My cock was getting harder and harder. When Skai came out in a short black skirt that showed off her thighs I was so hard she noticed and smiled. She bought the skirt and wore it out of the store. As we were driving away Skai asked "I saw you get hard. Did I excite you, Jim?" My face grew hot. "Well, ummm, I..." "It's all right," Skai smiled. "I think you're cute and I like that I excite you." "How do you know me being hard means you excite me?" I asked cautiously. Skai giggled. "I've seen mom fool around fool around with one of her boyfriends from time-to-time when she thought I was in bed. They'd fool around in the living room and when he's take his thing out it'd be hard like yours. But yours looks bigger." I didn't say anything in reply, I just drove. "Can I see it, Jim?" Skai asked. I nearly crashed the limo. "What?!?" "Can I see your thing?" She asked again. "Please?"
