Long-shot but I'm trying to find a vid I saw on pornhub around 8 years ago
It's a hentai with a purple hair girl getting gangbanged in park at night. She's getting fucked by 3 guys while 20 other guys are on the side watching. The girl isn't human and has power to make the guys dicks erect and bigger. She's getting fucked pretty rough until she collapses on the ground in the end.
Video is around 6min and felt like part of a series, not sure on that though
Any help would be appreciated
