About a month ago, my half sister and her best friend were up in my apartment. I live above the garage at my folks house. Easy access, no crazy expenses, they don't ask questions even if they see a car in the street, or they suspect something is going on. I'm not loud, don't get stupid, and I've never had the neighbors call the cops because of my crazy parties. I like to drink, smoke and fuck. Pretty simple life. I have a good job, work regular, hang with my buddies, and like to chill. When my half sister comes up, she chills, usually smokes a bit, maybe drinks a couple, and sometimes crashes out on the couch. She's had some of her younger friends up there, and yeah, I've fucked a couple of them. I'm 25, but the high school chicks just do it. They like to get stupid, and it's funny hearing them say "I drank so much I don't remember". Yeah. They remember. They just don't want to admit it.

Well, when my sister Kylie and her friend Betsy came upstairs, I was chilling on a Saturday night. I'd gone out a couple times during the week, had a good time, and that night I was gonna drink a few, check out some porn, probably jerk it a bit, and crash. I guess they were bored at my folks house, which is funny, because my parents had gone out of town that night, and they would have had the house alone to do whatever they want. Well that night they came up got pretty hot, and it was awesome. I saw a side of my sister I'd never seen before. I'd never seen her make out with chicks before, and it was pretty damn sexy. Betsy isn't the "hottest" chick in the world, but she's got a nice set of tits, and a little round ass. And she's got a mouth on her, swears all the time, and is pretty blunt. Well, after a few beers, I lit up a joint, and we were smoking down, and whatever happened, Betsy just plants one on my sis. It was hot. Just sitting on the couch, I kinda went "wow" and they started making out. Yeah, creepy sounding, even though it's my half sis, but watching her get made out with by another chick got me hard. Got me thinking about some hot sex, maybe a dirty kinky thing, or whatever. Funny thing is? That night, well, I ended up making out with my half sister a lot. Some serious tongue. Got a feel up of her little round firm tits. Got a squeeze of her ass. And I ended up that night, when Kylie fell asleep, fucking Betsy for almost an hour. I'm telling you, for not "bad" looking, she's just OK, she knew how to fuck. It was pretty intense, and she ended up blowing me and letting me nut in her mouth to finish me. Pretty hot. I've never had a high school chick swallow before, so that was a new one.

Last weekend, I was up in my apartment, and I heard a knock. It was my half sister. She came in. Was chilling, asked if I was hanging out alone, and I said yeah. She was sitting on the couch and wanted to do some drinking. She's only in high school, but my folks don't know. I'm sure they suspect, but they've never said anything. So we're hanging out, just chilling, I had some music on, lit up a joint, and offered her some. She'd never really smoked, but said yeah. Took a couple of hits. We're relaxing, and she asks me about Betsy. I told her. I always share the dirty shit with her. She asked if it was good. I just shrugged and said well she's OK looking. No offense, she's your friend. But she's not the hottest. And no, no fucking. She blew me off, and let me nut in her mouth. My sis just kinda looked at me and laughed and said well I've never done that. How was it? I just said it was kinda hot. She took it all, so I liked it. I'm not gonna complain when I cum. Kylie just laughed. I asked why she was asking. She just shrugged. And I kind of laughed and said well there's always a first time for everything. Her face got all red. I just laughed and said I was joking. She took another hit on my pipe, and said what if I wanted to? I just stopped. I said what? And she said what if I let you do it? Nut in my mouth? I just kinda laughed and said well your my sister, kinda weird. And she looks at me and says to me, well, like you said, first time for everything.

Now I've never looked at her that way. Seriously, not ever. But we're sitting there, and I check her out kind of casually. She's got a tight pair of jeans on, a cool hanging down shirt, I'm seeing some cleavage, and I know she doesn't have a huge rack. But nice. She's kind of on the skinny side, and I guess my guy hormones got going. I just kind of laughed and said well I'd never turn down some fun. But well yeah, it's kinda weird. She just looked at me and said before I change my mind, I wanna do it. I didn't hesitate. I said well as long as it doesn't get out, and you don't talk to anyone. She laughed and said sure. I'm gonna share with my friends I did shit with my brother? That'd gross them out really quick ya know? I said yea with a laugh.

She was standing in front of me, and said well, what do you want me to do? I just shrugged and said I dunno come here. She was near me, I pulled her down, opened my mouth, and we started kissing. It was fucking hot. She knew how to kiss for a chick her age. Had her tongue in my mouth, and I felt my dick pop. It was bulging, and I stopped, pulled back and said with a smile it didn't take much. I'm already ready if you know, you're into it? She said yeah.

I unzipped my pants, pulled them down, and I said why don't you do the same? She said what? I said I dunno, let me see some of you too. She said well sure, I mean, I guess. And she unzipped her pants, squeezed out of them, and unhooked her shirt. She's standing there in a cute little pair of white underwear, and a bra. Skinny stomach, not real big boobs, but fuck my dick was hard. She kind of kneeled down and said like this? I said yeah. I pulled my boxers off, and she just said holy crap. I said what? And she said yeah, uh yeah, OK. I kinda laughed. She touched it, and I jumped. She looked at me and said what's the matter? I said nothing. I was hard as hell.

She started stroking it, and I was leaning back, and bam. I felt her mouth on it. I about poked her in the throat with it. She yanked her head back and laughed. I said sorry. She started doing it again. I was watching her. She kept going and going, and goddamn, it felt so good. I really wanted to hold off. She was going at it for like 15-20 minutes, I kept going, throbbing, and I'd slow down.

She finally had me right there. I told her Kylie, you better watch out. It's gonna go. She sucked. It just squirted. I felt it gush. I saw her. Her throat was moving. Then again. And even more. And eventually I was cumming so hard and fast, she couldn't do it all. It ended up overflowing, and got on her face and chin.

She finished it off. Literally, took it all, emptied me out, and was kneeling down when I just laid back. I was soft, limp and just breathing hard. I saw her face, she smiled and said wow. And laughed. I just kind of laughed and said well, now you've done a first for everything. And she kind of laughed.

Laying there naked for a couple of minutes, I saw her get up and walk into the bathroom. I was watching her little ass twitch as she moved. She came back like 5 minutes later, and said well how did I do? I just laughed and said jesus, for your age, and telling me you'd never done that before? Good god, fucking amazing. It was intense. I loved it.

She was sitting next to me on the couch. And without a word, moved over sideways, and straddled me. I looked at her and said what the hell? She pushed. Said I know you're not ready. But I really wanna do this. I've wanted to for like 2 years. Will you fuck me? I said what? She said I'm for real. I wanna do it. I won't say anything. But I really wanna fuck you. I mean really bad. It was hot as hell. Scary. I freaked out. I told her no way. I said I couldn't do it. She said why. We talked. I don't know why I'd decided. But about 10 minutes into it, she's on my naked limp dick, I decided to see if she'd really do it. I was staring at her little tits, and her flat skinny stomach, and I kissed her again. She reached back and unhooked her bra. I started fingering her nipples, playing with her little tits, and I felt my dick getting hard. She felt it. Looked at me, and moved kind of sideways. I see her hitching her underwear off, and I'm looking at her pussy. Shaved. I just stared. And she said what? You've never seen one like this? I laughed and said yeah. But not on a 16 year old. She laughed and said well first time for everything huh?

I was getting really hard. I moved her off me, put her on the couch, and she said wait? What are you doing? I just told her to lie still. I ate that teen pussy so hard that I made her cum. She was pushing against my face, and she just let loose. Started gasping and moaning really hard. I didn't even ask. I know I should have, but I just stuck my dick inside her. It went all the way in, really slippery and all wet. She soaked me. And I heard her say "wait. Matt. You gotta wait. I'm not on anything right now. Please. Be careful". I said OK.

I slid inside her, and pulled back, pulled it out, looked, and it was soaking wet from my sister's pussy juice. I slid back inside her. And god, it took me like four pumps, and I had to go. I couldn't stop. I yanked it out, and I squirted all over her stomach. It was intense. Seriously hot and steamy. I was squirting my cum all over her skinny little stomach. She heard me gasp, and I kind of fell on her on the couch.

We laid there, and a couple minutes later, got cleaned up. After, we were sitting there, and talking. And she said OK. That was a bit weird. Different. But god. You were like really good. I told her I wanted to really let loose inside her. And she told me that she wanted to again, and we'd do it another time.
