After the very strange morning my family had, I was sore and ready to go back to sleep. Unfortunately I was still in my father's bed watching my step mom lick his cock clean of cum. Cum that happened to be soaking into my pussy right now as I knelt with my ass in the air with strict orders not to move.
When his dick was clean, Daddy told my step mom to crawl over in front of me then got up and stood beside the bed so he could adjust our bodies how he wanted them. He put her right in front of me, knees bent and put her hands on them holding them open. I was left on my knees with my face inches away from her pussy. Daddy used his fingers to rub her a little, spreading her lips opens showing me how wet she was. The bare lips of her pussy and her upper thighs were glistening with the juices dripping out of her, so I knew that like me her reluctance didn't lessen her arousal.
As she started to moan and wiggle her hips against Daddy's hand, he pulled his hand away and pushed my face against her. "Your turn. Lick that pussy slut, make Mommy cum. See how wet you made her, riding Daddy's cock like a whore in front of her."
