What luck I had. My parents were both called out of town by their respective jobs for the whole week. My mother, a lawyer, had to fly to New York to meet a very important client, and my father, an advertising executive, was called to Atlanta to attend a meeting. It just happens to be that this same week is my first week off of school for summer vacation. I would have the entire house to myself to do whatever I want, whenever I want. My sister, Desirre, (or Dez, as we called her) is away at college across state.
Monday morning rolled around rather quickly. My mother woke me up to tell me that they were leaving in the taxi soon. I got dressed and watched them out of the door. As soon as the taxi was out of sight, I slammed the door and made my way back upstairs. I went into Dez's room and straight to her dresser. When she had left for college, mom and dad bought her a totally new wardrobe, so she left her old ones at home. I wasn't uncommon for me to come into her room and use a pair of her panties to jack off into. I have had a panty fetish for as long as I could remember, and the fact that they were my sister's made the fetish even stronger.
My sister and I had always had a very good relationship. We never fought like normal brothers and sisters, something uncommon for kids these days. We are only eleven months apart in age, so we grew up as friends. We told each other everything, from details about our other friends to our sex lives. Nothing between us had ever become sexual, somehow.
Looking into her panty drawer, I noticed thongs and G-strings in every color of the rainbow. Dez hated bikini and granny panties for some reason. I pulled out a red thong and took my normal spot on her bed. I pulled out my cock and began to jack off, with Dez's thong covering my dick. I rubbed my cock up and down, faster and faster. My breathing got heavy as the pleasure began to overtake me. Moments later, I came all over the red thong, soaking it. After calming down, I threw the thong under the bed with the others that I had used recently. I walked downstairs to get something to eat for breakfast. I looked in the fridge, but we didn't have anything good.
"Nothing good to eat?" I heard. The voice startled me.
"Dez?" I asked. "How are you, girl?"
"Good" She replied. "Where are mom and dad?"
"They're out of town." I replied. "What are you doing home?"
"Just a little visit for the week." She said. "Guess it's just me and you."
"Yeah, they won't be back until Sunday." I replied.
"Damn, I have to leave Friday." She said. "Well, can you give me a hand with my bags."
"Sure" I said.
I followed Dez out to her car, which was jampacked with bags. After a couple of trips, we had most of the bags in the house. The last load was her laundry basket, which I grabbed. Right on top of the pile was a dirty, baby blue G-string. I looked over at Dez to see if she was looking. She wasn't, so I slipped the G-string into my pocket for later.
After getting all of her bags up to her room, Dez and I sat on the couch to catch up on old times. We talked for hours about what had been happening in our lives while we were apart. She filled me in on the guys she was sleeping with and I told her about the girls I had slept with. After talking and joking around for three hours, Dez decided to get a shower since the ride home was so long. She headed up to her room while I stayed downstairs. Moments later, I heard the shower kick on, so I knew I had at least thirty to forty-five minutes free.
I quickly pulled out the baby blue G-string that I had taken earlier. I lifted it up to my nose and inhaled, smelling the sweet mix of piss and cum. Like earlier, I jacked off into the G-string, spilling my load all over it. After I finished, I stuffed the G-string into my pocket, just as Dez was walking down the stairs. She was wearing a pink spaghetti string tanktop and a pair of pink boy shorts. She looked stunning. When she sat down, her pink thong became exposed.
"Derrick, can I ask you something?" she asked.
"Yeah, what?" I asked.
"You have a normal sex life right?"
"Yes, why."
"Because I dropped one of my earrings up my bed..." She started. I knew I was dead. " Why do you do it?"
"Do w-what?" I stumbled.
