You've been a very good guy this year and Santa wants to reward you by being on the naughty list, he sends a Sexy Elf who gives you instructions on how to masturbate while she rides her dildo and at the same time while she spanks her ass you must do the same with your cock, which makes it even hotter. As long as you follow the instructions on how to stroke your cock, the elf will let you cum in her little pussy at the end.
