Мужчина-мазохист, оставленный японскими девками

Two Japanese girls are playing with their smartphones. The masochist man is stripped naked and tied to an iron bar. A vibrator is attached to the masochist man's penis and the girls are constantly stimulating it automatically. The girls ignore the masochist man and continue playing with their smartphones, but when he is about to ejaculate they hold a cup against his penis to collect his sperm. The masochist man has been made to ejaculate automatically for hours, and the cup is filled with sperm. The masochist man suffers as his sperm is automatically collected until his balls are empty, and the girls smile at his suffering and go back to playing with their smartphones.
