'I didn't know anyone else was camping here,' said Michelle when Sarah swam up. Sarah looked a little startled and then politely introduced herself.
'Me neither. I'm camping here with some friends. My name is Sarah.' She extended a hand as the other treaded and Michelle gently shook it.
'Michelle. They coming down for a swim too?'
Sarah shook her head. 'Jenny is sleeping and I don't know where Heather is. I should get back to looking for her; she wasn't feeling very well today.'
'Want some help searching?'
Sarah nodded, though really she wanted to continue her search alone. Since entering the water she had felt oddly aroused and now she desparetly wanted some privacy in the woods to attend to her unusually intense urge. When they were close enough to the lake's edge that they could stand she had to look twice at Michelle's crotch, convinced that the thick, dangling cock was an oasis to her inflamed mind. She had to touch it to be sure.
'Mmmm, think you're friend can wait?' Michelle's cock quickly rose to attention. Having her own cock serviced still appealed to the shemale, and with any luck Sarah would be affected by the lake water in the same way.
Utterly mesmerized by the foot long shaft, Sarah dropped to her knees with a splash and wrapped her mouth around the plum-shaped head. Beneath the surface her hand worked furiously at her snatch, fingering herself so quickly that her cunt swallowed up the tainted water. Michelle lasted only a short time, her sensitive new body unused to the sensations, and her balls heaved its tainted spunk into Sarah's hungry mouth. She swallowed the first load greedily, then threw her head back and screamed with pleasure as her heated body wracked her with orgasm. Every streak that splashed across her face tightened her cunt around her fingers until her face disappeared beneath the musky cream and her hand was forced out altogether.
Sarah stood and wiped the cum from her eyes. She wanted to shovel the delightful splooge into her mouth but she was still panting from her orgasm and settled on wiping it across her ample breasts. 'Wow,' she said, regaining a smidgeon of her former composure. 'I always thought women like you were just male fantasy.'
'I did too before today.' Michelle brushed a finger across Sarah's cheek and sucked the collected cum into her mouth.
'Before today?'
'Yep. I used to be a man before I came to the lake. Then I drank the water and slowly transformed into the beautiful shemale I am now.' She moved to scoop another dollop of man-cream but Sarah stepped back.
'And wh.. what does it do to women?'
'It makes them beautiful shemales too,' said another voice. Sarah turned and saw a monster-titted woman with a huge cock jutting aggressively from between her legs. Although her body was radically different, her face was still undeniably Heather's.
