Cambodian Firetruck
The somewhat sexual act of having sex with a woman on her period, so the blood spreads on your wiener. But then with your ejaculant, you must put out her "flaming hawt" vagina.
So Tyler was fuckin Allison right, when she asked for a Cambodian Firetruck (By the way this is normal to be requested by both genders). So Tyler replied with his ejaculant all over her vaj, "FUCK YEAH!"
