Never had

"Lindsey, up here!"
Lindsey looked up at the mezzanine and saw Ian, in her body, resting her tits on the balustrade, a dildo in her hand.
"Get my body dressed right now!" She cried, stomping her foot.
"Oh, not yet," Ian said. "I'm having too much fun."
He leaned his head on a hand and idly sucked on the dildo, closing his eyes as he licked up and down the rubber shaft, the tangy taste of his cousin's pussy delicious on his tongue.
"I'm telling your parents."
Ian snorted. "The rules were: no sex with each other. Not: no sex with yourself. Although, if you want to break that rule I'm still wet."
Ian stroked his tits seductively, enjoying the feel of his cousin's taut breasts as they bounced beneath his touch.
"Gross," she said, crossing her arms and walking off in a huff that didn't suit Ian's stocky body.
Ian hadn't wanted to visit Swap Resort with his family. He figured he'd get swapped into the body of some old ugly guy. Instead, to his surprise, Ian found himself in the body of his hot cousin for the weekend.
His hidden attraction to her didn't stay hidden for long. He locked himself in his room for long hours to stroke himself, before slipping into a tiny bikini and walking around enjoying the attention. He'd never been attractive before. Never had people hitting on him all the time. Never had access to tits and a pussy that were constantly crying out to be touched.
