Dominantly

You stroke yourself through your pants as you think, and watch your professor get increasingly turned on. Her hands are now pistoning desperately in and out of her pussy, shaking her boobs and and waving her long hair around her body. Her eyes are locked on your eyes, and she's biting her lip, all of which nearly sends you over the edge but you stop yourself and think of a way to potentially increase her pleasure while asserting control over the situation.

While continuing to touch yourself lightly, you slowly approach her around the desk and say, "Fuck, you're gorgeous. But in most student teacher relationships, everything is either built around the teacher being the dominant one or the teacher having the power due to grades. Would you rather keep our relatively equal dynamic, or let me have all the power and dominance in our relationship?"

You've now reached her chair and run your fingers through her hair and she cums just from the implications of the question, then gasps out, "Give you all the power." Your dick throbs as you think about how you were able to completely change your professors perspective with a few questions and phrases. Meanwhile she turns and you again see the need in her face as she throws herself out of the chair and into your embrace, grinding on your dick while shoving her tongue into your mouth in a drawn out kiss.

You let this go on for awhile, then feel you are about to cum and gently push her away. She looks at you with some shock and dismay and starts to say "Wait, I-"

"Stop, don't talk for now," you say, getting into your new role, "lay on the couch, remove the rest of your clothes and touch yourself, but don't let yourself cum." She doesn't really want to but complies, getting turned on even more due to doing what you say. You watch her big boobs and body jiggle enticenly and touch yourself.

You let this go on for a few minutes, and her moans continue to intensify as she thrusts her body harder and harder into her hands, still preventing herself from cumming. Finally, you sit in her chair and simply say, "ride me."

She immediately gets up and runs to you, then straddles your cock and starts to ride it with abandon. You feel every movement of her hips clapping against yours and every sensation from her tight pussy, and feel yourself getting close. You say, "Get off and use your mouth to finish me off, then hold my cum in it." She momentarily looks dissapointed, but as she gets off of you and on her knees she shudders from a rush of pleasure, then lowers her head and hungrily bobs on your dick. "Cum when I do," you say.

Shortly after she starts you're cumming in her mouth, and you feel her body shuddering in her own orgasm between your legs. You look down at her and see that she is looking at you with her mouth tightly shut, but that doing so is arousing her yet again. She starts to move her hands to touch herself, but you say, "Don't touch yourself for now, we're done. You're going to have to control yourself to keep this secret, especially in public." Her face falls but she nods her head, and you see her continue to squirm in a more muted way. Her face gets redder as well, and you can see that even though she likes this, she is still herself and feels some amount of embarasment and guilt.

You see a drop of your cum fall from her lips and say, "Would you rather hold my cum in your mouth for the next hour or spit it onto your tits, rub it around gently, and keep it there without washing yourself for the rest of the day?"

She gets more red and appears a little mortified, but you can tell that your question still aroused her as she tilts her head up in order to carefully say,"Tits." You watch and feel your limp dick slightly twitch as she does what you wanted, but as she goes to get dressed you say, "Oh, and don't wear a bra for the rest of today."

She looks at you and gets a little mad and embarrassed, and says, "Hey, that's not fair!"

You just chuckle and say, "Does it matter?"

"I guess not," she says, somewhat sullenly, "but still." She finishes getting dressed and you can just see her wetter tits through her blouse, free from constraint.

You stop to think more clearly for a moment, start to feel really guilty, and contemplate undoing at least some of what you've done. But you reason that she likes this now, and that you're happy with it, and decide to leave it for now at least. You get ready to leave and she sits back in her chair, then asks, "When will I see you next?"

"Either when I want or when I decide to come to class," you reply. "Until then, don't change your behavior outside of whatever I tell you to do. I'm off for a bit and I may see your student Terra in an unprofessional way later, but we'll see."

Her body shakes with sudden arousal, but she stops herself from doing anything and says,"We do have an open relationship, and I'd love for that to happen anyways. Thanks for stopping by!"

"Of course, bye." You leave her office and stop in the hall, thinking about what to do now.
