"Are you crazy Karyn!" That was all Jon could utter any further before his ability to speak was cut short and he fell silent as a strange feeling enveloped his body. Despite the heat in the air and on the sand at his feet Jon felt cold and a bit light headed as he realized that he no longer had a voice and he felt weaker then usual. Suddenly Jon felt himself drop down in height by around a half a foot almost like his legs fell into themselves even though that's not what happened. Meanwhile he felt like his arms and the rest of his body shrunk in equal measure. Suddenly needing to look up at Karyn as she smiled at him, her lust apparent was alarming as now she dwarfed him by several inches. All of this was disturbing to Jon but what was most disturbing of all was what was happening to his body.
Feeling strange happenings in his body Jon's eyes shifted downward away from Karyn's gaze. The sight that greeted him proved his earlier suspicions correct for he did look smaller in stature but his swimming shorts weren't supposed to be that tight. Right before his eyes his baggy red shorts tightened considerably on his legs until they resembled spandex and then the leg portions began to receded up his thighs inching closer and closer to his crotch. Not able to move Jon looked on alarmed as he felt the tightness increase even as the garment itself got smaller and smaller. The shorts reshaped themselves as they receded and within seconds they had become a speedo but the tightening still continued. At this moment Jon saw his legs reform into that of the form and shape of a feminine girl his age and his feet joined his legs in the process as they became smaller and more dainty as pink nail polish appeared on the manicured toenails. As the changes continued up his legs to his crotch Jon found himself gritting his teeth in pain as the tightness of the speedo increased. The speedo looked like it was about to rip it was so tight on the bulge of his crotch but suddenly the pain ceased as the bulge flattened and Jon's gait shifted with the emergence of a noticeable thigh gap. The speedo's sides morphed into a loose knot as its color shifted from that of red to bright pink. Suddenly Jon wasn't wearing swim trunks anymore but a pink string bikini bottom.
The changes continued upward more quickly now as he felt with noticeable discomfort his chest bones snap around and reform into that of a petite hourglass shape. Jon was disturbed when he felt a phantom piece of fabric suddenly appear on his back and snake around to his chest on its own. The fabric was a piece of bright pink string and he had an idea of what it's purpose was considering the nature of Karyn's wish. Suddenly very quickly his flat chest expanded and within seconds he sported a hefty pair of C-cup female breasts that had been covered by the fabric as support cup formed while his breasts inflated. Jon was mesmerized by his new 'girls' and how big they were. The pink string bikini top barely held them up. Jon was so distracted that he only realized minutes afterward that all hair on his body except on the top of his head had disappeared and the short light brown hair that had sat on top beforehand now cascaded past his shoulders as they tickled his skin. Within a minute afterward the finishing touches and bodily augmentations had concluded and Jon was no longer a forgetful he but a very noticeable she.
Looking back up at Karyn Jon in a high-pitched girly voice that partially disturbed her could only gripe "Just great Karyn! Don't you know from your breasts and hair mishap that we can't..." At that moment Karyn couldn't hold back any longer and lunged forward planting her lips on Jon's and sliding her tongue inside Jon's mouth. Jon was stunned but it felt incredible for her too as she forgot about her troubles, closed her eyes, and wrapped her arms around Karyn's neck and Karyn did the same with her arms around Jon's back. Karyn's breasts encased in her sport one-piece swimsuit rammed up against Jon's in her bikini.
