I am generally not a fan of sex machine videos because they are so sterile without a bed or pretty room to fuck in. It seems fake or lacking in sensuality between the girls. Using sex machines would work better in a porn video with the girls facing each other tongue kissing and making love at first. This would be especially hot if they are captured in a demonically lustful state, wrapping their arms around each other while tongue kissing, licking their lips and faces, finally screaming with sexual ecstasy staring at their pretty girlfriend's face while cumming.
