Slim and cute beauty Saeki Eri-chan challenges 180 minutes of relentless continuous internal ejaculation! Men appear one after another, not just double fellatio but triple penises closing in. Stimulated by a vibrator on her clitoris, penises are repeatedly thrust into both her vagina and mouth, culminating in a series of continuous internal ejaculations from high-speed piston-like positions! At first, she seemed so relaxed that she occasionally smiled, but towards the end, Eri-chan was truly exhausted.
