When a woman is on her period, take a fist full of baking soda and when fucking her, fist the baking soda into her pussy, now shake her up until there is a volcano explosion. She will love it. Note: This works with a beer bong filled with Ginger Ale leading to the vagina as well.

The result of one fapping for so hard and long that it is blood instead of semen coming out of the penis. It also burns terribly, making it seem hot like a volcano.
Patient: I think i have a little problem...
Doctor: And what might that be??
Patient: Well, I was fapping yesterday, and it was for a long time, and I started cumming blood!
Doctor: Ah, sounds like a volcano to me!! This morphine should do the trick.
