It was almost 2 a.m. My parents were away for the weekend and my sister was out with some of her friends. Since our parents were gone we were both obviously having a good time being on our own but it was getting late and I was actually getting a little worried about her.

Finally a car pulled up in the driveway. Well, there she was. I could just finish watching this movie and go to bed.

My sister Andrea stumbled in. “Hi Jimmy!” She’d obviously been drinking.

Damn, I had to admit, my sister was hot! She was seventeen, a year older than me. She had a near perfect body, long legs, round, sexy ass, trim waist and big, firm breasts. She also had long, lustrous black hair and big, beautiful brown eyes.

“Where the heck have you been?”

She walked unsteadily across the room and started to plop down on the couch. Instead she landed in my lap.

“Oops!” She giggled. “Oh Jimmy, were you worried about me?”

“No, I just-”

“Aw, you’re so sweet.” She leaned forward and kissed me. Her soft lips pressed hard against mine and then… Holy shit! That was her tongue in my mouth! My sister was making out with me and it felt really good!

“You know, you’re really cute, Jimmy!” She giggled and kissed me again. She squirmed around. “Whoa! What am I sitting on here??”

I gulped. She knew damn well what that was poking her in her tight little butt.

She slid down onto her knees on the floor and her hand slid over the bulge in my pants. It took her a couple of tries to pull the zipper down but I didn’t try to stop her. Didn’t say a word. I hardly breathed.  I couldn’t believe this was happening!

Finally she unzipped my pants and my dick popped out. I gasped as my sister’s slim hand encircled my cock and started slowly sliding it up and down.

“Ooh, this is big, Jimmy!” Actually it was pretty average but I couldn’t have said anything if I wanted to.

She leaned forward and ran her tongue over the head of my cock. I actually whimpered. She took it into her warm, wet mouth and slid her lips up and down my cock for several minutes, rolling her tongue all over it. I was about to cum right in my sister’s mouth!

Then she stopped.

She pulled herself to her feet. “Oh well. G’night, Jimmy.” She leaned down and kissed me on the cheek then went into the hall and up the stairs.

I just sat there for several minutes with my dick sticking straight up, trying to understand what had just happened.

Then I got up, tucked my dick into my pants as well as I could and rushed upstairs. The light was on in the bathroom and the water was running. I snuck past and into my room. I got into bed and started to calm down. Okay, she was drunk. In the morning she probably wouldn’t even remember it.

I heard Andrea moving around in her room. Suddenly the door opened and she stood there in the doorway. It was dark but I could see that she was naked.

“Andrea! What the hell are you doing?”

“There’s crap all over my bed. Lemmee sleep here.”

“No! Just go-”

She sat down on the bed and lifted the covers. Then she slid into the bed butt first so that I was unintentionally spooning her. Her fantastic bare ass bumped against the front of my shorts and I had a new erection in seconds.

“Mmm, this is nice.” She snuggled back against me and, without really meaning to, I put my arm around her waist.

We lay there like that for a while. She kept shifting, always moving closer against me. Her breast bumped against my hand and I guess I have to admit I moved to get the maximum contact with them without being obvious.

Then she just blurted out “Hey, you want to fuck me, Jimmy?”

“What??  No!!”

“Oh come on! I know you want to. I can feel your boner back there.”

“Well of course! You’re naked! But you‘re my sister!”

“So? I’m on the pill.”

“Yeah, but…I mean…come on!”

She turned toward me and put her finger over my lips. “Just relax. It’s okay.” She said softly and gently. She moved her finger and kissed me again. “You’re still a virgin, right, Jimmy?”

“Uh, y-yeah.”

“I’m not. But…it wasn’t that great. I think this could be lots better.”

She continued to kiss me as she pulled down my shorts. I completely gave in to temptation and squeezed my sisters tits. They felt so good! So warm and soft but firm. I leaned down to lick and kiss them and she moaned happily.

She rolled onto her back and pulled me on top of her. “Stick it in me, Jimmy! God, I’m so horny!”

I might be going to hell but this felt way too good to stop. I found my sister’s wet, swollen pussy with my fingers and clumsily slid my dick inside.

She was hot inside and so tight. Her pussy felt amazing squeezing my cock. I wanted to start pounding her like crazy but I made myself go slow at first.

“Ohhhhh Jimmy! That feels so gooood!” She moaned. She wrapped her arms and legs around me, pulling me close to her and gazed up at me with her big, dark eyes.

I couldn’t take much more of this. I started moving faster. She moaned and writhed under me.

“Oh, I’m cumming! Oh god! I love you, Jimmy! Ohhh!!!”

“Love you!” I managed to gasp as I shot my load inside my sister.

“Oh god, that was sooo good, Jimmy!”

“Yeah. Yeah it was awesome!” I gasped.

She cuddled up against me and in seconds we were both asleep.

I woke up and looked over at my naked sister laying beside me. The blanket was down low and I could see her breasts clearly in the morning light. I just stared at them for a few minutes and then I tried to get up. Unfortunately we were both pretty tangled in the covers and I shook her awake.

“Jimmy?” She murmured thickly.

“Um yeah.” I gave up and laid down next to her again. “Uh, Are you okay?”

“Sure.” She opened her eyes and smiled at me. Her breath was awful but she looked really cute in a rumpled, bedheaded way. “So…I guess that really happened last night, huh?”

“Uh, yeah. I’m sorry.”

“It’s okay. We didn’t do anything that wrong. I always make sure to take my pills.”

“O-okay but-”

“Actually, I’ve had a few dreams about that. You and me. But that wasn’t a dream, right?”

“No. It really happened.”

“Good. I’m glad.” She groaned. “Would you get me some aspirin? Please, Jimmy?”

“Yeah, sure.”

I got up and pulled on my shorts and then pulled the covers up to her neck. I brought her aspirin and a glass of water. I also close the shades to block out the sun.

“Mmm, thanks.” She sighed. “That’s better. My head’s still pounding, though.”

I sat down next to her and started rubbing her temples in the way that helps when I get a headache.

“Ohhh, that’s nice.” She purred.

I massaged her head for a while and then she got up and went to the bathroom.

I got up and just kind of paced around the room for a few minutes, unsure what to do.

She came back, still naked, and came up close to me again. She kissed me. Now her breath smelled of mouth wash. “Want to go shower?”

“Uh, yeah, sure.”

She took my hand and led me into the bathroom. I started the water going and then dropped my shorts and we stepped in together. She was still pretty groggy and leaned against me as the water ran down on us. I took the soap and started washing her.

Here in the bright bathroom light I could really see my sister’s amazing body for the first time. I soaped her back and butt. She giggled and nipped my earlobe as I slid the soap between her legs. Then she leaned against the wall and I washed her big, soft breasts and firm, flat stomach. I rinsed them and couldn’t resist sucking her nipples a little. I leaned down to wash her legs then I stood up and even washed her hair.

Then we started kissing again.

“Hey, I started giving you a blowjob last night, didn’t I?”

“Yeah.”

“But I never finished.”

“No, you didn’t.”

“Well, I don’t want to be a tease.” She sank down to her knees.

She started licking up and down my dick and then she leaned down to play with my balls. Then she squeezed her fantastic breasts around my dick and started jerking me off with them, licking my head when it popped out the top. Then I started to cum. She took it deep into her mouth, all the way down her throat and I pumped my hips forward, emptying my cum straight down my beautiful sister’s throat.

We got out of the shower and dried each other.

She turned and threw her arms around me and lay her head against my chest. “Oh Jimmy! I know you’re my flesh and blood brother but you’d make such a great boyfriend! You’re so sweet and cute. And so good in bed.” She sighed. “Of course we’d have to be really careful. Especially around mom and dad.” She paused and looked up at me with her big, soft eyes. “I mean…if you want me.”

I kissed her. “I love you, Andrea. And I want you to be my girlfriend. Even if you are my sister.”

“Oh, I love you, Jimmy!!” She squealed and squeezed me tight.
