"Call me Dina, you know that," she chided. "This whole 'sis' shit gets on my nerves."
"My bad, Dina," I said to her, smiling. She stopped to bend over to pick up her receipt which had fallen out of one of her bags, and I found myself staring at her round little ass. I couldn't help it, seeing her naked had turned me on; I couldn't quit picturing it in my mind. I wished silently that she LIKED to get naked, and LIKED for me to see her naked.
"That's better," she replied, smiling at me again. She paused for a moment, "You know...I have to admit, I'm feeling kind of hot right now," she said, a devilish grin on her face. Without another word, she began to peel off her clothing until she stood naked in front of me, making sure she had my FULL attention.
"You like what you see, Joey?" she asked, her nipples erect, a half-smile on her face.
"Uhhh....yeah," I stammered. It was odd, examining my sister's body like this. Part of me felt like a pervert for making the wish, the rest of me felt strangely fulfilled. I could feel myself growing aroused, and so I shifted my weight uncomfortably, trying to hide it.
Dina laughed. "What's the matter, Joey? Am I turning you on?" She stepped closer to me, sliding a finger down to her clit, rubbing it lightly. "Hmmmm, Joey? Am I turning you on?" she whisper-moaned at me.
"Yeah," I replied to her, unable to hide the throbbing erection in my pants.
"Answer me a question, Joey. Have you been with a woman before?" She asked, being quite firm.
