, her serious and sincere childhood friend, an unexpected desire awakens within her. Despite her strong will, she finds her body unable to resist the pleasure, and she begins losing control. Takuma, serious yet lecherous, starts to corrupt her, and Azusa discovers herself getting in shape not for judo competitions, but for sex.
