Haku glanced down at himself nervously, clenching and unclenching his hands as he waited to feel something indicating the potion was kicking in. A crack sounded through his back and hips as they began to shift all at once. "A-- Ahh!" He gasped, placing his hand on his hips as they strained against his shorts. The change was noticeable, his waist tapering inward while his hips flared on and grew more feminine by the second.
"H-- Holy shit..." Haku stammered, his voice laced with a girlish inflection. His boxers slid off, exposing his shriveling manhood to the cool air. She blushed furiously and slid a hand between her thighs, feeling her testes ascend from the increasingly taut and now-empty sack. What would sexual pleasure feel after you finished the change? It's impossible not to think of such things as your pecs rapidly inflate into tits capped by pink, sensitive nipples. As this occurs, her labia forms from her scrotum's remains, splitting down the center and reshaping into perfectly shaped, feminine folds. "F-- Fuck..."
"I didn't think it would happen so fast!" Haku cries out, her voice fully transitioning to a feminine frequency. She squeals as her breasts and ass pulse and grow, reaching their finalized, perfect and perky form. As this occurs, her vagina and urethra pop open as she brushes against her clit in awe. She felt the whole process as the male sex organ shrunk into a tiny, sensitive nerve bundle nestled within her vulva. A fluffy tail bursts from Haku's backside, quickly flourishing and growing while her new, fluffy, and pointed ears stick from atop her head. She'd have to be careful not to bite her tongue with the new fangs in her mouth.
After regaining her composure, Haku looks at Ren with crimson cheeks. "Don't just stand there! Do something!" She yells at her friend, who stands with mouth agape and eyes wide with awe. She has no idea how arousing it was for Ren to witness his best friend undergo such a sensual transformation.
"What am I supposed to do? You're the one who drank the potion!" Ren reminds Haku.
Nervous sweat beads upon Haku's smooth, milky skin. With a sigh of concession, she turned from Ren and dressed in feminine clothing, with a white blouse, a black mini skirt, and black thigh-highs. She bites her lip as she pulls the panties up and snaps them into place over her vulva, which writhes and pulses under the taut fabric. With these clothes, any semblance of masculinity Haku had left was thoroughly eviscerated. She turns to see an embarrassed Ren getting ready to speak. "No! I don't want to hear it! I just want to get this done and over with!" Haku pouts angrily, hugging her pillow while glaring at her friend.
Haku presses her thighs together, the thigh highs pinching her creamy flesh just right. In this position, she's firmly reminded of her missing manhood, her pussy still fuzzy and warm from the white panties rubbing upon the sensitive flesh. Despite her outward anger, Haku is more bothered by a different, unexpected emotion bubbling within her. Pride? Excitement? Regardless, she could never let Ren know she might enjoy this sultry new body.
"Just take the pictures so I can turn back!" Haku shouts, pouting as she sexily clutches the pillow, legs quivering.
"By the way... How do you know you're going to turn back?" Ren asks the question that had been lingering in the back of both of their minds. He assumes Haku has it figured out already.
Haku quickly hops to her feet with a determined look, grabbing the other half of the potion as she abruptly approaches Ren and holds it to his mouth. "We'll just have to find out together, won't we?" She asks with an utterly wicked grin.
