Being fucked by the Nightmare is the most depraved thing I've done so far, and I've done alot in this world already! My brain - real or virtual - floods with pleasure as I enjoy the sensation of being filled with horsecock, and my daughter suckling on my breasts only enhances the sensation!
With a great cry I orgasm on the horsecock, squirting my love juices. I can feel the large volume of horse cum swirling in my womb, but my greedy daughter is keepnig it for herself, letting the horse fuck her as well as me. I stay impaled on the horse cock for a few more seconds, enjoying the thick girth in my body before I slowly extricate myself from it and prepare myself for the next phase, my daughter laying eggs in me to absorb the cum and thus enhance her own abilities!
Spoiler (click to show/hide):
I'm basically presuming the eggs the slime lays are ability absorbing things, so they drink up the condom and then get eaten by the slime later on to complete the transformation. this sound ok to you?
