You do her

You spend the next 15 minutes slamming the hell out of her ass. At first she had begun eating Mel's pussy. But she was so weak, she could barely moan. "I'm about to cum," You moan. Both girls faces almost magically appear at your dick as long streams of cum spurt out on both of their faces. For a good 5 minutes they lick the cum off and snowball it back and forth between each other before finally splitting it and swallowing it. It was then you realize you only have 5 minutes left to be back at school.
