How do you saduce a girl?

If her sexual pleasure is BDSM (IF YOU DON'T KNOW ASK HER!). Seduce her by tying her up with anything you want (duct-tape, rope, chain, hand-cuff, etc.). Make sure her mouth is gagged with anything (ball-gag, cleave-gag, bit-gag, ring-gag, duct-tape gag, etc.). Some chicks who love BDSM like getting their mouths gagged. If the girl wishes you to blind fold her, do it as well. To make her feel comfortable tie her in bed or a couch. To make her feel more sexually pleased, put any vibrator (vibrating-dildo, pill vibrator, or plain vibrator, etc.). And if the girl likes it, she will be moaning sexually, and orgasm like if she never orgasmed.
