Keeping secrets for my slutty step sister - Nina Nirvana

My step sister thought I would keep secrets from our parents if she sweet talked me enough. Well It was going to be a little more than sweet talk talk, it was going to have to be her sweet mouth. She offered to cook me breakfast. When she knew that wasn't going to work she showed me those perky little titties with dime size nipples. It was a good start. But I was going to need more if she wanted me to keep my mouth shut. She sweetened the pot with a hand job. I could feel my swollen cock and it seemed like a fair trade. Besides I could tell she had wanted this for a while.
