Ask her what she means

You lift her head to look at you. "Nicole, you've been my best friend for a long time, and now we're lovers," you say, smiling at her. "What are you talking about? What's a submissive? Are you talking about a sex ****?"

Nicole smiles at you. "Of course you don't know. That's so sweet!" She puts her arms around you and hugs you, laying a fat kiss on your lips. She breaks the kiss after a couple minutes.

She looks at you a little embarrassed. "I'm a little weird. I find certain kinds of pain very pleasurable. I'm what you call a pain slut. When you spanked me, it felt so good, I would have had an orgasm just from the pain." Nicole shivers and moans for a second, lost in the memory. She opens her eyes again. "I'm a bottom, meaning that I'm the receptive partner in whatever it is that we're doing. If you're the top, then you would be the active partner, the one who does things to the bottom." She wiggles on your lap.

"What kinds of things?" you ask, images swirling in your head.

"Mmmm, well, tying me up, spanking me, whipping maybe. You know, kinky things. Or we can just have rough sex. How does that sound to you?" Nicole asks.

"I don't know much about that stuff," you reply.

"That's okay. I'll show you. There's books and DVDs and stuff." She beams at you. "We'll have a sort of Kinky college!"

"Is this why you were with Tony? Cuz he knocked you around?"

"Sort of. He started out okay, but I never told him about me. He just started hurting me for no reason. He just got angrier and angrier. He got jealous when I talked to the cashier at the grocery store. He was out of control. What I'm asking for is for you to do good things to me that happen to cause pain, not bad things. Are you in?

"So, I can tie you up, spank you, and make you do things?" You get a big grin on your face. "I don't want to punch you, I want to love you. I'm in!"

Nicole kisses you deeply, her tongue whipping around rapidly in your mouth. Then she moves down and swallows your cock again. Her mouth feels so fine.
