Im your step daughter and im working on my anatomy final. I tell you im doing a project on dick size- is bigger better, and is bbc bigger than white dicks? When talking to you about it i can see you have an erection. I ask if youll be a part of my project and if i can measure it. You agree and i go get my ruler, take out your dick and it measures 8 inches. Wow thats big! I give you a handjob to keep you hard and i look up bbc on google to see how it compares, they’re all really big but you can definitely compete. I ask you to cum on my face as i give you a handjob and you do(:
