Ben leaned back against the car, exhausted, "you swalloed all of it?"

"Every last delicous drop"

He grinned, "So I was alright?"

I stood up, pressing my naked body against his...feeling his cock going soft, "you were great."

He looked back at me, "can we, like stay here for a little while?" I grinned, "sure".........

After a few minutes, his small cock was soft again and I knew our parents and family would be wondering where we had dissapeared to for so long.Â

I softly whispered, "we should be getting back you know, it's still your birthday."

He whimpered a little, "do we have to...this is way more fun."Â I laughed, "yeah, we do...come on, let's get dressed"

We quickly got dressed, although Ben did watch with infatuation as i bent over to pick up my thong. I grinned a little, but within a few minutes we were driving back down the road towards our house. Every now and then when I would look over at Ben's pants I would see the tent, just as hard as when I had been sucking him earlier, and to tell the truth, the taste of his cum was still heavy in my mouth and was keeping me wet as well. We pulled into our driveway about ten minutes later to see most of our family members getting in their cars to leave. We wished them a safe drive home, and thanked them for Ben's presents. Our mother walked over to us a few moments later, giving Ben a big hug she wished him happy birthday again. I wanted to laugh, because if she was just a little more aware she would notice that her son's hard cock nearly poked her as she hugged him. She walked over to me next,

"Sarah, how are you sweetheart?"

I smiled, "well, I don't know about you, but Ben turning 14 is kind of hard for me to swallow...he's just so big,"Â looking at Ben I thought he was either going to die of anxiety or burst out laughing.

Mom, totally oblivious to the inside joke, just smiled. "Well he's going to be a fine young man I think." I smiled, "I think your right about that mom. So what are you and dad doing tonight?"

"We were thinking about having dinner here and maybe the four of us could go to a movie or something. How does that sound Ben?"

Now at this time I had no idea or intention of continuing our relationship farther than it had gone. But I totally underestimated the lust of a teen boy. Ben seemed thoughtful for a moment, "well mom, I was kind of wanting to just spend some time with Sarah today. But if you and dad want to go see a movie that's fine with me."

Our parents were always pushovers when it came to either of their childrens' happiness so I wasn't at all surprised when she smiled and said that she'd be happy to give us some time to catch up. I waited until mom had dissapeared back inside before turning to Ben,

"Ben, what the hell is that?"

He looked a little hurt, "I thought we could have some time to....well, do some stuff."Â I sighed, thinking, mainly about the fact that my panties were still damp from the feelings and thoughts I was having on the way home a few minutes earlier.Â

"Ok, but no sex. Just messing around and talking, deal?"

He practically beamed, "Deal!"

We walked upstairs where I brushed my teeth, and washed up a little. As I walked out of the bathroom he was over by my dresser, looking at some of my thongs and bra. I locked the door for safe measure and laid down on my bed, propping my head up on one arm. He walked over holding up a pair of sheer see-thru bikini bottom panties.

"So do you wear these often?" I laughed, "every now and then," he sat down next to me. We started to talk about everything. How long had he wanted me, what made me decide to do what I did, how many men and women I'd had sex with, but most of all we talked about incest. Who in our family I'd be willing to have sex with and who he wanted to have sex with. Mostly, and to my surprise, he wanted our mother who at 47 looked young enough to be 37. I admitted that I'd be willing to sleep with our father who at 52 wasn't in the best of shape but according to the moans that used to come from our parents bedroom, he was still a decent lover. As hour after hour passed both of us were increasingly becoming hard and wet. Realizing that sooner or later I was going to have to get myself off.Â

I looked at Ben, "will you watch me masturbate?"Â He nodded, "can I do it too?"

I nodded and he unzipped his pants, pulling the down to his knees along with his boxers, exposing his hard 4 1/2 inch cock. He looked at me and i lifted my skirt around my waist, lowering my panties to my ankles and taking them off. I began to rub my pussy, especially my clit as i watched him take his hard cock in his hand and begin to stroke. We watched eachother for a minute, then two, our pace increasing as we both started to moan, but trying to keep it low since our parents were only down stairs.Â

Ben watched as my juices began to soak down my thighs to the sheets of my bed, "how does it taste?"Â He asked.Â

"What?" I asked

I brought my fingers up to my mouth, thinking about it. "I dunno, it just tastes good I guess."

"Can I taste it?"

I thought for a moment, it felt kind of wrong, almost as if I was taking advantage of him, but I wanted it so badly, "Sure...but I cum alot, so I don't want to squirt all over your face."

He grinned and climbed over as i spread my legs. He hesitantly got comfortable and leaned closer. He gently pressed his mouth to it and I felt his tongue run along my slit, tasting the juices. I guess he liked it because he quickly began to lick it faster and soon he was pressing his tongue into my pussy. I laid there for at least 5 minutes as his tongue worked over my pussy, bringing me closer and closer to an orgasm.Â

As I felt myself getting close to the edge I warned him, "Ohhh my God, Ben...Ben, watch out, I...I'm going to cum!" He quickly sat up, as did I. He sat there between my legs watching as I began to furiously rub my clit, our eyes staring into eachothers. Then his attention returned to my pussy as I came. I had to cover my mouth to stiffle the moans as my pussy erupted, gushing juices out onto the bed, to the amazement of my brother. As the cum subsided I slowly relaxed, collapsing back on the bed, laying in the soaked sheets, breathing heavily.Â

Ben, climbed up beside me, "Oh my God, Sarah..."

I grinned, "Did you like that?"Â He nodded, "Yeah!"

I sighed, "now, where do u want to cum?"Â He thought for a moment, then hesitantly said, "Well, I...I want to cum on you, but I don't want you to wash it off before we eat dinner with mom and dad."Â

"So you want a little thrill knowing that I'm wearing your cum to dinner?"Â He nodded his head, "Yeah, will you let me?"

I smiled, "Sure, how about on my ass?" He grinned, "Perfect!" I got up, still naked from the waist down and got on my hands and knees on the bed. I felt the bed shift as Ben positioned himself behind me and heard him begin to stroke himself. I felt a small hand softly begin to feel over my butt, then I felt the rock hard cock begin to rub over my butt. I felt his cock removed, and then with a gasp of surprise I felt the same hard member shoved into my pussy from behind. I turned in surprise, but he had me by the hips, holding his cock steadily inside me.Â

"BEN! I said no sex!"

"Sarah, shhh, please, I promise I just want to feel it..."Â In an awkward position I looked into his pleading eyes, then finally submitted, although a little bitterly, "ok, but please, whatever you do, don't cum in me."

He nodded, "I promise." He slowly began to slide his hard cock in and out of me, his sister, enjoying the first pussy he had ever seen or felt. I knelt there on my hands and knees as he began to thrust faster and harder as his awkwardness gave way a little.

"Ohhh fuck this feels good Sarah..." His soft moans began to get louder and louder, I was almost certain this at any moment my mother was going to knock on the door, wanting to know what the noise was in here. But no more than four or five minutes later I felt him pull out of me and I heard his hand stroking his wet cock.Â

"Oh fuck Sarah I'm gonna cum on you!"Â

I looked back over my shoulder, spreading my ass cheeks with one hand and supporting myself with the other, "Mmm, yeah, Ben cum on my ass and pussy. Do it for your sister"

He gasped out a few more breaths before I felt his hot gooey cum begin to shoot all over my ass cheeks, down the crack, and even onto my pussy. Again and again the shots kept coming, coating me in his sperm. Finally he fell back onto the sheets, his glistening cock still hard. Smiling, unable to remain angry that he fucked me without consent, I turned around and lowered my head to his cock, sucking off the last of his cum and my juices as well. I slowly climbed off the bed, making sure to keep my skirt above my ass so as to not smear the cum. I grabbed the camera out of my bag and handed it to him. Grinning I told him to take a picture. He took the camera and snapped a shot of my cum covered ass. Knowing what would happen if our parents found these, but that making it just more of a thrill i posed for a few more pics. Some of me sucking his cock, some of me stroking him, and one of him fingering me.Â

I had just pulled my panties over my cum covered ass when Mom knocked on the door to tell us it was dinner time. I grinned at Ben and we walked downstairs together.

As the four of us ate dinner, both Ben and I appraised our parents a little more, wondering what they looked like when they fucked and what sort of things they did. I grinned at him, and he grinned back. Knowing we would have plenty to talk about and do when they left that evening.Â

                                 THE END

Thanks for all of the feedback. I'm really glad everyone is enjoying this and I promise there is much more to this story. Hopefully the problem with the ? will be taken care of this time. Thanks again, Sarah.
