Hina twirled her short pink hair around her finger, glancing shyly up at you with her rosy eyes. She had been your girlfriend for a little over two months now, and even though she was still too nervous to do all the naughty things you really wanted to try together, she was trying her best to make you happy. Hina was just so sweet and innocent, with her huge, perky tits and juicy bubble butt barely contained in her tight blue jeans and little white crop top. She didn't fully understand all the adult stuff yet, but she was eager to learn, even if she was a bit naive about it all.

One day, Hina confided in her best friend Yumi about how she wanted to do something extra special for your upcoming anniversary. "I thought maybe...maybe I could finally give him a blowjob?" Hina said softly, blushing and looking down at her big, soft tits barely covered by her thin top. Yumi's eyes widened and she grinned mischievously when she heard Hina's naive plan.

"He's gonna love that, Hina! But I bet you've never done one before, right?" Yumi asked, knowing her sweet friend was still a virgin. Hina shook her head no, sending her short pink bob hair swishing around her pink eyes.

That's when school playboy Roy stepped in. He had been listening in on their girly gossip, always on the lookout for his next conquest. Roy put a hand on Yumi's shoulder and flashed his most charming grin. "Hey, if Hina here wants to learn, maybe I could help her out. Give her some pointers, ya know?" he said with a wink.

Hina just blinked her pink eyes innocently, not fully grasping Roy's ulterior motives. "Oh, um, I guess that could work..." she murmured, as Yumi elbowed her and nodded eagerly, thinking it was a great idea without considering Hina already had a boyfriend.

So for a whole week after school, Hina would sneak off to meet Roy in his dorm room. He taught her how to use her tongue and lips the way he liked, not caring she was just practicing for you. Hina was always eager to learn and please her new teacher, never once considering she was being unfaithful to your relationship. She just didn't understand.

Finally, the day of your 3 month anniversary arrived. Hina had been nervous all day, thinking about surprising you with her new blowjob skills she had learned from Roy. That night, after dinner, she turned to you with shining pink eyes and a shy smile on her cute face.

"Sweetie, I have a special anniversary present for you," Hina said softly, sinking to her knees in front of you on the couch. She looked up at you with trusting eyes as her little hands reached for your belt buckle. "I practiced all week so I can make you feel really good tonight. I think you'll love it!" Hina declared naively, having no idea the grave mistake she had been making. She gazed at you with love and excitement, not grasping the gravity of her infidelity as she began to unbuckle your pants.
