She wants to chat and get herself off

"I'd like to have a chat. And, um... I'm hoping that you might get me to do something." She looks a bit shy.

"What do you mean, Amy?" You ask.

Amy looks at you in frustration. "You're the one in control, doofus," she says, reaching down between her legs. "I can take care of myself if I have to, but I'd like it better if it's interactive somehow. With some form of contact.... and, you're getting soft."

You come to realise that, even though the two of you have just fucked, it's mostly because she is free for you to have fun with. It doesn't go the other way around. "Right, right. Um, why don't you get yourself off by rubbing your pussy against my leg?"

Amy smiles. "That's more like it," she says. She stands up, and lets your penis pop wetly out from her sex. She turns around, and straddles your knee. You move forward to give her more leg to sit on, and she moves her cunt forward. Your combined juices ooze out of her onto your leg and the chair, and Amy bounces lightly on it.

She looks to you. "So, I'm pretty sure you were trying to make this happen, John. I want to let you know that I decided to let it happen."

You feel a bit chastened, but decide to carry on. "Why did you do that?"

She pants a little. "Partly the situation with Chris. I decided that I was a bit jealous of the attention that the sluts at his work get. Maybe now, I'll get a bit of attention in the morning."

"But that's not all?" you ask her.

"Well... the night you set up reminded me a lot of college. You might remember I was a bit bigger on top then? Probably from the beer and pizza," she giggled. "Sex was a bit more of a haze back then. Even now, with me rubbing my pussy against your leg, it feels good, but vague. Chatting with other girls, it's like we don't feel good, or anxious, or anything about any one thing people do with us. Instead it's about all the things happening all the time. I missed that."

"So... you're fine that I came in your mouth without asking?"

Amy smiled. "Well, yeah! It's nice to wake up feeling loved like that. I mean, it's a good thing that you checked that I was DD first. I probably would have felt really weird and tense about it if you had done it yesterday. Things are much easier when I'm like this: it just feels right. So long as I'm bigger on top you can use me however you like. I hope you'll play nice," she said, squeezing her tits together for my benefit.

"Why not just have an affair?" you ask her. "I mean, this way you'll be fair game for anyone."

Amy shrugs, her breasts jiggling. "Affairs are tense and complicated. This is easier: no-one's feelings get hurt if someone decides to have their way with some big-titted slut. And I'm hoping..." she said, drawing things out, "that you will help look out for me as long as I'm busty. Be a good friend," she says, looking at me meaningfully, grasping a breast.

You take the hint, and grasp her other breast. She gasps. "Mmmmm, yeah," she says.

"Do you plan on keeping yourself... big?" you ask.

Amy shrugs. "I don't know. Maybe this is a passing whim, maybe I'll just go through another big-titted phase. I think it will depend on how things go."
