You're up north with your family at the family cabin, it's been a week so far and you're already feeling antsy. You and your cousin have always had sort of a flirty back and forth so you start thinking... You sneak into her room at night while everyone else is in bed and tell her that you can't go to bed because you're super horny, and have a raging boner that just won't go away. At first she's not into it, teasing you and calling you a perv. She tells you to get lost and go take care of your "problem" elsewhere so she can go back to bed. She slowly seems to get into it, showing you her tits and ass to help you out. Once she sees how big and hard your cock is she starts to admit that she's pretty horny too... maybe you guys can just masturbate together. Not a big deal right? One thing leads to another until eventually she's sucking and fucking your big cock until you cum all over her tits.
