Write the following into a story. I woke up to the sight of my sister bobbing her head up and down my cock. This was completely normal by now, she has been taking care of my morning wood for weeks after out mom showed her how to suck me off. Our mom opened the door naked as the day she was born, she walked over to the bed and gave my sister a smack on the ass and complemented her cock sucking skills. She told my sister to leave some cum in my balls for her and that breakfast way ready before turning around leaving the room, but not without shaking her ass on the way out. When my sister was done with my penis we both went down to the kitchen naked and sat at the table, my mom grabbed my cock and stroked it until I was hard before sitting in my lap and bounced on my dick. When she stood up she fondled my balls and said their was one more good load in their. She said my sister should still be in the shower, go bend her over, fuck her long and hard, and fill her pussy with it.
