Your hot step-mom sits down on your bed, annoyed that she has been asked to tuck you into bed. She begrudgingly suggests a few things that might help you relax, then starts to loosen up when she comes up with the idea to instruct you as you jerk off so that you can finally relax and get to bed. She decides to straddle you instead and ride your cock to provide you with the ultimate relaxation. After you both cum, she leans back to let you see the creampie gift you've given her ;)
