Mao Mashiro's fourth S1 exclusive release takes on the hugely popular First Massive Convulsion Special series. Her firm, perfectly shaped natural H-cup body cums and squirts nonstop, overflowing with pussy juice. Aphrodisiac oil, toys, and her male co-star's merciless piston thrusts leave her trembling and moaning through orgasm after orgasm. "I feel like I'm losing my mind!" Experiencing such overwhelming pleasure for the first time, she screams as climax fluid pours from her body and her uninhibited sexual side bursts fully awake.
