Page 40 of Good Girl

“What are you doing?” This was so incredibly risky for both our sakes, and Matt had made it clear how Derek was supposed to be keeping his nose clean. I told myself I was the exception so long as we didn’t get caught.

“I don’t like it when I hear about othermenbeing near you,” Derek growled softly, and with his attempts to keep his calm voice low, it was an incredibly sexy sound. Suddenly, his fingers brushed under my skirt and stroked up my thigh as he spoke.

“Other guys?” I asked. Confusion swirled in my chest, and a tight band constricted around my next breath. Derek dipped from my view, and I clutched at the shelving behind me as he pulled my underwear down. I was too excited to be touched to care about getting caught right now, and the confusion was a small distraction.

“Do you mean Matt?” Did Derek know what Matt and I had done on his motorcycle? Of course he did. They seemed to tell each other everything, but I had no idea that Matt was off limits. Were Derek and I supposed to be exclusive? No, surely not with what we’ve been doing.

A small, cold, oval shaped item was abruptly shoved inside my pussy, and I squealed softly at the intrusion. The item was sealed with a kiss from Derek, and heat flushed through me, head to toe, then he pulled my underwear back up and rose to face me.

“Not Matt,” Derek clarified. “Jonathan. Your weasel of an ex.”

Oh, that made a lot more sense.

“My friends are fine. We’ll be training you together, but when I decide to train someone, I expect their full dedication, no distraction.” Derek’s strong fingers gripped my jaw, and my heart skipped a beat.

“You have it,” I insisted. “Jonathan is no one. Nothing. But what did you put inside me?”

“Just a little treat.” Derek smirked. “It’ll keep you occupied.”

It was an odd sensation, having something solid inside me like that, and I shifted my stance, trying to work out how it wouldn’t fall out of me the moment I started walking. It seemed somewhat snug. My mind then latched onto something else Derek said, and I lifted my gaze to his.

“Train me? For what?”

“To be a good girl, of course.”

“Ihatethat,” I groaned softly. “I want to be a bad girl.”

“My apologies.” Derek grinned. “My obedientpet. Better?”

I nodded quickly, and Derek leaned forward, pressing a chaste kiss to my forehead. When he leaned back, there was a small black remote in his hand. He pushed the white cross button, and the toy inside me suddenly began to vibrate. I squeaked and slapped a hand over my mouth.

“I expect you to have better control in class, and under no circumstances are you to give in to the pleasure until I tell you to,” Derek murmured, and with that, he left. The door closed softly behind him, and I was stuck, knees trembling, as gentle vibrations swept relentlessly through my core. How was I supposed to stay focused like this?

Class became an over-heated, trembling nightmare. I had hoped that being seated would give me more control over dealing with the toy, but sitting down had the toy pressing hard against an exciting bundle of nerves inside me that I didn’t know existed. The vibrations were low enough that I couldn’t hear anything, but they kept me creeping painfully slowly toward an orgasm that I was holding off with every ounce of focus I had. Derek taunted me from the front of the class, holding the toy remote in his hand while he gave a lecture that I didn’t hear a word of. Every so often, the toy would increase the force of its vibrations, and I would lift my gaze to see Derek staring directly at me. The toy would buzz for as long as I held eye contact, then it would fall away.

It was the one class I was grateful that Haley was on her phone the entire time and didn’t pay me any attention. She would glance at me every so often as I hunched over my desk and furiously typed worthless notes to try and distract myself, but not a word was spoken.

I had never been so relieved to hear the bell ring, signaling the end of the lecture. My heart was pounding, my entire body trembling faintly, and my panties were soaked. I lingered, putting my stuff away slowly because I didn’t trust myself to stand. Haley didn’t wait for me, of course. She swanned out of class the moment the bell struck, and I waited until the lecture hall was empty before I approached Derek.

“How do you feel?” he asked the second I stepped onto the stage.

“Horny,” I replied breathlessly, and my cheeks flared.

“This was punishment for not telling me about Jonathan.”

“I didn’t ever expect to see him here,” I replied, fighting not to squirm where I stood. “I broke up with him before I even came here.”

“I understand.” Derek began to slowly walk toward me. “Are there any other exes that I should be concerned about?”

“No, there’s no one.”

“Do you think you deserve to come?” He stopped in front of me, staring down with those dark eyes that might as well have been the cross brace of my puppet strings.

“Yes,” I replied instantly, fueled by the warm ache between my legs. Then again, Derek had laid out that this was a punishment, and I should have told him about Jonathan, especially since he had been texting me long before that meeting.

“No,” I decided, and I bit back a whimper. If nothing else, maybe Derek would at least turn off the damn toy. Derek smirked down at me, then he sank to his knees and disappeared under my skirt. With nothing to hold onto, I could only clutch at the material of my long skirt and whimper when Derek’s hot breath ghosted over my thighs.

Suddenly, his hot tongue pressed flat against my soaked panties, applying some much-desired pressure to my clit, and I choked out a weak moan. I didn’t care that someone could walk in, I didn’t care that I wasn’t allowed to come. The moment Derek licked at me, I lost control.
