Everything happens for the first time in person's life and the cutie understood the truth of that saying that night.
Before that night, she and her boyfriend made sex but a usual one. That night, they came up to an idea of making passionate anal sex. Of course, the dude understood he would have to work hard with his tongue and hands before the cutie would take his dick into her anus but he was ready to do it.
He licked his girlfriend from head to clit, ate her slit and stretched her tiny asshole with his fingers when she told him to thrust his rod into it.
