Go all in.

You grab her urethra and pull her open wider. You see her eyes bug out and you stick your head inside. You inhale the most concentrated cum scent you ever smelled. You feel the cock flex around you and open your mouth for the deluge. Her slit clamps down around your head and cum blasts down your waiting throat. You don’t even need to swallow.

Unfortunately, it also flows into your lungs. And eyes. And ears. All with massive pressure. You are shocked and can’t pull your head out. You feel your belly growing but also your lungs. They quickly burst and you drown with your head inside of her dick.
