Take a little break, see how things develop.

The next day, I'm feeling so good, I don't even jack off. Who needs it? I don't need to do that for myself anymore!

The day after that, I regret not jerking off. I'm too horny to concentrate on any of my classes. Maybe a little self maintenance is in order. Sure, I could call Binita over at any time, but I seriously don't want her thinking she's my girlfriend, not even a domesticated one. It would honestly be easier to have her around if she could see me with other, hotter women so she'd know her place.

By the last class of the day, I'm a little frustrated, and looking around at all the hot girls in the lecture hall is both great and annoying. I'm still trying to figure out a way to get any particular girl to get the app, sign up, and swipe right on me before anyone else, but I haven't come up with anything good. Then Caitlin comes in.

Phil, the guy next to me, leans over and says, "Hey, Prof. Barnes is dressed nice today!"

He's right. Instead of her usual frumpy jacket and lumpy skirt, she has on a bright yellow blouse that almost fits and a flowery skirt that barely goes halfway down her shins. She even has her hair down. It's not what I'd call sexy, but it's a huge improvement.

She looks up at me, then pulls out her phone. A second later I get a message. "Is this what you had in mind?"

I write back. "Fuck no. Do better next time."

I can see her frustration when she reads the message. Everyone can, she's standing on a stage in front of an audience, but only I know why she looks like that. She writes back, "Okay."

I send her another message. "Did you do your chores last night?"

"Yes."

"Do you have any pictures of me other than my profile pic?"

There's a pause. "No."

"Take pictures of me when you get the chance."

She looks up at me, and I nod to show that I'm serious. She tilts her phone a little bit, clearly trying to hide the fact that she's taking a picture of a student. Then the bell rings, and she starts her lecture.

"Hi, everyone!" she says with a huge smile. "Today we're going to be talking about... shipbuilding!"

"Whoa, somebody is on new meds," says Phil.

She's like a cheerleader. Big smiles, lots of enthusiasm, and every bit of it looks fake and ****. At several points in the lecture, she says something a little too enthusiastically and the students just burst out laughing. She even took my suggestion to have some slides for her lecture. It's amateurish as hell, but it's still a big improvement over her usual boring lecture.

At a couple of points, she asks us to all open our books to a certain page, so we all have to look down at our desks for a moment. Out of the corner of my eye, I see her taking out her phone and pointing it at me. She even moves to different corners of the stage so she can get different shots of me.

Perfect. It's not just that I want her to have lots of spank material for her nightly edge sessions. After we do this a few more classes, her phone is going to be full of pictures of me, most of which will look like they were taken when I wasn't looking. That's just another thing that will support my version of the story and get her in trouble if she reports anything and the police investigate.

Now, you might be thinking that I'm screwed if the police ever look at her phone because they'll read all the messages I sent her. Well, those weren't text messages, they were through the Ultimate Dating App's chat function. That's locked except to the user, and I seriously doubt a magic ****-making app is going to release their records to the police.

When I get home that evening, I get a message from Binita. It says, "can I come over? please? please can the slut have some cock?"

I think about it for a second, then write, "You can come over when you have a maid uniform."

The next message comes back immediately. "french maid?"

"Fuck no! I'm saving that for when I have someone hotter. You're more like hotel maid level of hot."

There's about a three minute pause. "ordered it. will take couple days"

I smile at that. That should be fun. A few hours later, when it's getting close to bedtime, a picture comes in. It's Caitlin, in bed, wearing some very plain pajamas. She has her hand down her pajama pants, and she's clearly sweating. Her hair is messy, too. She's been at this for awhile. I didn't even have to prompt her for this picture, she just sent it on her own! I need to respond.

"Good girl! I'm glad to see you keeping your promises."

I jack myself off to that picture.

The next night I get an even better picture. Caitlin has her pajama bottoms off, and her hands are inside her panties. Yes, they're big granny panties, no surprise there, but she still has great legs.

I send her a message. "You desperately need new panties. Get something sexy."

"Okay."

"Buy some tomorrow. And if you haven't yet, get some sexier clothes for class."

"Okay."

For being a professor, she's not a great writer.

The next day, I wait before class in anticipation to see what she 's wearing. I grin like a wolf when she walks into the classroom. Her white blouse is tight, fitted around her slender waist. Her red skirt stops just above the knees, and she's even got on heals. Still not a sexy bunny, still within university standards, but I'm not the only guy who notices that she's showing off her slim figure and long legs. I look around the room and see lots of guys suddenly sitting up straight in their seats.

Her lecture is a little better today, still enthusiastic, but less ****. She's getting practice! Obviously I don't take any notes, why the fuck would I? I know I'm gonna get an A in this class.

Caitlin sneaks a few more pictures of me during class. Honestly, probably more than she needs to. When class is over, I wink at her on the way out. She blushes and looks down at the floor. Several students thank her for the great lecture as they leave. They should be thanking me!

As I start to walk back to my apartment, I get a message.
