Plug up her mouth.

You look around you for a bit before finding an eight inch long dildo lying nearby; perfect for stopping a leak. You grab the fake appendage and stuff it inside your cum-dump's mouth before the puddle on the floor can get any bigger. She gags and moans around it as her body's rocked by another orgasm and her stomach begins lifting her off the ground a few inches as she's stretched out once again by your seemingly endless supply of cum.

On and on it goes; pouring a seemingly endless supply of cream into your poor friend as she's stretched out over the course of several minutes by your titanic orgasm. You lose track of the time as she expands to the point where her arms and legs don't touch the floor and you have to stand up to keep pouring your thick and heavy cream into her.
