継母のおっぱいに撫でる

You are stuck sharing a bed with your stepmom, Ellie, in a hotel room while your home is treated for mold, and you aren't sure about the situation.  However, since this is the only room available at the hotel, your stepmom tells you just to make do until everyone can go home.  Since your stepmom is reading and not paying attention, you decide to jerk off a little to help you relax for the night.  You pull the covers down to look at your stepmom's tight ass while you stroke, and she catches you taking a peek.  She sees you struggling to get off, so your stepmom decides to give you a little jerk off instruction session since you are sharing a bed in a hotel, and no one needs to ever know, especially stepdad.  Your stepmom pulls up her shirt to reveal her big fake tits so you can stroke to them, and she tells you just how to stroke so you can cum all over those titties.  NOW you can relax for the night!
