Intelligent and highly sex-driven female college student Riho Shishido is placed under a strict one-month abstinence order—no masturbation, no sex, allowing her sexual desire to build intensely. As she reaches her breaking point, filming begins, but penetration is still forbidden. The prolonged teasing amplifies her craving for penetration until her mental restraints completely shatter. Even light friction triggers a powerful squirting orgasm. Her engorged nipples become as sensitive as her clitoris, sending her brain into sensory overload with unprecedented pleasure. Finally, relentless pounding by a massive cock pushes her past the edge, culminating in a mind-blowing, explosive climax.
