Sophia was now tied to sticks that I drove in the sand earlier to keep her legs in position and we have dragged a large rock under her to make sure her back would stay in the same arc. We ate and drank between fucks, but other than that I mostly spent the last hours resting or doing my fuck whore of a mother.
Eventually she got tired of always forfeiting my jizz to my sister, so she came up with an idea. "You want to make sure you sister gets fertilized? Than I have an other idea to speed up the process..." With those words she walked straight to her daughter and began caressing her ass.
-OK baby, you're willing to do anything to get those fucking incestuous babies, right?
-Yeah...
-Alright then, relax and let me do something for you. But let me tell you right now: it'll hurt like hell.
Without even waiting for a new answer she stabbed three fingers up my sister's overflowing pussy, licking up all the cum dribbling out and keeping it in her mouth. After a while of fingering she pushed her little finger and her thumb in before forcing her whole fist down my sister's sore cunt. Sophia groaned deeply out of a mix of pain and lust. After some more stretching, the crazy bitch that was my mother began sliding three more fingers in my sis's stretched out fuck hole. She was grunting and yelping harder now, trying to keep herself from shouting. Although she clearly was in pain, that little bitch in heat was progressively getting into it. As Mom jabbed her with more fingers, she came and squirted for the first time (first that I know of). Her own cum spayed all over our mom's face and she smiled a slutty smile with her mouth full of my own cum. Moments after, Mom had both her hands inside Sophia and after a bit more fingering my slutty little sister screamed, but I mean she really screamed like hell. "OUCH! OH MY FUCKING GOD! MOM! OOOOOOOOOH! IT FUCKING HURTS!" As she screamed like a fucking firetruck, Mom poped her knuckles out of my sister's painfully stretched cunt and spread it open with her fingers while rubbing her rectum with her thumbs. That's when I understood her idea; she managed to force her cervix open and was holding it open while pulling it up. Then, as my well fucked sister kept screaming, she placed her mouth over her saggy cunt and opened up to let all the cum she drained out of her mouth and straight in my sister's womb. The show was intense and unbelievable. Once her mouth was empty again she turned around, locked her lips on my cock and quickly milked a new load to add to the rest; after that she allowed her fingers to slip out and left my sister there. "Alright, now you can pump ME full of cum too. Come on son, come here and make sure your fucking slut of a mother is knocked up too!" |
