Make her cum...hard.

You decide that although you would like to **** her a bit more, you simply need to get off again, so you keep fucking her tight hole, harder and harder, and then she cums , shooting vaginal fluids from around your massive dong, screaming "OH GOD! OHHHH GOOOODD AAAHHHHH!"

A moment later, you do the same, firing your steaming load into the depths of her cunt.

Finally, you go towards the bed in the corner, and fall asleep.
