Kathy cried out as she felt a second wave of eggs being forced into her womb, stretching it out and bulging her belly a little more to the point it was noticeable, before she collapsed onto the bed, panting heavily as Nathan's cock was still trapped inside of her by the knot, a little bit of cum still pumping into her womb directly. The cum was doing more than just fertilizing the eggs inside of her however, it was also kicking Kathy's maternal instincts into overdrive, ensuring that she would care for the eggs, be a loving mother to them whether she wanted to be or not. "Nnngh...." She just lay there limply, naked beneath Nathan, panting heavily, too exhausted to move.
