That was not hugging, that was cocooning, and she was the butterfly.
The male (Or Herm) will do this Solo and will repeat this process onto the cocooned victim as much as possible until the female is not visible.
Suggested to practice against walls, floors, or even ceilings (The last being most difficult. Like standing, the cum will drip downwards thanks to gravity and only a slight portion of her will be covered.)
The act of doing this to multiple persons is called Hive Cocooning
Person A: "So, did you hook up with Cindy last night?"
Person B: "Hell yeah, man. I was saving up all month to Cocoon her."
Person A: "So?"
