Holy shit guys. I can't believe what just happened.
For context, i'm 16M, my little sister is 5F. During quarantine, i've been playing a lot of Animal Crossing with her. We got a pretty cool world, she loves to play the game. So yesterday, she was playing it all alone in the living room, I went to take a peek, when i saw Isabelle on the screen. Holy shit. My cock got so fucking big. I could see the veins of my fat cock through my pants. I thought no one was home, so I started slapping the sausage to Isabelle on my little sister's screen. After 3 minutes i was about to cum. I could feel the thicc nut coming in Isabelle's tight inner dog pussy. When i could feel the cum coming, I heard footsteps behind me. Holy fuck. It was the fucking cleaning lady. I'm so fucking scared, what do i do? How do i explain i wasn't beating it to my sister but to Isabelle? Reddit, please give me some advice!
