A well-used paralytic machine

These depraved get into the train wagon and paralyze all the women, put them in position and choose which one they fuck. Once with the cock inside they de-paralize only the one being fucked, so they can feel the girl move. The girls, completely confused and with no way out of the situation, endure strong penetrations while they can't help but get horny. Once their pussies are full of semen, they paralyze her again, so they don't bother.
