Pull out and cum all over her

You continue to fuck her tight ass as quickly as you can, before the urge to cum overtakes you and you release a burst of cum in a torrent just as you pull out. Your cock explodes, spurting cum over her big, round ass, a string of your seed spurting down her ass crack as she groans in join. You grab your cock, quickly jerking it as quickly as you can as you continue to cover her thick, juicy, burning ass in your cum.

With that, Lilith begins to grow warmer, the heat of her body emanating and warming your cock and balls even from the distance. The cum seems to be absorbed into her skin, or perhaps steaming away, as she begins to glow with a strange power. After her ass is cleaned of cum, Lilith twirls through the air with a whirlwind of flames as you step backwards, and she pauses, staring at you with eyes of fiery passion.

"That's better," Lilith says, as she begins to glow with infernal power. "Now I have the strength to finally do something."

"So, what now?" you ask.

"As attractive as your body might be, it's not too intimidating or safe for you to go around nude. Get dressed and take whatever's in the box. It belonged to my former ally. Then, we begin our quest."
