“Oh wait a minute. He’s finally cumming! Oh God, I’ve never felt anything like this before! It feels like he’s completely filling up my vag with sperm. Oh God it feels so good! Oh shit! Fuck yeah!” Jen cried out, and then orgasmed her ass off right in front of us.
After Jen came back down to earth (orgasmically-speaking), Pam cautioned her, “Okay, baby. Now, put your hands around Rex’s rear end, and pull his pelvis towards yours. You’ve got to hold his pubic mound snugly up against your own pussy, so that he can’t pull out of you. I mean, you watched me fuck Rex earlier, right? Just do exactly what you saw me do.
“But you’ll need to stay coupled up with Rex like that for at least 5 to 10 minutes or so. That way, his knot will have time to shrink back down enough so that he won’t injure your little stretched-out vagina when he tries to suddenly pull out of you, because that what male dogs instinctively do when when they’ve finished breeding a bitch. And in this case, you’re Rex’s bitch right now.”
“God, Rex’s knot is still growing bigger inside me! I can barely stand it! It feels like it’s gonna rip me wide open at any moment! But it also feels absolutely incredible to me at the same time! And I don’t want him to pull it out of me! Shit! I’m cumming again!” Jen announced, and proceeded to do just that.
“Don’t let Rex pull out of you yet, sweetie!” Pam warned Jen strongly, while Jen had her eyes closed, as she was caught up in her own orgasmic sensations.
Then Pam shifted her attention back to me, “So I guess it’s your turn to cum now.”
“I can’t compete with your dog, and his buckets of cum, and that big dick-knot of his, but–”
“You don’t have to compete, my dear,” Pam said, cutting me off mid-sentence. “You’ve got the one thing that really turns me on the most. And it’s something that Rex will never have.”
“Oh, yeah? And what’s that?”
“The ability to get me pregnant,” Pam replied. “Why else would I bother going out and picking up men and letting them fuck me, when I’ve got Rex right here with me, ready to service me whenever I want?”
“Is that what I’m doing right now? Getting you pregnant?” I asked coyly.
“I certainly hope so. If not, a girl can always fantasize, can’t she?” Pam said teasingly.
“So can a guy,” I said right back to her.
And just moments later, I began ejaculating my human sperm–adding it to Rex’s previously-ejaculated doggie-sperm–deep inside of Pam’s sexy baby-making hole.
Meanwhile, Jen was still holding onto Rex to try to keep his swollen penis inside her vagina. But Rex kept squirming around, and finally managed to pull his knotted-up doggie-dick out of Jen’s vagina.
And when he did that, it made a single fairly-loud popping sound, like a cork being pulled out of a bottle.
Pam reacted, asking Jen, “Oh my God, Jen! Are you okay?”
“Yeah,” Jen replied. “I think I’ll live. But I’ve never had my vagina stretched like that. The strange thing was that once I got over the initial shock of it all, Rex’s knot didn’t hurt. In fact, it felt fucking awesome to me! His huge knot just kept making me cum over and over again, and I didn’t want him to pull out.”
“Now you see why I love letting Rex fuck me,” Pam said. “You know you’re welcome to let him fuck you too, anytime you’re in the mood for a good fucking.”
“Thanks, Pam. You’re a true friend,” Jen responded, and then turned her attention towards me.
“Okay, Gary. Pam and I have done everything that you wanted us to do. Now, please delete that fucking video of yours,” Jen pleaded.
“Not a chance, sis. I promise I’ll never show it to anyone else, or post it online–but only if you guys keep playing nice, and let me have sex with you whenever I want to. Remember, I’m a super-horny college freshman, and I don’t have any girlfriends here on this campus.”
“I’d be honored to be your girlfriend, Gary, if you’ll have me,” Pam unexpectedly offered, and I could tell she was serious about her offer.
Pam caught me totally off guard with that statement. And for a moment, I just looked at her, not really knowing how I should respond to her offer.
And that’s when I realized–to my sheer horror, I might add–that with Pam, it wasn’t just about the sex, like it was with Jen. It was a much more emotional and deeper experience than that. I was actually starting to have romantic feelings for Pam. But of course, I also didn’t want to give up having sex with my sister, just to become Pam’s boyfriend.
I finally responded to Pam, “That’s sweet and very flattering, Pam. And I would love to accept your offer, because I really do like you a lot, as a person. But are you okay with me continuing to fuck Jen every so often, after you and I become boyfriend and girlfriend?”
“Only if you’re okay with me continuing to fuck Rex when you’re not around,” Pam said matter-of-factly. “‘Cuz there’s no way I’m giving up that awesome doggie-dick of his.”
“I don’t blame you. But I’d prefer it if you’d also fuck Rex when I am around too, so that I can participate in some of the fun.”
“Wow, you really are a pervert, aren’t you? What have I gotten myself into?”
“Hopefully, a mutually-beneficial relationship between you, me, and Rex,” I answered.
“I know that Rex loves me unconditionally. Do you think you can do that? Can you be my knight in shining armor?”
“I can sure give it a hell of a try. At least, with me around, you won’t have to have one-night stands with other guys anymore, just to feel a human penis inside your vagina. Because I’ll be happy to ‘service you’ anytime, Pam.
“And we can even go out on dates to some nice places. I’m not ashamed to hold your hand in public, or call you my girlfriend, if that’s what you’re wanting. And only you and I and Jen will know the true relationship that we all have together that started tonight in this bedroom. What do you say?”
“I’d really like that,” Pam said very softly.
I took Pam by the hand and led her to her bedroom, where I got into bed with her under the covers, and slept with her that night.
The very next morning, Pam made the most incredible eggs Benedict breakfast for me, and we both got along splendidly. That girl could cook her ass off, which was a definite plus if she was going to be my girlfriend from now on, because I was a terrible cook.
It was Sunday, and so there were no classes that day, which meant that it was time for Round 2 in the bedroom with Pam. And she was more than eager and ready to get going. She grabbed me by the hand and took me to her bedroom, before closing and locking the bedroom door behind us. Rex was lying in his circular-shaped doggie bed on the floor across from the foot of the bed.
This time, after Pam and I both got naked, we spent several minutes making out and French-kissing on top of her bed.
Then I said to Pam, “Remember when I told you last night that I wanted to join in the fun if you were ever having sex with Rex when I was around?”
“Yeah,” Pam said, while she was squeezing and playing with my stiffening dick. “So what exactly are you suggesting that we do?”
“Well, I want you to get Rex up on top of the bed with us, and let him lick your pussy in front of me for a while.”
“Sure, that’s no problem,” Pam said, and then turned her attention to Rex, as she told him, “Come on up here, boy. Mommy needs you to clean up her pussy.”
And when Rex heard Pam say the word “pussy,’ he immediately jumped up on top of the bed with his tail wagging. He quickly got between Pam’s legs, stuck his muzzle into her crotch, and began licking and sniffing away at her pussy, as if the taste and smell of Pam’s pussy was some sort of aphrodisiac.
And for Rex, it apparently was, because I saw his reddish-color doggie-dick start emerging from the furry sheath that normally hid his slick, bare-skinned doggie-penis from view–all except for the very tip of it, that is.
“Just let me know when you want him to stop,” Pam said after a few minutes had passed. “Because it feels so good to me when he’s doing this to me that I could literally let him lick me down there for hours.”
“Okay, I think he’s got a doggie hard-on already,” I announced to her.
“I’m pretty sure you’re right, because it usually doesn’t take very long at all for Rex to get ‘in the mood’ once he starts licking my pussy. Notice how he’s trying to hump my leg now.”
“Well, stop him from licking you, and get him to flip over onto his back, so that we can take turns touching and feeling out his doggie-dick,” I suggested to Pam. “And eventually, I’d like to jack him off and make him cum right in front of you, and then fuck the crap out of you afterwards. How’s that sound to you?”
“That sounds good, except that I’d like to add something else. Rex really likes getting his dick sucked. And so I want us to take turns doing that too, before you jack him off in front of me, and then fuck me. Are you good with that?”
“Fucking ‘A’!” I said.
“Okay, baby,” Pam said to Rex. “Mommy’s cleaned up enough now. Would you like a tummy rub?”
And upon hearing the phrase “tummy rub,” Rex flipped over onto his back, with his erect penis pointing up into the air, and Pam began scratching and petting his lower abdomen and his chest.
“Will he let me touch his dick now?” I asked Pam.
“It might be better if you let me touch it first, before you do, since he’s used to me playing with his junk.”
“What about his balls? Is he okay with having his balls touched and played with?”
“Sure. Just as long as you’re gentle them–just like you would be with your own balls.”
Pam didn’t say a word to Rex. Instead, while she was rubbing the dog’s lower abdomen, she simply slid her hand over to the middle and began gently squeezing his furry sheath between her fingers, as well as moving it slightly up and down his reddish-skinned dick-shaft, which he really seemed to enjoy, because he was wagging his tail across the bed. Not only that, but Rex also didn’t make any attempts to try to escape Pam’s adept fondling of his dick.
“Wow!” I remarked. “You’ve got him really well-trained. I can’t believe he’s just lying there and letting you do that to him.”
“Well, it just goes to show you that you can teach an old dog new tricks. You just have to let him lick your pussy for a little while first. That’s all,” Pam said, and we both laughed at her twisted, bizarre sense of humor.
