"Come on in" I answered to the knock on my bedroom door.
In burst my sister Lilia and her friend Melissa, all smiles and giggles as they plopped down on my bed. Ordinarily I'd be a little peeved about them acting like they own my room but that day I was hoping for any excuse to pry myself away from my history homework. The fact that Melissa was smoking hot didn't hurt either.
"Whatcha doooooin?" Lilia asked as they proceeded to shuffle through the piles of papers and notes spread all over my bed.
"It's a project for school. Now quit touching stuff before you get me all messed up!"
Lilia stuck out her tongue and made a big show of moving her finger towards my book. I rolled my eyes.
"Very mature. Are you in here for some reason besides annoying the crap out of me?"
My sister flopped down onto her stomach, put her chin in her hands and flashed her "perfect, all American girl" smile at me.
"Actually yes. Have I told you lately that you're the best brother ever in the history of brothers?"
I sighed. "What do you want?"
"Jayna invited us to a party in the city and it's too far for a bus and we're too broke to take an Uber and we really really want to go so could you give us a ride pleeeeeeeeease?" She blurted out rapid fire.
I made a big show of considering it before saying "Sure. The Penguins game is on tonight so I'll go catch that at the closest bar while you guys party, then drive you home after."
Both girls screamed at a pitch that sounded like it could break glass.
"I told you he'd say yes!!" Melissa said and gave my sister a little tickle on her rib cage.
Lilia screeched and jumped on Melissa, tickling her back. The two started rolling around wrestling and giggling trying to get an advantage. Even though one of the girls was my sister, I couldn't help feeling a stirring in my cock while watching these two beauties roll around together in skimpy shorts and halter tops. My brain overrode my cock though and I hollered at them to cut it out before they screwed up my homework.
Panting a little the girls separated.
"I'm going to go get my phone and call Jayna to let her know we're coming!!" My sister said before letting out another ear splitting shriek and running out of the room.
Melissa didn't move to leave. She rolled over onto her stomach, then folded her arms up under her boobs and looked up at me. Melissa's boobs were definitely on the large side, and her arms folded underneath pushed them up and made them look even bigger. I couldn't help but stare.
"I really appreciate you giving us a ride tonight Jimmy." She said. Was I imagining it, or did she emphasize "giving us a ride"?
I've always had a bit of a thing for Melissa but I could never be sure whether or not the feeling was mutual. She was one of those girls who was always a little flirty, but always in a way that made you wonder if she was serious or joking. That flirtiness, combined with her gorgeous body, made my insides flutter a little every time she was near.
Melissa had a little bit of a punk rock style to her, always favoring torn jeans, black boots, and low cut t-shirts for obscure bands. I've always thought that short haired girls were sexy and Melissa always kept a very sexy "faux hawk" hairstyle.
"No problem" I replied.
"Hey, how about you come to the party with us instead of watching some dumb game?" She said with a sly smile.
"Umm, I dunno, you guys probably don't want me hanging around while you're trying to have a good time..."
"No I want you to come. I would really love for you to come tonight." This time she definitely emphasized "come". She even licked her lips.
The sexual tension in the room was so heavy I felt like I was on the bottom of a deep, warm pool.
"Sure...I mean...if you guys are OK with it..." My breath quickened as our faces moved almost imperceptibly closer.
Just then, my sister burst in. "This is going to be so much fun!!"
The bubble between Melissa and I burst. "Yeah, definitely" I said.
Was the smile Lilia gave us a knowing smile?
"Oh Lils, I invited your brother to come with us. I figure we owe him so the least we can do is to make sure he has a good time tonight." Damn, she was doing it again. "I hope you don't mind."
"Of course not." She said "We're going to have so much fun!!"
"Where's this party going to be anyway?" I asked.
"Some old warehouse downtown." Lilia answered.
"We're going to a rave?" I asked, a little surprised.
"Ugggh, no one calls them raves anymore old man." Lilia teased.
"Old man?!? I'm only three years older than you!"
"Yep. Anything older than 21 qualifies you as ancient." Lilia replied. "I've still got three years of wonderful youth."
"We'll see how young you feel riding in the trunk tonight. Now get out of here so I can get some work done before showing you light weights how to party."
Lilia grabbed Melissa's hand and started leading her out of the room.
"Come on Lissy, let's get out of here before he changes his mind."
I couldn't help but watch Melissa's ass as she walked out. It looked absolutely delicious in her tight short shorts. I tried to pretend that I didn't sneak a quick glimpse of my sister's equally delicious looking ass too. There was no way I was going to get any work done with my head filled with memories of her tits and ass, so I started putting my papers away and turned on SportsCenter.
A couple hours later, after a shower and a shave, I was dressed and ready to go.
"Are you guys ready yet?" I yelled down the hall.
