My name is Ashley and my best friend's name is Sarah; we're both the same age (16 at the time this story happened), and we've known each other since we were in elementary school, so we seldom spent much time apart as we grew up.

During the summer between our 10th and 11th grades, though, I went on a long vacation with my family and thus I didn't see Sarah for about two months until August of that year, just before school was about to start. So you could say I was surprised when I finally did drop by her house to go swimming before the summer

was over.

"Sarah, oh my God! Are you pregnant?"

"Well ... yeah," Sarah said, resting her hands on the generous swelling of her belly.

"Oh my God, how did that happen -?"

I then lowered my voice and added, "I thought you said you were a virgin!"

"Well, I was," Sarah said, "but then I had this accident..."

That wasn't TOO hard to imagine; Sarah was a pretty redhead and - unlike me - had a nice pair of boobs, so I could imagine her possibly getting herself knocked up at a party or such. Myself, on the other hand, probably not; I looked more like a boy with my flat chest and short blond hair, and most boys weren't all that interested in me.

"Come up to my room," Sarah added in her own whisper, "and I'll tell you what happened."

Needless to say, I was beside myself with curiosity and followed Sarah upstairs to her room, which was opposite her parent's room and down the hall from her 17-year old brother Jacob's room. Jacob happened to be in his room as we passed, working out with weights, and seemed a little embarrassed when he saw Sarah.

"Okay now," Sarah said, once we were in her room, "don't dare tell anyone, but Jacob is the father."

"Jacob!?!" I exclaimed. "No way!"

"SHHH!" Sarah said, putting a finger to her lips. "Yes way."

"Oh, man ... girl, that is sick! With your own brother?"

"Well, like I said, it was an accident..."

"Like what, he slipped and fell in your vagina?"

"Ashley, do you want to hear the story or what?"

"Yeah, yeah, I'm sorry. So how did it happen?"

Sarah then went on to tell me the sordid details while changing out of her T-shirt and jeans and into a turquoise bikini top and wrap (for later when we planned to go swimming in her pool). Way back in April when the weather started to warm up, Sarah couldn't resist going for a swim while her parents were at work and (she thought) her brother was at baseball practice.

So figuring no one could see, she took off her swimsuit and paddled around for a while until she heard a strange sound coming from her brother's room. She immediately realized her brother was there, so she put on her swimsuit, hurried upstairs and asked if he was watching her. He claimed he wasn't, but from the way his voice was strained Sarah could tell something was up; Jacob tried to keep her out of his room, but she barged right in and found him with his cock stuck through one of his barbell weights.

"No way! Seriously?"

"Seriously," Sarah said; "but wait, it gets better..."

Since Jacob felt masturbation wasn't manly - but he was definitely turned on by his sister - he decided to try fucking the hole in one of his 5-pound weights instead (figuring that would be more manly I guess), but then his erection got so big it got stuck.

"Seriously, it was HUGE," Sarah said. "As big as your forearm!"

I glanced at my forearm, which was slender, but still...

For a manly young man like Jacob, going to the hospital with a 5-pound weight on his dick was even more mortifying a prospect than being caught masturbating, but Sarah was sympathetic. After pausing just long enough to grab her camera and snap a picture (and freak out Jacob), she told Jacob she would help him get his dick loose if he promised to be her slave forever and ever. I thought that sounded a bit harsh taking advantage of her idiot brother like that, but Jacob agreed and Sarah then proceeded to sit Jacob on his bed, drop to her knees and give him a blowjob.

"No fucking way! Seriously?"

"Seriously. He actually started crying - because it was really sensitive, I guess - but then he went off like you wouldn't believe. He squirted a huge gob in my mouth - which was gross - then the rest squirted all over my boobs and got me all sticky. But the swelling did go down, and eventually we were able to get the weight loose with a whole bunch of dish soap."

"Damn, girl, you're a total slut!"

"Well, it's not like anybody knew ... and it was pretty sweet for a while. Since he was my slave, and I had the picture well-hidden where he'd never find it, I made him eat my pussy every day after school after that, and I'd give him blowjobs too if he was really good and made me cum. But then one day - after he finger-fucked me and I was all stupid with cumming - he just climbed on top of me and stuck his cock right inside me."

I stared at Sarah, disbelieving. Indeed, if she weren't swollen up like a beachball I'd have sworn she was shitting me.

"I told him to get off me," Sarah continued, "or I'd tell everyone about him jerking off, but he didn't care. He just started humping me, really fucking the shit out of me, and he said he was going to knock me up good for being such a bitch. I told him he BETTER not cum in me - and tried to push him off me - but he just held on tight and kept on fucking me until he came. I could actually feel it - his cum squirting inside me - and it ran all over my legs when he finally let me up. I ran to the bathroom and tried to wash it out, but he must have shot it really deep because he got me good the very first time."

"Damn, girl, that is fucking sick! Your own brother... ?"

Sarah shrugged.

"But still..."

"Still what?" Sarah asked.

"Well, I'm kinda jealous," I admitted. "I'm still a virgin and here you are all knocked up with your brother's kid."

"Twins, actually. That's why I'm so big."

"Jesus Christ! Do your mom and dad know?"

"Are you kidding? I said it was some guy I met at a party. From another school, forgot his name, didn't get a good look at his face."

"So did you ever do it again, after that first time?"

"Sometimes," Sarah replied, "if Jacob was REALLY good. After all, he couldn't knock me up any more than I already was."

"But damn ... you're going to have your brother's babies here in ... what... ?"

"Four months," Sarah said.

"Damn!"

Sarah looked at me sympathetically, then moved over next to the chair where I was sitting and sat on the armrest.

"So," Sarah said, "would you like some cock too?"

I swear I felt my heart flip over in my chest. In fact I did want some cock, and very badly, though I was too nervous and freaked out to articulate that clearly. I did manage to nod, though, and Sarah nodded back.

"I know you're there, Jacob," Sarah said to the door. "You can come in now."

Jacob, who was indeed there, obediently came around the corner.

"Jacob," Sarah said, "my little friend Ashley would like to see your cock. Would you show it to her please?"

"Jeez, Sis, do I have to... ?"

"It's that or have the whole school see your dick in that barbell weight."
