Training My Homie's Step Sis & Creampieing Her!

Yesterday I was supposed to start training my best friend's stepsister at the gym but she texted me last minute saying to come meet her at their house instead. When I got there Lana was just chilling on her bed while her stepbrother was out on a date with his girlfriend. I wasn't sure why she told me to meet there given her room is so small there's no room to workout. She then told me that she wanted to do some cardio with me lol. Before I knew it she was sucking on my cock. As any good personal trainer would do I made the best out of it...
