We are caught in the act!

I gave her a big kiss and asked, "Now that you know our secret, do you think any less of us?"

"Of course not! But it is quite a surprise, I never would have guessed!" she replied, "Actually, it's kind of exciting!"

John sat down, on the other side of Kim, now totally naked, his massive rod jutting up from between his hairy legs. Kim asked him again, "So, is Ken going to find out about me and your blowjob buddy?"

"Not when you put it that way! Now that you have some dirt on me, I guess, I'll have to keep my mouth shut."

"Good!"

Then she bent down and took his cock into her mouth, or at least most of it and he moaned loudly.

"You're going to be impressed at how good your sister can suck a dick, she's the very best!" I told John, "Incredibly talented!"

She stopped sucking his dick just long enough to say, "Why thank you!" She went back to blowing him, making him groan with pleasure. Then she said, "Why don't you help me get him off, since I know about your little secret?"

"Well, as long as you're twisting my arm!" I got down on my knees between his legs and leaned forward, licking his throbbing shaft, as she sucked the head. He groaned, as she pulled his big swollen head out of her mouth, both of us licking it, her on one side, me on the other, our tongues twirling together, wrapping around his purple head. He sucked air through his clenched teeth, throwing his head back, moaning loudly. I knew that he wouldn't last long, just imagining how intense it must feel. He bucked his hips up and down, his body writhing with pleasure. We kept up the pressure, each taking turns slipping the head into our mouths, her playing with his balls, as I stroked his shaft.
I said, "Since he's your brother, you should do the honor of sucking the cum out of his cock, don't you think?"

"Mmm, hmmm!" She moaned.

He started to grunt and groan, saying breathlessly, "I'm cumming, I'm cumming!"

As she sucked on the head, I jacked him off, into her mouth. It felt incredible, as his huge prick got even bigger in my hand, I could feel the powerful spasms, the big cock surging, as he squirted gob after gob of hot cum into his big sister's mouth. She slurped it all down, except for one little stream, which ran down his shaft and onto my fingers. John collapsed after what has to be one of the biggest orgasms of his life. Once she was done milking his massive tool, I held my hand up to her mouth, so she could lick his cream off of my fingers.

"Jesus, that was incredible!" John panted.

"I told you she was the best!"

Kim said with a smile, "Maybe, but I had some help this time!"

"Why don't we go to the bedroom?" I suggested, they both agreed.

Once we were in my bedroom, I laid down on my back and said, "Hey John, it seems like you kind of owe me, after all, you got to feel me lick your cock, while you fucked a hot lady when we were in Las Vegas. I think it's my turn, that is, if you don't mind licking your big sisters hot clit! What do you think?"

Kim blushed and looked at John, with an expectant look on her sweet face.

"Are you kidding me? I'd love to!" he replied. "That is, as long as Kim is cool with it."

Kim smiled and said nothing. She just climbed up onto me, impaling herself on my prong, with her back to me. She started to move her hips up and down, her wet pussy, clenching my hard cock, pulling at it on the upstroke. Man, did that feel good! John got down between our legs, I could feel his hot breath on my balls, as he started to lick her little nub. Kim moaned with pleasure, as his tongue made contact with her clit. Then I finally got to feel the sensation of someone's slippery tongue, licking my shaft, at the same time it was stuck up a pussy, a feeling I had never felt before. Starting with my balls, he licked up my slick, wet cock, to her clit, sending a spasm through her body. I felt his hand, massaging my nutsack, it was a little strange to feel a hand that was not as soft as Kim's on my balls. He licked up and down my shaft, as she rode my cock, slowly slipping her wet pussy up and down, stimulating my rod. The feeling was exquisite! She would move up until just the head was still inside of her, then she would wait, letting him lick my shaft a few times and then drop her body down, my cock sliding deep inside of her. One time, she went up too far and my wet dick popped out, John grabbed it and pulled it toward him, sucking it into his mouth, causing me to groan. Then he took it from his mouth, after bobbing up and down a few times and aimed it back into her waiting pussy, as she dropped back down.

This continued for some time, then Kim started to groan and her breath became ragged. Her movements were starting to become erratic, I could tell she was close to orgasm. John must have sensed it as well, because he stopped licking my shaft and he concentrated on her hard little clit. His hand remained on my balls, holding them and rubbing them, as he flicked at his sister's most sensitive parts with his tongue, my cock buried to the hilt in her warm wet hole.

"I'm cumming, I'm cumming, oh God I'm cumming!" She screamed, the muscles in her tight cunt, convulsing, gripping my hardness. She laid back against my chest, her whole body tensing up, as I reached around to grab her sweaty tits, kneading them as she flooded my crotch and John's face with her love juice. After a huge orgasm, she collapsed, her body relaxing, as she laid on top of me. John slurped up as much of her fluid as he could from her pussy lips, my nuts and his hands. She laid there for a moment, as I felt the last twitches of her pussy, still wrapped around my throbbing manhood.

"Oh my God, that was incredible!" she exclaimed. Then she rose up and lifted herself off of my body, dislodging my prick from her soaking wet snatch, my cock flopped down on my belly with a wet slap.

"I want to see you finish him off, little brother," Kim said.

John just smiled, as he resumed his position between my legs. He grabbed my hard shaft and started stroking it slowly, causing me to moan from the pleasure. He licked the swollen, purple head of my dick, I gasped, throwing my head back, as I felt electric like pulses run through my body. He took my head into his mouth and started bobbing his head up and down, as he stroked the shaft at the same time. His teeth gently scraped the head of my cock, which brought me to the brink of ecstasy. I was having a tough time holding back, trying not to shoot, wanting these feelings to last forever.

Kim watched, fingering her wet pussy, as her brother sucked on my rock hard tool. Then she couldn't resist getting down on her knees and joining him as I got closer and closer to releasing my seed. They both took turns, sucking the head of my lucky penis, both of them had their hands on my nuts and shaft, each licking at a side. That was all I could handle, just the sight of the two of them, both tongues slithering around on the head and shaft of my hard prick, causing me to let loose with a huge load of sperm. It shot up into their faces, as I spurted glob after glob of hot semen, landing all over their faces, hands and my belly. My body relaxed, I watched them lick my cum off of each others face and hands, as they giggled, settling into a hot kiss.

I laid back, feeling quite satisfied, as I watched them kiss each other like they had been lovers for years. Kim laid down on her back next to me and said in a sexy voice, "Come on Johnny, I want you to stick that big fat cock of yours up my pussy!"

He had a stunned look on his face, "I...I don't know, do you really want to go that far? After all, y...you are my sister."

"Get over here! It doesn't matter, I'm on the pill. Besides, we've gone this far and I want you to shoot your cum in my pussy, now get over here, NOW!" she said, in that demanding tone I had heard so many times before.

He looked at me, I smiled and then he moved toward her, "All right Sis, if you think it'll be OK!"

"Just get over here!"

His cock was purple and dripping pre-cum, from all the hot activity. It had been neglected for quite a while, all the attention had been paid to my now wilted dick and her wet twat. He moved over on top of her and I reached over and guided his rock hard throbbing pole to her dripping slit. He stopped with the massive head resting against her opening, slowly applying pressure, until it suddenly slipped inside her tight little sex pot. She let out a loud groan, her body writhed with pleasure, John gasped, as he felt it slide in.

"Oh my God, it's so big!" she cried out, panting as he slowly sunk it in to the hilt.

I felt a slight pang of jealousy, as I watched him lie on top of her, his massive boner inside her body. I always knew that at times, she still had sex with her husband, but as long as we didn't talk about it, I wasn't bothered by the thought. But now, here was another guy between her legs. Even though it was her brother, I just wasn't used to seeing her with someone else. I guess it didn't help that his cock was so big, at 9 inches, he was bigger than I was, my 7 inches looking small in comparison. Kim seemed to sense my feelings, she turned to me and smiled lovingly, as she ran her fingers through my hair, then she kissed me deeply.

John started to work his dick in and out of her little wet quim, it making slurping sex noises as he pumped her. She started to moan, her gorgeous tits bouncing in circles, as he fucked her, picking up the tempo, his large balls, slapping her ass. I tried to put my feelings aside, after all, she didn't really belong to me, so I had no right to be possessive. Besides, it was pretty hot watching his massive tool, plunge in and out of her! I reached over and wrapped my index finger and thumb, around the base of his shaft, my fingers feeling his nuts slap back and forth. That helped quite a bit, at least by doing this, I was a part of it.

"God that feels great!" he said between breaths. I had to agree, as he slid in and out of her, I would feel her wet lips slapping against the back of my hand, as it was sandwiched between her pussy and his balls. I did this until he was slamming into her so hard I just got my hand out of the way, so they could enjoy the thrusting of his full length, deep inside her hot body.

Soon, he was groaning, "I'm going to cum, I'm going to cum!!!"

"Squirt your hot cum inside of me, little brother!" she screamed.

His strokes became erratic, as he sprayed his jizz deep inside her clutching pussy! "Oh my God, that feels good!" Kim screamed, as she writhed on the bed.

His thrusts started to slow down and then gradually coming to a stop. Then he laid down on top of her, trying to catch his breath.

He moaned, "That was absolutely incredible!"

After he laid there for some time, he got up and said, "As much as I hate to admit it, that was the best sex I've ever had!"

"I know the feeling! Your sister is incredible!" I agreed.

Then he started to get dressed, "I also hate to say it, but I've got to go home. I've got to get up in the morning, to go to work."

"So do I, unfortunately," said Kim.

We reluctantly got dressed and they both left, after a hot kiss from Kim, that is. I could only hope we will all get together again, for another hot night of great sex! I'll keep you posted!
