When Julie casually told me she had never swallowed cum before, I made the joke, "I've never swallowed a load either, well, not yet."
She looked at me coyly. "Oh really? Tell me more."
"It was a joke."
"Well, be that as it may, I'm intrigued. Would you swallow cum?"
"What? You're messing with me, right? You're not going to show up one night with a dude you expect me to blow, are you?"
"That is one option," Julie said, sounding like she liked that idea. "But how about this? You've got a penis. Balls. What about swallowing your own?"
"I can't self-suck. I know; I've tried." I blurted without thinking. Hoping she'd think that too was a joke, I continued, "Although, I've had a few dreams where I could. Such lovely dreams."
Julie laughed. "Ugh, you guys. I bet every one of you has attempted that at some point."
"I did once jerk off into a glass, planning to drink it. But as soon as I came, I lost all desire or interest. No thanks. Why the hell am I telling you this? I should just shut up now."
"Ha, so it wasn't just a joke. You've almost actually done it. You have to do it. I'll help you."
"Julie, I ..."
"We're doing this; you're doing it. You've got me all horny as hell just thinking about it. Seeing your cock erupt, blasting spurts of cum into your mouth." She kissed me and then said, "Please, you never know; you might like it. I know; I will fucking love watching it."
"Dammit, why did I have to open my big mouth and make that stupid joke?"
"Big enough to hold plenty of your cream. Fresh, still warm from the source," she teased. "Then you just have to swallow it. Show me how it's done. In fact, if you do it, I promise I'll do it too. We can both swallow for the first time."
"I don't know; I feel like you're probably just saying that, trying to pressure me to do it," I said, in a feeble attempt to get myself out of the deal. Oh my god, I'm starting to sound like I'm the girlfriend in this relationship.
"Yes," Julie admitted. She smiled at me. We both knew it was happening.
...

Ten minutes later, Julie had me naked, strategically positioned upside down against the wall and headboard of the bed. My cock in her hand, erect and aimed at my mouth. I wasn't sure I'd take all, or any, of the semen in my mouth at this time. I knew I might, at the last moment, chicken out and close my mouth. A cum blast to the face, I was okay with.
Julie tugged on me until the first drop of pre-cum emerged. She fingered it to my tongue. I was surprised at how much I enjoyed both taste and texture. The second larger drop left a string from cock to tongue, and I began to crave a third taste. This was the moment I knew I would take the load in my mouth. I wanted it.
Julie squeezed my balls and milked more pre-cum out of me. It dripped slowly to my tongue. "You love that, don't you?" she said. "Cum for me; let me see streams of cum shoot straight into your waiting mouth."
I was ready. My cock released a series of squirts. Julie's aim was true, and the first shot of my ejaculate hit the back of my throat. It closed as the second, third, fourth, fifth, sixth, and seventh spurts of cum pumped out of my throbbing member into my mouth. It hit my tongue with a pleasant pressure and made a wet noise as the last bursts joined the pool of cum filling my open mouth.
The taste and texture were not as good as the pre-cum. It felt like an entire mouthful. It coated my tongue and teeth and wanted to leak out the sides of my mouth. I closed my mouth. I wanted to spit it out.
"Swallow," Julie said. "Don't you dare spit it out. Do it. Swallow."
I bravely swallowed the gooeyness down. Swallowed again, as the cum and taste seemed to linger in my mouth. Julie shook the last of the cum from my penis, making it drip on my nose and cheek.
"Good job. That was so much fun. Next time I'm going to put lipstick on you first," Julie said enthusiastically. She tenderly kissed my neck. Looked me sincerely in the eyes and asked, "So, you don't seriously still expect me to swallow cum too, do you?" Proudly, she smiled. "See, I can make jokes too."
