My younger cousin gives me a handjob and swallows my semen while keeping it a secret from our parents

My younger cousin is a pretty hot chick, and she's always been into me. I mean, we're family, but she's always been the kind of girl who likes to keep things on the down-low when it comes to our parents. But, when she came over to my place the other day, she decided to put her plan into action. She was totally into getting down and dirty with me. And let's just say, she's got some serious skills. She went down on me like a pro, giving me the best blowjob I've ever had. And when she took me in her mouth, she didn't stop until she had swallowed every last drop of my cum. It was a pretty wild experience, and I have to say, I'm pretty excited about what's to come.
