Of course, there is no stopping now

I came down from my orgasm, my ass still tightly clenching to the dildo as the waves of my orgasm continued. I reach down to take the dildo out of my ass, but Sarah stops me. "No, that needs to stay where it is. It might hurt a little now to keep it there, but it will make the whole process easier. Come, lie with me, let's take a breather, before the real show starts."

I lie next to her, licking my lips to clear it of her cum. She reaches out and scoops up a little of the leftovers on my face and puts it into her mouth. She smiles, "I like the taste of cum." I look at her pretty face and ask about her sex life. "This can't be your first time. You seem to have skills with your mouth and know just what you are doing." She replies, "No, it's not my first time, but I don't have as much experience as you might think. There aren't that many boys in my town who would be okay with being penetrated by a penis and those that would, don't like my female figure. Perhaps it seems like I know what I am doing because, a, I know what I want, very much so. And b, because I have had to train myself as well. While I may not have been able to find boys who would let me fuck them, which is what I like. There were plenty who were happy to fill my holes with their own cocks. But now, I have you here and you seem eager to take my dick however it comes and I am all too happy to share it with you."

She then wonders about me, "You said that you have not done more than a prostate toy, yet you seem to really take to being a cocksucker and I think you are gonna make a great cock slut. Haven't you thought about taking dick before now?"

"Well, I have. I have fantasised about dick off and on, but I was never really into the male form. Penis, yes, men, not so much. So you seem to be the perfect package, a very feminine form, but a very powerful cock."

"True enough, I am perfect. It's just not all people see it that way." She smiled wistfully. "Don't you think that you and me fucking like animals is going to be a problems for Anna?"

"It's funny that you should mention Anna, I had been meaning to tell you about what she is up to on her planned trip. She is away looking to get lucky with another woman. So I don't feel too bad about having fun with you. But, I would rather that we had talked about it with her before we got involved. But you made it very difficult to pass up that swinging meat of yours."

Sarah seemed almost confused, but also excited. "Wait, does that mean what I think? Does that mean that Anna might be okay with us fucking? Do you think that she'll let us continue even when she is back?"

"It is a possibility, but I can't see her just letting us fuck each other all day and all night. I think she might want some action too."

Sarah's smile increased even more. "We might actually play all together?"

"I think we will do more than play. I think it will be a fuck-a-thon. But let's leave that for the time being. We can figure out how to share the news with Anna when she gets back. For now, I am interested in getting a little rest. My head is swimming with **** and pleasure."

Sarah didn't like my idea at all. "Perhaps you just need some coffee, because I am far from finished with you tonight. I won't be finished until I have put my dick inside you."

"I don't know how you still have cum in your balls, but I am not 18, I am almost spent."

"Well, luckily for you, you don't need to cum to be the best cock sleeve for me. That's just an added benefit. I can still get my jollies by buttfucking you all night. Anyway, there is a point to that dildo in your ass. It is supposed to be preparing you for the real deal.
