[AI Mosaic Used x 6K Filming] Groundbreaking ultra-high resolution (5760×2880). With future international expansion in mind, a business English conversation program has been introduced at my workplace. According to the executive who arranged it, they’ve specially brought in one carefully selected native instructor from overseas for serious, professional training. As someone who’s completely hopeless at English, I arrived on the day feeling gloomy… but then she appeared—the instructor was a stunning foreign beauty. "She’s so gorgeous… and incredibly sexy… this is only making me more nervous!" I thought, as the lesson began. Predictably, I performed terribly. Yet she kindly reassured me, saying, "Don’t panic, it’s okay. Do you have time for more practice?" and offered to stay behind for extra tutoring. Whenever I managed to speak correctly, she’d light up with joy and praise me. "She’s so cute," I thought, completely captivated—when suddenly, she kissed my cheek and hugged me tightly. As I froze in shock, she leaned in again, asking, "Can I kiss you?" and without waiting for my answer, gave me a deep, passionate tongue kiss. "U-uhh…" Realizing my erection, she pushed me down and took full control. Before I knew it, my pants were off and she was passionately sucking my cock, smirking with a mischievous, devilish grin as I neared climax. Completely turned on, she stripped, exposed her breasts, drooled while masturbating, and gave me a blowjob while provocatively showing off her ass—doing whatever she pleased. After I thoroughly licked her pussy, she mounted me in cowgirl position, grinding in rolling motions to let me enjoy her breasts, then switched to rear cowgirl so I could savor her ass. As we switched to face-to-face sitting and missionary, delighting in her cute expressions, she told me she’d make me cum in her mouth. "Wait… why am I suddenly understanding English?!" I wondered, as I erupted in thick spurts into her warm, soft mouth. She swallowed it all with pleasure and whispered a secret: "The best English lesson is sex◆."
