I'm not going to be Nina longer thanwe need."------------------It was late afternoon when I heard the front door opening. I sneaked apeek from my room...s door and saw my sister walking in. Crap.I retreated back in my room but it was too late. The door slammed openas an upset Darcy walked inside."Oh, you're male again," she noticed in disappointment."Hey, you're smart!" I replied."OK, you had your fun, now tell me where did that thing at the mallcome from!" What are you talking about?" I asked,. I couldn’t help but think about the previous night’s activities. My cock got hard thinking about Fernanda. I gripped it in my hand and gave it several tugs. Then, suddenly, I realized I was not alone in the apartment. I froze. “Do you need some help in there?” Fernanda called out. I poked my head out from behind the shower curtain. Fernanda was standing in the doorway of the bathroom. “I thought you were gone for the day,” I said. “Are you kidding me?” Fernanda responded. “Do you think I. She found that very admirable and attractive about me. I was so glad to see her, even though we had just met a few weeks ago. When we talked, the time just flew by, and it seemed like there wasn't enough time in the day. After some time, our conversation got sexually charged. We just couldn't resist each other. The sexual chemistry was there and we both knew it. She told me that she loved how naughy and kinky I was. That she never had a man be so attentive and passionate toward her most. She never wears underwear! Since she was wearing a short skirt I noticed a few guys check her out more than once. I couldn’t blame them; she looked so fricken hot! I was so turned on I could hardly wait to get back to the tree house. The sun was down and it was pitch black when we got back. We lit a candle and sat on the deck of the tree house which was two stories up. She was sitting between my legs with her back to me, I started grinding my hard cock on her ass again. She must have still.
