I go into my step-sons room to collect his dirty laundry and I find a vibrator in the pocket of his jeans. I ask him why he has a girls sex toy in the pocket of his pants and he tells me he stole it from a girl at school. I take the vibrator from him. Later that day, I’m in my room and I become curious on how this vibrator performs. I give it a good wash and then I turn it on to see how's powerful it is. It’s pretty impressive, but the only sure way to know how good it is, is to try it out on myself. I begin playing with my pussy and the toy really gets me going. I’m just about to cum when my step-sons comes walking into my bedroom. He sees me enjoying the vibrator and he tries to get involved. I refuse him at first, but I eventually decide I could teach him a few things about sex. I ride his cock and I let him fuck me doggystyle until he fills step-mommy up with his cum!
