"Goddamn, I taste good," Ethan said, finally coming up for air."Are you ready for your final wish, master?" The bored genie asked."Not yet. Maybe in a minute." Ethan said, sticking out his tongue and thrusting his face back into his slick, warm pussy. His juices dripped down his chin and his musky scent filled his nose as he ate himself out. His tongue flashed through his pink folds as another tremendous orgasm built within him.Ethan had found a genie, obviously. His first wish was that he was in the body of Megan, one of the hot grad students that taught his chemistry tutorial. His second wish was that he was flexible enough to lick his own pussy.And there Ethan had remained, his legs thrown over his head, his tongue working it's way deep into Megan's delicious cunt. He feasted on himself for hours, enjoying orgasm after orgasm while the genie watched on."God," Ethan said, finally lowering his legs, exhausted and warm. "I wish I could do that forever.""Done," the genie said, snapping his fingers and disappearing.Ethan bent his legs back over his head and stuck out his tongue. He hadn't meant to phrase it as a wish, but there were worse ways to spend eternity. He slid his tongue inside his tender velvety folds and began licking himself once more.
