You're having a family get together and everyone is going to the lake to swim, your niece comes upstairs to ask you if you want to come swimming with her. She starts pouting when you say you don't want to go and she tries to entice you by showing off her cute new swimsuit. She gradually starts to seem more and more like she's coming onto you until its obvious. She talks about how she has always wanted to be with an older man, but she's never gotten the chance. Eventually she notices that you have a boner and that you must be into her teasing, so she convinces you to show her your cock and even let her touch it. One thing leads to another and she ends up giving you a nice deepthroat BJ and jerking you off until you cum a huge load right in her hand.
