You're visiting your female cousin along with your parents, and even though you jacked off twice before your parents drove over, you're still horny when you get there. There's just something about family gettogethers that make you so restless and turned on! So when you think you've got a few moments to yourself, you sneak in your cousin's room and start stroking. You're so distracted you don't hear the footsteps outside the door, and suddenly, there's your cousin, staring at your hard cock. She's never seen one before, and she's giggling, blushing, acting embarrassed and curious at the same time. But she promises she won't tell anyone, and when she asks if you want to stay for a sleepover in her room, you agree.
