Wanna Explore My Body Stepbro?

You are about to head to the gym when your stepsister Anna wants to do something with you since she is so bored. She wants to play little kissing game and have some fun with you. You are not too sure about all this at first. When she sits on your lap and starts to make out with you, you cant help but get a hard on. She can feel it and wants to see it. She would let you do anything you want with it. What should you do? Let her give you a handjob? Maybe even a blowjob?
