I was lying in bed, trying to fall asleep after a long day when I heard the door creak open. Vikusya, my little sister, poked her head into the room, giggling and holding a glass of water.
"I need to use the bathroom," she announced, climbing onto my bed and plopping down next to me. "But I'm too lazy to get out of bed."
"Just hold it in," I groggily told her, rolling over to the other side of the bed.
"Lazybones," Vikusya taunted, threatening to "accidentally" spill the water on me.
I sat up, now fully awake, and tried to take the glass from her. She playfully dodged my attempts, and we ended up in a playful scuffle. During the scuffle, Vikusya lost her grip on the glass and it spilled, soaking my shirt.
"Shoot, I'm sorry!" she exclaimed, as I glared at her. "I really need to go to the bathroom now."
I sighed and told her to "just go" and rolled over to the other side of the bed. Vikusya, unable to hold it in any longer, peed in my mouth.
I spit out the pee, shocked and disgusted. "What the hell, Vikusya?!" I yelled.
Vikusya, now embarrassed, started to cry and apologize. I looked at her, tears streaming down her face, and felt a pang of guilt for yelling at her.
"It's okay," I told her, as I got out of bed and went to the bathroom to clean up. "We'll clean this up in the morning."
It was definitely an unexpected night, but I couldn't stay mad at Vikusya for long. She was my little sister, after all, and I knew she didn't mean to do it. I just hoped she would be more careful in the future.
As I was getting ready for bed again, I couldn't help but feel a little bit turned on by the whole situation. The thought of Vikusya's warm pee on my lips and the sight of her crying and apologizing was a strange mix of disgust and arousal. I shook my head, trying to rid myself of these thoughts. It was wrong, I knew it was wrong, but I couldn't help the way my body was reacting. I tried to focus on something else, anything else, but my mind kept drifting back to Vikusya.
I climbed back into bed, trying to fall asleep, but my mind was racing. I couldn't stop thinking about Vikusya, and the more I thought about her, the hornier I became. I couldn't believe I was feeling this way, but I couldn't deny it either. I was starting to get wet, and I couldn't help but touch myself.
I started to rub my clit, imagining Vikusya's fingers on me instead of my own. I imagined her licking my pussy, her tongue flicking my clit as I moaned in pleasure. I imagined her finger fucking me, her fingers deep inside me as I came hard.
I came hard, my body shaking as I rode out the waves of pleasure. I lay there, panting and sweating, trying to catch my breath. I couldn't believe what I had just done. I had just masturbated to the thought of my little sister. It was wrong, I knew it was wrong, but I couldn't help the way I was feeling.
I fell asleep, my mind still racing, my body still tingling with pleasure. I knew I had to talk to Vikusya about what had happened, but I didn't know how. I didn't know how to tell her that I had masturbated to the thought of her, that I had fantasized about her peeing in my mouth. I didn't know how to tell her that I was attracted to her, in a way that I knew I shouldn't be.
