It was the first hot day of the year. I wiped my brow with the sleeve of my T shirt as I pedaled my bicycle down the street. High school had let out for summer last week and it was an odd feeling to no longer be tied down by school. I was finally 18. I could do anything I wanted...which just meant that I spent the afternoon playing videogames with my buddy, Jason. Oh well. That's what summer is for. I banked my bicycle into my street and immediately noticed the green VW Golf parked in the driveway.
Erica is home, I thought.
Erica is my older sister. We are Irish twins. She is only 13 months older than me. My parents really wanted to get child bearing over with in as short a period as possible, haha. We had been fairly close growing up. Not in a creepy sort of way or anything. It is just that we both shared a good deal with each other and actually enjoyed spending time with each other, unlike other siblings our age.
I opened the door and called out "Erica? You home?"
"Hiya!" I heard a voice from the kitchen. I dropped my backpack on the counter and gave her a nice warm hug. "Are you here for the weekend?" I asked. "You know that mom and dad are away this weekend, right?"
"Oh! I didn't realize that." she said, stopping to think about it. "Well, it'll still be fun to hang out with my favorite brother!" she said. "I had such a busy last week of college. Those finals really kicked my ass and I need to recuperate," she said.
"Well, I'm planning to veg out and watch a movie later with some pizza. You're welcome to join me," I said shrugging.
"Sounds good. Give me a holler when you're ready," she said as she headed upstairs to her room.
I got a cold soda out of the fridge and chugged it. I was still sweating like a pig and decided to get a cold shower before movie night. I went to my room and peeled off my sweaty clothes and wrapped a towel around my waist. As I entered the hallway, I saw the door to the bathroom open and my sister came out. Her blonde hair was wet and glistening from the shower that she just took. Her body was wrapped in a towel tightly, making her breasts squish together to create a neat cleavage. She had medium sized B cup breasts, but they were very perky. Even when she didn't wear a bra around the house, I would notice that her nipples still stood straight out. I lingered for a second to watch the drops of water trickle down into her cleavage. I realized how awkward I was being when I noticed Erica draw her arms around herself self consciously as she hurried past me.
"Excuse me," I mumbled weakly as I entered the bathroom. There was a sweet scent of feminine shampoo in the air. I quickly took my towel off and entered the shower stall. As I rinsed the day's sweat off my body, I couldn't help but relive the fleeting moment with Erica. I reached down and touched my dick, which had gotten rock hard. I gave it some attention, and started to slide my closed fist back and forth over the hot rod, and pretty soon I squirted a healthy load of cum on the shower walls. I had the unfortunate combination of being a hormonal 18 year old who didn't have the confidence to ask a girl out, meaning that I was still a virgin. The only release I had was from self pleasure and I seemed to be hard 24/7.
I finished my shower, and changed into a loose pair of pajama pants and a clean T shirt and made my way to the living room. There was a menu for the local pizza joint and I put in an order. I knew that Erica was a vegetarian. So, I just ordered a large plain pizza. I flipped on the TV and scrolled on Netflix to see what is playing. Soon, the front door bell rang. The aroma of delicious pizza filled the living room and I didn't have to call Erica. I heard her door open and the sound of soft padded footsteps. Erica bounced into the living room. She was dressed in an oversized sweat shirt, shorts, and socks. Who wears a sweat shirt in this weather, I thought to myself.
We laid out the pizza on the living room table and plopped ourselves down on the couch next to each other. After we finished our pizza, we picked a movie to watch and were soon engrossed. Erica tried to make herself comfortable and I wrapped my arm around her so that she could nestle her head on my chest. She wriggled herself a little to get comfortable and I could feel one of her breasts press into my side softly. I was getting turned on and stayed perfectly still and controlled my breathing so that she wouldn't notice.
Half way through the movie, I noticed that Erica had placed her hand on my thigh and was absentmindedly stroking me. It was quite innocent and nowhere near my cock, but I started feeling the blood rush into my dick. As she stroked my thigh, every once in a while, my dick would throb. The loose PJ pants and my boxers did nothing to help contain my dick. The first time it throbbed, she paused. Her hand stayed still for almost a minute. To me it felt like an hour, though. I though I had been busted and my inappropriate hard on was clearly making it awkward for my sister. But, she finally just continued stroking my thigh as if nothing had happened.
After a few throbs, I noticed that she had moved her hand had moved further up so that it was practically next to my dick and she was stroking my thigh between my cock and my hip.
