Mom and dad had gone to one of dad friends' funeral in Portsmouth and I and my sister would be home alone for the weekend.It had surprised me that mom and dad trusted me and had left us home without a sitter to look after us.I was sixteen, but I would never had thought that my parents trusted me that much.

That weekend was to be fun, as I would not have any adults home and I would watch my porno movies over and over again.My sweet sexy younger sister, Alice, was the only one home and, even though she was not allowed to go out without me, I didn't think she would disturb me while I watched my movies.She would probably stay in her bedroom either playing with her stuff or studying.She wasn't allowed to bring any friends over to play with her while my parents were away, for they didn't want anyone to know that we were alone in London.

Sis was supposed to be watching TV downstairs and I was lying face down on my bed watching my favourite porno movie.I was getting hard as iron and was about to pull my cock out and beat it when sis burst into my room.She went pale when she saw me there, watching something she had never seen in her entire life.A blonde was giving this lucky guy a blowjob when sis looked at the TV.I will never forget her perplexed look.

"What are you watching, Ron?" she asked innocently. "Is that a boy's thing?"

I didn't know what to say right then and it took me long to answer.

"Yes, but you shouldn't watch it" I finally replied.

"And what about you? Does mom know you watch this kind of movie?"

"Of course she doesn't, you idiot"

It was then, when I called her idiot, that I realized she wasn't wearing any pants, just a T-shirt and a skimpy pair of panties under it.

"Can I watch it, too?" she asked me.

"No, you can't"

"Then, I'll tell mom and dad you were watching it"

"You are such a...OK, then watch it"

I got up off my bed and sis looked at the obscene bulge between my legs.

"Oh my God! Have you seen that bulge you have in your crotch?" sis asked me.

"Yes, I have"

"Is it your thing that's making it?"

"Yeah, what else could be making it?"

Sis just shut her mouth, lay on my bed and started to watch a movie I never thought she would be interested in.After a while, I noticed that her t-shirt had ridden up and that I could have a full view of her cute firm panty-covered butt.My cock was about to burst.I had to do something or I was going to go mad.I decided to lie on the bed next to Alice, who continued to stare at the TV screen without even blinking.Sis was lying at the bed's edge, so I tried to lie next to the wall.As I crawled over my sister my bulge brushed against her butt.That sent shivers all through my horny body, but I got over it and lay next to sis.I couldn't stop thinking of how good it had felt to have my hard cock nestled between her buttcheeks, though.

I looked at Alice a moment later and noticed that she was mesmerized by the scene she was watching.In it, a guy was ramming his huge cock into a young brunette's hairless cunt and she was screaming in pleasure.

"Can a guy really put his thing into a girl like that?" sis asked.

"Yes, sure he can"

Sis was now kneeling on the bed.

"I wanna see yours, Ron" sis said.

It struck me, but I resolved to show it to her.After all, she would not tell my parents.However, she wasn't going to see it for free; I had my conditions and I wasn't willing to miss a chance of seeing a real pussy.

"I'll let you see it provided that you let me see your pussy" I said.

Sis hesitated for a while and then answered:

"OK, I will.But you do it first"

"OK"

I slowly pulled my pants down and my 7-inch cock sprang up.My sister was amazed.

"Oh my! It's big! And it has a lot of hair around it!" she exclaimed.

"Hadn't you seen a cock before, sis?" I asked.

"No, except for dad's when I was young and he once had a shower with me.But his was not that hard"

"It only gets this hard when a guy wants to have sex"

"I knew that"

I still don't know what made me say what I said, but the fact is that I said it.

"Do you want me to put it into you like the guy in the movie?"

Sis looked puzzled, but then she nodded.

"Do you really think it will fit inside, Ron?" she asked.

"Sure it will.Just take your panties off and I'll show you"

"Have you done it before?" she asked.

"Of course, lots of times" I lied, not wanting to let her know that I was a virgin.

Sis got up and took her T-shirt off.Her chest was flat and her figure was still that of a prepubescent girl.I looked at her crotch and noticed that there seemed to be no hair under her skimpy sky-blue panties.She put her hands at both sides of her panties and slowly pulled them down, letting me see her peach fuzz covered pink pussy.I was so turned-on I thought I'd explode.Her little panties fell to her cute little feet.Her toenails were painted in purple and that turned me on even more.She stepped out of her panties and stood totally naked in front of me and my raging hard-on.I told her to lie on the bed and spread her legs open.She readily obeyed and I walked towards her, my throbbing erection eager to sink into her.

I placed my cockhead in the crack of my sister's pink puffy wet pussy.I couldn't wait to thrust it in, but I decided to tease her for a while.I ran my iron-hard shaft all along her oozing gash and made her bite her lower lip.I knew she couldn't wait to feel my manhood inside her virgin pussy, so I resolved not to make her wait any longer.I placed the tip of my prick at the entrance to her hole and started to push forward.At first, only half of my cockhead sank into her tight teenage cunt, but I kept pushing till I found the obstacle I had been expecting.I pushed it hard with my cock until it popped.Sis screamed and blood started to trickle from inside her crack.I went to the bathroom to get a towel and wiped it off.Sis was now horny as hell and was eager to have my cock inside her again.I rammed it in again and sank half the length of my cock into her vagina.It was so fucking tight I thought I would hurt myself, but I couldn't stop, I needed to please that little cunt that craved for my hard iron-bar.

I kept forcing my cock up her cunt till I reached her cervix.Sis screamed again and I pulled my prick out, only to ram it back in two seconds later.I couldn't believe my 7-inch fuck-pole fitted inside her tight little hole, but I kept pumping my cock in and out it till I couldn't hold it any longer and came.I thrust my dick all the way up that teenage girlie hole and I thought I had popped her cervix open, too.Spurt after spurt, my balls were drained of baby-making goo.When I had finished squirting my hot seed into my little sister's tight cunt, I slid my cock out and looked at her reddened hairless vulva.Sis had her legs still wide open.I rested my hands on her flat chest and kissed her lips softly.She closed her eyes as I did that and felt my semi-hard battering-ram rub her hungry little crack.I then ran my tongue down her chest and belly till I reached her cunt.I knew very well she had not come yet, so I started to lick her juicy crack.I loved the taste of her girl-juice and couldn't get enough of it.I ran my tongue up and down her girlish gash and then focused on that little pea I knew made girls go crazy.As I had expected, sis moaned even louder than she had before and, after a while, was writhing in pleasure as a wave of ecstasy went through her no-longer-virgin little body.I continued to suck her cunt even after she'd had her first orgasm and gave her two more.I had a mixture of her juices and my saliva all over my face and I loved it, I loved to please my little sister.

When I had finished licking her cunt, I French-kissed her for a while and then we both lay on the bed, stroking each other.It was still Friday night and sis still had two more holes untouched.It would be a very enjoyable weekend.
