It was my third time. 1 in the morning. Squirting my c** into my little sisters mouth as she slept. She was nursing the sperm from the tip of the head of my c*** and swallowing. I was ghosting my fingers on her hairless little c*** and tiny breast buds. I was almost finished with my o***** gently thrusting and stroking my c*** when her eyes flashed open. The moonlight made it all clear to her except to who I was. She screamed like a girl in a horror movie! Mom was there faster than Wonder Woman and there was no doubt that I was doing something wrong. My very cute sister was 12, I was 13. Mom calmed sis down as she tried to beat me to death with her hands and anything she could grab. I completely deserved it. She told us to get cleaned up and get to the kitchen. Haylie had c** on her face. She sat us down at the table with glasses of water and her doctored coffee. I wanted to c** again and my boxers were tented as mom laid it on the line. She was wickedly mad, but understanding. We all had s**. Then we cooked breakfast together and slept in her huge bed. Mom did her work stuff from home as I fucked my sister. A learning time no doubt.
