mega ultron cumshot 

When you cum so hard that your balls retract into your body, along with your legs until you fold into yourself and turn into a car like a transformer.

You: Hey mum, when did you get a new car?
Mum: Oh that’s just your best friend. He had a mega ultron cumshot after fucking me last night.
