Eva's bulge had disappeared completely. Sliding her right hand in her swimsuit, she touched the area to make sure she wasn't dreaming. Her package was gone...
The area felt completely smooth, hairless and slightly rubbery. A delightful shiver went through her as her fingers ran over a sensitive slit. Her groin started tingling, warming to the touch.
"I am... female now?" Eva wondered for a second.
Suddendly a little nub started poking from the slit under her fingers. Eva pressed against it with the palm of her hand, eliciting a soft moan as the hardening nub sank back in the slit. As she removed her hand however, the thing sprang back, pushing against the fabric of her swimming bottoms.
"What... what is this!" Eva whimpered, pressing over the fabric with both hands. Something throbbed in response, a sinuous shape that thickened under her palms and slipped through one of the leg opening, perking up. Eva almost screamed in surprise.
"Is that... a dolphin penis?!"
She pulled her bottoms down with one hand, wrapping her fingers around the thing with the other to examine it. It sent another shiver of pleasure through her spine, and it throbbed in her grasp, contracting in an alien way. The thick base pulsed visibly, while the tappering end squirmed in the air, oozing pre.
Eva immediately let go of the strange member to avoid getting fluids all over her hand. She stood alone in the girls' locker room, staring bewildered at her dolphin penis as it throbbed lightly in the air, her swimming bottoms deformed by the shape of the base it barely covered.
