Next day

As promised, "failing" the quest didn't affect our studies or friendship, at least for Emma. The next day, she came to the library and sat across from me as always.

"No new pictures until after Thanksgiving, but you still have to keep tutoring me. That's your punishment," she stated matter-of-factly as she took out her books.

I took a deep breath. "I didn't cheat." I said. "Tonight, I'll send you a full body pic with my cock out to prove it."

"You could just photoshop it. That doesn't prove anything and your lying isn't making things any better." Emma sighed. "Perhaps more punishments are in order."

I was beginning to get angry. "When have you ever known me to cheat or be dishonest?" I hissed. I had been scared of her teasing me about my cock, but her questioning my integrity was somehow even worse.

Emma seemed to consider this for a moment. "Fine. After we're done here, I'll go to your house and you can prove it," she said with a smirk.

I instantly knew what she meant, and almost regretted bringing it up. I was blushing throughout the whole study session and could barely concentrate. Luckily Emma was studying an easy topic and I didn't mess up too much.

After an awkward walk home, I quickly rushed Emma downstairs, not wanting to run into my mom and be bombarded with questions.

"Thanks for still helping me study," Emma said, as we got downstairs. "Look Isaac, if you're so insecure about your dick, we can just forget about it. I'll let you stay on level 1 and we'll go back to the way things were after Thanksgiving."

I was blushing again, but took a deep breath and composed myself. I couldn't believe what I was about to do, but if it was the only way to prove I didn't cheat and get back in the game.... "N-no, let's do this," I said quietly. Before I could have second thoughts, I pulled down my pants, exposing my privates to Emma.

Her eyes widened in surprise, but she quickly recovered. "Well, well. I'm impressed." She took out her phone and opened up the picture I had sent her. "But I need to see it erect to make sure."

"Uh, I'm not sure if I can do it while you're here," I muttered.

"What, you can masturbate to pictures of me, but not in front of the real thing?" Emma asked with a smirk.

When she put it that way, it sounded stupid. But this was the real living, breathing Emma who was looking at my cock, something no picture could do. Even though she was only looking to verify my photo and nothing more, this was still a little too real, and I wasn't sure I was ready for that. I closed my eyes and tried to bring a picture of her to mind, but was distracted by the real Emma's chuckle.

"Here, let me give you a hand," Emma said, giggling at her own joke. I gasped as I felt her soft fingers wrap around my cock. I opened my eyes and met her gaze as she expertly ran her fingers along my shaft. This was the closest she's ever stood to me, and I imagined leaning over to kiss her on the lips even though I knew I would never dare. The moment ended all too soon, and Emma stepped away, looking between her phone and your now erect cock.

"Looks like I owe you an apology," Emma said. "Your cock really is that big. It's probably even bigger than the last one I sucked." You couldn't help welling up with pride, at the same time you were a bit sad hearing her admit to sucking cock so casually. Of course you knew she had given blowjobs and probably slept around, while this is the closest you've ever been to a girl. But you couldn't help wondering how much of the rumors about Emma being a slut were actually true and how many guys she's been with.

"Maybe I can help finish you off to make up for doubting you," Emma said with a seductive smile.
