After studying on the textbook for long and tedious hours, I finally get the hang of it. But, it cost me a little bit of sleep. Thankfully, I took a shot of hot coffee some mare left me in the morning at my table before I left. Now for some reason, someone else who knew Bubbly Shouts wants to milk me out too. Until then, I have probably a sign language pop quiz to worry about, or whatever.

"Please don't give me a pop quiz..." I prayed.

"Pop Quiz!" someone chirped in cuteness. I wanted to bump my head on something, but it isn't worth it. I saw as Silent Storm smiled with her hands behind her back and swaying her body slowly, while Lime Squeeze wrapped her arms around my shoulders.

"Three guesses to what she's signing." Lime whispered in my ear. I gulped as I saw Silent sign vigorously, and I had to watch her hands and translate in my mind the best way I could. I tried looking at her face, but I couldn't get a hint out of her except her tongue on her upper lip in light lust. Once she finished signing, she put her hand on her hips with a smirk. I took my time to translate, but took a hard guess in nervousness.

"Ummm... How did I sleep? Did I have breakfast? Did I get a hard-on?" I answered. Lime closed her mouth, trying not to giggle.

"You have a test tomorrow, so you'll have to study twice as hard. In the meantime, let's be study buddies!" Lime corrected as we walked to class. I nodded without question, but cried on the inside.

As I entered the classroom, I saw as Soundless clearing the board, and mature Earth talking with her and taking her leave afterwards. After sitting in my seat, I heard the class coming in and taking in their seats, wondering what their assignment are next. Soundless finished and walked to us before grabbing our attention.

"Okay, class," she announced. "I assumed that you have studied our pages from last night, so we'll have to have a pop quiz to see if you have. As for Mojo..."

I gulped after hearing, but I didn't bother looking at anyone else but Soundless. Some of the mares snuck a look at me with either sultry eyes or bitten lips, while others whispered secrets to one another. The professor asked me to approach the desk and I obeyed. Once I came close to Soundless, she took a look down and went up to my face before passing me a piece of paper with a note on it. It contained some signing pictures and below them read, "You'll do everything I say", "Good mare...", "Do you want it?", "Say it!", and "I love it".

"While I teach my class, study these words, because that will be for your final exam. Okay?" Soundless suggested. I nodded before going back to my seat. While everyone paid attention to the professor, I started looking at the notes and studied, taking my chances at learning sign language with these phrases. Of course, I hope that no mares start glancing at me...

After class, I finally left to get some water. However, I was pulled in by Crystal Rockies, who felt a little pissed off.

"Hey, Hey, Hey!" I called. "What the hell's going on?"

"Shut up. Just come with me." Crystal snapped. She pushed the door to a janitor closet and dragged me inside. As soon as she let go of me, she stopped, looking away from me before breathing. I waited for her to even utter a word, but for a few minutes, she just stood there. It was then she breathed deeply and turned to me with a tear in her eye.

"Are you ok?" I asked in wonder.

"I'm sorry that I did this to you," Crystal sobbed lightly before hugging me. "Whatever Bubbly did is beyond me..."

"But, you watched me and Bubbly..." I retorted.

Crystal let go and put her hands on my shoulders. "I just couldn't stand watching. And even though I did, she was gonna rub it in my face and make me jealous."

I had no idea what to say or do except comfort her, so I had to hug her once more. As soon as her head was on my chest, her crying stopped. Feeling her need of sympathy, I asked if she's ok again, and she answered that she will be soon. It was then I felt her hand rubbing my crotch. I went wide-eyed in shock, which then turned into light arousal. I moved a few steps backwards, but she approached to me closer, never losing sight or touch.

"I only had a taste of you, now I want every inch..." Crystal uttered in lust, giving me a bump in my pants. After playing with my bulge for a few seconds, she paused and came across a chair near the wall.

"Sit down." Crystal demanded, pushing me down to the chair. After that, she stripped me off of my pants and boxers, letting my boner free to stretch. She breathed softly on it before pulling back the skin and licking the tip. After tasting it, she rolled her tongue around it rapidly then sucks the base, cooing in delight. Crystal wasted no time sucking my member without hesitation, and I couldn't help but watch.

"Mmmm... I'm such a little cock slut, huh?..." Crystal said proudly. She continued to suck off my member with vigor. She came back up to the head and rapidly shook her tongue around it, then went back down to the base. Every time she sped up her sucking, she moaned in pleasure. The warmth of her mouth made the sensation uncanny as well as incredible. I came close to a good climax, but she opened her mouth. She then let a load of my seed into her mouth, cooing in delight.

"You like when I suck you off, don't you?..." Crystal smirked proudly. "Well, this isn't over yet, big boy..."

Crystal pulled out my member from her mouth and exposed her round and firm D-cup breasts in front of me. She then placed my still-hard member and placed it between them. After lubing it with her tongue again, she squeezed her breasts and bounced them up and down in a steady pace, gazing at my reaction. The pain of my hardness coming back to work turned to pleasure in a few minutes, but it gets twice as better as she quickened her pace. The softness of her chest and her movements became nothing more than satisfaction, putting me on the edge of release. Despite the fact that I'm still holding on, Crystal wasn't keen on giving up easily, and she expected to finish with a bang. After her several strokes, I groaned in delight as I released. It wasn't long before she quickly sucked my member yet again, letting out the seed in her mouth. Crystal cooed in satisfaction, rubbing it between her lips, and I laid my head slightly back, taking in her success of her fellatio work.

"Better?" I asked.

"Uh-huh." Crystal uttered in a sexually satisfied tone.

"I appreciate your coming in for your final exam... Care to do the honors, stud?... Come and make a pony out of me!..."
