Stripe Deposit (Upfront) Payment. Need to charge customer 2 months in advance

I have monthly subscription plan setup in Stripe. Creating subscription and charging is working for month by month, but I would like to charge customer 2 months in advance.

Example: user should be subscribed 6 months. I would like to charge him 1st month and last month (6th). So he won't be paying 6th month.

I was trying to charge customer once and then another time but it says that I can use stripe token only once.

How can I make this deposit payments in stripe and PHP?
