"Let me show you how to use this," Aaron said, reaching around his former body and snaking his hand into the shorts to grasp his former cock between his slender new fingers."Whoa!" The woman in his body jumped, staring down at herself as her cock grew hard.It was Aaron's second day at Swap Resort when he'd found himself inside the body of this gorgeous stranger. He was walking down to the pool dressed in a skimpy bikini when he saw his old body. It wasn't uncommon to see random couples pair up and fuck by the side of the pool or in the restaurant. Though the woman in Aaron's body was surprised she let him continue to stroke her. Aaron pressed his tiny body up against his hard one, marveling as the cock grew in his hands. God, it felt so big in his tiny fingers and he giggled, wondering what it would feel like inside him.The woman must have wondered, too, because she turned and grabbed his ass to pull him close. Now Aaron's thick cock was pressed against his stomach, trapped between their two bodies as they made out. Heat blossomed between Aaron's legs and he could feel his pussy lips growing slick. Soon enough he was bent over the nearest table, welcoming the full length of his former self into his tight new body. He moaned as he was spread apart, fire licking his insides, building up towards a tremendous release.
