My name is Nao, I'm 19 years old. I'm going to tell you about what happened between me and my cousin's older brother on New Year's Day. Around 1 a.m., I was bored, so I went to his room, but he was already asleep. I thought, "This is so boring," so I slipped into his bed. No matter what I did, he wouldn't wake up, so I started playing a prank on him—and gradually, I got turned on. I started rubbing myself against his crotch. Then he finally woke up, and it got kind of awkward. But he gently stroked my head, kissed me, and things slowly got more intense. I was wearing sweatpants with no bra, and he immediately slipped his hand inside, touching me directly. He groped my breasts with both hands, pinching my nipples until they got hard. It felt strange, but really good. Then his hand moved lower. I felt embarrassed and tried to stop him by pressing my hand down, but he asked, "Is this your first time?" I shook my head no, and he said, "It's okay," then traced his fingers along my slit over my clothes. At that point, I couldn't stop anymore. He pulled my pants down, traced my slit again, then slipped a finger inside from the side of my panties. He quickly found my clit and started rubbing it hard. Since my clit is sensitive, I let out a soft moan, "Nngh..." As he pressed and rubbed my clit more intensely, I struggled to stay quiet, worried someone might hear us. But then he said, "Open your legs wider," and started licking my clit—making me cum right there. After that, he sucked on my breasts while inserting fingers into my pussy, aggressively stimulating my G-spot. I felt so good that my hips started moving on their own. Then he guided my hand to his crotch. His cock was already hard. I rubbed it through his clothes, then grabbed it and started moving my hand up and down. I slipped my hand into his pants and started touching it directly—his tip was already wet and slippery. Completely losing control, I pulled his pants down and started sucking his cock. At first slowly, then faster. I couldn't help but let out soft moans. The whole time, I kept rubbing my own clit. I was so wet I surprised myself. He asked, "Can I go in?" I hesitated, but answered, "Only if you have a condom." "I do," he said, pulling one out. Then, after putting it on, he got on top of me and entered me. It felt a bit tight at first, but once inside, it slid in smoothly. He thrust deep into me, and I struggled hard to stay quiet. When I said, "Let's switch," I climbed on top of him. The angle rubbed against my clit, feeling amazing, and I rocked back and forth without caring about the creaking bed. When he said, "I'm about to cum," I felt a little unsatisfied, but said, "Go ahead," and started moving faster and harder until he came. After pulling out, we got dressed and I quickly returned to my own bed. That night, I kept replaying it in my mind, touching myself over and over to relieve the wetness. In the morning, I acted normal. I decided to pretend it never happened.
