StepMom comes to pick you up from your friends house and she's not best pleased. You were meant to come home last night, not stay over. You're grounded. She doesn't care how old you are, while you're living under her roof, you have to do what she says. Just be glad she's not telling Stepdad or you'd be in even bigger trouble. Why did you stay out anyway, were there girls there? And what are you hiding in your jeans? Don't lie to her she saw it when you got in the car - have you stolen something? That is not just "you" under there, she can see something big. Show her right now! You awkwardly...

StepMom comes to pick you up from your friends house and she's not best pleased. You were meant to come home last night, not stay over. You're grounded. She doesn't care how old you are, while you're living under her roof, you have to do what she says. Just be glad she's not telling Stepdad or you'd be in even bigger trouble. Why did you stay out anyway, were there girls there? And what are you hiding in your jeans? Don't lie to her she saw it when you got in the car - have you stolen something? That is not just "you" under there, she can see something big. Show her right now! You awkwardly unzip your pants to reveal that it is in fact all you and Stepmom's face flushes with embarassment... and something else. She asks why you're hard and you admit it's because she's wearing a particularly low cut dress. StepMom apologises for making things awkward, but warns that you've got a long car ride ahead and she doesn't want you to be uncomfortable the whole way. Plus you can't let Stepdad see it, he'll definitely know there were girls at that party. Why don't you just relieve yourself? Stepmom promises not to look. When you tell her you feel too awkward, she takes matters into her own hands. You can't believe Stepmom's driving down the road, in public, in broad daylight with her hand wrapped around your cock! You're so turned on that you don't last long and cum in her hand. She's instantly regretful when she realises what she's done and makes a deal with you to mention neither the party nor the handjob to Stepdad. But you've got a better idea in mind. Behind her back, you take the SD card out of the dashcam which has recorded the whole incident, ready to use as leverage over Stepmom when you pull up in the driveway...
