Ask a few questions...

While you stood there toweling off after your shower, you decided to ask her a few questions.

"So," you say, as you dry off, "how often CAN you cum?"

"As often as a normal girl can, I think." She looks at you seductively. "Why...do you have the need to fuck again?"

You feel tired, spent. As you use the towel to dry off your legs, you notice a stream of cum running down them from your asshole. She looks at you expectantly. "Uh, I really don't, but if you want to again, you can use your cum as lube." You gesture to your asshole.

She says, "I am here for you, if you do not want to, we don't have to."

You feel a pang of guilt for some reason, or perhaps just a spasm from your previous fuck. "No, go ahead, I want you to," you say with a sigh.

She breaks into a huge grin and leads you back to the bedroom. She has you lay down on your back, and inserts her huge cock into your ass right away. It's a bit less pleseant than last time, because of the soreness, but her gallon of cum has you lubed up all the way inside, and she slides in without any discomfort. This time, as she fucks you, you begin to get used to it rather quickly, and before you know it, you barely notice the 10" cock in your ass at all. You smile at the achievement.

"Enjoying this, are we?" she pants as she fucks you to her heart's content.

"I am because you are," you reply.

"Hey, want to try something different?" she asks suddenly. She doesn't wait for a reply, but twists around with her cock still in your ass, until she is sort of at an angle upside down. She is now trying to keep her cock in your ass, while she moves her big bubble butt to impale herself on your cock which has been starving for attention this whole time. You get really excited when you see what she is trying to attempt. She ends up being just a few inches short. "Damn, I thought I was big enough now." She sees your disappointed look. "Wait, stick your finger up my ass and move it how I tell you. There's a little secret I have."

You do as she says: in, a bit to the right, and then push hard. She moans and starts to slowly continue her attempt to keep her cock in your ass while moving her ass back to get you inside her. "Keep at it...that's a little factory trick the designers use to adjust us just right. I just wonder how much 'adjusting' it can do!" Her cock continues to slowly grow, it must be 14" by now. It must also be getting wider now, as you feel pressure on your asshole again.

After a minute or so more, and estimating it at a bit over 15", she slides that big beautiful ass over your cock, being careful to keep her thick cock still inside you. You guide her big ass down as you fondle and squeeze it. She uses her hand to fuck her cock in and out of your asshole as she urges you to fuck hers.

"By the way, this increased size is going to make me extra sensitive for awhile, and cause me to cum more," she gestures to her balls, which tripled in size. "I...I'm cumming!" She yells out suddenly after just a few seconds. You feel her ass contract but dont feel any more cum in your ass. Just as you begin to wonder...it starts. Cum fills your ass rapidly, and some begins to leak out around her cock. But there is so much...you feel a few sensation as cum flows UP your bowels, since it has nowhere else to go. She cums for a few minutes straight, and you revel in the new feeling and take pride in being able to handle all her cum. Of course, in the middle of this, you let loose in her ass. You cum more than normal for yourself...strange since you already came so many times today. She loves it and makes you feel as if you are cumming as much as she is. "Ooooh, I'm so full, I can't take anymore, you are overfilling me!"

After she stops pumping up your ass, she withdraws and watches the cum flood out. She quickly grabs a large buttplug to hold it in. "Save it to lube you up for next time," she says with a grin, "or me!"

"So, that was exciting, anything else kinky you want to try?"
