Evelyn decides to fill Thunder back up, she's sure that her grandparents will understand. She sticks her remaining hand on Thunder's cock slit and presses it forward, into the cock, sliding up her arm, Thunder notices what she's doing, and thrusts his cock up her arm and around her head and up her neck.
As Evelyn travels down the shaft, and her hand gets closer to the sack, she realizes that she can't feel the tips of her fingers, upon closer inspection, her fingers have already started becoming cum, just like her arm before, soon her shoulders are through, at the same time, Evelyn can feel a more open space with her fingerless hand, that's right, she was almost at the balls of Thunder, her dream was about to come true.
On the outside, Thunder humps into the soon to be orgasm into his cock, pushing down her boobs, then her waist, making quick work of his free refill. Back inside, Evelyn is finally able to see the inside of the balls, and what was her hand is now a slop of cum, she could also feel that her hips were now feeling constricted, and soon enough, when her forearm is all but cum, and her hair is sweating with white, she is fully inside the cock, but here legs have yet to join her.
Evelyn tries to enjoy it as much as she can, but her mind starts to slip, this is it, I'm nothing but horse cum. Those were Evelyn's last thoughts, as her head and mind, turn into cum. Thunder was close to climax yet again from all the inside stimulation, though he still has a semi solid body inside him, he ejaculates down his shaft, the cum goes around Evelyn's body, instantly churning it into cum, and bringing it out with the rest of the cum.
Now that all of the people were fully gone, Thunder was at peace again, ready to go to sleep.
